PREFATORY NOTE.

In the act of Congress making appropriations for the Department
of Agriculture for the fiscal year ending June 30, 1889, provision was
made for botanical exploration and the collecting of plants in little
known districts of America in connection with the U. 8. National
Herbarium; and since that time a similar provision has been made
annually. Asa partial result of this appropriation the Division of
Botany has issued heretofore two completed volumes, II and Iv, of a
series of publications entitled Contributions from the U. 5. National
Herbarium. The present volume, issued in nine parts, is made up
chiefly of reports on collections made by Dr. Edward Palmer in the
southwestern United States and adjacent portions of Mexico, together
with other collections made by agents of the Government.

‘LIST OF PLANTS COLLECTED BY DR. EDWARD PALMER IN

LOWER CALIFORNIA IN 1889.

By GrorcE Vasey and J. N. Rose.

In volume xt of the Proceedings of the U.S. National Museum we
published an account of the plants of San Quentin and a partial report
on those collected about Lagoon Head. Thepresent paper will begin with
the Lagoon Head plants, and will include alist of the species of Cedros, San
Benito, and Guadalupe Islands. Mr. 'T. 8. Brandegee, of the California
Academy of Science, collected over some of the same ground visited by
Dr. Palmer, and has rediscovered several of the new species described
in the former paper. And now several of the species recently described
by him are included in the present list. We are indebted to a number
of botanists for assistance in the working up of these plants ; especially
to Dr. Sereno Watson, who has carefully looked over doubtful forms,
and to Mr. William Canby, who has generously loaned us many speci-
mens. Other botanists who have aided us in identifying species will
be referred to in the proper place. In this paper we give reference to
the first publication of the species, under the genus in which it is now
included, when not found in the Botany of California or Gray’s Syn.
Flora.

PLANTS OF LAGOON HEAD.

A partial list of the plants of this region has been published in the
Proceedings of the National Museum, vol. xi, pp. 534-536.

Lagoon Head, Lower California, the Cabo Negro of the old Spanish
charts, is a high, dark-colored headland of voleanie origin; its highest
point is 475 feet above high-water mark, and in clear weather it can be

‘seen at a distance of 30 to 40 miles, presenting the appearance of an

island.

794. Eschscholtzia peninsularis Greene. Bull. Cal. Acad., I. 68. In the sand
plain back from the ocean. Only a few plants found in bloom.

823. Eschscholtzia minutiflora Watson. Found in a cation 30 miles inland,
growing in sandy soil; “roots quite red.” If this is correctly referred, the
rauge of the species is extended cousiderably southward.

Biscutella Californica B. & H. Mr. Watson thinks this may be distinct
from B. Californica. Dr, Palmer reports it very common on the sandy hills
and plain near the beach. The ‘ yellowish white” becoming purple in
drying.

Arabis pectinata Greene. Pitt, I. 287. This recently described species of Mr.
Greene was collected this season by Lieutenant Pond at San Bartolome
Bay and also on Cedros Island by Dr. Palmer. Collected on sandy spot
among hills 40 miles back fromthe ocean, ‘ Bloom white changed to mauve
by age.”

Sisymbrium Brandegeana Rose, n. sp. Annual, glabrous, slender, simple
or branching, 6 to 15 inches high: leaves small (1 to 2 inches long),
pinnately divided into a few filiform segments: petals one and one-half
lines long, twice the length of the sepals, white: pods three-fourths of an
inch long, terete, horizontal, or sometimes becoming reflexed, sometimes
straight but mostly curving upward, tipped with a thick, obtuse style (one
line long), on short pedicels. Common in shady soil about the beach.

Drymaria viscosa Watson. Proc. Amer. Acad., XX, 467, A very common
plant on sandy places near the ocean, The plants grow in great mats cov-
ering the sand. Only before collected by Mr. C. R, Oreutt in northern
Lower California and by Mr. Brandegee at Magdalena Island and San Gre-
goria. Dr. Palmer has collected a large quantity of this plant.

Erodium Texanum Gray. Common on gravelly hills.

Fagonia Californica Benth. Grows among rocks in a cation 30 miles inland-

The same. But three plants found on the hills uear the beach,

Phaseolus filiformis Benth. Very common on the sand hills near the beach,

Lupinus Arizonicus Watson. Common on the sand plains back of the beach.
Some flowers are white, others are drab-colored.

Calliandra Californica Benth.

Astragalus triflorus Gray. Very abundant near the beach.

Hosackia glabra Torr. A very common plant 40 miles inland, grows com-
pact.

Hosackia maritima Nutt. Sandy, level piaces, 15 miles from the sea; bloom
yellow.

Hosackia rigida Benth. Stems flexuose, much branched at base; leaves
sessile, with small leaflets. Peduncles long (2 to 4 inches). Pods almost
terete, 14 to 2 inches long. “Found in a caiion 30 miles inland. The plant
most resembles Palmer’s (175), 1876, from Arizona.

H. Bryanti Brandegee. Proc. Cal. Acad., 2d. ser. II, 144,

CHnothera crassifolia Greene. Bull. Cal. Acad,, I. 156. Stems annual or
biennial, glabrous and very glaucous; leaves linear or narrowly lanceolate,
entire or sinuately toothed. Capsule linear, much contorted. We have not
seen Mr. Greene’s type, but the plant does uot seem to be the same as
Orcutt’s specimens. Very common on the sand hills and depressions near the
beach. ‘Showy colored flowers,” more or less purplish on drying.

Ginothera septrostigma Brandg. Proc. Cal. Acad., 2nd. ser. II, 156. Sandy
plains; 10 miles inland. Part of type.

CEnothera angelorum Watson. Proc. Amer, Acad., XXIV. 49. Forty
miles inland,

Filago Arizonica Gray.

. Viguiera Purisimae Brandigee. 2d. ser, II. 173.

Franseria dumosa Nutt. This is the same as Palmer’s 559 (from Los Angeles
Bay, 1887). The leaves are much more coarsely cut, and the spines hardly
flattened and hooked at tip. A compact plant 2 feet high, abundant on the
hills near the sea,

. Franseria Bryanti Curran.

11

793. Viguiera laciniata Gray. Three to four feet high. In stony ravines 30 miles
back from the ocean, and there common,

826. Helianthus dealbatus Gray. Clearly an annual; quite common on the sand
hill near the beach, growing thickly together. This is the most southern
station of this species, Besides the station given in, Syn. Flora, is to be
added Orcutt’s Locovrs (1886) plant; also at Ensenada and recently Santa
Margarita Island, by Mr. Brandegee. For thisspecies Mr. Brandegee takes
up Bentham’s old specific name of ELncelia nivea and writes H. niveus.

822. Encelia frutescens Gray. Common on the hills 40 miles back from the ocean ;
3 to 4 feet high.

828. Encelia Ventorum Brandegee. Proc. Cal. Acad., 2d, ser. ii, 175.

795. Leptosyne parthenioides Gray. Var. dissecta, Wat. Proc. Am. Acad., XXIV,
36. Dr. Palmer says this plant has a wide range on the sandy plains and
hills. Seen 40 miles back from the ocean; bloom at first white, but soon
becoming purplish. The margin of the akenes are incurved in age, with no
pappus, muriculate on the back. The only other collection of the species,
that we know of, is that of Palmer at Los Angeles Bay. This plant Dr.
Watson took to be the Acoma dissecta of Benth., but the rediscovery of that
species by Mr. Brandegee the past season shows that they are not the same.
Therefore Palmer’s Los Angeles plant is the type of LZ. parthenioides var.
dissecta Watson, and is not to be confounded with L. disecta Gray.

787. Amblyopappus pusillus H. & A. Very abundant on hills.

782. Eriophyllum lanosum Gray.

778. Cheenactis lacera Greene. Pitt., V, 29. This species was first collected by
Lieutenant Pond, at San Bartholome Bay, in March, 1889. Dr. Palmer col-
lected it about the same time in considerable quantity. It grows in low
sandy places near the ocean, Said to be a very fleshy plant. The stems and
leaves purplish. ‘ Bloom white” or turned by age to rose.

786. Dysodia anthemidifolia Benth. First collected by the Sulphur, also Dr.
Streets, recently by Lieutenant Pond, at San Bartholome Bay, and Brandegee.
Very common on the sandy plains, near the sea-beach, and extending for miles
back from the ocean. Dr. Palmer says it is a showy plant for cultivation,
with bright amber-colored flowers and an odor like the African Marigold.

817. Malacothrix Californica D.C. Flowers ‘showy, yellowish white.” Outer
pappus three to four persistent bristles. Sometimes with branching scapes.
Lemmon also collected such a form in 1875. So far as we know this species
has not before been found out of California, Dr. Palmer reportsit very com-
mon in the sand-hills about the bay.

814. Philbertia linearis Gray. A small trailing plant about 3 feet long, twining
about bushes or prostrate on the gronnd, often rooting at the nodes. The
older stems develop a very thick corky bark. The whole plant is glabrous,
except the inflorescence, which is very pubescent, The flowers are “ canary
white.”

774. Gilia Jonesii Gray. Only a few plants seen and these all collected in the hilly
country, 40 miles from the ocean. This species is only known from Jones’s
specimen from the Needles, southeast California (1884). We have not yet
seen the type, but the species certainly goes into the section Linanthus, and
there is nothing in Gray’s meager description to keep it out of G. Jonesii.

780. Krynitzkia intermedia Gray. <A very common plant 25 miles from the ocean,

781. Krynitzkia maritima Greene. The nutlets often of two kinds, both matur-
ing. The glabrous nutlets acute on the edge. The leaves often broader at
the base.

829. Rumex hymenosepalus Torr. Called ‘Yerba Colorado.” Much used as a
medicine, especially in venereal diseases, tlesh wounds, etc. The young tops
sometimes used as greens in California.

12

788." Argythamnia serrata Muhl. Var. Magdalene, Millsp. Proe. Cal. Acad. 2d,
ser., ii, 221. Found in sandy places between the hills contiguous to seabeach ;
has very long roots,

785. Stillingia linearifolia Watson. Grows in the hollows between hills near the
sea beach among shrubs and plants, loose grower.

783. Huphorbia polycarpa Benth., var. vestita Watson. Hills 40 miles back
from the ocean. Plants quite scattering.

789. Euphorbia Pondii Millspangh, sp. nov. Annual, prostrate, spreading from
the base. Stems glabrons, (3 to 6 centimeters long), dichotomously branch-
ing. Leaves ovate, obtuse, entire, (14 to3 millimeters long, 1 to 2 millimeters
broad) ; petioles hairy, (one-fourth to three-fourths the length of the blade);
stipules large, bluntly triangular, margined with two to four fascicles of
ciliw. Intlorescence solitary in the upper axils, and terminal upon the
youngest branchlets; involucres turbinate, sessile, slightly hairy ; glands
four, transversely ovate, minute, dark red; appendages minute, white, or-
bicular, deeply two crenate-toothed on the margin, or wanting; styles bi-
furcate to the middle. Capsule trisnleate ; carpels carinate and slightly tu-
berculate ; seeds elongated, quadrangular, ferruginous between the angles.
Described from a specimen collected at Plaza Maria, Lower California, in
1889, by Lieut. Chas. F. Pond, U. 8. Navy; also Gandalupe Island by Palmer,
A form with smooth capsules and more turgid seeds is in this collection.
Hills 40 miles back from sea beach, the plants have a yellow shading when
fresh.

792. Buphorbia Xanti Engl. Typical specimens of both sorts, the white and the
red appendiculate, that prove the shyubbiness of the species. Abundant,
25 to 40 miles back from the ocean; loose grower, pinkish-white flowers.
Sometimes old plants are met with that have deep, rose-colored flowers.

775. Chorizanthe Vaseyi Parry & Rose. Bot. Gaz., XV, 64. A figure of this
plant accompanies the deseription. Among hills, 40 miles inland.

779. Allium Californicum Rose, n. sp. Bulbs cespitose, narrowly oblong with dark
red coats, deep seated (3 to 4 inches), scapes terete, 3 to 5 inches high:
leaves three to five, linear, mostly shorter than the scape: spathe two-
valved and these ovate, acute: umbel somewhat open, four to five rayed:
pedicels 5 to 8 lines long: flowers “dark mauve color,” with lanceolate-
acuminate segments: stamens and style included: capsule obtuse, with two
ovules in a cell, but one (rarely two) of the ovules mature.

A species closely related to A. hemetochiton, Wat. Hilly country 40 miles
back from the ocean; ‘‘ Grows in stiff clay ; odor strong of onions.”

654. Aristida Californica Thurb. This peculiar grass grows in small, compact
bunches, It has a wide range on sandy soil and gravelly hills. It is the
only grass in this section which affords forage for wild or domestic animals,
and as it is generally found (as shown by many of these specimens) denuded
of its leaves, while the flowers and seed-tops remain intact, the inference
would be that wild animals (domestic animals are few here) crop the leaves
while the grass is tender.

655. Festuea tenella Willd. Var. (very small.) A common grass, especially where
water is retained in sandy arroyos and plains. Seldom found with the ap-
pearance of having been cropped by animals.

651. Aristida bromoides H. B. K. Common on sandy slopes and places where
moisture is retained, growing so thickly that they seem sown for a lawn.

652. Triodia pulchella H. B. K. Found in tufts on a gravelly ridge.

653. Muhlenbergia debilis Trin. These, the only ones found, were associated
with 651.

* Euphorbiacee determined by C. F. Millspaugh.

CEDROS ISLAND PLANTS.

Dr. Palmer spent three days on the north end of this island, March
18 to 20, and made a large and valuable collection. His numbers run
from 677 to 764, and unfortunately are partly duplicated in the San
Quentin collection of the same year.

Mr. Greene has published (Pittonia, vol. 1, 200-208) a list of the
known species of this island, and also a supplement (l. ¢. 266-269) list-
ing ninety-one species. Dr. Palmer has added at this time forty-three
species to the flora of the island. Dr. Streets, who visited this island in
1876, and made a small collection, found here Abutilon Lemmoni, which
has not been since rediscovered. Mr. Belding has also collected here,
but not very extensively. The species now known to the island are
one hundred and thirty-five.

For convenience we give here all the species not given in Mr. Greene’s
list, and we also add in parenthesis, liis number after species found in

Only a few plants found and these on a level place. First described and
distributed as 7. Palmeri, but since Mr. Watson has written that it is prob-
ably his ‘7. erectus described from miserable material.”

747. Isomeris arborea Nutt. Plants about 4 feet high. (No. 3 of Mr. Greene.)
Also collected by Lieutenant Pond this season. Mr. Greene considered that
this species belongs to Cleome and calls it C, isomeris, Pitt. i, 200.

633. Frankenia Palmeri Watson. Common plant near the sea-beach. (No. 5 of
Mr. Greene.)

713. Polycarpon depressum Nutt. Collected only by Nuttall and Lemmon, in
southern California, although various things have been distributed as this
species, even Tillaa minima and Achyronychia Cooperi. Found under pine
trees at the highest point on the north end. (Altitude, 1,761 feet.) -

699. Spheralcea* fulva Greene. Pitt. i, 201. Only three specimens found and these
in flower. Collected by Dr. Streets in 1876. (No. 6 of Mr. Greene.)

752. Ziziphus Parryi Torr. jide Trelease. The following is Dr. Palmer’s note.
“A very thorny shrub, 2 to3 feet high, with numerous crooked branches, form-
ing a compact plant, good fora hedge. The fruit when ripe may be yellow,
as that color was indicated in some of the fruit seen.” In canons and
mountain sides apparently not collected before.

738. Rhamnus crocea Nutt. ‘The more acute leaved sharply toothed form,”
‘Trelease in lit. An upright growing shrub 6 to 8 feet high, In canons.
(Probably No. 7 of Mr. Greene. )

730. Rhus Lentii Kell. Proc. Cal. Acad., ii, 16. A large shrub 5 to 6 feet high in
canons. ‘A profuse bloomer; crimson colored to white ; fruit shiny, as if
iced Over.” Fruit a half inch long. (No. 9 of Mr. Greene.) Also collected
by Lieutenant Pond this season. By Dr. Veateli, in 1859.

735. Rhus integrifolia B. & H. Dr. Palmer says of this plant, “An irregular grow-
ing shrub, with short body and stiff limbs.” Much used by the fishermen
for fuel, for which it is very good. In cations. (No. 10 of Mr. Greene.)

682. Veatchia Cedrosensis Gray. Dr. Palmer’s notes are as follows: Not found
in bloom or fruit. A dwarf tree 5 to 6 feet high, dotted here and there over
the north end of the island. The wood is soft and spongy, shrinking when
cut, leaving little but the bark. Mr, Brandegee has identified this plant with
the Schinus discolor Benth. Bot. Sulph., p. 11, and has collected it from the
original station (Magdalena Bay.) In Proe. Cal. Acad., 2d ser., 2, 140,
he considers it a good Veatchia and taking up the oldest specific name,

- writes it Veatchia discolor. He also refers here Bursera pubescens Watson.
(No, 8 of Mr, Greene.) ,

721. Lupinus sp. This is the same as our 666a (distributed as 708) of former paper.
The plants are often smaller, the flowers larger (5 lines long), scattered or
somewhat verticilate; the bracts tardily deciduous ; pods four to six seeded.
Found on hill sides and cafons. A very showy plant ‘ bloom purple upper
lobes yellow.” As we noted before, our plant seems nearest L. Arizonica, but
it hardly answers for that and perhaps should be made distinct.

736. Hosackia maritima Nutt. The flowers are only 2 lines long; the pods few
seeded. ‘This is the same as the San Quentin 669a. Not before found on the
island.

698. Hosackia nudata (Greene). We have not seen Mr. Greene’s type, and yet there
is little doubt but that thisis his Syrmatium. Our plant is larger, with many
slender weak branches; the leatlets sometimes larger (34 lines long), often
obtuse, glabrate in age. Although many of the short peduncles bear but one to
two flowers, yet it is not uncommon to find three, four, and sometimes five
flowers in the umbel. The species of Syrmatium form a strongly marked

found by Dr. Palmer, is Abulilon Lemmoni, collected by Dr. Streets in 1376,

section of Hosackia, and it is an open question whether it should not be kept
distinct. Mr. Greene (in vol. ii, Bull. Cal. Acad.) thinks it should be, and
ably defends Vogel’s genus. Mr. Watson, while saying it might well be con-
sidered generically distinct, still retains it under Mosackia, and the same course
is followed by Mr. Brandegee in his recent paper. The discovery of a num-
ber of species belonging to this in late years would seem to emphasize the in-
dependence of the section. If it is so to be considered, the two recent species
of the authors (published in Proe. Nat. Museum, vol. x1, pp. 528, 529) should
be referred to as 8. Watsoni and 8, Palmeri. However, in the present un-
certain limitations of the genus, we accept the limits of Bentham and Hooker
in Gen. Plant, followed by Mr. Watson, in Botany of California.

733. Phaseolus filiformis Benth. Bot. of Sulphur, p. 13. This was collected in
1875 by Dr. Streets, and this season by Lieutenant Pond. Found in exposed
places facing the ocean; ‘ Bloom, white.” The plant has been collected near
the United States boundary by Orcutt in northern Lower California; also at
Carmen Island (Palmer, 1875); Guaymas, Mexico, Palmer, 1887; Xantus,
1859, and by Brandegee, in Lower California.

727, The same; mouth of canon; ‘bloom rose-colored.”

744. Dalea Benthami Branidg. Proc. Cal. Acad, 2nd ser, ii, 148. As already pointed
out by Mr. Greene this plant differs from the D, megacarpa in its persistent
stipular spines, the spikes are shorter and not so close, the terminal leatlet
retuse; ‘bloom, yellow.” A compact plant one foot high. (No. 16 of Mr.
Greene,) Collected by Lieutenant Pond, 1889, and distributed by Mr. Greene
as var. biuncifera Greene, aud also in this collection.

683. Astragalus fastidiosus Greene. Bull. Cal. Acad., I, 186. Commonin canons
in moist places; bloom ‘‘cinary-yellow.” Mr. Watson writes, ‘one good
character has not been noted, the articulation of the pod on the stipe,
which also occurs in one or two other species.” (No, 12 of Mr. Greene.)

685. Astragalus insularis Kell. Bull. Cal. Acad., 1,6. Before known only from the
specimens collected by Dr. Veatch in 1859, the species not being described
until 1877. Only afew specimens were obtained at this time, mostly in
fruit. It is to be regretted that a larger collection had not been made of
this rare and little known species. It grows in exposed places near the sea.
(No. 13 of Mr. Greene’s list, but not found by him.)

692. Astragalus sp. Annual; much branched and spreading at base, more or less
pubescent; branches slender: leaflets seven to eleven, 1 to 2 lines long, re-
tuse or sometimes linear, acute, and 3 lines long: flowers, one to three, min-
ute, (less than 2 lines long): peduncles 10 to 20 lines Iléng: pods 3 to 5 lines
long, slightly pubescent; the dorsal suture intruded, except near the apex ;
one-celled, incurved and reticulated. We have distributed this as 4. Cedro-
censis, but Mr. Watson thinks it is A. Nudtallanus, D.C., but pods always one-
celled, etc. Growing on level places facing the sea. ‘* Bloom pale-blue.

708. Tillzea leptopetala, Benth.* It seems to us that this species should be sepa-
rated from Tillea minima. It is probably 7. leptopetata of Bentham, but the

* Collected also by Palmer at Guadalupe Island. ‘‘Among plants in cofons. The
specimens are very red.” (No. 900.) The typical form of Tillaa minima Miers was
collected by Dr. Palmer, at San Quentin, in February, 1839, and distributed as No. 713
in part, and No. 714. A third species of Tillaa proper, T. connata Ruiz et Pav. FI,
Per. and Chil. I, 70, is to be added to our North American flora. The plants are
larger than 7. minima and not diffusely branched. ‘The sepals almost a line long,
ovate acuminate; the petals almost filiform. Collected also by Dr. Palmer at Sau
Quentin (718a), growing with 7. minima. Our plant seems to be the same as the one
collected under the United States exploring expedition of Captain Wilkes, in Peru,
and referred here by Dr. Gray, page 688. He considered it distinct from 7. rubescens
Hi. B. iK., but if the same it must still give place to 7. connala, the older name,

16

stems are quite red, while Bentham says of this species “ specimina haud
rubescent,” and was collected near the San Francisco Bay. The stems
are mostly single and erect, or sometimes with a few branches; flowers glom-
erate in the axils of the connate leaves, nearly sessile; the sepals nar-
rower aud more acute; seeds always two in each carpel. Shady spots in
canons.

753. Eucnide cordata Kell. Curran, Bull. Cal. Acad., I, 137. A loose growing
plant about 4 feet high; “ bloom yellowish-white.” At mouth of canon.
Collected by Dr. Veatch in 1859. (This-is Mr. Greene’s No. 20); he considers
it a Mentzelia, to which genus Kellogg first referred it, Mr. Watson thinks,
however, that the two genera should be kept separate.

751. Petalonyx linearis Greene. Bull. Cal. Acad., J, 18. Found in a ravine, ap-
parently comuon. About 2 feet high; ‘bloom white.” (No. 2l of Mr.
Greene. ) ,

712. Mentzelia adherens Benth. Both of Sulphur, p. 15. This plant differs
somewhat from Palmer’s 1887 plant, referred to this species by Mr. Watson.
The sepals are larger, their margins involute in age and rigid, Capsule not
angled, of a different texture; the seeds are grayish and much wrinkled.
Not given in Mr. Greene’s list, but collected by Dr. Streets in 1876. ‘* Bloom
canary color.” In exposed places. . °

719. Echinopepon minima Wat. Proc. Amer., Acad. XXIV, 52. Stems-glabrous
slender, 4 to 5 feet long, climbing over small bushes: leaves thin, smooth
below, white-papillose and scabrous above, triangular-cordate, more or less

three-lobed, 1 to 14 inches long. Sterile racemes (including peduncle) 3 to 4 —

inches long: limb of the flower 4 lines broad, pedunele 6 lines long: fertile
flowers mostly solitary, the peduncle becoming 8 to 9 lines long, fruit 6 to9
lines long (not including the beak), echinate with spine-like processes, two
celled, dehisciug by a deciduous operculum : cells three to six seeded, 14 lines
long, compressed, dark-colored.
By aslip of the pen Mr. Watson has reversed the character of the surface

of the leaf, and Mr. Cogneaux has copied the mistake into his monograph.
Vol. II, 805. At the mouth of a cation, Mr. Watson in Torry Bull, vol.
XIV, has re-established Naudin’s genus, separating it from Lchinocystis into
which B. & H. had thrown it, followed by Cogneaux, in Monographie
Phanerogamarum, vol. I. Our plant is the same as Dr. Streets, from Cedros
island (1866),

693. Mamillaria Goodridgii Scheer. Our specimen is doubtfully referred to this
species,

679. Apiastrum angustifolium Nutt. Growing in shady canons. Not before
reported from here, and the only known Umbellifer on the island.

689. Bigelovia veneta Gray. Only a few plants collected. ‘The whole plant
very glutiuous. (No. 34 of Mr, Greene.)

705. Filago Arizonica Gray. Side of cafon in moist shade. Not before found
here.

750. Gnaphalium Sprengelii H. & A. A few specimens found in a deep canon.
Not before reported from here.

731. Franseria chenopodifolia Benth. Very common, (No. 36 of Mr. Greene.)

757. Franseria camphorata Green, var. leptophylla, Gray. Proc, Amer. Acad.,
XXII, 309. Very common; a foot or so high. No 87 of Mr. Greene. The
variety also collected near San Fernando, Lower California, by Orcutt, (1886).
First collected on Guadalupe Island.

743. Viguiera lanata Gray. Very common plant on the island, and a large quan-
tity collected in full bloom. Collected by Veatch, Streets, Belding, and
Greene (No, 42.) ‘

Encelia Cedrosensis Rose n. sp. Shrubby, 4 feet high, somewhat scabrous
throughout: leaves opposite, sometimes alternate above, shining, ovate-lance-
olate, entire or repandly, toothed, 2 to 3 inches long, on short, slightly winged
petioles: heads (6 lines high) numerous, corymbose: involucral bracts short
and broad, the inner ones acutish, hirsute on the margins, rays small and
narrow, mostly shorter than the disk flowers: akenes 2 to 24 lines long,
broadly obovate, hirsute, with two long slender persistent awns, over 3
lines long. In cafions. .

Encelia Californica Nutt. Form, fide S. Watson. Very shrubby below, a com-
pact plant about 2 feet high. Grows in exposed places. Collected by Dr.
Streets in 1875, but only in flower. Dr. Pond has collected the same on the
south end of the island, which Mr. Greene considers /. conspersa, Benth,
Mr. Brandegee has recently collected at the original station (Magdalena Bay)
what he considers Benthaim’s plant. We have not seen his specimens, (87
of Mr. Greene. )

shrubs. (No. 46 of Mr. Greene.)

Amplyopappus pusillus H. & A. Not before reported from here, but appa-
rently common.

Porophyllum gracile Benth. Small and compact. Found at the mouth of a
cafion. Has the strong aroma of the cultivated rue. (No. 45 of Mr. Greene.)
Collected also by Lieutenant Pond this year.

Bebbia juncea Greene. Common in cafions (No. 39 of Mr. Greene. )

Senecio sylvaticus Linn. Only two small plants seen on mountain slope
near the base. Not before found on the island.

Senecio Cedrosensis Greene. Bull. Cal. Acad., I, 194. Rather compact
growing plant with small green leaves, and sulphur-colored flowers; a good
bloomer; grows in elevated places and canons. Not before found in flower ;
rays 8, small; akenes puberulent. (No. 47 of Mr. Greene.)

Trixis angustifolia D.C. Rather common. (No. 43 of Mr, Greene),

Rafinesquia Californica Nutt. Not common; in cations among other plants.
Not before found here.

Microseris linearifolia Gray. In cafions in shade of bushes.

Malacothrix Clevelandi Gray. Dr. Palmer reports this species common in
canons among rocks and bushes. Mr. Greene only found a few plants in
1885. (No. 50.)

Sonchus tenerrimus Linn. Shady side of cafions and under bushes. More
common than the next.

S. oleaceus Linn., in part. With the last.

Gilia Veatchii Parry. Bull. Cal. Acad., I, 198. Very common. Collected
by Dr. Veatch, in 1859, (No. 53 of Mr. Greene.) Dr. Palmer says flowers
‘¢ yellowish white ”.

The Cedros Island plant difters from Orcutt’s All Saints’ Bay plant of the.
Syn. Flora, and Palmer’s Coronados Island plant. The plant is smaller, less
viscid; the corolla smaller, less open, the style and stamens inelnded, the
capsule shorter than the calyx, the appendages large, somewhat reflexed,
Palmer’s Coronados Island plant grows along the beach under the influ-
ence of the sea water. And Mr. Oreutt writes that the same is true of his
plant.

715. Phacelia (Eutoca) Cedrosencis Rose n. sp. Very hispid with slender bris-

tles, also a little viscid in the inflorescence : stems 1 to 6 inches high, simple
or somewhat branched: leaves pinnate, the segments entire or few toothed,
inflorescence somewhat crowded, mostly geminate: flowers almost sessile :
calyx parted almost to the base, its lobes linear or oblanceolate, 3 lines long,
delicately three-nerved: corolla bluish, campanilate, about the length of
the sepals: stamens barely exserted ; appendages long and narrow, united to
the stamens at base: style cleft for one-thirdits length; capsule one and one-
half lines long, obtuse: seeds twelve to eighteen, Seemingly nearest P. hir-
tuosa of Lower California. Found in the shade of bushes in cations. Not
very common. A species peculiar in its dense bristles.

Krynitzkia maritima Greene. Stems very much branched,
The same with longer narrowly-lanceolate leaves, much resembling the A,

ramosissima of Palmer’s, Los Angeles Bay, 1887. Always one glabrous nutlet,
with oneor all the others maturing, but different, as described by us in a former
paper.

Pectocarya linearis D.C. A single specimen found under pines at the sum-

mit of the highest peak (1,761 feet), north end. New totheisland. The nut-
lets differ somewhat from most specimensseen, but much resemble P. linearis,
var. of Leminon (1884), Arizona.

Plagyobothrys Cooperi Gray. A few plants found on the highest point of

the island. The stipe to the nutlet, only about half as long as in our San
Quentin plant. New to the island.

Physalis Greenei. Only one small plant found. Thisis very close to Palmer’s

6382, from San Quentin, and the close resemblance of the latter to Dr. Streets’s
Cedros Island plant, we pointed out in our former paper, Proc. U. 8. Nat.
Mus., vol. XI,533. P. pedunculata Greene non Mart. et Gal. The San Quen-
tin plant Mr. Greene writes is his P. muriculata.

Lycium Cedrosencis Greene? A few sterile branches.
Nicotiana Greeneana Kose n. sp. Somewhat viscid, pubescent, 4 to 9 inches

high, simple or little branched at base: lower leaves oblong to lanceolate, 1 to
2 inches long, petioled: the upper ones linear: calyx lobes unequal, the longer
about the length of the tube: corolla yellowish white, 5 to 8 lines long, a lit-
tle constricted at the orifice, its limb 2 to 3 lines broad: the stamens equally
inserted low down in the tube: capsule four-valved, longer than the calyx
tube, ‘This species seems nearest N, Clevelandi in its leaves and calyx, but
the corolla is more like N. trigonophylla. It seems quite distinct from cither.
Not very common. Dr. Palmer says in his note respecting this plant, ‘“ All
the plants seen were taken; not very sticky, nor had the plants but a faint
odor like that accompanying the handling of tobacco.”

714. Antirrhinum Watsoni Vasey & Rose. A small form, 3 to 8 inches high with

linear leaves, “corolla purple.” Very rare. At the north end in the shade
of bushes in ravines. Not before collected on the island. Mr. Brandegee, in
his paper on the “Plants of Baja, California” gives two additional stations,
viz: Magdalena and Santa Margareta Islands. The species is doubtless com-
mon and of a wide range.

725. Antirrhinum subsessile Gray? Only three small plants found in the shade ;

2to 8 inches high. In fruit, no flowers. At least new to the island.

720. Galvesia juncea Gray. Collected by Dr. Streets in 1875 (No. 5e of Mr.
Greenc) ; Lieutenant Pond (1859). Grows in large bushes 5 feet high. Des-
cribed in Syn. llora as being only 2 feet high.

681. Mimulus cardinalis Dongl. Hort. ‘Trans. X1,70, Only a single specimen col-
lected. (No. 56 of Mr, Greene. )

739a. Pentstemon cedrosensis Kellogg. Proc. Cal, Acad. x1, 19. Collected by Dr.
Veatch in 1859, and the flowers deseribed as yellow. Mr. 8S, Belding obtained
it here in 1881, and Dr. Gray described it as P. brevilabris with a white (?)
corolla, In dried specimens the corollas have a yellow or deep orange color
Dr. Palmer’s field-note says, “bloom scarlet ; very showy,” very common in
canons near the ocean. (No. 55 of Mr. Greene’s list.)

728. Mimulus glutinosus Wendl. Only three plants seen; flowers only 1 ineh
long; ‘bloom amber color.” Mr. Greene thinks this plant is distinet from:
those of the mainland. Collected by Dr. Veatch in 1859. (No. 57 of Mr.
Greene. )

677. Verbena lilacina Greene. Bull. Cal. Acad., I, 212. Ravines; “rather showy
plant, abundant bloomer of a lilac color and very fragrant.” Collected first
by Mr. Greene, 1885. (No. 62.)

684. Salvia cedrosensis Greene. Bull. Cal. Acad., I, 212. Common plant on the isl-
and. <A mere fragment was collected by Dr. Veatch. (No. 61 of Greene.)
Only known to the island.

703. Eriogonum fasciculatum Benth. ide Watson. The same as 729 from San
Quentin, of former paper.

706. Eriogonum Pondii Greene. Pitt I, 267. Compact plant about a foot high in
exposed situations. (No. 85 of Mr. Greene’s list.) Collected by Lieutenant
Pond, 1889,

710. Pterostegia drymarioides Fich & Mey. Grows among bushes and rocks in
shade. It seems not to have been collected before on the island.

704. Harfordia fruticosa Greene, Parry in Proce. Acad. Davenp.,V., 28. This spe-
cies, before little known, has now been collected in great abundance, both in
flower and in fruit. The perianth is six parted and stamens nine in two rows,
The flowers seem to be perfect and not diecious. This is one of the most
common shrubsof the island, growing in cafions and exposed places; 3 feet
high. Collected by Dr, Veateh. (Mr. Greene’s No. 63.) Lieutenant Pond,
1889, |

737. Mirabilis Californica Gray. Collected by Dr. Streets in 1876. (No. 65 of Mr.
Greene, ) .

754. Atriplex. n. sp. Diecioys, perennial atfd woody at base, 1 to 2 feet long, erect
or ascending, glabrous and densely glaucous, becoming a little seurfy in age:
leaves small (6 to 12 lines long) broadly ovate to oblong, tapering at base
into a short petiole, abruptly acute at apex: bracts small (14 lines wide by 1
line high) somewhat, compressed, cuneate at base, scarcely marginal witha
few small teeth above, sometimes a little muricate on the sides: sterile flowers
densely glomerate, five parted. Grows in abundance near the beach. Per-

729. Simmondsia Californica Nutt. This is 8. fabulosa of Kellogg, referred here
by 8S. Watson, but without seeing specimens. It is only known from Dr.
Veatch’s collection and was not rediscovered by Mr. Greene. Dr. Palmer
speaks of it as a large shrub at mouth of cafions.

676. Juncus robustus Wat.

764. Juniperus Cerrosianus Kellogg. ‘An irregular shrub, 3 to 6 feet high, on
various parts of the north end, but of no particular use.”

points of the island, on the slopes of shady ravines, and under bushes.

660. Melicaimperfecta Trin. Found, not abundantly, upon hill-sides and ravines,
growing more thriftily near small shrubs and among rocks, as if seeking
shade or moisture.

what is known as the watering place of the island.

SAN BENITO ISLAND PLANTS.

Mr. E. L. Greene has very recently published (Pittonia, vol. 1, pp.
961-266) a very interesting little paper on the vegetation of the San
3enito Islands with a list of the known plants. He has enumerated
twenty-four species as belonging to the largest islet. His plants were
collected by Lieut. Charles I’. Pond at various times from December to
February. Dr. Edward Palmer spent but a day (March 25) on West
San Benito. His general notes of the island and its vegetation are very
similar to Mr. Greene’s, and need not be repeated here. He collected
seventeen species, all of which are given in Mr. Greene’s list. He has,
however, collected some of the varieties in considerable abundance.
He speaks, also, of two forms of Agave, neither in flower or fruit. No
specimens were sent in, and nothing is known as to the species. If
these should prove two distinct species, of course it will increase the
number of species to twenty-six. We have included for convenience
in a parenthesis, Mr. Greene’s number.
909. Eschscholtzia ramosa Greene. Bull. Torr. Club, xt, 217. This plant was

collected in 1876 on these islands by Dr. Streets. (No. 1 of Mr. Greene.)

908. Frankenia Palmeri Watson, Abundant, especially on level places; a foot to
18 inches high; flowers white to pink. (No, 4 of Mr. Greene.)

21

917. Lavatera venosa Watson. Proc. Aim. Acad., x11, 249. Poor specimens were
collected by Dr, Streets in 1875. Not since collected until obtained by Lieu-
tenant Pond. Dr. Palmer says of it: ‘The plant that leads in numbers all
others on the island, Its bright green gives the island rather a fertile look.
It is on all the level places in the arroyos and deepest canons and reaches to
the summit. A beantifnl plant with white and purple flowers, much darker
at night, 1 to 3 feet high. The petals are at first straight, and then turn
under as they take on the purple color. A fine plant for cultivation in green-
houses and gardens of warmer latitudes.” Dr. Palmer has collected it in
great abundance, and has obtained a good supply of seed. (No. 3 of Mr.
Greene, )

913. Hosackia maritima Nutt. Buta few specimens collected. The pods are three
to nine seceded, (No. 3 of Mr. Greene.)

922. Cotyledon linearis Greene. Pitt., 1, 285. Very common plant, in bunches
over the lower portion of the island. (No. 10 of Mr. Greene. )

921. Mammillaria Goodrichii Scheer.

Mesembryanthemum crystalinum L. Dr. Palmer says the ‘Ice plant” was very
plentifal on the island, but sent in no specimens, Mr. Greene has, however,
identified the species from this island. (No. 11 of Mr. Greene. )

920. Hemizonia Streetsii Gray, Collected quite abandantly, (No. 15 of Mr.
Greene.) First collected here by Dr. Streets.

915. Amblyopappus pusillus Hook & Arn. (No. 16 of Mr. Greene. )

914. Perityle Greenei Rose. Bot. Gaz., xv., 117. (No. 17 of Mr. Greene.)

911. Krynitzkia ambigua Gray. Growing on the side of a canon. The plant is
clearly the one collected by Licutenant Pond, but this, as well as Mr.
Greene’s type, has four nutlets. We have carefully compared both speci-
mens with a very full set in the Gray Herbarium, and we have not been able
to separate them. The nutlets are identical and there are specimens with
the same habit. (Cryptanthe patula Greene. ) (No. 21 of Mr. Greene.)

912. Krynitzkia maritima Greene. Only a few specimens were collected, as
nearly all the plants were dead. ‘The plants are found from 2 to 8 inches
high and much branched. Growing on rocky sides of a cafion. (No. 20 of
Mr. Greene.)

916. Gycium Californicum Nutt. (No. 19 of Mr. Greene.)

Mr. Greene. )

GUADALUPE ISLAND PLANTS,

Botanists generally will be delighted to know that Dr. Palmer has
again visited Guadalupe Island and brought back a large and inter-
esting collection. Only a week was spent on the island, from March
27 to April 3, 1889, but he succeeded in laying in a good supply of a
number of species only known from this island and sparingly repre-
sented in our herbaria. Besides these several new species were found.
He began his collecting at the south end of the island, where the last
three days of March were spent, and the first three days of April were
spent at the north end of the island.

It will be remembered that in 1875 Dr. Edward Palmer spent three
months (February to May) on this island. This was the first visit ever

22

made to Guadalupe Island by a botanist. The next year appeared
Mr. Watson’s admirable paper (Proc, Amer. Acad., vol. x1) on the
flora of this island and a list of Dr. Palmer’s plants, of which twenty-
one were considered new.

Ten years afterward Mr. E. L. Greene spent a week (the last of April)
adding to the flora fifteen species, describing seven new species, and
publishing in 1885 (Bull. Cal, Acad., vol. 1) his notes, and a catalogue
of the flowering plants and ferns of the island.

Mr. Watson separates the phienogamous plants into five groups as
follows: (1) Introduced species, twelve; (2) species which range from
the Pacific to the Atlantic States, nine; (3) those found in California
as far north as San Francisco, forty-nine ; (4) those only in southern Cali-
fornia, eighteen; (5) those peculiar to the island itself, twenty-one.
Add to these an undetermined Heuchera and six ferns makes a total of
one hundred and sixteen Phenogams and Pteridophyta. Mr. Greene’s
list enumerates one hundred and thirty species, all except twenty-six
he had observed in his short stay upon theisland. Probably six of the
fifteen added by Mr. Greene belong to the first group. Among the
present additions at least four have very recently gained a foot-holl
here, viz, Melilotus Indica, Sonchus tenerrimus, Suaeda Torreyana, and
Centaurea Melitensis, making the total number of introduced species as
twenty-two; one is to be added in the second group. In the third
group, Mr. Greene’s list adds five and ours three, viz, Tissa macro-
theca, Tissa pallida, and Trisetum barbatum, making the number of dis-
tinetly Californian species fifty-seven.

In the fourth group the two Cactacee and two Graminee make the num-
ber of southern Californian speciestwenty-two. Of the fifteen additional
species: added by Mr. Greene but one he described as new, another
probably new. Dr. Palmer has at this time collected seventy-two spe-
cies, fourteen of which are additions to the flora of the island and four
are new. The total number of species now known on the island is one
hundred and forty-five. Of the thirty-four species first described from
this island but three have since been found elsewhere. The following
list so far as known is peculiar to the island:

1. Eschscholtzia Palmeri Rose, 16. Perityle incana Gray.
2. Lavatera occidentalis Wat. 17. Baeria Palmeri Gray.
3. Spheralcea sulphurea Wat. 18. Arynitzkia foliosa Greene.

5. Lupinus niveus Wat. 20. Phacelia phyllomanica Gray.
6. Lupinus Guadalupensis Greene. 21. Phacelia floribunda Greene.
7. Trifolium Palmeri Wat. 22. Convolvulus occidentalis Gray.
8. Hosackia ornithopus Greene. 23. Convolvulus macrostcgia Greene,

island, and extends the range of the species considerably southward,

864a. Tissa pallida Greene. Bull. Torr. Club, vol. xvi, 129. Colleeted with the
preceding, but not so common. This species was described in the Torrey
Bulletin of 1880 (p. 129); has previously only been found nearSan Francisco

2 to 24 lines long. The upper margin is rather thick and broad and of
different texture. The carpels are narrower and longer than in S, sulphurea,
two ovules commonly maturing. Found in all exposed parts on the south end
of the island. This species seems quite distinct fram S. sulphurea.

861. Lupinus niveus Watson. Annual, 6 to 15 inches high; the ovate cotyledons
(6 to 8 lines long) persistent; leaflets oblanceolate, obtuse; pods 1 to 14 inches

24

859. Trifolium Palmeri Watson. Quite common on the south end in wet sand in
cations. (No. 26 of 1875

832. The same. Very common in large masses in cafions and plains at the north
end. This plant is widely distributed over the island, and forms the main
food supply for the goats.

831. Trifolium microcephalum Pursh. A very common plant at the north end in
cations and exposed places. It is much eaten by goats. April 1. (No. 27 of
1875.)

840. Melilotus Indica All. Not before reported from the island. Comunon along
the beach, ascending into shady cations and perhaps introduced with the
goats. North end of island. April 1 to 3.

853. Hosackia ornithopus Greene. Only one plant found near the mouth of a
canon at the north end. Mr. Greene found it abundant in the middle of the
island, 1885. We have not seen Palmer’s 1875 plant.

847. Vicia exigua Nutt. Common in shady sides of ravines at the north end. Dr.
Palmer on his first visit only saw a single small specimen. Mr. Greene says
it was not uncommon.

893. Mentzelia dispersa Watson. Common among shady rocks in cations. South
end of the island March 29. (No, 32 of 1875.)

850. Galium aparine L. At northend. April 1. (No. 35 of 1875.)

900. Tillzea leptopetala Benth.

902. Opuntia prolifera Engl. Grows on both ends of the island on stony ridges
and steep mountain sides. 3 to 5 feet high; notin flower. Collected by Mr.
Greene.

Mesembryanthemum crystallinum Linn. Dr. Palmer wrote that this grew on the
island, but collected no specimens. Mr. Grcene also collected it.

901. Mamillaria Goodridgeii Scheer. With five to six globose heads. At first cov-
ered with a white wool but becoming glabrate. Common on south end of
island. Not found by Dr. Palmer in 1875, but collected by Mr. Greene in 1885,

899. Amblyopappus pusillus H. & A. March 30, (No. 46 of 1875.

1875.)

885. Gnaphalium Sprengelii H. & A. Only three plants seen, these in the bed
of an arroyo. Southend. March 29. Collected by Palmer in 1875, but
without number.

874. Hemizonia(Hartmannia) Palmeri Rose,n.sp. Perennial, with thick woody base,
forming small bunches; branches decumbent or ascending, with abundant,
white, silky pubescence, not at all viscid: leaves numerous, silky, to 12 lines
long, linear to narrowly oblanceolate: heads numerous, somewhat corym-
bose: involucre 2 lines high: rays eight, three-tcothed: the chaff forming a
cup about the disk-flowers cleft to the middle, the divisions linear-acuminate :
disk flowers about ten, the akenes sterile: pappus of six to twelve, linear-
acuminate scales, the ray akenes barely a line long, the rostellum very short,
and compressed closely against the top of the akene.

A peculiar species, and by far the most decided shrub of the genus. In many
respects near to the following, but in leaves, pubescence, inflorescence, cte.,
very different. A very common plant on the south end of the island, in
all exposed places Dr. Palmer writes that it is a very attractive plant in that
dry latitude. The three species from this island seem to form a peculiar
group by themselves,

865. Hemizonia (Hartmannia) Greeneana Rose, n. sp. Perennial, forming large
round bunches 2 to 3 feet high, with sterile branches hanging down the sides,
somewhat pubescent, more or less viscid throughout: leaves crowded, dark

25

green; those of tho sterile branches lanceolate in outline, with a thiek
margin, 6 to 10 lines long, six to eight pinnately-toothed and parted, some-
times entire; those of the central flowering branches smaller, linear, entire:
Heads single, terminating the branches: involucro 3 lines high: rays 8, three-
toothed, the chaff forming a cup about the disk flowers, united until maturity,
with eight ovate, acute-tipped teeth: disk flowers eight to ten, sterile: pap-
pus of six to ten unequal paleaceous bracts, mostly shorter than the akene:
the ray akenes over a line long, the rostellum a half line long.

A very peculiar species, but seemingly nearest H. frutescens of this island. It

differs from that species strikingly in manner of growth, in its inflorescence,
in its leaves, and in its internal involucre. ‘The akenes are very similar but
larger. H. frutescens is a very rare species from near the central part of the
island. This species is very common on the south end in all the arroyos,
canons, and aleng the beach. It isa very homely plant, growing in great
clumps in barren places, and the most noticeable plant of the region.

BeriaPalmeriGray. First collected on this island by Palmer in 1875 and after-
wards by Greene. It is very common at bottom of cafons at south end of
island. March 29. (No. 45 of 1875.)

Franseria camphorata Greene. Bull. Cal. Acad.,i, 192. Very common on the
south end of the island. March 29. (No, 40 of 1875.)

Perityle Grayi. Rose, Bot. Gaz., xv., 118.

Microseris linearifolia Gray. At the north end. (No. 50 of 1875.)

Senecio Palmeri Gray. Dr. Palmer makes the following note with reference
to this plant: ‘Since my previous visit to this island this plant has de-
creased ; spots that contained a thicket of it have now but dead plants, with
a few scattering plants alive.” Professor Greene speaks of this plant as being
quite common, The rapid extermination of this species seems to be a parallel
case tothat of Cupressus Guadalupensis, spoken of by Mr. Greene. (Proc. Cal.
Acad., I, 217.) Fortunately Dr. Palmer has laid in a supply of this species,
and all our American herbaria will have good specimens, even if if should
become extinct. (No. 45 of 1875.)

Centauria Melitensis Linn. This weed has become introduced on the north
end, and is gradually finding its way up the island. Not reported in the
other lists from the island.

Sonchus oleraceus Linn. Small, slender form, from2 inches to a foot high;
radical and lower cauline leaves mostly undivided. Shady spots in cations ;
not very common, At the south end. (No. 52 of 1875.)

The same, but somewhat taller, with pinnate leaves, the lobes spinulose-toothed.
Also in cafions at the south end, but rarer.

Sonchus tenerrimus Linn. A very small, slender form 2 to 8 inches high,
Growing in shady canons at the south end. An introduced species. Not
before found on the island. Not common.

Gilia Nevinii Gray. Only a half dozen plants seen on south end of island.
When first collected in 1876 it was found very abundant. March 30, 1889,
(No. 78 of 1875.)

The same, A few plants found at the north end. April 1.

Nemophila racemosa Nuit. Have seen no specimens of this species, The
Guadalupe plants of Palmer, 1875 (No. 76), were referred to N. aurita. The
linear segments of the leaves are strongly serrate. Tho flowers minute,
apparently smaller than the species. Among rocks, edge of dry arroyo. Mareh
30, south end of island.

The same, from the north end, where it is more common, and found among
rocks in cafions.

26

835. Ellisia chrysanthemifolia Benth. The stems are prostrate or ascending,
divaricate, very pubescent. Leaves mostly opposite, pinnate ; the oval lobes
toothed ; calyx very small, shorter than the capsule. Corolla white, about
the size of calyx. Only found in caiion at north end. April 1. (74 and 75
of 1875.)

866. Phacelia floribunda Greene. Bull. Cal. Acad.,i, 200. In shady cafion at the
south end. '

866a. A small, almost simple form, 3 to 5 inches high, growing with the last.

833. The same, from cafions at the north end. In all these cases the capsule is
somewhat oblique, and only a single seed matures.

848. Emmenanthe penduliflora Benth. Found in canons and hill-sides, at both
ends of the island. April 1. On the north end, ;

898. The same, from the south end of island. March 30. (No. 73 of 1875.)

894. Krynitzkia foliosa Greene. Certainly very distinct from MK. ambigua. Only
known from this island, but here common, growing with I’. maritima. First
collected by Palmer (No. 68 of 1875) and afterwards by Greene. Found in
sandy arroyos and shady cafions. March 29 and 30. South end of the island.
No, 877 the same,

842. The same, from a cafion at the north end.

879. K. maritima Greene. A small compact form, growing with No, 877 (No. 67
of 1876) on south end of island.

860. Solanum nigrum Linn. var. About a foot high, glabrous; leaves dentate,
small; flowers small (about two lines in diameter), violet. Only a single
plant found growing among rocks in cation, on south end of island. March
29, (No. 60 of 1875.)

839. Mimilus latifolius Gray. (No. 58 of 1875.)

878. Plantago Patagonica Jacq. South end of island; common. March 29. (No.
D4 of 1875.)

888. Pterostegia drymarioides I’. & M. (No. 84 of 1875.) At sonth end. March
30.

843. Tho same. Found in cafons among shady rocks at north end, April 1.

886, Mirabilis Californica Gray. Common. (No. 82 of 1875.) South end of island.
March 30.

884. Parietaria debilis I’oster. Common in shady cafions. (No. 87 of 1875.)

658. Brodiza capitata Benth. In deep ravines and on hill-sides on the south end
of the island. Not reported in Mr. Watson’s paper, but Dr. Palmer says it is
now quite plentiful, Also found by Mr. Greene.

857. Polypodium Californicum Kaulf. On the north end. (No. 103 of 1875.)

855. Notholzna Newberryi Eaton. (No. 103 of 1875.)

856. Gymnogramme triangulare Kant.

656. Muhlenbergia debilis Trin. Found in the shade of rocky ledges and also in
the exposed part of a cafion of the southern part of the island.

670. The same; collected at the northern end of the island. Goats do not eat this
vrass.

657. Festuca tenella Willd. Habitat as 656. Saw no indications of the feeding
of goats (the only animals here) upon this grass.

674. The same; found the south of the island.

658. Trisetum barbatum Steud, Evidently an annual; beyond the frost line it
may be perennial. In dry seasons very little seed is formed, as the goats
crop this plant closely (there is but scanty vegetation on this, the southern
end of the island), but this year rain has been frequent, and this plant is
abundant, enabling us to get ripe seed. This may be improved by cultiva-
tion, plants found in favorable situations becoming quite large. It also
makes good hay.

27

667. The same; from northern part of island. Very common grass, making the best
forage upon this end of the island. In the caions it is very large, growing
so thickly that it looks like grain.

673. The same.

668. Avena barbata L. Found some specimens 4 feet high in the cafions and on the
rough slopes.

669. Aristida bromoides H. B. K. In deep caiions wnong other grasses and plants.

675. The same.

671. Hordeum murinum L. Very abundant, bidding fair to exterminate other
grasses and plants.

672. Festuca Myurus L. Not common. Grows in bunches in cations among
other grasses.

MEAD OF THE GULF OF CALIFORNIA,

Three days were spent at Lerdo, Mexico. This locality is 60 miles
south-southwest from Yuma, latitude 31° 46/ 10”, and longitude 1142
43/ 30”,

The most interesting thing obtained here was Ammobroma, which for
the first time has been collected in good quantity.

956. Nasturtium palustre D.C.

955. Achyronichia Cooperi T. & G. Places in river bottoms. Lerdo, Mexico.

934. Dalea Emoryi Gray. In the deserts of southeast California and western
Arizona, and south to Los Angeles Bay. One of the two hosts of Ammo-
broma.

941. Ginothera scapoidea Nutt. Var. Stems 4 to 8 inches high, much branched at
base, lateral leaflets very small, or none; calyx dark red within, petals less
than 2 lines long, light yellow. Hemsley does not mention this plant as
growing in Mexico in Biol. Cent. Amer.

933. Franseria dumosa Gray. Also collected here by Dr. Edward Palmer in
1885. This species is common in the desert regions of south Utah, Arizona,
southeast California, and extending as far south as Los Angeles Bay, Lower’
California. This is one of the two species upon which Ammobroma Sonora is
found, and its wide distribution leads us to expect that other stations of that
parasite will yet be found,

957. Gnaphalium Sprengelii H.& A. Dry places in river-bottoms.

940. Palafoxia linearis Lag. On the dry sand-hills.

Ammobroma Sonore Torr. This was first discovered in 1854 by Col, A. B. Gray,
in charge of a railroad exploring party, at the head of the Gulf of Califor-
nia. At this time ashort notice of the discovery was published by Col. A.
B. Gray in Memoirs of the American Academy of Science, but it was not
until 1567 that a description of the genus was published by Dr. John Torrey
in the Annals of Lyc. Nat. Hist. N. Y. Vol. VII, p. 51, together with a good
figure. So far as we can learn the plant was not collected again until
Schuchard got it im Arizona, And now Dr. Palmer collected it in large
quantities at Lerdo, Mexico. Until the present season its host plant has
been unknown but Dr. Palmer has carefully examined into this, and col-
lected twocemmon plants of this arid region upou which it grows. Theseare
Fransevia dumosa and Dalea Emoryi. Dr. Palmer wrote that the plant grows
in deep sand, the deeper the sand the larger and juicier the plants. The
Cocopa Indians gather them for food, which they relish under all circum-
stances. They cat it raw, boiled, or roasted. The plant is full of moisture,
and whites and Indians alike resort to it in traveling, as a valuable
substitute for water. It has a pleasant taste, much resembling the sweet

28

potato. ‘Tho'stems are 24 feet long and 1 to 4 inches indiameter, but almust
buried, only the peculiar white tops appearing above the sand. The Cocopa
Indians call it ‘‘Oyutch.” Colonel Gray gave much the same report of this
plant. He says the Papago Indians dry the stems and grind them with the
mesquit beans, forming, what they call ‘ pinole.” .

937. Aphyllon Cooperi Gray. Parasitic on Franseria dumosa, The Cocopa In-
dians also use this plant for food. It is very bitter, but this is mostly re-
moved by boiling. ‘They call it ‘‘nep-cha-ga.” It grows in the sand.

938. This isthe same. Parasitic on Ephedra.

953. Amaranthus Palmeri Wat. Var. <A peculiar cwspitose form, forming great
mats, some stems with slender ascending or erect stems 4 to 10 inches long.
At Lerdo, Sonora, Mexico, April.24 to 26, 1889. Grows in river-bottom, in
rather dry places.

958. Probably the sterile of the same. Stems much branched at base and slender,

Sagittaria variabilis Engl. The bulbs of this plant are much used by the Cocopa
Indians either raw or roasted. Lerdo, Sonora.

Ruppia maritima, Linn. Lerdo, Sonora. Hemsley says that this species had not
been collected in Mexico, although it might be expected.

931, Scirpus maritimus, Linn. fide ¥F. V. Coville.

924-931. Uniola Palmeri Vasey. This grass was collected 35 miles south of Lerdo
and about 15 miles from the mouth of the Colorado River. It grows abun-
dantly on the tidal lands and forms almost the principal food-plant of the
Cocopa Indians. A full account of this plant, with plate, appears in the
Garden and Forest for August, 1889.

948. Panicum colonum Linn. An apnual grass of which the seeds are used for
food by the Indians.

947. Panicum capillare Linn. var. miliaceum, V. A peculiar variety with a
drooping panicle, of the habit of P. miliaceum but with smaller spikelets.
This is also used as food by the Indians, who sow the seeds in the rainy
season.

946. Lolium temulentum Linn. Introduced.

945. Diplachne imbricata Scrib. This extends into Arizona and southern Cali-
fornia.

UPON A COLLECTION OF PLANTS MADE BY MR, G.C, NEALLEY, IN THE
REGION OF THE RIO GRANDE, IN TEXAS, FROM BRAZOS SANTIAGO
TO EL PASO COUNTY,

By JOHN M. COULTER.

Mr. G. C, Nealley was engaged by the Division of Botany to make
collections of plants during the seasons of 1887, 1888, and 1889, in the
more unexplored parts of Texas, chiefly in the counties bordering the
Rio Grande. It was hoped that many of the rarer plants of the Mex-
ican Boundary Survey and other early collections would be re-discov-
ered, that additional Mexican types would be found to be members of
our flora, and that species new to science would be brought to light.
How far these hopes have been realized is shown in the following re-
port. Itis to be regretted that in many cases the stations are no more
definitely given, but they are given with all the fullness that the field-
notes will justify.!

1. Clematis crispa L. Near Brazos Santiago in April, and later at Ballinger
(Runnels county).

2. Clematis Drummondii Torr. & Gray. In great abundance along the Rio
Grande near Roma (Starr county).

3. Clematis Pitcheri Torr. & Gray. Concho county.

. Aquilegia chrysantha Gray. Southwestern Texas.

. Cocculus diversifolius DU. (C. oblongifolius DU.) Southwestern Texas. - Two
forms of this species occur in Mr, Nealley’s collections; one with ovate leaves,
the other with narrowly oblong leaves.

6. Castalia elegans Greene (Nymphea elegans Hook.). Along the lower Rio Grande

near Santa Maria (Cameron county), and apparently in considerable abun-

dance. This rare and beautiful species, remarkable on account of its light
blue petals, was discovered by Charles Wright in 1849, ‘‘near the head of
the Leona River,” a Texan tributary of the Rio Grande. Grown from seed

at Kew, it was described and figured by Hooker in Curt. Bot. Maqg., t. 4604,

Afterwards a single specimen was found by Berlandier in northern Mexico,

and other specimens by Charles Wright in Cuba. For many years it was

unreported, when it was re-discovered in 1887 at Waco, McLennan county,
by Misses Trimble and Wright (reported by E. E. Stern in Bull. Torr. Bot.

Club, xv, 13); and in 1888 by C. G. Pringle, ir lagoons near Brownsville.

Bourgeau 4, from Santa Anita, Mexico, referred in Hemsl. Biol. Centr. Amer.,

i. 25, to this species, is probably Castalia flava Greene.

county). To this must be referred Bourgeau 4, from Santa Anita, Mexico, as
noted under the preceding species. The discovery of this Florida yellow
water-lily along the Rio Grande in Texas, as well as in Mexico, is an inter-
esting one. In Pringle’s distribution of 1888, no. 1956, from lagoons near
Brownsville, is labeled Nymphwa Mexicana Zuce., and it is undoubtedly the
same as our specimens from Mr. Nealley. There seems to be so much uncer-
tainty, however, as tu what NV. Mexicana is, and our plants so closely accord
with the well-known Castalia flava, that we have ventured to so name them.
It is but fair to say that none of the Nealley specimens are in fruit, and it
may be discovered that all of these Texano-Mexican yellow water-lilies
are Castalia Mexicana,

Nelumbo lutea Pers. (Nelumbium luteum Willd.) Along the lower Rio Grande,
near Santa Maria (Cameron county).

Argemone platyceras Link & Otto, var. rosea Coulter x. var. Petals bright
rose-purple. Corpus Christi. This includes also the form referred to by
Watson? Proc. Am. Acad., xvii. 318) under Palmer 20.

Thelypodium linearifolium Watson. Limpia cafion (Presidio county).

Thelypodium micranthum Watson, Limpia canon and Chenate Mountains
(Presidio county), Mr. Nealley’s plants are quite small and sometimes
simple, some of them being not more than 9 inches or 1 foot high. They are
sometimes also quite glabrous, even as to the lower leaves, and the stigma
seems sessile. This species is confused in herbaria with 7. longifolium Wat-
son, in which the flowers are twice as large.

Thelypodium Vaseyi Coulter, . sp. Glaucous and glabrous throughout, 6 to
9im high, branching, with coarse stems : leaves thin, oblanceolate, becoming
narrower above, entire or lower leaves somewhat repand-denticulate, clasp-
ing by rounded auricles (or the lowest merely sessile), 2.5 to 10°™ long,
1.25 to 3.75°™ broad: flowers very small, white, about 3™™ high: pods very
slender, becoming distant and ascending or erect, 3.75 to 5°™ long, on pedi-
cels 6 to 8™™ long.—Near Rio Grande City, Texas (Nealley); also collected
in 1881 by G. R. Vasey (no. 29) in the mountains west of Las Vegas, New
Mexico, in immature condition. Vasey’s plants were too young to be char-
acterized, although Mr. Watson, to whom the specimens were submitted,
considered them as probably representing a new species. Mr. Nealley’s speci-
mens supply nearly mature pods, which may become longer than noted in
the description. The species seems tu be very distinct from any other Thely-
podium.

Thelypodium Wrightii Gray. Limpia cafion (Presidio county), Specimens
in fine fruiting condition show pods mostly 3 inches long or over.

Lesquerella argyrea Watson (Vesicaria argyrea Gray). Roma (Starr county)
and Chenate Mountains (Presidio county).

Lesquerella Engelmanni Watson ( Vesicaria Engelmanni Gray). Camp Char-
lotte (Ixion county). The collection includes two forms: one leafy, with
very narrow and entire leaves; the other with nearly all the leaves rather
broad and sinuate-dentate.

Lesquerella gracilis Watson ( Vesicaria gracilis Hook.). Brazos Santiago.

Sisymbrium canescens Nutt. Limpia cafion (Presidio county ).

Sisymbrium diffusum Gray. Limpia cafion (Presidio county) and Chisos
Mountains (Foley county). This species was collected by Wright and the
Mexican Boundary Survey in the southwest corner of Texas. G. R. Vasey
and Rusby have collected it in adjoining New Mexico, and Pringle in Mexico.
Mr. Nealley’s Limpia caiion specimens were collected at Wright’s original
station.

Erysimum asperum DC. Limpia cafion (Presidio county).

20. Greggia camporum Gray. Chenate Mountains (Presidio county). This species
is remarkably variable, a fact which is better known in herbaria than in pub-
lication. Very little seems to have been added to Gray’s original description
in Pl, Wright., i. 8, but the immaturity of his specimens prevented him from
discovering certain characters which seem generic. No mention is made of
the fact, nor does it appear in the plate in Pl. Wright., that the mature
stamens are strongly sagittate and coiled, as in Thelypodium. The pod, in-
stead of being short and allied to that of Synthlipsis, is a silique (a fact
recognized by Bentham & Hooker), often quite elongated (an inch or more),
and usually more or less curved at maturity. In fact, the persistent septum
is always curved, often strongly so. The sepals also become strongly re-
flexed, The species G. camporum presents such great variations in the size
and shape of its leaves that extreme forms are never recognized by a collector
as forms of the same species. These specimens from the Chenate Mountains
have broad and sinuate-dentate leaves, the leaves being sometimes an inch
broad and so deeply sinuate-dentate as to appear almost pinnatifid.

21. Greggia camporum Gray, var. angustifolia Coulter, ». var. Leaves mostly
entire (occasionally sinuate-toothed) and very narrow (but 2 to 4™™ broad ).—
Camp Charlotte (Ixion county). If certain intermediate forms were not
common this variety would represent a fairly good species. The pods are
also quite variable in length in the same specimen. Considering the great
variability of the leaves and pods the following may be but another variety
of this polymorphous species:

22. Greggia linearifolia Watson. Camp Charlotte (Ixion county), mixed with the
last, to which it is closely related.

23. Lepidium alyssoides Gray. Camp Charlotte (Ixion county).

24. Synthlipsis Berlandieri Gray, var. hispida Watson. Brazos Santiago,

25. Cakile maritima Scop., var. zequalis Chapman. Brazos Santiago. A West
Indian and Floridian species found along the Texan coast.

26. Polanisia trachysperma Torr. & Gray. Corpus Christi. Ballinger (Runnels
county) and Limpia canon (Presidio county).

27. Ionidium polygalefolium Vent. Roma (Starr county).

28. Polygala alba Nutt. Brazos Santiago and Chenate Mountains (Presidio
county).

29. Polygala ovalifolia DC. Western Texas.

30. Polygala puberula Gray. Santa Anna (Coleman county),

31. Silene laciniata Cav., var. Greggii Watson. Limpia cafion (Presidio county).

32. Stellaria prostrata Baldw. Santa Maria (Cameron county) and Chenate
Mountains (Presidio county). The Chenate specimens are much smaller
than usual.

33. Talinum parviflorum Nutt. Corpus Christi.

33a. Talinum lineare HBK. (7. aurantiacum Engelm.) Corpus Christi.

34. Malva borealis Wallm. Brazos Santiago, An Old World plant, apparently
naturalized throughout our southern border from the Gulf coast of Texas to
California.

35. Callirrhoe lineariloba Gray. Pena (Duval county).

36. Malvastrum coccineum Gray. Rio Grande City (Starr county).

37. Malvastrum spicatum Gray. Brazos Santiago. A Mexican species,

38. Malvastrum tricuspidatum Gray. Brazos Santiago. Specimens smaller in
all dimensions than usual.

39. Malvastrum Wrightii Gray. Corpus Christi. A very small form, with un-
usually reduced bractlets.

40. Anoda hastata Cav. “Screw Bean” (Presidio county).

#1. Anoda pentaschista Gray. Chenate Mountains (Presidio county). The lower
leaves are rather larger than usual, some of them being broadly triangular

and 2 inches long by 14 inches wide. The variation in the leaves passing up
the stem is remarkable. In addition to the broad triangular leaves, some
are 3-lobed, then above become narrower and hastate, finally narrowing to
linear, but always hastate,

Sida lepidota Gray. Chenate Mountains (Presidio county).
Sida longipes Gray. Pena (Duval county). This seems to be the first recorded

collection of this species since Wright’s in 1851 and that of the Mexican
Boundary Survey. It very closely resembles S. Lindheimert Eng. & Gray,
but the muticous carpels, as well as the elongated fruiting pedicels, serve
well to distinguish it.

Sida physocalyx Gray. Pena (Duval county).
Abutilon Berlandieri Gray. Corpus Christi (Nueces county) and San Diego

(Duval county); also found in 1882 by G. W. Letterman at Laredo (Webb
county) and distributed as A. holosericeum Scheele, A Mexican species, Ber-
landier’s 1550, 3050, and 3108, from northeast Mexico, being the same.

Abutilon crispum Gray. Rio Grande City (Starr county).
Abutilon holosericeum Scheele. Santa Maria (Cameron county).
Abutilon incanum Don. (4. Terense Torr. & Gray). Rio Grande City (Starr

county). A. ineanum is a species of the Sandwich Islands, but considered by
Dr. Gray (Proc. Am. Acad., xxii. 301) identical with our 4. Texcense, “not-
withstanding the disjointed range.”

Abutilon Nealleyi Coulter, x, sp. Stem slender, erect, 6 to 126 high, soft

puberulent above, becoming glabrous below: leaves broadly cordate and long
acuminate, entire or slightly crenate, green and soft puberulent (becoming
glabrous) above, white with fine dense stellate pubescence beneath, 6 to 10™
long, § to 7.5™ wide, becoming smaller above, on long petioles (2.5 to 9m
long), the lower with axillary fascicles of small leaves: flowers in loose, few-
flowered, long peduncled, npper-axillary and terminal panicles, very small,
not more than 4™™ high: calyx stellate-pubescent, deeply cleft, the ovate
acute lobes about half as long as the petals and very much shorter than the
carpels: petals yellow or orange, hardly 4™™ long: carpels 5, becoming 6 to
émm Jong, puberulent, with a short acuminate beak, 2 or 3-seeded; seeds
usually with a tuft of white hairs.—Near Hidalgo (Hidalgo county). This
species is an addition to the group of herbaceous, large-leaved, rather naked
paniculate and small-flowered forms, represented heretofore by A, Sonora
Gray, 4. reventum Watson, and A. Xanti Gray. A. Nealleyi has much the
smallest flowers, and looks somewhat like a species of Bastardia, but the 2 or
3-seeded carpels are plainly those of dbutilon.

Abutilon parvulum Gray. Near Pena (Duval county) and in the Chenate

Mountains (Presidio county).

county).

Spheralcea Fendleri Gray. Chenate Mountains (Presidio county).
Spheralcea subhastata Coulter, n. sp. Low (7 to 22™), fruticose and branch-

ing, covered throughout with coarse almost seurfy stellate-pubescence: leaves
thick, ovate to oblong, mostly obtuse and subhastate, rugose and more or less
serrate, 1.25 to 3.75" long, 10 to 16™™" broad, on thick petioles 6 to 16™™ long:
flowers mostly solitary and axillary on very short pedicels: calyx cleft about
half way, the lobes acute or somewhat acuminate, little more than half as

long as the purplish (in dried specimens) corolla, which is 1.25 to 2.5¢™ in
diameter: frnit subglobose, densely stellate-pubescent, with no apparent
cusps.—** Screw Bean” (Presidio county). To this species is referred Wright
e385 in part, collected in New Mexico in 1851; also Palmer 93, from Coahuila,
Mexico, collected in 1880, The species is intermediate between S. hastulata
Gray and 8, angustifolia, var. cuspidata Gray. Palmer 93 was considered by
Mr. Watson (Proc. Am. Acad., xvii. 331) to be a form of S. hastulata. Mature
fruit, as well as the coarse stellate-pubescence, indicates a much closer rela-
tionship to S. angustifolia, var. cuspidata, under which polymorphous species
it should be included if not entitled to specitie rank. It differs, however,
from that species in its low habit, short ovate or oblong subhastate leaves,
solitary short-pediceled flowers, and its pointless carpels,

Chisos Mountains (Foley county). In Bot. Calif.i. 136, Dr. Watson suggests
that H. puberula Benth. and H. Wrightii Gray are but forms of H, rigida
Benth. Botanists will testify to the impossibility sometimes of distinguishing
these species. In Nealley’s collection there are some remarkable specimens
that combine in one plant all the important characters of these three so-called
species. Some of the peduncles are short, and others very long ; the calyx-
teeth equal the tube or are shorter ; the leaves are from obovate or oblong to
narrowly linear. These specimens should be referred to H. puberula if the old
specific distinctions are to be kept up. After examining a large series of
specimens, however, it seems best to consider them all but as forms of a
wide-spread and very polymorphus species, of which H. Bryanti Brandegee
(Pl. Baja Calif. 144) seems to be but another form.

. Psoralea linearifolia Torr. & Gray, var. robusta Coulter, n. var, Whole
plant, in all its parts, more robust than the type: leaves linear-oblong, 4 to
6™ long, 5 or 6™ wide, thickly black-dotted above and below: flowers
mostly in clusters of three, distant along the rhachis.—Clarendon (Donley
county). Collected by Nealley in 1888.

Dalea alopecuroides Willd. Limpia caiion (Presidio county).

Dalea aurea Nutt. Santa Anna (Coleman county).

Dalea Domingensis DC., var. paucifolia Coulter, x. var. Whole plant more
hairy: leaflets but three or four pairs and larger: inflorescence becom-
ing more or less compact-clustered in the upper axils, and the calyx-tube
nearly glabrous, making very prominent the large amber-colored glands.—
Rio Grande City (Starr county). This is also Palmer 1049, collected in
northern Mexico between San Luis Potosi and Tampico, and referred by
Hemsley to D, Domingensis DC. The species has been found in 8. Florida,
and Mr. Hemsley (Biol. Central Amer., i. 239) credits it to Texas and New
Mexico, but from what collectors we are not aware. Mr. Nealley’s collection
brings the first Texan specimens we have seen.

Dalea formosa Torr. Chenate Mountains (Presidio county).

Dalea frutescens Gray. Devil’s River (Val Verde county), and Chenate
Mountains (Presidio county).

Dalea mollis Benth. Chisos Mountains (Foley county).

Dalea nana Torr. Roma (Starr county).

broad bracts.

Petalostemon emarginatus Torr. & Gray. Pena (Duval county).

Petalostemon multiflorus Nutt. Corpus Christi.

Petalostemon violaceus Michx., var. tenuis Coulter, n. var. A slender low
form rarely as much as a foot high, with round or roundish-oblong small
often few-flowered heads on long slender peduncles, and shorter pointed
bracts (not equaling the calyx, and hence not very apparent in the head).—
Santa Anna (Coleman county). Apparently the form referred to in Pl, Fendl.

variety is so distinct in character that it seems to deserve a name and descrip-
tion.

the first record of this Mexican species occurring in the United States. It
is quite variable in its pubescence, as well as its leaves. Our specimens are
all 3-foliolate, and hence seem not to be the same as D. annuum Gray (described
from Wright’s Sonoran specimens), which Grisebach has included under D.
spirale DC. However, they are clearly the same as the Mexican D. spirale
of Pringle, no, 612, and of Parry J+ Palmer, no. 181, and accord well with all
published descriptions.

Desmodium Wrightii Gray. Chenate Mountains (Presidio county).

Vicia Ludoviciana Nutt. Point Isabel.

Galactia heterophylla Gray. Pena (Duval county) and Chenate Mountains
(Presidio county). This remarkable species was first collected by Lind-
heimer. Nealley’s collection brings excellent specimens from both Pena in
eastern Texas, and the Chenate Mountains of western Texas.

Cologania longifolia Gray. Chenate Mountains (Presidio county).

Phaseolus acutifolius Gray. Limpia caiion ‘Presidio county). This species
has heretofore been collected only in Arizona, New Mexico, and Mexico, Our
specimens represent the large-leaved Mexican form.

Phaseolus umbellatus Britton. (P. helvolus of Am. authors, not of L.) Cor-
pus Christi.

Phaseolus macropoides Gray. Chenate Mountains (Presidio county). So
far as the United States is concerned this species has only been found in
New Mexico by Wright, in 1851; by the Mexican Boundary Survey; and
lately (1881) by Rusby in the Mogollon Mountains. Mr. Nealley’s discovery
of it in extreme western Texas not only brings us more of a rare plant, but
considerably extends its range. Pringle 1233 (1887), from plains near
Guerrero, Chihuahua, referred to P, heterophyllus Willd., also seems to be this
species,

Rhynchosia menispermoidea DC. Corpus Christi.

Rhynchosia Texana Torr. & Gray. Corpus Christi.

Hoffmanseggia Jamesii Torr. & Gray. Pena (Duval county).

Hoffmanseggia melanosticta Gray. Chisos Mountains (Foley county). So
far as I know, this species has been reported but once from the United States
side of the Rio Grande, and then by Parry, in the valley of the Rio Grande
below Donna Ana, in the Mexican Boundary Survey. ]t was found originally,
and but once since, in northern Mexico (by EHdwards at Rinconada and
Monterey, and by Gregg near Buena Vista and in a valley near Azufrora), and
is altogether one of the rarest of species. This Chisos Mountain collection
contains quite an amount of fruiting and flowering material. The speci-
mens conform exactly to the original description, In the case of the Mexican
Boundary Survey specimens Dr. Torrey speaks of the plants differing some-
what from the description of Schauer in having only two or three pairs of
leaflets, and the vexillum destitute of glands and dots. In the Nealley
specimens the leaflets are three and four pairs (mostly the former), and the
vexillum is decidedly dotted; the single specimen of Parry that we have
seen shows the same characters. This species is the only American represent-
ative of the section Melanosticta, the two other species being South African.
The section is characterized chiefly by the densely black-glandular calyx-
lobes. The species somewhat resembles our common H. Jamesii Torr. &
Gray, but the leaflets are fewer, larger, and more distant, the whole plant
more villous, and the legumes larger and much more muricate and glan-
dular. As no description of the species has been published in English, and
the Latin description is not very accessible, I append a translation of the
description given in Walp. Aun, i. 257: ‘‘Fruticose: branchlets and racemes

canescent with short villous retrorse hairs: leaves with two pairs of pinnz
and a terminal pinna; pinne all abrupt, with a mucronate rbachis; leaflets
three or four pairs, obliquely elliptical, very short petiolulate, very obtuse
or retuse, together with the rhachis loosely villous, black-punctate beneath,
as are the calyx and legume: racemes terminal or lateral, peduncled, loose-
flowered: legume two to three-seeded, muriculate, the short muriculations
stellate-pilose at apex.”

Hoffmanseggia oxycarpa Benth. Western Texas, collected in 1888. This
seems to be a very rare species, having been reported only by Wright from
Texas in 1851, and by the botanists of the Mex. Bound. Surv. from extreme
western Texas.

Hoffmanseggia stricta Benth. Corpus Christi (Nueces county) and Chenate
Mountains (Presidio county).

Parkinsonia aculeata L. Hidalgo (Hidalgo county).

Parkinsonia Torreyana Watson. Hidalgo (Hidalgo county). The finding of
this species along the lower Rio Grande was unexpected, as it has heretofore
seemed restricted to southern and western Arizona and contiguous Califor-
nia. Its representative in the Rio Grande Valley is P. florida Watson, and
they were thought to be as distinct in range as in characters, although the
western type was for a time confused with that of the RioGrande. Nealley’s
Specimens, however, collected in both flower and fruit, show the character-
istic inflorescence, the thick-edged pod with its double groove, and the leat-
lets of P. Torreyana, It is possible that the two forms should not be con-
sidered distinct species.

Cassia bauhinioides Gray. Roma (Starr county).

Cassia nictitans L. Chenate Mountains (Presidio county).

Cassia procumbens L. Pena (Duval county). This is a variable tropical-
American species, first found in Texas by Berlandier (no, 2427), and after-
ward by the Mex. Bound. Surv. Berlandier's specimen is larger than the
type. Nealley’s specimens conform better in size, but have the decidedly
larger stipules and flowers of the Berlandier specimen. In a species so
widely extended and variable such variation counts for little.

Cassia pumilio Gray. Chenate Mountains (Presidio county).

Desmanthus depressus Humb. & Bonpi. Sante Maria (Cameron county),
This speciesis abundant enough in southern Florida and the West Indies, also
from northern Mexico southward, but has only occasionally been collected in
Texas. The present collection indicates that it grows in abundance in Cam-
eron county, the most southern coast county of Texas.

Desmanthus reticulatus Benth. Corpus Christi (Nueces county) and Pena
(Duval county).

Mimosa Berlandieri Gray. Brazos Santiago. This rare species seems to
have been collected heretofore only by Schott, along the lower Rio Grande
in Texas, and by. Berlandier (no. 3146) near Matamoras, on the Mexican side
of the river. Both of these discoveries were reported in Bot. Mex. Bound.
Survey (1859). Nealley’s station, from which he has brought conside-
rable material, is just north of the mouth of the Rio Grande.

Mimosa biuncifera Benth. Southwestern Texas. Collected in 1887,

Mimosa dysocarpa Benth. Limpia eafion (Presidio county). This species
was collected by Chas. Wright in his New Mexican collection of 1851, and by
Emory in the Mexican Beundary Survey. Since then, it was collected in
1874 in Arizona by Rothrock, and by Pringle in his Chihuahua collections.
With the present collection in western Texas we have the range of this

Leucena retusa Benth. Limpia cation (Presidio county). This species was
collected by Wright (no. 171) in western Texas in 1549, and in New Mexico
(no. 1046) in 185t; then by the Mexican Boundary Survey (no. 318) in the
valley of the Rio Grande below Donna Ana; most recently by Reverchon
(no, 1262) on rocky bluffs near Junction City (Kimble county).

Acacia amentacea DC. Roma (Starr county). This collection brings to
hand, for the first time, the mature legumes of this species, at least Ben-
tham, in his Rev. Mimosew, says “ legumen ignotum,” and I find no record of
any subsequent discovery. The legume is short-stipitate, arcuate, 7.5 to
10. Jong, and but 4 to6™™, wide. It thus differs from its congener, 4. flexi-
caulis, in its stipitate and very narrow legume, as well as in its leaves with a
single pair of pinnie.

Acacia Berlandieri Benth. Hidalgo (Hidalgo county). Apparen tly quite
common on the dry hills of the lower Rio Grande.

Acacia constricta Benth. Roma (Starr county.) An abundance of fine fruit-
ing specimens.

Acacia Farnesiana Willd. Hidalgo) Hidalgo county) and Roma (Starr
county).

Acacia filicina Willd. Chisos Mountains (Foley County). Our plants show
an unusual reduction of the leaves of this abundant and exceedingly vari-
able species, the pinnw being 2 to 5 pairs, and the leaflets 5 to 10 pairs,

Acacia flexicaulis Benth. Santa Maria (Cameron county). This species
seems to belong to both coasts, having been found by Dr, Palmer at Corpus
Christi Bay, and by Mr. Nealley along the coast of Cameron county; also by
Xantus along the coast of Lower California from Cape St. Lucas northward,
and by Dr. Palmer at Los Angeles Bay.

Pithecolobium (Unguis-cati) Texense Coulter, x. sp. A shrub or small tree
armed with short stout stipular spines, the inflorescence and branchlets pu-
berulent: leaves with 1 or 2 pinne, the lower pair (if any) much the suialler;
leaflets in the upper part of pinnw 3 or 4 pairs, in the lower 1 or 2 pairs,
obliquely elliptical and the terminal pair mostly obovate, venulose and with
more or less excentric midrib, 6 to 10™™ long, 4to6™™ wide: peduneles (about
12" long) apparently in axillary elusters (in fact on very much reduced
branches): spike rather loosely flowered, oblong, 2.5 to 4em long: the stam-
ineal tube exserted: pod coriaceous, becoming very hard and more or less
arcuate, with the thickened edges somewhat impressed between the seeds,
10 to 15™ long, 18 to 25™™ wide, about 8-seeded.—Near Roma (Starr county).
This species bears a somewhat striking resemblance to Acacia Hlexicaulis, and
it is more than probable that it has been eollected and referred to that
species. If collected only in foliage and fruit it would most probably be re-.
ferred to 4, flexicaulis. However, the flowers not only show the indefinite
monadel phous stamens of the tribe Ingee, but the stamineal tube is exserted.
Belonging to the Unguis-cati section, it ditters from those with oblony spikes
in the leaves having usually a second and smaller pair of pinnwe. Its nearest
allies belong to tropical America, some of them reaching north into Mexico.

Cowania plicata D. Don. Chisos Mountains (Foley county). A north Mexi-
can species, reported for the first time within our borders.

branching, 7.5 to 15™ high, villous: leaves very much smaller than in the
species, seldom 12™ long: calyx purple.—Limpia canon (Presidio county).
Quite different in appearance from the species, being much smaller in all its

Gaura Nealleyi Coulter, n. sp. Near to G. suffulta Engelm.; but lower part of
the stem sparingly hirsute, the rhachis, calyx, and bracts glandular-pubescent:

Point Isabel.

Eupatorium Greggii Gray. Chenate Mountains (Presidio county).

Eupatorium solidaginifolium Gray. Limpia cafion (Presidio county). The
thyrsoid panicle becomes much larger and more lax and leafy than in the
type specimens, and anything but ‘‘small,” as in the original description. In
the present specimens the panicle sometimes becomes 15 to 20° long and 14
to 18°™ across the base, being at the same time very lax and leafy. Associated
with these large panicled specimens are others with panicles of the described
dimensions.

Eupatorium Wrightii Gray. Chisos Mountains (Foley county). This beau-
tiful species does not seem to have been reported within our border since
Wright’s original collection, the station of which was in the same general
region as the present collection... Pringle collected it in 1885 in the mountains
of Chihuahua.

Brickellia oliganthes Gray, var. crebra Gray. Chenate Mountains (Presidio

Aplopappus Nealleyi Coulter, ». sp., § Aplopappus proper: From 3 to gam
high, somewhat branching above, glabrous or nearly so and somewhat
glaucous, terminated by long (10 to 12.5°") naked (or minutely bracteate)
peduncles which are enlarged beneath the large solitary heads: leaves narrowly
linear or almost filiform, 2.5 to 5™ long, entire or pinnatifid with two or three
linear lobes: head about 2.5" broad; the involucral bracts oblong, obtuse,
glabrous, dark-veined, lousely imbricated in about three successively shorter
rows: rays ten to fifteen, narrowly linear, 12 to 18" long: disk-flowers with
rather deeply lobed corolla: akenes 10-striate, the strim rugulose and
sparsely pubescent, about 3°" long: pappus of numerous scabrous rufous
bristles: style-tips with short ovate appendages.—Santa Maria (Cameron
county). ‘This species is apparently related to A. tenwilobus Gray, but the
almost smooth akenes and very short style appendages, as well as the smooth
oblong, obtuse and unequal involucral bracts, and leaf characters, serve well
to distinguish it.

Aplopappus rubiginosus Torr. & Gray. Pena (Duval county), and Chenate

Aplopappus spinulosus DC. Screw Bean (Presidio county).

Aplopappus Texanus Coulter, n. sp.,§ Stenotus: Low and somewhat lignescent
at base, glabrous and somewhat glaucons, bearing a few medium-sized
heads: leaves narrowly linear or almost filiform, 24 to 836/™" long, often fasci-
eled in the axils: head 6 to 9"™™ high; the involucral bracts oblong, obtuse
or acutish, glabrous, yellowish tinged, loosely imbricated in about two nearly
equal rows: rays few or none, exserted, ovate, not more than 3"™ long: disk-
flowers with rather deeply lobed corolla: akenes 10-striate, the striw sparsely
pubescent, 3™" long: pappus of numerous scabrous white bristles.—Chisos
Mountains (Foley county). «In foliage and akenes much resembling 4.
Nealleyi, but in size of heads, and character of involucral scales, rays, and
pappus, very different. With the present grouping of species these differences
refer the two species to different sections of the genus.

ending ina long naked (rarely 1 or 2 bracteate) peduncle (15 to 25: long)
bearing a solitary head (with sometimes shorter lateral peduncles): leaves all
opposite, ovate-lanceolate to linear, three-ribbed from the base, from irregu-
larly laciniate or toothed to almost entire, with margins mostly revolute,
tapering at base into a more or less distinct petiole, 2.5 to 5" long: involucre
about 12"" high; bracts ovate, acute or the outer ones acuminate, somewhat
coriaceous at base, hispid, the inner ones with softly ciliate margins, in two or
three series; disk corollas with very narrow tube about as long as the awns,
much enlarged above into a campanulate five-toothed limb : chaftfy bracts of
the receptacle gradually acuminate, with a strong blackish midrib: akenes
narrowly oblong, sparingly pilose or glabrate, longer than the often unequal
scabrous awns which are chaffy at base; the intermediate chaffy palew laci-

Thelesperma gracile Gray. Corpus Christi (Nueces county), Pena (Duval
county), Santa Anna (Coleman county), and Screw Bean (Presidio county).
In the Santa Anna specimens the heads are nearly always radiate, with deep
yellow rays about 6™™ long, and the pappus can hardly be called ‘‘ subulate.”
In fact, descriptions have hardly done justice to the very conspicuous pappus,
which is composed of two lanceolate, retrose, bristly scales nearly as long as
the corella-tube.

Bidens Bigelovii Gray. Limpia canon (Presidio county).

Perityle Vaseyi Coulter, x. sp. Minutely glandular pubescent, simple or with
short branchlets, from a slightly lignescent base, 2 to 31 high, leafy: leaves
large for the genus, 3.5 to 6,0%™ long, including the petiole (which is some-
what shorter than the blade), with broad outline, palmately or pinnately
divided into three long-stalked broadly cuneate divisions; the divisions three
to five-parted; the ultimate segments mostly cuneate and three-lobed : heads
rather few and scattered, on long or short peduncles, 10 to 12™™ high: in-
volucral scales linear-oblong, acute or acuminate, with margins more or less
ciliate at tip: rays 4 to6™™ long, deep yellow, oblong, three-toothed at apex:
disk-corollas funnelform, yellow, 54™™ long: style-tips setaceous-filiform and
hirsute: akenes oblong, pubescent on the faces, hispid-villous on the mar-
gins, 3.5™™ long, crowned with a pappus of bristle-like squamellw and a single
more or less barbellate awn as long as the akene.—Chisos Mountains (Foley
county). Nearest P. Parryi Gray, but decidedly distinct, and in the shape of
the disk-corolla not even a member of the same section.

Florestina tripteris DC. Point Isabel.

Sartwellia Flaverie Gray. Screw Bean (Presidio county).

Flaveriachloreefolia Gray. Screw Bean (Presidio county). Fine specimens

of this imperfectly known species bring to light some additional characters.

The plant becomes more than 6% high, with a thick stem, and the lower
leaves become 7.5™ long and 5™ wide at the perfoliate base. The coarse
glaucons stem, with its broad connate-perfoliate smooth and’ entire leaves,
give the plant the look of an Asclepias. A more important fact is that all the
Nealley material has pappus, composed of two to four thin palew, which are all
on one side, leaving the other side naked. In the Synopt. Flora (p. 354) it is
said that ‘a few flowers were once seen with a pappus of four thin palew.”
As this character appears in all of our abundant material the genus charac-
ter should be amended in that character. It is impossible to admit these
specimens into Flaveria, as defined by Bentham & Hooker or Gray, as ‘‘ no
pappus” is one of its distinctive characters.

depauperate form of L, Cliffortiana L. It also approaches Z. subnuda in
habit, the rosulate tuft of root-leaves being entirely unlike ZL. Cliffortiana,
but the seeds are those of the latter species. If not entitled to specific rank
it should probably become a variety or form of L, Meayana Gray.

Lobelia cardinalis L. Chenate Mountains (Presidio county). The narrow

Gilia Macombii Torr., var. laxiflora Coulter, ». var. Stems from a strong
lignescent base: flowers very loosely cymose or scattered: corolla white
(perhaps a little purplish-tinged), with tube 15 to 18™™ long, and vate
mucronulate lobes 4 or 5™" long: stamens all included.—Camp Charlotte
(Ixion county). The loose inflorescence, larger and white corolla with ovate
lobes, and included stamens, distinguish this variety from the species, which
has only been reported from the mountains of Arizona.

these specimens of C. Greggit have unequally inserted stamens, the whole
flower structure conforming more closely to that of Draperia, a Hydrophyl-
laceous genus, than to Coldenia. In fact, it is a pertinent question whether
this species should not be transferred to Draperia.

Heliotropium angustifolium Torr. Camp Charlotte (Ixion county), Our
plants represent this species in every particular except that the corolla-lobes
are not ‘ovate and acute.” The lobes are those of 1. tenellum. Much of the
“acuteness” of the lobes of H,. angustifolium is apparently the result of dry-
ing.

Ipomeea costellata ‘Torr. Limpia canon (Presidio county).

Ipomea Nealleyi Coulter, n. sp. Glabrous, with slender creeping or twining
stems: leaves thin, triangular in outline, cordate at base with a broad sinus,
angulately three-lobed (the lateral lobes resembling the basal lobes of a
broadly hastate leaf, and often with an additional basal angle), 2 to 3e™ long
and somewhat broader, angles all mucronulate, on slender petioles: pedun-
cles slender, usually a little shorter than the petioles, one-flowered : sepals
foliaceous, glabrous, loose, little if at all imbricated, linear-lanceolate,
acuminate, conspicuous, nearly or quite as long as the tube of the corolla,
12 to 16" long, spreading in fruit: corolla broadly funnelform, 15 to 20mm
long, with purplish blue lobes and whitish tube: globose capsule glabrous.—
Chenate Mountains (Presidio county). Related to J. trifida Don. and its
allies.

Ipomeea sinuata Ortega. Pena (Duval county). Calyx shorter than usual.

Ipomcea Texana Coulter, ». sp. Apparently arborescent, glabrous, or minutely
puberulent, with coarse branches: leaves thickish, entire or nearly so, sagit-
tate, acuminate, the base with inconspicuous rounded lobes or truncate, 6 to
12 Jong, 3.5 to 5™ broad at base, on petioles 3.5 to 7.5°™ long: peduncles
mostly shorter than the petioles, bearing simple or compound few to several-
flowered cymes: sepals short (6 or 7™™ long), somewhat coriaceous, minutely
pubescent, broad and rounded or two-lobed at apex: corolla pink-purple,
pubescent, 5 to 7.5° long.—Santa Maria (Cameron county.) A member of
the arborescent group of Ipomaas, represented by the Mexican J. murucoides
R. & S., to which our plant is related.

diameter.

Dichondra argentea Willd. Chenate Mountains (Presidio county).

Cuscuta Californica Choisy, var. reflexa Coulter, vn. var. Flowers 4 to 5mm
long when tbe lanceolate subulate corolla-lobes are erect, but these soon
sharply reflexed and as long as the tube: calyx-lobes acuminate, about
equaling the corolla tube: scales somewhat prominent and lacerate: styles
about as long as the ovary: corolla marcescent around the two to four-seeded
capsule,—Roma (Starr county). Pringle 783 (collection of 1886), from Chi-
huahua, seems also to be a form of this variable species. Our variety has
some important points of difference from the species and any published varie-
ties, but it seems to be fairly included in the same specific relationship, If
this conclusion is right the range of this Californian and Arizonian polymor-
phous species is extended through northern Mexico and into southern Texas.

pubescent on both surfaces, 5 to 7.5°™ long (including the petiole): invo-
lucres few and long-pedunculate : flowers greenish, occasionally with a pink-
ish tint: sepals lanceolate to ovate, acute or obtuse, the inner ones usually
shorter and broader.—Near Pecos City (Pecos county). A species nearly
related to E. ciliatum Torr. and E. atrorubens Engelm., both of northern
Mexico. Itdiffers from Z. ciliatum in its completely villous leaves and
green flowers ; from £. atrorubens in both these characters as well as the
shape of the leaves; aud from both in that the leaves are not all radical.

The following grasses have been determined by Dr. George Vasey, and inelude the
collections made in southern and southwestern Texas by Mr. Nealley during the three
seasons of 1887, 1888, and 1889. For the plants of the first two seasons no specific
locality can be given, so that when no station is mentioned the general range of
“southern and southwestern Texas” is intended, and the date of collection is either
1887 or 1888. The collection of 1889 may be recognized by having the stations
specified, at least within a county. Special attention was given to the collection of
grasses, so that the following list is a very complete one:

stipe terete, reddish-black, 2.5 long: frond oblong-lanceolate, contracted
below, tripinnatifid, 10 to 12° long, 3.5™ wide, upper surface (especially
when young) white-granular dotted, lower densely coated with a white
powder but becoming less so with age: rhachises, like the stipe, white
granular and conspicuously clothed with rigid brown hairs: pinne sessile,
nearly opposite, triangular-ovate or ovate-lanceolate, pinnately divided into
four to six pairs of sessile pinnatifid obtuse and oblong pinnules, confluent
at the apex; margins unchanged but sometimes becoming reflexed: sori
brown and copious, in a continuous marginal line.—Chenate Mountains

LIST OF PLANTS COLLECTED BY DR. EDWARD PALMER IN
LOWER CALIFORNIA AND WESTERN MEXICO IN 1890.

By Dr. GEO. Vasey and J. N. Rose.

Dr. Palmer spent some three months in Lower California ir?the early
part of this year, and his work has proved very valuable in adding to
our knowledge of the flora of this region. His work has been arduous,
owing to the drought and heat, and the few accommodations to be had in
this wild and sparsely inhabited country ; this, added to his failing health,
has made his work doubly trying.

The following are the places visited, with the date of collection and
the numbers of the plants:

In order that the fullest facility for the determination of the plants of
the collection here described might be available, Mr. J. N. Rose, As-
sistant Botanist, spent some time at Cambridge, Mass., in investigating
and comparing the piants with those contained in the herbarium of
Harvard College. We gladly acknowledge the generous help of various
botanists in the determination of difficult species, and especially that of
Dr. Sereno Watson for his aid in studying many of the type plants in
the Cambridge herbarium.

PLANTS COLLECTED AT LA PAZ, LOWER CALIFORNIA.’

Great interest was felt in Dr. Palmer’s trip to La Paz and vicinity
this past winter and his rich collection has added much to our knowl-

edge of the flora of that region. Dr. Palmer left San Francisco Decem-
ber 25, by steamer, in company with Mr. T. 8. Brandegee, who, landing
at Magdalena Bay, proceeded overland to Cape St. Lucas, while Dr.
Palmer continued to Guaymas, Mexico, and from there returned to La
Paz. In about two weeks, from January 20 to February 5, one hun-
dred and seventeen species were collected. Among these are two new
genera, fourteen new species, and many more very rare ones. The
southern half of the Californian peninsula has been almost unknown
botanically until the last two seasons, when, through the energetic
labors of Dr. Palmer and Mr. Brandegee, many new and rare species
have been brought to the knowledge of science. The few collections
that have been previously made in this region are well known to
botanists. The first collection was made by Mr. R. B. Hinds on the
voyage of H. M. 8S. Sulphur in 1839. Only about one hundred and
. fifty species in all were collected, the larger part being new. They were
from Lower California, at San Quentin, San Bartolomé, Bay of Mag-
dalena, and Cape St. Lucas. Of this number nineteen were collected at
Cape St. Lucas, of which fifteen were described as new species.

No further collections were made in this region until 1859~60, when
Mr. L. J..Xantus spent several months at Cape St. Lucas making a
collection of one hundred and twenty-two species, nineteen! of which
Dr. Gray (Proc. Amer. Acad. V.) described as new. Quite a number of
the others have since been separated from the species to which they
were referred and are described as new. W. F. Fisher got a few things
at the Cape in 1876, and Mr. W. H. Townsend in 1889. Major Rich? is
the first person of whom we have any record who collected at La Paz.
Three other valuable collections have been made in the central part of
the peninsula, which ought to be mentioned here, on account of the
numerous new species they contain (of which Dr. Palmer has re-collected
many)—namely: the collections of Dr. Palmer in 1887, at Los Angeles
Bay, and at Lagoon Head in 1889, and that of Mr. Brandegee in 1889,
from Magdalena Bay to San Quentin. Of the one hundred and fifty
species collected by Mr. Hinds, twenty-five were recollected and ten of
the fifteen new species collected by him at Cape St. Lucas; forty-two
of the one hundred and twenty-two species of Xantus were recollected,
twelve of which were of the new ones of this collection; sixty-three of the
species collected by Dr. Palmer at Guaymas and Los Angeles Bay were
recollected, eight being of the new species described by Mr. Watson
from that collection; seventy-six of the species were collected by Mr.
Brandegee, six being his new species. Of the species collected fifty-
six extend into the United States, mostly into the desert region of
southern California and Arizona; seventy-six have been collected in
Mexico (mostly from the western part); ten extend into Central
America and eight are in South America.

'One was described by Dr. Englemann. 2Collected Lycium Richii Gray.

PAPAVERACES.

Argemone Mexicana L. Called ‘‘ Cardo”; very common in waste places. No. 55.

CRUCIFERZ.

Cardamine Palmeri Watson. Proc. Amer. Acad. XXIV. 38. Only a few plants
found growing in shade on mesas. Flowers white. No. 103.

Lyrocarpa Xanti Brandegee. Proc. Cal. Acad. 2nd Ser. II. 127. This is undoubtedly
the same that Xantus (No. 2) got at Cape St. Lucas. A very common plart
on lowlands in shade of trees and shrubs. Flowers, ‘‘light mauve.” No. 73.

66

CAPPARIDACE2.

Wislizenia refracta Engelm. A common plant, 2 to 3 feet high, in alkali soil,
near the sea-beach. The plant has a fetid odor. Our plant seems to belong
to this species, having the trifoliate leaves and small fruit. It seems distinct
from the type of W. Palmeri, but recent specimens referred to that species by
Watson and Brandegee seem to be intermediate forms uniting these species.
Mr. Brandegee in a recent note (Proc. Cal. Acad, 2nd Ser. II. 128) says he
thinks the distinction very slight. No. 88.

Atamisquea emarginata Miers. A small tree or bush 6 to 8 feet high, with few
stems, but with many short lateral branches, very brittle and consequently
very difficult to make into specimens. The flowers are white and “as finely
scented as orange flowers.” It was found contiguous to the ocean, on sandy
mesas, just coming into bloom. No. 58.

VIOLACES.

Ionidium fruticulosum Benth. Bot. Sulph. 7. This plant is quite variable in its
leaves. The lower part of the stem is often woody, developing considerable
cork and seeming a true perennial. Our specimens seem to cover both the type
and Gray’s variety dentata made from Xantus’s No. 4. Found abundantly under
shade of trees. No. 84.

POLYGALACES.

Krameria canescens Gray, var. paucifolia Rose, n. var. Slightly pubescent, with
weak spreading branches: leaves very small (1 to 2 lines long) and dis-
tant: sepals (3 to 4 lines long) broad, merely acute.

Dr. Palmer collected at Guaymas and Los Angeles Bay, 1887, a plant much
like this in habit and foliage, but with the narrower sepals and spatulate petals
of the type and thus representing an intermediate form. It is proper to state
here that Mr. Brandegee thinks the plant should go into K. bicolor Watson.
While the plant has the petals and larger fruit of this species, it has different
pubescence, smaller leaves, broader sepals, and smaller bracts to the pedicels.
The following is Dr. Palmer’s note: ‘‘ Found upon mesas and edges of ravines
among other plants, at the base of which they grow, and by which the weak
stems are supported, making by the many interlacing branches a thick mass,
which appears like a parasite. Not seen by itself. Found but one plant with
seed ; the seed-pods had sprouted upon the plant, forming three rather fleshy
leaves like the leaves of the plant and of a bronze color. Flowers mauve.”

No. 4.
CARYOPHYLLACESA.

Drymaria crassifolia Benth. Bot. Sulph. 14. Abundant on sandy beach, No. 6of
Xantus. First collected by Hinds at Cape St. Lucas. No, 142.

PORTULACACES.

Portulaca pilosa L. (?). Probably this species, but material insufficient for perfect
determination. Common on beach and under trees contiguous to ocean. It is
very tenacious of life, specimens before me having been ip press for almost
three months and still nearly as green as when collected, No, 140.

MALVACES.

Spheeralcea Californica Rose, n. sp. Two to 4 and sometimes even 10 to 12 feet
high, densely stellate-pubescent, becoming somewhat glabrate below: leaves
triangular-oblong, 14 to 24 inches long, cordate or truncate at base, more or
less 3-lobed, crenately-toothed, densely stellate-pubescent: inflorescence open
paniculate; flowers orange-yellow: calyx 2 to 3} lines long, its lobes ovate-
acuminate: petals 5 lines long, obovate: capsules small, depressed ; carpels

67

12 to 16, strongly reticulated below, the sterile part a mere incurved acutish
tip; ovule and seed one.
S. Coulteri Brandegee. Proc. Cal. Acad. 2nd Ser. II. 135.

One of the most common plants of Lower California. Dr. Palmer found it in
the ravines and sandy spots contiguous to the beach at La Paz, growing 2 to3
feet high. Mr. Brandegee writes me that in moist places it is 1U to 12 feet high.
It isa rough, homely plant, avoided by all grazing animals. In habit and pubes-
cence the plant resembles Xantus’s (No. 10) plant from Cape St. Lucas, but the
carpels are entirely different, in fact they are almost the exact counterpart of
those of S. Coulteri Gr. This strong similarity has led Mr. Brandegee into the
error of referring his specimens of last year to this species. While the carpels
are so similar and like no other Spheralcea, still there seems aslight difference.
S. Coulteri Gr. is less pubescent and the terminal part (wrongly called the
‘horizontal projection at base” by Watson and Brandegee) is very broad and
obtuse. 8. Californica is said by Mr. Brandegee to be an annual, but appears
to be biennial or perhaps perennial. 8S, Coulleri Gr., originally described as per-
ennial, is clearly an annual, It is also very different in habit; S. Coulteri Gr.,
is either procumbent or with branches ascending, while 8. Californica is tall and
erect. The pubescence is very different as well as the shape and toothing of
the leaves, and the size and color of the flowers. No. 18.

Horsfordia Palmeri Watson. Proc. Amer. Acad. XXIV. 40. Six feet high, with
single upright stem and many lateral branches: lower leaves 4 to 5 inches long,
Common on sandy mesas, called ‘‘Mariola,” and much used as a remedy in
female diseases. No. 96.

Worsfordia rotundifolia Watson. Proc. Amer. Acad. XXIV. 41. Found sparingly
on astony ridge. No. 117.

Sida Xanti Gray. Proc. Amer. Acad. XXII. 296, Collected by Xantus 1859-’60, but
not described until three years ayo. The flowers are described as ‘‘ apparently
white but perhaps yellow.” Dr. Palmer speaks of the ‘‘ golden-colored bloom,”
but in the plants before us there isa purplish tinge. The few plants obtained
are from astony ridge. It grows 3 to 4 feet high, with two or three slender
stems from the base and few lateral branches. No. 27.

Abutilon PalmeriGray. No. 90.

Abutilon incanum Don. A plant 3 or 4 feet high, growing in sandy gulches among
shrubs. No. 120.

STERCULIACEZ.

Hermannia Pa'meri Rose n.sp. Stems perennial, weak, the long slender branches
supported by other plants, densely stellate-pubescent : leavesdeltoid in outline,
cordate at base, 6 to 12 lines long, dentate, on petioles 4 to 8 lines long: ped-
uncles slender, 6 to 15 lines long, 1 to 2-tlowered, articulated at the upper bract,
becoming reflexed: calyx 3 to 4 lines long, deeply cleft into lanceolate acute
lobes, not enlarged in fruit: corolla golden yellow; petals 4 to 5 lines long,
orbicular, cuneate at base, with an abrupt tip, spreading or reflexed: stamens
5; filaments very short; anthers erect, free but connivent asin Solanum: styles
cohering: capsule 6 lines long, oblong, the dorsal crest of each capsule armed
with long glochidiate spines ; seeds 5 to 7 in each cell, somewhat incurved, the
hilum end somewhat pointed, the surface dull with irregular depressions.
Grows under shade of bushes on sandy mesas. Also collected at Todos Santos
by Mr. T.8. Brandegee. No. 29.

Melochia tomentosa L. An upright growing shrubby plant, about 6 feet high, on
mesas. Collected by Xantus (No. 13), and also at Magdalena Bay, etc., by
Brandegee. No. 121.

MALPIGHIACES.

Galphimia angustifolia Benth., var. oblongifolia Gray. Small plants under shade
of trees, bloom yellow. This is the same as the more recent G. linifolia of Gray,

68

which Hemsley in Biol. Centr.-Amer. has retained, reducing Bentham’s name
toasynonym. Xantus (No. 15) collected the typical form. No. 109.

Janusia Californica Benth. Bot. Sulph.8. Plant 4 to 6 feet high; hangs for sup-
port on other plants; along arroyos. Flowers yellow. No. 42.

ZYGOPHYLLACEA.

Larrea Mexicana Moric. Called ‘‘ gobernadora,” and is used in hot baths for the
cure of rheumatism. No. 54.

BURSERACES.

Bursera microphylla Gray. ‘‘ Torote,” a low tree 10 to 15 feet high, a foot or more
in diameter, with a much-branching top. The bark is used for dyeing and tan-
ning and is largely shipped to England. An injection made from the bark is
used for gonorrhea, and a drink prepared from the gum is taken for the same
disease. No. 64.

Cardiospermum Palmeri Vasey & Rose. Proc. Nat. Mus. XIII. 147. A climbing
plant not much seen. One plant only, found in bloom on the bank of a ravine.
A part of the type. No. 68.

Cardiospermum tortuosum Benth.? About 4 feet high, puberulent becoming
glabrate and thorny ; thorns 6 to 12 lines long, 2 to 3 forked at tip. Flowers
few, white. Perhaps this species, but more glabrous and thorny than Mr.
Bentham’s form; it answers better Xantus’s No. 19 referred as ‘“‘Cardiospermum?
sp.nov.” by Dr. Gray. No. 2. ;

LEGUMINOSZ.

Coursetia glandulosa Gray. Proc. Amer. Acad. V. 156. The specimen of Xantus
(No. 25) upon which this species was founded was merely in flower and it was
doubtfully referred to this genus. Our plant has smaller leaves than the type
and is much like larger-leaved forms of C. microphylla Gray, which perhaps
will be referred to this species. A small tree, 15 feet high, with loose growing
branches. ‘‘ Bloom, lower part light yellow, upper white.” Found in low
places near a dry creek. No. 38.

Dalea chrysorhiza Gray. Proc. Amer. Acad. V. 156. The type was first collected
by Xantus (No. 22) at Cape St. Lucas; not collected since until last season, by
T. S. Brandegee, at Cardon Grande. It is a trailing plant on sandy bottoms.
Flowers ‘‘mauve-colored.” No. 71.

Dalea maritima Brandegee ined. Very common on sandy beach near the ocean.
No. 79.

Dalea Emoryi Gray. The plants grow on sandy beaches in masses covering very
large spaces. The stems are procumbent and with interlacing branches hide
the ground. They have a white appearance and at a distance look like dry
hay. Occasionally a glabrous plant is found growing with others, a fact also
noted by Mr. Brandegee. No. 3.

Cracca Edwardsii Gray. Found growing in shade of bushes. ‘‘ Bloom, cream-col-
ored; on the upper part red striped, turns reddish by age.” No. 51.

mon sbrub with two or three main branches. No. 114.

Cesalpinian.sp. A compact shrub4 feet high, brown bark, younger parts somewhat
pubescent and with stipitate glands: leaves small (the petiole and rachis with
stipitate glands) with one pair of pinnze ; leaflets 5 pairs, excentric, oblong, 2
to 4 lines long: racemes short-pedunculate, 1 to 3 inches long; bracts ovate,
obtus-, laciniate, caducous: pedicels slender, jointed near the summit: sepals 3
lines long, purple (‘ bronzed”), covered with stipitate glands: petals 5 to 6
lines long, yellow, more or less glandular: stamens somewhat villous: pods
not seen.—On stony ridges. An abundant bloomer with fragrant flowers “ as
sweet as apple blossoms.” Collected by Palmer in 1887 but not reported in Mr.
Watson’s list. No. 95.

Heematoxylon boreale Watson. Proc, Amer, Acad. XXI, 426. ‘ Loose, thorny shrub,
8 to 10 feet high; has in the young leaves a peculiar bronze color; the older
leaves fall when the new ones appear. The wood yields a dye.” No. 48.

Cassia Covesii Gray. Called ‘‘Oyason;” the roots and stems are used as a blood
purifier, and by the common people in the making of poultices and in hot
baths for the cure of certain diseases. No. 52.

Parkinsonia Torreyana Watson. Called ‘‘ Palo Virde.” A low tree with branch-
ing top. ‘‘Just coming into flower” (Feb. 1). Perhaps this is the same plant
collected by Mr. Brandegee in 1889. No. 112.

Acacia Wrightii Benth. A thorny shrub 6 feet high, with few stems. ‘The flow-
ers have a pleasant honey-like aroma.” No. 94.

Acacia Farnesiana Willd. Called ‘‘ Vinorama.” A small tree with loose branches.
The outer bark when fresh is used to cure headache, and the pods were once
used to make ink. ‘‘The flower very aromatic, honey-like.” It is No. 34 of
Xantus. No. 60.

Acacia flexicaulis' Benth. Stamens numerous, united into a tube longer than the
corolla tube; pods curved, rough, black, an inch broad, 3 inches long. This is
called ‘ Palo fierro” (iron wood), and is a very useful plant. Although often
asmall tree, Dr. Palmer only found it at La Paz as a low thorny bush with
rough scraggy branches. Flowers white. No. 86.

Lysiloma candida Brandegee. Proc. Cal. Acad. 2nd Ser. II. 153. Called ‘ Palo
blanco” (white wood). The bark is used for tanning purposes, while the wood
is used in many ways. Only small trees, 12 to 15 feet high and 6 inches in
diameter, were seen. Grows along arroyos. Flowers white. No. 80.

Calliandra eriophylla Benth. A small plant 2 feet high with compact top. The
stamens are white tipped with red. On mesas. Not common. No. 72.

Calliandra, sp. Belongiug to Bentham’s series Nitide, near C. Californica, or it may
be C. Cumingii. The pinne are always6 pairs, and leaflets about 20 pairs; the
leaflets 2 to 3 lines long, midvein eccentric, a little pubescent, acute: peduncle
14 to 2 inches long, with numerous flowers: calyx less than a line long: petals
3 lineslong: pods 24 to3} inches long, considerably tapering at base, with thick
margins, and a little puberulent. Only a single specimen collected, growing
in a garden at La Paz. It is called ‘‘ Tabardillo,” by which name yellow fever
was known to the Indians. The root of this plant is now used by the people
of this region as a remedy for fevers. No, 22.

Turnera diffusa Willd., var. aphrodisiaca Urban. Jahrb. Bot. Gart. Berl. II. 127.
Dr. Palmer writes of this plant as follows: ‘‘This plant is widely known in this
locality under the name Damiana. It has a wide medical reputation as a
stimulant in exhausted vitality and for the cure of syphilis, and as a blood pu-
rifier used in the form of hot teas. All over the peninsula where it can be had
it is used as a substitute for China tea; it has a pleasant flavor unlike any
other plant. It is made into preparations with spirits and sold by druggists
for its strengthening qualities. It refreshes one greatly when fatigued, allevi-
ates nervous diseases, cures colic, and is an efficacious diuretic. It is put up at
La Paz in large quantities. Flowers close at night.” No. 11.

on mesas. ‘The plants are small, with linear leaves. No. 36.

RUBIACES.

Houstonia asperuloides Gray. Proc. Amer. Acad. V. 158, This species is quite
variable. A good figure (No. 13) appears in Botany of the Sulphur. The
corolla tube is sometimes slender filiform, as figured, in other specimens broader,
gradually running into the calyx. Some (No. 31*) are quite glabrous, with
long filiform pedicels and slencer branches; others are somewhat granulate,
with capsules short and sessile or glomerate in the axils and the whole plant
depressed. ‘‘Corolla pink.” Collected first by Hinds of the Sulphur in 1837
and by Xantus (No. 43) in 1859-’60, both at Cape St. Lucas, and probably by
Mr. Brandegee, 1489, at Magdalena Bay. Common on sandy plains and mesas.
No. 24 (in part), 31°.

Houstonia Brandegeana Rose, n. sp. Near the last but more erect, with slender
branches: pedicels long and slender, sometimes 14 inches long: calyx 4 line
long, with short erect obtuse lobes: corolla 3 lines long, with slender tube two
or three times the length of the calyx, with broad funnel-form throat and ob-
tuse lobes ; the throat yellowish green ; the limb violet: capsule globose (4 line
long), not tapering into a long, narrow base.—Habitat the same as the above.
No. 31 and 248,

Houstonia arenaria Rose, n.sp. A taller species, much branching, glabrous: leaves
lanceolate, 9 to 15 lines long by 2 to 3 lines broad; stipules laciniate: flowers
numerous, either sessile in the forks, or along the rachis, or on filiform pedicels,
3 to 4 lines long: calyx-tube with small obtusish lobes: corolla ‘pure white,”

COMPOSITZ.

Hofmeisteria fasciculata Walp. Rep. VI. 106. Colleeted by Hinds, Xantus (No.
46), and Brandegee. It is illustrated in Bot. Sulph under Helogyne. Very
abundant in crevices of rocky bluffs facing the ocean. Whole plant light
green, about a foot high, leaves very fleshy, flowers rose-colored. No. 137.

Aplopappus arenarius Benth. It is undoubtedly a true Aplopappus and probably
Bentham’s species from Cape St. Lucas. It does not appear to be Xantus’s spe-
cies, referred here by Gray. The 4. spinulosus of Brandegee, from San Gregoria,
probably belongs with it. The style tips are deltoid and the akenes are turbi-
nate, and 8 to 10-ribbed. Found on the mesas and exposed places. A compact
plant and an abundant bloomer. No. 17.

Coulterella,' n. gen. (Plate I.) Heads 1-flowered (rarely 2), in cymose, glomerate
clusters. Flowers tubular, fertile. Proper involucre tubular, of three united
bracts, 3-toothed at apex, winged in fruit, inclosing the ovary and corolla tube
and permanently investing the akene. Corolla regular, with narrow proper
tube and deeply cut into lanceolate divisions longer than the tube. Stamens
inserted high up in the tube; anthers wholly exserted, sagittate at base. Style
branches elongated and obtuse, papillo-e. Akene linear-cuneate and terete;
pappus a minute annular crown or obsolete.—A compact shrub, glabrous and
succulent. Leaves opposite, entire or dentate, sessile. Corolla yellow. Prob-
ably belonging to the tribe Helianthoidew, sub-tribe Lagascee, but possibly of
the tribe Jnuloidew, and a relationship has been suggested with Gray’s little
Dimeresia of Oregon. The opposite leaves, broad style-branches and merely
sagittate anthers seem to more properly refer it to the former tribe. Named
in honor of John M. Coulter, editor of Botanical Gazette and author of numer-
ous botanical works.

Coulterella capitata, n. sp. A shrub with many branches, forming a large bush 4
feet high: leaves very fleshy, about an inch long, with few spiny dentations:
the glomerate clusters loose, 6 to 25-flowered, each head in the axil of a small
setaceous bract: corolla lobes 3-nerved, 2 lines long: involucre in fruit 3 to
4 lines long, spongy, 3-angled or winged: akenes 14 lines long: the plant
has a strong aroma of the oil of lemon,—Rare, on a sandy beach near the ocean.
No. 136.

Viguiera deltoidea Gray. Proc. Amer. Acad. V. 161. Dr. Palmer has collected
this species again, near the original station. He says ‘‘ its several stems form
a compact, shrubby plant,8 to 10 feet high, blooming abundantly. It is very
common along gulleys and among trees and shrubs on the mesas. This plant
is much taller than was originally supposed. The leaves are either alternate

Greene), of more northern range; the southern form passes into the type.
No. 30.

Viguiera tomentosa Gray. Proc. Amer. Acad. V. 161. This is a very rare species
in herbaria and is only known before from the collection of Xantus (1859-60),
from the vicinity of Cape St. Lucas. An upright growing plant with several
woody stems. It has a large, loosely hanging top; a very free bloomer. Com-
mou On arroyos and on mesas. No. 83.

Encelia Palmeri Vasey & Rose. Proc. Nat. Mus. IX. 535. These specimens have
somewhat smaller leaves, either cordate or cuneate at base; the akenes obo-
vate. Dr. Palmer says it isa very common plant here. It is 3 feet high, in
compact masses, and is a very showy plant. It has been collected by Mr.
Brandegee at Magdalena Island and San Gregoria. No. 15.

Encelia farinosa Gray. Only a single plant collected. It is called ‘“ Incienso,” be-
cause of the gum which the woody part yields being used by the priests in
early times for incense. It is amber-colored and has a pleasant aroma. Not
before collected so far south. Mr. Brandegee has referred here his E. radians.
No. 50. .

Bidens Xantiana Kose, n. sp. Stems terete, a foot to 15 inches high, slender and
somewhat spreading at base, glabrous throughout: leaves much shorter than
internodes, opposite, bipinnate with short linear segments: head on* long
peduncles: the outer involucre of short linear bracts, the inner longer, ovate
and acute: disk about 3 lines high; rays 8, about 5 lines long, styliferous:
akenes 2-awned.—We name this species for Xantus, who collected here in
1859-’60. It seems nearest B. angustissima H. B. K., but differs in its terete
stem, shorter leaflets, and glabrous involucre, It differs from most Bidens in its
styliferous rays. Only a single plant seen; this grewin a shady arroyo. No. 5.

Leptosyne parthenioides, var. dissecta Watson. Proc. Amer, Acad. XXIV. 56.
Very similar in habit to this form. It is L. heterocarpha Gray, and if this spe-
cies is not to be kept distinct, as is held by Mr. Watson and Mr. Brandegee, it
should be referred to this variety and not to the species proper, where it is
assigned by these authors. The akenes are smaller than in the species proper;
the dissected wings thick and corky, and the awn retrorsely hispid ; this was
noticed by Mr. Brandegee, but in Bentham’s figure (Bot. Sulphurt. 16) they are
upwardly hispid. No. 62 of Xantus. Found in only a few places in the shade
of trees. No. 19.

Perityle Emoryi Torr. A common plant in sandy, alkaline plains, near the ocean.
Very succulent plant; difficult to dry. No. 78.

stomach, No, 64 of Xantus. No. 8.

Dysodia speciosa Gray. Proc. Amer. Acad. V. 163. Rather plentiful, growing near
and supporting itself upon other plants. Its bright amber flowers and strong
bergamot aroma make it a very attractive plant. No. 65 of Xantus. No. 32.

Pectis Palmer! Watson. Proc. Amer. Acad. XXIV. 58. Stony ridge. Very rare.
only known before from Palmer’s 1887 collection from Guaymas, Mexico. No.

Solanum Hindsianum Benth. Bot. Sulph. p. 30. This species was collected by Xan-
tus (No. 84), and referred by Dr. Gray in Proc. Amer. Acad. vol. V, and also in Syn.
Flora to S. eleagnifolium, but in a recent note he says ‘“ perhapsdistinct.” In
habit the two are very similar, but in our species the flowers are much larger

, (ld4inches in diameter) as well as the fruit, and on shorter, thicker, aid mostly
erect pedicels. Dr. Palmer says of it: ‘A common upright growing plant with
few stems and showy light purple flowers.” Found on mesas. The following
have been referred to this species; Pringle (1884), Sonora; Palmer, Guayinas ;
Orcutt (1886) San Quentin. No. 25.

Physalis crassifolia Benth. Flowers 6 to 8 lines broad. Yellow, with a dark eye.
Anthers yellow, called “tomate capotillo.” The fruit is edible. Mr. Brande-
gee thinks P. glabra should be referred to this species. Our plant is not the
same as P. glabra of Xantus’s collection from Cape St. Lucas. Only a few plants
collected, growing under shade of bushes. No. 76.

Lycium umbellatum Rose, n. sp. Large, compact, shrubby plant, 8 to 12 feet high,
with somewhat viscid pubescence: leaves fleshy, oblong to ovate-oblong, 1 to
1} inches long: flowers solitary in the axils of the leaves or in umbellate cluster
at the end of the branches; pedicels 4 lines long: calyx 24 lines long, with
acute lobes: corolla purple, 7 lines long, five-lobed : stamens included, glandu-
lar-pubescent at base.—Very common in alkali land or in sand near the beach.
A species near L. Fremonti of Arizona. No. 13.

Lycium Andersonii Gray? A loose-growing plant, with many stems, 6 to 8 feet
high: flowers white, berries red, edible: leaves narrowly spatulate, sometimes
over an inch long; pedicels of variable length: corolla 4 lines long, the sta-
mens exserted : fruit smaller than in L. Andersonii.—Grows in alkaline soil near
the ocean. No. 101.

Nicotiana trigonophylla Dunal. Thisiscalled ‘‘ tobacco cayotte,” and was formerly
used by the Indians. Common in the sandy arroyos. Formerly referred to N.
ipomopsiflora (Xantus, No. 83), but in Syn. Flora placed under this species. Mr.
Brandegee, however, keeps it distinct. No. 75.

SCROPHULARIACEZS.

Antirrhinum cyathiferum Benth. This plant has been collected at Magdalena Bay,
Hinds, Brandegee; Guaymas, Palmer and Echrenberg; and in Arizona, Pal-
mer. From the latter collection was made Gray’s A. chytrospermum (Proc.
Amer. Acad. vol. XII.), since very properly referred to the above species by
Mr. Watson. The calyx teeth and length of corolla tubes upon which Gray’s
species was founded are variable characters. A good figure of this species
appears in the Botany of the Sulphur (t.19), but the calyx teeth are some-
what exaggerated. Grows in sandy spots not far from the ocean. “Purple
flowers, fleshy stems.” No. 91.

Conobea intermedia Gray. Plant very rare abuut La Paz.on rocky ledges. Corolla
purple, This is the only specimen we have seen from Lower California. No. 81.

Calophanes peninsularis Rose, n. sp. A compact shrubby plant 4 feet high, but
young parts and inflorescence glutinous: leaves small (about 1 inch long),
ovate to ovate-lanceolate on short petioles: flowers axillary or on short lateral
branches: bracts small, deciduous: calyx 3 lines long, deeply cleft into five
narrow acute divisions: corolla purple, 15 lines long, regular, with five short
obtuse lobes, a broad open throat abruptly contracted into a distinct, slender
tube 5 lines long: stamens didymous; anthers mucronulate: capsule, including
the thick solid stipe, 9 lines long, covered with short stipitate glands, 4-seeded
(two to each cell), these flat and thin.—Common on the mesas about La Paz.
No. 20.

Carlowrightia cordifolia Gray. Proc. Amer. Acad. XXIV. 406. <A rare plant,
growing under shade of bushes on mesas. This plant differs from the poor
specimens of the type in the National Herbarium, which has the flowers
arranged unilaterally along the spike, and the leaves more strongly veined.
The corolla also is described as being white, while Dr. Palmer writes that
these are canary color. Mr. Brandegee also referred here a plant from farther
north. Dr. Palmer got the type from Batopilas, Mexico. No. 107.

Beloperone Californica Benth. Only two plants seen. No. 98 from the edge of an
arroyo. Only a few slender branches in bloom at the top of the plant, which is
5 feet high. No. 99, near the bank of a dry creek, was also in poor condition,
but contained a few capsules as well as flowers. The seeds are smooth (as Mr.
Brandegee has pointed out) and not “ coarsely rugose,” as stated in Syn. Flora.
Our seeds are somewhat wrinkled. Nos. 98 and 99.

Justicia insolita Brandegee. Proc. Cal. Acad. 2nd ser. II. 195. Grows under shade

Justicia Palmeri Rose, n. sp. About 3 feet high, cinereous, puberulent: leaves lan-
ceolate, 2 inches long, on short petioles, glabrous, or with a little appressed
pubescence: flowers few, on small axillary branches or forming terminal pani-
cles: bracts 3, foliaceous, spatulate, 3 to 5 lines long, the central one longer
and broader: calyx small, 14 lines long, deeply 5-cleft: corolla scarlet, about
1 inch long, deeply bilabiate, its tube 6 to 7 lines long; lower lip 3-cleft, its
oblong lobes 3 to 4 lines long; upper lobe with a slight notch: stamens 2, in-
serted in the throat; anther cells 2,pa rallel, unequally inserted, the lower one
mucronate: capsule glabrous, 7 lines long, the stout stipe a little more than
half its length; seeds 4, 2 lines long, flattened, cordate orbicular rugose.—The
seeds of this species are very similar to those of Sipkonoglossa Pilosella Torr., but
in other respects it is quite different. Found growing in shade on an arroyo.
Very rare. No. 97,

SALICACES.

Willow collected :

Salix bonplandiana H. B. K., var. pallida Anders. Monog. Sal. 18, DC. Prodr. 162,
200. Salix nigra Marsh., forma serotina (?) This appears to bear the same rela-
tion to more northerly forms of S. nigra which the serotinous state of S. lasio-
lepis, at one time recognized as a good species, does to the normal development
of typical lasiolepis. The appearance of the aments in the axils of the mature
leaves is the result of climatic influences, and would seem to be in the former
instance, as it is well-known to be in the latter, of no significance, not even
as indicating a variety. The leaves are not thinly puberulous, as they are
said to be in the type specimens from Mazattan, but this character is so incon-
stant in forms of this yroup that its absence only calls for mention because of
the undue prominence given it in describing S. pallida Kunth.

SAN PEDRO MARTIN ISLAND PLANTS.

Dr. Palmer visited this island! two years ago, making a collection of
nineteen species, twelve of which were considered peculiar to the island.
On February 13 of the present year he spent one day on this island
and obtained but three plants, all Composit. One is the new genus
Pelucha of Mr. Watson, now collected in splendid condition and in
abundance. Another proves to be a new species of Hofmeisteria, and
the third a Perityle, new to the island. Dr. Palmer makes the follow-
ing note with reference to the flora of the island: These plants did not
bloom during the rainy season of 1887, as they are winter bloomers.
There is no especial flora making its appearance, as has been supposed,
during the winter. No rain has fallen since early in November, and all
plants except those deeply rooted are dry and dead. The following is
a list of the twenty species known to inhabit the island. Those which
are peculiar to the island are marked thus.*

*Spheeralcea, sp. Perityle Emoryi Torr

Abutilon aurantiacum Wats. Trixis angustifolia DC., var latiuscula
Petalonyx linearis Greene. Gray.

Mentzelia adherens Benth. Nicotiana trigonophylla Dunal.
Echinopepon insularis Wats. Stegnosperma halimifolia Benth.

Cereus Pringlei Wats. Euphorbia petrina Wats.

Opuntia? Ficus Palmeri Wats.

Hofmeisteria laphamioides Rose. Cyperus aristatus Rottb.

Baccharis sarothroides Gray. Muhlenbergia tenella Trin.

*Pelucha trifida Wats.

1 For note concerning this island see Watson. Proc, Amer. Acad, XXIV. 37,

_ 79

Hofmeisteria laphamioides' Rose, n. sp. Shrubby, 3 feet high, glandular pubes-

cent: leaves opposite or alternate above, 6or8 lines long, on petioles somewhat

longer, triangular, doubly crenate: flowers in small corymbose clusters, some-

times pedicels very short: involucre 4 lines long, of linear-acuminate bracts in

about 3 series: flowers numerous: corolla white, 24 to 3 lines long: style

deeply cleft, much exserted: pappus of 8 to 10 scabrous sete, alternating with

as many palew.—Very common over the summit of San Pedro Martin Island.
February 13.

Dr. Palmer says: ‘‘A compact plant with dense green leaves just coming
into bloom.” This plant was collected by Dr. Palmer on the same island (No.
406) in 1887, but in very poor condition. It is the Laphamia (7?) sp., Proe.
Amer. Acad. XXIV. 37. No. 148.

Pelucha trifida Watson. Proc, Amer, Acad. XXIV. 55, This plant was described
as anew genus by Dr. Watson last year. Dr. Palmer has now collected it in
great abundance. The stems are covered with a white tomentum, forming a
strong contrast with the abundant golden-yellow flowers. It has a very strong
aroma asof cloves and cinnamon, and so powerful is this at times that it causes
persons to sneeze and cough. No. 150.

Perityle Emoryi Torr. This is the same form collected by Dr. Palmer at Los An-
geles Bay (No. 562), 1887. Only two plants found at the south end of the
island. No. 149.

RAZA ISLAND PLANTS.

Dr. Palmer spent one day (February 12, 1890) on this island, and col-
lected eight species of Phanerogams with one lichen. The following is
from his notes:

Isla Raza is an island 136 miles northwest from Guaymas, and from 45 to 50 miles
west from San Pedro Martin Island. It is three-fourths of a mile long (from east to
west) and half a mile wide; it rises about 100 feet above the water; being covered
with a deposit of guano, it has a whitish appearance. The island is exceedingly
rocky, except a few low places which seem to have been subjected to the action of
large volumes of water; these spots produce a few varieties of plants which are
usually found upon alkali soil (some of the same plants were found on the rocky sur-
faces also). Above these places were found three patches of Cactus. One plant of
Cereus Pringlei, 10 feet high, stood among loose rocks above high tide. There had
been no rain-fall on the island for more than a vear.

Opuntia tunicata Lehm. Our plant seems the same as that of Parry and Palmer’s
distribution ; fruit 6 to 10-jointed. A few small patches seen in exposed places
among rocks. No. 160.

Opuntia echinocarpa Engelm. & Bigel. A few small patches among rocks. Notin
flower, and but few scattered fruits. No. 161.

Sesuvium Portulacastrum L. A very common plant in large patches near the
salt water. Dr. Palmer says this plant has been often mistaken for a low
grass by persons passing the island. In its exposed position and dense green
color on a barren island of almost total whiteness it would naturally command
notice by passing vessels. No. 153.

Salicornia ambigua Michx. Only two small patches of this plant seen near the
beach. No. 152.

1Dr. Palmer has since collected this species at Santa Rosalia, but a more glabrous
form with the lower leaves oval and with cordate base. The plant is quite bushy,
2 to 24 feet high, with fleshy leaves, just coming into bloom March 1.

80

.

Atriplex dilatata Greene. Pitt. 1. 264. Grows on low places on the island without
rocks. No. 155 is the fertile plant, and 156 is the sterile plant. Dr. Palmer
says the sterile heads are purple before opening. Nos. 155 and 156.

Atriplex insularis Rose, n. sp. Diccious, woody below, 5 to 6 feet high, much
branched, glaucous throughout: leaves 9 to 15 lines long, oval with cuneate
base and broadly spatulate, on short petioles, obtuse or retuse: inflorescence of
male plant almost naked and a dense panicle of gloimerules; of female plant a
dense somewhat leafy spike: bracts a line long, a little broader than long,
with truncate apex and with small teeth, the sides with two conspicuous toothed
crests.—One cf the commonest plants of the island, It grows in the low places
where there are no rocks, and in the rocky ledges wherever there is soil. No.
158 is the fercile plant and 159 the sterile. Our species seems nearest A. Palmeri
of Guadalupe Island, but is very different in its bracts, ete. Nos. 158 and 159.

No. 157. An unknown shrub without flowers or fruit, and almost destitute of leaves.
Only a few plants seen. It.resembles Pluchea borealis.

No. 154. Also, in poor condition, a perennial with many small pubescent leaves.

SANTA ROSALIA AND SANTA AGUEDA PLANTS.

From San Pedro and Raza Island Dr. Palmer visited two places on
the eastern side of the peninsula of Lower California, namely, Santa
Rosalia and Santa Agueda. At the first-named place he spent ten days
(February 20 to March 3), and after visiting Santa Agueda returned
for another day (March 15). This locality is 92 miles nearly northwest
from Guaymas. The country is hilly and rough, covered with rocks.
Only two heavy rains have fallen this season; the strong northwest
winds which prevail here soon destroyed any indication of rain. Only
the most favorable circumstances admit of plants blooming at this
season.

March 4-5 was spent at Santa Agueda, 10 miles from Santa Rosalia.
Dr. Palmer says this locality is watered by springs and surrounded by
low stony mountains, with a thin, diversified vegetation that now looks
parched ; even the cactus is without flowers. The small patches of land
that can be cultivated afford but few plants, and the great number of
domestic animals kept here (owing to the springs) devour everything
outside of the inclosures except what is so absolutely bitter or thorny
that they can not doso. All the veyetable used by the miners a. Santa
Rosalia are brought from this place.

CRUCIFERS.

Draba Sonore Greene. Bull. Cal. Acad. II. 59. In an abandoned garden. To this
species Palmer’s 611, from San Quentin, should have been referred. Santa

POLYGALACES.

Krameria canescens Gray, var. paucifolia Rose. Dr. Palmer says it is ashrub with
many branches, which interlace, forming a dense mass. The older wood is of a
copper color, and the flowers of a plum color. The wood is said to yield a yel-
low dye. It imparts a cherry-red to water. It is commonly called ‘ Mezqui-
tilla.” Santa Agueda, March 4-6. No. 252.

TAMARISCINE.

Fouquiera spinosa H.B.K. A thorny bush 5 to 16 feet high, according to soil, with
the trank 1 to2 feet long and 6 inches in diameter. The flowers are bright scar-
let, clustered at the ends of the branches. In the old plant the bark breaks
away and gives off a gummy substance. The wood is hard and makes a very
good fire, and when burning gives off a pleasant odor. Santa Rosalia, March
15. No. 266.

MALVACEZ.

Spheeralcea albiflora Rose, n. sp. Two to 2} feet high; slender, densely covered
with white stellate pubescence: leaves oval to ovate, 9 to 18 lines long,
the petiole somewhat shorter, somewhat rugose, subcordate base, crenate mar-
gin: flowers white, 6 lines broad, in short axillaryelustered racemes: calyx 3
lines long, with slender acutish lobes: carpel reniform, a full line long, the
lower part strongly and finely reticulated, the upper and sterile part very
small.—In a cation growing in shade, near Santa Rosalia, March 3.

This plant mostly resembles 8. sulphurea of Guadalupe Island in habit and car-
pellary structure, but the pubescence lacks the tomentum, the calyx lobes not
so broad; the carpels, while similar, are easily separated ; the carpel is slender
and shorter, with stronger and finer reticulations and a shorter sterile part. In
habit resembling S, axillaris, but with very different carpels. No. 205.

Spheralcea violacea Rose, n. sp. Simple stems about 3 feet high, densely covered
with a stellate pubescence: leaves ovate to lanceolate acuminate, 2 to 24 inches
long: calyx, 24 lines long, its lobes ovate, acute: petals, 5 lines long, lilac: car-
pels 1 to 1} lines long; the sterile part about half the length of the carpel,
obtuse.—Growing in shade at Santa Rosalia, March 15, and seemingly not
common.

Resembling in habit some specimens of S. Fendleri in the Gray Herbarium
but with very different carpels. The carpels most resemble those of Xantus’s
plant (No. 10) from La Paz, but the sterile part of the carpel not so large. No.
206.

Horsfordia Newberryi Gray. Fourio6 feet high: lower leaves (including petiole) 5
to 7 inches long: flowers golden-yellow. Gravelly arroyos and sandy hillsides,

yinta Rosalia, February 14 to March 3. No. 169.

medicinal value. Santa Agueda, March 4 to 6. No. 251.

ZYGOPHYLLACES.
Pagonia Californica Benth. Stems terete; the upper part of the stem closely set
with subsessile glands. Only a few plants seen and mostly out of bloom and
dry. On stony ridges. Santa Rosalia, February 24 to March 3. No. 180.
The same. In sandy spots in stony ravines. ‘ Bloom, crimson-colored.”
Santa Rosalia, February 24 to March 3. No. 196.

82

Fagonia Palmeri n. sp. Stout perennial, woody at base, 1 to 14 feet high, more or
less glandular pubescent: leaves opposite, digitate ; leaflets 5 to 7, linear, with
spiny tips, 4 to 5 lines long; stipules long erect spines: petals 4 lines long,
deep rose color.—Santa Rosalia, February 24 to March 3.

This species very much resembles F. Californica in fruit and flowers, but of
very different habit, leaves, and upright stipules; and in its 5 leaflets differs
from all the other described species of this genus. Dr, Palmer says of it:
grows in a bunch from several stems 1 to 1} feet high, the lower ones often
lie on the ground. Itis very spiny. The leaves, especially upon the lower
two-thirds of the plant, have a decided golden hue, which is very noticeable
ata distance. No. 209.

RHAMNACES.

Colubrina glabra Watson. Proc. Amer. Acad. XXIV. 44. The plant is much larger
than the one from Guaymas. It is here a small tree or bush 5 to 12 feet
high, scrubby in character. The branches are often slender and pendant. Dr.
Palmer thinks this is owing to the soil and moisture, for in dry and stony places
they are short and straight. Only a single plant found in flower, and they of a
yellowish-green color. It is very common in stony gulches. Santa Rosalia,
March 15. No. 267.

SAPINDACES.

Paullinia (?) sp. Climbing or trailing over bushes: leaves 3-foliolate: flowers in small
clusters: petals 4: stamens & Agueda, March 4106. Most of the leaves had
fallen ; the remaining ones closely resemble B. Sonore. The fruit (immature) is
different and is apparently tuberculate. Only 3 plantsseen in a sandy gulch at,
Santa Agueda, March 4 to 6. No. 263.

LEGUMINOS 4).

got at Santa Maria. Common in low, sandy places, growing about 3 feet high.
It yields a yellow dye. Santa Rosalia, February 24 to March 13. No. 179.

Dalea megacarpa Watson. Proc. Amer, Acad. XXI. 359. A large bushy plant 2}
feet high; flowers yellow, with an agreeable honey-like odor. Common in ar-
royos. Santa Rosalia, February 24 to March 5. No. 182.

Tephrosia Purisime Brandegee. Proc. Cal. Acad. 2nd ser. II, 149. Hardly
distinguishable from 7. Palmeri except in the purple flowers. It was about
past flowering March 1, when Dr. Palmer visited this region. 1t grows sparsely
in a cafion near Santa Rosalia. No. 198.

Parkinsonia microphylla Torr. Called ‘‘Lebon” (?) Dr. Palmer says the young
branches are much relished by domestic animals and are largely gathered by
the natives for this purpose. No. 265.

Cassia Covesii Gray. Branching at base, 3 to 5 feet high; a free bloomer. The pods
about 8 in a compact cluster. The stipules are longer than described, being
5 to6 lines long. The pubescence isof a yellowish hue. Dr. Palmer says it
differs from the Guaymas form and in appearance is somewhat different from
our herbarium specimens. Palmer’s Los Angelos plant (557 of 1887) is the same
as thisone. Santa Rosalia, March 5. No. 192.

83

Pithecolobium, sp. A large tree growing near water, with a trunk 5 feet long and
8 iuches in diameter, with an immense top out of all proportion to the trunk,
and a great profusion of yellow, rather sweet-scented, flowers. A useful wood.
The flowers in capitate clusters on peduncles 1 to2 inches long. The numerous
short stamens are united into a very short tube; the ovary on a stipe of twice
its length, The generic position of this species is doubtful, but its connate
stamens forming a tube places it in Bentham’s section Ingew. Santa Agueda,
March 4 to 6. No, 261.

form, 9 to 12 lines long; stipules small, with 1 or 2 sete: pedicels 2 to 3 lines
long or wanting: calyx in flower 1 line long; in fruit 2 lines long, with 4 acute
divisions: corolla pink, with slender tube 3 lines long, and lobes 2 lines long :
capsules globular, about one-third free from the calyx, about 40 seeded.—Only
a single specimen collected near Santa Rosalia, in a cafion, February 24 to

the edge of ditches in a garden, Santa Agueda, March 4 to 6. No. 248.

Perityle Emoryi Torr. Santa Rosalia, March 4 to 6. No. 184.

Perityle deltoidea Watson. Collected growing with P. Emoryi. No, 185.

Perityle aurea Rose n. sp. About 10 inches high, much branched and spreading, some-
what pubescent and glandular: lower leaves broader than long, an inch broad, ir-
regularly lobed and serrate ; upper leaves becoming very small: rays yellow : disk
corolla with slender tube abruptly passing into the swollen tubular companu-
late throat: style broader, slender, with slender acuminate appendages: akenes
small (a line long), linear and straight, with ciliate margins: the pappus of a
crown of united squamelle with fimbriate edge and a short awn.—Santa Rosalia,
February 24 to March 3.

It resembles P. Emoryi most in habit and akenes, but its yellow rays, more
swollen corolla throat, slenderer, less granular corolla tube and style tips
keep it out of this species. It grows with 1’. deltoidea, but of different habit,
leaves, style tips, etc. No. 185°.

Perityle Fitchii Torr. Only a single plant seen; this under an overhanging rock at
the outer edge of a garden. This plant is evidently taller than the species has
been described, as branches which Dr. Palmer has collected are 15 or more
inches long; many of the leaves opposite. Santa Agueda, March 4 to 6.
No. 247.

Porophyllum crassifolium Watson. Proc, Amer. Acad. XXIV. 57. The plant is
deep-green, which attracts attention; as the few associated plants are now
dry and dead. The leaves are very fleshy and the plant has a strong aroma
of the cultivated Rwe. Grows in cafions near the sea. Santa Rosalia, Febru-
ary 24 to March 3. No. 177.

Bebbia juncea Greene. The leaves are not entire, but strongly toothed or lobed.
The involucral bracts are very short and ovate. Santa Agueda, March 4 to 6.

A careful comparison of the type specimens as found in the Gray Herbarium
of Pringleophytum lanceolatum and B. virgata convinces us that they are the
same species. Mr. Brandegee, in his paper on the plants from Baja California,
suggested that the two were probably the same. No, 272.

GRAMINES.

Paspalum distichum L. This plant grows upon alkali soil along water ditches, and
even in the water; much alkali causes the rnnners to become reddish. It grows
freely where sugar cane is raised, if not destroyed by cultivation; most of the
specimens were from an unfavorable situation. Commonly called ‘‘Gramma.”
Is is considered of value as a medicinal plant, being used for kidney troubles
and gonorrhea. WNo. 214.

Panicum sanguinale L. Found upon the top of the embankment to a water ditch;
only a few plants seen. No. 222.

Panicum colonum L. Found ina field where sugar cane had been raised at some
past time, and which was being replanted. No. 223.

216.

Phragmites communis Trin. ‘‘ Near the water the cane grows from 20 to 25 feet
high, the lower part being very slender for the height, as the specimens show.
Dowestic animals devour it. It is used for various purposes by the natives.
They cut it to certain lengths, and having split it, beat it flat and then weave
it in and out, making a large square mat, with which they form sides or ends of
the houses; they place it over the rafters before the tule thatch is put on;
they use it to cover verandas, and also for screens for doors.” No. 211.

Eragrostis major Host. Found in garden, The only specimens seen. No. 215.

Eragrostis Purshii Schrad. Common among alfalfa; but few of the plants were in
good condition. No. 218.

Distichlis maritima (?) form. ‘‘Grows in thick masses in wet alkali soils; saw much
that was cut to feed animals, which was twice the size of these specimens, but
they had no flowers or seed ; these were the best to be had; found on a dry
spot on the outer edge of a garden.” Wo. 219.

PLANTS COLLECTED AT GUAYMAS.

The plants collected at Guaymas were obtained at several different
times. No very extensive collection was made at this time, as this re-
gion was so thoroughly examined in 1887; yet in spite of this former
almost exhaustive collection this region still yields some new species
and others of great interest. Of this latter class is to be mentioned
Prosopis heterophylla Bentham, now for the first time obtained in flower,
and Spheralcea Coulteri Gray.

Spheeraicea Coulteri Gray.' A little annual 2 to 6 inches high, growing scatteringly
among other small plants on sandy plains near Guaymas, The flowers are

small but quite showy, of “bright amber color,” but in dried specimens rose-
colored. The specimens are not in fruit, but Dr. Watson has kindly sent me

4 Dr, Palmer has since sent fruiting specimens of this species, leaving no doubt as
to <ts identity.

88

the specimens of these species in the Gray Herb., and it is clearly the same 8.
Coulteri. It ditfers widely from all other Sphe@ralcee in habit as well as carpels.
The locality at which Coulter collected this species is doubtful, and it is
as probable he got it at Guaymas as in either California or Arizona, February 13
to1l7. No, 171.

Zizyphus obtusifolia Gray. A loose-growing, thorny shrub, generally found in
mesquit thickets; fruit black. February 15 tu 17. No. 162.

Sapindus marginatus Willd. In cultivation at Guaymas. No. 176.

Cesalpinia Palmeri Watson. Proc. Amer. Acad. XXIV. 47. Dr. Palmer says:

Abundant plant, blooming now (February 11) with as much freedom as it
does in the rainy season. No. 70 of 1887 collection, No, 146.

Coursetia glandulosa Gray. In ourremarks on this species from La Paz, p. 68, we
mentioned that C. microphylla should probably be referred to this species. A care-
ful examination of a large supply of material from Guaymas convinces us that
the two species are the same. C. glandulosa was collected by Xantus from the
extreme point of Lower California in flower, with merely the old leaves remain
ing. C. microphylla came from Pringle’s Arizonian collection, and is somewhat
more advanced with the small leaves, buithe older and larger ones gone. The
leaflets of this species are very variable, and the two forms are sometimes to
be found on the same specimens. In most of the specimens sent the leaflets
are as in C. microphylla, small (1 to 3 lines), Jong sericeous pubescent, while on
the saine plant we find the large (7 lines long by 3 to 4 lines broad) almost glab-
rous leaflets of the original C. glandulosa: the flowers are white, becoming rose-

-colored. A very common shrub in gravelly arroyos about Guaymas. It is 4 to
6 feet high, with several stems from the base and somewhat spreading. A very
profuse bloomer. February 15 to 17. Itseems also to have been collected here
by Palmer without flowers or fruit in 1887, but not reported by Mr. Watson.
No. 163.

Parkinsonia Torreyana Watson. About 15 feet high with large top: flowers yellow.
Dr. Palmer says that as the flowers open the leaves fall and the plant remains
without leaves until the seeds are mature. No. 275.

Acacia Willardiana Rose.’ A slender tree, 10 to 15 feet high, with few drooping
branches, glabrous, and without spines of any kind: leaves with minute, de-
ciduous stipules; petioles phyllodia-like, 3 to 12 inches long by 1 line broad,
either naked or with mostly 1, sometimes 2, and rarely 4 pairs of pinne at the
tip; leaflets where present 4 to 5 pairs, sometimes 12 to 15, somewhat fleshy,
indistinctly 1 to 2 nerved, 1 to 2} lines long, abruptly acute, glabrous or minutely
pilose, as also the petioles and younger parts of the stem: the inflorescence a
panicle of slender spikes terminating the slender branches: spikes 2 inches long;
flowers yellow: calyx companulate, about a line long, with 5 broad obtuse
teeth: petals a little longer, distinct to the base, oblong to cuneate oblong,
obtuse or abruptly acute: stamens 140 to 150. ‘‘Legumen planum, rectum,

of September 10, 1890, inclosing two mature legumes of this species, which now for
the first time have been collected, and may be described as follows: ,

Legume glabrous, oblong to linear-oblong, 2 to 4 inches long, 5 to 7 lines broad, ob-
tuse at tip, cuneate at base, extending into the short stipe; some constricted, others
not at all, membranaceous, with delicate irregular reticulations; seeds brownish,
oval to oblong, 4 to 5 lines long.

The numerous filaments are still present in these mature specimens, forming a white
fringe surrounding the stipe, and it isa little strange that they had not been observed
by Benthan, who had the immature legumes,

Only two mature legumes were found, all the others having been killed by the hot
winds of June. Dr. Palmer says ‘‘ this was confirmed by my own observation, for an
entire day was spent among Acacia JVillardiana and I only found two pods.”

Hab. ‘Sonora alta in Mexico, Coulter ;’ Guaymas, Palmer (No. 628), 1887,
and now from the “rocky islands and ledges on the coast of Guaymas har-
bor.”

The collection of this plant in flower for the first time enables us to de-
cide its generic position. It was collected by Dr. Thomas Coulter fifty or more
years ago, but only in fruit, and there is apparently but a single specimen in
existence, which is in the herbarium of Trinity College, Dublin. It was found
by Mr. Bentham when on a visit to this herbarium, and was described by him
in 1846 in the Lond. Jour, Bot. as a new species of Prosopis. It was doubttully
referred here, however, and its possible reference to Acacia was mentioned.
Palmer’s specimen of 1887 was without flower or fruit, and Mr. Watson could
dono more than identify itas Bentham’s species, Although in habit the species
of the two genera are similar, with the flowers the two are readily and clearly
separated, Prosopis having always ten stamens, while in Acacia they are numer-
ous, and in ours decidedly so, being 140 to 150. There are several little points
of difference between Bentham’s description and our plant,which should be
noted here,but the general characters are so clear as to leave no doubt as to
the identity of the two plants. Bentham says ‘‘stipule obsoletw,” while we
find small but deciduous stipules; also “ pinne 2, rarius 4,” whilein none of
our specimens do we find more than one pair; again ‘foliola 12 to 15 juga,”
while ours are mostly 4 to 6, a few are 10 to 15, The young branches are white, as
mentioned by Bentham, but in age become a grey or reddish brown. Unfor-
tunately a new name must be coined for the species, A. heterophylla having
long before (1805) been used by Willdenow; neither can it be named for either
of the collectors, Coulter or Palmer, as they both have species named for them
in the genus; nor for Mr. Bentham, who, although not so fortunate, is repre-
sented in the synonomy of this genus. At the request of Dr. Palmer we have
named this species for Mr, Alex, Willard, United States consul at Guaymas,
Mexico, who has given every aid possible to him on his several visits at that
place. No. 164.

Cereus pecten-aboriginum Engelm. in Watson, Proc. Amer. Acad. XXI. 429. The
flowers of this species are collected now for the first time, and the following
additional characters are supplementary to the description found in Mr. Watson’s
paper referred to above.

Flowers 2 to 3 inches long: ovary closely covered with dense soft hair, with-
out spines or rarely a few: sepals purplish, succulent: petals white, fleshy :
stamens very numerous: style with ten linear stigmas with spiny tips.

The plants grow 30 feet high and a foot or more in diameter, with many
branches. The fruit is formed at or near the top. No. 274.

Hofmeisteria crassifolia Watson. Proc. Amer. Acad. XXIV. 53. Found on an
island in the harbor at Guaymas, growing near the water. Very sweet scented.
No. 165.

Hymenatherum coccineum Gray. The type collected by Pringle at Tucson, Arizona,
(1884), and we believe not since obtained. Dr. Palmer finds it very common
on a sandy, gravelly plain, in exposed places. It hasastrong odor. February
15 to 17, near Guaymas. No. 168.

Pectis Coulteri Gray. Found in sandy, gravelly plains near Guaymas, February
i5 to 17. No. 173.

Cordia Watsoni Rose, n. sp. Besides the differences given by Mr. Watson, the fol-
lowing characters furnished by the mature fruit clearly set this off from C.
Greggii: The fruiting calyx of different shape, almost globose (4 to 5 lines in di-
ameter) and not closely inclosing the fruit, but loosely and somewhat inflated :
pubescent instead of strigose: the fruit much larger, with thick, bony walls in-
stead of thin crustaceous.

Cordia Greggit Torr., var. Palmeri Watson. Proc. Amer. Acad. XXIV. 61.

Mr. Watson’s varietal name can not be used, as it has already been given to
another species. We take pleasure in dedicating this species to him, as he
has partially pointed out the difference from C. Greggii, and I have no doubt
would have separated it at the time had the fruiting material been at hand.
No. 174.

Krynitzkia, sp. Guaymas, February 15 to 17. No. 169.

Phacelia scariosa Brandegee. A few plants found on the edge of an island, February
1b t0 17. No. 146. ;

Nama demissum Gray. Common on gravelly plains about Guaymas, February 15
to 17. No. 172.

Gilia (Bugilia) Sonorz Rose, n. sp. A small annual, 1 to3 inches high, branching
and somewhat spreading, puberulent throughout: leaves alternate, pinnate};
segments linear, acute: calyx 2 lines long; sepals green, connecved by scar-
rous margins } their length: corolla of the same length or a little longer, but
slightly spreading, whits, with a pinkish tinge : stamens included, inserted very
near the base of corolla: capsule 2 lines long, seeds 16 to 18 in the cell.
Grows in great profusion on sandy plains near Guaymas. Perhaps nearest G.
companulata Gray. February 15 to 17, No, 170.

‘Cryptocarpus (?) capitatus Watson. Proc. Amer. Acad. XXIV. 71. No. 175.

Amarantus Palmeri Watson. Proc. Amer. Acad. XXIV.71. Some very small forms
collected in a garden near Guaymas, February 11. No. 147.

Eragrostis Purshii Schrad. Growing near water-ditch. Guaymas, February 11.
No. 145.

Aristida bromoides H. B. K. No. 273.

No. 167. This is 179 of Palmer’s collection, also obtained by Xantus and Brandegee.

Its generic position is not known.

The leaves are narrowly to broadly linear, 3 to 5 inches long, 2 to 6 lines
broad: fruit round and black.

Dr. Palmer says the tree sheds its leaves just as it is ready to bloom; the
young ones appear at the ends of the branches as the flowers expand, and are
full grown when the fruit isripe. At first’ he was of the opinion that the shed-
ding of the leaves was caused by the trees growing in dry, rocky places, with
little or no soil, as these being in full bloom (probably brought on by the heavy
rains which had fallen a few weeks before), while those in deep soil were in
full leaf and had yet not shown even a flower bud. He visited Guaymas a
month afterward (March 15) and found the trees growing in deeper soil were
then in bloom and had just dropped their leaves also; he believes, therefore,
that the falling of the old leaves at blooming is a natural character.

It is surprising that a tree of such size and of such wide distribution has for
so long been and still remains unknown to botanists. A letter from Dr. Palmer
of recent date (September 1Uth) states that he has been unable to get fruit of
this plant, the dry hot wind of June having killed the young fruit.

LIST OF PLANTS COLLECTED BY DR. EDWARD PALMER IN
WESTERN MEXICO AND ARIZONA IN 1890.

By J. N. Ross.

The plants upon which this report is based were collected by Dr.
Palmer, in 1890, in Mexico and Arizona. Dr. Palmer returned to
Guaymas March 18, after finishing his collection at Santa Rosalia;!
from this place he went to Alamos, remaining three weeks, and then
returned to Guaymas; from here he proceeded to Arizona, staying
three months, and then went to San Francisco and remained until
August 23, when he again left for the Gulf of California, expecting to
land at Carmen Island, but owing to some regulations of the custom
officials of Mexico he was carried to Guaymas. He was planning
again to visit Carmen Island,? when an opportunity offered to return
to Alamos, and as he was desirous of getting the summer as well as
the winter flora, he postponed the trip to Carmen Island and embarked
by steamer for Agiabampo, the seaport of Alamos. This second trip to
Alamos lasted two weeks, and was very successful, notwithstanding it
was interrupted by a severe attack of intermittent fever, which com-
pelled him to return to the seacoast.

The total number of new species collected by Dr. Palmer and reported
in this paper is 45, with several new varieties.

The following table will show the places visited, with the date of col-
lection and the number of plants:

*It will interest those who have been following Dr. Palmer in his valuable work in
lower California and Mexico, to know that he has since visited Carmen Island and
made large collections at Agiabampo and in the State of Colima, which will be re-
ported upon in a future number of these contributions.

I wish to express here my thanks to Dr. George Vasey, Botanist of
the Agricultural Department, under whose direction this report has
been prepared, and whose ready familiarity with North American
plants has been a great source of help; to Dr. Sereno Watson and his
assistant, Dr. B. F. Robinson, for courtesies shown me while at Gray
Herbarium ; to Mr. Wm. M. Canby for the generous loaning of many
plants, and for aid in difficult determinations ; and to varions special-
ists, both at home and abroad, who have given help in their separate
lines, which is credited in the proper place in the text,

PLANTS COLLECTED AT ALAMOS.

Alamos or Los Alamos is a mining town of about 10,000 inhabitants, sit.
uated 180 miles southeast from Guaymas. Its altitude is 1,275 feet above
sea level. Two visits were made here, one in the dry season, March 26
to April8; the other during the rainy season, September 16 to 30. The
flora of the two seasons is very different, and only 8 or 10 species
are duplicated in the two collections. The collection in the spring
yielded about 130 species (Nos. 276 to 414); of these, 18 are new. The
fall collection contained about 120 species, 25 of which are new. The
following interesting facts are gathered from Dr. Palmer’s notes. The
beginning and ending of the rainy season varies somewhat; generally it
commencesin July and lasts until the first week of October. After the
first good rains vegetation springs up as by magic, grows rapidly, then
disappears nearly as quickly as it came; it is at its best in August.
The soil is mostly poor and rocky except in the valley.

While at Alamos, Dr. Palmer visited the Alamos Sierra or Sierra de
los Alamos, a mountain 6 miles due south of the town of Alamos. Of
the 75 species collected here 13 were indeterminable; of the 62 remain-
ing ones 18, or more than one-fourth, are new. The total number of
species collected at Alamos and vicinity was 263, of which 36 were inde-
terminable!, and of the 227remaining 43 are new. Among the plants of
this collection are many very beautiful ones which should claim the at-
tention of cultivators. Of these we cite: Heteropterys Portillana, a
recent species described by Mr. Watson. This is especially attractive ~
for its large clusters of red fruit. It is very common at Alamos and
could easily be obtained for cultivation.

Galphimia Humboldtiana, a rare plant in herbaria, is a common and
attractive shrub of the mountains here. It is 6 to 8 feet high, with a
handsome top,large racemes of yellow flowers, and attractive foliage.

Cordia Sonore is a new species, a very beautiful shrub or small tree,
and an abundant bloomer.

1 It is proper to state here that the reason so many of these plants are not deter-
mined is because Dr. Palmer collected a number in the dry season, which were not in

Tababouia Palmeri, another new species, is a conspicuous tree of this
region. It grows to the height of 25 feet and produces large clusters of
flowers.

Three or four of the Ipomceas are very attractive; one is a tree 30
feet high ; another is a climbing shrub (J. bracteata) with large conspic-
uous bracts which give the plant a very showy appearance; two other
new species are high climbing vines.

Clematis Drummondii T. and G. Very common, climbing over trees, bushes, and
fences along water courses at Alamos. March 26 to April 8. No. 294,

Sisymbrium, sp. A little annual 3 to 5 inches high, with the foliage of S. canescens,

Echinopterys Lappula Juss. The leaves of this plant are quite variable, sometimes
obtuse, again the upper ones acuminate. This is the same as Palmer’s Guaymas
(1887) plant referred here by Watson, differing only slightly from his description.
Our plant differs considerably in habit, being a climbing shrub covering the tops
of surrounding bushes. Alamos, No. 404.

Galphimia Humboldtiana Benth. Dr. Palmer says: “It is the most beautiful
plant of the mountain, forming a conspicuous object along the arroyos, It grows
6 to 8 feet high with one or more stems and a compact top of numerous racemes
of bright yellow flowers as if polished, changing by age to light brown; this
double coloring of the flowers contrasts strongly with the dark green of the leaves
and gives it a just claim for cultivation.” Mountains about Alamos. March 20
to April 8. No, 284,

‘Heteropterys Portillana Watson, Proc. Amer. Acad. xx1. 402, This species was
described from flowering specimens only, and as both flowers and fruit are now
at hand additional characters are here appended. Flower buds pink to rose-col-
ored : styles 3: sémara puberulent, 1 to 3 mostly 2, rarely 3, With several lateral
crests; the dorsal wing 9 lines long. Dr. Palmer says the fruit, which is of a
shiny brick-red color, grows in large masses, making it very attractive, and he
considers it a valuable plant for cultivation. A very common plant about Alamos
growing over brush and bushes especially along water-courses and in canons.
September 16 to 30. No. 655 in flower and No. 656 in fruit. The only other time
it has been collected was by Dr. Palmer at Baranca, Jalisco, in 1886.

(fruit). Collected also in fruit, March 25 to April 8. No. 323.

Serjania Mexicana Willd. A climbing plant with long slender stems with seat-
tered short prickles: flowers sweet-scented, white, in racemes 3 to 4 inches long.
Dr, Palmer says the Mexicans use the stem to tie wood, grass, etc., into bundles,
its strength and pliability making it very applicable for such purposes. It is
called ‘*quirote culebra.” Alamos. March 26 to April 8, No. 383.

‘Vitis Arizonica Engelm. Probably this species. Only collected in flower. The
fruit is said to be of no value. Only two plants seen. Found climbing over
rocks, along a water-course, half way up the Alamos Mountain, March 26 to
April 8. No, 296,

-Rhus Palmeri, n. sp. Large shrub or small tree, 5 inches in diameter, 6 to 15 feet
high, with large loosely-hanging top; branches puberulent: leaves pinnate;
rhachis not winged; leaflets5 to 13 mostly 9 to 11, elliptical-oblong, 1} to 2 inches
long, acute, mucronate-tipped, appressed, pubescent: panicle terminal, 3 to 5
inches long: flowers unknown: berries glabrous, red, 3 to 5 lines in diameter,
acid, very viscid.—Along a water-course half way up the Alamos Mountain,
March 26 to April 8. No, 321. Although not in flower this is evidently a Rhus
-and seemingly nearest R. juglandifolia Willd. of Southern Mexico, but the leaf-
-lets are smaller and pubescent.

Crotalaria ovalis Pursh. Alamos. September 16 to 30. No. 712.

Indigofera Anil L. This is a small plant 1 to 14 feet high with dark bronze colored

Hosackia Alamosana,! n. sp. Procumbent, rooting at the joints, glabrous or the
younger parts with appressed hairs: leaves 3 to 5-pinnate; stipules 1 to 2 lines
long, foliaceous, ovate, acute; leaflets obovate, obtuse, 2 to 5 lines long:
peduncles slender, 2 to 4 inches long, 1 to 4-flowered, mostly 2: bracts 1, seta-
ceous: flowers small 2 to 3 lines long: calyx tube less than a line long; its lobes
almost as long and very narrow: corolla yellow: pods 10 to 15 lines long, terete,
erect, 12 to 15-seeded; seeds turgid, oblong, lucid.—Half way up the mountain
ina wet spot. Alamos. March 26to April 8. No. 400. Dr. Palmer says: ‘‘ The
plant roots at every joint and forms a thick sod.” The plant is nearest H. angus-
tifolia of Mexico, but differs from it especially in its procumbent habit; its fewer
and obtuse leaflets; smaller flowers and bracts. It is questionable, whether
Seemann’s (No, 121 of Botany Herald) broader leaved form from this same range
of mountains may not really be our plant. Mr. Hemsley (Biol. Cent.-Amer. I.
234),who has probably seen Seemann’s plant, however, kept it as a possible
variety of H. angustifolia and refers to it Parry and Palmer’s No. 140, which is a
very different plant from ours.

It differs from H. repens Don. (which species Mr. Hemsley has omitted in the Biol.
Cent.-Amer.) in its fewer leaflets (1 to 3 pairs),and these not mucronulate; heads
fewer flowered (mostly 2, rarely 4); and glabrous calyx.

from view in the grass. Flowers white at first, becoming pinkish when drying.

Dalea levigata Gray.(?) Four to five feet high, without leaves: flowers white.
Very common in the mountain. Dr, Palmer says that the branches are made
into brooms by the Mexicans and sold in the markets at Alamos. March 25 to
April 8. No. 853.

Dalea Parryi Torr. and Gray. A loose growing plant about 3 feet high. Common on
hillsides about Alamos. September 16 to 30. No. 739.

Brongniartia podalyrioides H.B.K. A shrub 8 to 10 feet high, 3 to 4 inches in
diameter: leaflets5 to 7 pairs. Alamos. September 16 to 30. No. 658.

It differs from B. galegoides, which it resembles somewhat in the flowers being
axillary not racemose; the leaflets larger, with cuneate base.

Brongniartia Palmeri,n.sp. Shrub, 1} to 2} feet high, glabrous; branches villous-
pubescent: leaves 2 to 3 inches long; stipules large, 6 to 8 lines long, ovate;
leaflets 6 to 8 pairs, oblong, appendiculate, glabrous above, with villous hairs
along the margins and midrib below: inflorescence in a terminal raceme ; flowers
mostly 3 to5 in the axils of stipular bracts: peduncles 9 lines long, enlarged
below the calyx: calyx 6 lines long; its two upper lobes high connate: petals
purplish: pods 14 to 2} inches long, glabrous and glaucous, oblong, tapering at
base, 3 to 6-seeded: seeds 3 to 4 lines long.—Rare, only a few plants seen near
the base of the mountain. Alamos, March 26 to April 8, No. 300. In B. galegoides
the upper bracts are small, leaflets larger, ete.

Diphysa racemosa, n.sp. Five to ten feet high, the younger parts, foliage and in-
florescence, very viscid, granular: leaflets 9 to 17, oblong, small, 3 lines or more
long: racemes axillary 8 inches or more long: pedicels 4 lines long: 2 bractlets
at base of flowers, oval, 3 lines long: calyx about 6 lines long, the slender tube
below the disk 2 lines long: legume on a stipe 6 lines long, oblong, 14 inches
long, # inch broad.—Hill-slopes, in deep soil near Alamos. March 26 to April 8.
No. 295. The wood is very hard and yellowish, covered with a dark-brown bark
abundantly spotted with many horizontal lenticles. This is both in flower and
fruit. It is almost gummy and emits a most disagreeable odor.

EXPLANATION OF PLATE III.—Shows racemes and foliage; a, legume; b, section of stem with

lenticles. All natural size.

Coursetia glandulosa Gray. A large scraggy bush with severalstems. The stems
are often covered with a thick coating of gum, Dr. Palmer says it has great
medical value. The gum dissolved in water with sugar is used as a drink in
cases of colds and fevers, and as a remedy for consumption it is highly extolled.
It is sold in the drug stores at a dollar per pound, under the name of ‘‘ Guma So-
nora.” The plant is known as ‘‘Samo prieto.” It grows at the base of the
mountains in the gulleys. Alamos. March 26 to April 8. No, 333.

Willardia, n. gen. Calyx truncate with small equal teeth. Petals equal; vexillum
orbicular spreading; wings falcate-oblong ; keel slightly incurved. Vexillary
stamen connate into a tube with the others except at base; anthers uniform.
Ovary sub-sessile with several ovules; style incurved, glabrous or with a few
hairs at base; stigma capitate, minute. Legume linear-oblong, strongly com-
pressed, continuous within: seeds reniform, strongly compressed. A small tree:
leaves imparipinnate; leaflets definite, entire, exstipellate. Stipules obsolete.
Racemes axillary. Flowers “lilac.”

This plant was first named and described as a Coursetia by Dr. Watson, to
which genus it is closely related. The type specimens, however, were only in
fruit and it was doubtfully referred as above. The collection by Dr. Palmer of
an abundance of flowers shows a still greater divergence and demands the estab-
lishment of a new genus.

It differs from Coursetia especially in its truncate calyx and glabrous style.
Its position, however (according to Dr. P. Taubert!), seems nearest Lennea, from
which it differs in its style and more membranaceous pod.

It resembles Sabinea in its calyx but differsin having racemes of flowers, and
also from this as well as all the other Robiniew except the above two, in its con-
nate stamens.

At the request of Dr. Edward Palmer I have named this genus for his old
and valued friend, Hon. Alexander Willard, who for twenty-five years has rep-
resented our Government as consul at Guaymas, and has aided Dr. Palmer with
his various collections from this region.

1] am under many obligations to Dr. P. Taubert, of Berlin, who is preparing and
will soon issue the Leguminose in Die Natiirlichen Pflanzenfamilien, for confirming
my observations and adding new information.

Willardia Mexicana. Small trees 10 to 30 feet high, very straight, with smooth
bark and 1 foot or more in diameter: leaves (only a few of the old ones remain-
ing) 4 to 7 pairs, oblong-elliptical, obtuse at each end or subemarginate, 8 to 15
lines long, 6 to 8 lines broad, finely and softly pubescent, especially beneath:
racemes somewhat paniculate many-flowered:! calyx 2 lineslong with very short
teeth: petals 5 lines long: stamen tube truncate at apex: ovules 8 to 10, pods
very thin, narrowed at each end, 2 to 5 inches long, 4 to 6 lines wide, more or less
constricted, dehiscent: seeds 5 lines long, smooth and shining, pale salmon color.
—In flower March 25 to April 8 (No. 332), in fruit September 16 to 30 (No. 717).
Also collected in SW. Chihuahua in 1884 by Palmer. Coursetia (?) Mexicana

Called ‘‘Nesco ” or * polo piojo.”

Common in the Alamos Mountain, where it is much used by the miners for
‘‘props.” Only two trees seen near the base of the mountain. The trees near
the settlements are mostly destroyed.

Desmodium plicatum Schl. and Ch. The plant has two or three slender stems and
a few loose, hanging branches: racemes axillary or terminal, 6 to 8 inches long:
flowers in verticillate clusters, crimson, becoming dark purple when dry. On the
side of a ravine in the upper portion of the Alamos Mountain. March 26 to
April 8. No. 347. Wehave not seen a description of this plant, but it corresponds
with Bourgeau’s plant referred here by Hemsley.

Rhynchosia precatoria DC. (?) This plant seems to belong to this species and to
be different from 2. phaseoloides, to which it is often referred by authors. The
latter species can be distinguished by its glabrous shining pods and large flowers.
Several very similar forms have been referred to R. phaseoloides by Mr. Watson,
and while the two, as represented in the National Museum, seem distinct, a
fuller representation may show they are the same species. Along a river bank
near Alamos: March 26 to April 8. No. 378. |

Eriosema grandiflorum Seem. About 1 foot high. Only a single plant seen. At
the base of the Alamos Mountain. March 26 to April 8. No. 360.

Nissolia Schottii Gray. <A climbing shrub, glabrous, leaves alternate; leaflets 5,
thin, oblong to obovate (6 to 10 lines long), obtuse with appendiculate tip: flowers
axillary, 2 to 5(?) in a cluster: fruit 10 lines long, 1 to 2-seeded. This shrub was
found climbing over fences, etc., about Alamos. September 16 to 30. No. 638.

Piscidia mollis, n.sp. Apparently asecond species of this genus. A tree 15 to 25 feet
high, a foot in diameter: leaves 11 to 13 pinnate; leaflets elliptical or broad
lanceolate, acute, hoary, veins prominent beneath, indistinct above: fruit 4-
winged, 2 somewhat abortive.—Common on ridges and plains about Alamos
March 26 to April8. No. 355. Called ‘‘ palo blanco,” from the excessively white
appearance of the tree.

Parkinsonia aculeata L. Called “Guacoporo.” A shrub 10 to 15 feet high. Com-
mon along river banks, ravines, etc. Alamos. March 26 to April 8. No. 375.

Cassia Tora L. One of the commonest plants of the region and found everywhere
in waste places, especially in sandy soil. Alamos. September 16 to 30. No. 738.

Cassia biflora L. One to one and a half feet high. Grows on wooded hills about
Alamos. March 26 to April 8. No. 393. September 16 to 30. Letter B.

Cassia emarginata L. A small tree 10 to 15 feet high, with a very large top. The
abundance of orange-colored flowers makes it an attractive tree, This is the
same as Palmer’s No. 210, Chihuahua, 1885, Near Alamos. March 26 to April
8. No. 299.

1All the flowers were more or less infested by a little encysted insect which Mr. L.
O. Howard has described as a new genus Tanaostigma. For a description and an
interesting account of this insect see Insect Life, vol. 11.

Mimosa (Leptostachyae) Palmeri, n. sp. Large, bushy shrub, 8 to 10 feet high,
thornless or with a few infra-stipular spines; the younger branches fuscous-
pubescent: leaves large, with setaceous stipules; rhachis 4 to 8 inches long,
deeply grooved; pinne with small stipels, 6 to 16 pairs, oblong-oblique 14 to 24
lines long, appressed pubescent above and below: spikes (2 to 4 inches long)
axillary or racemose, corolla pinkish, its lobes pubescent and spreading: stamens
10: ovary with reddish-brown pubescence, tipped with a long, slender style.—
This shrub was only found in flower, and these mostly in terminal racemes 6 to 8
inches long. The buds and flowers are pink and very showy and sweet-scented.
Near Alamos. September 16 to 30. No. 628. This plant comes nearest to M.
Wrightii, but with larger and more open leaves and with different pubescence.

Acacia pennatula Benth. In these specimens the peduncles are very short (3 to
6 lines long), while those of Pringle from Jalisco (1889), referred here by Mr.
Watson, have peduncles sometimes 14 inches long. No fruit accompanies these
specimens. Commonly called ‘‘Algaroba.” It is a small tree with a very broad
top. The flowers are very numerous, orange-colored, and very fragrant.

Acacia malacophylla Benth. var. microphylla Watson. Our plant seems to be the
same as Pringle’s Sonoran specimens collected in 1884. We have not seen Mr.
Watson’s description of this variety. Dr. Palmer says it is a small tree resem-
bling the mesquit. Itis nearly exterminated; about settlements it is much used
for fuel. Near Alamos. March 26 to April & No. 315.

Acacia (7?) sp. A large bushy shrub with several stems, 8 to 10 feet high, with a
large top, somewhat thorny: pinne 4 to 8 pairs; leaflets 8 to 10 pairs, oblong, 2
to 3 lines long: heads on peduncles 4 inch long: pods with 6 to 10 deep constric-
tions, margin thick and breaking away from the valves. Alamos, September 16
to 30. No. 627. This shrub is probably of this genus, but as it is only in fruit
its generic position is doubtful. The pods seem to ally it with 4. constricta.

Leuczena lanceolata Watson., Proc. Amer, Acad, Xx. 427. A large bushy shrub 8
to 10 feet high, glabrous or nearly so throughout: pinnae 4 to 6 pairs with a small
gland between or at the base of the upper pair; leaflets 3 to 6, glabrate or nearly
so: pods erect, 6 inches long tapering at base intoa stipe (6 to8 lines long) gla-
brous, marked with cross partitions. LZ. lanceolata was described from flowering
specimens and ours is in fruit. It seems nearest that species but differs from the
description in most of the above particulars and lacks the large gland on the
petioles. In acafion near Alamos. September 16 to 30. No. 718.

Lysiloma Watsoni, n. sp. A small tree 10 feet high, 3 inches in diameter; branches,
rhachis and leaflets densely cinereous-pubescent: leaves large; rhachis 5 to 6
inches long; pinn 8, 2 to 5 inches long; leaflets 30 to 45, thick, oblong, 2 to 4
lines long, obtuse, with midrib somewhat excentric: legumes single or two or
three in a cluster, oblong, 5 to 8 inches long, 10 to 12 lines broad, tapering at
base into a stipe, 6 to 12 lines long and abruptly narrowing into a spiny tip 6
lines long ; the exocarp first breaks away from the persistent margin: seeds ob-
long-oval, 44 lines long, brownish with a darker elliptical mark on each side, Ala-
mos. September 16to30. No. 664.—Dr. Palmer says this tree has a symmetrical
top. It wasonly seen in fruit. With this species I am inclined to refer Palmer’s No.
88 (1886) from Baranca of the State of Jalisco referred to ‘‘Lysiloma (?) sp.” by Mr,
Watson in Proc, Amer, Acad. xx. 410. Palmer’s No. 88 is simply in flower and
the leaflets, immature, are smaller and described as glabrous. Even in fruiting
specimens there is considerable difference in the size of the leaflets. The pubes-
cence is developed by age. No. 88, which appears to be glabrous even under
an ordinary lens, shows under the high power the nascent pubescence. ‘The
stipules are wanting in my specimens, and the tips of the leaflets are a little dif-
ferent from Mr. Watson’s specimen but in other respects it seems to be the same.
This well-marked new species belongs to Mr. Bentham’s second section of this
genus. It may well bear the name of Mr. Watson, who has characterized but
not named the species.

Lysiloma Acapulcensis Benth., var. brevispicata, n. var. A large tree, 30 to 40
feet high, 1 foot or more iu diameter: spikes very short, 6 to 10 lines long.—Our
specimens are without fruit but seem to differ from this species only in the very
short spikes of flowers. Near Alamos. March 26 to April 8. No. 317. Palmer’s
plant from Jalisco (1885) is a shrub only 12 feet high. Pringle (1889) has col-
lected the species in fruit from the same region, The trees are fast disappearing.
Dr. Palmer says it resembles the Mesquit and is a good durable wood and makes
a fine shade tree. Called ‘‘ Tepebuaje.”

Pithecolobium Mexicanum, n. sp. Small tree, 15 to 20 feet high, 1 foot in diame-
ter: leaves with straight stipular spines (sometimes wanting) 1 line long; pinnw
2to5 pairs; leaflets 5 to 10 pairs, oblong, 2 to 4 lines long, midribs a little ec-
centric, puberulent, as is also the rhachis and branches: inflorescence paniculate ;
flowers in heads, pedicellate ; pedicels 1 to2 lines long: calyx $line long: corolla
14 lines long; the petals spreading or reflexed: stamens long, numerous: legumes
oblong, somewhat constricted, 3 to 4 inches long, 1 inch broad, straight, its valves
not elastic nor revolute: seeds 2, oval, 2 to 4 lines long.—In the Alamos Mountain.
March 26 to April 8. No, 297. Seeming nearest P. albicans Benth., but peculiar
in its pedicelled flowers. Commonly called ‘‘Chino.” The tree has much the
habit of the Mesquit and is valuable for its wood ; it is now rarely seen and is fast
becoming exterminated.

Sedum Alamosanum Watson. Proc. Amer. Acad. xxv. 148. This is the type, the
descriptions being drawn from the vegetative plant. The floral characters are
here appended: Racemes 2 to 8-flowered: flowers pinkish; sepals 1 line long:
petals 14 to 2 lines long: stamens 10, Collected on the side of a ravine, half way
up themountain, Alamos. March 26 to April 8. No. 273.

Gronovia scandens L. This plant climbs over bushes and to the tops of the highest
trees. Alamos. September 16 to 30. No. 630.

Cuphea calcarata Benth. (?) Alamos. September 16 to 30. No. 729.

Schizocarpum Palmeri Cogniaux and Rose, n.sp. Stem long and slender with short
close pubescence, intermixed with long scattered hairs, or becoming glabrate:

male flowers on peduncles 1 inch or more long, large, solitary, axillary, yellow ;
calyx short, tubular below, its lobes filiform; corolla funnel-form; stamens 3 with
distended filaments-and with anthers elongated, more or less curved; pistil
none: fertile flowers subsessile; calyx and corolla as in male-flower; ovary

ovules in the locelli, solitary ascending (!); fruit 14 inches long, turgid, ovoid,
indehiscent or bursting irregularly, glabrous; seeds 3 to 4 lines long, glabrous,
black, flattened, tapering to an obtuse apex.—Climbs over fences and bushes
along water-courses and in cafions near Alamos. September 16 to 30. No, 725,

Echinopepon' cirrhopedunculatus, n.sp. Stems slender, climbing over bushes,
glabrous except a bunch of white hairs at the nodes: leaves variable from orbic-
ular with deep sinus and shallow lobes, to ovate with deep lobes and almost
truncate base; the lobes and apex spiny tipped ; the upper surface white papillose
with short spiny hairs on the veins, below somewhat scabrous; petiole about the
length of the leaves, spinescent with a cluster of white hairs at the base of the

There is still considerable difference of opinion ‘among botanists as to the claims
of this group to generic rank, As held by Cogniaux and other distinguished botan-
ists this should be referred to Echinocystis cirrhopedunculata. He says, however,
there is reason for either course—‘ vous verrez que j’ai été longtemps indécis avant de
réunir ces deux genres dans ma monographie: on peut donner de bonnes raisons
pour la réunion, et aussi pour la séparation.” Still others would refer this to
IMicrampelis cirrhopedunculata., claiming that Rafinesque’s genus should be substi-
tuted for Echinocystis. See Pitt. 11. 127, ete.

who has kindly looked over my plant, makes the following note: Votre Hchino-
pepon nouveau est bien curieux et differe beaucoup de tous les autres, surtout
par son trés-long péduncule filiforme. Je crois qu’il faudra le placer pres de mon
Echinocystis torquata (Monogr., p. 803), avec lequel il n’a cependant pas trop de

puberulent : racemes terminal, compound, 3 to 6 inches long: styles 5, tardily
separating: fruit 2 lines in diameter. Alamos Mountain. March 26 to April 8.
No. 351. A. pubescens has been considered by Benth. & Hook., Gray and Wat-
son, and most other writers as simply a form of 4. humilis and our plant may
properly belong to that species. In the absence of leaves, however, it is difficult
to decide just what species it is, and if distinct from A. humilis I am not
altogether sure that it is 4. pubescens,

Chiococca racemosa L. An upright-growing shrub, 6 feet high. The leaves are
somewhat smaller than any specimens in the National Herbarium. Grows on
hillside near Alamos. Sept. 16 to 30. No, 735,

peduncles filiform: involucre 1 to 2 lines long, its bract slender, acute, with
scarious margins and a brown gland along the back: rays about 50, slender, violet.
—Grows half way up the mountan side in shade of rocks. Alamos. March 26 to
April 8. No, 348. This is nearest E. divergens, but it has different pubescence,

courses in dense shade, Alamos, Sept. 16 to 30. No, 722.

Guardiola platyphylla Gray. <A bushy shrub about 3 feet high. Common on the
gravelly beds just above the river near Alamos. March 26 to April 8 No. 280.

Melampodium cupulatum Gray. Common along ravines, on hillsides, and in
cafions. Alamos. September 16 to 30.. No. 726. Also common at Agiabampo.

intense whiteness which disappears, somewhat, in drying. Alamos. March 26
to April 8. No. 391.

Tragoceros MocinianusGray. Proc. Amer. Acad. xx1. 388 Flowers creamy white.
Very common on sandy bottoms and in cajions, but has only been collected
before by Palmer in SW. Chihuahua in 1885. Pringle’s No. 2450 from Jalisco.
distributed as this species answers better to T. microglossus DC. Alamos. Sep-
tember 16 to 30. No. 646.

Zinnia linearis Benth., var. latifolia, n. var. Low and somewhat spreading:
leaves broader, lanceolate, 1 to 14 inches long, 2 to 4 lines broad, 3-nerved : rays.
few, always 7: akenes with 2 unequal awns.—Alamos. March 26 to April 8.
No, 352. Only asingle specimen found near the base of the mountain. Although
this plant does not seem to answer very well for Z. linearis, yet it is very sim-
ilar in the color of the flowers and in its akenes, but on account of the scanty ma-
terial it seems best to make it a form of this species.

103

Sclerocarpus spatulatus, n. sp. Several feet high with widely spreading branches:
leaves alternate, 3 to 5 inches long including the petioles, eoarsely serrate, a lit-
tle scabrous above, appressed-pubescent below: involucre bracts 3 to 6 lines
long, hirsute: rays yellow: central disk-flowers sterile.—Very common in woods
and along streams about Alamos, September 16 to 30. No. 649.

Montanoa, sp. Three feet high with several stems: leaves opposite, ovate-lanceo-
late 3 to 5 inches long by 2 inches broad, acuminate, 3-nerved, sub-entire, hispid
above, villous-pubescent beneath: involucre bracts very small (2 lines long) mu-
cronate : chaffy bracts large (6 lines long), glabrous, with mucronate tip reflexed :
rays not seen: disk-corolla 2 lines long; proper tube slender (1 line long), swol-
len at base, abruptly enlarged into the long slightly puberulent throat: style
with bulbous base, hardened in age, attached or deciduous from the akenes:
akenes glabrous, top-shaped, 14 lines long, without pappus.—Alamos. March
26 to April 8. No. 361, A single plant found half way up the mountain side.
It is called ‘‘Bolallaqui;” it exudes from the stem a gum which is much valued
by the common people for its healing properties. Although the number of rays
is not known, it clearly belongs to De Candolle’s § Acanthocaphae. By comparing
the flowers with those of M. grandiflora (Palmer’s No. 492 of 1886), I find that
the corolla is shorter and less pubescent and the latter lacks the bulbous style.
M., subtruncata Gray has still shorter corolla (14 lines long) with a very short
proper tube and a more abrupt throat, but possesses the bulbous base of our plant.
The akenes of M. subtruncata have a thick margin forming a low crown which
is not possessed by the other two. M. patens has a corolla and akene with crown
similar to M. subtruncata, but with or without a small bulbous style-base. There
seem to be very good specific characters in the structure of the disk-flowers.

Montanoa (Enocoma), sp. Large, loose shrub, 8 to 10 feet high: leaves 2 to 6 inches
long (including the 4 inch petiole), lanceolate, with acuminate tip and cuneate
base, scabrous above, hirsute below, coarsely serrate or sub-entire: flowers in
corymbose clusters: pedicels slender, hairy : involucre in one series of about 5
bracts: rays 2 to 4, very small, white : disk-flowers 3 to 5: chaff very hairy on
the back, narrowed into a mucronate tip. Alamos. March 26 to April 8. No.
394. This is a loose-growing shrub with many stems, and the habitof the elder,

Zexmenia podocephala Gray. About 3 feet high. Only a single plant seen near
the base of the mountain. Alamos. March 26 to April 8. No. 363.

Zexmenia fruticosa, n. sp. Upright shrub, 8 feet high: leaves lanceolate to ovate-
lanceolate, 2 to 4 inches long sharply serrate, scabrous: heads terminating the
branches, or in corymbs of 3 to 5: involucre bracts in 2 or 3 series, imbricate,
hispid: rays small, yellow: akenes slender, 2 lines long, with awns as long or
longer.—Common along streams and on mountain side about Alamos. September
16 to 30. No. 645,

Viguiera montana, n. sp. Two to three feet high, slender, scabrous: leaves oppo-
site (except some upper bract-like ones), linear-lanceolate, 4 to 5 inches long by 3
to 7 lines broad, acuminate, sessile, 3-nerved, scabrous above, prominently reticu-
lated below: head turbinate, 6 lines long, with bracts closely imbricated in 5 or
6 series: bracts oblong, obtuse, or abruptly mucronate, conspicuously ciliate,
with soft white hairs: rays small, oblong, 5 or 6: disk-flowers 2 lines long:
akenes 2 to 24 lines long, villous-pubescent: pappus conspicuous, with two un-
equal awns and with several intermediate palez, laciniate, a line long.—Near
the summit of the mountain, under shade of oaks; at the time of gathering,
almost past blooming. Alamos. March 25 to April 8. No. 340. A peculiar
Viguiera, differing from all other species we have examined, in its many series
of imbricating involucre bracts; in this respect it is most like V. Purisime. The
stems are slender and purplish and the base has a tuft of wool as in the native
species of Perezia. Alamos. March 30 to April 8. No. 340. It resembles V.
blepharolepis, but the heads are smaller, bracts more numerous and glabrous on
the back.

104

Tithonia Palmeri, u. sp. Four to six feet high, more or less hispid-pubescent:: lower
leaves very large, over 1 foot long, 10 inches broad with a somewhat cordate
base ; upper leaves oblong with truncate or cuneate base coarsely serrate ; petioles
more or less winged, scabrous and hispid-pubescent: heads on long peduncles
(little thickened above), small, 6 to 9 lines long: involucre bracts about 2 series,
short; the outer ones narrow and acute; the inner ones broad and obtuse:
akenes 3 lines long, with 1 or 2 awns and 3 intermediate palew: rays oblong, 6
lines long, ‘‘ yellow to orange.”—Along water-courses and in cafions, Alamos.
September 16 to 30. No, 721, It resembles 7. tagetifolia, but with different
pubescence, involucre, rays, and pappus.

Tithonia (?) fruticosa Canby and Rose,n.sp. Shrubby, 5 to 10 feet high; younger
part silky-pubescent: leaves alternate, lanceolate, acuminate, 6 to 8 inches long
(including the petioles) cuneate at base, slightly crenately-toothed, somewhat
reticulated and soft pubescent below; appressed and somewhat scabrous above:
heads on short axillary or terminal peduncles, 1 inch high: involucre campanulate
of 3 or 4 rows of broad, oblong, and obtuse bracts: ray-flowers pistillate and ster-
ile, 12 to 15, the slender ligules 1} inches long: akenes 3 lines long, pubescent :
pappus composed of united scales forming a short crown.—Only two plants seen.
Among bushes near a water-course. Alamos. March 26to April 8. No. 303. Dr.
Palmer says that at a distance this plant appears to be a beautiful shrub, with
numerous, large, bright-colored flowers. The stem is 4 inches in diameter at
the base and the wood resembles the Elder. This species is very different from
the rest of the genus in its tall shrubby habit.

ray-akenes abortive, 2-awned; disk-akenes very slender, 5 to 9 lines long,
4-angled, glabrous, becoming curved outward and with 4 to 5 retrorsely barbed
awns.—Very rare; in the shade along a water-course near Alamos. March 26
to April 8. No. 278. September 16 to 30. Letter Z. Dr. Palmer says it is a loose
grower with many branches and abundant flowers, which have the strong odor
of the marigold.

EXPLANATION OF PLATE VI.—Plant natural size; b, akene much enlarged.

Perityle microglossa Benth, var. effusa Gray. Bidens pilosa Gray, non L. Proc.
Amer. Acad. xxi, 432,

This plant differs from P, microglossa in several important particulars beside
those pointed out in the Syn, Flora. The habit and leaves are different, the rays
white instead of yellow, and the inflorescence differs some. Its relationship
seems to be with P. microcephala, from which it differs in its pubescence, somewhat
larger heads, different disk-corolla, etc. Palmer’s 238 is a coarser plant, more
villose and with fewer heads, but it apparently belongs here. Like the latter
is Palmer’s 373, from the mountain cafions about Alamos, where it is very common.

Porophyllum macrocephalum DC. Grows under bushes in cafions. It has the
very strong odor of Rhue. Alamos. Sept. 16 to 30. No. 716.

Tagetes LemmoniGray. Collected but once before and this by Lemmon in southern
Arizona. Palmer found but a single plant near water-course in the middle of the
mountains of Alamos. It grows about 3 feet high, with a large top. March 26
to April 8. No. 339,

Pectis punctata Jacq. Stems prostrate or ascending. Common on stony ridges.
Alamos. Sept. 16 to 30. No. 730,

Pectis prostrata Cav. Common near the water in grassy bottoms near Alamos.
Sept. 16 to 30. No. 659.

Hymenatherum anomalum Canby & Rose, n. sp. Slender annual, 6 to 20 inches
high, with many slender branches, glabrous or nearly so: leaves opposite or
alternate, with 7 to 9 filiform segments bearing large oblong oil glands: involucre
campanulate; bracts in 2 series, equal, free, about 2 lines long, acute, broadly
lanceolate, bearing 1 to 5 oblong oil glands: rays conspicuous, about 10, spread-
ing, oblong, 5 lines long, 3-toothed: disk-flower tubular, 14 lines long, with throat
longer than the proper tube and 5-toothed: style-branches elongated, obtuse:
akenes linear-turbinate, slightly pilose: pappus paleaceous, in 2 series: outer
series 10; paleze spatulate, laciniate-toothed ; inner series 10, 3-aristata, the inner
longer, hispid.—Abundant near the base of Alamos Mountain. March 26 to
April 8. No. 346.

This genus combines the characters of several closely related genera but is near-
est Hymenatherum, yet it seems to break down its most distinctive character, viz,
the connate involucre, It seems to belong clearly to the subtribe Tagetinex as
laid down by B. & H. and only differs in having a double involucre. It differs from
Hymenatherum in having 2 series of bracts and these free, and as defined by B. &
H. in having a conical receptacle and in its 3-toothed ray and merely toothed
disk-flowers and pappus in 2 series. But as stated by Dr. Gray in a later
revision most of these characters break down in certain species. Of the species
of this genus, it resembles most H. Neo-Mexicanum, resembling it in habit and
having a similar receptacle. It has the free involucral bracts of Adenophyllum
but with different style-tips, and the pappus is very different from 4. coccineum,
the only species left in this genus by Dr. Gray. It has the free bracts and the
bristles at the base of the leaves of Pectis, but with a different style and recep-
tacle.

EXPLANATION OF PLATE VII.—Plant natural size; a, ray; b, corolla; c, style; d, pappus; all
enlarged,

Perezia montana, n. sp. Three to five feet high, slender, purplish, glabrous:
leaves coriaceous, reticulated, narrowly oblong, 3 to 6 inches long, 9 to 12 lines
broad, with a broad clasping base, spinose-dentate: panicle loose, spreading,
glabrous: involucral scales 3 to 5 series, narrowly oblong, acute, sometimes a little
obtuse, the lower and smaller ones mucronate, glabrous except the puberulent
margin: akenes glabrous, 3 lines long, flattened, delicately ribbed, narrowed at
apex.— Very rarely seen: grows under oaks on the higher parts of the Alamos
Mountain. March 26 to April 8. No. 285. Belonging to the P. rigida group as
arranged by Dr. Gray.

EXPLANATION OF PLATE VIII.—Section from the top and bottom of plant, natuzal size and
the base of stem showing tufts of wood, much enlarged; ¢, akene.

106

Trixis obvallata H. & A. It grows about 2 feet high: the flowers are yellow, with
a strong pine odor. It is commonly called “ Yerba del aira,” and is used exten-
sively by the common people in preparing a medicine for colds. Alamos. March
26 to April 8. No. 290. The plant differs from the figure in Beechey’s Report in
having entire leaves, but it seems the same as Pringle’s No, 2431, referred here by
Mr. Watson. It iscertainly very near T. longifolia; Parry and Palmer’s No. 1121,
referred here by Mr. Hemsley, is the same as our plant.

Lobelia laxiflora H. B. K. Only a few plants found in a deep ravine in a portion of
the Mountain of Alamos. March 26 to April 8. No. 288.

Heterotoma tenella! Mart. & Gal. This little plant is very variable; our speci-
men being either simple, 1 to 2 inches high, 1 to few flowered ; or taller, 10 to 12
inches high, and often branching. It grows in moist spots half way up the moun-
tain side. Alamos. March 26 to April 8. No. 289. Here belong also Bourgeau’s
No. 1722, distributed as Lobelia Cliffortiana, and also so referred by Hemsley in
Biol. Cent.-Amer., ii. 266. The Smithsonian Institute distribute under the same
name a plant from Orizaba, collected by Botteri (No, 1191), which is also this
species: this plant is tall, with long filiform branches. All of these specimens
differ from the original description in being puberulent below.

Metastelma latifolia, n.sp. High climbing shrub, nearly glabrous: leaves oblong
to lanceolate, roundish at base, obtuse with abrupt appendiculation, an inch long,
shortly pedunculate, margin and midrib pubescent (especially above): ambel
short-peduncled, 3 to 7-flowered : pedicels 1} lines long: flowers very small, less
than 1 line long: calyx lobes short, acute: corolla white, the oblong, obtuse
lobes densely puberulent on their inner margins: column very short if any : lobes
of the crown about equal the stigma.—Climbing over the tops of bushes, it
forms a compact mass of sweet-scented flowers. Alamos. September 16 to 30.
No. 665. According to the recent Revision of Dr. Gray (Proc. Amer. Acad, xxi.)
it comes in the sub-section containing M. Pringlet; but the foliage is different.

Buddleia verticillata H.B.K. A large bushy plant, early glabrate, 5 to 8 feet high,
with woody stems and rough bark: lower leaves ovate, 10 inches long and ser-
rate; upper leaves lanceolate with cuneate base,entire: heads on peduncles
4 to 8 lines long: flowers yellowish with ‘‘honey-like odor.” Common on good
soil everywhere about Alamos. March 26 to April 8. No. 279,

Erythrea Madrensis Hemsl. Biol. Cent.-Amer. ii, 346. Collected on the top of
Alamos Mountain. March26to April8. No.405. Seemann’s plant is the only one
referred here, but it seems to me that Parry and Palmer’s No. 567 (collected in
1878) should also be referred here,

The variety (No. 2597) in Mr. Pringle’s collection is lower and more spreading,
and with more twisted anthers.

Cordia (Sebestenoides) Sonor, n. sp. A small tree 10 to 20 feet high, 6 inches
in diameter; younger parts puberulent: leaves elliptical, 2 to 4 inches long,
obtuse, entire, a little scabrous above: racemes short and dense: calyx cylindri-
cal, 5 to 6 lines long: corolla white, 15 lines in diameter: stamens 5 to 7,
exserted.—A common tree in low places and on hillsides. About Alamos, Sep-
tember 16 to 30. No. 376.

Called Palo-de-Asta, and is one of the most beautiful of flowering trees; the
whole tree is covered with large clusters of white flowers (becoming lavender by
age), a short distance away entirely hiding from view the large shining leaves.
The tree has a symmetrical top and is well worthy of cultivation.

1 Another species of this genus has been wrongly distributed, viz, Palmer’s No. 48 (1886), from
Jalisco, referred to Lobelia cubnuda Gray,Proc. Amer. Acad, xxii. 433, which is H. arabidoides B. & H.

Heliotropium phyllostachyum Torr. Only a few plants found growing on acreek
bottom. Alamos. September 16 to 30. No. 637.

Krynitzkia micromeres Gray. This plant is very common on sandy bottoms.
Alamos. September 16 to 30. No. 397.

Ipomeea murucoides Rem. & Schultz, var. glabrata Gray. This plant is without
leaves (except very young ones), and its appearance is peculiar; as it is now
apparently for the first time collected in fruit, we append a description. A tree
20 to 30 feet high, 1 foot or more in diameter, with smooth bark and numerous
branches: leaves (immature) about 1 inch long, ovate-lanceolate, strongly reticu-
late and pubescent below: racemes terminal, many flowered: calyx as well as
pedicels and young branches puberulent: sepals oval, obtuse, 5 lines long:
corolla about 2 inches long, white, yellowish below: filaments pubescent at
base: capsule 10 lines long, 2-celled, 4- valve, 4-seeded: seeds 5 lines in length,
oblong, with a long coma upon the sides. The tree is called ‘“‘ Palo santo,” and
is very abundant about Alamos. No. 316.

The wood is of no commercial value. The Mexicans use the ashes for soap-
making. Dr. Palmer says: ‘‘ But one flower of a raceme opens at a time, and the
large tree, devoid of foliage, and with only 3 or 4 large flowers, presents a pecu-
liar appearance”, The flowers of our plant are similar to Gray’s type (Palmer's
No. 703, of 1886), and Pringle’s No. 2443 (of 1889), from near the same locality,
but the sepals are shorter and obtuse and not glabrate. The sepals resemble
Hemsley’s figure of the species, which is probably Gray’s form. According to
dates on the title pages, it appears that H. B. K.’s specific name macrantha is older
by one year than Rem. and Schultz, and if the oldest specific name is used,
Don’s combination should be taken up. Convolvulus macranthus H. B. K. Gen.
et Spec., ili. 95; Ipomea murucoides Rom. & Schultz, iv. 248; Ipomoea macrantha

Ipomeea bracteata Cav. This is aclimbing plant and without leaves, but with long
racemes of flowers with large purple bracts. Itis called “ Zicana.” It has large
tubers, like sweet potatoes, which are eaten raw by the Mexicans. Alamos.
March 30 to April 8. No. 313,

Ipomceea Grayi, n. sp. High climbing, glabrous or nearly so: leaves orbicular
to broadly ovate, 14 to 3 inches long, truncate or somewhat cordate at base, on
peduncles 2 to 5 inches long : peduncles variable, 14 to 3 lines long, 1 to several-
flowered: pedicels 14 to 24 inches long, somewhat thickened in fruit: sepals 3
to 4 lines long, broad and obtuse: corolla purple, 3 inches broad: stamens short,
included; capsule glabrous, ovate, 7 to 8 lines long, 4-valved, 2-celled, 4-seeded :
seeds 34 lines long, densely puberulent.—Alamos. September 16 to 30. No, 710.
Also collected by Dr, Palmer in SW. Chihuahua (1885). No. 102. This is a
profuse bloomer and a vigorous plant, climbing over fences, walls, and the high-
est trees.

I, rubro-cerulea' Gray, non Hooker. Proc. Amer. Acad. xx1. 434.

I. violacea Gray in herb. non L. To this latter species should be referred, accord-
ing to herbarium note of Dr. Gray, I. rubro-cerulea of Hemsley. Biol. Cent.-
Amer. 11. 393, I. Grayi differs from I. rubro-cerulea in its calyx teeth not being
‘‘subulate-linear,” the color of the corolla, and somewhat in the shape of the leaves.
Its alliances seem to be with I. pedicellaris Benth. of Central America, and with-
out seeing the type it is hard to separate the two.

‘After the above was prepared and sent to the printer, a letter was received from
Sir Joseph Hooker from which the following note, respecting this plant, is taken:
‘*Mr, Hemsley has told me that your Ipomea is quite distinct from I. rubro-cerulea
in the calyx, and also from I. pedicellaris which has an open sinus to the leaf.”

Ipomeea alata,' n. sp. Slender, climbing, glabrous throughout: leaves thin, trian-
gular in outline, 2t03 inches long, with broad open sinus, acuminate: pedun-
cles 2 to 4 incLes long, somewhat winged, 1 to 3-flowered: pedicels 9 lines long,
clavate thickened in fruit and deciduous with it: calyx “‘brick-red,” 9 lines
long, closely enveloping the ripe capsule; corolla “ scarlet,” salver-form: tube 2
inches long; limb 1 inch broad: stamens included or the anthers (2 to 4 lines
long) barely protruding: style included: stigma 2-lobed : capsule globular, 6 lines
in diameter, 2-celled, 4-seeded: seeds oblong, 3 to 4 lines in length, glabrous,
black.—Collected along creek bottoms and in cafions. It climbs over fences and
bushes at Alamos. September 16 to 30. No. 706. A peculiar species and seem-
ingly nearest I. rhodocalyx. I. alatipes has a similar winged peduncle, but the
flowers are 3 inches in diameter.

Solanum diversifolium Schl. About 6 feet high with loose branches: flowers
white. Collected in a shady ravine near the summit of the mountain. Alamos.
March 26 to April 8. No. 364.

Solanum Fendleri Van Huck. and Miill. About 3 feet high. Only a single plant
found and this in poor condition. At the base of Alamos Mountain, March 25 to
Aprils. No. 364. This approaches nearest Fendler’s No, 254, from Panama, of
any specimen seen in Gray or National Herbarium, but the pubescence is redder,
stems somewhat thorny, and racemes shorter.

Both these plants are merely tentatively referred as above as better material
may place them quite differently.

Solanum (Androcera) Grayi, n.sp. A slender annual, 1 to 2 feet high, stems more or
less thorny: leaves pinnately parted with ovate to oblong segments irregularly
toothed or cleft: racemes few-flowered: pedicels of the flower very short : of the
fruit 6 lines long, somewhat thickened: corolla small, 4 to 6 lines in diameter,
white: stamens irregular, 4 short, 1 long and curved : fruit very prickly.—Only a
few plants found in shade near Alamos. September 16 to 30. No. 633. Here
should be referred S. sisymbriifolium Gray, Proc. Amer. Acad, XXxI, 434, Al-
though a larger plant than Palmer’s present plant, the flowers are much
smaller thau in S. sisymbriifolium.

Solanum Amazonium Ker. A loose growing shrub 2 to 3 feet high with showy
purple flowers. Here should be referred No, 237 (1885) of Palmer from SW.
Chihuahua. It is S. elwagnifolium Gray, not Cav. Proc. Amer, Acad, XXxI. 434.
It differs conspicuously from 8. eleagnifolium in its slender, curved and dissimi-
lar stamens, and in its erect, fruiting pedicels: In the sterile flowers the calyx
is naked and three of the anthers much longer (6 lines long); in the fertile and
lower flowers the calyx is armed with prickles and the anthers nearly equal, or
often longer. Near Alamos. March 26 to April 8, No, 314.

Solanum verbascifolinm L. This is a shrub 4 to 5 feet high; its fruit is ‘ orange-
colored.” Common along river banks among bushes. Alamos. March 26 to
April 8. No. 392.

1 From the above letter of Sir Joseph Hooker is also taken the following note:
“Your I. alata may also, Mr. Hemsley thinks, be new and belongs to the same group
a, I. alatipes.

valley. The flowers are purple. Alamos, March 26 to April8. No, 318.

Tabebuia Palmeri, n. sp. A large tree 18 to 25 feet high: leaves opposite; leaflets
4, 2 to 5 inches long, oblong, obtuse at base, somewhat acuminate glabrous
or nearly so: flowers in close clusters at the ends of the naked branches: calyx
small, 2 to 3 lines long, covered with a mealy pubescence: corolla 14 to 2 inches
long with ample tube, mealy-pubernlent, white and purplish with yellow spots:
capsules terete, 15 inches long, 8 to 10 lines in diameter, straight or nearly so,
smooth and ribless: seeds very numerous in several series, oblong, 12 to 18 lines
long by 6 lines broad, winged at the ends.—In ravines near the base of the moun-
tain. Alamos. March 26 to April 8. No. 320; Called ‘‘Amapa.” <A beautiful
flowering tree with its large Paulownia-like flowers, which Dr. Palmer describes as
light-mauve at base, with white and yellow patches; they quickly fade. Only
a few flowers were found at the ends of the naked branches. Two leaves, each
with 4 leaflets, were found on the tree and Dr. Palmer says the new ones had not
begun to appear; there was an abundance of long black pods. The trunk of the
tree is covered with a thick, rough bark, resembling the oak; the wood is hard
and durable and is generally used for rafters in the construction of houses in this
region. That this is a Tabebuia, as considered by Benth. and Hook., there can
be very little doubt, although the inflorescence is a little more compact than the
known species of this genus, It is a little surprising that such a handsome tree
of some economie value has until now remained unknown.

403; also in September. Letter A. The natives speak of it as “Palo de la
flecha que de los semas brinca doras”—‘‘the arrow-wood which produces the
jumping beans. ” The generic position of the plant in which Carpocapsa is
found has long puzzled the botanist and entomologist. This is partly due to
the fact that the fruit which is stung (and this is the kind that is generally col-
lected) appears very different from those developed naturally. While this is
evidently a new species, still some uncertainty exists as to its position. Its
relationship is doubtless with Sebastiania, but it has close affinities with both
Gymnanthus and Bonania ; in habit it seems closer to the latter than to either the
other two, however its minute or obsolete calyx seems to be sufficient to keep
it vutof that genus. It has the rudimentary calyx and connate stamens of
Gymnanthus, but has dehiscent and contorted carpels which are thin walled ;
carpophore wanting; leaves serrate: all of which is at variance with this
genus, but corresponds with Bonania. Dr. Palmer says the boys gather these
beans, for which they find a ready market at Alamos. None of the beans which
had been stung were obtained, as they had all been carefully gathered before
Dr. Palmer’s visit and none of the so-called “ jumpers ” could be obtained at
Alamos at this time. The plant produces an abundance of milk, which is
said to be used by the Indians for poisoning their arrows. The milk readily
crystallizes into a clear, rather brittle substance, and is a violent cathartic.
The wood is very hard.

Ficus, sp. Alarge tree with many wide-spreading branches, 2 feet in diameter, with
thick, corky bark: leaves alternate, oblong-lanceolate, acute at both ends, 4 to
6 inches long, on a petiole 9 to 16 lines long: fruit nearly globose, 10 lines in
diameter on a very short pedicel (2 lineslong). Near Alamos. March 26 to April
8. No.367. The fruit is very abundant and edible and is called ‘‘Chalala.”
Dr. Palmer collected the same species at Hacienda San Miguel in southwest
Chihuahua in 1885,

Tradescantia Palmeri, n.sp. Stems erect, 6 to9 inches high, glabrous, or witha
pubescent line: leaves lanceolate, 1 to 24 inches long, glabrous except the ciliate
margin (and sheath), sessile, acute: umbels pedunculate (1 to 2inches long), 4 to
9-flowered: pedicels 3 to 5 lines long: sepals oval, 1} lines long: petals white,
1} lines long: stamens 6; filaments naked, the 3 longer with dilated filaments;
the 3 shorter almost sessile: style short: cells 3, each with 2 ovules: seeds 3,
triangular, 3-lobed, the margins revolute.—Found in moist shady places among
rocks near Alamos. September 16 to 30. No. 737.

It differs from most species of Tradescantia in its one-seeded cells; the ovules
however are two, the lower being abortive. The filaments differ considerably in
length, but the anthers are but slightly different. It is perhaps nearest the 7.
amplexicaulis and yet Iam not certain this is the proper section. It resembles
T. Disgrega very much in habit.

Mr. Watson hasjsuggested a relationship with 7. geniculata from which species
it differs in having the lower surface of the leaves glabrous (at least not villous) :
unequal stamens, with glabrous filaments : seeds of different shape, glabrous and
alveolate.

Leptorhroeo tenuifolia, n. sp. Slender annual, erect or a little spreading and root-
ing at the joints, glabrous or pubescent inlines: leaves linear, 1 to 14 inches
long, 1 to 2 lines broad, glabrous except a little pubescence at base: peduncles
from the axils of the leaves, mostly in clusters of 3 or 4, 9 to 12 lines long: flow-
ers in umbellets of 2 to 4, sometimes solitary, glabrous: sepals 1 line long:
petals, 1 line long, blue: stamens 6, of two lengths: capsule 3-celled, 3-seeded.
—It grows in shade along water-courses at Alamos. Sept. 16 to 30. No, 744.

This makes the second species for this genus and confirms the wisdom of sep-
arating it from Tradescantia, to which it is closely related and with which the
type species had for nearly forty years been associated. It differs from Zrades-
cantia chiefly in having but 1 ovule in each cell, and in the shape of the seeds
and the central position of thehilum. Itseems to be closely related to LZ. filiformis
of Southern Mexico, but appears quite distinct, differing especially in its more
erect habit, narrower and longer leaves, glabrous pedicels and calyx, and in the
inflorescence.

with a somewhat elevated umbo which is especially strong toward the base:
seeds 6 to 7 lines long. Collected near the summit of Alamos Mountain. March
26 to April 8. No. 374.

The seeds of this species are described as being an inch long, and the trees are said
to be 40 feet high. As is generally known, Dr. Engelmann found in his study of
the leaves of pines that the resin ducts might occupy one of three positions in
the parenchyina, viz, internal, parenchymatous, or peripheral. In this species
the ducts are peculiar and can not be assigned to any of the group. On each
side of the leaf are two ducts which with the surrounding strengthening cells
completely separate the parenchyma tissue into distinct regions; the ducts ex-
tend from the fibro-vascular bundle to the epidermis or its underlying strenghten-
ing cells. These ducts have the paradoxical position of being both peripheral
and internal. Dr, Engelmann in his arrangement places this species in the sec-
tion with internal ducts, but says he occasionally found parenchymatous ones.
We have not seen his specimens, but Palmer’s plant of 1836 referred here by Mr.
Watson has similar ducts. Dr. Palmer says there were many young plants which
would be especially fine for cultivation.

LIST OF PLANTS COLLECTED BY DR. E. PALMER IN ARIZONA
IN 1890.

By J. N. Rose.

Dr. Palmer, after having made large and valuable collections in Lower
California and Mexico in the early months of the year, visited Arizona
during the latter part of April, remaining there through May and June
and a part of July. He made collections at Camp Huachuea, Willow
Springs. and Fort Apache. A small collection made in 1889 at Camp
Huachuca which Dr. Palmer purchased is included in this report; these
plants are designated by letters only.

Camp Huachuea is about 15 miles from the Mexican border at the
base of the Huachuca Mountains, in the extreme southeastern part of
Arizona. Its elevation is 5,100 feet above sea level. The mountains
are rough and rocky. The soil is of decomposed granite. Dr, Palmer
was here from April 26 to May 21, and collected about one hundred
species. The season was unfavorable for his work as no rain had fallen
for seven months and the mountains and valleys were dry and barren,
and the only plants found in proper condition for collecting were in the
gardens and in two moist canons, The plants of this collection are
numbered from 416 to 478; unfortunately the numbers 450 to 459 were
repeated, hence the latter are designated by the letter a in addition.

The only other important collection! made at this place is that of Mr.
J. G. Lemmon and wife in 1882, a very large and valuable one, of which
over fifty species were new.

Willow Springs is in the White Mountains near the pass leading to
Fort Apache, at an altitude? of 7,600 feet. It is 75 miles south of Hol-
brook on the Atlantic and Pacifie Railroad and is reached only by stage.
The mountains here are covered with oaks and pines, and the two large
meadows from which this collection was largely made, kept damp by the
springs, were covered with vegetation. Dr. Palmer remained here from
June 10 to 25; the nights at this season are very cool, often thin ice is

1 Mr. Lemmon writes me that Dr. Palmer visited this place once before; as it was
during the dry season nothing of importance was obtained.
2Dr. Rothrock gives the altitude of the pass 7,400 feet and of Willow Springs 7,195.

formed. At this time he collected the plants numbered 479 to 574; on his
return from Fort Apache he remained two days, July 5 and 6, collecting
numbers 613 to 626.

Dr. Rothrock, in Wheeler’s Report, vol. vi., has forty eight species
from this place; most of these were recollected.

Fort Apache, upon the east fork of Salt River, in the Indian reserva-
tion of the valley of the White Mountains, has an altitude of 5,200 feet.’
It is only reached after one hundred miles of rough mountain staging.
The mountain here also is covered with oal s and pines, but the valley
is dry, having little or no vegetation. Salt ‘iver supplies water for the
fort and for irrigating the gardens and the arms of the Indians. The
temperature is 10° warmer than at WillowS tings. Dr, Palmer was at
Fort Apache from June 21 to 30, collecting p .nts numbered 575 to 613.

Dr. J. J. Rothrock made a small collection “ere in 1874. (Wheeler’s
Report, vi.) |

Vicia leucophza Greene. Bot. Gaz. vi. 217. About 2 feet high, hanging over
small plants. Leaflets 2 to 6, mostly 4. Flowers ‘‘lemon-colored with violet
spot.” Style densely hairy in the middle. Very near to this species is V. medio-
cincta Watson, and should be referred as var. mediocincta of the above species.
It differs only in its more narrow leaflets and stipules.

In the type (Palmer’s specimen) the stipules are described as linear, the flowers
solitary on pedicels (peduncles), 3 to 6 lines long. In the only other collection
of this form (Pringle’s, 1887) I find some of the stipules almost subhastate, and
some of the peduncles an inch or more long, with 2 flowers. I should state here
that I have not yet seen any specimens of this form with 6 leaflets.

A slight change is necessary in Mr. Greene’s description of the style, which he

120

says is ‘very villous at the apex,” while Lemmon’s plant, seemingly a part of
the type, has the styie hairy as above. The species has only been reported from
southwestern New Mexico and southeastern Arizona, while this variety is from
New Mexico. Palmer’s specimens were collected at Willow Springs July 5 and 6,

Hymenopappus Mexicanus Gray. Found on sandy river bottoms. Willow
Springs. June 10 to 20. No. 517.

Hymenopappus radiata, n. sp. Perennial from a long slender root, 14 feet high,
branching at base floccose-tomentose becoming somewhat glabrate above: leaves
mostly radical, 1 to 2 pinnate into narrow. linear segments: heads corymbose on
peduncles 1 to 2 inches long: involucre bracts broad, little or not at all pet-
aloid: rays about 5, white, 6 to 7 lines long: disk-flowers numerous; proper tube
short, about 4 line long; throat swollen, campanulate, about 1 line long; lobes
short, acute, about one-third the length of throat; anthers but not the fila-
ments exserted: akenes 1} to 2 lines long, obpyramidal, 4-angled with a delicate
intermediate nerve, glabrous or a little puberulent: pappus of numerous very
short palewe.—Common in low rich bottoms under pines and oaks. Willow
Springs. July 5 and 6. No. 615.

This species differs from all other species of Hymenopappus in the presence of
ray-flowers, but in other respects corresponds with this genus. Its habit is per-
haps more like H. filifolius, but the akenes and pappus are more like H. flavescens,
Although it seems undoubtedly a Hymenopappus, yet in all its external appear-
ances, including the rays, it resembles Leucampyx ; the disk-flowers, akenes, and
pappus are also similar. It has been a puzzle to me to separate this species
clearly from ZL. Newberryi, and it is questionable whether they ought not to go
together and be placed under Hymenopappus. The following are the slight dif-
ferences I note between the two: In H. radiata the pappus is not so deciduous,
the proper corolla tube is shorter, and the style-branches a little thicker and not
so papillose. The absence of the bracts on the receptacle seems to be the only
reliable character separating the two genera.

base of petals with white spot and a yellow ring below all:” stamens, 3 lines
long, distinct, sessile: capsule obtusish, about the length of calyx. Grows in
swamps. Willow Springs. June 10 to20. No. 342.

According to Dr. Gray’s Revision in Botanical Gazette this form would go into
his second section which contains only D. frigidum, asthe stamens are distinct and
almost sessile, but it can hardly be his variety dentatum as the leaves are of a
different shape, entire, and flowers purple. It resembles inhabit the Rocky Moun-
tain variety alpina which has been variously referred. But it is not the variety
alpina recently described by Mr. Greene, Pitt. ii, 12, as D. pauciflora as this has
a stamineal tube nearly as long as the anthers. Inthe recent arrangement of Mrs.
Brandegee, Zoe 1. 20, this would answer best in her variety Jeffreyi, but as it is
here defined, I do not think it includes all the forms placed under it by Dr. Gray,
It most resembles a specimen of Cusick’s collected in 1884 and distributed as D.
Media.

LIST OF PLANTS COLLECTED BY DR. EDWARD PALMER IN
1890 ON CARMEN ISLAND.’

By J. N. Rose.

This island is situated in the lower part of the Gulf of California, two-
thirds of the way down the Lower California coast, almost in sight of
land. It is 120 miles south of Guaymas. It is made up mostly of low
mountains, or hills, which in the north are only about 200 feet high, but
in the south rise from 800 to 1,000 feet, and are cut by many deep canons.
The surface is rocky, with very poor or no soil. No trees are found here;
a few shrubs, sometimes 15 feet high, give the prominent floral features
to the island. On the west side is a great salt bed covering about 640
acres to a depth of 12 feet, estimated to contain about 13,000,000 tons
of a very fine quality of salt. This island is ewned and controlled by a
gentleman at La Paz, and a large quantity of the salt is shipped both to
Guaymas and San Francisco, and, when the salt is ground, sells as the
very best quality for table use. The source? of this vast salt deposit is
said to come from the surrounding hills and mountains, Al the creeks
and caiions open into this lake and, from experiments made, their waters
are found to be charged with chloride of sodium. After the rains have
ceased, in about fifteen days, the water evaporates and the work of ex-
cavation can go on. The only botanist or collector, so far as I know,
who has visited this island is Dr. Edward Palmer. He has made two
visits and has very thoroughly collected the plants of the island. His
first visit was January 1 and 2,1870. I have not been able to learn the
number of species collected, yet it was not large. No report was pub-
lished on the plants, although most of them were then new species. One
or more of them have been identified from time to time as belonging to
new species and published as part of the type. Most of the others have
been collected elsewhere by Mr. Brandegee or by Dr. Palmer himself, and
published as new, without having seen the Carmen Island forms. Dr.
Palmer made a second visit last November and remained a week (No-

2In Bulletin No. 84 of the U.S. Hydrographic Office (p. 28) it is stated, however,
that although the lake is separated from the ocean by a strip of beach a quarter of a
mile wide, over which the sea never flows, yet the water rises and falls with the tide.

vember 1-7, 1890). He visited all parts of the island and brought back
asmall but interesting collection. The flora is almost identical with
that of the peninsula. Of this collection 49 species are known to be
common to the peninsula and island; others will doubtless be found; 2
species are alsocommon to Mexico, and 25 to the United States; of the
latter, 9 are grasses; 19 of the species were collected by Dr. Palmer at
La Paz in 1890; 7 species are, so far as known, local, 5 of which are
here for the first time described, The island was so thoroughly explored
that probably very few species will be added to the list, and a few details
will not be out of place. The number of genera represented on the
island is 60, and of species, 68, Of the species 21 are Polypetalie, 24
Gamopetale, 10 Apetalie, and 13 Monocotyledons. Of these, more
than one-half (37) belong to 4 families, viz: Leguminosae 7; Com-
posite 12; Kuphorbiacee 6; and Graminie 12; one family belongs to
each of the four groups mentioned above; and over one-third (24) be-
long to two families, viz: Composite and Gramine. Orchidacew and
Filices, the third and fourth largest families of Mexico, are not repre-
sented on the island.

Drymaria diffusa Rose, n, sp. Stems slender, much branched from a perennial base,
somewhat glandular-pubescent throughout: leaves thin, broadly ovate to deltoid,
2 to 4 inches long (on petioles somewhat longer), truncate at base, acute or
slightly acuminate at apex: inflorescence few-flowered cymes: pedicels filiform,
5 to8 lines long: sepals equal, 1 to 1j lines long, thin, oblong, acutish, delicately

This is D, glandulosa Watson, Proc. Amer. Acad. xvii, 328, in part. Our plant
differs from this species in its leaves not being so broad, and in having long petals:
lower stipules wanting or deciduous, not lacerate: sepals smaller and not so
strongly nerved.

Collected by Palmer in 1870 (No, 4) and distributed as D. ramossisima.

This species differs from D. virgatus in its shrubby habit, lower leaves, larger
and more numerous pods, etc. The marking on the side of the seed referred
to by Mr. Brandegee in his notes of this species seems to be a generic character,
and as it also varies in shape and size in different species it may be of some use in
identification. In D. virgatus, although the seed is not half as large as in the
above species, the marking is much larger.

below and extending beyond the tip of the sepal: petals 5, 1-nerved, about the
length of the sepals: crown in 3 series; outer of short filiform segments a little
longer than the tube of the calyx; inner one entire, cup-shaped: stamineal tube 8
to 9 lines long, glabrous; free part of filament ribbon-shaped, 5 lines long: ovary
very hairy: styles and stigmas 3, glabrous: fruit 14 inches in diameter, pilose.—

132

The plant is called “Sandia de la Passion.” ‘The flowers bloom early in the
morning and last but a part of the day; the ripe fruit, which has a sweetish taste,
is much relished by the children of the island.

This species seems nearest P. fetida, some forms of which have very similar
foliage, but differs in its larger flowers, smaller crown, longer stamineal tube, and
the peculiar tip of the sepal.

EXPLANATION OF PLATE XIV.—A branch with flowers and fruit shown; natural size.

flowers. A compact plant, the numerous branches interlacing form an impene-
trable mass. Found on the beach and in the cations. No, 875.

This plant has somewhat less dissected leaves than the type and approaches
near H fasciculata, from which it seems to differ only in being pubescent and in
having the leaves more dissected.

Brickellia brachiata Gray, var. GLABRATA Rose, n, var, Glabrous throughout, but
in other respects similar to the type, This is the glabrous form referred to on
page 83, from Santa Rosalia. The finding of this glabrous form a second time
indicates that it may be a common form along the Gulf, and being so much out
of the range of the type we have thought best to give it a varietal name.—On

subject of a short note in Bot. Cal. i. 397, by Dr. Gray. This was also obtained
by him last year at La Paz, and by Mr. Brandegee at the same place and time.

Porophyllum crassifolium Watson. Proc. Amer. Acad. xxiv. 57. A very common
plant along the beach, in the cafions, and on the mountain side, No. 879.

It was first collected on this island. It was distributed as “ P. tridentatum

LIST OF PLANTS COLLECTED BY THE U.S. S. ALBATROSS IN
1887-91 ALONG THE WESTERN COAST OF AMERICA.

The Division of Botany has from time to time reported upon collee-
tions made by the Albatross in its various cruises along the American
coast and among the islands of the Pacific. The collections here enu-
merated were made at various times, extending as far back as 1857, The
first and second parts are reports by Mr. J. N. Rose on collections made
by Prof. Alexander Agassiz! on Cocos and the ralapagos islands; the
third part is a list of ferns from southern Patagonia, which have been
determined by Prof. Daniel C. Eaton, of Yale College; the fourth part
is a report on the mosses from Fuegia and Patagonia, also by Prof.
Eaton, giving notes, synonymy, and bibliography, besides the descrip-
tion of a new species; the fifth part is a list of Liverworts from south-
ern Patagonia, by Mr. A. W. Evans, with descriptions and illustrations
of two new species; the sixth part contains a short list of the lichens
from southern Patagonia by J. W. Eckfeldt, of Philadelphia.

All the material upon which these reports are based has been
mounted and preserved in the National Herbarium.

1. LIST OF PLANTS FROM COCOS ISLAND.
By J. N. Rose.

The few plants here enumerated were gotten by Mr. Alexander
Agassiz in 1891, who seems to have spent but a single day (february
28) on this island.

This island lies southwest of Panama about 500 miles, in latitude 5°
35’ and longitude 87°.

Ipomcea pes-capree Swect.

Epidendrum sp. These specimens have neither flower nor fruit.

Paspalum vaginatum Swartz.

Polypodium sp. Three different species were obtained,

Nephrodium pectinatum Presl. I have not seen specimens of this species, and it
is doubtfully referred here.

Meteorum patens? Dozy and Molkenboer. “This seems to be M. patens of Dozy
and Molkenboer, judging by their figure; but it is not the same as the Wilkes
expedition specimen nor C. Wright’s from Cuba, These have a shorter, rounded,
and flatter leaf. M. avreum, from Java, 1s a good deal like the Cocos Island
specimen.”—D. C, E.

parative Zodlogy of Harvard College, Vol. xxiii, No. 1.

2. LIST OF PLANTS FROM GALAPAGOS ISLANDS.
By J. N. Rose.

These islands are ten in number, situated on the equator, and are 300
to 600 miles from the mainland of South America.

Two large collections have been made from these islands; First, that
of Charles Darwin in 1835, who obtained about 200 species; and second,
that of N. J. Andersson in 1851.

David Douglass, with Dr. Scouler, also spent several days on these
islands in 1825. Of the 150 species obtained by Douglass only 50 were
saved, and these in very poor condition. Hugh Cummings made a sinall
collection in 1829, Mr, Macrae also made a large collection, and Mr,
Edmonstone, in 1845, collected largely here. Admiral Du Petit-
Thouars obtained a few species. In 1845 Sir Joseph Hooker pub-
lished the first enumeration of the plants of these islands. He reports
upon 265 species, of which 253 are phanerogams and ferns, and of this
number 123 are described as new. In 1861 N. J. Andersson published
the second enumeration, being a report upon his collection (made in
1852) and including all the previons collections. He enumerates 392
species, of which 372 are phanerogams and ferns, and of these 72 are
described as new.

MALVACES.

Gossypium purpurascens Poir. (?) Duncan Island, April 2, This is prob-
ably the same plant that both Hooker and Andersson referred to the above
species. It is certainly near G. Barbadense L., but the leaves are more strongly
black-dotted than in any of the species in the National Herbarium. The flow-
ers appear to be yellow.

ZYGOPHYLLACEA).

Tribulus maximus L. Duncan Island. April 2.

Lam not able to separate this from the many forms of this species. I suppose
it is the same as the variety adscendens of Andersson, who obtained it from
both Charles and Chatham islands.

Tribulus servicens Ands., var. HUMIFUSUS Ands. Leaflets 7 pairs: petals 5 lines
long: carpels 5, one abortive.—Charles Island. April 1.

Also obtained here by Andersson. Only two small specimens were obtained,
but these have both flower and fruit. The original description contains no ref-
erence to the flowers and their size is given above. The flowers are considerably
larger than 7, terrestris, to which it is nearly related.

GERANIACES.

Oxalis (Hedysarioidez) Agassizi Rose, n. sp. Annual, erect, simple or branched,
glabrate; the younger parts hairy, 6 to 12 inches high: leaves on petioles 1 to 14
inches long; leaflets 3, the odd one distinet, the lateral on short petiolules,
broadly obovate, 6 to 9 lines long, 5 to 8 lines broad; surface finely reticulated,
resembling a minute honeycomb: peduncle about the length or longer than the
leaves: flowers few, yellow: ovary oblong, obtuse, 3 lines long.—Dunean Island.
April 2.

Three other species have been found on these islands, viz: O. carnosa Molina, O.
Cornelli Ands. and O. Barreliari Jacq., with none of which it agrees. It belongs
to the same section as the last species, but differs in its annual habit, color of
flowers, etc,

T have followed Sir Joseph Hooker in referring this plant to C. lutea, as I have
not been able to clearly separate it specifically, The acceptance of Andersson’s
conclusions would now require a new combination of names, and until further
material can be examined it had better remain under the old name.

There are only 10 true mosses in this collection, while not less than
152 species are attributed to Fuegia. It is to be hoped that as Uaited
States Government vessels pass through the Straits of Magellan some
person may be willing to gratify American bryologists by making large
collections of these interesting plants.

Dicranum robustum Hook. f. et Wils. Fl. Antarct, 406 t. 152, f. 8. Port Churruca,
Straits of Magellan. A form with nearly straight leaves. Var, PUNGENS Hook.
f. Handbook of New Zealand Flora, p. 412, was collected at Island Harbor, Pata-
gonia. It has the leaves more faleate and with even slenderer capillary points.

Dicranum imponens Montagne. Ann, d. sc. nat. t. xvi. 241, D. involutifolium
Sulliv. in Hook. Journ. of Bot. 1850, p. 316. Borja Bay, Straits of Magellan.
Two forms were collected, one with stems 6 inches long, the other only 2 inches
high and of a darker color.

Racomitrium rupestre Hook. f. et Wils. Fl. N. Z. ii. 75. Dryptodon rupestris,
Hook. f. et Wils. Fl. Antarct. p. 402, t. 152, f. 1. Port Churruea, Straits of
Magellan; barren plants, The plants have a yellowish brown color instead of
the lurid brown of the original description, but seem to differ in no other respect.

Racomitrium lanuginosum Bridel. Mayne Harbor, Patagonia; not in fruit.

Ulota fulvella Mitten. Journ. Linn. Soc. iv. 75. Borja Bay, Straits of Magellan,
growing on Berberis ilicifolia, in fruit. This is one of four species (U. fulvella,
U. eremitensis, U. glabella, and U. Fuegiana) into whieh Mr. Mitten divided the
Orthotrichum luteolum of the Flora Antarctica. The pedicels are 3 to 5 times
the length of the capsules, while Mr. Mitten’s description makes them only
twice as long, but the leaves agree with his character of “margined with a
single row of oblong hyaline cells.” The inner peristome he was unable to
find. These specimens show it to be composed of eight slender cilia, about half
the length of the outer teeth, each of a single row of cells.

Bryum coelophyllum, Eaton n. sp. Plant half an inch high, densely cespitose and
matted with brown branching radicles; stems slender, mostly simple, not comose-
capitate; leaves consimilar, loosely imbricated when dry, erect-spreading
when moist, broadly roundish-ovate from a wide and scarcely decurrent base,
very concave, obscurely pointed, margins crect or slightly incurved, entire,
nerve rather stout, extending almost to the apex; cells of the leaf rhomboid-
hexagonal, hyaline, those along the margin longer and narrower except near
the base and the apex; flowers.and fruit unknown,

Port Churruca, Straits of Magellan, A densely tufted plant with something
the appearance of the specimens of &, nirale collected by the Wilkes exploring
expedition, but the leaves here are shorter, broader, firmer, more concave, and
comparatively pointless, They measure 1.65 to 1.75 mm. in length, and are
nearly as broad, though it is difficult to measure their width, as under a cover-
glass they are forced into several longitudinal folds. The average length of
the leaf-cells is 0.05 mm. The color is a dull green, becoming brownish as the
leaves grow older. Bb. platyphyllum, as figured by Schwiegrichen (t. 324) has
leaves much like those of this moss, but differs in having the ends of the stems
and branches comose-capitate.

Ccelidium cochlearifolium Jaeg. et Sauerb, Adumbr. ii. p.383. Hypnum cochleari-
foliumSchwaegr. Suppl. i. sect. ii, p. 221, t. 88. Port Otway, Patagonia; in fruit,
the plant growing on a slender twig, and with long straggling branches like a
Meteorium. The allied species, C. auriculatum, though originally discovered in
the Straits of Magellan, is not in this collection. It has more decidedly auricu-
late leaves and a much longer pedicel than the present species.

Ptychomnion aciculare Jacg. et Sauerb. Adumbr. ii. 616. Hypnum aciculare.
Labill. Schwaegr. Suppl. t. 92. Hypnum cygnisetum C. Miill. Bryologia
Fuegiana, in “Flora,” 1885, p.425. Port Otway, Patagonia; not in fruit. Miiller
has separated the American from the New Zealand plant on account of its greater
robustness and its swan-necked pedicel. But some of the New Zealand specimens
are even stouter than the Patagonian, and the curved pedicels are found also in
New Zealand.

Hypnum fluitans L. Patagonia. Sterile specimen rather denser than the com-
mon forms of this species; possibly Amblystegium Fuegianum Mitten.

Hypopterygium Thouini Mont.in Ann. d. sc. Nat. ser. 3, iv. 86. Hypnum Thouini,
Schwaegr. Suppl. t. 289. Port Otway, Patagonia; in fruit. C. Miiller, in Bryol.
Fuegiana, expresses a doubt as to this moss having been found by Commerson in
Fuegia. In the Flora Antarctica it is stated that Capt. King gathered it at
Port Famine. The present fine specimens amply confirm the southern range of
the species.

This curious species is very doubtfully referred to the genus Lophocolea, from
whose typical species it differs especially in the large, entire amphigastria and
in the extremely short fertile branch with its involueral leaves reduced to a
single pair. The sharply curved line of insertion of the leaves (which is similar
to that found in certain Plagiochile) also distinguishes it from most Lophocolee,
where the leaves arerarely deeply decurrent ventrally. It differs from Chiloscyphus
in the position of the fertile branches and in the winged perianths.

REVISION OF THE NORTH AMERICAN SPECIES OF
HOFFMANSESGIA.

By E. M. Fister.

In this paper species of the United States and Mexico are ineluded.
Foreign species are omitted except where they extend into this country.
The genus is taken as commonly defined, no attempt being made except
to present a synoptical view of the species. This revision is based
upon the material contained in the National Herbarium, in which nearly
all the species are fully represented, and which has been placed in my
hands through the kindness of Dr. George Vasey. I am also indebted
to Dr. Sereno Watson, Dr. John M, Coulter, Dr. William Trelease, Mr.
John Donnell-Smith, and Mr. I. C. Martindale, who have placed at my
disposal the collections which they own or lave in charge. I am espe-
cially indebted to Dr, Coulter for his many suggestions and his assist-
ance at difficult points. The compound microscope was used contin-
ually throughout these observations, and is indispensable in testing
many relationships.

Historical sketch.—This genus was established by Cavenilles, and
published in his Icones iv. 63 (1797), as containing two species, H. fal-
caria and H. trifoliata. Two years later (1799), in Leones v. 1. t. 402, he
published the genus Pomaria, including one species, P. glandulosa.
De Candolle defined the genus Melanosticta and published it in his
Memoires Leguminose xii (1835), including one species, M, Burchellit.
Torrey and Gray (FI. N. A. i. 592) united them all without hesitation.
Up to that time (1840) there were only 5 or 4 species described in North
America, At the present time 15 species and 9 varieties have come
under my observation, of which 2 species and 4 varieties seem to have
been undescribed.

Characters.—The glands furnish the first and most important group
of characters, and in several instances furnish specific distinctions.
They may be thrown into two different divisions: stipitate glands and
lack sessile (or subsessile) glands. The former belong to Hoffmanseg-
gia proper (having petals with long claws) and the old genus Pomarta
(having petals with short claws); while the latter are characteristic of
the old genus Melanosticta. Another group contains both kinds. The
Melanosticta group is further separated into three divisions by the
characters of the glands on the flowers, which is sutticient to clear up

143

144

the confusion concerning HT. Jamesit and H. melanosticta. The claws
of the petals and the style furnish some important characters. The
pod furnishes some of the most important specific distinctions, but can
not be of prime importance in grouping, for the fruit of a species and
its varieties may differ widely.

SYNOPSIS.

§ 1. Stipitate-glandular (except No. 4): ovate stipules and ovate attenuate bracts membra-
naceous; leaflets oblong, nerveless: filaments straight, with short and thick hairs.

* Claws of petals long, densely glandular, that of vexillum thick and usually broadly di-
lated: filaments and oblong ovary glandular: style clavate, slightly beaked: pod faleate
and with persistent sepals: herbaceous.

1. H. falearia Cav. Ic. iv. t. 392 (1797). Stems procumbent, 2 to 25 em. high, from a
creeping root (bearing now and then a tuber), puberulent, sparsely glandular,
scarious at base: leaves with 7 to 11 pinne; leatlets 6 to 10 pairs, puberulent or
glabrate; stipules broadly ovate, scarcely acute: peduncle usually short, bear-
ing a raceme of few flowers on suberect pedicels: sepals scarcely acute, 4 to 5
mm. long: petals with inner edge of claw densely glandular as well as back of
vexillum which has a thick dilated claw: outer stamens with copious clavate
glands: pod falcate, 3 to 4m. long, with round apex and acute base, on recurved
pedicel, more or less glandular, compressed between the 8 to 12 dark obovate
seeds.

Habitat: From Southern Arizona through Mexico (San Luis Potosi) to Chili and
Patagonia.

Specimens examined: Arizona (Lemmon, 1881, in part); San Luis Potosi (Sehaffner
832, 1876); Argentine Republic (at Cordova, 1829; Patagonia, Andrews 333); Chili
(Morong 1191; Phillip’s distribution 1324); also specimens cultivated at the botanical
gardens of Montpellier (1824) and Delile (1821).

This polymorphic species has a wide distribution, and has been heretofore divided
into several species and varieties, The specimens found in the United States and
Mexico have been called H. stricta with its var. demisea, and H, densiflora, while those
of South America and those cultivated in France have been called H. falcaria, Mr.
Bentham remarks that ‘‘the above species (//. stricta, demissa and densiflora) agree
with H. falearia in their most important characters,” but does not state how they
differ. The only difference yet noticed between the North and South American forms
is that the latter have ovaries with fewer lands and the corolla is often a deeper yel-
low; otherwise they agree. Some of the Morong specimens are very low, erect, very
glandular, with rather dense racemes; while others are 45 em. high, with long loose
racemes. It differs from var, stricta in being procumbent and having the mature
fruit rounded at apex, approaching that of H. drepanocarpa in most respects. The
Schaffher and Lemmon specimens agree with the description of H, falearia, but
they agree more with the plants themselves. The following seem to be well marked
varieties:

Var. srricta. Erect, 10 to 80 em. high: stipules obtuse, villous on margin: pe-
duncles long, bearing a loose raceme of suberect flowers; sepals obtuse: vexillum
with claw usually more dilated: pod long, obtuse or acute, usually on spreading
pedicels; seeds 6 to 9.

cenco: style pubescent: pod slightly curved, 25 by 5 mm., acute, suberect on spread-
ing pedicels, scarcely glandular, compressed between the 6 to 9 seeds,

Habitat: Coahuila, 40 miles south of Saltillo.

Specimens examined: Coahuila (Palmer 275, type).

Closely related to H. oxycarpa. Type in Herb, Gray, J. Donnell-Smith, Canby
and Martindale.

The two following species I have not seen, but translate Mr. Bentham’s descrip-
tion as given in Gray, Pl. Wright. i. 57. “The first (§ Gladiata), including H, gladi-
ata and H, platycarpa, Herb, coll. Trin. Dubl., with the habit and foliage of H,
stricta, without black dots on leaves, has the flowers nearly as in H. Drummondii,
and a straight or slightly curved pod, blunt at apex, with the upper or seminal
suture more or less convex, and usually broadest below the middle.”

5. H. gladiata. Stipules ovate, acute: pinne 3 to 6 pairs and an odd one;
leaflets oblong, nerveless and glandless: calyx acute, hirsute, glandular: petals ob-
long, with very short stipes; pod lanceolate, slightly incurved, minutely hirsute,
and scarcely glandular, (Zimapan, Mexico, Coulter.)

6. H. platycarpa. Stipules ovate, acute; pinnew 4 to 6 pairs and an odd one;
leaflets oblong, nerveless, glandless: calyx acute, hirsute, glandular: petals ovate,
scarcely stipitate: pod broadly oblong, pubescent scarcely glandular, (Mexico,
Coulter.)

++ Verillum broad, sessile, glandular: style cylindrical: pod lunate (much curved), acute,
attenuate below, glabrous: glandular-stipellate.

7. H. Drummondii Torr. and Gray, Fl, N. Am, i. 393 (1840). Plants 8 to 10 em.
high, glabrate, glandular, much branched, frutescent from a shrubby base: leaves
small (15 to 25 em. long); pinne 3 (seldom 5); leaflets 4 to 6 pairs, linear (4 mm,
long); stipules small: flowers with conical bases: vexillum red spotted, nearly
naked below: filaments with few very short and blunt hairs, the outer glandular:
pods 2 em. long.

147

Habitat: From Austin to El Paso, Texas.

Specimens examined: Texas ( Wright, 1849).

The upper stamens are searcely dilated and with very large stipitate glands,

8. H. Texensis. Suffrutescent, searcely glandular, 20 em, high, everywhere the
grayish bark covered with a fine pubescence: stems intricately branched into many
very slender branchlets: leaves many: very small (10 to 18 mm. long); pinme 3, de-
ciduous; leaflets minute, 3 to 5 pairs; stipules minute, glandular: peduncles 2 to 4
cm. long, slender, with 2 to 5 minute flowers: vexillum with a dense tuft each side
of base: stamens glandless, the pubescence rather short, thick, pointed, dense be-
low on upper stamens: style very slender: pod 15 em, long.

Habitat: Texas, on the Nueces.

Specimens examined: ‘Texas (Berlandier 612, type).

Type in Herb, Gray.

This species is most nearly related to H. Drummondii in respect to the shape of leaf-
lets, pod, petals, and style; otherwise its gray, pubescent, flexuous branches and
branchlets (scarcely larger below than above), its many petioles without pinnwe and
short branchlets, its very small leaves, leaflets and flowers, its vexillum much tufted
at base, and its stamens not glandular but much pubescent, with the upper prom-
inently setose-appendaged, makes this a very distinct species.

+++ Vexillum with broad and thick claw, glandless as well as filaments: style very long
and cylindrical: pod lunate, with thin, lanceolate, deciduous sepals: stems frutes-
cent, greenish, virgale: leaves small; stipules and bracts lanceolate, caducous,

9. H. microphylla Torr. Mex. Bound. 58 (1859). Plant 2 to 12em, high, velvety
puberulent: pinne 3, the odd one twice as long and with 7 to 11 pairs of leaflets, the
lateral with 5 or 6 pairs; leatlets 3 mm. long, pubescent: racemes many, much elon-
gated, loose, with many flowers (buds blunt): sepals pubescent, *he lower much
broader, concave: style pubescent, inclined above: podlunate, both ends acute,

in part).

Palmer’s pubescent specimens of 543, from Sonora, are smaller in every respect,
with fewer flowers, the leaflets often glandular on margin, and the stamens with
longer pubescence. It is closely related to the next.

10. H. glabra. Glabrous throughout (except margin of stipules and calyx), 45 em.
(or more) high, rigid branched (usually fromone side): lateral pinnie 1 cm. long,
with 5 pairs of leaflets, the terminal slightiy longer and with 6 pairs: Tacemes

These two forms are distinct from IH. microphylla by growing (somewhat) in
clumps and being more or less intricately branched (even from below), in the rigidity
of the stems, in being entirely glabrous, in the pointed flowering buds, and the
strongly attenuate pod,

§2. With both stipitate and black sessile glands: flowers suberect, with ovate bracts and
deciduous sepals; stamens somewhat declined: pod broadly ascinaciform: suffrutes-
cent,

SYSTEMATIC AND ALPHABETIC INDEX OF NEW SPECIES OF
NORTH AMERICAN PHANEROGAMS AND PTERIDOPHYTES,
PUBLISHED IN 1891.*

Compiled by JOSEPHINE A. CLARK.

The increasing interest which is to-day manifested in systematic bot-
any demands some method of indexing which will bring together in
convenient form the information necessary to a complete history of the
investigations and discoveries which have been made in this line of
research. In the Botanical Division of the U.S. Department of Agri-
culture a carefully nade card index is kept, in which all new species
and new combinations are recorded. It is thought best to publish
this index which has been found so useful in our work, omitting the
synonomy and making no attempt to pass judgment upon the value of
any species. In other words, it is simply a record of the work ac-
complished during the year in this line, and designed in printed form
to be a convenience to monographers and others in their investigations,
To make this list still more useful, in cases of new species, the State
or region of the country in which they are found is given. <A double
enumeration of the species is made, viz, systematic and alphabetic.
In the former arrangement Durand’s Tndex Generum Phanerogamorum.
has been followed for convenience, this being the arrangement adopted
in the National Herbarium. In the ease of the revival of an old generic
name in place of the one now in use the name will be found under the
genus, as given in Durand’s Index; also when an author has substituted
anew generic name for an old one it will be found under the latter.
Where a genus has been transferred by an author to a different family
from that commonly accepted it will be placed under both families, A
new genus has, inclosed in brackets, the number of the genus it.
naturally follows, with the letter @ added, the number under which it is
found in the National Herbarium.

The author of the species, place of publication, with volume and page,
and. as stated 1 above, in cases of new species the locality are given.

* Iti is our purpose to publish an . annual index, and also to complete an index now
in preparation, covering preceding years back to 1885. That future issues of the
index may be as complete as possible, it is desired that authors will send reprints or
reviews to the National Herbarium of such of their publications as may not be
readily accessible. The accompanying carefully prepared systematic and alpha-
betic lists have been made under the tmmediate direction of my assistant, Mr. J. N.
Rose.—GEORGE VasKy, Loltanist, si

152

As a general rule, a single reference is cited, but exception is made
in cases of list names accoinpanied by sets of plants, and in first publi-
cations which are obscure or doubtful; a few names, merely list names,
so far as we know, have been included.

Otto Kuntze’s Revisio Generum Plantarum, with its thousands of
specific changes, has, thus far, been but partially indexed, and is, there-
fore, passed over for the present, as this list has already been long de-
layed.

A bibliography of the works cited in this index is here added.

LIST OF PLANTS COLLECTED BY C. S. SHELDON AND M. A.
CARLETON IN INDIAN TERRITORY IN 1891.

by J. M. HoLzincer.

This paper is a report on two collections of plants, chiefly from Indian
Territory, the first made by Mr. C. 8. Sheldon, the other by Mr. M. A.
Carleton, whose paper on the native plants of Oklahoma Territory and
adjacent districts appears herewith.

Mr. Sheldon collected during June, July, and August in the southern
half of the territory. Mr. Carleton was in the field from the middle of
April to the last of September, covering the north half of Indian Terri-
tory and the adjacent parts of Kansas, New Mexico, and Texas.

Valuable help and suggestions were received in the determinations
from Dr. George Vasey, who also determined the grasses. The Carices
were referred for verification to Prof. L. H. Bailey.

I.-C. 8S. SHELDON’S COLLECTION.

Mr. Sheldon’s route lay through Colbert, Caddo, Atoka, the Sans
Bois Mountains, Stomewall, McAlester, Erin Springs, Fort Sill, Cash
Creek, Anadarko, the Washita River, Mount Scott, the Shawnee Hills,
and Hartshorn.

on Mount Scott and probably throughout Wichita Mountains. July. No, 228.

This plant has the scaly bulb of the species to which it is here referred. The
flowers are, however, rather larger, and no plants could be found with leaves.
The Indians familiar with it claimed that it never had leaves. But this is prob-
ably an error. In dry seasons plants in bloom and having no leaves are

found in Minnesota.

Mr. Sheldon sent in the two numbers under the same date and from the same
locality, with the note that No. 78 has leaves larger and lighter colored and the
fruit nearly twice the size of 79. Both fruits are not yet mature. And it 1s pos-
sible to account for the difference in size of leaves and fruit on the ground of
difference of subsoil on which the trees stand, ete. At any rate our present
state of knowledge of the two forms does not seem to warrant us in making
anything more of these two numbers than simply Celfis MJississippiensia.

ZINGIBERACEZ.

Thalia dealbata Roscoe. Sans Bois Mountains. July. No. 90,

This plant has only the intlorescence “dusted over with powder.” Further,
Mr. Sheldon reports this as 7-10 feet high, when, according to Chapman, p.
465, it is usually only 3-5 feet high. There are two other specimens of this
species in the National Herbarium, Dr. Bigelow’s Rio Grande plant, collected
in 1853 near the Choctaw Agency, and Elihu Hall’s Texan plant No. 629. Hall’s
plant, however, differs from Bigelow’s and Sheldon’s in that it has a ring or
beard of hairs on the rachis at the base of each flower, while the others are
glabrous at that point. Some close field work is necessary to reconcile and
explain these discrepancies.

II—M. A. CARLETON’S COLLECTION.

Mr. Carleton started in at Vinita. From there he went westward
through the Creek and Seminole nations, Oklahoma, the Cheyenne
country, the southern tiers of counties in Kansas (April to July). Then
he went through the Cimarron Valley, Neutral Strip, into the north-
western counties of Texas, returning through the Indian Territory into
Kansas (August, September).

the Indian Territory in 1868. This form, so far as the three collections show, grows
only 3 to 5 inches high, The younger plants are simple, erect, with 3 to 5 pairs
of leaves below the branching inflorescence, while the older plants branch at

1 This species and 7. teretifolium look very much alike. When in flower they can be separated by
the number of stamens, 7. calycinuwm having 30, 7. teretifolium 20. In fruit the sepasation is more
difficult. The only tangible distinction that I could make out is in the duration of the sepals, which
fall with the corolla in T. teretifolium, but are somewhat persistent after the corolla falls in 7. caly-
cinum. The sepals are also produced below the point of insertion in T. calyeinum and not pro-
duced in 7. teretifolium. Coherently stated, the matter stands thus:

1, Talinum calycinum has 30 or more stamens, has sepals persistent after the corolla falls, and has
them produced below the point of insertion.

2. Talinum tercifolium has 20 stamens; its sepals fall with the corolla and are not produced bélow
the point of insertion.

1 The line between the groups of Riddellia isnot well drawn on the size of the rays, as in Gray,
Syn. FLii. pt. 1. pp. 317, 318. This plant has the short rays of &. arachnoidea, but the glabrous
achenes and entire pales of the pappus of &. tagetina, with which species it is therefore placed.

On examination, the following numbers had to be transferred to Riddellia tagetina Nutt.: (1) No. 628
of Mexican Boundary Survey; (2) a plant from New Mexico, sent in 1887 by W. B. Pease; (3) New-
berry’s plant in McComb’s expedition from the ‘‘Hills on the Chama;” (4) Letterman's plants, sent
in 1882, from Big Springs, Tex.

Dr. Watson, to whom this matter had been referred for counsel, said, in a letter on the subject:
“Dr. Gray evidently made too little allowance for variation in the rays of the first group in the genus.
In fact, it is only in R. Cooperi that the ray reaches the dimensions given. In &. tagetina it is any-
where from 2 to 3 lines in length.”

1 The other specimens of this form of S. perfoliata in the National Herbarium are: No. 679, of Mex-
ican Boundary Survey; Dr, Palmer’s No. 168, from Indian Territory; and a plant collected by C.
Thomas in the Rocky Mountains, in 1869. The Mexican Boundary plant was first named Dysmicodon
ovatum Nutt., but was subsequently changed to Specularia bifora Gray, with a question mark, The
other two plants were both found with Specularia perfoliata.

The capsules of this form are about 4 longer than in the common form; the seeds, on the other hand,
are $ smaller, and more oval, the ratio of the two diameters being as3 to 2. Speeularia leptocarpa has
seeds of about this shape, but just double this length. The seeds of Speeularia biflora the Syn. Fl.
ii, 1, describes as lenticular, but on examining some ripe seeds of Reverchon’s Texan plant under this
name, I find it to be oval, and of about the samo size as in the plants under consideration. The char-
acteristic difference between Speeulatia perfoliata and biflora isin the leaves, which are broader and
more amplexicaule in §. perfoliata, narrower and more distant on the stem in S. biflora, but still am-
plexicaule; the length of the capsule varies some in both, so does the position of the valves, certainly
in perfoliata; the Syn. Fl. ii. 11, places these “at or below the middle,” but both the figure in HBK.
nov. gen. et sp. iii. t. 265, and the National Hebarinm specimens show valves in this species above the
middle, The plants under consideration have the valves of the capsules above the middle, but have
the leaves of 8. perfoliata. On the other hand, Mr. F. V. Coville collected a plant in Pennsylvania
which has the more slender aspect, in leaves and stem, of S. bifora. There is other material in the
National Herbarium tending to show that Speeularia perfoliata and biflora are only variations of one
good species, variable in width of leaf, length of capsule, and position of valvular openings on the
same.

Ipomoea Carletoni Holzinger n. sp. A much branched glabrous vine, trailing on

apex, about 2 inches long, exclusive of petiole (one-half to an inch long): flowers
2 to 24 inches long, generally solitary but occasionally two or three at the end
of the common peduncle (1 to 1} inches long); pedicels little shorter than
peduncles: sepals one-half inch long, much imbricated, of unequal length, apex
rounded or obtuse and generally mucronulate, glabrous outside, minutely scab-
rous inside, the outer ones more decidedly so: stamens about } length of cor-
olla; filaments densely hairy near their point of insertion on corolla: style
about } length of corolla; stigma rather discoid-peltate than capitate. Mature
fruit and root are desiderata to complete the characters.—Logan County, Okla.,
and Cimarron River, near Guthrie. August. No. 472.

This is near J. longifolia, but is more slender, and smaller in all its parts. It
is not unlikely that it may turn out to be a small variety of this species, but
until fruit and root are observed it is decided not to place it so.

1 After an examination of the material in the National Herbarium of the five species belonging to
the section Oplotheca of this genus, I am led to think that they should be reduced to two or three
species. The section Dilopha is not represented in the collection, making a comprehensive examina
tion of all the species of this genus impossible at this time. The crests of the ripened fruit appear
to furnish the most satisfactory guide to the determination of these plants. The forms which have
these crests spiny we may, for convenience, designate as the Gracilis group, including F. gracilis,
Floridana and Drummondii, with the last two reduced to varieties of gracilis. The forms which
have the crests in the form of entire or barely crenulate wings may be designated as the Alata, in-
cluding F. interrupta, tomentosa, and Dr. Watson's Mexican F, alata.

These specimens have pistillate flowers barely developed, and yet the leaves

and the simultaneous appearance of flowers and leaves this western form seems
distinct from the eastern.

EUPHORBIACESA

Euphorbia strictior Holzingern.sp. Anerect perennial herb, from a thick deep root:
diffusely branched from the base, 15 to 25 inches high, glabrous except the inflo-
rescence; branches simple to the inflorescence, straight and rigid, grooved:
leaves alternate, 1 to 24 inches long, 1 line or less wide, generally more than
twice the length of the internodes, becoming relatively shorter toward the in-
florescence, sessile by a tapering base, the margin entire and revolute; texture
thick and leathery; no venation apparent except the midrib on the under
side; branches of the bi- or trifureate inflorescence subtended by opposite or
whorled leaves toward the extremities reduced, and there surpassed by the in-
volucre-bearing pedicels; pedicels + inch long, erect; involucral cup as broad

The subjoined disposition of these forms is suggested.
Froclichia, § Oplotheca.

I. Graciles. Crests spiny.
a. Crests 2, the alternate ones reduced each to a basal tubercle.
1. Branching diffusely from the base: F. gracilis Moq.
2, Larger, more erect, less branching: P. gracilis Moq., var. Floridana.
aa. Crests 5, the alternate ones each of J to 3 sharp spines: F. gracilis Moq., var. Drummondii.
II. Alate. Crests in the form of entire or barely crenulate wings: F. interrupta, tomentosa, alata.
Iam not prepared to differentiate these last three species. With more material than is at present
available they may be found reducible to two, or one, good species. Certainly they look puzzlingly
alike, so far as the present material shows.

as high, minutely puberulent: glands 4 or 5, yellowish, the petaloid appendage
reduced to a narrow, minutely scalloped margin; the pedicels carrying the
yellow anthers on short filaments raised above the cup; ovary raised on an erect
pedicel 1 line long, puberulent when young, becoming glabrate with age; the
three short styles slightly bifid; fruit when mature spherical in outline, nearly
2 lines in diameter, grooved between the carpels, crowned by the short persist-
ent styles, tardily dehiscent; seed oval, 14 lines long, grayish-green, obscurely
pitted, pointed at small end, marked at large end with a circular depressed area.

EXPLANATION OF PLATE XVITI.—Lower and upper part of plant natural size. Figs. a,

b, ¢, d, involucres, laid open, respectively of /. polyphylla, discoidalis, strictior Wrightii,

seen from the inside. Fig. e end view, Fig. f side view of seed of £. strietior, 3.

This differs from the type of &. Wrightit in the National Herbarium in being
less diffusely branched, with the branches more erect and more rigid; leaves
shorter, those in the inflorescence markedly reduced, shorter than the subtended
pedicels; petaloid appendages imuch narrower than the glands; fruit and seeds
larger. /, Wrightii is described as having 4 glands; one of the first involucres
examined from the type specimen had 5,

These two western species of Euphorbia are singularly paralleled by two
closely related Florida species, /. discoidalis Chapman and £. polyphylla Engelm,
In £. discoidalis the leaves of the inflorescence surpass the ultimate pedicels; in
EL. polyphylla they are shorter than the pedicels and bract-like. There is no ap-
preciable difference in their seeds,

Dr. Chapman, ona recent visit to the National Herbarium (May, 1892), stated
that he considered his own £. discoiddlis and Engelmann’s £. polyphylla one and
the same species; that he had had correspondence with Dr. Englemann on this
point, but was not sure that he had convinced that gentleman. Subsequent
study and comparison of these plants by the writer tend to establish the claim
of EF. polyphylla to a distinct species. The only mention of it in the author’s
works is on page 535: ‘‘Huphorbia polyphylla Engelm. Patterson, Check List,
p. 115 (name only).” Search for the description has proved fruitless. The only
publication known is through Curtiss’ plant No, 2498,* accompanied by a printed
label, “Huphorbia polyphylla Eng., n. sp. Dry, sandy soil. Indian River, Flor-
ida,” found in the herbaria at Columbia College, New York City, at Cambridge,
Mass., and at the Department of Agriculture. I therefore give here a descrip-
tion of this species:

Euphorbia polyphylla Engelm. in herb. An erect perennial, 6 to 12 inches
high, with usually several branches or primary stems from the base, simple for
5 to 10 inches; leaves alternate, crowded, numerous (somewhat as in Asclepias
verticillata), linear, succulent; those of the inflorescence opposite and always
shorter than the subtended pedicels; inflorescence bi- or trifurcate, its branches
elongated at maturity, and spreading; color of glands of the involucre purplish ;
ovary, fruit, and seed not appreciably different from those of £. discoidalis,

Thus, while these two Florida plants are certainly closely related, £. poly-
phylla differs in the short bracts of the inflorescence and the numerous, succu-
lent leaves of the stem. The glands in both vary fuom 5” to 4.)

1 These species may be distinguished as in the subjoined arrangement:
a. Glands yellowish
1. Euphorbia Wrightii Torr. and Gray. Pac. R. R. Rep. ii. 1855, 174,
Leaves of inflorescence longer than subtended pedicels.

2. Euphorbia strictior Holzinger. Petaloid appendage quite narrow.
Leaves of inflorescence shorter than subtended pedicels.

b. Glands purplish.

83. Euphorbia discoidalis Chapm. FI, 8. States, 1865, 401.
Leaves of inflorescence longer than subtended pedicels. Stem leaves relatively broad.

of leaves Engelmann’s plant agrees exactly with F. heterophylla, The only
character indicated in the specific name barbellata is found in varying degree in
the Linnean species and is not constant in all the leaves of any one plant.
Plants with strong bunches of hairs at the base of the leaves may at most be
designated by EF. heterophylla L., var. barbellata.

Leaves of inflorescence always shorter than subtended pedicels. The erect, simple stems
crowded with short, linear, succulent leaves.

[Mr. Simpson sent in the following description of this plant as observed in the field: ‘‘ Perennial;
stems several from the same root, or branching from the ground; ascending, slender, very leafy,
smooth, 6 to 10 inches high; leaves linear, fleshy, semiterete, smooth, entire, alternate, obtuse,
sessile, 8 to 12 lines long, a line or less wide,” corroborating the impression that the leaves are
sueculent.]

OBSERVATIONS ON THE NATIVE PLANTS OF OKLAHOMA
TERRITORY AND ADJACENT DISTRICTS.

By M. A. CARLETON, assistant botanist, Kansas Agricultural Experiment Station.

Tn order to make out anything like a complete statement of the dis-
tribution and variations of the native plants of the above-named
country, it would, of course, be necessary to survey systematically the
entire territory included, visiting each district at all seasons of the
year and taking two or three years of time for the purpose. The fol-
lowing notes are taken from a sojourn of Jess than six months in the
regions mentioned during the summer of 1891, although several of the
districts were visited two or three times during the summer. However,
1 have tuken pains to investigate all distributions and variations of
plants that seemed to be in any way significant, and itis hoped the
following summary of results may prove interesting.

I shall first give some notes on the plants of the different districts of
this region, and then direct attention to certain groups.

The entire region over which I have worked is approximately included
between the Arkansas and Canadian rivers, west of Arkansas and east
of Colorado and New Mexico, but some of my notes will refer to the
northeast portion of the Indian Territory and of New Mexico and the
southeast portion of Colorado. For convenience I divide the whole
region into five parts: (1) Oklahoma proper and eastern Indian Terri-
tory (or the Indian Territory east of the 98th meridian); (2) western
Indian Territory (west of the 98th meridian), excluding No Man’s Land;
(3) southwest Kansas (that part of Kansas cut off by the Arkansas
River); (4) No Man’s Land or Neutral Strip; and (5) Texas Panhandle
north of the Canadian River.

OKLAHOMA PROPER AND EASTERN INDIAN TERRITORY.

The greater part of this district I have visited but once, and then
early in the spring, and therefore can not say much about its flora from
my own knowledge. But I believe [ have made sufficient observations
to justify me in expressing the opinion that it is a country in the main

220

221

more especially adapted to horticulture, and in some places, perhaps,
stock-raising. I base this opinion partly upon the unusual abundance
of native species of fruits and partly upon the kind of soil present.
But of course there are other things to be taken into account, and I
fully admit the possibility of my being wrong in the matter,

Tam especially inclined to believe that small fruits and plums and
perhaps pears will do well in this district, particularly in the southern
and eastern portions, while peaches are already quite successfully grown
by Indians and squaw inen in the Cherokee Nation. The soil seems
to have the clayey consistency desirable for some fruits—as the plum—
and yet with sufficient sand or gravel to allow necessary drainage.

Moreover, native fruits are found in great abundance, as a rule. In
the Cherokee and Creek nations haws are extremely common, their
blossoms giving a white appearance to the woods and filling the air
with fragrance. They include the species Crataegus arborescens Ell.
and C. tomentosa L., var. mollis Gray, and no doubt others that I did
not observe. In nearly all this district the following species are quite
common, especially the first named: Chickasaw plum (Prunus Chicasa
Mx.), the ordinary wild plum (Prunus Americana Marshall), the wild
cherry (Prunus seroting Ehvh.), and Prunus gracilis Eng. and Gr.; and
in the timbered portions of the southern part of this district dewber-
ries and strawberries are so very abundant as to form extensive wild
gardens, as I observed myself, both to my pleasure in the berries they
furnished and to my annoyance in the obstruction they offered to the
pedestrian. The common blackberry and raspberry (Rubus villosus
Ait.and &. oecidentalis L.) are also found every where, and a low, bushy
species of blackberry (Rubus trivialis Mx.) seems to be rather common
at Vinita.

The usual western grasses thrive well, and a native species of clover
(Trifolium Carolinianum Mx.) is common at Okmulkee, the capital of
the Creek Nation. Another larger-headed, clover (Trifolium reflecum
u.) was collected in the southern Seminole Nation, but did not seem to
be very frequent.

In theeastern portions there is excellent timber, including quite a num-
ber of the common oaks, several hickories, hard and soft maple, green
ash, the elms, box elder, syeamore, yellow birch, black walnut, cotton-
wood, ete. Post oak is especially common, and makes fairly good timber,
Farther westward, except along streams, forests are reduced to small
groves of gnarly “black jack,” remotely scattered here and there.
From my one trip through the eastern part of this district it was im-
possible to gain much thorough knowledge of its timber.

WESTERN INDIAN TERRITORY.

For the entire region included in Kansas and Indian Territory the
28th meridian may be taken as a very good arbitrary line separating
the Great Plains flora into an eastern and western Section, some-

222

what distinct from each other in the character of their predominant
species. The natural boundary, it is true, would follow a zigzag
course, crossing this line many times, but its average course would lie
just about on this meridian. Going westward, such species as the fol-
lowing first make their appearance at this line: Astragalus mollissimus
Torr. (“‘loco”), Gaillardia pulchella Foug., Malvastrum coceineum Gray,
Artemisia filifolia Torr. (“sagebrush”), A. Wrightii Gray, ete., while
others, though occasionally found east of this line, now become more
largely predominant, as Gaillardia lanceolata Mx., Yucca angustifolia
Pursh (“ Mexican soap-plant”), Solanum eleagnifolium Cav., Evolvulus
argenteus Pursh, the grama grasses and several of the Drop-seed grasses.

And so, almost immediately after passing the meridian near King-
fisher, the flora of this district begins to exhibit the distinctive char-
acter common to the western Great Plains.

During the season of 1S9L there was an excellent growth of grasses
nearly all over this district, consisting mainly of the blue-stems (An-
dropogon provincialis Lam., A. nutans Linn., and A. Hallii Hack., v.
Aaveolus Hack.), interspersed throughout with a rich carpet of Buffalo
grass. But the season was an exceptionally wet one.

A very brilliant eryngium (Hryngium diffusum Torr.) gives pleasing
variety in some places to the usual monotony of this district; while
there are densely grown patches of the following species, scattered here
and there: Rudbeckia hirta L., Monarda citriodora Cerv., Hosackia Pur-
shiana Benth., Solanum eleagnifolium Cay., and Phaseolus pauciflorus
Benth. The last three are often found growing together in prairie-
dog towns, sometimes with Callirrhée involucrata Gray, and occasion-
ally Martynia proboscidea Glox.

In the North Canadian Valley a curious velvet-flowered crucifer
(Streptanthus hyacinthoides Hook.) appears as a apecies rather rare in
this district, so far as I have observed, and on the south side of the
same river, where the country is much different from the north side,
Lespedeza reticulata Pers. is occasionally found mingling with the more
common J. eapitata Mx. Then the Gypsum Hills have their peculiar
flora, to which I shall refer again. Although the greater portion of
this district will probably continue to be adapted only to the practice
of stock-raising, still there is no good reason why the eastern part may
not become a fine wheat-growing country, especially since it lies mainly
south of the counties of Harper and Barber, in Kansas, which have
already made a good record as a wheat-producing region. Besides, the
amount of rainfall, in the same longitude, seems to increase toward tke
south.

SOUTHWEST KANSAS.
Until during the last three years the plants of this district have been

very little known to botanists, and now the results of recent collections
disclose to us a flora rich in interesting forms, both in the way of add-

223

ing to our list many species new to Kansas, and exhibiting very strik-
ingly the transition from the eastern to the western plains flora. Prof.
W. A. Kellerman and Mr. B. B. Smyth have preceded me in making
collections of the plants of this district, and reported quite a number
of the species that I shall mention in these notes.

Here we find species that would be wholly out of place in eastern
Kansas, but which become very familiar to the collector in the “ Pan-
handle” or Neutral Strip, and which are invariably characteristic of
sandy barren regions.

But, going westward, before we reach the more barren portions of the
district we first find in Kingman, Pratt, Barber, and Comanche coun-
ties an extension from the Territory of the outcropping “red beds.”
Here there is not such a continuity of the flora as in the sandy regions,
but there are certain unusual forms quite local and broken in their
range, such as the following species: O.rytropis monticola Gray, found
so far only at Kingman, Gaillardia simplex Scheele., Astragalus bisulcatus
Gray, Senecio Douglasii DC. and Aster oblongifolius Nutt., var. rigidulus
Gray. Gypsum hills, too, are numerous here, and are accompanied by
their peculiar flora. Juniperus Virginiana L. and Celtis occidentalis L.
occur among these hills, the former probably as an extension of its
range from the Territory, rather than from eastern or northern Kansas.

Aside from the plants of the “red beds” and sandy regions, there
are a few others that become familiar forms in western Kansas, distrib-
uted quite generally over the high prairies. Of these, besides various
cacti, buffalo-grasses, and the graina grasses ( Boutelowa racemosa Lag.,
B. oligostachya Torr, and B. hirsuta Lag., there are the following
species: Lepachys Tagetes Gray (both purple and yellow-rayed forms),
Gaillardia pulchella Foug., Engelmannia pinnatifida Torr, and Gray,
Erysimum asperum DC., Astragalus lotiflorus Wook., A. mollissimus
Torr., Ipomea leptophylla Torr., Ginothera Harticegi Benth, ete.

The prevailing sunflower for all this district, and in fact for the entire
Arkansas Valley of the Great Plains, is Helianthus petiolaris Nutt., al-
though H. annuus L. is quite common.

Throughout this district, as in western Indian Territory, the most
important forage grasses are the butfalo-grass, blue-stems, switch grass
(Panicum virgatum L.), and the grama grasses. Along the Cimarron
River Sporobolus asperifolius Thurb. and Muhlenbergia gracillima Torr.
are also rather common, occurring in dense patches. Oneof the worst
weeds among the grasses is Schedonnardus Teranus Steudel, which
grows so thickly from Gray County westward as to become quite an
annoyance in the fields, particularly in those not constantly cultivated,
and is very provoking to the teamsters, by gathering mud on the wheels
of the wagon after a rain.

In Seward County, the common “tumble weed” is Cycloloma platy-
phyllum Mog. I saw specimens of this species on exhibition at Arkalon
which measured as much as 3 feet across. It is common in sandy
wastes,

224

There are some interesting species in the extreme southwestern por-
tion of this district that, as far as yet known, seem barely to have crossed
the Kansas line in their distribution northward. A particularly interest-
ing locality, in which alone some of these species have so far been
found in Kansas, is the Point of Rocks, a series of rocky bluffs jutting
out on the north side of the Cimarron River, near the Territory line, in
Morton County, at which place the headquarters of a number of cattle
men have been established for some time. I shall mention some of
these species that | noted at this place and in afew other localities.

Krameria secundiflora DC, is common from Guthrie to Kingtisher,
Okla., and westward, but collected in Kansas only at Point of Rocks,
The following have also been found so far only at Point of Rocks:
Hriogonum lachnogynum Torr., Berlandiera lyrata Benth., and Petalo-
stemon violaceus Mx., var. tenuis Coulter. The last one, described) by
Coulter in his Manual of the Phanerograms and Pteridophytes of
western Texas, is common farther south and west in Neutral Strip
and Texas. A singularly dwarfed form of C2nothera serrulata Nutt. is
wlso found at Point of Rocks, which is common on gypsum hills in
Indian Territory and in Neutral Strip and Panhandle, but seen nowhere
else in Kansas. Convolvulus incanus Vahl also has so far been found
only in Morton County, and Pectis angustifolia Torr., and Franseria
discolor Nutt. only in Seward County, besides others.

NEUTRAL STRIP (BEAVER COUNTY, OKLA.).

This district exhibits more fully the prevailing species of the south-
western Great Plains. Following the Cimarron River westward, the
species already mentioned as barely crossing the Kansas line first
become more common, then other new species appear, and finally, the
valley. of the Cimarron assuming canon form, and reaching the mesas
terminating the spurs of the mountains, the flora presents an appear-
ance quite similar to that of eastern New Mexico and the cations of
Texas Panhandle.

About 50 miles up the river from Morton County, Kans., two or
three species of “‘tree cactus” are first found, also a new Mentzelia,
M. multiflora Gray, Paronychia sessiliflora Nutt., Desmanthus Jamesit
Torr. and Gray, several interesting ferns among the mesas, anew grass,
Lycurus phleoides HBK., ete. Besides, nearly all the species found in
Morton, Stevens, and Seward counties, Kans., now become very com-
mon.

On the divide between the Cimarron and North Canadian great
patches of Hymenopappus Jlavescens Gray occur, filling the air with
their pungent odor. In the same region Hragrostis oxylepis Torr. and
Muhlenbergia gracillima Torr. are quite common, as well as Gaillardia
pinnatifida Torr., and a variety of Chrysopsis villosa Nutt., while Hoff-
manseggia stricta Benth. grows in patches scattered about.

225

Of trees, the following were noted in the Cimarron Canon: hack-
berry, red cedar, cottonwood, and soapwood (Sapindus marginatus
Willd.); also a species of willow (unrecognized), and among the mesas
a small sensitive plant (Jlimosa borealis Gray).

A very troublesome weed in the Cimarron canons is Tribulus maxi-
mus L. Even within the recent beginning of settlement of the Neutral
Strip this plant has spread quite rapidly over the few cultivated fields.
I found it growing on the farm of J. J. Burnett, at Garrett. He told
me it was already quite an annoyance.

In some places in the cafons very fair crops can be raised by irriga-
tion from springs flowing out of the mesas.

TEXAS PANHANDLE.

Although this is a large district, still I can give only a few notes in
regard to its flora, as I have made but one trip through it, passing from
Clayton, N. Mex., along the Denyer, Texas and Fort Worth Railroad to
Tascosa; thence down the canons of the South Canadian River to Cana-
dian City, and thence northward along the Santa Ie Railroad into the
Indian Territory.

treat portions of this district are vast plains of sand, but which
during the season of 181 were clothed with a very good growth of
grasses, including the blue stems and a few species of the genera
Sporobolus, Bouteloua, Triodia, and Panicum. These plains, on reaching
the river, are broken up into rocky mesas, and here the flora is rather
different.

Nearly all the characteristic species of the western Great Plains,
already mentioned as occurring in the other districts, are also found
everywhere in this district. Hence I shall note only a few of the
species not already mentioned.

The following species are found on the sandy plains of the western
and northern portions: Hriogonum alatum Torr., a giant Eriogonum,
more than 4 feet tall, common in the sand and on rocky bluffs in
Dallam County; Gilia rigidula Benth., a small blue-tlowered Gilia, found
in Dallam and Moore counties; Pentstemon anubiguus Torr., white flow-
ered, small, in Hartley County; Helianthus ciliaris DC., collected on
high prairies in Moore County, and Cuscuta cuspidata Eng., parasitic on
Artemisia filifolia Torr. and Ambrosia psilosrtachya DC., also in Moore
County.

Along the Canadian Cation a number of interesting species were also
noted. At Tascosa were found Bigelovia Wrightii Gray, Baccharis
salicina Torr. & Gray, and the mesquit, Prosopis juliflora DC., the beans
of which are used by Mexicans and Indians for food. A grove of this
last species was also noted in the Cheyenne and Arrapahoe reser vation,
about 12 miles northeast of Cantonment. It is also called screvw-
bean, and is quite common over the Southwest. A cactus (Opuntia
leptocaulis DO.), with very fine-looking fruit, was also collected at

226

Tascosa. The fruit is brilliant red, and at a distance looks like flowers.
It furnishes an acid juice that is quite refreshing to the tired traveler.
Bouteloua eriopoda Torr. grows in abundance near Tascosa, At Cana-
dian City a splendid malvaceous plant (Hibiscus lasiocarpus Cay.) 1s
common in the Canadian Valley (which here loses its canon form); also
Asclepias incarnata L. var. longifolia Gray was collected in the same
locality.

One of the foxtails (Setaria glauca Beauy.) forms a good part of the
hay in the Canadian Valley, and is considered to be of good quality.

The button bush (Cephalanthus occidentalis I.) is a very common
shrub in this valley and along streams in western Indian Territory.

This district is, on the whole, one vast cattle range, with a few cul-
tivated fields in the Canadian cations, watered by springs in the esas.

PLANTS CHARACTERISTIC OF SANDY REGIONS.

Having given some attention to the distribution of plants for several
years, I have become especially interested in the fact commonly known
that certain plants are usually associated with particular soils and cli-
mates. However, I can not hope to give anything new in this line,
except in so far as I may be able to present some additional observa-
tions, that may be of interest, from a study of the flora of the above
districts.

It has been noted by nearly all observers, I suppose, who have had
opportunity, that the plants of sandy or desert regions are usually,
and uniformly, protected against rapid transpiration by thickened
leaves and epidermis, absence or narrowness of leaves, or an unusual
amount of wooliness or hairiness. Now, as one would expect, we find
such characters commonly belonging to the species prevailing in the
western Great Plains. Of course the Great Basin and other regions
farther west and south than these districts that have come more imme-
diately under my own observations would probably furnish still better
examples of this peculiarity in plant distribution; but various circum-
stances do not permit me to include any notes upon those regions,
although I have been over a portion of the Great Basin.

It is particularly interesting to trace the gradually increasing tend-
ency to assume these protective characters on the part of those species
inhabiting both the eastern and western portions of the Great Plains
in their distribution westward. The very common evening Primrose
(Ginothera serrulata Nutt.) furnishes a good illustration. 1 have seen
specimens of this species in eastern Indian Territory growing more than
2 feet tall, with flowers nearly 2 inches across, while in Panhan-
dle, Texas, Neutral Strip, and at Point of Rocks, Kans., it becomes
peculiarly dwarfed, often not more than 6 inches tall, with flowers
little more than half an inch across, and the leaves and branches be-
come more whitish, narrower, and yet thicker, and the entire plant
more massive in proportion to its height. Between these extremes in-

227

termediate forms can be traced. Chrysopsis villosa Nutt. and Aplo-
pappus spinulosus DC. are well known to be quite variable, but their
variations, to the eastward and westward especially, will nearly always
be found to be in the line of a greater or less presence of protective
characters. Of the former, the very names of many of the described
varieties ought to, and do, indicate these facts, such as canescens, hispida,
foliosa, stenophylla, viseida, ete., while there are innumerable interme-
diate forms not worthy of varietal rank. Aiddellia tagetina Nutt. be-
comes much more woolly farther westward, and Lngelmannia pinnatifida
Torr. and Gray more hairy and somewhat dwarfed.

Besides Chrysopsis villosa Nutt. a mumber of other species become
so modified as to produce distinct varieties. Petalostemon violaceus
Mx. changes into its dwarfed but stouter variety tenuis Coulter, Owy-
buphus nyctagineus Sweet, becoming more and more hairy, finally pro-
duces the variety pilosus Gray (Barber County, Kans.). Ocnothera
Harticegt Benth. becomes the variety lavendul@folia Wats., dwarfed
and more hairy, and Aster oblongifolius Nutt. gives place to its dwarfed
but stouter and more rigid variety rigidulus Gray.

Just so, species with thickened or hairy epidermis and fleshy, narrow
leaves take the place of other species of the same genus farther west-
ward in the sandy or desert regions. Soon after passing the 95th
meridian we find Astragalus mollissimus Torr. and A. lotiflorus Hook.
taking the place of other species of the genus, and they finally become
the dominant astragali of southwest Kansas. These species are well
known to be quite hairy. In my own experience the latter species is
almost invariably the only one of the genus found in sand hills. As-
tragalus pectinatus Dougl. and A. pictus Gray, var. filifolius Gray, species
with very narrow or finely dissected leaves, and A. Parryi Gray, a
very hairy species, also become quite common, especially in eastern
Colorado. Lepachys Tagetes Gray becomes dominant in place of L.
columnaris Torr. and Gray in extreme southwestern Kansas, and Oxyba-
phus hirsutus Sweet replaces largely the other oxybaphiin the Neutral
Strip. Gaura villosa Torr, already begins to replace other gauras in
sand hills at Guthrie, Okla., and becomes quite common farther west-
ward. Solanum eleagnifolium Cay. becomes the dominant member of its
genus in southwest Kansas and Neutral Strip. It has very much thick-
ened whitish woolly leaves and epidermis. It also takes the place of
Solanum rostratum Dunal in furnishing food for great numbers of the
Colorado potato beetle in Barber County, Kans. Oenothera albicaulis
Nutt., with sparsity of leaves and much-thickened stem and leaves, and
Oc, pinnatifida Nutt., with finely divided leaves and hairy all over, be-
come common ib place of others of this genus in southwest Kansas and
southwestward. Gaillardia pinnatifida Torr., almost before one recog-
nizes the fact, appears in place of G. pulchella Foug., as the two species
resemble each other very much, but the former is really more ashy
pubescent, with leaves usually more finely divided. Artemisia filifolia

Torr. and A. Wrightii Gray replace other artemisias, and Dalea nana
Torr. and 2), lanata Spreng. are found common in place of other mem-
bers of that genus. All of these have either finely diszected leaves or
great woolliness, or both.

Of the sedges Cyperus Schiceinitzii Torr. seems to be the most com-
mon in sandy wastes. From what Dam able to learn from other sources,
however, it is a species that seems to be quite generally distributed
everywhere. In this connection it may be of interest to note a difference
in habitat between Cyperus Schiceiniteii Torr, and C. Houghtoni Torr,
which two species have only recently been separated by Dr. Britton.
(Bulletin Torr. Bot. Club, vol. xvii. p. 868.) T have noted both species
in many places all over the Southwest, and, while the former is quite
common in sandy wastes, [ have never once noted C. Houghtoni in
such localities.

Bouteloua hirsuta Lag. is the dominant grama grass in the Neutral
Strip; and in western Texas and eastern New Mexico the “black
grana” grass, B. eriopoda Torr., becomes quite common. Of the ferns
Cheilanthes Lindheimeri Hook. is a good example of a characteristic
western form. It is extremely villous to tomentose, found growing
in abundance among the rocks of the mesas in the Cimarron canons.

To name all other species characteristic of these sandy regions, taken
at random trom various genera and orders, would require a long list,
which would probably be both needless and uninteresting. Hence I
shall name only a few of the most striking examples: Heliotropium
convolvulaceum Gray, « species covered with stiff, appressed hairs,
which I have invariably found growing in almost pure sand; Red fieldia
feruoso Vasey, a grass with slender, rigid leaves, seemingly restricted
even to “blow outs” in sides of sand hills; Diplachne rigida Vasey, a
grass having, as the name implies, a very rigid, thickened stem and a
few short, narrow, rigid leaves; Hymenopappus flavescens Gray, a species
white tomentose, Common in southwest Kansas and Neutral Strip;
Franseria discolor Nutt., hispid hairy, in Seward County, Kans.; Polyp-
teris Texana Gray, Aplopappus rubiginosus Torr. and Gray, and A. divar-
icatus Gray, all viscid-pubescent or woolly, with rather narrow leaves;

rough, hispid, or tomentose, in southwest Kansas and southwestward;

It would seem to be a logical conclusion from the above facts that
any species introduced into cultivation for use as forage plants, in
these desert regions, ought to possess these same characters protecting
them against too rapid transpiration if there is to be any hope at all
of success without irrigation. Such grasses as Uniola latifola Mx.,,
or the cut-grass, Leersia oryzoides Swartz, for instance, would make
utter failures, Fortunately the plants proper for such regions can
usually be found among the native species, but if they must be intro-
duced from abroad they should certainly be selected from places similar
in soil and climate.

While the buffalo and grama grasses will probably continue to be,
for general purposes, the mainstay of the Western ranchman, at least
for many years to come, still it seems proper to note here a few other
species that might be introduced into cultivation with success by the
farmer, especially in the lower lands and river valleys, and that ought
to receive a thorough test by our Western experiment stations. The
United States grass station at Garden City, Kans., has probably
already made a trial of some of these species that I shall mention, but
I think not all of them.

Colorado blue-joint (Agropyrum glaucum BR, and 8.).—This is a very
common species in southern Colorado and in Neutral Strip and extreme
western Kansas. It makes excellent hay,and is one ofthe most valued
grasses in the Cimarron canons, How far it has been tested in culti-
vation I do not know, although I was informed that a ranchman of
southern Colorado had produced a very good meadow from the seed
obtained from a small plat raised the year before.

Broom grass (Andropogon saceharoides Swartz, and varieties),—A
ranchman at Garrett, Okla., calls this and the following species
the best grasses they have in the Cimarron canons, and others have
made similar statements, It is widely diffused all over the Southwest,
from Wichita and Guthrie westward, but not very abundant, although
increasing in abundance westward,

Panic grass (Panicum obtusum HBK.).—Sofar as I know, this grass
has never yet even been mentioned as one worthy of cultivation; but,
as far as its being relished by stock is concerned, experience points it
out as an excellent grass, both for hay and grazing. Its actual nutri-
tive value, of course, would have to be determined by chemical analy-
sis. It affords a fair supply of foliage, large spikelets which ought to
furnish good seed, matures rather early, and seems well adapted to the
river valleys of the Plains. It ranges from Kingfisher westward, be-
coming rather common in the Neutral Strip.

Halls broom grass (Andropogon Hallit Hack., and varieties).—This
is quite stemmy, but furnishes good grazing and, if cut young, pro-
duces a good quality of hay. It is much like the common blue-stem
(Andropogon provincialis Lam.), and is quite frequent in cations as
well as on uplands.

230

Switch grass (Panicum virgatum L.) is also a common and well-
known grass in the canons. The value of this grass for hay is also
increased by early mowing. It is called a very good forage plant by
the ranchmen.

Yellow jfoxtail (Setaria glauca Beauy.).—The ranchmen in the South
Canadian canons call this a very good grass for hay. Ihave seen them
mowing it in considerable quantity. It is rather common there. It
may possibly seem the more valuable simply because there is a lack of
other good species,

PLANTS CHARACTERISTIC OF GYPSUM TILLS,.

It seems to be pretty well understood that the meaning of the Indian
word Oklahoma is “ home of the red earth” (Okla=red, homa=home) ;
which, if true, makes it a very appropriate name, since a large portion
of the Indian Territory north of the South Canadian River is plainly
distinguished by outcropping “red beds,” which also extend north-
ward into Barber, Pratt, Comanche, and Kingman counties, Kans.

Now, gypsum and salt are also associated with the ‘red beds,” out-
cropping at the surface in the form of gypsum hills and salt marshes,
especially along the valley of the Cimmarron and in eentral Kansas.
The gypsuin deposits, being a little harder than the surrounding soil,
have been left standing by the eroding action of streams until they
have become very prominent hills, in some places forming what are
called glass mountains, from the glistening appearance of the mica-like
gypsum covering their sides.

All these gypsum hills invariably have their characteristic plants.
The special characters of the plants are very much the same as those ot
the plants of sandy regions. This is explained by the fact that they
have to contend with the same general adversities of environment—a
dry, gravelly soil, from which the water is rapidly drained away through
the sides of the hilis.

At the summits of these hills, near Kingfisher, Okla., certain species
are found which do not occur in the surrounding lower country within
a radius of 100 miles, so far as my experience goes. Of these, Riddellia
tagetina Nutt. is one of the most common, found on various hills along
the Cimarron River. The dwarf form of Oenothera serrulata Nutt., al-
ready mentioned, is also quite as common, as well as Oc. Hartwegi
Benth., Gaura villosa Torr., Yueca angustifolia Pursh, Gilia longiflora
Don., Mentzelia nuda Torr. and Gray, and M. oligosperma Nutt., are
frequent on gypsuin hills from Caldwell to Barber County, Kans. Port-
ulaca pilosa L, occurs on similar hills in the Cherokee Outlet, Ind. T.

The following species I have not seen in other localities than gypsum
hills: Lesquerella gracilis Wats., Nama demissum Gray, and Astragalus
microlobus Gray, in Cherokee Outlet, and Oxybaphus nyctagineus Sweet,
rar, ptlosus Gray, in Barber County, Kans. I suppose, however, they
may be found, in other places. They are not very common, and this

231

fact nay possibly account for my not having seen them in other local-
ities. Of course it is not necessary that any species should be entirely
limited to a certain locality in order to be properly characteristic of
that locality.

PLANTS CHARACTERISTIC OF SALT MARSHES.

Experiments have shown that solutions of salt have a retarding influ-
ence upon the assimilative processes in plants; and now in arecent con-
tribution to botanical science (Ueber Schutzmittel des Laubes gegen
Transpiration besonders in der Flora Javas,” A. #. W. Schimper; Sitz-
ungsberichte der Berl, Akadem, der Wissenschaften, 1890, 8S. 1045), the
writer maintains that the presence of salt also interferes with the water
supply, much to the same extent as a relatively dry soil. Hence it is
argued that the thick, fleshy leaves, sunken stomata, and hairiness of
salt-marsh plants are all protective characters against too rapid trans-
piration, just as they are in the case of plants of desert regions. If this
view is correct, there are probably other characters distinguishing salt-
marsh plants from those of desert regions, for I have yet noted but two
species that are at all common to both localities.

The two species that I have found to be common to salt marshes and
barren sandy regions are Corispermum hyssopifolium L. and Cycloloma
platyphyllum Moq., belonging to the goosefoot order (Chenopodiacee),
The former I have collected in abundance in sandy districts in Texas
Panhandle and various places in southwest Kansas and in salt
marshes all along the Salt Fork, in Cherokee Outlet; the latter, in a
number of Kansas salt marshes, and in sandy wastes in extreme south-
western Kansas, where it is a common tumble weed.

Atriplex expansa Wats., belonging to the same order to which the
above belong, is a common alkali and salt marsh plant in southern
Kansas, although this is its first publication as a Kansas plant. It is
also common along the Salt Fork in Indian Territory. It is well known
to possess thick, scurfy leaves. Mochia Americana Wats., another mem-
ber of the goosefoot order, and possessing unusually thick, terete,
tleshy leaves, is also a common salt-marsh plant throughout southern
and western Kansas. I have myself found it at Wichita and in salt
marshes at Geuda Springs (Sumner County) and in Stafford County.
It is according to my experience that a majority of the genera of the
orders Chenopodiacere and Amarantaceze represented in the Great
Plains furnish species peculiar to salt marshes and sandy wastes,

Of the sedges Scirpus maritimus L. and Scirpus Torreyi Olney are
invariably found associated with salt marshes throughout Kansas and
Indian Territory. Distichlis maritima Raf., var. stricta Thurber, and
Sporobolus airoides Torr, are such common grasses in salt marshes that
it would be quite strange to see a salt marsh without them. The latter
is also found in various alkaline and other barren soils,

6654—No, 6——4

232

Sesuvium portulacastrum L., belonging to an order (Ficoidew) char-
acterized by fleshy, succulent plants, is very frequent in Kansas salt
marshes and on the Great Salt Plain of the Cimarron, and is strictly
characteristic of such localities, according to my observations. Glawx
maritima L.is also reported from Kansas and known to be a character-
istic salt-marsh plant. I have not observed it myself.

Neomella angustifolia Torr. is common in alkaline soils, but not at
all limited to such localities.

PLANTS CHARACTERISTIC OF SANDSTONE OUTCROPS.

In the central and eastern portions of the Indian Territory are small
surface outcrops, usually of sandstone, at the summits or on sides of
hills, or even scattered over the general level of the country, which are
always clothed by a vegetation entirely distinct from that of the sur-
rounding soil. But I have only observed this peculiarity in the Indian
Territory, and probably have not yet the required facts to make it a
matter of very much importance.

I shall name a few of the species most striking]y characteristic of
these localities that have come under my observation. These outcrops
are especially noticeable about Guthrie and Oklahoma City, where I
have collected the following species: Nama hispidum Gray, Evax proli-
Jera Nutt., Euphorbia peplidion Eng., Linum Berlandiert: Hook., and
several others of less importance. In these same outerops and in the
eastern part of the Territory I have collected some others, which are
also found in the western Great Plains, such as Actinella linearifolia
Torr. and Gray, and Evolvulus argenteus Pursh, both at Oklahoma City,
and (nothera linifolia Nutt., Rumex acetosella L., Phacelia parviflora
Pursh, Phacelia strictiflora Gray, and others, in the Creek Nation.

NOTES ON SOME PACIFIC COAST GRASSES,

By GEORGE VASEY,

The grasses of California as described by Dr. Thurber in the Botany
of California, second volume, are mostly models of accurate description.
In some cases, however, and especially in the genera Poa and Festuca,
Dr. Thurber in his conservative desire to make as few new species as
possible made mistakes in trying to fit many really good new species
to old names. I have been well satisfied of this for several years, but
having recently had an opportunity of studying some of these grasses
in the herbarium at Kew and in that of the British Museum, I am com-
pelled to make several important changes. It appears to me that Dr.
Thurber gave too broad definition to the genus Atropis (Puccinellia
Parl.). The first and second species of his list probably belon g in
that genus, but A. california, tenuifolia, paucifilora, and probably sca-
brella are, in my opinion, forms of Poa.

Poa abbreviata R. Br. Chloris Melv. 287 (1823), is a truly arctic grass, as noted
hereafter, on page 270 under Poa confinis.

Poa stenantha Trin. Mem. Acad. St. Pet. ser. 6. i. 376 (1831) is an Alaskan species
which has not, so far as I can find, been collected in California or in Washing-
ton, and the plant described by Dr. Thurber under that name is a very different
species. It is probably Festuca nervosa Hook., which, however, is not a Festuca,
but a Poa. I saw Hooker's type in the Royal Herbarium at Kew, and am satis-
fied that it should be Poa nervosa (Hook.) Vasey. See description on page 274.

Poa glumaris Trin. Mem. Acad, St. Pet. ser. 6. i. 379 (1831). It is evident that
Dr. Thurber, in Bot, Cal. ii, 313, has confused this grass with Poa kingii Wats.
Bot. King Surv., which is Festuca confinis Vasey, Bull. Torr. Club, xi. 126, and
which would have been named Festuca kingii if its identity had been known
at the time of its second publication. The two grasses are entirely distinct.
Festuca confinis occurs throughout the Rocky Mountains, where Poa glumaris has
not been found. P.glumaris, however, appears to be confined to the coast, and
has not been collected so far south as Washington on the west side, but it occurs
about Hudson Bay, in Labrador, in the islands of the St. Lawrence, and in
Newfoundland.

Eragrostis alba Presl, Rel. Haenk. i. 279 (1828), None of the Californian specimens
which I have seen under this name answer the description of Presl, but appear
to be forms of the very variable EF. purshii.

Festuca L. There are several good species of this genus in California which must
have new names. The F. gracillina of Hooker, to which Dr. Thurber referred

265

266

one of them, is a South American grass of which I have seen authentic specimens
in the Kew Herbarium and elsewhere, and is very different from the Californian
plant, which I have named F. viridula. See description on page 279.

Festuca scabrella Torr. Bot. Cal. ii. 318 (1880), Dr. Thurber has here included at
least two species. Neither of them appears to be the true scabrella as described
and figured in Hooker’s Flora Boreali-Americana, which is rather sparingly
represented in our herbarium by specimens from British America, Montana,
Colorado, and the mountains of the Gaspe, Lower Canada, What is probably
a large variety of this species occurs in eastern Oregon and Washington, variety
major. (See page 278.) Another species described under this name is a stout, tall
grass of California and Oregon, which I have called F. californica. See descrip-
tion on page 277.

Festuca pauciflora Thunb. Fl. Jap. 52 (1784). The grass which Dr. Thurber
described under this name is not that plant, as I ascertained by examination of
the true F. pauciflora inthe herbarium at Kew. The Californian plant described
includes Festuca occidentalis Hook., and perhaps one or two other species.

It is difficult at the present time to decide as to the Hookerian species. The
original description says: “Leaves principally radical, one-fourth the length
of the culms, 3 or 4 on the culm, distant, but the culm is almost wholly concealed
by their remarkably long, sheathing bases. Panicle 5-6 inches long; branches
slender, again divided, more or less long, and more or Jess patent. Spikelets
small in proportion to the size of the panicle, green, glossy, smooth. Awns
about equal in length tothe perianth [floral glume]. Glumes short and obtuse,
especially the upper or inner one, which is about twice as long as the outer one,
yet not half so long as the floral valves. Inner valves [palet]} of the floret as long
as the outer, acute, flat at the back, but the margins closely inflexed.” The
description also says: ‘‘ Leaves, very narrowly linear-filiform;” also: ‘‘Glumes
small, very unequal, obtuse and ciliate at the apex.” Dr. Thurber, in Bot.
Cal. ii. 318, has considerably modified the description, comments on the “ ob-
tuse” glumes, and refers tospecimens communicated to the Torrey herbarium by
Sir William Hooker, in which the glumes “ would hardly be called obtuse.” I
have examined the specimens referred to, as also others in the Kew herbarium,
and think they are some of the forms of Festuca ovina or rubra. One of the species
which was probably included in Dr. Thurber’s description of I. pauciflora
Thunb. is what I have elsewhere described as Festuca jonesii. Another, which
may also have been included under that name, is Festuca ambigua, described on
page 277.

Elymus sibiricus L. Sp. Pl. i. 83 (1753). The species described by Dr. Thurber
under this name is not the Linnwan plant,and is hereafter described as Z.
glaucus variety tenuis. (See page 280.)

DESCRIPTIONS OF NEW OR NOTEWORTHY GRASSES FROM THE UNITED
STATES.

By GreorGe VASsEY.

Stipa hassei sp. nov. Culms very slender and wiry, densely tufted, more or less
branching below, erect, 12 to 15 inches high; leaves narrowly linear, thread-
like, setaceous, not rigid, 4 to 8 inches long, erect; ligule inconspicuous; upper
leaf reaching nearly to the panicle; sheaths narrow, close, striate; panicle 2 to
3 inches long, narrow, loose, erect, slender; branches erect, mostly 2 or 3 together,
unequal, the longer ones an inch or more in length, naked below, the others
flowering to the base; spikelets small; empty glumes narrowly linear-lanceolate,
acuminate, about 2} lines long, nearly equal, the lower 1-nerved, or indistinctly
3-nerved below, the upper strongly 3-nerved ; floral glumes nearly as long as the
empty ones, narrow, tapering tothe apex, membranaceous (thinner than in most
species of the genus), with 3 principal nerves, smooth; stipe short, with a few
short hairs; palet one-half as long as its glume, acute; lodicules } to 4 line long;
awn of the floral glume 8 or 9 lines long, bent above the middle, twisted below,
nearly smooth; grain oblong, about 1 line long.

Dry ridges near Santa Monica, California. Type specimen collected in 1891 by
Dr, H. E, Hasse, for whom it is named. It is nearly related to Stipa eminens
variety andersoni Vasey, which is found in the same region.

Orysopsis hendersoni sp. nov. Culms densely cespitose, 6 to 8 inches high; leaves
crowded at the base, conduplicate, pungent, scabrous, rigid, one-half as long as the
culms, lower sheaths rather loose; panicle 2 to 3 inches long, narrow, the branches
mostly erect in pairs, the lower L to 2 inches long, naked except the 2 to 4 flowers
near the apex; spikelets 2 lines long; empty glumes a little longer than the
floral ones, broadly oblong, obtuse and toothed at the apex, the lower 3-nerved,
the upper 5-nerved, both scarious above the middle; floral glume linear-oblong,
nearly 2 lines long, smooth, coriaceous, obscurely 5-nerved, the apex formed of 2
lateral teeth, which appear to be on one side, the caducous, simple, curved awn
5 or 6 lines long, arising between the apical teeth; stamens 3, barbate.

Type specimen collected in Washington by L. F. Henderson, in 1892 (No. 2249).
Itis similar in appearance to O. webberi (Thurb.) Vasey and to small forms of 0.
exigua Thurb., but may be readily distinguished from either by its smooth florets.

Muhlenbergia filiculmis sp. nov. Culms tufted, weakly erect, filiform, 7 to 10
inches high, leafless except near the base; radical leaves numerous, setaceous-
filiform, 1 to 1} inches long; sheaths very short, the lower ones loose; ligule con-
spicuous, narrow, | line long; panicle spike-like, narrow, 1 to 14 inches long,
the upper branches short, alternate, the lower ones inserted singly or in twos,
naked near the base, each with 3 to 5 spikelets; spikelets small, 1 line or more
long, with an awn about 4 line long; empty glumes very thin, half as long as
the floral glumes, the lower one ovate, acute, the upper broadly ovate, with 3
to 5 teeth at the apex; floral glumes oblong-linear, sparsely pubescent below,

267

268

8-nerved, with an awn about } line long; palet equaling its glume and nearly as
wide.

Type specimen collected by C.S8. Sheldon on sandy soil, Ute Pass, Green Moun-
tain Falls, El Paso County, Colorado, at 8,500 feet altitude, August 2, 1892 (No.
321). This species 1s nearest to M. gracilis variety breviaristata Vasey, but is more
slender, with shorter leaves, shorter glumes, and shorter awns.

Sporobolus ligulatus Vasey & Dewey sp. noy. Perennial from a knotted root-
stock; culms slender, smooth, simple, 12 to 18 inches high; basal leaves numer-
ous, narrow, 1 line wide, 4 to 12 inches long, flat or convolute, scabrid or nearly
smooth; culm leaves 2 or 3; sheaths equaling or exceeding the long internodes,
the upper one extending nearly to the panicle; ligule 2 to 4 lines long, lacerate;
panicle 4 to6 inches long, narrow, erect or nodding, dark green; branches mostly
single, erect or spreading, hispid, spikelet-bearing nearly to the base, + to %
inch long; spikelets 14 to 2 lines long, narrow, subterete; empty glumes broadly
lance-ovate, obtuse, nerveless, dark green, one-half as long as the floret, the
second slightly larger; floral glume lance-oblong, subobtuse, smooth, 3- (or
obscurely 5-) nerved; palet like the glume in texture, color, and size, with a nar-
row, obscure, membranaceous, marginal wing (usually involute) on each side of
the apex.

Type specimen in the United States National Herbarium; collected by G. C,
Nealley in Limpia Cafion, Presidio County, Texas, September, 1892 (No. 127).
It is most nearly related to S. jonesii Vasey, but may ‘be readily distinguished
by its leafy culm and larger spikelets.

Calamagrostis arctica Vasey, Il]. N. A. Gr. ii.55 (1893). Perennial; culms from a creep-
ing rootstock, decumbent below, 6 to 10 inches high, the base covered with persist-
ent, open, leafless sheaths; radical leaves rather rigid, 2 to 3 inches long, flat,
smooth, 2 to 3 lines wide, the 1 or 2 cauline leaves with long, loose sheaths, smooth,
the blades erect, flat or folded, about 1 inch long; ligule acute, 1 to 14 lines
long; panicle spike-like, about 1 inch long, rather dense; the short branches
spikelet-bearing to the base; spikelets 2 to 2} lines long, purplish; empty glumes
ovate-lanceolate, attenuate-pointed, scabrous on the keel and nerves, the first
1-nerved, the second 3-nerved; floral glume elliptical-oblong, acutely 4-toothed
at the broad apex, 4-nerved, about 2 lines long, the awn from near the base, 2}
to 3 lines long, and extending conspicuously beyond the empty glumes; palet
lanceolate, acuminate, 2-toothed at the apex, about equaling the floral glume;
hairs of the callus and pedicel one-fourth as long as the floret.

Type specimen collected by J. M. Macoun, in 1891, at St. Paul Island, Bering
Sea (No. 38). It bears some resemblance to C. montanensis Scribn., but is read-
ily distinguished by the broader leaves and the short, purple panicle.

Bouteloua rothrockii sp. nov. Perennial, culms tufted, 15 to 20 inches high,
erect, simple or sparingly branched, leafy nearly or quite to the panicle; leaves
narrow, thinly pubescent near the base, 2 to 5 inches long; ligule short, ciliate;
panicle 3 to 7 inches long, consisting of 5 to 9, nearly straight, erect, spreading
or recurved spikes, which are commonly 1 to 14 inches distant, 1 to 14 inches
long, and 2 lines wide, densely flowered; spikelets (including awns) 2 to 24
lines long; empty glumes unequal, oblong, mucronate or acute, the upper
about 1 line long, the lower one-half as long; floral glume oblong, 4-lobed to
the middle, villous on the nerves below, ciliate on the margins and apex, the
awns from the sinuses one-half longer than the glime; palet nearly as long as
its glume, wedge-oblong, 4-toothed or lobed above, with the two nerves ex-
tended into short awns; sterile pedicel hairy-tufted above, with 2 or 3 imper-
fect florets, and 3 awns as long as those of the perfect floret.

Type specimens collected at Cottonwood, Arizona, by Dr. J. 'T. Rothrock, in
1874 (No. 347), and distributed with Pringle’s Arizona collection of 1884 as B, poly-
stachya variety major Vasey. It is also found in New Mexico and northwestern

269

Mexico. Ut is readily distinguished from B. polystachys Benth. and B. micro-
stachys (Fourn.) Vasey by its perennial, upright habit and the longer spikelets.
All the lobes and the awns of the floral glumes are much larger than in B. poly-
stachys, and the lateral lobes are larger than in B. microstachys.

Sieglingia wrightii sp. nov. Dimwcious; culms erect or decumbent, from strong,
creeping rhizomes, simple or branching, 1} to 2 feet high, leafy, rather stout;
leaves of culm 5 to 8, those of the fertile culms 6 to 12 inches long, 2 to 3 lines
wide, attenuate; lower sheaths shorter than the internodes, loose, smooth, the
upper one near the panicle and equaling or exceeding it; pistillate panicle 5
to 8 inches long. linear-oblong, the brauches mostly single, appressed, or the
lower ones somewhat spreading, 2 inches long, spikelet-bearing throughout,
somewhat spike-like, simple or compound at the base; spikelets large, 5 to 8
lines long, compact, nearly terete, 5- to 7-flowered, florets closely imbricated;

margined ani ciliate-scabrous; styles 2, thick, protruding fromthe apex of the
infolded palet; ovary not matured in the specimens seen; staminate plants as
seen mostly smaller, with shorter and narrower panicles, shorter, compressed

It was first collected in Texas or New Mexico by C. Wright and is No. 2038 of
his collection, distributed as Tricuspis albescens Munro, from which it is very dif-
ferent. It has since been collected (in 1891 and 1892) in Presidio County, Texas,
in two distinct localities by Mr.G.C. Nealley; one of the localities furnishing
staminate plants and the other pistillate. Itis the only diccious species known
in the genus, and differs from the usual generic characters in wanting the lateral
teeth of the floral glumes and the pubescent lateral nerves and callus, and in the
very large cylindrical spikelets and large florets. Still its affinities seem to be
withthe genus. The staminate form has been described as Poa texrana Vasey,
Contr. Nat. Herb. ii. 60 (1890).

Eragrostis orcuttiana sp.nov. Apparently annual, culms 2 to3 feet high, nearly
simple, or branching below, smooth, rather stout; leaves flat or becoming some-
what involute, 3 to 6 inches long, 2 to 3 lines wide, acuminate, scabrous on the
margins; sheaths shorter than the internodes, smooth; ligule very short, ciliate;
panicle spreading, 7 to 11 inches long, when expanded triangular in eutline;
general rachis smooth, without hairs at the axils; branches scattered or the

pound, very floriferous; spikelets lead-colored, on capillary pedicels mostly
shorter than themselves, narrowly linear, about 3 lines long, 7- to 9-flowered;
empty glumes purplish, lanceolate, acute, shorter than the floral glumes, which
are about 1 line long, acute, the lateral nerves prominent; palet slighty shorter
than the glume, narrow, 2-toothed at the apex, finely scabrous on the keel.

Type specimen collected at San Diego, California, by C. R. Orcutt, in 1885 (No,
1313), and others at San Bernardino, California, by 8. B. Parish. Well distin-
guished by its large, many-flowered panicle and slender spikelets. It is most
nearly related to /, mericana Link.

Melica inflata sp. nov. Culms bulbous at the base, rarely cespitose, 3 to 6 feet high,
erect, terete, smooth, and leafy; leaves 6 to 10 inches long, 1 to 2 lines wide; ligule

270

floral glumes oblong-lanceolate, scabrous, about 4 lines long, subacute, the mid-
dle nerve shortly excurrent; palet one-third shorter, obovate-oblong, somewhat
scabrous, ciliate above,

This is very nearly the description of Bolander under Af, powoides variety inflata
(Proc. Cal. Acad. iv, 101, 1869), and corresponds to his specimen numbered 6121
as referred to by him, It appears to be a good species, but was apparently
overlooked by Dr. Thurber. His specimens were collected in the Yosemite Val-
ley in 1856, and are the only ones I have seen except a few collected by Mr. J. G.

Lemmon in 1889, near Mount Shasta, in northern California.

scarious at the apex, obscurely 5-nerved; palet as long as its glume, sparsely
pubescent on the keels and back; grain lance-oblong slightly triquetrous, about
+ line long.

Type specimen collected by G. R. Vasey at Socorro, New Mexico, in 1881; other
specimens collected in Utah, Colorado, Kansas, and northward to British Amer-
ica. This is P. andina Nutt., in Herb. Phila, Acad., fide F. Lamson-Scribner,
but Nuttall’s manuscript name is preoceupied by a Chilian species, P. andina
Trin. It may be distinguished from Poa fendleriana (Steud.) Vasey by the
smaller spikelets, smaller florets, and the pubescence between the nerves of the
floral glumes.

found in the arid districts from Texas to Lower California and northward to
Colorado and Utah, springing up abundantly after the summer rains. It differs
from Poa annua L. in the narrow panicle and the presence of a web at the base
of the florets. Ina few instances it hasbeen distributed as Poa annua variety
stricta Vasey, The name P. bigelorii, without description, is given in Vasey,
Descr. Cat. Gr. 81 (1885),

Poa confinis Vasey, Ill. N. A. Gr. ii. 75 (1893). Apparently dicecious; culms from a

and Alaska. This has been taken for Poa abbreviata R. Br., which isa truly Arctie
grass, 3 to 4 inches high, with the onter glumes longer, the floral glumes silky
pubescent below and woolly-tufted at the base. [had an opportunity of studying
the types of that species in the British Museum, and was satisfied of its difference

The type of this species is described and figured as Festuca nervosa in Hooker,
Fl. Bor. Amer. ii. 251 (1840), and is an unusually loose-flowered form. This form
was re-collected in 1871 near Portland, Oregon, by Elihu Hall, and Dr. Gray,
in his determination of Hall’s collection (Proc. Amer. Acad. viii. 409), referred it
to Poa stenantha Trin., from which it really differs in many respects, as shown
by specimens from the St. Petersburg herbarium and by many corresponding speci-
mens since collectedin Alaska. Dr. Gray also thought it probable that this was
Poa leptocoma Trin., and Grisebach (Flora Rossica, iv. 373) places Poa leptocoma
Trin, under Poa stenantha Trin, as a variety; but from descriptions and typical
specimens from the herbarium of St. Petersburg I am convinced that both of
those species are different from Poa nervosa (Festuca nervosa Hook.), The
species as above described occurs in northern California, Oregon, Washington,
Idaho, and Montana.

Orcutt, in 1884 (No, 1070); also found near Vallecito, northern Lower California,
by C. R. Orcutt (No. 1440). The linear spikelets with rigid glumes give the pani-
cle the appearance of an Atropis.

Peak, Colorado, in 1885. It grows at high altitudes on margins of streams, usu-
ally in wet, sandy or gravelly soil. Rocky Mountains, Colorado, northward to
Montana, Washington, and British America. The long, smooth, reflexed capil-
lary branches are characteristic of this species, and distinguish it from Poa
arctica R. Br. with which it has been confused. A small form of P. reflexa is
represented in Vasey, Ill. N. A. Gr. ii. Fig. 4, Pl. 71. The name without de-
scription appears in Vasey, Descr. Cat. Gr. 83 (1885).

on the keels; internode of rachilla puberulent, 4 line long.

Collected by J. H. Sandberg near Lewiston, Idaho, in 1892 (No. 164). Also
found by other collectors in Washington and California. It approaches some
forms of Poa tenuifolia Nutt., from which it raay be distinguished by its smaller
spikelets, shorter florets, and more pubescent floral glumes.

As will be inferred from the description, there is considerable variation in
this species. The typical plant is always either alpine or found in high lati-
tudes, especially in the Rocky Mountains, the White Mountains, or the Arctic
regions. The Norwegian specimens are shorter than ours, with less dense spikes.

specimens have been collected in the Rocky Mountains at lower altitudes than
the species; also in the White Mountains and on the high plains of the West,
and of British Columbia. Some specimens seem to run into A. caninum (L.) R&S,
Most of these plants look very different from the type; some have been distrib-

eastward to Arizona and Utah. Chiefly distinguished from the type by its nar-
rower leaves and its weaker and fewer-flowered spikes. LE. sibiricus L., to which
Dr. Thurber referred our plant, is larger, with a more lax, bending spike, having
larger spikelets and much more diverging and longer awns,

Chloris longifolia (Fourn,) Vasey. Gymnopogon longifoliusFo urn. Mex, Pl. ii. 144
(1886). Culms 1} to 2} feet high, rather stout, leafy, crespitose, bearing at
the base numerous branching seed-bearing stolen-like panicles sometimes 6
inches long; leaves 6 to 10 inches long, flat,3 to 4 lines wide, scabrous on the
margins and upper surface, longer than the internodes, the lower ligules ciliate
to pilose; apical panicle 5 to 8 inches long, of 5 to 10 racemose spikes erect at
first, then spreading, usually in threes below, the others irregularly scattered,
narrow and spikelet-bearing to the base; spikelets somewhat imbricated above,
becoming more distant, but approximate below, one-sided, with one perfect and
one sterile floret; empty glumes unequal, the lower minute, subobtuse, the upper
one less than 1 line long, ovate, acute or acuminate, purplish, scarious-margined ;
floral glume linear, 2} to 3 lines long, with a distinct hairy callus at the base, and
finely scabrous on the midnerve near the apex, otherwise smooth, with two short
teeth at the apex, and between the teeth a scabrous awn 3 to 4 lines long; palet
as long as its glume, terminating in 2 slender acute teeth; imperfect floret pedi-
cellate, 4 to 1 line long, linear, with an awn about 2 lines long; grain linear-
oblong, the hilum occupying one third its length. The panicles at the base of
the culm are numerous, from 2 to 6 inches long, and irregularly branched, These
seem to run on or near the surface of the ground, and here and there give rise
to fertile florets, which are larger than those in the aerial panicle, and with a
larger, rounder grain; the fertile florets about 3 lines long, oblong or oval, with
an abrupt point; empty glumes nearly equal, ovate, about 2 lines long, many-
nerved; floral glume oval, thickish, acute, nearly as long as its palet; grain ob-
long, abruptly pointed, about 2 lines long, much longer and heavier than the
grains of the panicle, the hilum occupying one-half its length. I have not ob-
served any stamens in the florets of the stolons.

Collected at Ymala, Sinaloa, by Dr. Edward Palmer, in September, 1891 (No. 17638).
I have no doubt that this remarkable grass should be placed in the genus Chloris,
It is unusual in the racemose disposition of its spikes, they commonly being verti-
cillate or digitate at the summit of the peduncle, but in Chloris verticillata Nutt.
there is a form with two or three verticillate somewhat distant whorls of spikes.
Fournier, in his account of Mexican gTasses, gives 6 species of Chloris, all dif-
ferent from this. He, however, gives two species of Gymnopogon, one of which
from the description given may be our grass, inasmuch as he remarks that the
empty glumes in the species he describes are smaller than in the type of the
genus. I have not seen any specimens of the species he describes, but our plant
is excluded from Gymnopogon by the spikes being regularly floriferous through-
out, instead of being interruptedly floriferous, and also in the greater develop-
ment of the second floret. There is no mention in any account of the species
of Chloris, nor of the tribe Chloride, of the floriferous stolons at the base of
the culm. The only analogous case that I know of is that of Amphicarpum, a
grass of the pine barrens of New Jersey and extending to Florida, in which
there are similar but less branching runners, bearing fertile florets, those of
the upper panicle being all sterile, while our plant has perfect seeds on the
upper panicle as well as on the lower panicles.

does not answer the description; neither does the Californian species, so called
by Dr. Thurber, which is quite different from the present species.

inch wide, the nearly sessile branches densely crowded, interrupted and distant
below, also on the same plant some panicles open and thinly flowered; spike-
lets linear, 3 to 4 inches long, 7- to 13- flowered or on less perfect culms re-
duced to 5, 3, or 2; outer glumes ovate, subacute, similar in texture to the floral
glumes, which are ovate-lanceolate, rather thick, subobtuse, smooth, the lateral
nerves not prominent. |

Collected at Manzanillo (No. 1335) by Dr. Edward Palmer, March 2 to 18,

DESCRIPTIONS OF FOUR NEW PLANTS FROM TEXAS AND COLORADO.

By J. M. Hotzincrr,

Claytonia bodini sp. nov. Cauline leaves two, opposite, terete, fleshy; a lanceolate,
leaf-like, recurved bract opposite the first pedicel of the raceme; raceme 5- to 10-
flowered ; lower pedicels much elongated, 1.3cm. long; pedicels in fruit drooping;
fruiting sepals 1.3 cm. long, much surpassing the capsule, narrowly acuminate,
persistent, little spreading after anthesis; petals longer than the sepals, nar-
rowed upward, but with rounded apex.

Collected at Hempstead, Texas, in 1892, by J. E. Bodin.

Near C. virginica. The corm was not sent with these plants,

Baptisia lanceolata texana var. nov. Plant smaller than the type; leaflets wider
and shorter, 1.6 cm, wide, 4 cm. long, or less; branches and internodes shorter;
flowers 2cm.long. In the typical form of the species the leaflets vary from 1.5 to
3cm. in width, and from 6 to 10 cm. in length, and the flowers are 2.5 cm. or more
long. The pubescence, including the ovary, the sessile leaves, and the nearly
sessile solitary flowers in the axils of the upper leaves of the flowering branches,
which are terminated by few-flowered racemes, associate this plant closely with
Baptisia lanceolata,

Collected in Texas by G, C. Nealley in 1889 (No. 73).

Stemodia schottii sp.nov. <A low and diffusely branched perennial herb, 10 to 15
em. high, woody at the base; the entire plant, including branches, leaves, and
outside of calyx and corolla, beset with minute, stipitate glands, probably mak-
ing the plant viscid when fresh; internodes 1 to 2 cm. long; leaves sessile, wedge-
shaped and slightly auricled at the base, but not connate, the margin above the
entire basal part cut into a few coarse serratures, the apex obtuse; flowers single
in the axils of the upper leaves; pedicels 3 to 5 mm. long, bibracteate under the
flower; calyx lobes narrowly linear, about as long as the pedicel, a little longer
than the similar bracts; corolla 12 to 14 mm. long, the tube dilated upward, blue
at the limb, yellow on the under side and toward the base of the tube, the inside
somewhat hairy, the large upper lobe outermost; stamens didynamous, the
longer pair reaching the small notches in the limb; anther cells borne apart by
aconnective fully as long as the anther, becoming peltate after pollination; a
rudiment of a fifth stamen present; ovary and style included; stigma single,
somewhat dilated; capsule when ripe little shorter than the calyx lobes, splitting
into four valves, leaving the pitted placent in the axis; seeds small, oval, 0.3
mm. long, minutely hispid in lines.

Habitat, southern Texas, along the RioGrande. Collected by Dr. A. Schott, at
Rio Grande, Texas, in 1853; and by G.C, Nealley, at Comstock, Valverde County,
Texas, in 1889 (No. 305). Dr.Schott’s plant had been distributed as Conobea
multifida.

OXYBAPHUS BODINI Holzinger.

287

Oxybaphus bodini sp.nov. Plant 5 to 13cm. high, diffusely spreading, the
branches diverging nearly at right angles; stem whitish, as in some other
species of this genus, glabrous to the naked eye, but under the lens minutely
roughened by short hairs with points turned upward; internodes 1.3 cm. long
or less; leaves long-linear, fleshy-leathery, drying as if terete, glabrous; flowers
solitary in the axils of leaves toward the upper part of the stem, on pedicels much
shorter than the involucre; these, with the involucre, covered with short, stiff, ap-
pressed hairs; involucre smaller, of firmer texture, and more deeply lobed than
in O.angustifolius Sweet, which is suggested by the somewhat similar fruit as
the nearest allied species. These characters, with the diminutive size, dis-
tinguish this plant.

LIST OF PLANTS NEW TO FLORIDA,

By J. M. HoLziIncer.

Mr. J. H. Simpson was employed by the Department of Agriculture
in 1891 and 1892 to collect plants in southern Florida. Among the
many interesting species found by him are the following introduc-
tions and additions to our Southern flora:

Achyranthes aspera obtusifolia Lam. Strait of Florida, side of Key West,
Simpson (No. 205).

Alternanthera paronychioides St. Hil. Key West, Simpson (No. 357).

Argithamnia fendleri Miill. Key West, Simpson (No. 316).

Cassia grammica Spreng. No Name Key, Simpson (No. 194).

Colubrina reclinata Brogn. Long Island, Simpson (No. 427 ); southern Florida,
Curtiss (No. 473),

Crescentia cucurbitina L. Southern Florida, Simpson (No. 450). (Vide Gray, Syn.
F 1, ii. pt. i. 456.)

Cuscuta umbellata H. B. K. Southern Florida, Simpson (No. 361).

Epidendron rigidum Sw. Florida, Curtiss (No. 1708). Communicated to the Na-
tional Herbarium by Professor 8, M. Tracy.

Euphorbia pilulifera procumbens Boiss. Elliott Key, Miami and Cedar Key, Simp-
son (No, 505); southern Florida, Garber; Indian River, Curtiss (No. 2496). Dis-
tributed as LF. pilulifera L.

Talinum patens Willd. One plant was sent in by Mr. Simpson from southern
Florida.

Tamarindus indica L. Key West, Simpson (No. 348). Mr. Simpson says of this:
“Tt grows on dry, rocky hammock soil, mostly in the brush in uncleared land.
Trees 20 to 30 feet high and from 12 to 18 inches or more in diameter. There
were not many specimens, but enough to show that the species is naturalized at
Key West, and should be admitted into our flora.”

RANUNCULUS COOLEYA Vasey & Rose.

DESCRIPTIONS OF THREE NEW PLANTS.

By J. N. Rose.

Ranunculus cooleyz Vasey & Rose sp. nov. Glabrous, with a slender caudex
bearing many long fibrous roots; scape, 1- or 2-flowered, naked or bearing @
small leaf near the middle, in flower about the length of the leaves, in fruit
20 to 25 em. high; radical leaves numerous, on petioles 3.6 to 10 cm. long, or-
bicular, 2.5 to 4 cm.in diameter, deeply 3-parted, each division again 3- to 5-
parted; the lobes oblong, obtuse, granular-tipped; sepals 5, oblong, obtuse,
deciduous, glabrous; petals 10, glabrous, yellow, oblong, obtuse, tapering at
the base into a slender claw; stamens numerous; carpels very numerous, in &
close head, strongly compressed laterally, 1- to 3-nerved on each side, glabrous,
somewhat utricular; style short, reflexed; ovule 1, erect.

Collected in fruit by Miss Grace E. Cooley, near the top of a snow-covered
ridge, among loose rock, near Juneau, Alaska, August 6, 1891, and collected in
flower by Frederick Funston, near the top of a bare mountain (1,000 meters
high) of the St. Elias Alps, above Disenchantment Bay, Alaska, August 10, 1892.
Mr. Funston says the plant is very rare, and he was able to obtain only five speci-
mens. There is some doubt as to what section of the genus it belongs to, but
probably it should be referred to the Crymodes near R.glacialis. It resembles
very much R. hystriculus of central California, especially in the outline of its
leaves and carpels, but differs particularly in the lobing of the leaves and the
smoothness of the carpels. This new species is named in honor of Miss Grace E.
Cooley, instructor in botany at Wellesley College, who collected the plant on
an excursion to Alaska.

EXPLANATION OF PLATE xXxIl.—1, fruiting specimen collected by Miss Cooley; 2, flower-
ing specimen collected by Mr. Funston, both natural size; a, carpel; b, section of the same,
showing the seed and its attachment; ¢, sepal; d, petal; e, lobe of aleaf from 2. Figuresaand b
are enlarged 7 diameters, ¢ and d 3 diameters, and e 2 diameters.

Sphzralcea orcuttii Rose sp.nov. Perennial(?), 60 to 90 cm. high, with dense,
stellate pubescence throughout; leaves thickish, ovate, entire or somewhat 3-
lobed, with slightly cordate or truncate base, obtuse; flowers small, in close,
glomerate clusters, on short or long racemes; calyx 4 mm. long, with ovate
lobes; petals 8 mm. long, brick-red; styles clavate, thickened; carpels 12, reni-
form, strongly reticulated except the minute terminal portion, 2mm, in diam-
eter, 1-seeded.

Collected near Canso Creek, in the Colorado Desert, California, November 1,
1890, by C. R. Orcutt (No. 2210). This species, although referred to Spheralcea,
can hardly be kept out of Malveopsis. The carpel is more like that of the latter
genus than of any other known species, and yet very similar to those of 8. coul-
teri and S. californica.

Ligusticum macounii Coult. & Rose sp. nov. Plant low, acaulescent, 10 to 12.5
cm. high, glabrous; leaves pinnate, small, 12 to 20 mm. long, on petioles
12 to 30 mm. long; pinne 5, oblong or oval, 3. to 5-lobed or cleft; involucre few-

pedicels of fruit about 2 mm.long; carpels a little compressed dorsally; ribs
prominent, nearly equal; oil tubes 2 or 3 in the intervals, 2 to 4 on the commis-
sural side; fruit broadly ovate, 4 mm. long, purplish; seed face plane.

Common at Cape Vancouver, Alaska, but not seen elsewhere. Collected by
J. M. Macoun, September 8, 1890, for whom it is named. In its low habit it is
very different from all other North American species,

REPORT ON A COLLECTION OF PLANTS MADE IN THE STATES OF
SONORA AND COLIMA, MEXICO, BY DR. EDWARD PALMER, IN THE
YEARS 1890 AND 1891.

By J. N. Rose,

The collection here reported upon was made by Dr, Edward Palmer,
chiefly in the States of Sonora and Colima during the latter part of
1890 and the early months of 1891, The localities visited were Agia-
bampo, Manzanillo, Colima, and Armeria.

Dr. Palmer arrived at Aginbampo September 12, en route for Ala-
mos. Heavy showers had previously fallen and vegetation was well
advanced, but few plants were as yet in flower. From this place he
went directly to Alamos and obtained a valuable collection, upon which
a report has already been made.* While at Alamos one of those dry,
hot winds, so characteristic of this region, occurred and seriously
injuredor killed many of the plants; heavy showers fellagain on Octo-
ber 1, reviving some plants which were in unexposed places. Dr.
Palmer returned to Agiabampo October 3, and was much disappointed
at finding the vegetation in so poor a condition, Collecting was diffi-
eult and unsatisfactory, but his work under these circumstances was
most admirably done, as shown by the many new and interesting plants
enumerated in this report. About 55 species were obtained. The
specimens are numbered from 752 to 815, the result of two weeks’ col-
lecting at this place.

The town of Agiabampo is a small seaport on the Gulf of California,
in the extreme southern part of Sonora. It is 145 miles southeast of
Guaymas and about 60 miles from Alamos, the latter of which is almost
wholly dependent upon Agiabampo for supplies. After finishing the
work at Agiabampo, Dr. Palmer visited Carmen Island and returned
to Guaymas, where the trip to the State of Colima was planned.

Manzanillo was reached by steamer December 1. This village is <
small one, containing only about 500 inhabitants, has an excellent har-
bor, and is situated at the foot of a low range of mountains. It is the
seaport of Colima and is connected with that city by railway. Dr.
Palmer spent the month of December, 1890, about Manzanillo, collecting
chiefly in the mountains and in the low, marshy places about the bay.

He stopped here two weeks in the following year (March 2 to 16, 1891),
securing many plants not obtainable earlier in the season.

From Manzanillo he went to Colima, the capital of the state of the
same name. Almost a month was spent here (January 9 to February
6, 1891), and a second visit was made later, February 27 and 28, One
day (February 15) was spent in Armeria, a small place half way between
Manzanillo and the city of Colima.

The following table will show the places visited, with the dates of col-
lection and the numbers of the plants:

The following interesting account of Colima and Manzanillo is taken
from the consular report for January, 1885, by Emil Mahlo, U. 8. con.
sul at Manzanillo:

The state of Colima lies between 18° 30’ and 19° 28’ north latitude, and 105° to 107°
west longitude; is bounded north by the state of Jalisco, east by the same state and
Michoacan, and south and southwest by the Pacific Ocean. It covers, probably, an
area of 4,000 square miles and is said to have between 70,000 and 75,000 inhabitants.
All these figures are approximations, as no survey of the state has ever been made,
nor have they had an official census since 1871. The city of Colima may have 30,000
inhabitants.

The topographical and geological features of the state are interesting. The ground
rises gradually from the coast, frequently intersected by detached, unconnected
ranges of the Cordilleras (Sierra Madre), forming between them terrace-like, fertile
plains which make Colima one of the richest agricultural states of Mexico,

The city of Colima, in an altitude of 1,450 feet, and 58 miles distant from its port
of Manzanillo, is situated almost in the center of une of the plains, which is proba-
bly 75 miles in circumference, traversed by several rivers and creeks.

Southeast and west of it are wooded mountains from 2,000 to 4,000 feet high, while
to the north the ground again at first rises gradually, whensuddenly, proud and majes-
tic, the double voleano of Colima, about 20 miles distant, pushes itself high up above
the surrounding country into the limits of eternal snow.

From here radiate the almost impassable deep ‘barrancas” which traverse the
state in its northern and northeastern portion, making the communication with the
interior of the Republic exceedingly difficult.

The base of the geological formation is granite; it is in many places overlaid by
feldspathic porphyry, conjointly with limestone, gypsum, and shale. In and near
the barrancas porphyry, trachite, and calcareous conglomerate predominate. The
structure of the voleano of Colima is trachite.

Although entirely within the hot zone, this consular district can truly be said to
present all kinds of climates. F rom the snow of the voleano and the cold climate of

*The numbers between 1410 and 1810 represent Dr. Palmer’s collection in the state
of Sinaloa, made in 1891, The identification of these plants is nearly completed
and will form the basis of a future paper.

the high surrounding country through the temperate, beautiful climate of the ter-
raced slopes and plateaus, down through the semitropical to the tropical heat of the
shores of the Pacific, are represented the three principal climatic zones.

To this difference in the climate is due the great variety of the agricultural prod-
ucts grown in this district. There are only two marked seasons—the rainy and
the dry season, The rains commence invariably at the end of May or the beginning
of June and terminate about the end of October.

I give herewith in a tabular form a résumé of the annual rainfall as observed by
an intelligent private citizen of Colima during the years 1869 to 1880, inclusive.
This is, as far as I know, the first reliable compilation of meteorological observations

ever made on this coast of Mexico. The place of observation is the city of Colima.

Yearly mean for twelve years, 46 inches; yearly average number of rainy days, 79.

It is to be regretted that no hygrometric observations have been made. The atmos-
phere contains considerable humidity the whole year round.

The maximum temperature in the shade, as observed, was, in July, 96° F.; the
minimum in February, 70° F.; greatest variation during the year, 26°; annual
mean, 83°.

On the higher plateau in the interior the thermometer ranges from 54° to 90°.

While the climate of the port of Manzanillo is not very healthy, the city of Colima,
at an elevation of 1,450 feet, and other places farther inland and of a higher alti-
tude, are considered healthy places.

The state of Colima, small though it is, is one of the most fertile of Mexico, and
is noted for the variety of agricultural products. It produces maize, rice, coffee,
sugar, cotton, cocoa, indigo, tobacco, the castor-oil bean, ete. ; and upon the higher
plateaus of Jalisco and’Michoacan wheat, maize, and potatoes are cultivated.

Of all the tropical and semitropical fruits which this part of Mexico produces I
will mention only the following: Cocoa, limes, oranges, mangoes, bananas, pineap-
ples, tamarinds, the chico (a very delicious fruit), the ‘“aguacate,” and the mamey.
Limes are exported from Manzanillo to San Francisco to a considerably extent; also
some pineapples, oranges, and mangoes.

296

In the small state of Colima alone over two hundred different kinds of useful and
valuable woods are encountered; fine cabinet and dyewoods and woods for con-
struction. The most valuable of these, as, for instance, mahogany, cedar, ‘ prima-
vera,” granadillo, ‘ tampinziran” palo-maria, palo-fierro, are articles of export to
Europe and to the United States. They grow in abundance all along the coast and
to aconsiderable distance inland. Among the dyewoods are the “ campeachy,” and
palo Brazil. On the higher plateau fine oak and pine forests are met with. Fibrous
plants and trees also grow in abundance. Besides the majestic ‘palma de coco”
we have the useful palm-nut oil tree (palma de coquito de aceite) and other species
of palms.

The rubber tree grows wild in the forests of the lowland along the Pacific coast.
Some crude rubber is made, chiefly by the natives, and is exported to Europe and to
the United States.

I-am under obligation to many botanists who have aided me in com-
paring my specimens with those owned or controlled by them.

Dr. B. L. Robinson, the present curator of the Harvard Herbarium,
has again and again loaned specimens for comparison and study. He
has also aided me in the study of Ayenia manzanilloana and Crateva
palmeri. Specimens of nearly all the new species have been submitted
to him.

Dr. Casimir DeCandolle, of Geneva, has determined all the plants
of the genus Piper, including one new species and two varieties, as
well as two new species of the genus Trichilia. The following are
the species examined by him:

Mr. J. G. Baker, curator of the Herbarium at Kew, in addition to
suggesting the relationship of the Agave, identified for me Tillandsia
polystachya and T. recurvata,

Mr. W. Botting Hemsley, also of the Kew Gardens, has been espe-
cially helpful in definitely ascertaining that many of my new species
were clearly distinet from closely related ones, specimens of which are
to be found in several cases only at Kew. The following species were
submitted to him for determination or comparison:

Bumelia arborescens. Tpomea nelsont.
Colubrina arborea. Karwinskia parvifolia.

Dr. K. Schumann, of Berlin; Dr. O. Hoffman, of Berlin; Dr. Hans
Schinz, of Zurich; and Dr. A. Engler, of Berlin.

Mr. William M. Canby, Capt. John Donnell Smith, and Mrs. Katha-
rine Brandegee have repeatedly loaned me specimens and aided me in
many ways.

The following plants have been cultivated by Mrs. H. L. T. Woleott
at Halifax, Mass., during the summer and fall of 1892 from seeds
obtained by Dr. Palmer:

Agave angustissima. Ipomea quinquefolia.

It is proper to state here that this work of Mrs. Wolcott has been ot
great assistance to me in supplementing the herbarium specimens
with fresh flowers, fruits, ete. She has entered into this work with
enthusiasm and has looked after the plants almost continually, sub-
jecting herself to no little outlay of time and money.

Capparis cynophallophora L. Sp. Pl. ed. 2.1. 721 (1762). A loose-growing shrub,
10 to 12 feet high. Collected sear the base of the mountains at Manzanillo, Jan-
uary 9 to February 6, 1891. No, 1068.

Capparis palmeri Rose, sp. nov. A compact shrub, 8 feet high: leaves oblong,
acute or obtuse, cordate at base, on very short, puberulent petioles, dull green
on both sides; veins not prominent: petals white, 6 to 8 lines long: stamens
about 60, 15 lines long, about equal to the stipe.—On the mountain sides.
Manzanillo, March 2 to 18, 1891. No. 1858.

Near C. cynophallophora, from which it differs in its more compact habit,
smaller flowers, and leaves not strongly reticulated nor shining, cordate at base.
Both species grow about Manzanillo, ‘This species grows on the mountain sides,
while C. cynophallophora is found in the plain, between the mountain and lagoon.
The favorite habitat of the latter species is along the coast. It was collected
the latter part of January in fruit, while C, palmeri was collected in March in
flower.

Capparis sp. With the above species was sent a branch with immature fruit
which differs in its larger leaves, 3 to 5 inches long, acuminate and cuneate at
base, on petioles sometimes 15 lines long. No. 1858 a,

This plant very much resembles Jaquin’s figure of C. frondosa; see Jacq. Stirp.
Amer. t. 104 (1763). It may not, however, belong to this genus.

Cratzeva palmeri Rose, sp.nov. A diffuse shrub, 8 feet high: leaves 3-foliolate,
on petioles 2 to 4 inches long; leaflets oval to ovate, 2 to 4 inches long, slightly
acuminate, rounded or cuneate at base and more or less oblique, a little rough-
ened above and with crisp hairs beneath: intlorescense coryinbose; flowers
on pedicels 1} to 2 inches long: torus 14 lines long: sepals 4, oblong, 2 lines
long, acute: petals 4, cuneate at base, 3 lines long, not including the long slender
claw (6 to 10 lines long): stamens 16; filaments 2 to 24 inches long: stipe of
ovary 24 to 8 inches long, that of fruit 34 to 4 inches long: fruit pear-shaped,
1jto 2 inches long, obtuse, often slightly appendiculate.—Armeria, February 15,
1891. No, 1285.

This plant seems very distinct from any of the other species, Dr. B. L. Rob-
inson, who has examined it, says: “(It seems to have considerable in common
with C. tapia and C. benthami, but differs from both in its scurfiness, in its smaller
less conspicuous lenticels, its short sublateral inflorescence and longer anthers.”

Crateva sp. <A tree 40 feet high and 40 inches in diameter; fruit the size of a
lime. Manzanillo, December 1 to 31,1891. No. 1013.

Called ‘Zapatillo amarillo.” This tree is taller than either C. gynandra or
C. tapia, the only two species attributed to Mexico. The leaves are more like
the former, but the fruit is larger than in that species.

Morisonia (?)sp. A small tree, 12 feet high, 3 inches in diameter: leaves oblong,
acute, perfoliate near the base, thick, shining and glabrous aboye, stellate-pubes-
cent beneath: fruit spherical, 1} inches in diameter. Manzanillo, December 1
to 31, 1890, No, 1011.

The shape and size of the fruit resembles that of the species of Cratava (No.
1013) collected here also. These specimens do not belong to any described
species, so far as I can learn, and the genus has not been reported previously
from Mexico, It seems to belong in Morisonia, but in the absence of flowers it
is better to refer it doubtfully, as above.

Forchhammeria pallida Liebm. Kjoeb. Vidensk. Meddel. 1853, 94 (1854), A small
tree, 15 to 20 feet high, 5 to 8 inches in diameter, with a large top and a great
profusion of leaves: leaves 24 to 4 inches long, including the petioles (2 to 8 lines
long), 8 to 12 lines broad: calyx of male flowers minute or wanting: 1n flower
while in full leaf. On a sandy beach near Manzanillo, March 2 to 18, 1891. No.
1333, in flower; No. 1348, with immature fruit; No. 1366, with leaves only.

The tree is somewhat taller with the leaves larger than in the type, but in other
respects it agrees with it. Only the male flowers were collected. This is a very
rare plant in herbaria and has not been collected for many years. It was first
seen and described by F, Liebmann, and is now collected the second time,

In habit and flowers the following new species is closely allied:

Fic. 1.—a, Leaf of Forchhammeria palhda showing the lower surface; b, the same as seen from above.

Forchhammeria watsoni Rose, sp. nov. A tree with large spreading top, 15 feet
high, 1 to5 feet in diameter; young branches finely pubescent: leaves coria-
ceous, narrowly to broadly linear, 3 to 5 inches long, 2 to 6 lines broad, more or
less puberulent, cordate at base, strongly reticulated beneath, with prominent
midrib and revolute margins: flowers in slender racemes 2 to 3 inches long:
stamens 18 to 22: fruit pear-shaped, orange-colored, but when fully ripe a
“purplish red,” 5 to 6 lines long.—Common about Guaymas, Mexico, and at low
elevations in the cape region of Lewer California, Collected by Dr, Palmer in

303

1887 (No. 179); February 15, 1890 (No. 167); April 1 and 2, 1890, in flower; and
July 30, 1891, in fruit. Mr, Brandegee reports it from Lower California, and
has recently written me that he obtained it also at Guaymas in 1892,

For illustrations see Frontispiece and PIs, XXtv and XXY.

Considerable doubt has existed among our American botanists as to what this
plant is, owing to the insufficient material which has been collected, This is the
plant referred to under No. 167, on page 90 of this volume. A long note by Dr,
Sereno Watson with reference to the same may be found in Proe, Amer, Acad-
xxiv. 82 (1889), and another by Mr. Brandegee in Proe, Cal. Aead, ser, 2. it. 215
(1889). The ripe fruit is much eaten by birds,

Thave named this remarkable tree in honor of the late Dr. Sereno Watson,
who made a careful study of the plant when it first appeared in the colleetion of
Dr, Palmer in 1887.

In this species, which is clearly distinct from /. pallida, the flowers appear just
after the leaves of the previous growing season have fallen and before the new
leaves are put forth. In Ff. pallida the flowers and leaves appear together: in
both eases the racemes of flowers arise in the axils of the old leaves. FY. pallida
seems to be clearly diwcious as described, while /’. watsonioften has more or less
developed ovaries in the staminate racemes.

Forchhammeria has been variously placed, sometimes in Capparidacew, some-
times in Euphorbiacea, and once in Maleracee, It certainly does not belong to
the latter order nor does it seem to me that it can be placed in Luphorbiacea,
Prof. Radlkofer has made a very careful study of the genus, and believes that 1t
should be retained in Capparidace, where it was first placed by Liebmann,

BIXACEHA.

Cochlospermum hibiscoides Kunth, Syn, Pl. Wy. ii. 214 (1824), A tree 25 to 30
feet high. Common about Mazanillo, December 1 to 31, 1890. No. 1086. This is
a beautiful flowering tree, remaining in bloom for more than two months.

Bixa orellana (?) L. Sp. P1.i.512 (1753). A small tree, 20 feet high, leaves mostly
rounded at base, rarely truneate: fruit broader than long. Along the bay oppo-
site the city of Manzanillo, December | to 31,1890, No. 920.

Xylosma horrida Rose, sp.nov. A tree 30 feet high, 8 mehes in diameter; thorns on
the trunk large, often 3 to 6 inches long, branching: leaves 24 to 34 inches
long, acute or slightly acuminate, lroadly cuneate at base, bluntly serrate,
glabrous and shining: flowers hermaphrodite m short axillary racemes; sepals
small; glandular disk prominent: stamens about 20, much longer than the
sepals: ovary glabrous, prolonged into a slender style; stigmas 2: seeds 2 to 6,
oval in outline.—Manzanillo, March 2 to 18, 1891, No. 1840.

This species agrees with NX. intermedia, collected in Panama, in having its
flowers racemose and hermaphrodite, but this latter plant is described as a
shrub 10 feet high, with large leaves, without thorns, with sepals nearly as long
as the stamens and with 3 stigmas, Its nearest alliance is probably with Y,
calophyllum, I am indebted to Capt. John Donnell Smith for comparing my
specimen with No. 1600 of Spruce, already referred to XV. calophyllum, of which
he writes: “Like your 1340, the spines are long and branched and the herma-
phrodite flowers are racemose and glands of disk numerous, but the leaves are
quite different.”

Xylosma palmeri Rose, sp.nov. Diccio-polygamonus, glabrous, armed at the nodes
with slender straight spines 5 to 15 lines long: leaves about 2 inches long,
elliptical, cuneate at base, alternate, shining, dentate: flowers fasciculately
grouped, 6 to 10 together: pedicels 4 to 5 lines long: male flowers with 4 sepals,
2) to 26 stamens set within the disk, and no style: female or hermaphrodite
flowers, With a prominent disk, few or uo stamens, short style ; broad, peltate

‘Near the base of the mountains about Manzanillo, December 1 to 31, 1890. Nos.
930, 930a, 969, 969a,

This species was collected four different times. All the specimens are so
similar in habit and leaves that I an unable to separate them. Nos. 969 and
69a have all the flowers staminate; in No, 930 they are pistillate or nearly so,
while in 930@ they are hermaphrodite and fertile. No, 930 is said to be a large
shrub, while No. 969 is said to be a small shrub. Dr. Palmer states that the fruit
of No. 930 is red, while that of 930a is tleshy and black. In No. 930a the styles
become cleft to the base in the fruit,

POLYGALACESA.

Krameria palmeri Rose, sp. nov. Compact shrub, 2 to 3 feet high, much branched ;
young branches appressed-pubescent: leaves numerous, alternate, slightly
pubescent, linear, 3 to 9 lines long: pedicels short, bibracteate near the middle:
sepals oblong, obtuse, 3 lines long: petals 5; the2 lower fleshy, broadly obovate,
L line long; the 3upper united below, the middle one ovate, the lateral ones more
dilated, 2 lines long including the claw: stamens4d, slightly shorter than the upper
petals: ovary glabrous: fruit globose, flattened, 4 lines in diameter, glabrous,
yellowish or purplish, covered with stout naked prickles.—Scattered here and
there on the gravelly plains. Agiabampo, October 8 to 15, 1890, No. 753.

This is the same as P. pilosa? Proc, Amer, Aead. xxi. 417, (Palmer’s No,
79 of 1885.)

These plants bear numerous slender tubers similarly to 2, stelliformis, which
differs from this species in the color of the flowers, longer leaves, and «a some-
what different habit. Perhaps it should be referred to 7’. stelliformis asa variety.
Specimens have been cultivated by Mrs. Hl. L. T. Wolcott at Ilalifax, Mass., to
whom I am indebted for some fine blooming plants.

“T think itis pertectly distinct from G. hermannioides H. B. K.; in fact, it comes
nearer to subtriloba H. Bok. We have a specimen of this latter species which
was named by Mr. Triana, and which comes from New Granada, and although
not very like the figure [ think it must be correct. Your minutiflora differs from
this specimen of subtriloba in its smaller leaves, which are acute and not acumi-
nate, rather smaller flowers, and fewer carpels. Of course, compared with the
figure in IL. K.it seems totally different, but in our specimen the flowers are
not always axillary on themain stem, but sometimes ou lateral branches.” E.G.

When I first studied this plant, more than two years ago, I considered it a
new species of MWissadula, and so sent it to Mr. bh. G. Baker, who was then pre-
paring his Synopsis of Malvew. He reported it as the Bastardia hirsutiflora of
Presl. While my plant does not answer to Presl’s description in all respects,
Mr. Baker is doubtless right in considering them the same. One thing, however,
seems certain, and thatis that Presl’s plant belongs with MWissadula rather than
with Bastardia, although Mr, Baker (see Journ, Bot. xxxi. 68) still retains it in
the latter genus.

It differs from astardia in having three styles and carpels instead of tive,
three ovules instead of one in each cell, and the carpels constricted with an
internal projection. Itis like Wissadala, in having the peculiar carpel structure
of that genus, but the carpels are rounded at the apex and only three in number.
The flowers are violet instead of yellow, While these differences may not be
sufticient to establish a generic separation from JVissadula, yet in the light of
other material which T have studied they seem to suggest a good subeenus.

Kither there are several valid species belonging to this group, or IV. hirsuti-
flora is an extremely variable species. One of these forms is Abutilon (WVissadula)
cinctum Branudegee, Zoe, iii. 848 (18938), collected at Las Durasnillas, Sonora, and
with it should probably be referred Palmer's No. 38 (1890) from Alamos. ‘These
specimens have small rounded leaves, merely acute, with short petioles, and the
pubescence is short and dense throughout except some pilose hairs on the calyx.
Another form, and it certainly seems specifically distinct trom that above, is
Mr. Pringle’s No, 4610 (1893) from the state of Jalisco, which he has recently dis-
tributed asa new species of IFissadala, Thestems are covered with pilose hairs,
and the leaves, which are much larger, gradually taper from near the base into
along acumination. Inthe same distribution (No. 4578) is another form, near the
last, but withslehtly different pubescence. Palmer’s Colima plant has thinner,
broader leaves, with a broad, open sinus, and an abrupt acumination. Still
another formis Palmer’s No. 1720 from Yinala, which has not yet been distributed.

Dr. Palmer writes as follows of this plant: ‘The natives call this plant ‘ Tro-
nadora,’ which signifies popping of the leaf. It grows about & feet high, aequir-
ing the greatest perfection upon rich bottom lands. It yields a strong, durable
fiber, which the Zotlahnacar Indians, who live 40 miles southeast of Manzanillo,
utilize in making hammocks, ropes, and carrying-nets, which are so durable that
they last from seven to ten years when in constant use.”

According to Dr. Palmer, the fiber is prepared as follows: ‘ When the plant is
mature, the lateral branches are cut away and the stems are buried in the mud at
the edge of Lake Aleuzagua (Lake of the Devil). Three to four days afterward the
plants are removed and washed, and are then ready for the stripping of the inner
bark or fiber. This is done in the following manner: The workman, standing
upright, with the stem which rests firmly upon the ground in his left hand, presses
the right thumb firmly upon the stick, and taking the fiber between the fingers,
he pulls steadily, bending gradually to the work until he falls upon his knees.
When the fiber is removed the stem rebounds and flies over the shoulder of the
operator, stripped of halfits bark. Thisseemsa very slow process, but jute was
formerly cleaned as slowly, and it was only after many and repeated trials that
machinery was perfected to perform this tedious work, Probably this, like jute,
if allowed to die before cutting, would become brittle, and fit only for paper
manufacture; therefore, in more northern latitudes it may be best to ent the
plants before frost. Experiments will be necessary to ascertain the proper time
for cutting, the length of time it should be immersed, if water will accomplish
the same result as mud, rendering the bark soft and pliable.”

Dr, Palmer says: ‘*The stems, involucre, and capsules are copper-red. The
Mexicans gather the fleshy capsules and use them after drying to make a cool,
refreshing drink. This is an important article of commerce and is sold all over
Mexico,”

I have grown this plant in my grounds, but was not successful in getting it to
flower, The young plants are a bright purple and the leaves are all simple.

1890. No. 1050.

Called “Pochote” or tree cotton. Dr. Palmer says: ‘The flowers are borne
at the extremity of the branches; they are fleshy with a waxy appearance, at
first white, then changing to brown (snuff color) before falling.”

This species seems nearest C. rosea Schum., but is not so tall and has larger,
differently colored flowers. We have followed Dr, K. Schumann in taking up the
name Ceiba in place of Lriodendron.

STERCULIACES.

Physodia corymbosa Pres], Relig. Haenk. ii. 150, t. 72 (1836). About 10 feet high
with a few weak stems leaning for support on adjacent shrubs. Colima, Febru-
ary 27 and 28, 1891. No. i372.

Palmer’s plant from Jalisco (No. 86), 1886, has actuninate sepals and may be
designated variety acuminata var. nov. Dr. K. Schumann refers this genus
to Melochia in Engler & Prantl, Pflanzenf. iii. teil, 6 abt. 80, but it seems
very distinct from our Mexican and North American species of that genus,

Melochia pyramidata L. Syst. ed. 10. ii. 1140 ( 1759). This plaut has several slender
stems from the base: flowers pink. Common in level places at the base of the
mountains. Manzanillo, December 1 to 31,1890. No, 912.

Melochia plicata Presl, Relig. Haenk. ii. 145 (1836). Few stems from the base,
erect, 5 feet high or less: flowers rose-colored. Common on the sides of the
mountains. Manzanillo, December 1 to 31,1890. No. 956,

This seems to be the old species collected by Haenke at Acapulco, which, so far
as I can learn, has not since been found.

Its resemblance to M. tomentosa is striking, but it is easily distinguished by
the fruit.

Waltheria detonsa (Gray, Pl. Wright. ii. 24 (1853). Partly prostrate. A common
plant between the mountains and the lagoon, Manzanillo, December 1 to 31,
1890, No. 1039.

Waltheria americana I. Sp. Pl. ed.2. ii. 941 (1763). A common plant about the
lagoon at the base of the mountains. The Mexicans use a decoction of the
leaves for washing wounds. Manzanillo, December 1 to 31, 1890, No. 961.

Guazuma ulmifolia Lam. Encye. iii. 52 (1789). A medium-sized tree, 25 feet high
and 1 foot indiameter. Manzanillo, December 1 to 31, 1890. No. 960.

It is called “‘Guacima,” and is used in many ways by the Mexicans as a medi-
cine. The fruit is often eaten.

Ayenia manzanilloana Rose, sp. nov. Fruticose: leaves lanceolate, acute, serrate,
10 to 20 lines long, slightly pubescent: flowers 1 to 5 in the axils of the upper
leaves: peduncles (pedicels) 4 to & lines long: sepals ovate, acute: petals with
® small teeth close to the point of union with staminal cup, and with a long
appendage on the back tipped with brown: anthers 3-celled: ovary on a stipe,
1 line long, glabrous except the numerous brown glands.—Very common in the
mountains. Manzanillo, December 1 to 31, 1890. No. 940,

great abundance of fruit. Very common all over the mountains. Manzanillo,
December 1 to 81, 1890, No. 986,

The plant was collected in fruit only, and is tentatively referred here. It isnot
nearly so pubescent as our herbaritm specimens nor as the original description
requires, and fuller material may show it to be a new species.

Dr, Palmer says, ‘Ib resembles a magnolia tree; its large leaves and large
handsome clusters of yellow fruit should recommend it for cultivation in our
Southern States.”

It is nearest 2. palmeri, but has broader and glabrous leaves, and 8- (instead of
10-) glandular calyx, with differently shaped fruit and more compact inflorescence,

It seems to be a good species.

The finding of this rare Texan plant in central Mexico is interesting and it should
be looked for further north. This species had not been collected since the Mexi-
van Boundary Survey was published, until Pringle and Nealley got it in 1890.

RUTACES.

Monnieria trifolia L. Sp. Pl. ed. 2. ii. 986 (1763). In wet places along the bay,
opposite the village. Manzanillo, December 1 to 31, 1891. No. 927.

This genus is not credited to Mexico by Mr. Hemsley in Biol. Centr.-Amer., nor
do IT find it reported anywhere from Mexico, The range of this species is given
as Brazil and Guiana. It is not represented in the National Herbarium, but
through the kindness of Dr. Robinson I have examined the three sheets from
the Gray Herbarium,

My specimens have broader leaflets and the terminal one has anarrow cuneate
base, the peduncles longer, and the two larger sepals broader, and the pellucid
dots are not so conspicuous. Future study may show that this form constitutes
a good variety.

SIMARUBACE4.

Quassia amara L. f. Suppl. Syst. Veg. 235 (1781). Only a single plant seen near
the edge of woods. Manzanillo, March 2 to 18, 1891. No. 13388.

Rigiostachys bracteata Plan, Lond. Journ, Bot. vi. 30 (1847). A small tree, 10
feet high, with trnnk 8 inches in diameter, bearing a large branching top;
leaflets very variable in size and shape: flowers “white” or yellow: petals
oblong, 4 lines long, cuneate at base: ovaries 1 or 2, 2-seeded: seeds collateral:
fruit, a small drupe (?), 8 to 9 lines long: brown, glabrous, with a thin brittle
integument: seed oblong, 6 lines long: cotyledons fleshy, incumbent; albumen
none. Manzanillo, March 2 to 18, 1891. No. 1334,

Bentham and Hooker state that the ovules are frequently solitary. In the
few cases I have examined the ovules were uniformly two, This species has not
before been collected in fruit. Galleotti’sspecimens were only m flower and were
obtained from the coast of Oaxaca about the year 1839. So far as I can learn
this species has not since been collected. The position of the genus is very
uncertain, as the history of it will show.

This genus was described by Planchon in Hooker's Lond, Journ. Bot. vi. 29
(1847). He places it next to Suriana (Simarubacea) and considers it a connecting
link between the orders Connaracer and Ochnacer, Me states that it has the
leaves of a Sapindus (Sapindacew), the aspect of a Gomphia, and the structure
of Suriana,

Walper in his Annales Bot. Syst. i, 202 (1848) refers the genus to Connaracee,
and Bentham Hooker in Gen. Plant. i. 809 (1862) place it in Simarubacew, but
speak of its doubtful affinities and suggest its probable reference to Dosacea.
Baillon in Adinsonia x. 42 (1871) is also inclined to refer it to this latter order.
Hemsley in Biol, Centr.-Amer. i. 178, retains it in Simarubacee.

Baillon also refers to the genus in Hist. des Pl. iv. 408 (translation iv. 415) and
Dict. Bot. iii. 738.

RHAMNACES,

Zizyphus mexicana hose, sp. nov. A tree 25 feet high, 9 inches in diameter, with
large, dense top; spines straight and scattered; leaves oblong, 2 to 3 inches
long, strongly 3-nerved, coriaceous, glabrous, obtuse or retuse, cuneate or
rounded at base, crenately toothed; petioles 8 to 8 lines lone: peduncle 6 lines
long; flowers 8 to 10 in a small umbel; peduncle and pedicels (as well as young
leaves and branches) a little pubescent: calyx nearly glabrous, 5-parted: petals
5, small: stamens 5: friit drupaceous, 6 to 8 lines in diameter.—On hills about
Armeria, February 27 and 28. No. 1278.

This species seems pearest Z qualemalensis, but it is a small tree, with leaves
commonly cuneate at base, and longer petioles and peduncles, Mr. Hemsley writes
me that the species 1s quite distinct. Phe fruits are gathered by the Mexicans
and sold in the markets by the dozen, They are used in the place of soap and
are lighly prized for washing woolen goods. They are called “ Amole,”

Karwinskia parvifolia Kose,sp.uov. Large bush, 5 to 10 feet high, glabrous through-
out: leaves opposite or subopposite, small, oblong, or linear-oblong, about 1
inch long on short petioles, obtuse, rounded, or somewhat tapering at base, the
inargin somewhat black-dotted; stipule minute: pedicels short; peduncles short
or none: stigma 2-lobed: fruit mostly single, axillary, black, 2-celled.—Agia-
bampo, October 3 to 15, 1890. No. 773.

For illustration see Pl, XXx1.

This plant is not in flower, but it has all the indications of being a Karwins-
kia. It differs from WW. humboldtiana in its much smaller leaves, the fruit more
tapering at base, its larger disk, ete,

Mr. Hemsley writes me that it is not Coulter's (No.3) from Sonora, nor is it
represented in the Herbarium at Kew.

Colubrina arborea (?) Brandegee, Zot, iv. 401 (1894). Along the edee of thick
woods. Armeria, February 15, 1891. No, 1298.

Dr. Palmer says this tree has the habit of the weeping willows. Its long
hanging branches are loaded with fruit. I have referred this plant as above
with some doubt. Lat first deseribed it as a new species, but since then Mr.
Brandegee has described a species from Lower California under the above name,
to which my plant probably belongs.

Although I have not seen this species, yet this plant is probably rightly
referred. Most of the upper leaflets are small (one-half inch long) as described,
yet they are often 1) inches long. Dr. Palmer writes of it as follows: ‘One of
the most attractive of plants. It is upright and with a compact symmetrical
top. It is a free bloomer and the flowers are a beautiful yellow with brown
patches, and it is worthy of cultivation.’

In 1891 I sent seed to Kew where it was planted and proves to be a most prom-
ising plant. Sir Joseph Hooker has recently figured and redescribed it in Curtis’s
Botanienl Magazine (vol. xlix. pl. 7306).

The following note is taken from the above article:

“A very handsome greenhouse plant described as sufirnticose, but, though
copiously branched, harbaceous as grown in the Royal Gardens, where it forms
a conspicuous winter feature in the Begonia house, flowering freely from Decem-
ber to March and attaining a yard in height. It was discovered by the late Dr.
Sinclair, surgeon in H. M. Blossom, during the surveying voyage of Capt. Beechey,
at Acapulco on the west coast of Mexico, and also in the province of Jalisco by
other officers of the ship, and on the Volcano de Fuego in Guatemala, altitude
5,300 feet, by Mr. Salvin, PF. R.S., and at Mazatenango, by Bernoulli.”

The Garden, in its issue of March 25, 1893, contains the following note respect-
ing this plant:

“Crotalaria longirostrata may be seen in bloom in the stove at Kew, It is a
thoroughly useful plant for flowering in the winter months, and the specimen
there has kept up a gay display for over two months, notwithstanding the fogs,
which are peculiarly trying to stove subjects, This species is still in full bloom,
bearing at the ends of the long slender shoots clusters of large, bright yellow
pea-shaped flowers, which make a great show of color in the winter season. It
is easily propagated by cuttings, and all who wish for something distinct and
attractive in their stoves during the so-called dark months of the year, should
make good note of it.”

An upright shrub with many lateral branches: leaflets 25 to 40 pairs, often
t to 5 lines long; stipules ovate-acuminate, early deciduous: the bractlets
subtending the flowers small, 4 line long, oval, 5-nerved: calyx 1 line long ;*
teeth 5, small, the lower a little narrower and longer; staminal tube cleft above

This species was doubtfuliy referred to Brya
by Dr. Watson in the Proc. Amer, Acad. xxii.

was drawn was onlyin flower, although speei-
mens in the National Herbarium of the same
distribution (Palmer’s 1886) have nearly ma-
ture leguines. In the above description I have

the original, This species seems to belong very
clearly to -Eschynomene vather than to Brya. Dr. B.L, Robinson has independ-
ently reached the same conclusion, .lschynomene differs from the latter in liav-
ing the staminal tube cleft below as well as above, the bractlets appressed to
the calyx, leaflets more numerous and appendiculate, stipules not spinescent,
and joints often more than 2. [In all the above points my specimens agree with
Aschynomene. Brya also has large yellow flowers. Two of the three species of
Brya have single leaflets and in 4. eberus the leaflets are evergreen.

This tree has a iarge spreading top; its numerous clusters of flowers are very
attractive.

This species seems nearest L. sericens, but differs in its larger obtuse and
strongly veined leaves, longer raceme and larger flowers.

Lonchocarpus (?) sp. A small tree, 15 feet high, 8 inches in diameter, with large
spreading top: leaflets 9 to 13, oblong or oval, 1 to 2 inches long, obtuse, gla-
brous and shining above, rusty-pubescent beneath, with veins impressed

base of the mountains. Manzanillo, December 1 to 31, 1890. No. 984.

The seeds are sometimes eaten by birds, but with poisonous effects.

This species certainly comes near L, rugosus and answers Bentham’s descrip-
tion very well except in the pods. In the absence of flowers, therefore, I have
referred it without specific name.

Lonchocarpus sp. A diffuse shrub, 6 to & feet high: leaves small, alternate, with
5 to 7 leaflets; leaflets opposite, oval, obtuse or retuse, thin, 6 to 15 lines long,

cup-shaped, truncate, brownish-pubescent, L line long: coroHa purplish; ban-
ner broader than long, 4 lines long, 5 lines broad, retuse: style glabrous; ovary
pubescent: legume not seen. In rocky places near the base of the mountains.

This plant is called “Palo alejo.” The bark is used by fishermen, who crush
it and throw it into the water to stun fish,

Apparently very common on mountain sides both at Colima and Manzanillo.
Its published range is now extended much farther northward, According to Mr.
Hemsley 1t has been collected three or four times before, but not north of the
Central American States.

Mr. Bentham did not have mature legumes for his description, and hence I
have carefully characterized them «bove, as well as filled in some dimensions

This species is very different from our other Mexican specimens in its oblique
leaflets and glandular stamens.

Cesalpinia (Coulteria) platyloba Watson, Proc. Amer, Acad. xxi. 425 (1886). A
shrub, 8 feet high, glabrous: leaves twice pinnate; pinnie 2 to 4 pairs; leatlets
6 to 9 pairs, oblong, acute, 1 to 2 inches long, glabrous: racemes axillary, 3 to 4
inches long: lower sepal pectinate-fimbriate: petals yellow: stamens hairy at
base, about the length of the petals: pods indehiscent, glabrous, 3 to 6 inches
long, 10 to 15 lines broad, Along the sandy beach a few feet above tide water.

Thisseems to be the plant that Dr. Watson referred as above while questioning
its generic position. My plant differs in several minor details, and especially
in the length of the pods. Flowering specimens are now for the first time col-
lected and show clearly that the plant belongs to this genus and to the seetion
Coulteria. The specimens ought to be compared with the South American spe-
cies C. finctoria, to which it is certainly closely related. Here, perhaps, may he
referred Coulter's No, 873 from Zimipan, cited by Mr. Hemsley in Biol. Cent.-

stamens 10, woolly at base, a little longer than the corolla: legume faleate, nar-
rowed downward, 2 inches long, densely covered with stipitate glands, 3- to
d-seeded: seed 4 lines broad. Manzanillo, March 2 to 18, 1891. No. 1397.

This species resembles C, palmeri in its leguines, but in foliage approaches
C. mericana.

Dr. Palmer also collected a form closely related to this from Colima, but with
larger, straight pods, less tapering at base, leaflets smaller and often 4 pairs,

Fig. 6.—Leueena macrocarpa; a, the terminal pair of leaflets; b, a section of the legume.

This is a rare species and has been poorly understood in this country. This
confusion has been due to two factors: First, the absence of the species from all
our collections, and, second, because Mr. Bentham referred to it (Trans. Linn,
Soc, xxx.) an undescribed species, which proves to be a species of Albizzia. I
should state here that it is through the kindness of Mr. Hemsley, of Kew, that
T have been able to clearly fix upon this as the true ZL. macrophylla.

The pods described above were detached, and while a little Jonger than the
type seem to be the same. They may, however, as suggested by Mr. Hemsley,
belong to a different species.

to 3 inches long, oblong or oval, somewhat oblique, acute, rounded at base,
strongly reticulated, a little puberulent beneath: flowers in small, compact
heads in terminal naked racemes: legume large, 8 to 10 inches long, L to 14 inches
broad; stipes 9 to 12 lines long. This is 1. macrophylla, Watson Proc. Amer,
Acad. xxii. 409, collected by Palmer at Rio Blanco, Stateof Jalisco, August L886
(No, 320), The flowering specimens of No. 320 are made the type of this species.
Here undoubtedly belongs Pringle’s No. 3848, from the same State, collected in
1891 and distributed under L. macrophylla, but the name is corrected in Mr.
Pringle’s list for 1892. Palmer’s No. 981 from Manzanillo (December 1 to 31, 1891)
is also referred here, but with less confidence. The specimens are only in fruit
and the foliage and legumes are so similar to Mr. Brandegee’s .1]bizzia occidentalis
that without flowers it is next to impossible to separate the two. Palmer’s Jalisco
plant, which is undoubtedly a true Leucana, has pods exactly like those from
Manzanillo.

Mr. Hemsley has compared these specimens with the type at Kew and decided
that it is not the L. macrophylla of Bentham. The leaves are in faet much
larger than in that species.

Acacia cochliacantha Humb. & Bonp. in Willd. Sp. Pl. iv. LO8SL (1805), Some-

flowers sweet-scented: legume with thin valves covered with a close tomentum.
Along river bottoms and mountain sides, Colima, January 9 to February 6, 1891.
No. 1209.

l have seen flowering specimens only of 4. coulteri, with which the above com-
pares fairly well. Bentham’s description, however, calls for fewer pinme,
shorter stipes, and glabrous pods.

I have not been able to compare this with authentically named specimens, but
it answers fairly well for the above species. The leaves are very similar to C.
Jacquini Griesb (7), but this species is said to be climbing.

This species is not reported in Biol. Cent.-Amer., but it was obtained by
Palmer at Guaymas, 1887 (Watson in Proc, Amer. Acad. xxix. 49), and by W. G.
Wright, at Mazatlan, in 1889. We also have specimens collected in Florida and

Casearia corymbosa H. B. K. Nov. Gen. et Spec. v. 366 (1821). Colima, February
27 and 28,1891. No, 1317.

Dr. Palmer says, “the plant is loaded with white flowers and with new leaves

and shoots, which are very full of moisture, making them very difficult to dry.”

“Combretum reticulatum, which is an Abyssinian species, is credited to Mexico by

Walper (Repert. ii. 65), and this is followed by Mr. Hemsley (Biol. Cent.-Amer. i.
404), while C. tetragonum Pres], was evidently intended.

This species may not be properly referred, but it is certainly near Dr. Palmer’s
Jalisco plant named C. corymbosa by Dr. Watson. The stamens in my flower

T have not been able to place this in any described species, and, owing to the
present confusion in the genus, I have deemed it best not to give if a spectic
name.

This is the same as Palmer’s No. 416 from Jalisco, referred as above by Dr.
Gray.

In the same collection (No. 462) is a specimen which Dr. Gray referred to C.
calocephala DC. This was also collected by Pringle in 1890 (No. 3256) from near
the same locality. Both the latter specimens seem to differ from specimens dis-
tributed by Capt. John Donnell Smith under the name C. calocephata, Mr.
Smith’s specimens have larger and more strongly veined leaves, and larger
calyx (3 lines long) and corolla (4 to 5 lines long), the latter blue: Palmer’s and
Pringle’s Jalisco specimens have the calyx 14 to 2 lines long, the corolla with very
slender tube, 2 to 3 lines long, and purple or rose-colored,

lam inclined to think that Mr. Smith’s specimens are the true ©, calocephata,
while the latter belongs to an undescribed species.

Spermacoce sp. Low herb, much branched, and more or less spreading, rough on
the angles: leaves linear or narrowly lanceolate: flowers white in dense glomer-
ules, 1 terminal and 2 or 8 lateral: calyx teeth 2: corolla 4-parted: stamens
4: fruit pubescent above. On sandy spots about the lagoon. Manzanillo, De-
cember 1 to 31, 1890. No. 974.

This species is near 8. podocephala, but differs in being an annual, in the char-
acter of the leaves, etc.

This plant has not only the corolla of Hofmeisteria, as stated by Bentham and
Hooker in Gen. Plant., butthe whole habit, the foliage, the single heads on long

naked peduncles, etc. Technically it is not a Hofmeisteria, because it lacks the
outer row of pappus, but its relationships are certainly there.

Manzanillo, December 1 to 31, 1890. No. 898.

The finding of this plant by Dr. Palmer brings to light an old but little-
known species. It is probably not in any American herbarium, nor have they
itat Kew, It has only twice before been collected, first by Thaddaeus Haenke,
in the latter part of the last century—about 1790 or 1792. It was probably
obtained on his trip with Luis Née from Acapulco to the City of Mexico, It was
next collected by Karwinski, about Acapulco, probably between 1826 and 1831.

is put up in small packages and sold in the markets of the city.” It is the same
plant as Palmer’s No, 268 (1885) from Jalisco, which Dr. Gray refers to H. lepto-
glossa DC.in Proc. Amer, Acad, xxii, 421,regarding it as only aform of H. lamarckii.
It seems to me to be.a form of H. inuloides, Palmer’s specimens differ from H.

The range of this species as given by Mr. Hemsley in Biol. Cont.-Amer. is along
the Atlantic coast of South Mexico and South America, [cannot learn that it
has before been found on the west coast of Mexico. My specimens agree with

(reprint, 20) and Eng. & Prantl, Pflanzenf. iv. abt. 5, 390 (1894). A new genusof
Helianthoidew. Heads heterogamous, radiate, few-flowered ; ray-flowers sterile,
in 1 row; disk-flowers hermaphrodite, fertile. Involucre oblong; bracts in 4
series, broad and obtuse; receptacle very small, almost flat; corolla of ray-
flowers without style, spreading, 2-lobed or merely notched: corolla of disk-
flowers regular, 5-toothed; proper tube short; throat tubular: stamens entire
at base; style-branches short, somewhat flattened, with an ovate, acute tip:
akenes a little flattened, cuneate-oblong: pappus none.—Shrubby, much
branched: leaves opposite, slender and entire: heads in small compact cymes
terminating the branches. ,

For illustration see Pl, XXXII,

This genus seems to belong to Bentham and Hooker's third section of Verbe-
sinew and near Varilla, although it differs from it quite widely.

Mr. Canby in a letter to me points out the close resemblance in habit of this
species to Gymnosperma, but of course its opposite leaves and bracts on the
receptacle keep it distinct from this genus.

Dr. 0. Hoffmann, of Berlin, has placed the genus next to Gymnolomia, from
which it differs in its cylindrical involucre and very unequal bracts.

Agiabampoa congesta Rose, ll. ce. A loose-growing shrub, 4 to 5 feet high, quite
woody below with several stems from the base, glabrous or with some hispid
pubescence: leaves (uppermost ones often alternate) linear to linear-lanceolate,
3-nerved, a little hispid on both sides, 2 to 6 inches long: heads (sessile or on
short pedicels) 3 lines long: involucral bracts 3- to 5-nerved, coriaceous with
green tips, oblong and obtuse and with long, oily glands on the back: rays 5,
yellow, oval to oval-oblong, 14 to 2 lines long: disk-corolla 2 lines or less long
with a very short proper tube: akenes black, glabrous, 1} lines long.—Common
in rocky creek bottoms, Agiabampo, October 3 to 15, 1891. No. 752.

The bracts are more or less viscid as seems also to be the case with Varilla.

These two forms have been referred to this polymorphous species, although
they differ considerably from each other.

Encelia (Simsia) purpurea Rose, sp. nov, Stems 2 to 3 feet high, with spreading
branches; younger parts villose-pubescent: leaves ovate, 6 to 18 lines long, acute,
truncate or a little cuneate at base, entire or somewhat serrate, appressed-
pubescent on both sides, short-petioled: inflorescence somewhat corymbose;
peduncles 6 to 18 lines long: heads slender, eylindri sal, 3 to 5 lines long; bracts
of two lengths, ovate-lanceolate, acute, somewhat hispid, 3- to 5-nerved, more or
less purplish: involucral bracts emarginate or short-appendiculate, purplish:
‘ays 5 to 8, 2 to 3 lines long, a little exserted beyond the disk, sterile, slightly
2-toothed, yellow: disk-corolla 2} lines long, with avery short proper tube (one-
fourth line long), a slender cylindrical throat and 5 small teeth: akenes strongly
flattened, 24 lines long, appressed, pubescent: pappus of 2 nearly equal awns
a little longer than the akenes.—Only two plants found, these in a creek
bottom. Colima, January 9 to February 6, 1891. No. 1105. A peculiar species,
resembling £. eraristata in the color and shape of the involucral bracts, but of
different habit.

Verbesina spherocephala Gray in Watson, Proc. Amer, Acad. xxii. 428 (1887).
Leavestoothed. Bought in the market at Colima, January 9 to February 6, 1891,
No, 1404.

Spilanthes alba Willd. Sp. PI. iii. pt. 3. 1714 (1803), Involucral bracts about8: rays
none: corolla 4-toothed: outer akenes 3-angled; inner ones flat: receptacle high-
conical. Grassy plains and river bottoms. Colima, January 9 to February 6,
1891. No. 1192.

This is the S. alba of Hemsley’s Biol. Cent.-Amer., but differs from the deserip-
tion in the number and shape of the involucral bracts. Fendler’s No. 166 from
the Isthmus of Panama seems to be the same species, 8, pseudo-acmella var, of
Capt. Wilkes’ Exped. (probably from the East Indies) seems very near our
plant.

Cosmos sulfureus Cav. Ic. i. 56, t. 79 (1791). About 4 feet high, with a rough
pubescence: leaves bi- to tri-pinnatifid, often 12 inches or more long, with rachis
and midrib hispid; ultimate pinna, entire or 2- to 3-toothed: peduncles 7 to
10 inches long: bracts of outer involucre 2 lines long, ovate-linear, 3-nerved ;
inner involucre, twice longer, scarions: rays 6 to 8, oblong; 6 to 9 lines long,
3-toothed, “amber” or deep orange: akenes 8 to 9 lines long, including the long
beak, upwardly scabrous and with 2 spreading awns. Not common, and at the
time of collection almost past blooming. Colima, January 9 to February 6, 1891.
No. 1222.

This species is the same as the one collected by Palmer in Jalisco (1886) and
referred as above by Dr. Gray.

I have not seen other specimens of this species, nor have [ seen Cavanilles’

337

plate of the same. The style tips are peculiar for the genus, being long and
filiform.

I have grown this species in my grounds from seed. It is a rank, weedy look-
ing plant, with rather coarse foliage. Some of the larger specimens reach the
height of 7 feet. None of the plants bloomed out of doors, but they had budded
when killed by frost the Ist of November. A small specimen was saved and
transplanted to the greenhouse and flowered about the middle of December.
The flowevs are very attractive and are fully 2 inches in diameter. The chief
objection to the plant is its very late blooming, being several weeks later than
the commonly cultivated species. The flowering continues for several months.

Colima, January 9 to February 6, 1891. No. 1215,

Tridax dubia Rose, sp. pov. A slender and more or less procumbent herb, somewhat
hirsute: leaves opposite, ovate to lanceolate, serrate: inflorescence afew-flowered
corymb; pedicels variable in length, sometimes 2 to 3 inches long: involucral
bracts 5, distinct, herbaceous, ovate, acute: rays yellow, 5, fertile, 3-toothed;
disk flowers perfect, fertile: pappus of 10 oblong, obtuse, ciliate-pectinate
pale: akenes slightly flattened dorsally, a little pilose.—Along the river bot-
tom; not common. Colima, January 9 to February 6, 1891. No. 1173.

For illustration see Pl. xxxt,

This species is doubtfully referred to Tridax, from which it differs in its less
simple inflorescence, involucral bracts in a single series, and fertile rays, and in
the character of the pappus.

Mr. Win, M. Canby, who has been very much interested in the plants, writes
me as follows: ‘The plant clearly belongs where you place it, viz, in subtribe
Galinsogea, of tribe Helianthoidew. Bentham and Hooker give but 7 genera
in this subtribe and this plant is nearly related to but two of these, Galinsoga and
Tridax, and does not fully agree with either. On the whole, however, it seems
to me to be sufficiently near Tridax to be taken into it. In the detailed generic
description of Bentham and Hooker is the phrase concerning the pappus of
‘aristato-acuminatiw.’ If this were left out you would not have much difficulty
in bringing your plant into it. Now, in Tridaz trilobata (which has been pnt under
Galinsoga by good botanists) you have a pappus which is really nearer that of
your plant than of other species of Tridar, Bentham and Hooker suppress, I
think, with reason, all the genera which have been found to accommodate spe-
cies not just Tridax or Galinsoga and unite them with the former. Your plant
is much like the original species of Tridax (T. procumbens) in the receptacle,
chaff, and scales of the involucre, It approaches T. trilobata in the pappus,
It seems to me that the simple fact of its having a definite number of pappi
which are only ciliate-pectinate instead of plumose-ciliate and which are not
aristate should not take it out of a genus in which there is as much variation
in species as in Tridax.”

Tridax procumbens L. Sp. Pl. ii. 900 (1753), Colima, January 9 to February 6,
1891. No. 1183.

Plaveria robusta Rose, sp. nov. About 4 feet high, pubescent or glabrate below:
leaves lanceolate or linear above, 3 to 5 inches long, acute to acuminate, taper-
ing into a slender petiole, 3-nerved, entire or slightly serrate: inflorescence open,
corymbose ; heads small, with 3 involucral bracts: flowers 3; ray 1, obicular,

338

about 1 line long; disk flowers 2: akenes § of a line long.—Colima, February 27
and 28, 1891. No. 1299. Also collected by Marcus E. Jones, June 28, 1892, near
Armeria. No. 276.

This species is near F’, linearis and F, longifolia, but with different leaves, fewer
flowers, etc.

Porophyllum palmeri Rose, sp. nov. Perennial, much branched and open, several
feet high, reddish and glabrous throughout: leaves opposite, oblong to broadly
linear, 9 to 20 lines long, mostly obtuse, with linear glands along the margin:
flowers abundant, in numerous small corymbs: involucral bracts 5, 6 lines long,
linear, acute, greenish or with purplish margin, with black glands: corolla tube
very slender with 5 equal slender lobes: akenes linear, 34 lines long: pappus
abundant, shorter than the corolla.—Collected in a ravine bottom, in the shade
of bushes. Colima, January 9 to February 6, 1891. No. 1142.

For illustration see Pl. XXXIV.

This plant seems nearest P. jorullensé, but differs in its inflorescence, gland-
bearing leaves which are not reticulated, its pappus which is shorter than the
corolla, etc.

Dysodia tagetiflora Lag. Gen. et Spec. Nov. 29 (1816). Very common on grassy plains
about Colima, January 9 to February 6, 1891. No. 1157.

Tagetes subulata Llav. & Lex. Nov. Veg. Desc. fase. 1. 31 (1824). Collected on the
river bank; also bought in the market under the name * Santa Maria.” It has
a very strong, disagreeable odor, and is manufactured into an insect powder.

Tagetes tenuifolia Cav. Ic. ii. 54, t. 169 (1793). Common in river bottoms at Colima,
February 27 and 28, 1891. No. 1318.

Pectis arenaria Benth. Bot. Voy. Sulph. 110 (1844). Leaves 1 to 2 inches long:
akenes 4 lines long. The plant grows in the sand just above high tide at Man-
zanillo. December 1 to 31, 1890. No. 971.

Pectis coulteri Harvey & Gray, Pl. Fendl. 62 (1849). Very common on sandy
plains. Agiabampo, October 3 to 15, 1890. No. 759.

Pectis diffusa Hook. & Arn. Bot. Beech. Voy. 296 (1840). Common by river banks
at Colima, January 9 to February 6, 1891. No, 1155.

This seems to be Hooker and Arnott’s species. The pappus, which is described
as of 10 to 29 setiv, is quite variable. These plants have many akeues with 10 to
14 set, but often there are only 3 to 5.

It is the same as Palmer’s No. 4 (1886) and Pringle’s No. 1814 from Jalisco, both
doubtfully referred to the above species.

Pectis palmeri Watson, Proc. Amer. Acad. xxiv. 58 (1889). Very common on rich
bottoms near creek. Agiabampo, October 3 to 15, 1890. No. 765.

Pectis prostrata Cav. Ic. iv. 12, t. 324 (1797). Not common. Found near the

Dr. Palmer says this plant seems to have some good medical properties and is
much used by the medicine venders under the name of “ Maguapas.”

Cacalia pringlei Watson, Proc. Amer. Acad. xxv. 156 (1890). Stems 6 feet high:
flowers white. Collected on the grassy slope of a hill. Colima, January 9 to

Near the hase of the mountains. Manzanillo, December 1 to 31, 1890. No. 897.

This plant, which is now collected for the second time, was obtained by Sesse

339

and Mocino over a hundred years ago (about 1788), but the station is not men-
tioned; and it is more than sixty years since Don first published (1833) his
description.

Mr, Hemsley writes me that the type is probably in the Delessent Herbarium
at Geneva, and that the species was not represented in the Kew Herbarium.

Lucuma sp. Asmall shrub, 10 feet high; young branches pubescent: leaves oblan-
ceolate, tapering into aslender petiole (1 inch or more long), glabrous, obtuse
or acutish, shining above; 5 to 8 inches long, 14 to 24 inches broad: flowers in
clusters of 2 to 4, supra-axillary: peduncles 6 to 7 lines long, pubescent: sepals
5, orbicular, obtuse, imbricated, pubescent without, subequal, 3 lines long: corolla
dull white, somewhat tubular, 6 lines long, 5-cleft to the middle or into obtuse
lobes, puberulent: stamens and staminodia equally inserted near the top of the
tube; stamens included on short filaments about equal to the anthers; stamin-
odia linear, longer than the stamens; ovary pubescent, 5-celled: fruit unknown.
Manzanillo, March 2 to 18, 1891, No. 1346.

Very similar to a specimen in the National Herbarium from a plant culti-
vated in Florida under the name L. fruticosa.

SAPOTACES.

Bumelia arborescens Rose, sp. nov. <A tree with a wide-spreading top; trunk 1
foot in diameter; branches often bearing short, straight thorns: leaves when
young clothed with a close, short, reddish pubescence, in age glabrous and shin-
ing, oblong, obtuse, 2 to 3 inches long: flowers very numerous in the axils of the
leaves: pedicels 14 to 24 lines long: scalyx and pedicels ferruginous-pubescent:
fruit glabrous. Colima, January 9 to February 6,1891. No. 1123.

Mr. Hemsley writes that they have not this species in the herbarium at Kew.

Perhaps nearest B. persimilis.
APOCYNACEZ..

Thevetia cuneifolia (H. B. K.) A. DC. Prod. viii. 344 (1844); Cerberia cuneifolia H. B.
K. Nov. Gen. et Spec. iii. 224 (1818). A shrub 20 feet high, 6 to 12 inches in diam-
eter, leaves often 5 to 6 inches long: flowers yellow. Manzanillo, December 1 to
31, 1890. No. 1069,

This shrub gives out an abundance of milky juice when cut. The plant has
apparently only been collected twice, first by Humboldt in flower and next by

340

Dr. Palmer, in 1886, in fruit.

At Manzanillo the plant was both in flower and
fruit. It differs but slightly from the description in H.B.K., Nova Genera et
Species Plantarum vol. iii, The leaves are, however, a little longer.

This plant is said to climb to the top of the tallest trees. If a Macroscepis it
is a new species, but as it is only in fruit it is referred to as above. Bourgeau’s

dark corolla is very pleasing.

An interesting note regarding the
culture of this species occurs in the
Gardener’s Chronicle (April 15, 1893).
It is there spoken of as a very at-
tractive plant and worthy of a place
in our gardens,

Asclepias glaucescens H. B. K. Nov.
Gen. et Spee, iil. 190, t. 227 (1818).
Leaves 5 to 6 inches long, acute.
Colima, January 9 to February 6, Fic. 8.—a, Hood from Asclepias glaucescens; b, the
1891. No. 1150. same, showing the horn; c, hood from A. elata; d,

the same, showing the horn. All enlarged four
, times.

A comparison of these specimens
with those referred to A. glaucescens
from the United States shows that the latter belong to a different though closely
allied species.

A, glaucescens was described and figured by H. B. K. in Nov. Gen. et Spee. iii., p.
190, t. 227, from plants collected between Acapulco and La Verta de la Moxonera,
The following note is from the Bot. Gaz. xvii. 193.

Dr. Gray in Syn. F1., ii. 92. refers the 4. sullivantii Torrey, Bot. Mex. Bound,
p. 162, to this species. The United States species, however, is clearly distinct from
A, glaucescens, aud should be referred to A. elata Benth. Dr. Gray, indeed, in
the Syn. Flora, Suppl. p. 407, considers the two to be the same species; but in the
light of this new material Iam convinced we have two good species, although
closely related.

A. elata Benth. has oblong or oval leaves, rounded at the apex, very similar to
those of 4. obtusifolia.

A. glaucescens has much longer and narrower leaves, oblong to linear-oblong
and acute: the flowers are much larger in 4. elata, and the hoods are spreading,
exposing the gynostegium; in 4. glaucescens the hoods are longer instead of
shorter than the gynostegium, and erect and connivent. There is also a good

342

character in the horns. Dr. Gray clearly describes the form as it is in 4, elata
(under 1. glaucescens Syn. F1.), where, in speaking of the hood, he says ‘the
whole length within oceupied by a broad and thin crest, which is 2-lobed at the
suminit, the outer lobe broad and rounded, the inner a short triangular-subulate
nearly included horn;” in A. glawcescens the horn is a broad, triangular, incurved,
entire beak.

BORAGINACES.

Cordia sp. A tree 25 feet high, about 10 inches in diameter, younger stems whitish:
leaves broadly lanceolate to broadly ovate, acute to somewhat acuminate, with
truneate or somewhat cuneate base, green and smooth above, whitish and with
a short, close pubescence below: flowers very abundant in large open panicles:
pedicels short, mostly 1 line long, sometimes 4 lines long: flower-buds globular,
opening by a deciduous operculum: calyx short-campanulate, 2 to 3 lines long,
whitish pubescent, somewhat 10-ribbed, with small teeth: corolla with short
tube scarcely longer than the calyx, limb spreading (10 to 12 lines broad)
deeply cut into 5 oblong, obtuse lobes, white (?), marcescent: stamens 5, exserted :
style twice 2-parted: drupe ovate-acuminate, 4-celled, A very common tree
about Manzanillo and worthy of cultivation. December 1 to 31, 1890. No. 895,

The marcescent corolla seems to ally this species with De Candolle’s section
Gerascanthus. Of all the specimens of Cordia which we have seen, it most resem-
bles C. (Varronia) alba,

This plant almost completely covers the bushes and shrubs over which it runs.
Dr. Palmer speaks of a large shrub 15 feet high, with considerable spread of
branches, which was entirely hidden by it. I do not find that this plant is
reported from Mexico, but it seems to be common there, and as it corresponds
fairly well with the description and with a single specimen from Brazil, I have
no hesitancy in referring it as above.

Tournefortia hirsutissima (?) L. Sp. Pl. ed. 2. i, 201 (1762). Tall shrubby
climber covering the tops of the highest trees with its numerous branches: the
small drupes at first dull white and fleshy: in age hard and dry. Manzanillo,
December 1 to 31, 1890. No. 1043.

This plant seems to be the same as the one obtained by C. Wright in Nicaragua,
aud also referred as above. In both of these specimens the leaves are nearly
glabrous in age. In De Candolle’s Prodromus this species is described as “ fruti-
cosa erecta.” Also about Colima, January 9 to February 6, 1891. No. 1242.

CONVOLVULACES.

Ipomcea (Orthipomcea) wolcottiana Rose, Garden and Forest, vii. 367 (1894). A
tree, 30 feet high, sometimes 1 foot in diameter: branches slender, somewhat,
drooping: leaves ovate to ovate-lanceolate, 3 to5 inches long, 14 to 34 inches
broad, rounded or truncate at base, acuminate, glabrous, on petioles 2 to 4
inches long: flowers in numerous short racemes or corymbs mostly naked:
pedicels jointed near the base, little if at all thickened upward, 4 to 6 lines
long: calyx 5 to 6 lines long, glabrous: sepals nearly equal, oblong of oval,
rounded at apex: corolla white, broadly campanulate, 24 inches broad, with
a short thick tube 1 inch long: capsule oblong, 9 lines long, glabrous, 2-
valved, 4-seeded, separating into 4 carpels: seeds oblong, 4 lines long with the
margins covered with a long reflex coma longer than the seed. Manzanillo,
March 2 to 18, 1891. No. 1342.

Dr. Palmer speaks of this as a tree with a large top, hanging branches, and a
great profusion of flowers. The flowers generally appear before the leaves, but
when both appear together the flowers are found in the axils of the leaves form-
ing short, leafy racemes. It 1s called “Acote” and the bark is used in the prep-
ation of a tea which is taken for diseases of the kidneys.

This species belongs to Choisy’s sub-section Multiloba of Strophipomea as laid
down in DC, Prod, vol. ix. As considered by others, it would be referred to the
section Operculina; for although the capsule is not strictly circumscissile, yet
it is clearly differentiated into an upper and lower part. A. Peter in Engler and
Prantl, Pilanzenf. keeps Operculina distinct from Ipomaa on account of the cap-
sule, but Ido not find that this character holds inthe Mexican species. I. rhodo-
calyx Gray has a very different leaf and corolla from my species, but the capsule
has very thin valves throughout, irregularly breaking apart.

but it agrees with C, Wright’s specimens from Nicaragua collected on the Ring-

Tabebuia donnell-smithii Rose, Bot. Gaz. xvii. 418, t. 26 (1892). A tree 50 to 75
fect high, often 4 feet in diameter: leaves palmately compound on long peduncles
5 to 10 inches long; leaflets 7, very variable in size (the largest on petiolules L
to 34 inches long), oblong to ovate, acuminate, rounded or truncate at base,
serrate, glabrate in age, 2 to 10 inches long, often 3 inches broad: flowers
arranged in a large terminal panicle of small cymes, 8 inches long, with short
glandular-pubescence throughout; eymes few-flowered, with deciduous scarious
bracts; pedicels 6 lines long: calyx closed in bud, deeply cleft and two-lipped
in flower, 6 lines long: corolla yellow, tubular, 5-lobed; tube 1 to 14 inches long;
limb 1} inches broad: stamens 4, included, didynamous; filaments incurved,
glabrous except at base; anther cells glabrous, oblong; sterile filament 1} lines
long: ovary sessile: pods 12 inches or more long, 10-ribbed, glandular-pubescent
and loculicidally dehiscent: seeds in 2 rows. Common on the mountains about
Colima and cultivated about the town. Collected by Capt. John Donnell Smith,
at Cuyuta in the departinent of Escuintla, at an altitude of 200 feet, April,
1890, No, 2070; and, also, by Dr. Edward Palmer, at Colima, January 9 to Feb-
ruary 6, 1891. No, 1098.

This is said to be one of the most beautiful trees of Mexico, and is called
“Primavera,” The flowers are of a beautiful golden yellow, produced in great
abundance, and generally appearing before the leaves. The trees are often large,
sometimes 4 feet in diameter, and the wood very valuable. The trunks are cut
into logs about 12 feet in length and shipped from Manzanillo, in the State of
Colima, to the United States, principally to Cincinnati and San Francisco, where
they are much used for cabinetwork and veneering. The tree is very com-
mon in the lower part of the department of Escuintla; it is tall and slender,
usually leafless, and with the profuse delicate yellow flowers standing out against
the sky like golden clouds,

The following note is from a letter of J.D. Smith, January 7, 1892: “The trees
were too branchless for my servant to climb, too stout for him to fell with his
machete, and too high for me to discern what manner of leaves were those which
occasionally showed themselves among the flowers. My flowers were all picked
upon the ground. I think there must be many trees in those countries of which
botanists have not been able easily to colleet specimens, and which, therefoye,
remain unknown.”

I have not been able to place in any known species this interesting tree. It
seems curious that a tree so widely distributed, of such attractive flowers, and
of some commercial importance should have remained unknown to botanists.
The species, while not agreeing in all respects with Tabebuia, answers better to
this than to any other known genus. In its inflorescence and ribbed pods it is
more like Godmannia and Cybistax, but does not agree in other particulars.

Since the above description of this tree was published by me in the Botanical
Gazette I have written to several New York dealers in imported woods and learn
that they are well acquainted with it. I give two of these letters. Mr. John
R. Graham wrote, under date of December 29, 1892:

347

‘Replying to your postal, ‘Primavera’ or ‘white mahogany’ are the two names
for the same wood, which grows in Mexico. It is used largely in the manufac-
ture of fine furniture and interior decoration. We handle it in the logs and
lumber, also veneers, Worth from 12 cents per foot in the log to 15 to 25 cents
in lumber.”

William E. Uptegrove & Bro. write, under date of December 29, 1892:

‘We do handle ‘ Primavera’ or ‘white mahogany.’ The two names are used
forthe same wood, The former is correct. It is a native of Mexico, That
growing on the west coast is the best. It is used only moderately and costs
somewhat higher than ‘red’ mahogany. We do not consider it a desirable
cabinet wood.”

A condensed account of the original description is given in Hardwood (vol.
iii. 21), by Geo, B. Sudworth.

Prof. C.S. Sargent, in Garden and Forest (vol. VI, p. 12), says:

“In the December issue of The Botanical Gazette there is a figure reproduced
from one of Mr, Faxon’s drawings of a species of Tabebuia, a native of Mexico
and Central America, which Prof. Rose, of the Department of Agriculture,
describes as a new species, and which he dedicates to Mr. John Donnell Smith,
of Baltimore, its discoverer. Vor the last twelve or fifteen years a handsome,
light-colored wood has been imported into the market of San Francisco from the
west coast of Mexico, and is said to have been produced by a tree called ‘Prima
vera,’ This wood, of late years, has been quite extensively brought into the
Eastern markets under the name of ‘white mahogany,’ and is now considered
here one of the most valuable and useful of all cabinet woods. Its origin has

_ long remained unknown, and although there may be still some doubt as to the
identity of white mahogany with the ‘Primavera’ of Manzanillo, Prof. Rose’s
note gives the indication of the direction in which further investigations of the
origin and source of supply of this wood should be made.”

This plant is commonly cultivated in Mexico for its handsome flowers. ;
Parmentiera sp. A small tree, 12 feet high with horizontal branches: leaves in
fascicles of 2 to 5 subtended by a single spine; leaflets 3, obovate, obtuse,
entire or toothed towards the apex; petioles slightly winged, about the length
of the leaflets: pods 10 inches long, yellow. In shady woods about Manzanillo,
March 2 to 18, 1891. No, 1347,

This species differs certainly from P. cereifera and P, edulis, which by some are
considered the only two species; from the former it differs in its pods, acuminate
leaflets and calyx: from the latter, in its pods, etc. Miers considered there
were six species; of these it seems nearest to P. foliolosa, but differs in being
spiny; P. aculeata has similar spines, but its leaflets are often simplé; in P.

‘lanceolata all the leaflets are simple; P. alata has very properly been referred to
the genus Crescentia.

Mr. John Donnell Smith has since written me that he has in his collection two
numbers whick he considers the same as mine, which he has referred to P.
edulis.

ACANTHACES.

long including the short stipe, cinereous-puberulent: seeds 4 (2 to each cell),
much flattened. Armeria, February 15, 1891. No. 1286.

This species has the stamens of Ruellia.

In this species the ovules are only 2 in each cell and only one in each cell

This species is near J. palmeri, but with more acuminate leaves, narrower
bracts, ete.

Justicia paniculata Rose, sp.nov. One or two feet high, much branched, glandular-
pubescent and somewhat villose, older parts with whitish bark and glabrate:

about Manzanillo, December 1 to 31, 1890. No. 892.

These specimens are in fruit, but from some buds the flower characters were
made out. This resembles Carlowrightia, but the stamens seem to place it in
the above genus,

Manzanillo, December 1 to 31, 1890. No. 946.

With only scanty material and scattered descriptions of the various species of
this genus, I think it is best not to name what seems to be a new species.

Dicliptera resupinata (Vahl) Juss. Ann. Mus. Par, ix. 268 (1807); Justicia resu-

lucre 34 lines long: corolla white: capsule 2 to 24 lines long: seeds 4 line in
diameter. Manzanillo, March 2 to 18, 1890. No, 1380a,

Dr. Palmer sends another plant from near the same
place, which differs considerably from it in habit.
Branches very long and sleuder, rooting at the joints:
leaves more oval, on very long petioles, beneath glab-
rate; involucre very pilose, less glandular, the appen-
diculation stronger, In shade at the edge of a lagoon.
March 2 to 18, 1891. No. 1330.

Bentham in Botany Sulphur speaks of this genus as
being a shrub. Our specimens, while the plants are
probably perennial, having a small, indurated root,
can not bear the dignity of shrubs.

The restoration of the Henrya of Nees supplants the
Henrya of Hemsley (Journ, Linn, Soc. xxvi. 111), and
which that author has recently (Bull. Torr, Club, xix, re eee ee
97) renamed Neohenrya. ing the stamens.

Barleria micans Nees in Benth. Bot. Voy. Sulph. 146 (1844).

lanceolate. A very showy plant. Growing in shade. Colima, January 9 to Feb-
ruary 6, 1891. No. 1144.

Dr. Palmer’s notes state that the flowers are sulphur- -yellow, but this must be
a mistake; in the herbarium specimens they area dark violet.

In this species only the 2 anterior stamens are developed, but there are 3 small
scaly hairy staminodia at the base of the corolla.

The seed is called ‘‘Chana” at Colima and Manzanillo, but elsewhere it is
known as “Chia granda.” The ‘‘Chia” proper is the fruit of a Salvia. This
species is collected in considerable quantities and sold in the markets under the
above names. With sweetened water it makes a cool, refreshing drink, much
used by the sick. The roots are also gathered and used medicinally, —

This is a medical plant much used by the Mexicans and sold in the market at
Colima. Itis probably cultivated in the gardens, but it was not seen by Dr,
Paliner in any of his excursions.

The specimen from southern Mexico, doubtfully referred by Mr, Hemsley to
D. parviflorum, could hardly be confused with this species.

Mr. Watson says of it in a letter dated October 23, 1891. “ That must be Piso-
nia aculeata. We have seen the same thing essentially from the West Indies
and Brazil, and the variety hirsutissima is described as having the cymes corym-
bose-capitate.”

I have not seen specimens of C. globosus. My specimens differ from the descrip-
tion of that species in having only 3 stamens and much larger leaves.

* Pisonia aculeata Le Guaymas, April 1 and 2, 1891. No. 175a. Specimens of
this plant are again collected by Dr. Palmer. The following note was sent me by
the late Pr. Watson:

“Cryplocarpus (?) capitatus Watson [Proc. Amer, Acad. xxiv. 71 (1889)]. Fresh
bpecimens of this doubtfully named species, collected by Dr. Palmer at Guaymas,
show it to be a form of the widely-distributed and very variable Pisonia aculeata,
It does not differ essentially from the var, hirsutissima Schmidt. Fl. Bras, xiv. 354,
distinguished by its blunt obovate leaves and dense, short-hirsute pubescence. The
want of spines (they are few on these specimens also), the unusual form of the leaves,
and the presence of only staminate flowers served to effectually disguise Dr. Pal-
mer’s original specimens.””—S. W.

AMARANTACEZ.

Celosia (?) monosperma Rose, sp. nov. Shrub, 8 to 16 feet high, glabrous: leaves
lanceolate, 3 to 6 inches long, acute or shortly acuminate, cuneate at base; pan-
icles terminal large, often 1 foot long, slightly pubescent: bracts and bractlets
ovate, acute, } line long: segments of the perianth oblong, 1 line long, acute: sta-
mens5, united at base into a shallow membranaceous cup; anthers 2-celled; inter-
mediate appendages none: styles none: stigmas 2, reflexed, acute: utricle stipi-
tate, ovoid, compressed, circumscissile, shorter than the perianth: ovule 1, sus-
pended from an elongated funiculus: seed pendulous, lenticular, shining; aril
none.—Very common on the mountains near Manzanillo, December 1 to 31,1891.
No. 887.

The following note has been sent me by Dr. Hans Schinz in regard to this
species:

“T have to thank you very much for having sent me the very interesting
Amarantacee. No doubt your Celosia monosperma is a very interesting and puz-
zling plant, but I also take it for a Celosia. Unfortunately, mostof the flowers
are destroyed by a little beetle, so that I could not make out for sure if the
anthers are 2-celled or 1-celled, but as you say in your description that they are
2-celled it can not be anything else than a Celosia. The Celosia monosperma does
not stand alone, for the different species that were formerly united under the
name Lagrezia generally have but onc or {wo seeds.”

Celosia moquini Guillem. in DC. Prod. xiii. pt. 2. 239 (1849). An upright plant, 4
to 8 feet high: utricle circumseissile: ovules 2. Along fences in river bottoms,
Colima, January 9 to February 6, 1891. No, 1208.

This plant is referred as above, although I have not seen other specimens of
the species.

Very little is known of this species. It was probably collected by Bonpland,
and is No, 354 of Ghiesbreght. The localities from which these collectors obtained
the plant is not known. Perhaps Ghiesbreght obtained his specimens from
near this locality. He seems to have visited Colima, although I find very few
species of this region credited to him. <A type specimen is said to be in Herb.
Mus. Paris.

Moquin was uncertain whether the utricle was circumscissile or not. My
specimens, while not quite mature, clearly show that the utricle is circumscissile,

Only the staminate form of this species was obtained and it can not be defi-
nitely referred here. So far as I can learn, neither this species nor any other
Aenida has been reported from Mexico.

1 have referred my plant as above without having seen any specimens of that
species. It differs from the description in some slight details and it has not
been collected so far north before.

The foliage is rather coarse, but Dr. Palmer writes that the white flowers are
very attractive and he thinks it would be a good plant for ornamental cultiva-
tion.

oblique and more or less tapering at base, glabrous on both sides, with veins
rather prominent beneath; petioles 6 to 9 lines long; sheaths 3 to 4 lines long,
truncate, glabrous, very tardily deciduous: spikes single, 6 to 10 inches long:
perianth 5-parted: stamens 8: fruit sessile, solitary in the axils of the bracts,

18, 1891. Letter G.

Collected in flower by Marcus E. Jones at Manzanillo, June 25, 1891. No.5.
This seems to be an unnamed species.

Coccoloba sp. Diffuse shrub, 5 to8 feet high, glabrous or the younger parts puberu-
lent: leaves thinnish, oblong, 3 to 4 inches long, rounded at apex, oblique at
base, reticulated and puberulent: petiole 2 to 3 lines long: sheath 2-lobed,
puberulent: racemes slender, single or somewhat branching, 4 to 8 inches
long: pedicels 1 to 2 lines long: fruits small, ‘‘red”. Rare. On the moun-
tain sides. Manzanillo, December 1 to 31, 1890. No. 965,

These two species are very similar, but the former may be distinguished from
the latter by its larger, thicker, glabrous leaves and sessile fruit.
Antigonon flavescens Watson, Proc, Amer. Acad, xxii. 446 (1887). A very com-
mon climber found running over bushes and trees in various parts of the
mountains. Manzanillo, December 1 to 31, 1890. No. 980.

ARISTOLOCHIACE.

Aristolochia pardina Duch. Ann. Sci. Nat. ser. 4. il, 47 (1854). A high-climb-
ing shrub; the woody base } inch in diameter, the bark corky; the herbaceous
branches glabrous or alittle glaucous (except the margins, petioles, and axils of
young leaves, these pubescent): leaves orbicular to broadly ovate with broad
cleft, open or closed sinus, 5-nerved, somewhat reticulated, obtuse or retuse*
flowers solitary, axillary, on slender peduncles 14 to 34 inches long: calyx ‘‘old
gold, spotted with brown,” oval, 4 to 5 lines in diameter; tube 9 lines long,
obtuse or acutish; stamens 6; capsule many-seeded, oblong, 15 to 20 lines long:
seeds 3 lines long. Colima, January 9 to February 6, 1891. No. 1247.

Very common in shade on hillside and river bottoms, climbing over bushes,
trees, and fences.

The leaves are not as large as described by Duchartre.

I have not seen specimens of this species, but it has been collected about
Colima by Ghiesbreght and Dugts. The species is only known from this local-
ity. Mr. Hemsley thinks that this is the Guaco mexicana Liebm.

LAURACES).

Sassafridium macrophyllum Rose, sp. nov. A diffuse shrub with numerous stems,
15 feet high: leaves alternate, obloug, 6 to 10 inches long, 1 to 3 inches broad,
cuneate at base, acuminate, ‘‘ emerald-green,” shining, strongly veined beneath;
petioles 3 to 6 lines long: panicles axillary and terminal, 4 to 8 inches long,
including the peduncle; pedicels 3 to 5 lines long: flowers white, sweet-scented,
5 to 6 lines in diameter: calyx 6-parted, the outer considerably larger: perfect
stamens 9, 4-celled, 4-valved, sessile; the three inner with a pair of glands at
base; staminodia 3, capitate——Very abundant in the wet bottom of a small
creek on the opposite side of the bay from Manzanillo, December 1 to 31, 1890.
No. 1033.

The only described species is S. veraguense from Nicaragua, although there are
said to be 2 undescribed species from South America. My species differs from
the above in having nearly all the parts much larger, especially the leaves; the
latter are also acuminate, with stronger lateral veins, but the veinlets are not so
strongly or regularly reticulated.

Meissner, in the original description of the genus (DC. Prod. xv. 171), as well
as Benth. and Hook, (Gen. Plant. iii. 160), states that the berry is unknown.
Charles Wright, however, collected mature fruit in Nicaragua as long ago as
1853-’56. The berry is oblong, glabrous, 6 to 8 liaes long. By some mistake
these specimens of Wright’s were distributed under the name ‘“ Daphnidium
veraguense Meissn.”

Here I am inclined to refer J. N. Rovirosa’s Nos. 35 and 15, although they have
somewhat smaller leaves, and the No. 35 is said to be a tree 8 to 10 meters high.
Rovirosa’s specimens are from Tabasco and were collected November 6 and 20,
1887, respectively.

glabrous: capsule 1 inch broad, crimson. Abundant in certain places in the
rich bottoms. Agiabampo, October 3 to 15, 1890. No. 802.

This species seems near the specimens obtained by Dr. Palmer at Los Angeles
Bay in 1887 and referred to P. macrocarpa by Mr. Watson. It seems very dis-
tinct, however, from that species. .

As first suggested by Mr. Watson, this species seems to include ZL. hindsiana,
and with it also Iam inclined to place the more recent species L. comonduana
Millsp.

As the species is now construed its range extends in Mexico along the coast
from Guaymas to Agiabampo and on both sides of the peninsula of Lower Cali-
fornia as far north as Comondu. The bibliography of this species is as follows:

This is a very peculiar dcalypha. It differs from all other species which [
have scen in its staminal spikes being aments or catkins. They appear as scaly
buds and seem to have been formed at the close of the last growing season. The
flowers seem to develop just before the leaves appear. The position of this spe-
cies in the genus is doubtful; it is perhaps near 4. longipes, which has similar
pedicels and ovaries in the female flowers, but the latter has the flowers arranged
in panicles.

The plant has much the habit of the hazelnut, and hence the specific name.

The following note is taken from F. Pax’s letter of December 28, 1892:

“Indeed, it is a very peculiar plant, not allied with any other species of
Acalypha. There is no, doubt that the plant shows the greatest affinity with
the genus Acalypha: the flowers are identical with those of Acalypha, but the
inflorescence is very unlike. I do not know any other species of Acalypha

358

which has any affinity with your new plant, and I think it is best to place
it in a new subgenus,”

This seems to be the same as Mr. Watson’s species although the leaves are
considerably larger. Mr. Watson afterwards thought that his species was pos-

mens flowered during the summer of 1891; none flowered during 1892, and only
a single specimen flowered during 1893, It 1s a very delicate little plant and
well worthy of cultivation.

This species is near I. harrisiana, but the leaves are glaucous, and not nearly
so wide, of different shape, and with different tip.

[have given «© full description above, as the original reference is very incom-
plete.

The following note appeared in Garden and Forest of January 4, 1893:

“Tt will be of considerable interest to the readers of Garden and Forest to
know that Dr. Edward Palmer has collected what seems to be the little-known
Ayare angustissima (see figure 11). The plant is entirely unknown to the
growers of Agaves, and is only represented in herbaria by the type specimens
in the Engelmann Herbarium at the Shaw School of Botany, St. Louis.

“The following note from Dr. Engelmann, published in the Transactions of the
Academy of Sciences, St. Louis (vol. iii, p. 806), contained all the information
that we previously had respecting this plant:

“Dr, Gregg collected near Ocotillo, direction of Tepic, in western Mexico,
leaves of a plant which he says bears a scape 5 to 6 feet high, and which,
like many narrow-leaved Agaves and Yuecas, was called ‘ Pamilla” by the natives;
unfortunately no flowers came along, butasit seems to be an undescribed Agave,
it may be designated as A. angustissima; leaves 2 to 3 feet long, 2 and 14 lines
wide, convex on the back, filamentose on the margin, narrowed into a short (2}
lines), stout, triangular, brown spine. It seems allied to 4. filamentosa Salm.,
which, however, has much shorter and wider leaves. The form of the terminal
spine precludes its being taken for a Yucea,’

“Dr. Palmer’s plant reaches 12 feet in height. The leaves are numerous in
a dense rosette, the flowers, in pairs, as in A. schotlii, yellow, with linear lobes.
I submitted this species to Mr. J. G. Baker, of Kew, as probably a new species,
who wrote me as follows: ‘We have nothing like this either in the herbarium
or the garden; its nearest affinity is evidently the imperfectly described A.
angustissima, of which we have no specimens.’

“With this suggestion I applied to Dr. William Trelease for the loan of Engel-
mann’s plant. Through his kindness I have been able to examine the type of
this species. I have little hesitancy in referring my specimens here, The type
specimens, however, consist of only a few leaves cut off above the enlarged
base, With such material any comparison is very unsatisfactory, but until
specimens can be obtained from the original station, and it is proved to be dif-
ferent, this plant should stand for A. angustissima.

“Dr. Palmer’s plant was collected at Manzanillo, December 1 to 31, 1890 (No.
1070). The plant is common, growing among rocks, with little soil, along the
margin of the bay. I have some small plants growing in the greenhouses of the
Department of Agriculture.

“Seeds when planted in pans, germinated in seven to ten days. Seeds have
been sent to Kew and to the Shaw gardens, but no report has yet been received.”

Mr. W. Watson, of Kew, also writing in Garden and Forest (vol. vi. p. 76) has
this to say regarding this discovery:

“The picture and full account of this Agave, published in Garden and Forest
(vol. vi. p.5), were highly interesting to growers of succulent plants in this coun-
try, and still more interesting is the fact that, through the kindness of Prof,
Sargent, who sent seeds of it to Kew, it is likely soon to become known in col-
lections here, the seeds having germinated quickly and freely. The offer of seeds
through your pages (vol. vi. p. 6) to any person wishing to grow this plant should
be taken advantage of by all cultivators of such species of agave as A, filifera
and 4. schottii, to which ornamental and compact growers A. angustissima is
closely related. The attention of collectors and botanists generally should be
drawn to the forethought and good nature which attended the rediscovery of
this plant. It is difficult to interest botanical collectors in the introduction of
desirable plants into cultivation.”

PALMACES.

Cocos (?) sp. A tree, sometimes 100 feet high, 12 to 18 inches in diameter: leaves
large and pinnate: sepals and petals 3 each, about equal, broadly ovate, 1 inch
long: disk prominent: fruit oblong, 2 inches long; the husk thin: the wall of
the nut is thick and hard; embryo nearly filling the cavity. Across the bay
from Manzanillo, December 1 to 31, 1890. No. 1063.

I have not been able to place these specimens satisfactorily, not having them
in flower, but they seem to have many of the characters of Cocos. The albumen
has the taste of the common cocoanut, but it is more oily. The central cavity
is almost wanting. The nut is 1-celled and has three eyes near the base.

The nuts are used in making a kind of soap.

It is variously called ‘ coqueto,” ‘Palma de Coquito de aceita,” ‘Coco de
aceita.” I find this form referred to Elawis melanococca in Antonio Garcia Cubas’
“Mexico, its Trade, Industries, and Resources,” It is certainly not that species,
if it really belongs to that genus.

A second species of palm was collected at Manzanillo which I have not been
able to determine generically. Six to eight feet high, spiny: leaves palmate; fruit
4inch in diameter in small, dense clusters: flowers unknown. In low places.

Florida, Karw. 1s an error, The following two species belong to the same
genus :—
