The present series, entitled “Smithsonian Miscellaneous Collec-
tions,” is intended to embrace all the publications issued directly
by the Smithsonian Institution in octavo form; those in quarto
constituting the “ Smithsonian Contributions to Knowledge.” The
quarto series includes memoirs, embracing the records of extended
original investigations and researches, resulting in what are be-
lieved to be new truths, and constituting positive additions to the
sum of human knowledge. ‘The octavo series is designed to con-
tain reports on the present state of our knowledge of particular
branches of science; instructions for collecting and digesting facts
and materials for research; lists and synopses of species of the
organic and inorganic world; museum catalogues; reports of ex-
plorations ; aids to bibliographical investigations, etc., generally pre-
pared at the express request of the Institution, and at its expense.

The assignment of a work to one or the other of the two series
will sometimes depend upon whether the required illustrations can
be presented more conveniently in the quarto or the octavo form.

In the Smithsonian Contributions to Knowledge, as well as in
the present series, each article is separately paged and indexed, and
the actual date of its publication is that given on its special title
page, and not that of the volume in which it is placed. In many
cases works have been published, and largely distributed, years
before their combination into volumes.

NOTLC E:

EXPERIENCE having shown that some years must elapse before this work
can be completed, and a new impression of the part first published Gn
1878) being called for, it is expedient now to issue the two parts, which
together comprise all the Gamopetalous Dicotyledons, in the form of a
single volume, under the auspices of the Smithsonian Institution.

Both parts have been corrected, as far as could well be done upon
the electrotype plates; a supplement of eleven pages is added to the very
recently published Volume I. Part II., and its full index has been made
anew. The tabular enumeration of the contained genera and species has
been transferred to the end of the Gamopetale. To Volume II. Part L, a
supplement of seventy pages is added, and a few pages have been recast; a
tabular enumeration of all the gamopetalous genera and species is appended,
and a complete index of genera, species, synonyms, &c.,— making an

extension from 402 to about 500 pages.

linear, fixed by the base. Capsule 2-celled, septicidal. Seeds downwardly imbricated on the
placenta. :

somewhat irregular epigynous corolla, bearing fewer (1 to 3, rarely 4) stamens
on its tube, an ovary invested by the calyx-tube, and of one to three cells, but
only one ovuliferous, a solitary suspended seed with a straight embryo and no
albumen. Limb of calyx none, or of lobes or teeth, or evolved on the fruit into a
kind of pappus. Corolla either obscurely or manifestly irregular (bilabiately, 3) ;
lobes imbricated in the bud. Filaments and style filiform: stigma undivided and
truncate, or minutely 3-cleft. Ovule anatropous. Fruit dry and indehiscent, a
kind of akene.

anteriorly. Stamens 3. Ovary 1-celled, and with mere vestiges of two lateral cells, ripen-
ing into a flattened akene, which is mostly l-nerved on one face, 3-nerved on the other,

OrpeR LXXII. DIPSACACE.

Herbs (all of the Old World); with opposite or verticillate leaves, no stipules,
capitate and involucrate inflorescence ; the flowers subtended by bracts, and each
with a more or less obvious involucel, hermaphrodite ; calyx-tube adnate to the
one-celled simple ovary; corolla epigynous ; stamens inserted on its tube alter-
nate with its lobes, of equal number or fewer, wholly unconnected ; style fili-
form and stigma simple; ovule solitary and suspended, anatropous ; seed with
a straight embryo in fleshy albumen. Corolla irregular or nearly regular; the
lobes imbricated in the bud. Fruit an akene, more or less adnate to the involucel
which embraces it.

Scaniésa arropurrtrna, L., Sweet Scaprous of the gardens, is familiar; and one
or two of the following genus have become spontaneous.

1. DIPSACUS, Tourn. TrEasEt. (Greek and Latin name of Teasel, said
to come from duds, thirsty.) — Flowers in a terminal head or short spike, in which,

48 DIPSACACEA. Dipsacus.

however, the anthesis is not simply centripetal; the sabtending bracts and those

of the conspicuous polyphylous and unequal involucre spinescent. Involucel

ealyx-like, prismatic, truncate and crenulate at the border, enclosing the whole
ovary and fruit, at length adnate to its thin walls. Calyx-limb cup-like, 4-toothed

or lobed. Corolla tubular-funnelform, 4-lobed, nearly regular. Stamens 4.

Stigma lateral. Coarse and rough or prickly biennials, with cauline leaves

mostly connate and cup-like at base.

D. sytvésrris, Miiu. Prickly, 3 to 5 feet high: leaves lanceolate-oblong: involucre longer
than the head: flowers flesh-colored: bracts of the receptacle tipped with a long and straight
flexible awn. — Roadsides of the Eastern States: fl. summer. (Nat. from Eu.)

D. vuLiénum, L. (FuLier’s Trasreu.) Probably an ancient derivative of the preceding:
involucre usually shorter than the cylindraceous head, at length reflexed: bracts of the re-
ceptacle rigid-spinescent, the tips recurved or hooked; whence useful for raising a nap on
woollen cloth. — Escaped from cult. in some places, apparently established in 8. California.

Orper LXXITI. COMPOSIT A.

Flowers in an involucrate head on a simple receptacle, 5-merous or sometimes
4-merous ; with lobes of the epigynous corolla valvate in the bud; stamens as
many as corolla-lobes and-alternate with them, inserted on the tube; anthers con-
nate into a tube (syngenesious); style in all fertile flowers 2-cleft or lobed at sum-
mit and bearing introrse-marginal stigmas; ovary one-celled, a smgle anatropous
ovule erect from the base, becoming an exalbuminous seed with a straight embryo,
the inferior radicle shorter and narrower than the cotyledons ; the fruit an akene.
Tube of calyx wholly adnate to the ovary ; its limb none, or obsolete, or devel-
oped into a cup or teeth, scales, awns, or capillary bristles. Corolla with nerves
running to the sinuses, then forking and bordering the lobes, rarely as many
intermediate nerves. Anthers commonly with sterile tip or appendage; the cells
introrse, discharging the pollen within the tube; this forced out by the lengthen-
ing of the style, which in hermaphrodite and male flowers is commonly hairy-
tipped or appendaged. Pollen-grains globose, echinulate, sometimes smooth, in
Cichoriacee 12-sided. Leaves various: no true stipules. Development of the
flowers in the head centripetal ; of the heads, when clustered or associated, more
or less centrifugal, i. e. heads disposed to be cymose. Juice watery, in some
resinous, in the last tribe milky.

Heads homogamous when all its Jowers are alike in sex; heterogamous when
unlike (generally marginal flowers female or neutral, and central hermaphrodite
or by abortion male); androgynous when of male and female flowers ; monactious
or diwcious when the flowers of separate sexes are in different heads either on
same or different plants ; radiate when there are enlarged ligulate flowers in the
margin; wholly digulate when all the flowers have ligulate corollas; discoid
when there are no enlarged marginal corollas. When these exist they are some-
times collectively called the ray: the other flowers collectively occupy the disk.
The head (compound flower of the early botanists), in Latin eapitulum, is also
named anthodium. Its involucre (perielinium of authors) is formed of separate
or sometimes connate reduced leaves, i. e. bracts (squame@ or scales of De Can-
dolle, &c.): the innermost of these bracts subtend the outermost or lowest flowers.
The axis within or above these is the receptacle (elinanthium of some), which

varies from plane to conical, or oblong, or even cylindrical or subulate. When the
receptacle bears flowers only, it is xaked, although the surface may be alveolate,
Joveolate, or merely areolate, according as the insertion of the ovaries or akenes
is surrounded or circumscribed by honeycomb-like or lesser elevations; or, when
these project into bristles, slender teeth, or shreds, it is fimbrillate: it is paleaceous
when the disk-flowers are subtended by bracts; these usually chaff-like, therefore
called palee, chaff, or simply bracts of the receptacle. In place of calyx-limb
there is more commonly a circle of epigynous bristles, hairs, or awns, the pappus,
a name extended to the calyx-limb of whatever form or texture: its parts are
bristles, awns, palez, teeth, &c., according to shape and texture. Corollas either
all tubular (usually enlarging above the insertion of the stamens into the throat,
and 4—5-lobed at summit, mostly regular); or the marginal ones strap-shaped,
i. e. Ligulate, the elongated limb (ligule) being explanate, and 3-5-toothed at the
apex. Such are always female or neutral, or, when all the flowers of the head
have ligulate corollas, then hermaphrodite. Anthers with basal auricles either
rounded or acute, or sometimes produced into tails (caudate). Branches of the
style in female flowers and in some hermaphrodite ones margined with stigma,
i. e. stigmatic lines, quite to the tip; in most hermaphrodite flowers these lines
shorter, occupying the lower portion, or ending at the appendage or hairy tip.

eighth of those of North America.

S. LATERIFLORA, L. Spec. ii. 879, is Aster diffusus, Ait.
S. Novesoracensis, L. 1. c., is probably Aster Tartartcus, and not North American.

Species founded on garden plants and not identified with, or obviously referable to, North
American originals, are the following : — .

S. ampicua, Ait. Kew. ili. 217, cult. 1759 by Miller, of unknown source, appears to have been
some European form of S. Virgaurea, although later plants cultivated under this name may be
derivatives of S. latifolia, L.

S. evifierica, Ait. Glabrous and smooth up to the flowering branches, 2 or 3 feet high,
equably leafy: leaves of rather firm texture, oval or oblong, acuminate at both ends, the larger

identified as indigenous. The typical form is here taken to be that of the Banksian herbarium,
cult. hort. Kew. 1778. A second original specimen, to which the syn. Mill. Dict. belongs, is

S. recuRVATA, Willd., and S. rfvipa, Willd. (Enum. 889 & 491), described from cultivated
plants, are referred to under S. ceesia, L., p. 145.

S. nirnospermMirotra, Willd. Enum. 891, referred to under S. sempervirens, L., was prob-
ably derived from that, under cultivation becoming pubescent and duller green. But without
the transitions as seen in S. integrifolia, Desf., this would seem improbable.

S. corymposa, Poir. Suppl. v. 461 (not Ell.), is only the European S. Virgaurea, L.

S. gRanpIrLORA, Desf. Cat. ed. 3, 403, of unknown source, is evidently a tall cultivated state
of the Italian S. littoralis, Savi.

S. ruscAra, Desf. 1. c. 402. Glabrous and very smooth (the inflorescence barely puberulent) :
stem 3 or 4 feet high, with numerous ascending purplish branches, very leafy : leaves oblong-
lanceolate, acute at both ends or acuminate, entire, or the lower (3 or 4 inches long) with a few
minute and obscure teeth, of somewhat firm texture, and minutely reticulated inconspicuous
venation, a pair or two of primary veins more evident: heads hardly 3 lines long, numerous in
a narrow or virgate thyrsus, not secund: bracts of the involucre rather broad (outer oblong)
and obtuse: rays 6 to 8, short: young akenes puberulent.— Of unknown source; cult. in Paris
Garden from 1828. Habit somewhat of S. puberula.

heads are barely half-inch long.

Var. leptdotes, Gray, is an ambiguous form from Middle Park, Colorado (Parry),
with heads less than half-inch long, and all but the primary ones somewhat distinctly pedun-
culate: leaves narrowly linear with attenuate base. Perhaps a distinct species.

foliose-fulcrate hemispherical heads (these merely half-inch high): bracts of the involucre
lanceolate, mostly obtuse: pappus of ray and disk alike and of equal length, rather rigid, about
the length of the akene (2 or 3 lines long). — Proc. Am. Acad. xvi. 85.— Arizona, adjacent

The line between Aster and Frigeron is arbitrary. Aster is far the most difficult of our
genera, both for the settlement of the names of the species and for their limitation, in respect
to which little satisfaction has been attained as the result of prolonged and repeated studies.
For full reasons why the following Linnean species subside, see Proc. Am. Acad. xvii. supra cit.

A. pivaricdtus, L. Founded, as to the specimen in the herbarium, upon the upper part
of a plant of A. corymbosus, Ait., wanting the cordate serrate leaves; as to the plants of Pluke-
net and Gronovius, upon A. infirmus, Michx.

A. rfagipus, L. Founded wholly upon Clayton’s plant as described in Fl. Virg.; is a mere
synonym of A, linariifolius, L.

A. trnirortus, L.,and A. nyssopir6cius, L. Mant., belong to Galatella, and are not Amer-
ican. The plant of Gronoy. Fl. Virg., referred to, is A. tenuifolius, L.

A. Annuus, L., is well known as Erigeron annuus.

A. vernus, L., is Erigeron nudicaulis, Michx.

A. murApitis, L. Not to be found in the Linnzan herbarium. In the first ed. of the Spec.
Pl. was compared with an “A. serotinus,” which was neither published nor preserved in the her-
barium, has as a synonym a plant figured by Plukenet which is not preserved in his herbarium:
finally, in ed. 2, the character was reconstructed in a manner incompatible with the original
one, and before the Plukenetian synonym “ Herm. Hort. Lugd. t. 67” was introduced, which,
on the authority of the herbaria of Royen and of Sherard, is A. /evis, L., and the comparison
was changed to one with A. Tradescanti, L. A. mutabilis of later authors belongs to older-
named species.

A. Miser, L. Founded wholly upon a much exaggerated figure in Dillenius, with fictitious
character, drawn from the plate. See A. vimineus, var. foliolosus.

A. citiAtus, Walt. Car. 209, is not at all identified.

heads and thinner leaves appear to pass into A. corymbosus. A robust form, with large
heads, more glandular involucre and peduncles, upper leaves ovate and sessile, lower and
petioled cauline leaves all rounded at base, and most of the radical ones little cordate (A.
macrophyllus of Willd. herb. chiefly, the rays perhaps violet), comes near the next following.

§ 6. AsTER proper. Heads various: bracts of the involucre (or at least the
outer ones) with green herbaceous tips or appendages, or wholly or partly foli-
aceous, imbricated or pluriserial, their margins not scarious: akenes from obovate-
oblong to linear, 3-several-nerved: pappus rather fine and soft, or in the first
subsection more coarse and rigid, simple, i. e. with no exterior setulose series. —
§ Aster proper, with part of Oritrophium & Calliastrum, Torr. & Gray, FI.
Probable hybrids abound.

* 1. Involucre well imbricated; the bracts appressed and coriaceous, with short and abrupt mostly
obtuse herbaceous or foliaceous spreading tips (the outermost sometimes loose and more foli-
aceous): akenes narrow, 5-10-nerved, from minutely pubescent to glabrous: pappus mostly
more rigid than m any of the following: rays showy, blue or violet: leaves of firm texture,
more or less scabrous (the last species excepted), none of them cordate or clasping (§ Calli-
astrum, Torr & Gray, FI. ii. 106, excl. spec.). — SPECTABILES.

+— Radical and lowest cauline leaves ovate or ovate-oblong, some with rounded base, or even sub-
cordate: heads half-inch high: involucre nearly hemispherical; the green tips of the involucral
bracts very short and either indistinct and erect or abruptly spreading: stems a foot or two
high. Transition to Biotia, possibly hybrids of the preceding species with true Asters, being
local and rare, but if so the other parent not at all determinable.

lar-puberulent: leaves minutely or obscurely serrate; radical and lowest cauline ovate on
slender naked petioles; upper lanceolate: heads loosely corymbiform-cymose: involucral
bracts all erect and with less distinct close tips, pulverulent-glandular ; the short outer oblong-
linear: rays 15 to 24, narrow, half-inch long, lilac or violet. — Man. ed. 5, 230. Eurybia

leaves) ; Nutt. Gen. ii. 155. A. fragilis, Lindl. Bot. Reg. t. 1537, & herb. — Border of moist
or dry woods, New England and W. Canada to Florida and Texas. Runs into various
forms, such as

Var. coridifolius, Torr. & Gray, l.c. A more rigid and effuse Southern form,
with rather coriaceous leaves, especially the very small ones of the elongated branches and
branchlets; involucral bracts also more rigid. — A. coridifolius, Michx. Fl. ii. 112; Willd.

fig. 3. — Pine barrens, 8. Carolina to Florida and Louisiana.

Var. subulefolius, Torr. & Gray, l.c. Rather rigid form, with ascending flower-
ing branches, on which the somewhat large heads are often subracemosely paniculate and
bearing erect or little spreading subulate-linear or linear-oblong very small leaves. — Open
woods and pine barrens, Carolina to Texas; also N. W. Arkansas. The var. subracemosus,
Torr. & Gray, 1. c., was made up of specimens, some fairly referable to the present form,
others to A. vimineus, var. foliolosus, or of intermediate forms.

4+ ++ Heads racemosely unilateral, usually numerous or crowded along the flowering branches;
the branchlets or minutely leafy peduncles shorter or little longer than the inyolucre: disk-
flowers apt to turn purple.

A.racemosus, Exrt. Minutely scabrous-pubescent along the numerous slender erect or
ascending branches, probably rather tall (base of stem unknown): leaves rigid, linear,
small, acute, entire: heads small (little over 2 lines high), somewhat spicately or more
loosely racemose: involucre hemispherical and of narrower and acuter bracts than in the fol-
lowing: rays only a line or two long, purplish. — Sk. ii. 348; Torr. & Gray, Fl. ii. 127.—
S. Carolina to Florida and Louisiana, in the low country or along the coast. Perhaps also
Texas, but specimens (of Lindheimer) insufficient. Species insufficiently understood.

A. vimineus, Lam. Nearly glabrous: stem 2 to 5 feet high, slender, simple, with nu-
merous usually horizontal foliolose flowering branches, bearing numerous usually crowded
heads: leaves linear or narrowly lanceolate, entire, or the lower with few serratures (the longer
cauline 3 to 4 or 5 inches long, 2 to 4 lines wide): heads 2 or 3 lines high: bracts of involucre
linear, usually acutish: rays commonly pure white (not rarely changing to purplish, even
on a part of the plant), about 2 lines long. — Dict. i. 306 (1783, form with somewhat lanceo-
late cauline leaves); Gray, Proc. Am. Acad. xvii. 169. A. T’radescanti, L., as to one speci-

gilis, Nees, Ast. 101, in part, not Willd. — Moist ground, Canada to Florida and west to
Arkansas, most common northward; flowering rather early.

Var. foliolésus. Leaves linear, entire: branches ascending, bearing sparse or more
paniculate heads: consists of forms intermediate between A. vimineus and A. dumosus, but
with smaller heads than is usual in the latter, and thinner as well as narrower involucral
bracts. — A. foliolosus, Ait. Kew. iii. 202. A. ericoides, Meliloti agrariea umbone, Dill. Elth.

specimen in herb. Sherard; which is said to have been raised from New England seeds. A.
dumosus, var. subracemosus, Torr. & Gray, Fl. ii. 128. - New England to Illinois.

A. diffisus, Air. Either pubescent or almost glabrous, a foot to 4 or 5 feet high; the
larger plants widely and divergently branched: leaves thinnish, mostly broadly lanceolate
or wider, with much narrowed base, acute or acuminate; lower cauline generally 3 to 5
inches long, sparingly and acutely serrate; those of the flowering branches becoming small
and entire, some of them surpassing the crowded or sometimes more scattered heads, which
are usually disposed along the length of the flowering branches, either singly or in clusters ;
radical leayes ovate and slender-petioled; involucre campanulate ; its bracts linear, obtuse or
sometimes acutish, and with a definite short green tip: rays small, white, or sometimes
tinged with purplish or violet.— Ait. Kew. iii 205; Nees, Ast. 1.c¢., &c. A. divergens, Ait.

A. parviflorus, Darlingt. Fl. Cest. 446, not Nees. Solidago lateriflora, L. Spee. ii. 879. —
Dry or barely moist ground, Canada to Texas and west to Missouri. <A. diffusus is, on the
whole, the best of three names of same date.

Var. horizontalis. A robust, very bushy-branched and exceedingly floriferous
cultivated form ; the leaves thickish, those of the widely spreading flowering branches small
and short, entire: white rays more conspicuous. — A. horizontalis, Desf. Cat. ed. 3, 402. A.
recurvatus, Willd. Spee. iii. 2047.— A plant of the gardens, not exactly matched by indige-
rous specimens, but evidently of this species.

Var. thyrsoideus. From slightly to distinctly cinereous-pubescent: leaves from
ovate-oblong to lanceolate: flowering branches ascending, rather rigid, either short or some-
what elongated: heads thyrsoid-paniculate or spicate-glomerate, less secund.— Part of A.
miser, var. glomerellus, Torr. & Gray, 1. c.— New York to Illinois and Upper Canada. West-
ern forms connect with the next species.

Var. hirsuticatlis (A. hirsuticaulis, Lindl. in DC. Prodr. v. 242, and A. miser, var.
hirsuticaulis, Torr. & Gray, Fl. 1. ¢.), founded only on specimens from Albany, N. Y., Beck,
in herb. Torr. & Lindl., is a singular form, probably growing in much shade, with long and
narrow leaves, as of A. vimineus, the midrib of these beneath and the stem very hirsute.
Other forms in Torr. & Gray, Fl., are ambiguous between this and A. vimineus.

Var. bifrons. A luxuriant form, growing in shady and moist grounds, with large
and thin elongated-lanceolate leaves, and spreading branches with loosely disposed and mostly
larger heads: a transition to the following section and to A. paniculatus, Lam. — A. bifrons,
Lindl. in DC. Prodr. vy. 243.— Shady banks of Kentucky River (Short) to Iinois.

+ + + + + Involucre various, in some imbricated and with short close tips, as in the last
preceding section, in others more loose and herbaceous: heads when numerous either thyrsoid-
or open-paniculate on erect or ascending branches. —Vulgares.

++ Cauline leaves sessile, but neither with cordate or auriculate base (except in forms of A. Novi-
Belyit and A. foliaceus), nor with abrupt winged-petiole-like lower portion.

= Atlantic United States species, with branching stems or several or many heads when well de-
veloped, none alpine or subalpine: herbage disposed to be glabrous, but branches often pubes-
cent in lines.

a. Involucre of the small or middle-sized heads close and erect; its bracts narrow. imbricated in
successive lengths, the small green tips not dilated nor spreading. Species seemingly confluent
in a series.

A. Tradescanti, L., partly. Stem slender, 2 to 4 feet high, with numerous erect or ascend-
ing branches and branchlets: leaves lanceolate or linear, slightly serrate or entire, thinnish :
small heads numerous, corymbosely or somewhat racemosely paniculate, only two or three
lines high: bracts of the involucre linear, acutish, partly green at tip and down the back:
rays white, or sometimes tinged with: lilac, only about 2 lines long. — Spec. ii. 876 (as to
Hort. Cliff. in part, if herb. Cliff. is of any authority, and as to syn. A. Virginianus parvis

A. tenuifolius, var., in part, Torr. & Gray, 1. c. 132, not of others. — Open grounds, Canada
to Virginia, Illinois, and Saskatchewan. Cult. from earliest days in European gardens.
Some forms, both cult. and wild, show affinity to A. dumosus, vimineus, and diffusus; others
differ from the next following species only in the smaller heads and flowers.

A. paniculadtus, Lam. Stem 2 to 8 feet high, freely and paniculately branched: leaves
from elongated oblong to narrowly lanceolate, mostly attenuate-acuminate, sharply serrate
or denticulate, or upper entire, thin: heads about a third of an inch high, in loose and open
mostly leafy panicles: bracts of the involucre narrowly linear, with tapering acute or acumi
nate green tips (or outermost wholly green on back): rays 3 or 4 lines long, white varying
to purplish or pale violet (in drying often turning blue). — Lam. Dict. i. 306 (1783, the char.
not good for the involucre, but it is the A. serotinus procerior, &c., Tourn., cited by Lam.) ;

A. simplex, Willd. Enum. 887, and probably A. strictus, Poir. Suppl. 498,—represents a

form of this same species, either very early naturalized in Hungary and Germany, or possi-

bly indigenous. A. /axus, Willd. Enum. 886, seems to be a similar form.— Low or moist
ground, New Brunswick to Saskatchewan, E. Montana, and Louisiana, abundant in the

Northern States, an polymorphous. A small and slender form, in Northern sphagnous

bogs, with linear leaves, resembles A. longifolius in habit and foliage.

A. salicifolius, (Lam.?) Arr. Resembles the preceding, equally branching: leaves com-
monly less elongated, less serrate or entire, of firmer texture, apt to be scabrous, and the
fine reticulation of the veinlets manifest: involucre more imbricated; its bracts firmer,
linear, with shorter and more definite green tips, these acute or obtusish: heads (as large as
in preceding or broader) disposed to be thyrsoid or racemose-glomerate on the ascending
branches: rays purplish to violet, rarely white. — Lam. Dict. 1. ¢.? (no Lamarckian speci-

DC. Prodr. v. 242, narrow-leaved form. A. carneus, in part, & A. Greenei, Torr. & Gray, Fl.
ii. 134. — Low grounds, Canada and New England to Saskatchewan, E. Montana, and Texas:
most abundant in the Mississippi valley. The original of Ait. Kew., in the Banksian her-
barium, is of flowering branches only, with small leaves.

Var. subasper. A rigid and commonly scabrous form, with thyrsoid-contracted and
foliose inflorescence: broad heads commonly foliose-bracteate: bracts of involucre broader
and firmer, often obtuse: rays violet.— A. subasper, Lindl. in Comp. Bot. Mag. i. 97, & DC.
Prod. v. 257. A. carneus, var. subasper, Torr. & Gray, 1. c. — Illinois to Texas.

Var. ceeruléscens. A strict and rigid form, with the rather large heads in a more
naked inflorescence, and leayes all entire: involucral bracts with narrower acute or acutish
tips. — A. cwrulescens, DC. Prodr. v. 235.— Rocky banks, E. to W. Texas, Berlandier, Lind-
heimer, &c.

6. Involucre of the small or barely middle-sized heads looser and less imbricated; but its bracts
erect or hardly at all spreading, narrew and linear, with acute and not at all dilated green tips,
or outermost wholly herbaceous, these little shorter or equalling the inner: leaves linear or lan-
ceolate, not rigid, not dilated at base, sparingly denticulate or entire.

A. janceus, Air. Slender, a foot to a yard high, the smaller plants simple-stemmed and
with few heads, smooth and nearly glabrous: leaves linear or nearly so (3 to 5 inches long,
2 to 4 lines wide), entire, or lower with rare denticulations : involucre 3 lines high ; its bracts
all small, narrowly linear and erect, thinnish, manifestly imbricated in 2 or 8 series, and the
outer more or less shorter (thus connecting with A. paniculatus of the preceding subdivis-
ion): rays light violet-purple, 4 or 5 lines long. — Hort. Kew. iii. 204, the indigenous speci-

Canada and N. New England. Like other boreal species, flowers early when cultivated in
lower latitudes.

Var. villicatilis. A small and low form, with simple stem (a foot or less high) and
midrib of narrow leayes beneath densely white-villous: heads few or solitary: rays deep
violet. — Northern Maine, at Fort Kent, Miss Furbish.

c. Involucre of the middle-sized heads of firmer and more herbaceous or foliaceous-tipped and linear
to spatulate bracts, imbricated in few to several series, of more or less unequal length, their
summits from slightly to squarrose-spreading: leaves of rather firm texture: rays violet: com-
paratively late-tlowering.

A. Novi-Bélgii, L. Rather low, rarely tall, glabrous and smooth, or pubescent in lines on
the branches: leaves from oblong to linear-lanceolate, entire or sparsely or obscurely ser-
rate; upper with sessile base partly clasping and not rarely somewhat auriculate: heads
mostly 4 or 5 lines high and bright blue-violet rays of equal length. —'The commonest later-
flowered blue Aster of the Atlantic border, in low or wet grounds, truly polymorphous, both

original Leyden type, the common form away from influence of salt water, and with leaves not

and linear involucral bracts with narrow and acute spreading or recurving upper portion. —
Common in wet grounds, New Brunswick and Canada to Georgia, chiefly eastward, but ex-
tending to Ohio and Illinois. A. eminens, var. virgineus, Lindl. Bot. Reg. t. 1656, appears to
be a nearly white-rayed form. A. /arus, Torr. & Gray, Fl. ii. 154, a very narrow-leaved

Var. levigdtus. Smooth and glabrous throughout or nearly so: leaves mostly ob-
long-lanceolate, little if at all thickened; upper cauline disposed to be half-clasping by an
abrupt or obscurely auriculate base: involucral bracts in few ranks, rather short, all not far
from same length, loosely erect, and with comparatively short acutish herbaceous tips; thus
resembling A. versicolor except that the involucral bracts are much less imbricated and little
unequal. — A. levigatus, Lam. Dict. i. 306; Poir. Suppl. i. 498, not Willd. &e. A. mutabilis,

Newfoundland to New England: hardly any wild specimens exactly answering to the plant
cultivated and even naturalized in Europe ; but many that connect with the following, viz. : —

Var. litéreus. Stems rigid, low, or sometimes 3 or 4 feet high and then paniculately
much branched, very leafy: leaves thickish and firm, very smooth (rarely upper face some-
what scabrous), oblong to lanceolate, upper partly clasping and sometimes auriculate : bracts
of the involucre loosely imbricated in several ranks, outer commonly spatulate, all but inner-
most with broadish or obtuse herbaceous and mostly thickish tips. — A. Novi-Belgii, L., as

the wild; and a dwarf form, very floriferous, with small leaves and small heads, is A. cespi-

tosus of the gardens (as cited by Lindley under A. adulterinus), probably the parent also of

A. Novi-Belgii, var. minimus, of the gardens, with rose-purple rays. — Saline marshes and

shores, Canada and New England to Georgia: evidently passes into the thinner-leaved form

taken as the type, wherever it recedes from the influence of brackish water. ‘The old culti-
vated forms evidently much altered in the European gardens.

Var. elddes. Slender, a foot or two high and simple, sometimes taller and with
ampler panicle: leaves thickish, long and narrowly linear (2 to 5 inches long, 2 or 3 lines
wide), entire; those of flowering branches or open panicle small and bract-like : involucre of
rather well-imbricated narrow bracts, with short and mostly spreading acutish tips. — A.
elodes, Torr. & Gray, FI. ii. 136, chiefly. A. longifolius, Gray, Man. 233, in part, not Lam. —
Swamps near the coast, New Jersey to Virginia. Would seem to be a most distinct species ;
but passes by gradations into forms of the type of the species, with narrow-lanceolate den-
ticulate leaves of thinner texture; and the broad-leaved var. of Torr. & Gray, 1. c., into the
preceding variety.

Var. thyrsiflorus. Very leafy, smooth: cauline leaves narrowly lanceolate or
nearly linear (2 to 4 inches long, 2 to 4 lines wide below the middle), attenuate-acuminate,
commonly serrulate, of rather firm texture: heads numerous in a narrow thyrsoid panicle,
or somewhat racemosely paniculate on elongated branches, rather large: involucre of the
narrow bracts with attenuate and spreading or squarrose-recurving tips, as in the typical form.

none broadened at the insertion. |

A. Chamissonis, Gray. Rather tall (2 to 4 feet high), with loosely spreading branches
and branchlets, pubescent with spreading hairs or glabrate: leaves bright green, broadly
lanceolate (larger cauline 3 to 6 inches long and an inch or less broad, those of flowering

A. Menziésii, Lixpt. A foot or two high, strict, from cinereous-pubescent throughout
to almost glabrous, bearing mostly numerous or thyrsoidly racemose-paniculate and rather
small heads on rigid erect branchlets or peduncles: leaves lanceolate or the lower spatulate-
oblong (2 or 3 inches long), on the branches small and linear or reduced to linear-subulate,
so that the well-developed panicle is comparatively naked: involucre seldom over 3 lines
high, short-turbinate, of linear slightly spatulate bracts in several rather closely imbricated
ranks, nearly all obtuse: rays violet or purple, 3 lines long. — Hook. Fl. 11. 12, & DC. Prodr.

branching, bearing few or rather numerous loosely paniculate or subcorymbose heads (these
4 or 5 lines high): leaves of firm and thickish texture (veins obscure), linear to spatulate-
lanceolate, entire, with margins commonly hispidulous-ciliate or scabrous: bracts of the

The first of the following species may fairly retain the now established name,
rather than have a new one made; but Conyza bifrons was founded by Linneus
on European Jnule, viz. on Hermann’s figure, which in ed. 2 he refers to that
genus, and on one of Plukenet’s (mistaken for Canadian), which is certainly
I. bifrons, as his herbarium shows. Of the many names for our second species,

much branched, with alternate entire leaves, either corymbed or paniculate short-
peduncled heads from upper axils, and whitish or yellowish flowers. ‘To these

G. Catalinénse. Herbaceous perennial, hispidulous-puberulent or glabrate, unarmed:
stems erect, 3 or 4 feet high, mostly simple with short flowering branches which little sur-
pass the larger leaves ; its nodes usually with a tumid ring: leaves in fives or fours, narrowly
oblong, obtuse, mucronate, one-nerved (rarely by the union of two leaves 2-nerved), either
sessile by a contracted base or short-petioled; at the insertion within bearing some obscurely
glandular bristle-shaped appendages: flowers on short slender pedicels, perhaps polygamous :
corolla white {2 lines in diameter): young fruit sometimes naked and smooth, sometimes
beset with soft and straight bristles of about the length of the body. — Island of Santa Cata-

actly the typical plant (which also occurs in the same region), except that, in addition to the
subradical heads, some elevated 3-4-cephalous shoots have developed.

48. ASTER. P.172, &c. The following omitted names to be added in
their places, chiefly as synonyms.

A. intypdcrus, Kunth & Bouché, Adn. Ind. Sem. Hort. Berol. 1845, & Ann. Sci. Nat.
ser. 3, v. 358, according to an original specimen, is A. Tartaricus, L. f., wrongly taken for
North American.

A. satsucinosus, Less. in Linn. vi. 124 (not Richards.), is A. Sibiricus, L., fide Herder.

A. GRAVEOLENS, Nutt. Trans. Am. Phil. Soc. ser. 2, vii. 294, is a syn. of A. oblongifoltus,
Nutt., on p. 178.

A. pubiscens, Nees, Syn. Ast. 16 (A. heterophyllus, var. Nees, Ast. 55), is a form of A. sagitti-
folius, Willd., p. 182.

A. piniroé.tus, Nees, Syn. Ast. 29 (referred to A. Tradescanti in Nees, Ast. 103), seems to
be A. polyphyllus, Willd , p. 184.

A. anctsrus, Nees, Syn. Ast. 26 (referred, along with A. rigidulus, Syn. Ast. 29, to A. belli-
diflorus in Nees, Ast. 97, seems to be a cultivated form of A. paniculatus, Lam., p. 187.

A. EMINENS, Nees, Ast. 87, is a mixture. The leading form is either A. junceus, Ait. (cited
by Nees as a synonym), or A. paniculatus, to which some of the varieties seem to belong; the
var. levigatus is our A. Novi-Belgii, var. levigatus (to which his synonym points); other forms
are more obscure.

A. LuxUrIANs (Spreng. Syst. iii. 538), Nees, Ast. 538, is a broad-leaved form of A. Novi-
Belgit.

A. UMBELLATUts, Mill., should have the syn. supplied: Dallingeria umbellata, Nees, Ast. 178,
a broad-leaved form.

A. viraArtus, Nees, Syn. Ast. 27 (not Ell.), is a form of A. Novi-Belgii, L., p. 189.

The above determinations from Nees were derived from a set of cultivated Asters supplied
by Nees to Hohenacker (either directly or indirectly), thence to Dr. Klatt, who obligingly gave
them to the author.

A. HAypent, Porter in Hayden, Geol. Rep. 1871 (published 1872), 485, is a syn. of A. pul-
chellus, Eaton, p. 201.

G. triloba, Gray, p. 269, has a thick perennial root, and should be transferred to the second
division, after G. tenu/folia.

G. encelioides, Gray, and the division under which it stands, are to be suppressed, as also
Viguiera tephrodes, p. 271. See Helianthus, infra.

104. HELIANTHUS, L. After H. debilis, p. 273, add: —

H. peaxpArus, Gray, p. 280. Collected in excellent specimens by E. L. Greene, 1885, on
Cape San Quentin, Lower California; the foliage very silvery and soft with the dense pannose
tomentum. From the habitat, the Encelialike aspect, and the whole description, this is evi-
dently Encelia nivea, Benth. Bot. Sulph. 27, the new specimeus with peduncles even longer than
described, and the bracts of the involucre come near to oyate-lanceolate. The small and narrow
palez of the pappus are so very caducous from the ovary that Bentham overlooked them.

cence, not at all lemon-scented: rays “3 to 5, greenish-yellow”: bracts of receptacle uncon-
nected: akenes of disk and ray similar, larger than in related species (2 lines long), turgid
oval, obscurely gibbous, subterete, very obtuse or retuse at both ends, wholly destitute of
terminal apiculation and of basal stipe or callus, not at all angled, or in ray-akenes a very
obscure ventral ridge. — Madia anomala, Greene, Bull. Calif. Acad. i. 91.— California, on
hills and mountains in El] Dorado and Lake Co., Mrs. Layne-Curran. The akenes confirm

15 or more in a circle, slightly united below: rays 14 to 20: disk-flowers numerous: akenes
of the ray rugose-tuberculate at maturity, indistinctly triangular, with a prominent upturned
beak ; those of the disk sterile, bearing a pappus of about 10 subulate-linear palex of half
the length of the corolla.— Proc. Am. Acad. xii. 162, from dwarf or early specimens. —

127. LAYIA, Hook. & Arn.

L. heterdtricha, Hoox. & Arv., p. 315. Pubescence all short and fine; hispid or hirsute
hairs none or few in the original specimens, but moderately developed in a form which is
distinguished from L. glandulosa, chiefly by the want of crisped wool to the pappus.

Var. major. Robust, the copious pubescence all short: heads and rays large: pappus
more or less deciduous from the disk-akenes in a ring at maturity (which the original of the
species also shows). — L. graveolens, Greene, Bull. Calif. Acad. i. 92.— California; near An-

quarter-inch high: involucre nearly hemispherical, shorter than the disk ; the 12 to 14 ovate

bracts cupulate-connate to the middle: rays and numerous disk-flowers golden yellow, and
quite like those of Lasthenia glabrata. To refer the plant to that genus seems impractica-

maphrodite and fertile. Involucre campanulate, shorter than the disk ; its bracts
imbricated in two or three series, oblong or ovate, appressed ; outermost short
ones nearly herbaceous; inner partly or wholly scarious and obscurely nervose
when dry, a few of the innermost among the outer flowers. Receptacle other-
wise naked, flat. Corolla with short proper tube and elongated upwardly enlar-
ging throat, 5-toothed; the teeth ovate, spreading, hispidulous outside. Style-
branches slender and produced into indistinct subulate hispidulous appendages.
Akenes somewhat turbinate, hirsute, obsoletely 5-nerved and many striate. Pap-
pus of 15 to 20 rigid short-plumose bristles in a single series. — Greene in Bull.
Calif. Acad. i.179. Carphephorus, § Kuhnioides, Gray, p. 113.

B. jancea, Greene, 1.c. Shrubby at base, fastigiately much branched, a yard or less high;

flowering branches rush-like, herbaceous or mainly so, mostly leafless and alternate, bearing
solitary or scattered heads: leaves few or sparse; lower opposite, oblong to linear, the lar-

ger often laciniate and petioled ; upper small and linear, or reduced to subulate minute
scales: flowers golden yellow, sweet-scented (somewhat as in those of Acacia Farnesiana).—
Carphephores junceus, Benth. & p. 113. B. atriplicifolia (Carphephorus atriplicifolius, Gray,
1. ce.) of Lower California is probably the same, and var. aspera, Greene, 1. c., is.a common
hispidulous state. — Rocky places, in cafions, &c. in the arid regions of Arizona and S. EF.
California (Lower Calif., first coll. by Hinds). Evidently an outlying representative of the
subtribe Liubee.

S. atireus, var. Balsamite, p. 391. Add syn.: S. ceratophyllus, Nees, Pl. Neuwied
Mravenlo!

S. Neo-Mexicadnus, Gray, p. 392. S. Austine, Greene, Bull. Calif. Acad. i. 93, is
probably a form of this, from the northeastern borders of California, in Modoe Co., Ars.
Austin. ,

S. Lyoni. (Next after S. eremophilus, p. 393.) Obscurely suffrutescent, and somewhat
succulent, early glabrate except the persistent dense tufts of wool in the axils: leaves once
or twice prinnately parted into linear obtuse segments and lobes, glabrous above, minutely
woolly-pubescent beneath: peduncle bearing a few pedicellate heads (these 4 to 6 lines
high and radiate): pedicels and involucre sparingly subulate-bracteolate. — Island of San
Clemente, off S. California, on cliffs by the sea, Nevin & Lyon, April, 1885.

S. Californicus, DC. Growing in sand along the sea-shore (San Diego and southward) it
becomes succulent and dwarf, when it is S. ammophilus, Greene, Bull. Calif. Acad. i. 198.

At the end of the genus, p. 394, add : —
* %* + * Tndigenous winter-annual: heads with few and minute ray-flowers, or none.

S. Mohavénsis. Glabrous, branching from the base, leafy up to the loose corymbiform
panicle: leaves soft and thickish, ovate or oblong, sinuate-dentate or sparingly incised, cau-
line with auriculate or cordate-clasping base: heads slender-peduncled, 4 lines high : involucre
narrow-campanulate, 18-20-flowered ; calyculate bracts few and inconspicuous: ray-flowers
when present mostly difformed and biligulate, not surpassing the disk: akenes canescent. —
S. E. California in the Mohave region, near the Colorado, Lemmon. (Also within the bor-
ders of Sonora, Mex., Pringle.)

213. STEPHANOMERIA, Nutt.

S. coronaria, Greene, Bull. Calif. Acad. i. 194, Santa Lucia Mountains, Brandegee, by the
character seems too like S. exigua, Nutt , p. 414.

219. MICROSERIS, § Scorzonetta. At end, p. 418, add: —

M. Howéllii, Gray. A foot or more high from a fusiform root, slender, bearing solitary
or 2 or 3 heads: leaves (only 2 or 3 lines wide) elongated-linear and attenuate, some bearing
a few attenuate refracted lobes; involucre half-inch high, narrow, 15-20-flowered ; its bracts
all acuminate ; inner oblong-lanceolate and all nearly equal; outer much shorter and mostly
ovate: akenes 3 lines long, narrower at base : pappus of 8 or 10 conspicuous and firm lance-
olate pale, which nearly equal the length of the akene and bear a denticulate-scabrous awn
of hardly greater length !— Proc. Am. Acad. xx. 300, where by some mistake the pappus
is quite wrongly described. — Waldo, S. W. Oregon, June, 1884, Howell. Ambiguous be-
tween the sections Scorzonella and Calais, with pappus-palex of the latter, except in number,
but perennial or biennial from a fusiform root, and the habit of a slender M. leptosepala.

tifid, the lobes almost linear: involucre well imbricated, less than half-inch high ; outermost
bracts ovate, innermost linear, all scarious with green or purplish tip and centre: corolla
yellow: receptacle almost destitute of bristles: akenes 15-ribbed, five of the ribs angulate-
prominent : one or two stronger pappus-bristles persistent. — Bull. Calif. Acad. i. 194. —
S. California, on Coronados Islands, off San Diego, Greene.

M. folidsa. Between M. obtusa and M. incana, p. 423, with habit of M. saratilis, but an an-
nual, with much smaller heads of yellow flowers, glabrous: stem a foot or two high, erect,
much branched, very leafy even to the branchlets: leaves lanceolate, most of them laciniate-
pinnatifid, 2 to 4 inches long, uppermost linear-attenuate : heads short-peduncled, 3 to 5 lines
high: bracts of the involnare lanceolate, rather obtuse: akenes somewhat equally 10-costate :
pappus wholly deciduous, leaving neither bristles nor crown. — Island of San Clemente, off
Southern California, Nevin & Lyon, April, 1885.— Connects the Leucoseris of Nuttall with
his Leptoseris.

M. saxatilis, Torr. & Gray, p. 423. Under this may be more than one species, not only
the MW. tenwifolia, Torr. & Gray, but also a larger-flowered one, MM. altissima, Greene, Bull.
Calif. Acad. 1. ¢., of mountains of Kern Co., Mrs. Layne-Curran, said to be annual (but not

PB Ree EAC Eh:

Tus volume commences where the Flora of North America by Torrey
and Gray stopped, thirty-five years ago, namely at the close of the great
order of Composite; and the present part comprises the remaining
Gamopetale. It is intended to complete this Synoptical Flora in two
volumes, of about 1200 pages each; the first to cover the ground which
was gone over in the work referred to (now wholly out of print as well
as antiquated), that is, to contain the orders from Ranunculacew to Com-
posite, newly elaborated. The next ensuing part of the present volume
will be devoted to the Apetale and Gymnosperme, and the final portion
to the Monocotyledones and the Vascular Cryptogamia.

Botanists will need no particular explanation of the plan of this work.
Geographically it comprises the United States and all the North Amer-
ican continent and islands northward, Greenland excluded. The series
of Natural Orders adopted is that of Bentham and Hooker’s Genera
Plantarum. The generic characters are given synoptically, but with
essential completeness, at the beginning of each order. The characters
of sections of genera, when of comparatively high rank, are designated by
the sectional mark (§) and printed in the larger type; and those of
first importance, such as may be termed subgenera, are distinguished by
haying a substantive name. Subsections, and also primary divisions
when of low rank, are in small type. Such subdivisions are very freely
made, for convenience of analysis and to save repetition of identical
phrases under the included species ; and they are preferred to artificial
keys to the species, because enabling these to be grouped more naturally.
If somewhat less facile for rapid determination, they are more ex-

haustive and less liable to mislead ; and they permit the ultimate specific

vl PREFACE.

characters to be more simply diagnostic. In monotypic genera, it has
been found more convenient to give the details under the species, in.
the form of a specific character. Throughout the work, from the order
down to the species or variety, the endeavor is to avoid repetition of
statement. ;

The names of introduced species, sufficiently established to claim a
place in our flora, are printed in small capitals, as are such adventitious
or extraneous species as require mention.

In the accentuation of generic, sectional, and specific names, no
attempt is made (as in the Manual of Botany of the Northern United
States and other works) to mark the quality of the accented vowel, but
only to designate the syllable upon which the principal accent falls.

Compactness being essential, only the leading synonymy and most
important references are given, and these briefly. All deficiency in this
respect will be amply supplied by the Bibliographical Index to North
American Botany, prepared at the Harvard University Herbarium
by Sereno Watson, and now in course of publication by the Smith-
sonian Institution. The first part of this most important adjunct to the
present work, which is just issued, gives the full bibliography of the
Polypetale (the subject of the first volume of Torrey and Gray’s Flora
of North America, published in 1858 and 1840), with revision, critical
corrections, and additions up to the present time. Its continuation may

be expected to proceed part passu with this Flora.

HARVARD UNIVERSITY HERBARIUM,
Cambridge, Massachusetts, April 10, 1878.

In this edition many corrections have been made upon the electro-
type plates; but larger ones are given in the Supplement, along with
additions of new material and the re-elaboration of old. Page 68 and
pages 389-392 have been reconstructed, and a full Index is added.

SYNOPTICAL

FLORA OF NORTH AMERICA.

Division I]. GAMOPETALOUS DICOTYLEDONOUS PLANTS

CONTINUED AFTER COMPOSITA.

ORDER LXXIV. GOODENIACE.

Sarussy or herbaceous plants, chiefly with alternate leaves and no proper
stipules, most resembling Lobeliacee, especially in having the corolla cleft down
between two of the lobes more deeply than between the rest; but without
milky juice, the anthers separate, and a cup-like indusium around and at first
enclosing the stigma. Mainly Australian and Oceanic, one or two species of
the following genus reaching or overpassing the northern tropic.

1. SCASVOLA, L. (Diminutive of sceva, a left-handed person; application
obscure.) Calyx adnate to the 2-celled ovary; the limb 5-cleft or a mere border
around the base of the epigynous 5-lobed corolla, the tube of which is cleft down
one side to the base; its lobes valvate-induplicate in the bud. Stamens 5,
epigynous, or lightly connected with the base of the corolla, alternate with its
lobes, distinct. Ovules solitary or a pair in each cell, erect. Fruit drupe-like,
or when dry nut-like. Flowers in axillary cymes, or sometimes solitary. —
L. Mant. 145; Benth. & Hook. Gen. ii. 539.

S. Plumiéri, Vahl. Lowand shrubby, with fleshy obovate entire leaves, woolly-bearded in
the axils, otherwise smooth: limb of the calyx a truncate border: corolla white, an
inch long; the tube as long as the lobes, very woolly inside. — Lobelia, Plum. Ic. t. 165;
Catesb. Car. i. t. 79.— Seashore, S. Florida. (W. Ind., S. Afr., S. Asia.)

OrpER LXXV. LOBELIACEZ.

Herbs (out of the tropics), the juice usually milky and acrid, with alternate
simple leaves, no stipules, racemose inflorescence, and perfect 5-merous flowers ;
having the calyx-tube adnate to the ovary, epigynous irregular corolla and sta-
mens, the latter as many as the lobes of the corolla and alternate with them, and

2 LOBELIACEZ. Nemacladus.

usually both syngenesious and monadelphous. Limb of the calyx divided down to
the ovary, which is wholly inferior or sometimes a large part free ; its lobes generally
persistent. Corolla (with the stamens) inserted just where the calyx becomes
free from the ovary, its lobes mostly valvate or induplicate in the bud, commonly
deeper cleft or completely split down between two of the lobes, the cleft mostly on
the upper side (next the axis of inflorescence) in the open blossom, but becoming
so by a twist; in the early bud the cleft looks toward the bract. The 5 petals
occasionally disposed to separate from below upward, and the limb to be bilabiately
irregular. Filaments generally free from the corolla, sometimes more or less ad-
herent to its tube : anthers 2-celled, introrsely dehiscent, firmly united around the top
of the style into a ring or short tube (except in an anomalous tribe). Ovary
2-celled with placente projecting from the axis, or sometimes 1-celled with 2
parietal placentae. Style entire: stigma commonly 2-lobed, girt with a rim of
hairs. Ovules and seeds mostly indefinitely numerous, small, anatropous. Embryo
small or narrow, straight, in the axis of fleshy albumen. (Too near the Cam-
panulacee, and nearly passing into them, therefore united by recent authors ; but
as there are two dozen genera, agreeing in the indefinite inflorescence, irregular
corolla, and mostly in the syngenesious anthers, it seems best to retain the order.)
Trine I. CYPHIE. Anthers entirely separate, merely surrounding the stigma.

1. NEMACLADUS. Calyx partly or wholly free. Corolla bilabiately irregular; lower
lip 3-, upper 2-lobed or parted. Filaments monadelphous above the middle: anthers oval,
glabrous. Style incurved at tip: stigma capitate, 2-lobed, obsoletely annulate. Capsule
2-celled, 2-valved from top, 20-40-seeded.

Tribe Il. LOBELIE. Antherssyngenesious. Corolla truly gamopetalous, at least

above, in ours distinctly bilabiate, two lobes turned away from the other three.
* Corolla open down to the base on one (the apparently upper) side.

2. LOBELIA. Calyx-tube short. Corolla with tube commonly straight; the lobe each
side of the cleft erect or turned backwards ; the three others larger and somewhat combined
to form the spreading or recurved (apps rently) lower lip. Stamens free from the tube of the
corolla, monadelphous except near the base. C apsule thin-walled, 2-celled, many-seeded,
loculicidally 2-valved at the top or free upper part.

* ¥* Corolla with a closed tube: capsule wholly inferior.

3.PALMERELLA. Calyx-tube turbinate; the lobes slender. Corolla with an elongated
linear and straight tube, not at all dilated at the throat; the short limb abruptly spreading ;
two lobes small, spatulate-linear and recurving ; the three larger obovate or oblong and
slightly united at base. Filaments more or less adnate to the corolla up to near the throat,
then monadelphous and free, or farther adnate on one side only: anthers oblong; the three
larger naked; the two shorter tipped with a tuft of very unequal stout bristles. Stigma,
ovary, and probably capsule as in Lobelia.

4, LAURENTIA. Calyx-tube turbinate or oblong. Corolla with its tube as long as the

limb, which is like that of Lobelia. So are the stamens, pistil, &c. Capsule short,
2-valved at the summit.

5. DOWNINGIA. Calyx-tube very long, stalk-like. Corolla with a very short tube, and an
ample bilabiate limb; lips spreading, the larger 3-lobed and broad; the two distinct divi-
sions of the smaller narrower. Anther-tube incurved: one or both of the shorter an-
cee tipped with a stout bristle-like point; the others naked. Ovary at first two-celled.

copes very long and linear, crowned with the foliaceous and linear calyx-lobes, terete
or 2-3-angled, e: rly becoming 1-celled with 2 parietal and many-seeded filiform placente,
remaining closed at the narrow apex, dehiscent longitudinally by from one to three long
fissures or valves.

1. NEMACLADUS, Wutt. (Nijua,a thread, and xiadoy, branch, from the
very slender stem and branches.)— Two small annuals a span high, at length
excessively branched and diffuse: leaves minute; the radical obovate ; cauline
reduced to subulate bracts: pedicels capillary, racemose on zigzag branches:
corolla flesh-color.— Gray in Jour. Linn. Soe. xiv. 28.

Lobelia. LOBELIACEX. 3

N. ramosissimus, Nutt. Glabrous, except the minutely pubescent tuft of radical
leaves: calyx 5-cleft; its tube turbinate, adnate to the lower third of the ovary and round-
ish capsule, which does not exceed the rather unequal lobes: corolla short (a line long),
soon separating into 3 or 5 parts or petals: filaments monadelphous above: seeds oblong-
oval. — Pl. Gamb. (Trans. Am. Phil. Soc. n. ser. viii.), 254; Torr. Mex. Bound. 108, t. 55. —
Gravelly or sandy soil, California to New Mexico.

N. longifi6rus, Gray. Radical leaves more canescent: calyx 5-parted, free from and
much shorter than the narrow oblong capsule, its lobes equal: corolla narrower, firmly
gamopetalous, fully 3 lines long, 3 or 4 times longer than the calyx : filaments long-mona-
delphous : seeds short-oval. — Proc. Am. Acad. xii. 60.— 8. California, Wallace, Lemmon.

2. LOBELIA, L. (Commemorates Matthias de U Obel, latinized Lobelius, an
early Flemish herbalist.) — Ours herbs, flowering in summer, some of them showy ;
common in the Atlantic, almost absent from the Pacific. United States. Tube
of the corolla more or less disposed to split up in age into three pieces or into
its five petals; at least the two shorter anthers with a bearded tuft at tip.

§ 1. Homocnuitus, A.DC. Lips of the corolla somewhat equal; one of them
3-toothed, the other 2-parted: flowers long-peduncled from the axil of leaves
or large leafy bracts, in ours red and yellow: perennials.

L. laxifl6ra, HBEK., var. angustifGlia. Tall and branching: leaves lanceolate or
even linear, 3 or 4 inches long, denticulate: peduncles 2 to 4 inches and corolla an inch
long: calyx-lobes hardly longer than the tube. — ZL. persicefolia, HBK., not Lam. ZL.
Cavanillesii, Mart.; Hook. Bot. Mag. t. 3600.— Damp ground, just below the Mexican
border of Arizona, north of Arispe, Thurber. (Mex.) A form intermediate in the breadth
of the leaves between the var. and the Z. Cavanillesii, Cav. Ic. t. 518, or the plant culti-
vated as Siphocampylus bicolor. Anthers sometimes long-hirsute externally, sometimes
nearly naked.

§ 2. Evioperia. (ulobelia, Hemipogon, & Holopogon, Benth..& Hook.)
Larger lip of the corolla 3-parted or 5-cleft and spreading or dependent; the
other two lobes either erect or turned backward: flowers racemose or spicate.

* Flowers bright red, large and showy, on erect or ascending pedicels in a virgate raceme: larger
anthers naked at tip: perennial from slender offshoots, the flowering plants dying throughout in

OrpDER LXXVI. CAMPANULACES.

Herbs, with bland milky juice, alternate simple leaves, no stipules, and regular
5-merous flowers; the tube of the calyx adnate to the 2—5-celled many-ovuled
ovary; the corolla and 5 stamens (alternate with its lobes) inserted where the
calyx becomes free, or the latter adnate merely to the base of the corolla; fruit a
many-seeded capsule, rarely baccate. Calyx persistent, usually divided down to
the ovary. Corolla valvate, induplicate, or rarely imbricate in the bud. Stamens
mostly distinct: anthers with 2 parallel cells, introrse. Style one, almost always
pubescent or puberulent for some distance below the 2 to 5 introrse stigmas.
Ovules anatropous, on placente projecting from the axis. Seeds small, usually
smooth. Embryo straight in the axis of fleshy albumen. Flowers often showy ;
the corolla commonly blue or in the same species white, and withering rather than
deciduous. In fertilization proterandrous; the anthers opening in the bud, dis-
charging their pollen upon the style, where it accumulates upon the collecting
hairs or pubescence; the stigmas (then firmly conniving) maturing and diverging
much later, receiving only pollen conveyed from flower to flower by insects.

Trine I. SPHENOCLE.®. Corolla imbricated in the bud, bearing the short sta-

OrpER LXXXII. MYRSINEACEZ.

Shrubs or trees, with the floral characters of Primulacee, i.e. stamens of the
number of the petals or corolla-lobes and opposite them, undivided style and
stigma, and a one-celled ovary with a free central placenta, bearing few or
numerous peltate amphitropous ovules. These are generally immersed in the
placenta, and only one usually matures into a seed. This is globose, with a thin

coat, and a copious cartilaginous albumen. The fruit is pea-shaped, usually dry-
drupaceous, never capsular. Leaves simple, mostly alternate, without stipules,
commonly marked with some immersed dots or short lines, containing at first
pellucid but at length dark resinous matter ; these also appearing in the flower,
especially in the corolla. (There are similar dots or lines in Lysimachia, of the
preceding order.) No milky juice. Flowers small and the corolla short, rotate
or campanulate. — A tropical order, sparingly reaching the southern borders of
the United States.

Tripe I. MYRSINEZ. Calyx perfectly free. No staminodia. Ovules usually im-
mersed in the fleshy placenta, only one maturing into a seed which fills the cavity
of the fruit.

5- (rarely 4-6-) parted ; the lobes convolute in the bud, or sometimes one wholly exterior.
Anthers lanceolate-sagittate, pointed; the cells dehiscent from the apex downward.

Trine IT. THEOPHRASTEZ. Calyx perfectly free. Staminodia or sterile sta-
mens in the throat at the sinuses of the corolla. Ovules numerous, not immersed
in the placenta, maturing few or numerous seeds.

ORDER LXXXITI. SAPOTACE A.

Shrubs or trees, with perfect flowers, agreeing with the foregoing order in
having fertile stamens of the same number as the (proper) lobes of the corolla
and opposite them, and inserted on its tube, in the short corolla, undivided style
and stigma; differing in the few-several-celled ovary with solitary anatropous
or amphitropous ovules, and a comparatively large seed with a crustaceous or
bony testa (containing a large straight embryo with or without albumen), with
broad and flat or sometimes fleshy-thickened cotyledons; and the juice in most is
milky. Flowers regular and small, in axillary clusters. Calyx free, of 4 to 7
distinct sepals, which are strongly imbricated. Corolla hypogynous, 4—7-cleft,
and the lobes imbricated in the bud, often with as many or twice as many acces-
sory internal lobes or appendages borne on the throat. Staminodia (answering
to series of stamens) commonly present, alternate with the true corolla-lobes and
sometimes in the form of sterile filaments, or squamiform, or petaloid. Filaments
of fertile stamens subulate or filiform, generally short: anthers oftener extrorse ;
the cells opening longitudinally. Fruit baceate, commonly by abortion 1-celled
and 1-seeded ; when several-seeded, the bony seeds are laterally flattened and dis-
posed in a ring around a thickened axis. Leaves alternate, simple and entire,
pinnately veined, mostly coriaceous: stipules small and caducous or none. Pubes-
cence when present silky or tomentose, composed of malpighiaceous or stellate
hairs. — Tropical or subtropical, except our species of Bumelia. Fleshy fruit
of some edible. Juice of certain trees of the order yields gutta-percha. Seed
albuminous in all ours excepting Bumelia.

* Calyx simple, i.e. of mostly 5 sepals in a single series, but strongly imbricated.
+ No internal appendages to the corolla and no staminodia.

1. CHRYSOPHYLLUM. Corolla bearing 5 stamens, otherwise naked within. Ovary
5-10-celled. Seeds 1 to 10, attached by an elongated hilum.

+ + Staminodia one in each sinus of the corolla, but no other internal appendages or
divisions.
2. SIDEROXYLON. Staminodia more or less unlike and smaller than the lobes of the
corolla. Ovary 2-5-celled. Berry drupe-like, usually 1-seeded.

+ + + Both staminodia and appendages or accessory lobes of the corolla present and
petaloid ; the latter one to each side of the proper corolla-lobes (or these 3-parted),
therefore geminate in the sinuses outside of the staminodia: flowers white: anthers

ORDER LXXXVI. OLEACE.

Trees or shrubs, rarely almost herbaceous, with colorless bland juice, opposite
(rarely alternate) leaves destitute of stipules, perfect or dioecious and regular
flowers (gamopetalous, 2—4-petalous, apetalous, or even achlamydeous) ; with
stamens 2 to 4, mostly 2 and fewer than the parts of the corolla, distinct ; the free

shrubs, noted for their very early yellow blossoms, are peculiar in having numerous ovules.

Syrinca, the Lilac, of the Old World, becomes spontaneous in a few places.

Licustrum VuLcAre, the Privet, used for ornamental hedges, is also occasionally found

wild in the vicinity of towns in the Eastern Atlantic States, and may claim to be a really natu-
ralized plant.

Otea Evropxa, the Olive, has long been planted in the southern part of California.

coat: no albumen. Leaves often alternate !

1. FRAXINUS, Tourn. Asn. (Classical Latin name.) — Trees ; with rather
light tough wood, chiefly opposite and odd-pinnate leaves, and small flowers, in

ORDER LXXXVIII. ASCLEPIADACE.

Characters of Apocynacee as to herbage and general structure of flowers and
fruit ; distinguished by the peculiar aggregation and cohesion of the pollen into
granulose or waxy masses (pollinia), one or sometimes two in each anther-cell,
and connected with the stigma or rather stigmatic disk in pairs or fours by means
of 5 glands or corpuscles, which alternate with the anthers. A%stivation of the
corolla often valvate or nearly so. A corona (crown) of five parts or lobes
usually present between the corolla and the mostly monadelphous stamens, and
adnate either to the one or the other. Hypogynous disk within the stamens
none. Styles distinct upto the common stigmatic mass, or none. Fruit always of
2 follicles, or by abortion of one ovary solitary, several-many-seeded ; the seeds
almost always bearing a long and soft coma at the apex. Radicle superior.
Stems herbaceous or merely shrubby, not rarely twining. Leaves almost always
opposite or whorled, destitute of stipules. Inflorescence terminal, pseudo-axillary,
or sometimes axillary, cymose, often umbelliform. Bracts small or minute. The
tube of monadelphous filaments, commonly named gynostegium (a term which has
been applied also to the anther-portion), we call the column.

Perfptroca Graca, L., a woody climbing plant of the Old World, in ornamental culti-
vation, and in one or two places inclined to be spontaneous, represents the tribe or suborder
Periplocee, with granulose pollen loosely aggregated in two masses in each anther-cell. All

the American genera have a single firm-waxy pollen-mass to each anther-cell, i.e. they
belong to the suborder AscLEPIADES.

Trise I. CYNANCHEZ. Anthers tipped: with an inflexed or sometimes erect
scarious membrane ; the polliniferous cells lower than the top of the stigma : pol-
linia suspended, attached in pairs (one of each adjacent cell of different anthers) to
the corpuscle or gland.

* Crown (corona) or appendages to the corolla or andreecium none.

1. ASTEPHANUS. Calyx destitute of glands. Corolla urceolate or short-campanulate,
5-cleft ; the lobes slightly and dextrorsely convolute : stamens inserted on the base of its
tube. Top of the stigma obtusely conical or more elevated. Follicles smooth.

* * Crown double; the exterior annular, interior of 5 flat fleshy or hood-like scales or
processes.

2. PHILIBERTIA. Calyx minutely 5-glandular within. Corolla open-campanulate or
(in all ours) rotate; the lobes dextrorsely convolute, narrowly overlapping. Exterior
crown a membranaceous ring adnate to the base of the corolla; interior of 5 scales adnate
to the base of the usually very short stamen-tube or column. ‘Top of stigma flat or um-
bonate, or with a short 2-cleft beak. Follicles rather thick, smooth, acuminate.

topped: crown consisting of distinct cucullate or hollowed nectarifcrous appendages
(cuculli or hoods), one opposite each anther: anthers margined with mostly corneous and
salient wings.

the lobes erect, oblong, obtuse. Hoods of the crown short, somewhat incurved, and the
margins involute, forming pitcher-shaped nectariferous bodies. Column (and enclosed
styles) slender, almost as long as the corolla: five small processes under and alternating
with the short anthers. Wings of the latter widening downward to the truncate acute-
angled base. Follicles linear-fusiform, unarmed.

gin widening to and rounded at the summit, there enclosing a narrower and pointless
lamelliform crest. Anthers of membranous texture throughout ; their papery (instead
of corneous) wings much broadened downward and horizontally truncate at base. Cau-
dicles almost capillary, more than double the length of the oblong pollinia! Leaves
opposite.

5. ASCLEPIODORA. Corolla rotate-spreading in anthesis. Hoods basilar, inserted over
the whole very short column, spreading and arcuate-assurgent, little surpassing the an-
thers, slipper-shaped and the rounded apex fornicate, hollow and with a thickish fleshy
back, traversed (at least the upper part) by a salient crest which near the apex divides
the cavity. Anther-wings (corneous) narrowed at base, angulate above the middle if at
all. Caudieles shorter than the pyriform pollinia. Leaves commonly alternate.

6. ASCLEPIAS. Corolla almost always reflexed in anthesis. Hoods involute or com-
-plicate, not fornicate, bearing a horn or crest-like (pointed or rarely pointless) process

column which is shorter than the anthers. Corneous anther-wings widening down to the
base, usually triangular, the salient base being truncate or semihastate, or not rarely
broadly rounded. Leaves opposite, sometimes varying to alternate or verticillate.

= = Hoods wholly destitute of crest or appendage within: corolla reflexed in anthesis.

7. ACERATES. Hoods involute-concave or somewhat pitcher-shaped. Anther-wings
widened or angulate if at all near or above the middle, thence narrowed to the base.

OrpER XC. GENTIANACEA.

Herbs, with bitter colorless juice, and (the Menyanthee excepted) with opposite
or rarely verticillate simple and entire sessile leaves, no stipules, perfect and reg-
ular flowers, persistent calyx and often marcescent corolla, the latter (with one or
two exceptions) dextrorsely convolute in the bud, a one-celled tree ovary with
two parietal many-ovuled placenta, or the whole parietes ovuliferous, a single style
with usually 2-lobed or 2-lamellate stigma, and the capsule dehiscent through the
placenta. Seeds indefinitely numerous, or rarely few, anatropous, commonly
small, and with a minute embryo in fleshy albumen. Stamens, as in all the
related orders, borne on the tube or base of the corolla, as many as its lobes and
alternate with them: anthers in our genera 2-celled and opening longitudinally.
Style rarely cleft, at least the divisions stigmatose down the inuer face of the
lobes. Plants almost all glabrous and smooth throughout, and the flowers cymose
or simply terminal. Ovary in all our genera one-celled, or half two-celled by
introflexion of the placentw (in some exotic genera 2-celled). The Menyanthee
differ almost ordinally in the foliage and estivation. Obolaria and Bartonia are
remarkable for the imbricated estivation of the corolla: the sepals of the latter
are reduced to two: their lower leaves or scales are oiten alternate.

Orper XCI. POLEMONIACES.

Herbaceous or rarely shrubby plants, with bland colorless juice, simple or di-
vided leaves and no stipules, perfect and regular 5-merous flowers except that
the free ovary is trimerous (3-celled with placente in the axis) ; the persistent
calyx imbricated, and the corolla dextrorsely convolute (and not plicate) in the
bud; the fruit a 3-celled loculicidal capsule, usually with a thick placental axis ;
the few or many seeds small, amphitropous or nearly anatropous, with a thin or
soft coat, commonly developing mucilage when wetted; the embryo straight and
rather large in the axis of a fleshy or harder albumen, the cotyledons flat or
flattish and rather broad. Stamens on the corolla alternate with its lobes, distinct.

Phlox. POLEMONIACEZ. 129

Style one, 3-lobed or cleft; the introrse stigmas (or lobes of the style stigmatic
down the inner face) slender. Hypogynous disk generally manizest. Almost
exclusively American, and remarkable among the hypogynous gamopetalous
orders for the 3-merous pistil, but in 2 or 3 species of Gilia 2-merous. ‘The corolla
is not always perfectly regular, and the 5 stamens are very commonly unequal in
length or insertion. Cobea, common in cultivation, is very exceptional in the
order, climbing by tendrils belonging to pinnate leaves, and its capsule septicidal.
— Gray, Proc. Am. Acad. viii. 247; Benth. & Hook. Gen. ii. 820.
* Stamens unequally inserted on the tube of the corolla, not declined.

which the unequally inserted filaments commonly protrude. Ovules solitary or numerous.
Seed-coat developing mucilage and projecting uncoiling spiral threads (spiricles) when
wetted, except in one species. Leaves mostly alternate, and pinnately incised or divided.

* * Stamens equally inserted in or below the throat or sinuses of the corolla.

8. LCESELIA. Corolla tubular or funnelform, somewhat irregular, the limb being more
or less unequally cleft; the naked filaments declined. Otherwise as Gilia.

not declined, naked (rarely pubescent) at base. Ovules and seeds from solitary to numer-
ous. Leaves various.

5. POLEMONIUM. Corolla from funnelform to nearly rotate, regular. Filaments more
or less declined and usually pilose-appendaged at base, slender. Ovules and seeds few or
several in each cell. Calyx herbaceous, not scarious below the sinuses nor the lobes cos-
tate, accrescent. Leaves all alternate, pinnate or pinnaicly parted.

1. PHLOX, L. (Ancient Greek name of Lychnis, from gio§, flame.) —N.

American herbs, or a few suiffrutescent, chiefly perennials, many cultivated for

BORRAGINACE. LT

OrpDER XCIII. BORRAGINACE.

Mostly scabrous or hispid-hairy plants, with watery juice, entire and alternate
(or partly opposite) leaves, no stipules, prevalently scorpioid inflorescence, and
regular flowers (in Hehium the corolla, &e., irregular), the 5 or sometimes 4
stamens on the tube or throat of the corolla, as many as and alternate with its
lobes, a single style rising between the divisions of a deeply 4-parted ovary, or
from the summit of an undivided one, the cells or lobes of which contain a solitary
ovule, the seed with little or no albumen, the embryo straight or rarely curved,
its radicle superior or centripetal. Flowers perfect, generally 5-merous. Calyx
and corolla free; the lobes of the latter imbricated, convolute, or sometimes plicate
or induplicate in the bud. Uypogynous disk usually present, but inconspicuous.
Pistil of 2 biovulate carpels, although seemingly of 4 and uniovulate. Ovule
anatropous or amphitropous. Fruit of 4 nutlets (or by abortion fewer), or a
drupe containing 2 to 4 nutlets or cells, rarely reduced to one. — Some of the
first great division have serrate and even incised leaves, and are trees or shrubs,
of tropical or subtropical regions: these well distinguished from related orders
by the superior radicle. The true Borraginacee are almost all herbs, mainly of
temperate climates, with undivided style and even stigma, surrounded at base by
the four distinct divisions of the ovary. Inflorescence and its nomenclature as
in the preceding order.

I. Ovary undivided (or only laterally 4-lobed) and surmounted by the style.

Trise I. CORDIEA. Style twice bifid: stigmas terminal, not annular. Fruit
drupaceous. Cotyledons longitudinally plicate or corrugated. Trees or shrubs,
with leaves sometimes dentate.

1. CORDIA. Calyx tubular or campanulate, merely toothed or lobed. Corolla funnel-
form or salverform; the lobes and stamens sometimes more than 5. Stigmas clavate or

capitate. Ovary and drupe 4-celled, 4-seeded, or fewer by the abortion of some of the
cells and seeds of the hard stone.

Trise If. EMRETIE. Style once bifid or 2-parted (the divisions sometimes
coalescent to the top): stigmas more or less capitate. Cotyledons plane. Trees,
shrubs, or low herbs.

* Fruit drupaceous: ovules mostly amphitropous : trees or shrubs.

2. BOURRERIA. Calyx globular or ovoid, closed in the bud, valvately splitting at the
summit into 2 to 5 teeth. Corolla campanulate or short-funnelform. Drupe containing
4 more or less separable one-seeded nutlets.

3. EHRETIA. Calyx 5-parted or 5-cleft, imbricated or open in the bud. Corolla from
short-funnelform to rotate. Drupe usually containing 2 two-celled two-seeded nutlets.

* * Fruit dry: ovules anatropous, pendulous: herbaceous or suffruticulose plants.

4, COLDENIA. Calyx 5-parted, or in original species 4-parted; the divisions narrow.
Corolla short-funnelform or nearly salverform, seldom much surpassing the calyx; the
lobes rounded, imbricated or sometimes partly convolute in the bud. Stamens included.
Style 2-cleft or 2-parted. Ovary entire or laterally 4-lobed, 4-celled. Fruit separating at
maturity into 4 one-seeded nutlets, or by abortion fewer, or in one species by suppression
one-celled and one-seeded. Cotyledons thickish. Albumen none.

Trise III. HELIOTROPIEZ. Style entire, sometimes wanting : stigma peltate-
annular, forming a complete ring, surmounted usually by an entire or 2-lobed (from
hemispherical to subulate) tip or appendage. Ovules pendulous. Seeds with a
straight or incurved embryo, in sparing or copious albumen. Leaves entire, rarely
denticulate. Inflorescence more or less scorpioid.

herbaceous. Otherwise nearly as //eliotropium.

HELIOTROPIUM. Calyx deeply 5-parted, persistent. Corolla salverform or funnel-
form, plaited and mostly imbricated in the bud. Stamens included: filaments short or
none: anthers connivent, sometimes cohering by pointed tips. Ovary 4-celled, 4-ovuled.
Fruit dry, 2- or 4-lobed, separating into 2 indurated 2-celled and 2-seeded closed carpels, or
more commonly into 4 one-seeded nutlets. Seed sometimes with rather copious albumen,
and, with the embryo, curved. — Low herbs or undershrubs; the flowers almost always
small.

II. Ovary 4-parted (rarely 2-parted) from above into one-celled one-ovuled

divisions surrounding the base of the undivided (rarely 2-lobed) style: stigma
not annular, terminal.

Trise IV. BORRAGEX. Style entire, in Lchium 2-cleft at the apex: stigma trun-

ites

cate or depressed-capitate, in a few species of Lithospermum tipped with a rudi-
mentary terminal appendage. Ovules amphitropous or almost orthotropous and
commonly ascending or erect, or when anatropous mostly pendulous. Nutlets 4
(or by abortion fewer), distinct, or sometimes at base united in pairs. Radicle
superior or centripetal. Albumen none. Chiefly herbs, with somewhat mucilagi-
nous watery juice and entire leaves. Flowers mostly near, but not in the axil of
leaves or bracts, or bractless in scorpioid so-called spikes or racemes. /Estivation of
the corolla imbricated, except when otherwise indicated. (The depressed or elevated
disk, receptacle, or axis on which the nutlets are inserted, and from which they fall
away, is called the gynobase.)

* Corolla and stamens regular: style entire, or sometimes barely 2-cleft at the very apex.

+— Ovary only 2-parted: fruit involved in a bur-like transformed portion of the calyx.

HARPAGONELLA. Calyx at first slightly but in fruit exceedingly unequal; three
of the lobes nearly distinct; the remaining two more united, closely enwrapping the fruit,

BorrAGO OFFICINALIS, L. (BoRAGE), with very rotate blue corolla, is a not uncommon
annual in country gardens, but does not run wild. OmpHaLopes cinrroLi1a, Meench, of
S. Europe, is given in Hooker’s Flora Boreali-Americana, on the strength of a specimen re-
ceived from Newfoundland, to which it cannot be native, and the plant is rare in gardens,
in which O. verNA is a hardy perennial, but it does not escape.

other half. Both carpels uniovulate and alike in flower, and both, according to Bentham,
are sometimes fertile and enclosed together in the calyx. Sometimes one is excluded and
naked, but falls away without maturing.

The specific names conferred by Michaux on this and the preceding species were replaced
in the Prodromus by earlier ones under Lithospermum ; which may be agreed to, Michaux’s
O. hispidum being far less hispid than O. Carolinianum, and O. molle is a misnomer except for
the western variety (which cannot be separated) on which Michaux’s species is founded.

but the apex, or plumule, often bearing a few alternate scales, germinating in the
soil, but not rooting in it, developing into filiform and branching annual stems
of a yellowish or reddish hue, which twine dextrorsely upon herbs or shrubs,
and become parasitic by means of suckers which penetrate the bark in contact,
the base soon dying away. Small scales of the same color as the stem take
the place of leaves and bracts. — Choisy in Mem. Genev. 1841 (cited “ Cuse.”) &

Engelm. l.c. C. remotiflora & C. fruticum, Bertol, Mise. x. 29. — Canada to Alabama along
and west of the Alleghany Mountains, west to Missouri and Texas, in damp woods, almost
always on shrubs. The original C. compacta of Jussieu’s herbarium is a slender form, with
smaller flowers and more exserted corolla: it is found from N. New York southward along
the Alleghanies. The var. adpressa, Engelm. Cuse. 511 (Lepidanche adpressa, Engelm. in

positarum, Engelm. in Am. Jour. Sci. xliii. 344, fig. 30-35. — Wet prairies, Ohio to Wisconsin,
Kansas and Texas, mostly on Helianthus, Vernonia, and other tall Composite. The rope-like
twists, half to three-fourths inch thick, of white flowers with golden yellow anthers im-
bedded in a mass of curly bracts, have a singular appearance and justify Rafinesque’s
name, which probably belongs here.

* * (EuvGrammica, Engelm. Cuse. 476.) Capsule more or less regularly cireumscissile, usually
capped by the remains of the corolla: styles capillary and mostly much longer than the depressed

short pedicels in large clusters: lobes of the campanulate calyx and of the tubular corolla
ovate, acute, rather shorter than the cylindrical tube: scales hardly reaching to the base
of the anthers, incisely dentate toward their rounded apex. — Cusc. 486.— Arizona,
Wright, on Amaranthus. A large-flowered species, distinguished from the large-flowered
Mexican forms of C. corymbosa by its acute lobes of calyx and corolla.

length) clustered on short pedicels: rounded lobes of calyx and corolla thin in texture, as
long as the wide and shallow tube: scales deeply fringed, often exceeding the tube : styles

Coarse stems climbing high: flowers (a line or two long) very abundant, on short pedicels in
globose clusters: calyx globular-cupulate, almost enclosing the corolla; the lobes of which
are much shorter than the slender tube: anthers globular and almost sessile: scales short,
more or less dentate: seed usually solitary. This S. American and West Indian species,
easily known by its proportionally large calyx and small corolla, is here characterized be-
cause it may be looked for in South Florida.

§ 2. MonoGyN&LLa, Engelm.1.c. Styles united into one: stigmas capitate :
capsule circumscissile. — Monogynella, Desmoulins. (Consists of few species, of
the largest size, mostly Asiatic, extending to Europe, 8. Africa and N. America.)

C. exaltata, Engelm. Stems thick, climbing high : lobes of the fleshy calyx and corolla
orbicular, the former covering and the latter half the length of the corolla-tube: anthers

ORDER XCV. SOLANACE.

Herbs, shrubs, or even trees, commonly rank-scented, with watery juice, alternate
leaves and no stipules; the inflorescence properly terminal and cymose, but
variously modified, sometimes scorpioid-racemiform in the manner of Borraginacee
and Hydrophyllacee, the pedicels either not accompanied by bracts or not in their
axils; flowers perfect and regular (or only slightly irregular) and 5—4-merous ;
the stamens as many as and alternate with the corolla-lobes; these induplicate-
valvate or plicate (rarely merely imbricate) in the bud; ovary wholly free, nor-
mally 2-celled with indefinitely many-ovuled axile placenta, and surmounted by
an undivided style: stigma entire or sometimes bilamellar; ovules anatropous or
amphitropous ; fruit either capsular or baccate ; embryo terete and incurved or
coiled, or sometimes almost straight, in fleshy albumen, the cotyledons rarely
much broader than the radicle. ‘The leaves, although never truly opposite, are
often unequally geminate, so as to appear so. Obviously distinguished from Con-
volvulacee by the greater number and the character of the seeds, Jess definitely so
from Serophulariacee by the regular flowers with isomerous stamens and plicate
or valvate zstivation of the corolla, and centrifugal inflorescence, but in the last
tribe nearly confluent with that order by the imperfection or abortion of one or
three of the stamens, and some obliquity and bilabiate imbrication of the limb or
lobes of the corolla. Micandra has a regularly 3—5-celled ovary ; that of Lycoper-
sicum, &c., becomes several-celled in cultivation; that of Datura is spuriously
4-celled.

Bassovia? HEBEPODA, Dunal in DC. Prodr. xiii. 407, characterized from a specimen com-
municated to De Candolle by Teinturier of New Orleans, in fruit only, is a mere riddle. It is
said to resemble Bassovia lucida.

Wirnanta Morisont, Dunal, 1. ¢., is doubtless not a Virginian or even a Mexican plant.
From the figure it is likely to have been W. somnifera, as Dunal suggested.

Tripe I. SOLANE. Corolla (mostly short) with the regular limb plicate or val-
vate in the bud, usually both, i.e. the sinuses or what answers to them plicate and the
edges of the lobes induplicate. Stamens (normally 5) all perfect. Fruit baecate
or at least indehiscent, sometimes nearly dry. Seeds flattened: embryo curved or
coiled, slender ; the semiterete cotyledons not broader than the radicle.

¥ Anthers longer than their filaments, either connivent or connate into a cone or cylinder:
corolla rotate: calyx mostly unchanged in fruit: parts of the flower 5 or varying to
more, especially in cultivation.

1. LYCOPERSICUM. Anthers connate into a pointed cone, tipped with an empty closed
acumination; the cells dehiscent longitudinally down the inner face. Otherwise as in the
next, but leaves always pinnately compound.

2. SOLANUM. Anthers connivent or lightly connate: the cells opening at the apex by a
pore or short slit, and sometimes also longitudinally dehiscent even to the base; the con-
nective inconspicuous or obsolete.

* * Anthers unconnected, mostly shorter than their filaments, destitute of terminal pores,
dehiscent longitudinally.
+ Calyx not investing the fruit, nor much changing under it.

3. CAPSICUM. Calyx short, either truncate or merely 5-6-dentate. Corolla rotate,
deeply 5-6-cleft, valvate in the bud, not plicate. Anthers oblong or somewhat cordate.
Berry, or juiceless and thin-coriaceous pericarp, acrid-pungent, girt only at base by the
nearly unchanged calyx.

the bud. Stamens inserted high on the tube of the corolla! Berry globular or oblong.

5. ORYCTES. Calyx deeply 5-cleft; the lobes narrow, herbaceous. Corolla short-tubu-
lar or oblong, 5-toothed; the triangular lobes plicate in the bud, apparently erect. Sta-
mens inserted on the base of the corolla, included: filaments filiform, unequal: anthers
didymous. Berry apparently dry, globose, 10-20-seeded. Embryo apparently of this
tribe, but not seen mature.

+ + Calyx herbaceous and closely investing the fruit or most of it, not angled.

6. CHAMZSARACHA. Corolla rotate, 5-angulate, plicate in the bud. Filaments fili-
form: anthers oblong. Berry globose, filling the investing calyx, and its summit usually
more or less naked. Pedicels solitary in the axils, refracted or recurved in fruit.

+ + + Calyx becoming much enlarged and membranaceous-inflated, enclosing the
fruit, reticulate-veiny,
++ Five-toothed or lobed, vesicular in fruit: ovary 2-celled.

7. PHYSALIS. Corolla rotate or rotate-campanulate, plicate in the bud, 5-angulate or
obscurely 5-lobed. Stamens not connivent. Calyx in fruit 5-angled or 10-costate, and
the teeth or short lobes connivent, completely and loosely enclosing the juicy berry.
Pedicels solitary.

8. MARGARANTHUS. Corolla urceolate-globose and 5-angular-gibbous above a short
narrow base, and with minutely 5-toothed contracted orifice, including the connivent
stamens. Otherwise as Physalis.

++ ++ Five-parted calyx connivent-vesicular in fruit: ovary 5-5-celled.

9. NICANDRA. Corolla open-campanulate, with entire or obscurely lobed border,
strongly plicate in the bud. Filaments filiform, included, dilated into a pubescent scale
at base. Calyx strongly 5-angled; the scarious-membranaceous and reticulated divisions
cordate-sagittate, the deflexed auricles at the sinuses acuminate. Fruit globose, dry or
nearly so at maturity. Pedicels solitary, recurved.

Trise Il, ATROPEZE. Corolla with the regular limb imbricated in the bud, the
sinuses little or not at all plicate. Stamens (4 or 5) all perfect. Baccate fruit
and seeds as in the preceding.

10. LYCIUM. Calyx campanulate, irregularly 3-5-toothed or cleft, or somewhat truncate,

salverform; the lobes oblong or roundish, plane. Stamens often exserted: filaments
filiform: anthers short. Style filiform: stigma capitate or broadly 2-lobed. Berry
globular or oblong, subtended by the calyx, few-many-seeded, rather dry. Seeds reni-
form or rounded, flattened. Flowers either 5-merous or 4-merous.

Tre IT. HYOSCYAMEE. Corolla with the limb either plicate or imbricated in
the bud. Stamens (5) all perfect. Fruit a capsule. Seeds and embryo as in the
preceding tribes.

11. DATURA. Calyx prismatic or tubular, 5-toothed, in ours at length cireumscissile near
the base, the base remaining as a peltate border under the fruit (rarely splitting length-
wise). Corolla funnelform, with ample spreading border 5-10-toothed, convolute-plicate
in the bud. Stamens included or slightly exserted: filaments long and filiform. Style
long: stigma bilamellar. Capsule muricate or prickly (rarely smooth), commonly firm
and 4-valved from the top, sometimes fleshy and bursting irregularly at the top, 2-celled ;
the large many-seeded placente projecting from the axis into the middle of the cells
and connected with the walls by an imperfect false partition, so that the ovary and fruit
are 4-celled except near the top, and the placente as if borne on the middle of the
abnormal partitions. Seeds large, reniform-orbicular.

12. HYOSCYAMUS. Calyx urceolate or tubular-campanulate with a 5-lobed limb, en-
larged and persistent, becoming many-costate and reticulate-veiny, enclosing the capsule.
Corolla short-funnelform, with an oblique 5-lobed limb, plicate-imbricated in the bud;
the lobes sometimes conspicuously unequal, those of one side being smaller! Stamens
more or less exserted and declined. Style filiform: stigma capitate-dilated. Cap-
sule membranaceous, circumscissile towards the summit, which separates as a lid. Seeds
less flattened.

Tribe IV. CESTRINEZE. Corolla (usually elongated) with the regular limb in-
duplicate-valvate or induplicate-imbricated in the bud. Stamens (mostly 5) all

perfect. Fruit either baccate or capsular. Seeds little or not at all flattened. Em-

bryo either straight or only slightly curved ; the cotyledons usually broader than
the radicle.

13. CESTRUM. Corolla salverform or tubular-funnelform ; the short lobes induplicate-
valvate in the bud. Filaments filiform: anthers short, explanate after dehiscence.
Ovary usually short-stipitate, few-ovuled. Fruit a rather dry globular berry. Seeds
few, or by abortion solitary, with a smooth testa: cotyledons usually broad and flat.

14. NICOTIANA. Corolla funnelform or salverform, plicate and somewhat imbricate in
the bud. Filaments filiform, mostly included: anthers ovate or oblong, often explanate
after dehiscence. Ovary normally 2-celled, with large and thick placentew, bearing very
numerous ovules and seeds. Style filiform: stigma depressed-capitate and often 2-lobed.
Fruit a capsule, more or less invested by the persistent calyx, septicidal and also usually
loculicidal at summit; the valves or teeth thus becoming twice as many as the cells, i.e.
usually 4. Seeds very small, with granulate or rugose-foveolate testa: cotyledons little
broader than the radicle.

Trise V. SALPIGLOSSIDE. Corolla with lobes (either regular or somewhat
irregular) plicate or induplicate and also more or less bilabiately imbricated, the two
superior external. Stamens 5, conspicuously unequal, four being didynamous and
the fifth smaller, the latter (and even one pair of the others) sometimes imperfect
or abortive. Seeds globular or angular, not compressed. Embryo curved or tiearly
straight, with cotyledons usually broader than the radicle. (Transition to Scrophula-
riacee.)

naceous, 2-valved; the valves at length 2-cleft.

1. LYCOPERSICUM, Tourn. Tomato, &e. (Avz0g, wolf, megatxor,
peach.) — Chiefly annuals, natives of the warmer parts of America; with once
or twice pinnate leaves, rounded petiolulate leaflets, racemes (so called) of small
flowers becoming lateral or opposite the leaves, articulated pedicels reflexed in
fruit, and red or yellow pulpy berries, in cultivation esculent and often becoming
several-celled.

L. Escuténtum, Mill., var. cerastrOrme. (CHERRY-Tomato.) Annual, hirsute on the
branches and more or less glandular: leaves interruptedly 1-2-pinnate; the larger leaflets
incised and toothed, the interposed small ones rounder and often entire : calyx little shorter
than the yellow corolla: inflorescence bractless: berry globose and even, small. — L. cerasi-
forme, Dunal. Solanum Lycopersicum, var., L. S. Pseudo-Lycopersicum, Jacq. Vind. t. 11.—

The normal form, probably, of the Tomato of the gardens: spontaneous on the southern
borders of Texas (Berlandier, &c.): introduced from Trop. Amer.

2. SOLANUM, Tourn. Nicursnapr, &c. (Late Latin name of Night-
shade, probably from solamen, solace.) — Herbs or sometimes shrubs, of various
habit; with the leaves (as in many other genera of the order) often geminate,
the proper leaf being accompanied by a smaller lateral or extra-axillary (rameal)

Solanum. SOLANACEZ. Dy

one, and the peduncles also extra-axillary or lateral. Flowers cymose, mostly
atter the scorpioid manner, or by unilateral suppression in appearance racemose,
or rarely solitary, sometimes polygamous through the abortion of the pistil of
many of the flowers. A vast genus, generally diffused over the temperate and
warmer parts of the world, but sparingly represented in North America.

S. VirerniAnum, L. (founded on Dill. Elth. t. 267, and Pluk. Alm. t. 62, fig. 5), is some
one of the very prickly exotic species and not of Virginian origin.

S. mammosum, L., a West Indian species, attributed to Virginia by Linneus and succeed-
ing authors, is unknown in the country. The less hairy S. aculeatissimum may sometimes
have been taken for it. In Chapman’s Flora a form of S. MJelongena seems to represent it.

S. TexAnum, Dunal in DC. Prodr. xiii. 859, is probably not Texan, although raised from
seed said to have been collected there. It is a plant of the Melongena (Aubergine or Egg-
Plant) type, and is probably S. integrifolium, Poir. (S. dthiopicum, Jacq. Vind. t.2, not L.},
and according to Tenore his S. Lobelii. It has a 7-8-cleft calyx, and the fruit (from a solitary
fertile flower) 5-10-celled.

S. FroripAnum, Dunal, 1. c. 306, taken up from an imperfect specimen so named by Shut-
tlewerth in herb. DC., collected by Rugel at St. Mark’s, Florida, is not identified, is prob-
ably some waif of ballast ground, and, having long-hairy and retrorse-prickly stems and
pinnately parted leaves, cannot be a variety of S. Carolinense, to which Chapman referred it.

§ 1. Fruit naked, i.e. not enclosed in the accrescent calyx (in one species
somewhat so): stamens all alike.
* Tuberiferous-perennial, pinnate-leaved: anthers blunt.

S. tuberésum, L. (Poraro-rLant), var. boreale. Low, more or less pubescent : tubers
_about half an inch in diameter, sending off long creeping subterranean stolons: leaflets

5 to 7, ovate or oval, and with only one or two interposed small ores, or sometimes none
at all: peduncle few-flowered: corolla blue or sometimes white, angulate-5-lobed.— 8S.
Fendlert, Gray in Am. Jour. Sci. ser. 2, xxii. 285; Torr. Bot. Mex. Bound. 151.— New
Mexico, especially in the mountains, and southward: apparently not specifically distinct
from the Potato-plant, which extends along the Andes to Chili and Buenos Ayres.

S. Jamésii, Torr. Low, a span or so in height: leaflets 5 to 9, varying from lanceolate
to ovate-oblong, smoothish ; the lowest sometimes much smaller, but no interposed small
ones: peduncle cymosely few-several-flowered: corolla white, at length deeply 5-cleft:
otherwise as in the last. — Ann. Lyc. N. Y. ii. 227; Gray, 1. c.— Mountains of Colorado
to New Mexico and Arizona. (Mexico, probably under several names.) Seems on the
whole distinct ; but Fendler’s no. 669 belongs here, at least in part.

* * Annuals (at least in our climate), simple-leaved, never prickly, but the angles of the stem

sometimes minutely denticulate-asperate: anthers blunt: pubescence when present simple:
flowers and globose berries small.

+ Leaves deeply pinnatifid.

S. triflorum, Nutt. Green, slightly hairy or nearly glabrous, low and much spreading :
leaves oblong and pinnatifid, with wide rounded sinuses; the lobes 7 to 9, lanceolate, 3 or
4 lines long, entire or sometimes 1-2-toothed : peduncles lateral, 1-3-flowered : pedicels nod-
ding: corolla small, white, a little longer than the 5-parted calyx: berries green, as large
as a small cherry. — Gen. i. 128.— Plains from Saskatchewan to New Mexico, chiefly as a
weed near habitations and in cultivated ground.

+ + Leaves varying from coarsely toothed to entire: flowers in small pedunculate umbel-like
lateral cymes: corolla white and sometimes bluish: berries usually black when ripe, rarely red or
yellowish, only as large as peas. (Section Morella, Dunal.)

S. nigrum, L. Low, green and almost glabrous, or the younger parts pubescent:
leaves mostly ovate with a cuneate base, irregularly sinuate-toothed, repand, or some-
times entire, acute or acuminate: calyx much shorter than the corolla.— Includes many
and perhaps most of the 50 and more species of Dunal in the Prodromus, weeds or weedy
plants, widely diffused over the world, especially the warmer portions. A. Braun’s charac-
ters for geveral species, founded on the hairiness or smoothness of the filaments, length
of the anthers and of the style, and whether the calyx is loosely appressed to the ripe
berry or reflexed, do not hold out. Our common form, the true S. nigrum, has corolla only

3 or 4 lines in diameter, filaments more or less hairy inside, style little if at all projecting,
and fruiting calyx merely spreading. To this belongs mainly the following, referred to N.
America by Dunal : viz. S. pterocaulon, Dunal. (Dill. Elth. t. 275, fig. 356), S. crenato-dentatum,

Var. Dillénii. Taller and leaves mostly entire or merely repand: filaments more or
less bearded, at least at the base: style exserted or sometimes not exceeding the stamens.
— Dill. lc. fig. 355. 4S. Dilleni’, Schult., Dunal, 1. c.; A. Braun, Ind. Sem. Hort. Berol.
1853. — Florida to 8. America. Entire-leaved forms differ from the next only in the hairy
filaments. S. Americanum, Mill. Dict., with glabrous leaves, should be the same, but S.
Besseri, Weinm., to which Dunal refers it, is a canescently-puberulent variety, with rather
large and entire leaves. (S. American.)

Var. nodiflorum., Slender, often tall: leaves entire, rarely few-toothed, acuminate :
filaments glabrous: style generally exserted : calyx in fruit reflexed. — S. nodiflorum, Jacq.

berry large, scarlet.

S. Pseupo-CArsicum, L. (JerusateM Cuerry.) Low erect shrub, with spreading
branches, very leafy, glabrous: leaves oblanceolate or oblong, often repand, bright green

Lond. ii. t. 5; Bigel. Med. t. 18. —Near dwellings and in low grounds, Northern Atlantic
States. (Nat. from Eu.)

S. triquétrum, Cav. Nearly glabrous: stems suffruticose, flexuous or sarmentose,
hardly at all climbing, a foot to a yard high: branches angled but hardly triquetrous :
leaves deltoid-cordate (and the larger 2 inches long), varying to hastate, and,in smaller
forms to hastate-3-lobed or even 5-lobed, with the middle lobe lanceolate or linear
and prolonged (an inch or only half an inch long): cymes commonly umbellately few-

4 inches long, and the violet corolla fully an inch and a half in diameter: branches and
the forking cyme villous. —Island of Santa Catalina off San Pedro, California, Wallace.
(Coulter’s no. 586, without flowers, may be a glabrous form of this.)

S. umbelliferum, Esch. Woody below, tomentose-pubescent and cinereous with short
many-branched hairs, sometimes glabrate: flowering branchlets mostly short and leafy :
leaves rarely ovate and acute, commonly obovate and oblong, obtuse, entire, half inch to

This early name of Miller, taken up for the present species in Proc. Am. Acad. |. ¢., must
from the size of the flower belong to it, or to a broad-leaved and hairy form of P. lanceolata.

latter; but the color as well as size of the corolla and the “ pale yellow ” fruit, also the
diffuse growth, best accord with this common species.

OrpER XCVI. SCROPHULARIACEZ.

Herbs, shrubs, or rarely small trees, with leaves either alternate or opposite
and destitute of stipules, primary inflorescence centripetal and the secondary when
developed centrifugal, perfect flowers with the bilabiately irregular corolla (2)
imbricated and not plicate in the bud, didynamous or diandrous stamens, 2-celled
ovary with axile several-many-ovuled placenta, usually capsular fruit, and ana-
tropous or amphitropous seeds (generally numerous), with a small and straight or
only slightly curved embryo in fleshy albumen, the cotyledons little if at all
broader than the radicle. The calyx and corolla are mostly 5-merous, and the
former persistent ; but sometimes they are 4-merous, at least apparently, and

either with or without all four stamens present ; sometimes the corolla is nearly
or quite regular, and even with all five stamens present and complete (uniformly
so in Verbascum, abnormally in several species of Pentstemon) ; and the ovules
are sometimes few and definite, rarely solitary. The posterior or superior stamen
is the deficient or abortive one. Corolla wanting in one Synthyris. Style one
and undivided: stigma either entire, or 2-lobed, or bilamellar (bilabiate) ; its lobes
and the cells of the ovary anterior and posterior. Seeds comparatively small,
rarely winged. — This large order has its tribes arranged by Bentham and Hooker
(Gen. ii. 915) under three series, hardly to be regarded as suborders, the first of
which closely connects with the preceding order, except as to inflorescence. The
ambiguous Salpiglossidee are referred to that order.

I. (PseuDOSOLANE#.) Leaves all alternate. Inflorescence simply centri-
petal. Corolla hardly if at all bilabiate; the 2 posterior lobes external in the
bud. All five stamens sometimes present and perfect.

Tripe I. LEUCOPHYLLEZ®. Corolla campanulate or short-funnelform; the lobes
plane or merely concave.

1. LEUCOPHYLLUM. Calyx short, 5-parted; the lobes nearly valvate. Corolla with
5 rounded and spreading nearly equal lobes. Stamens 4 and didynamous, or rarely 5 and
the fifth imperfect, included: anthers with cells confluent at the apex, at length divari-
cate. Stigma emarginate or bilamellar. Capsule 2-valved, and the valves at length 2-
cleft. Tomentose shrubs.

Trise I. VERBASCEZ. Corolla rotate, with hardly any tube. Anthers by con-
fluence 1-celled. (None indigenous to America.)
2. VERBASCUM. Stamens 5, all with anthers; all or the three superior filaments

woolly-bearded. Style flattened and dilated at apex. Capsule globular or oblong, septi-
cidally 2-valved; the valves 2-cleft at apex. Seeds very numerous, rugose.

II. (ANTIRRHINIDEHX.) Leaves prevailingly opposite, at least the lower. In-
florescence when simple centripetal, when compound the partial centrifugal ; 2. e.
the peduncle cymosely few-several-flowered. Upper lip or lobes of the corolla
external in the bud, with a few occasional and irregular exceptions. Fertile
stamens very seldom more than four.

Tre IT. ANTIRRHINEZ. Corolla bilabiate and more or less tubular; the base
of the tube gibbous or saccate or spurred on the lower side, and the lower lip often
with an intrusion (palate) at the throat. Capsule opening by irregular perforations
or lacerate chinks, not by normal valves, many-seeded. Inflorescence simple and
racemose, or the flowers solitary and axillary.

* Stamens 4, with more or less 2-celled fertile anthers.

3. LINARIA. Corolla with a spur at base (this rarely abortive) and a prominent palate
nearly closing the throat. In the occasional monstrosity called Peloria, the corolla be-
comes regular by the production of 5 spurs and 5 regular short lobes.

4. ANTIRRHINUM. Corolla merely saccate or gibbous at base, otherwise nearly as
Linaria, or the palate in some species much less prominent. Seeds destitute of any proper
wing.

5. MAURANDIA. Corolla barely gibbous at base, nearly funnelform, ringent, with two
longitudinal and commonly bearded intruded lines or plaits instead of palate. Capsule
equal or hardly oblique. Seeds winged or wingless.

2-lobed, the lower 3-lobed and bearing a prominent but comparatively small palate, bearded
down its middle; lobes all broad, erose-denticulate, and abruptly short-acuminate. An-

confluent. Sterile filament small and short, or even minute, naked. Style filiform: stig-
ma minute, entire. Capsule oblong, enclosed in the marcescent calyx and corolla, loculi-
cidally 2-valved, and the valves soon septifragal and 2-parted; placental dissepiment

stigmas which therefore are superposed to (instead of alternate with) the parietal
placente. When the latter are four, it is because the half-placente are borne

OrpDER XCVIII. LENTIBULARIACE.

Herbs, growing in water or wet soil, when terrestrial acaulescent, with scapes
or scapiform peduncles simple and one-few-flowered, calcarate corolla always
and calyx usually bilabiate, a single (anterior) pair of stamens, confluently one-
celled anthers contiguous under the broad stigma, no hypogynous disk, and a free
one-celled ovary with free central multiovulate placenta (either sessile or stipi-
tate) which becomes a globular many-seeded capsule ; the anatropous seeds with
a close coat, no albumen, and filled by the apparently solid ellipsoidal or oblong
embryo. Style short or none: stigma bilamellar, or the smaller anterior lip
sometimes obsolete. Upper lip of the corolla commonly erect or concave, or the
sides replicate, from entire to 2-lobed, interior in the bud ; lower larger, spreading
or reflexed, 3-lobed, with a palate projecting into the throat and a nectariferous
spur beneath. Flowers always perfect. Capsule commonly bursting irregularly.
— The following are the two principal genera. (For action of bladders of Utri-
cularia and leaves of Pinguicula, see Darwin, Insectivorous Plants, p. 868-453.)
1. UTRICULARIA. Calyx 2-parted or deeply 2-lobed; lobes mostly entire, nearly equal.

Upper lip of strongly bilabiate and more or less personate corolla erect. Filaments thick,

strongly arcuate-incurved, the base and apex contiguous. Dissected foliage or stems of

aquatic species bladder-bearing.

2. PINGUICULA. Calyx with upper lip deeply 3- and lower 2-cleft or parted. Corolla
ringent or less personate, and the lobes all spreading. Filaments straighter: anthers nearly
transverse. Terrestrial, with entire rosulate leaves next the ground.

1. UTRICULARIA, L. Brapperworr. (Utriculus, a little bladder.)
— Cosmopolitan small herbs: terrestrial species with inconspicuous or fugacious
radical leaves ; aquatic with the dissected leaves, branches, and even roots, bearing
little bladders, which are furnished with a valvular lid, and commonly tipped with
a few bristles at orifice. Scapes one-flowered or racemosely several-flowered, in
summer. — Lentibularia, Vaill.

§ 1. Scape bearing an involucriform whorl of dissected leaves, which are buoyant
by ample inflated-bladdery petioles filled with air: cauline leaves of the immersed
branching stems capillary-dissected and bladder-bearing, in the manner of the fol-
lowing section: roots few or none.

OrpEeR XCIX. BIGNONIACE.

Trees or shrubs, either erect or scandent (very rarely herbs), with mostly oppo-
site leaves, and large and showy flowers, with more or less bilabiate corolla, tetra-
dynamous or diandrous stamens, single style and bilabiate stigma, and numerous
anatropous ovules of the preceding orders ; distinguished from them by the large
and flat usually winged and transverse exalbuminous seeds, indefinitely numerous,
on parietal placenta, or usually on a partition which separates from the two valves
of the capsule in dehiscence, although in the ovary and when the ovules are in
many rows the placentation often appears to be central; the cotyledons broad
and thin, plane, commonly emarginate or 2-lobed, and the short straight radicle
included in the basal notch. Capsule either loculicidal or septicidal, often silique-
like. Anthers 2-celled: suppressed stamens commonly represented by rudimen-
tary filaments. Corolla bilabiately imbricated in the bud (in our genera, in a few
others valvate). Calyx gamosepalous. Leaves compound, or in two of our genera
simple ; sometimes a pair of basal leaflets and sometimes an axillary pair of leaves
imitate stipules. Chiefly a tropical and rather large order; but few North
American.

late or cylindraceous-ampliate above the narrow and short proper tube, somewhat equally
bilabiate—5-lobed. Anther-cells divergent, glabrous. Capsule linear, compressed parallel
with the flat valves and partition, marginicidal and septifragal, a filiform margin usually
separating all round both from the edges of the valves and the partition. Seeds attached
in a single series on each side of both margins of the partition; the thin wing entire. Ten-
dril-climbers.

2. TECOMA. Calyx distinctly 5-toothed. Corolla funnelform or somewhat campanulate
above the short proper tube, somewhat bilabiately 5-lobed. Anther-cells divergent,
glabrous or sparsely pilose. Capsule narrow, somewhat terete or turgid, loculicidal and
septifragal; the valves contrary to the partition. Seeds imbricated in one or two or more
series on each side of the margins of the partition; the wing hyaline. Rootlet-climbing or
erect shrubs; flowers in terminal panicles or corymbs.

ORDER C. PEDALIACE.

Herbs, with mucilaginous or watery juice, chiefly opposite simple leaves, and
flowers as of the preceding order (to which it has more usually been annexed),
except in the structure of the ovary and fruit. Ovary either one-celled with two
parietal intruded placentae expanded into two broad lamellae or united into a
central columella, or variously 2—4-celled by the extension of the placente and by
spurious partitions from the wall. Fruit capsular, drupaceous, or nucumentaceous,
few—many-seeded. Seeds wingless, mostly with a thick and close coat, filled by
the large embryo; the cotyledons thickish. — A small extra-European and mainly
African order, or suborder, of warm climates, represented in the United States by
one sparingly naturalized, and one or two probably indigenous species.

1. SESAMUM. Calyx herbaceous, 5-parted, persistent. Corolla ventricose-campanulate
or funnelform ; limb bilabiately 5-parted, spreading; upper lobes smaller. Stamens didy-
namous: anther-cells parallel. Stigmas linear. Fruit an oblong quadrangular and 4-sul-
cate capsule, septicidal at summit, spuriously 4-celled, a false partition from the dorsal
suture of each of the two carpels reaching the columnar placenta at the centre. Seeds
numerous in a single series in each half-cell.

2. MARTYNIA. Calyx 1-2-bracteolate, membranaceous, somewhat bladdery-campanu-
late, 5-cleft, sometimes splitting anteriorly to base, deciduous. Corolla ventricose-funnel-
form or campanulate, somewhat oblique or decurved; the lobes of the bilabiately 5-
parted limb broad, somewhat undulate, slightly unequal. Stamens 4, strongly didynamous,
or sometimes only the anterior pair antheriferous: anthers tipped by a gland; the cells
divaricate. Stigma bilamellar. Ovary one-celled, with two parietal placentae which
meet in the axis and there diverge in broad lamelle, bearing single or double rows of
ovules. Fruit fleshy-drupaceous, tapering into an incurved beak: fleshy exocarp at
maturity 2-valved and deciduous: endocarp fibrous-woody, scrobiculate, cristate at the
sutures, 2-valved through the slender beak to the summit of the cells, indehiscent below ;
the cavity by the extension of the placente to the walls 4-locellate, and with a small
empty central cavity. Seeds rather numerous, oblong, large, with a thick and somewhat
spongy tuberculate-rugose coat. Cotyledons obovate, fleshy: radicle very short.

odor; with ample rounded and subcordate petioled leaves, the lower usually oppo-
site and upper alternate, and large flowers in short and loose terminal racemes :
pedicels subtended by small bracts or none. Fl. summer.— Our species belong
to § PrososcrpEA, having 4 perfect stamens and beak longer than the body of
the fruit, and the calyx is more cleft anteriorly.

M. proboscidea, Glox. Coarse and heavy-seented annual: leaves cordate, roundish,
often oblique, entire or obscurely undulate-lobed (4 to 12 inches in diameter): bractlets
oblong-linear: corolla 14 or 2 inches long, dull white, spotted within with some yellowish

OrDER CI. ACANTHACEA.

Chiefly herbs, with opposite simple leaves, no stipules, and didynamous or dian-
drous more or less bilabiate or irregular flowers with the general characters of
Scrophulariacee, &c.; but corolla not rarely convolute in the bud; the anatropous
ovules few and definite (from 2 to 8 or 10 in each of the two cells); fruit always
capsular, 2-celled, elastically loculicidal scattering the seeds; seeds without
albumen (except sparingly in the first tribe), either globose, or orbicular and com-
pressed and the hilum marginal, wingless, in most supported on the upper face
of curved processes from the placenta (indurated and persistent funiculi ?) called
retinacula, the close coat not rarely developing mucilage and spiricles when
wetted, in the manner of Polemoniacee@. Cotyledons plane, orbicular with cordate
base: radicle straight or accumbently incurved. Hypogynous disk conspicuous.
Style filiform, undivided, with one or two small stigmas. Corolla from almost
regular and 5-lobed (and then conyolute in the bud) to deeply bilabiate (or in
Acanthus with only a lower lip). Calyx persistent, of 5 or sometimes 4 sepals,
commonly unequal and more or less imbricated, sometimes united. Inflores-
cence various: flowers usually conspicuously bracteate and often 2-bracteolate.

Stems commonly quadrangular. Cystoliths abound in the foliage. — A large

OrDER CIV. LABIAT 4.

Herbs or low shrubs, with aromatic herbage (usually dotted with small im-
mersed glands replete with volatile oil), with square stems, opposite simple leaves
and no stipules; the perfect flowers with irregular more or less bilabiate corolla,
didynamous or diandrous ; filiform style mostly 2-cleft and 2-stigmatose at apex,
and around its base the divisions of a 4-parted (sometimes only 4-lobed) ovary,
which are uniovulate and ripen into akene-like nutlets, in the bottom of a gamo-
sepalous calyx. Ovule and seed mostly amphitropous or anatropous, and erect.
Embryo straight except in the Sceutellarinee, with plane or plano-convex coty-
ledons and inferior radicle: albumen usually none or hardly any. Lobes of the
corolla imbricated in the bud, the posterior or the upper lip exterior and the
middle lobe of the lower lip innermost. Stamens borne on the tube of the corolla.
distinct or rarely monadelphous ; the fifth (posterior) stamen, and in diandrous
flowers the adjacent pair also, not rarely represented by sterile filaments or rudi-
ments: rarely the 4 fertile stamens equal. Hypogynous disk generally present,
sometimes as (one to four) gland-like lobes. Pistil as in all the related orders
dimerous, each carpel deeply 2-parted or 2-lobed. Inflorescence thyrsoidal ; the
general evolution of the clusters in the axils of leaves or primary bracts (these
occasionally reduced to single flowers) centripetal; that of the clusters (cymes or
glomerules) centrifugal. The pair of sessile clusters, one to each axil, having
the appearance of a whorl (verticil) form what has been termed a verticillaster.
Bracts or bractlets various. Leaves occasionally verticillate. Seed transverse
and the radicle incurved in Scutellarinee. (The Ajugoidee connect with the
tribe Viticee of the preceding order, and therefore are placed foremost. A
larger proportion of our Labiate are Old World naturalized plants than of
any other order.) — Benth. Lab. & in DC. Prodr. xii. 26; Benth. & Hook. Gen.
ii. 1160.

ORDER CV. PLANTAGINACEA.

An anomalous order of Gamopetala, chiefly acaulescent herbs with one—several-
ribbed or nerved radical leaves, simply spicate inflorescence, and regular 4-merous
flowers having a free ovary, a filiform and entire long-stigmatose style, amphi-
tropous and peltate ovules and seeds, a mostly straight embryo in firm-fleshy
albumen, the cotyledons little broader than the radicle, and the corolla searious

,

and veinless, mostly marcescent-persistent. Consists chiefly of the two following
genera; the principal genus of many species and widely dispersed over the
world, but most largely European and Asiatic; the other of a single species
widely dissevered in habitation.

1. PLANTAGO, Tourn. Pranrary, Ripworr. (The Latin name.) —
Flowers perfect or polygamo-dicecious, each subtended by a bract. Calyx of
4 imbricated sepals, persistent. Corolla salverform with a short tube, or nearly
rotate ; limb 4-parted; lobes imbricated in the bud, two lateral exterior. Stamens
4, or sometimes 2, on the tube of the corolla: filaments commonly capillary :
anthers 2-celled, versatile. Ovary 2-celled (or rarely falsely 3—4-celled), with one

‘

or more ovules in each cell. Style or stigma mostly hairy. Capsule (pyxidium)
circumscissile toward the base, and with a loose partition falling away with the
lid; the seeds attached to its face. Seed-coat developing copious mucilage
when wetted. Scape from the axils of the radical or subradical leaves, mostly
bearing a single simple spike or head of greenish or whitish small flowers, in
summer.

§ 1. Stamens 4: flowers all perfect: corolla not closed over the fruit.

* Flowers dichogamous, proterogynous; the style projecting from the apex of the unopened
corolla; the anthers long-exserted on capillary filaments after the corolla has expanded.

+— Corolla glabrous (as also the whole inflorescence, except in P. macrocarpa): seeds not hollowed
(or barely concave) on the inner face: leaves 3-8-nerved or ribbed, plane: root perennial.

++ Ribs or nerves of the broad leaves mainly confluent with the thick and dilated lower portion of
the midrib: ovules only 2 in each cell: seeds by abortion sometimes solitary.

P. cordata, Lam. Very smooth: leaves cordate or ovate (3 to 8 inches long), sometimes
repand-dentate, long-petioled, 7-9-ribbed: scape fistulous, stout, a foot or two high, includ-
ing the narrow spike: bracts rotund-ovate, very obtuse, as are the ovate and obovate sepals
and the corolla-lobes: capsules broadly ovoid, twice the length of the calyx: seeds 4 to 2,
large, oblong. — Ill. i. 338; Jacq. Eclog. t. 72. P. Kentuckensis, Michx. FI. i. 94. — Along
streams (Canada? Pursh), New York to Wisconsin and Louisiana, common only westward.

++ ++ hibs or nerves of the leaf free quite to the contracted base.

== Leaves ovate or oval, or in small forms oblong, rarely subcordate, several-ribbed, base abruptly
contracted into a distinct petiole, not fleshy, glabrous or pubescent, from entire to sparingly re-
pand-dentate: ovules and seeds at least 2 in each cell: scapes with the spike a span to 2 feet high.
P. major, L. (Common Piantain.) Spike commonly dense. obtuse at apex: sepals
rotund-ovate or obovate, scarious-margined ; the exterior and the bract more or less cari-
nate: ovules 8 to 18: seeds as many or by abortion fewer, small, angled by mutual press-
ure, usually light brown, minutely reticulated: capsule ovoid, very obtuse, circumscissile
near the middle and near the level of the summit of the sepals. — Waysides and near
dwellings throughout the country, doubtless introduced from Europe, but also native from
Lake Superior far northward. Runs into some monstrosities and several varieties, an
extreme in saline soil being var. minima, Decaisne in DC. Prodr. xiii. 695 (P. minima, DC.),
with scapes 2 to 5 inches high, and leaves proportionally small. (Cosmop.)

Var. Asidtica, Decaisne. Capsule usually more broadly ovoid, circumscissile
near the base and much within the calyx. — P. Asiatica, L. Spec. i. 113; Franchet &
Savatier, Enum. Pl. Jap. 384. (Includes perhaps P. Kamtschatica, Cham. and Link, or
plants cultivated as such, with 4, 5, or 6 seeds.) — A very large indigenous form, coast of
California near San Francisco (capsule globose-ovoid) to the borders of British Columbia;
Saskatchewan to the Arctic Sea. Perhaps a distinct species. (N. Asia, Himalaya.)

P. Rugélii, Decaisne. Leaves paler, commonly thinner: spikes long and thin, atten-
uate at the apex: sepals oblong, all as well as the similar bract acutely carinate: cap-
sules erect in the spike, cylindraceous-oblong (somewhat over 2 lines long, one-sixteenth

inch in diameter), about twice the length of the calyx, circumscissile much below the
middle: ovules 6 to 10: seeds 4 to 9, oval-oblong (about a line long), opaque and dull
brown, not reticulated. — Prodr. ]. ¢. 700, founded on a small and slender 4-seeded form.

crown: leaves membranaceous, lanceolate-spatulate, entire or obsoletely denticulate, ob-
scurely 3-5-nerved, 1 to 3 inches long, attenuate into a shorter margined petiole: spike
slender but densely flowered, an inch or more long: bracts and sepals short (only a line
long), pale with greenish midrib, little over half the length of the oblong capsule. —N. W.
Wyoming, on grassy slopes of the East Fork of the Yellowstone River, Frank Tweedy, Aug.,
1885, in fruit.

c. Maritime or in saline soil: leaves thickish and somewhat fleshy: ovules a pair in each cell.

ADDITIONS AND CORRECTIONS.

LOBELIACE.

The following are additions and corrections to the generic characters of this
order, on p. 2: —

1. NEMACLADUS. Filaments either partly or almost wholly monadelphous. Seeds oval
or globular, obscurely costate or striate longitudinally and somewhat favose or transversely
reticulate between the ribs.

11, PARISHELLA. Calyx 5-cleft, with campanulate tube wholly adnate to the ovary and
shorter than the spatulate foliaceous lobes. Corolla almost rotate, shorter than the calyx,
deeply and nearly equally 5-cleft. Stamens free from the corolla: filaments distinct at base
only, above connate into a slender tube with inflexed summit. Style filiform: stigma de-
pressed-capitate, 2-lobed, not annulate. Capsule turbinate, inferior, except the low-conical
apex, which is circumscissile close to the base of the calyx-lobes and falls off as a lid. Seeds
globose, smooth and nearly even. Otherwise nearly as Nemacladus.

1°, HOWELLIA. (Under tribe Lobelice.) Flowers of two forms; the emersed corolliferous,
submersed with undeveloped corolla. Calyx with linear-clavate tube adnate for its whole
length to the ovary, and alimb of five nearly equal slender-subulate or filiform segments.
Corolla even in emersed flowers not surpassing the calyx ; its very short tube divided nearly
to base on the (apparently) upper side; lobes oblong, almost equal, three united higher.
Stamen-tube nearly free, and with the included style slightly incurved: anthers oval; two
smaller trisetulose, three larger naked. Ovary strictly one-celled, with two filiform parietal
placent, each 3-5-ovulate. Upper ovules ascending; lower pendulous. Capsule clavate-
oblong or fusiform, with contracted apex, membranaceous at maturity and bursting irregu-
larly on one side. Seeds few and large, linear-oblong, smooth, callous-apiculate at the
chalaza. Aquatic herb.

1. NEMACLADUS, Nutt. Genus now increased in number of species

and forms.

N. ramosissimus, Norr., p. 3. Rarely a little puberulent: filaments usually monadel-
phous for most of their length, sometimes separating below in age. Nuttall’s original is
the more slender and very diffuse form, most abundant in Lower California, W. Arizona,
and S. W. Utah, with very small white corolla little surpassing the calyx, and roundish seeds.
— N. tenuissimus and N. capillaris, Greene, Bull. Calif. Acad. i. 198, 196.

Var. pinnatifidus (V. pinnatifidus, Greene, 1. c.) is less diffuse and has the (glabrous)
radical leaves irregularly pinnatifid, and their small lobes commonly 1-2-toothed. —
Sierra Madre Mountains, Los Angeles Co., O. D, Allen. (AIl Saints’ Bay, Lower Cali-
fornia, Greene.)

Var. montanus (JN. montanus and N. rubescens, Greene, |. c.). More erect, a span or
two high, with larger flowers and fruit, on less divaricate or ascending pedicels : column more

to oblong-oval. — N. ramosissimus, Torr. Bot. Mex. Bound. t. 35, is one of the forms of this.
— From Middle and through 8. E. California to the 8. W. border of Texas.

N. longiflorus, Gray, p. 3. Habit of the last preceding form, well marked by its longer
corolla and elongated free capsule.

N. rigidus, Curran. Stout and coarse for the genus, rather fleshy and thickish-leaved,
purplish : calyx with triangular-subulate lobes somewhat surpassing the short corolla, and
tube adnate quite to the middle of the remarkably large (2 lines wide) globular capsule :
seeds (nearly half-line long) oval, under a good lens broadly costate and the ribs cross-barred
as in N. ramosissimus, var. montanus. — Bull. Calif. Acad. 1. 154. — Nevada, on Geiger’s Grade,
near Virginia City, Mrs. Layne-Curran. This might throw some doubt on the following
genus; but it has the bivalvular dehiscence of Nemacladus.

leaves linear-setaceous and elongated, mostly alternate, entire; emersed ones shorter and
broader, sometimes 1-2-toothed: flowers axillary, short-peduncled: only submersed capsules
known, these half-inch long. — In stagnant ponds on Sauvies Island, Columbia River, at the

3. PALMERELLA, Gray.

P. débilis, Gray, p. 8. Not rare from mountains near Santa Barbara (Mrs. Cooper, 1878)
and San Bernardino Co. to Lower California. An interesting addition to the generic char-
acter, detected by Mr. Nevin, is that the throat of the corolla on the (apparently) upper side
bears a nectary, as if an adnate spur, forming a narrow imperfectly tubular cavity, reaching
down to the insertion of the filament-tube on that side.

5. DOWNINGIA, Torr. P. 9, add: —

D. bicorntta. Most like D. pulchella, more ascending or erect, short-leaved: corolla
intensely blue with white centre; lip with short lobes, and a strong constriction above the
auriculate base, the face of which bears a pair of conspicuous conical hollow appendages. —

G. diffisa, Gray. Slender and diffusely much branched, small-leaved, glabrous and
smooth: calyx-lobes subulate-lanceolate from a broad base, about equalling the small corolla
and half the length of the linear closely sessile capsule: seeds short-oblong. — Proc. Am.

C. scabrélla, Encerm. Cinereous-puberulent or minutely scabrous to nearly or quite gla-
brous: numerous stems from the multicipital caudex 2 to 5 inches high; larger ones
2-4-flowered: leaves thickish; radical spatulate, upper cauline linear: flowers more erect
and rather larger than in C. uniflora: lobes of corolla ovate-lanceolate, as long as its cam-
panulate tube: capsule oblong-turbinate, not narrowed at summit. — Bot. Gazette, vi. 237.—
Higher mountains of N. California and Washington Terr., Engelmann (1880), Pringle, Suks-
dorf, Howell, Brandegee.

C. Parryi. A span to a foot high from elongated and creeping filiform rootstocks, mainly
smooth and glabrous: stem slender, erect, simple and with slender-peduncled flower, or with
some lateral leafy branches: leaves thinnish, entire or sparingly callous-denticulate, some-
what veiny; radical and lower spatulate or lanceolate with tapering base hirsute-ciliate ;
upper linear-lanceolate from a sessile base, attenuate-acute: flower erect in anthesis : corolla
almost crateriform, 5-lobed to middle, spreading to a full inch in diameter, violet-blue or even
purplish, little surpassing the linear-subulate often callous-denticulate calyx-lobes: ovary
turbinate: capsule nearly obovate, opening close under the base of the erect calyx-lobes. —

C. pLAnirLOra, Lam., on p. 14, a species long ago in cultivation, was wrongly guessed to be

American. It is very near C. pyramidalis, L., of S. E. Europe, perhaps a variety of it.

C. rotundifolia, L. To this polymorphous species refer all the forms assembled under
“C. Scheuchzeri” (not Vill.), excepting what belongs to C. Parryi, and (to avoid the ques-
tion as to what is truly C. linifolia, Lam., and C. Scheuchzeri, Vill.) adopt the nomenclature
of Lange, viz. : —

Var. arctica, Lange, FI. Dan. xvi. 8, t. 7211 (C. linifolia, var. Langsdorffiana, A. DC.,
and probably his C. dubia and C. pratensis, also C. rotundifolia, var. linifolia, Gray, Man. ed. 2,
244, not Wahl. Fl. Lapp.), for the more rigid and one-few-flowered form, with corolla
usually inch long, and very slender calyx-lobes soon spreading or deflexed. — Common from
Canada and Labrador to the arctic regions.

Var. Alaskana. Leafy to the top: radical leaves cordate; lowest cauline ovate, the
succeeding ovate-lanceolate to lanceolate, nearly all petiolate: calyx-lobes attenuate, soon
deflexed : corolla an inch to nearly an inch and a half long. — C. heterodoxa, Bong. Veg. Sitk.

branched : leaves sparingly dentate, half-inch long; radical spatulate, lower cauline lanceo-
late, those of the upper branches almost filiform and entire: flower and fruit erect on almost
capillary peduncles: corolla blue, oblong-campanulate, with ovate-lanceolate lobes rather
shorter than the tube: capsule obovate, crowned with the somewhat shorter narrowly linear-
lanceolate erect calyx-lobes, opening near the base ?—On granite rocks, House Mountain,

H. mfyimum, Kellogg, Proc. Calif. Acad. vii. 111, by the character is clearly Alchemilla
arvensis.

ERICACEA.

1, GAYLUSSACIA, HBK.

G. frondésa, Torr. & Gray, p.19. To this is to be added : —

Var. nana. Stems lower and strict, only a foot or so high: leaves more reticulated in
age and smaller than in the ordinary plant: racemes and their pedicels shorter. — Pine bar-
rens of Florida, &c. Apparently there the commoner form, of which the var. tomentosa
is a downy-leaved state.

2. (VACCINIUM, L:

V. Oxycoéccus, L., p. 25. To the slender and chiefly high-northern form of this belongs
Oxycoccos microcarpa, Turez. Fl. Baic.-Dahur. ii. 195. To this (as being the original
species), rather than to V. macrocarpon, is referred the connecting form of the Pacific
coasts, viz. : —

Var. intermédium. Leaves from ovate to oblong, mostly obtuse, a third to half
inch long: flowers strictly umbellate from the scaly bud, but this not rarely proliferous into
a leafy shoot (in the original of the species very rarely so): berry 4 or 5 lines in diameter. —
Washington Territory and N. Oregon, Suksdorf, Henderson. Also, doubtless, Douglas, in
Hook. FI. ii. 35, referred to V. macrocarpon, very naturally, as leaves of the specimen are
elliptical, oblong, very obtuse, even more so at apex than base, obviously veiny beneath, and
margins hardly at all revolute. (N. E. Asia, Sachalin, Japan, &c.)

V. macrocarpon, Ait., p. 26. Pedicels becoming scattered along the base of a leafy shoot
proliferous from the scaly bud, either squamaceous- or leafy-bracted.

4. ARBUTUS, Tourn. P. 27, add: —

A. Lavuriroiia L. f. The original of this is probably a specimen of A. Unedo (doubtless
of the Old World), in the herbarium of Linnzus, on which Smith has written this name.
The A. laurifolia, Lindl. Bot. Reg. xxv. t. 67, is surely A. Xalapensis, HBK., a variable Mexican
species. The North American forms, other than the A. Menziesii of the Pacific coast, are very
difficult, but seem to be best disposed as follows : —

A. Xalapénsis, HBK., var. Arizonica. Tree 20 to 40 feet high, with a whitish and
thickish scaly bark on the main trunk, but with the reddish close and thin bark of A. Men-

Var. Texana. Low tree, with older bark mostly deciduous in the manner of A. Men-
ziesii: leaves from lanceolate-oblong to oval or ovate, more coriaceous, 2 or 3 inches
long: ovary pubescent. — A. Texana, Buckley, Proc. Acad. Philad. 1861, 460; Sargent, 1. c.
A. Menziesii, Torr. Bot. Mex. Bound. 108. A. Xalapensis in part, Watson, Proc. Am.
Acad. xviii. 111. — Limestone hills of W. Texas, first coll. by Wright. Passes into similar
Mexican forms on one hand, and is too like A. Menziesii on the other.

5. ARCTOSTAPHYLOS, Adans.

A. nummularia, Gray, p. 28. This grows 2 to 6 feet high, has been collected on the
Mendocino plains by Pringle, and near Santa Cruz by Anderson, by the latter with fruit ; an
oblong drupe, only 2 lines long, the thin pulp dry at maturity, and the whole splitting
up into the (mostly 4) thin-shelled nutlets. On this account, Parry, in monograph of
Arctostaphylos, in Proc. Davenport Acad. Nat. Sci. iv. 30, makes this the type of a new
section, Micrococcus.

A. bicolor, Gray, p. 29. Add syn.: A. Veatchii, Kellogg, Proc. Calif. Acad. ii. 19. Also
A. Clevelandi, p. 29, & Proc. Am. Acad. xii. 61, appears to be an abnormal and autumn-
flowering state of this species.

A. POoLIFOLtA, in § 4. Comaristaphylis, to be replaced by

A. diversifolia, Parry, in herb. Shrub 6 to 15 feet high: herbage minutely canescent-
tomentose when young, the inflorescence sometimes hirsute-pubescent and with some small
glandular bristles: leaves glabrate, firm-coriaceous, short-petioled ; those of flowering
branches mostly spatulate-lanceolate, entire or spinulose-serrulate ; of sterile shoots oblong or
oval, either finely or coarsely spinulose-dentate : racemes solitary or clustered, loose: bracts
lanceolate-subulate : calyx 5-parted into subulate divisions: corolla ovate: filaments long-
bearded at base: drupe only 2 lines in diameter and with solid 5-celled putamen. — A. arguta,
var. diversifolia, Parry in Proc. Davenport Acad. Nat. Sci. iv. 35, not A. arguta, Zucc., which
has a different calyx.— Southern borders of California, below San Diego and adjacent
Lower California, O. VN. Sanford, Parry, Orcutt.

A. oppositifolia, Parry. An anomalous species: leaves opposite or in threes, linear,
entire, with revolute margins, much resembling those of Andromeda polifolia: flowers pa-
niculate: corolla globular, a line or two long: ovary canescent: drupe smooth, depressed-
globose ; the putamen separable at maturity into five perfectly or incompletely 2-celled nutlets.

G. Myrsinites, Hoox., p. 30. Strike out the last sentence, and add: Glabrous: leaves
oval or rounded, not ovate, mostly only half-inch long: corolla depressed-campanulate, little
surpassing the calyx. — Gray, Proc. Am. Acad. xix. 84.

G. ovatifolia, Gray, l.c. Larger, with ascending branches; and with some at length
rusty-colored hairs, at least on the calyx: leaves broadly ovate or even subcordate, the lar-
gest an inch and a half long, more serrulate: corolla campanulate, double the length of the
calyx-lobes. — Cascade Mountains, British Columbia to Oregon, Lyall, E. Hall, S. Watson,
Suksdorf, the last of whom indicated the characters.

L. Catesb#i, Gray, p. 34. The words “(4 to 7 inches long)” in line 3, are misplaced :
they relate to the Jeaves. To this, and not to LZ. acuminata, belongs Andromeda acuminata,
Smith, Exot. Bot. t. 89.

398 SUPPLEMENT.

17. RHODODENDRON, L. P. 41, after R. Rhodora, add: —

R. Vaséyi, Gray. Shrub 5 to 15 feet high, nearly glabrous: branchlets wholly destitute of
strigose bristles: flowers rather preceding the leaves, from few-scaled buds: leaves oblong,
acute or acuminate at both ends, sparsely hirsute, at least the midrib and margins when
young, when adult 3 to 5 inches long and 1 or 2 wide: corolia pale rose-color, rotate-
campanulate, but irregular, somewhat unequally 5-parted ; upper lobes shorter and overlap-
ping, somewhat spotted, three lower diverging and widely spreading, all broadly obovate :
stamens 5 to 7, commonly 7: capsule minutely glandular, oblong, acutish.— Proc. Am.
Acad. xv. 48. — Mountains of Jackson Co., N. Carolina, “seven miles southwest of Webster,”
George R. Vasey, and Chimneytop Gap, Donnell Smith, flowering in May. Nearest R. Al-
brechtii of Japan. Requires some extension of the Ahodora subsection.

R. Califérnicum, Hoox., p. 41. Extends north to Brit. Columbia; and the syn. R.
mazimum, Hook. F1., as to the Pacific coast plant, belongs in part, if not wholly, here.

R. macrophyllum, Dov, p.42. This is not yet well made out; but it was originally
described (from the collection of Menzies) as having corolla smaller than of R. maximum,
and white, and leaves large. It should therefore be to R. Californicum what R. maximum is
to R. Catawbiense. But it is doubtful if there are two true species on the Pacific coast.

31. SCHWEINITZIA, Ell. Two species, characterized thus : —

S. odorata, Exx., p. 49. Scales of the stem broadly ovate, imbricating : flowers in a short
spike, hardly nodding: sepals oblong, about equalling the flesh-colored corolla.— Gray,
Proc. Am. Acad. xx. 301.

S. Reynoldsiz, Gray, l.c. More slender, with smaller and remoter scales : flowers more
numerous and smaller, slightly fragrant, soon nodding and mostly secund in the narrow
spike: sepals ovate or lanceolate, half the length of the white corolla.— EK. Florida
near the coast, on Indian River, &c, first found by Miss Mary C. Reynolds, flowering in
winter.

33. PLEURICOSPORA, Gray. P. 50 and 18, add: No hypogynous
disk-glands. Placentz apparently double the petals in number, commonly 8.
Seed-coat close and alveolate.

P. fimbrioldta, Gray. Extends to Oregon: coll. at Waldo by Howell, and on the Colum-
bia at Hood River by Mrs. Barrett.

34. NEWBERRYA, Torr. P. 50 and 18, add: Bract-like sepals 2 or 4,
linear. Disk of short and deflexed glands alternating with the stamens. Now
two species:

N. congésta, Torr., p. 50. Flowers densely crowded in a corymbiform glomerule : lobes of
the corolla ovate, one third the length of the cylindraceous or slightly urceolate tube: fila-
ments equalling the slender style: anthers narrowly oblong, the line of dehiscence close to
the connective: cauline scales ovate, obtuse, only slightly erose. — Gray, Proc. Am. Acad.
xv. 44. Besides Dr. Newberry’s original specimens in the Cascade Mountains of Oregon,
now found in coniferous forests of Mad River, N. W. California, Rattan.

N. spicata, Gray, 1.c. Flowers spicately crowded: corolla more campanulate, with oblong
lobes half the length of the tube: filaments not equalling the short style: anthers short-
oblong, the line of dehiscence somewhat remote from the connective: cauline scales narrowly
oblong, acutish, fimbriate-erose.— Woods, in the mountains of Humboldt Co., California,
Rattan.

D. montana, Gray, p. 60. Leaves wholly destitute of forked hairs, glabrous or nearly so,
but margins ciliolate with short simple bristles, linear or lanceolate, small (1 to 3 lines long),
very crowded on the crowns of the pulvinate-cespitose branches, or in the larger and looser
plants in successively proliferous tufts: peduncles solitary and simple (or rarely in pairs
from the rosulate tuft), naked and 1-flowered, and the calyx often unibracteolate (in one case
a second flower sessile in the axil of the bract): tube of the corolla barely or hardly equal-

ASCLEPIADACE.

The sy peptic! characters of the genera, on p. 85 and p. 87, to be augmented
as follows :

5. ASCLEPIODORA. To character of hoods, add: At the sinuses between them are
auriculate lobes, alternate with the anthers, simulating an inner corona.

141. ROTHROCKIA. Corolla rotate, deeply 5-cleft ; the lobes oblong, dextrorsely over-
lapping in the bud. Crown simple, inserted at the junction of corolla and stamen- tube,
5-parted ; the lobes opposite the anthers, thick, slightly cuneate, barely concave. Anthers
short : pollinia oval, affixed just below their apex to a short caudicle, pendulous. Stigma
abruptly produced from the top into a column having a 3-crested apex; namely, two divari-
cate and muricate-papillose crests, with a small central emarginate crest interposed.

142. HIMANTOSTEMMA. (In Tribe Gonolobee?) Corolla deeply 5-parted, soon re-
flexed, the broadly lanceolate lobes slightly overlapping dextrorsely, the face (especially
toward the base) conspicuously adorned with spatulate and stipitate corolline processes, dis-
posed without order. Crown stamineal, borne on the summit of the short column, simple,
with membranaceous margin bearing 10 elongated narrowly linear and stipitate liguliform
divisions, which are geminately alternate with the anthers and nearly equal the unex-
panded corolla ; also 5 subulate and short processes, which are opposite the anthers.
Anthers short, inappendiculate in the manner of Gonolobew, applied to the sinuses of the
somewhat dilated and flat-topped stigma: cells opening at summit. Pollinia oval, affixed
by the pellucid apex to a very short caudicle, introrsely somewhat pendulous. Follicles
echinate.

143. LACHNOSTOMA,. Corolla between rotate and salverform, with tube about the
length of the (in bud) dextrorsely convolute lobes, retrorsely villous-barbate in the throat.
Crown belonging to the corolla, adnate to its tube, with free margin 5-10-crenate or
lobed. Otherwise near Gonolobus.

POLEMONIACE A.

The genera are very difficult to define. Even Phlox has a species with prevail-
ingly alternate leaves and four or five ovules in each cell. The character of
unequally inserted stamens, by which to distinguish Collomia, breaks down com-
pletely (Proc. Am. Acad. xvii. 223); the declination of the filaments does not
hold through Polemonium, and they are much more declinate and curved in sev-
eral species of Gilia of different sections. Some, of more than one group, have
an obviously but variably irregular limb to the corolla, quite as much so as in any
species of Leselia. So it has become necessary to incorporate Collomia into
Gilia, along with certain bractless species which had been taken to form an
anomalous section of Leselia. The principal characters now relied upon for the
genera are indicated below.

4. (to be 2.) GLLIA, Ruiz & Pav. — Flowers naked, not involucellate.
Calyx partly herbaceous, scarious below the sinuses; lobes narrow and acute.
Corolla from salverform or funnelform to campanulate or almost rotate. Fila-

G. Wrightii, Gray, and G. Gunnisoni, are between § Hugelia and § Ipomopsis, and
might well be referred to the latter: their filaments are obscurely declined. The following
may be appended to the present section, after G. polycladon.

G. depréssa, M. E. Jones. Small winter annual, divergently branched from the base,
depressed-spreading, minutely hirsute-pubescent, slightly viscid, leafy : leaves oblong-lanceo-
late or narrower (half-inch or more long), entire or with one or two teeth or short lobes,
acute at both ends, nearly sessile, cuspidate-mucronate: flowers solitary in the forks, short-
peduncled or subsessile: calyx comparatively large (2) to 3 lines long) ; its lobes broadly
subulate and attenuate-cuspidate, nearly equalling the small salverform (whitish) corolla:
limb of the latter sometimes deeper cleft at one ne ; 1ts lobes about one third the length
of the tube, equalling the stamens: seeds 4 or 5 in each cell, the coat mucilaginous but not
spirilliferous. — Gray, Proc. Am. Acad. xvi. 106. — Arid districts of S. Utah, Nevada, and
adjacent borders of California, M. £. Jones, Parry, Shockley.

§ 9. Ipomopsis, p. 145. — Char. revised. Flowers thyrsoid-paniculate and
either glomerate or open (rarely diffuse), with narrow if any bracts: these and
the calyx-teeth not pungent-tipped: corolla salverform or by gradual dilatation
of the tube trumpet-shaped, mostly elongated: stamens inserted in or below the
throat, either equally or unequally: laments not rarely declined-incurved :
ovules and seeds few or numerous in the cells. -— Includes Collomia § Phlogan-
thea, and Leselia § Giliopsis, pp. 135, 136, also Gilia § Giliandra, p. 146.

G. coronopifolia, Prrs., p. 145.— Although the thickened cellular seed-coat does “ not
develop mucilage nor spiral threads when wet,” yet there are such threads in the cells,
which can be drawn out.

G. aggregata, SprenG., p. 145. Stamens in some plants equally inserted and of equal
length, in others areneelly inserted, either slightly or excessively. —Collomia aggregata,

G. Thurberi, Gray, Proc. Am. Acad. xvii. 223, & p. 136. Collomia Thurberi, Gray, p
136.— Seemingly a perennial: corolla commonly an inch and a half long: stamens more

serted from the throat, but all shorter than the lobes of the corolla. — Not rare in the moun-
tains of 8. Arizona, coll. Buckminster, Lemmon, Pringle.

G. Macombii, Torr. in herb. Seemingly a suffrutescent-based many-stemmed perennial,

leaves mostly pinnately parted (or even those subtending the flowers 3-parted) into filiform
rigid lobes no broader than the rhachis: flowers scattered, mostly short-peduncled : calyx
hirsute ; its lobes slender-subulate and almost spinulose, nearly twice the length of the cap-
sule: tube of the nearly salverform corolla barely twice the length of the calyx (a quarter-
inch long) and hardly longer than the somewhat irregular or oblique limb ; its lobes oval,
obtuse, mucronulate: filaments equally inserted, as long as the corolla-lobes, conspicuously
declined-incurved: ovules several in each cell. — Leselia Havardi, Gray, Proc. Am. Acad.

the lobes being separated from the others by deeper sinuses; corolla-lobes more or less cuneate
and erose-truncate or 3-denticulate: filaments capillary, incurved-declined toward the apex in

glabrous, leafy, paniculately several-flowered: leaves nearly filiform or acerose, all entire:
corolla violet or purplish and commonly spotted with deep-colored dots; its slender tube

G. débilis, Warson, p. 147. G. Larseni, Gray, of the preceding page, is only a smaller and
more condensed state of this, growing in loose volcanic ashes, there only with long and

G. Nevinii. Next to G. multicaulis, p. 147, much more pubescent with short and above with
viscid hairs: leaves 2-3-pinnately parted into more numerous lobes which are not broader
than the rhachis: flowers several and subsessile in the terminal glomerules: corolla violet,
with narrow tube and little dilated throat together 4 or 5 lines long and double the length
of the calyx, the limb comparatively small: capsule oblong, with 10 or 12 seeds in each cell.

G. latifléora, p. 147. Foliage often lightly tomentulose, when young glabrate: calyx very
scarious below the sinuses to the base, glabrous or minutely glandular. Varies in size of
flowers, &c., down to

Var. exilis. Slender, effusely paniculate: flowers nearly all on elongated almost
capillary peduncles: corolla only 3 to lines in length and of equal breadth of limb. —

412 SUPPLEMENT.

Common in S. California and east to Nevada: has mostly been referred to G. inconspicua,
var. sinuata, p. 148.

G. tenuiflora, Benrn., p. 147. Radical leaves often cottony-tomentose when young, soon
glabrate: calyx at most 2 lines long: corolla from half-inch to inch and a quarter long
(including the lobes); the slender tube dilated into the somewhat narrowly funnelform
throat. — S. California to S. Utah.

G. inconspicua, Douét., p. 148. The panicles or flowering branches when well developed
are rather rigidly erect, at least not effuse ; the lateral peduncles short and erect, at least in
fruit. The figures of Smith and of Hooker (from weak plants raised in England, and from
which Bentham has mainly drawn the character) do not very well represent the species,
although the whole tube of the small corolla is often thus included. Yet it is very commonly
more exserted (as in var. sinuata), even before the fructified ovary enlarges, but always sal-
verform, having a small and narrow throat, and limb only 2 to 4 lines in diameter. The
effusely-flowered plants with ampliate throat, which were included in var. sinwata, are now
taken for a small-flowered variety of G. latiflora. Apparently there are connecting forms
between all these species.

38. LOZSELIA, L. — Flowers involucrate or involucellate; both bracts and
calyx wholly or mainly scarious. Corolla funnelform, either regular or one or
two sinuses deeper. Seeds winged or margined, the surface becoming mucilagi-
nous when wetted.— Suffruticose, rarely annual, with spinulose-toothed leaves.

L. glandulosa, Don. Low, merely suffrutescent, roughish-pubescent with short and partly
gland-tipped hairs: leaves mainly alternate, short-petioled or subsessile, lanceolate or nar-
rowly oblong, those next the 1-2-flowered clusters similar but small, few-toothed, not scarious
nor reticulated, nearly enclosing the involucre of wholly scarious oblong-lanceolate almost
entire bracts: corolla violet or bluish, 6 or 8 lines long: filaments more or less declined-
incurved: seeds broadly winged. — Syst. iv. 248; Benth. in DC, Prodr. ix. 319, in part (i. e.

obconical throat and ovate acuminate lobes !— Bot. Gazette, vi. 217. — Highest slopes of the
Pinos Altos Mountains, New Mexico, Greene.

P. pectindétum, Greene. Glabrous and glandless up to the minutely glandular and pu-
bescent inflorescence: leaflets very narrowly linear, hardly wider than the rhachis: corolla
probably white: otherwise not unlike narrow-leaved P. foliosissimum, of which it may be an
extreme variety. — Bull. Calif. Acad. i. 10.— Eastern part of Washington Terr., L. W.

— A wholly peculiar species of this section is the following : —

P. pachyphylla, Gray. Stout, a foot or less high, with widely spreading branches, pu-
besvent and very viscid: leaves thick, large (inch or two in diameter), roundish and subcor-

the Sierra Madre of Los Angeles Co. by son of J. C. Nevin, 1884.

13. ERIODICTYON, Benth. P. 175, 176, add: —

EB. sessilifélium, Greener. Very leafy: pubescence partly villous and hirsute: leaves ob-
long or upper ones lanceolate, all closely sessile by a broad and truncate or subcordate base,
acutely and closely dentate (in age becoming glabrate and glutinous above): otherwise
nearly like the /. crassifolium form of EF. tomentosum. — Bull. Calif. Acad. i. 201. — Guada-
lupe Caiion, and elsewhere in Lower California, not far below the U. S. boundary to All
Saints’ Bay, Parry, Orcutt, and recently Greene. The seeds (with delicate stria and trans-
verse reticulation) appear to be quite alike, as far as seen, in all the species and forms, which
are very difficult to define.

E. tomentésum, Bentn., p. 176, is founded on a plant with pannose tomentum and no
villous or hirsute pubescence until the inflorescence is reached, such as Greene in Bull.
Calif. Acad. 1. c., describes from Monterey Co., but with the corollas seemingly in the same
imperfectly developed or deformed condition which Bentham had in his £. crass/folium, in

420 SUPPLEMENT.

this state “hardly surpassing the calyx (2 lines long),” and its lobes “very small, erect-
spreading.” But well-developed flowers of EF. crassifolium we know to be even half an inch
long and much surpassing the calyx. On Santa Catalina, Lyon got a narrower-leaved
form of the true /. tomentosum, with finer tomentum not pannose on the stem, and normally
developed salverform corollas.

A multitude of forms from Lower and.Southern California (including EF. angustifolium,
var. pubens, Gray, Proc. Am. Acad. xvii. 224), with and without villous or hirsute inflores-
cence, now connect /. angustifolium with E. glutinosum. This extends northward to Oregon,
coll. Howell.

BORRAGINACEX.

The following changes in the synopsis of the genera are, for brevity and con-
venience, based on the North American representatives.

== Glochidiate-armed: corolla short, with fornicate throat: calyx spreading or reflexed in fruit.

9. CYNOGLOSSUM. Nutlets horizontally radiate or barely ascending, much produced
below the high ventral insertion upon the low gynobase, on separation each pendulous by a
portion of the style which is torn away from below upward.

10. ECHINOSPERMUM. Nutlets erect or much ascending; the insertion supra-basal,
central, or from the inside of base to apex.
== = Not glochidiate, nor with loose or fleshy pericarp.
a. Corolla short, white or blue (only in an anomalous species elongated and yellow), usually with
more or less fornicate throat.

nearly horizontal), with depressed or truncate-complanate back bordered by an acute mar-
gin or an at length revolute (entire or dentate or spinulose) wing: scar short, from supra-
basal to supra-median.

111. KRYNITZKIA. Nutlets erect and straight, with wing or border, if any, unarmed and
plane, with introrse-basal or also ventral attachment from the base upward, the scar or
groove of attachment wholly naked. Fructiferous calyx erect or little spreading. (Includes
also no. 14, p. 179.)

12. PLAGIOBOTHRYS. Nutlets crustaceous or rarely coriaceous, ovate or trigonous,
oblique or incurved, and often incumbent over the low gynobase, to the depressed areola of
which they are attached by a median and either perforated or solid (sessile or short stipi-
tate) false caruncle.

13. ECHIDIOCARYA. Nutlets ovate-pyramidal, with ventral keel produced at base into
a conspicuous indurated stipe; the stipes united in pairs below and inserted by a common

branaceous and veiny fructiferous calyx, has sparingly appeared in waste grounds around New
York and Philadelphia, and at the red pipestone quarry in Minnesota.
CérpiA Grieert, Torr., p. 180, remarkable for its large flowers and small leaves, has been
found by Pringle not far below the boundary in Sonora, near the Gulf of California. .

ovate dorsal disk, but these shorter than the flattened subulate and sometimes confluent ones of
the margin: leaves usually lanceolate.

EB. diffasum, Leno. (not of p. 189). Soft-pubescent, or at most soft-hirsute (occasionally
some papillosities on the leaves): corolla bright blue, varying to white, one-third to two-

12. PLAGIOBOTHRYS, Fischer & Meyer, extended. (ITXaytos, side-
ways, Pdbpos, pit or hollow; so the name should have been written Plagéo-
bothrus.) — Western American annuals, low, commonly diffuse, with small and
short-pedicellate or subsessile flowers ; the short corolla white: nutlets rugose or
roughened, rarely smooth, ventrally carinate above the insertion, which is median
or supra-basal, or rarely supra-median, only one or two commonly maturing, and
then succumbent-horizontal upon the globular or depressed gynobase, tardily
detached, leaving a kind of caruncle at the insertion (either projecting and solid
or else annular and hollow), and corresponding depressed coneayities on the gyno-
base. — Gray, Proc. Am. Acad. xx. 281. Plagiobothrys, Fischer & Meyer, Ind.

§ 1. Ambiguous species: gynobase ovate-pyramidal, commonly bearing all
four nutlets, and when they are detached deeply 4-sulcate, or as it were 4-lobed

ovate-oblong or narrower depressions: nutlets tuberculate-roughened, incurved,
carinate on the back ; the caruncle longitudinal, narrow, and confluent with the
ventral keel above: coarse and comparatively robust plants, erect or merely
spreading, 8 or 10 inches high, unusually hispid for the genus; the inflorescence

§ 2. Genuine species: gynobase subglobose or merely convex, with ordicular
depressions left by the fall of the nutlets: these crustaceous or nearly so, very
seldom more than one or two ripening, therefore horizontally incumbent at
maturity, the caruncle short and broad, not stipitiform: slender or diffuse plants,

little or not at all hispid, or papillose-hispidulous on some of the lower leaves:
small-flowered.

* Typical, with an annular caruncle merely bordering a deep circular excavation, which is a kind
of false umbilicus: this suggested the name for the genus.

P. ruféscens, Fiscuer & Meyer, 1. c. Often a foot high, with slender stems from the tuft
of spatulate-lanceolate radical leaves, only the young hirsute pubescence of the inflorescence
and calyx rufescent: spikes elongated and sparsely flowered at maturity, naked, or with a

* %* Solid-carunculate, that is, the caruncle of the more incurved and ventrally concave nutlets
forming a broadish (commonly transverse) wen-shaped or short tougue-shaped caruncle: gyno-
base small and depressed.

+— Mature nutlets abruptly contracted at base and apex, so as to become cruciately 4-lobed,
vitreous-crustaceous and more or less lucid, transversely lineate-rugose on the back with straight
and broadish wrinkles separated by very narrow impressed lines, and running from the low
median crest to the somewhat crested margins: calyx deeply 5-cleft, persistent, or at length im-
perfectly circumscissile; lobes broadly lanceolate, villous with rufescent or soon pale or fulvous
pubescence: plants small and erect, a span high or little more.

P. tenéllus, Gray, 1. ¢., is Eritrichium tenellum, p. 192, with syn. and habitat. Nutlets a

paper, depressed and tufted, very leafy, hirsute and hispid with short bristles: leaves short,
spatulate or upper lanceolate ; uppermost oblong, accompanying the clustered or at length
more scattered flowers and equalling or surpassing them: corolla very small, hardly exceed-
ing the calyx: lobes of the latter in fruit only a line long, lanceolate: nutlets delicately

i. e. between the middle and the apex, ovoid, obliquely incumbent, little obcom-
pressed but rather turgid, nearly straight, rounded laterally, neither rugose nor
muricate, ventrally carinate only above the round scar, which is attached to the
depressed gynobase by a small and soft (when dry rather fragile) false caruncle :

pubescence : leaves spatulate-linear: spikes of the inflorescence when evolute dense, bract-
less: flowers nearly sessile: calyx with spatulate-linear segments as long as the white
corolla, in fruit appressed to the axis, accrescent, upper portion foliaceous, the base indu-

capillacea, Don, Syst. iv. 267. Takes the place of the preoccupied name J. muricata,
Cay., p. 214. J. armata, Reem. & Schult., is still earlier, but is obviously false. The genuine

such slender divisions as to justify the present specific name, and peduncles hardly longer
than the calyx. The commonest form in Mexico, extending to Venezuela: in Arizona

CONVOLVULACE. 435

Convotvutus SuerMrpt, Pursh, FI. ii. 730, does not belong to our flora. It was founded
on an incomplete fruiting specimen, West Indian (not from “Carolina’’), of C. micranthus,
Rem. & Schult. Vide Proc. Am. Acad. 1. c.

In the first edition the character of § CatysreGia has “stigmas very flat”: but in living
plants, those of C. sepium are thick, papillose, hardly flattish, or even terete, as some authors
have stated. But they are soft and flatter in drying. As a genus Calystegia entirely fails in
North America, as is seen in a series of species which now, with better material, are here

reconstructed.
C. sépium, L., var. Americanus, p. 215. Stigmas in dried specimens from broadly
oval (as in the Old World) to narrowly oblong: flower always solitary. — Here doubtless

C. Maximiliani, Nees, Pl. Neuwied Tray. 17. — Extends to the Pacific coast in Oregon and
California. Some of it has been referred to C. occidentalis.

C. macrostégius, Greenr. Like C. sepium, but “suffrutescent” and large (leaves 4
inches long and little narrower): peduncles 6 to 8 inches Jong, bearing 2 or 3 flowers within
the ample (inch or more long) bracts, and lateral flowers similarly bracteate : corolla short
and broad, cream-color (or “pale yellow,” Greene): stigmas rather broadly linear.— Bull.
Calif. Acad. i. 208. ©. occidentalis, Watson, Proc. Am. Acad. xi. 118. — The original is of
Guadalupe Island, off Lower California, Palmer. Also San Clemente, off San Diego, Lower
California, Nevin & Lyon.

C. Calif6rnicus, Cuorsy, p. 215. This depressed and never twining species extends to
the coast ranges of Oregon (Howell, Henderson) in a glabrous form, some flowers with
broader stigmas, bearing a certain likeness to C. Soldanella.

C. villosus, Gray, p. 216. Not at all or only feebly twining: the tomentose bracts to the
flower, although more commonly entire and erect, are occasionally, in the most white-vel-
vety plants, one or both of them, hastate and short-petioled, so passing directly into

Var. fulcratus. Greener, the soft pubescence short and fine: leaves either broadly
hastate (as in the type) or narrow and more sagittate; the bracteal pair similar but small,
either a little below the flower, or at the base of the calyx, occasionally one or both of them
entire: corolla (according to Cooper) pale yellow, probably only cream-color: stigmas
linear. — C. /uteolus, var. fulcratus, Gray, p. 216, and the only C. luteolus of which there
is good evidence of yellow or yellowish corolla! C. fulcratus, Greene, Bull. Calif.
Acad. i. 208.

C. occidentalis, Gray, p. 215. Character needs emendation only in reference to the ex-
treme variability of the bracts: these either Calystegia-like and covering (but rarely sur-
passing) the calyx, or variously smaller and shorter, or lanceolate or linear and more
foliaceous in texture, then at a little distance below the calyx, always in a pair, except on
the 2-3-flowered peduncles, when they may be disjoined. Whenever, as in the original of the
species, there is more than a single flower, the bracts are small and narrow. Specimens with
solitary flower and ample bracts referred here belong to C. sepium. Generally herbaceous or
with barely suffrutescent base, but Mr. Greene finds stems woody to a considerable height.
The form with diminished bracts is C. luteolus, Gray, p. 216 (excl. var.), but everywhere
with white corolla, or roseate in fading. So that this last name happily disappears.

Var. tenuissimus, Gray, p. 215. The commoner form, throughout S. California, in
the drier regions usually reaching only a foot or a yard in height: leaves from lanceolate- to
linear- or even filiform-hastate: bracts Calystegia-like, either acuminate and surpassing the
calyx, or oblong and barely equalling it. This may pass into

C. léngipes, Warson, p. 217, which was described from mere branches. It has no bracts,
the uppermost reduced subulate leaves are scattered and always alternate.

C. Havanénsis, Jace. Suffruticose, prostrate or feebly twining, canescently puberulent
and glabrate: leaves thick, oblong-lanceolate or elliptical, sometimes orbicular, obtuse or re-
tuse and mucronate, entire (6 to 12 lines long), abruptly contracted into a short petiole :

5. BREWEBRIA, R. Br.

The first division, containing B. ovalifolia, p. 217, which is probably large-flowered, needs
slight alteration, as to length of peduncle, for the following related and remarkable species.

B. grandiflora, Gray. Minutely sericeous-puberulent : root tuberous: stems procumbent,
2 or 3 feet long: leaves broadly oval or some orbicular, an inch or two long, very short-
petioled: peduncles rather shorter than the leaf, one-flowered, bearing two subulate bracts at
base of a stout pedieel: sepals broadly lanceolate, the two outer a little shorter than the
inner (these in fruit an inch long, surpassing the capsule): corolla funnelform from a rather
long tube, blue, 3 inches in length: styles capillary, distinct nearly to base: stigmas globose.

plant in herb. Sherard being Convolvulus micranthus and W. Indian.

6. EVOLVULUS, L. Next to #. Arizonicus, p. 218, add: —

EB. letus, Gray. Sericeous-canescent throughout, and with some soft villous pubescence,
much branched from a suffrutescent base, erect or barely spreading, 6 to 10 inches high,
leafy : leaves sessile, oblong-lanceolate, half-inch long: peduncles 1-3-flowered, surpassing
the leaves: corolla bright blue, with limb fully half-inch in diameter. — Proc. Am. Acad.
xvii. 288. — Mountains of S. Arizona, Pringle, Lemmon.

E. sericeus, Swartz, p. 218. The stouter varieties which prevail in W. Texas, Arizona,

SOLANACEA.

Wirnanta Mortsont, Dunal, p. 224. The original is W. somnifera, and Morison does not
say that he had it, but only something like it, from Virginia.

2. SOLANUM, Tourn.

S. Douglasii, Dunar (S. nigrum, var. Douglasii, p. 228), common through California and
in Arizona, and clearly indigenous, is a woody-stemmed perennial, and should rank as a

species.

6. CHAM ZSARACHA, Gray. Add to char.: Corolla with roundish
and tomentose twin elevations at the throat, alternate with the stamens.

C. Corénopus, p. 232. Corolla greenish-white (not “ yellowish ”), the appendages in the
throat large and protuberant.

SOLANACEA. 437

CHAMHSARACHA PHYSALOIDES, Greene, in Torr. Bull. ix. 122, is Physalis lobata, Torr.

BeEvLLINIA UMBELLATA, Roem. & Schult. (Saracha umbellata, Don; Gray, Proc. Am. Acad.
xix. 91),a common Mexican species, was collected by Lemmon in S. Arizona, on the Mexican
frontier, perhaps only adventive. The genus is known from the present and from Physalis by
the enlargement and rotate expansion of the fructiferous calyx under the berry into a membrana-
ceous 5-angled plate.

8. MARGARANTHUS, Schlecht. P. 237, add a second species, —

M. Lemmoni, Gray. Very much branched and decumbent, more leafy : leaves all quite
entire: calyx more deeply 5-dentate ; the teeth at length half the jength of the tube: corolla
white, campanulate-urceolate above the very short tube ; orifice obtusely 5-lobed. (It might
be Physalis minutiflora, Moc. & Sesse, but leaves not at all repand, as they are in M. solana-
ceus. — Proc. Am. Acad. xix. 91. — Cave Canon, 8. W. Arizona, Lemmon.

10. HVeLuM. l.

L. Richii, Gray, Proc. Am. Acad. v. 46. Name to take the place of the later L. Palmeri,
Gray, p. 238 (Proc. Am. Acad. vili. 292); abundant at All Saints’ Bay, Lower California.
L. quadrifidum, Dunal, founded on a rude figure, might be the same, except for larger size
and much shorter tube of corolla, so that it is with more probability referred to LZ. Carolinia-
num by Miers.

L. macrodon, Gray, p. 238. Rediscovered by Pringle, beyond the border of S. W.
Arizona, on the Altar River; has remarkably long and uarrow calyx-lobes, white corolla
tinged with green, and a very large hypogynous disk of a deep orange color.

L. Californicum, Nurr., p. 238. Distinguished by its fleshy leaves, and limb of the small
tetramerous corolla nearly as long as the tube. —Common on the coast of S. California from
Santa Monica to San Diego.

Var. Arizonicum. Leaves bright green, extremely fleshy, the small ones of the
fascicles on the branchlets pyriform or globular!— Desert of Arizona, Parry (imperfect
specimen was referred to LZ. parviflorum), at Lowell, Parish, and Maricopa, A. Gray.

L. parvifi6drum, Gray, p. 239. S. Arizona, Thurber, Pringle. May pass into L. barbino-
dum (which is not within our limits), but does not show the tomentulose nodes of the
fascicles.

L. Frem6onti, Gray, p. 239, is not uncommon in Arizona (coll. Parry, Vasey, &e.), and it
passes into the equally abundant

Var. gracilipes, L. gracilipes, Gray, p. 239, with pedicels from a third to half an inch
long, often quite as long as the flower. — 8. Arizona, Parish, Pringle, &e.

Other puberulent species, the first two more or less extra-limital, are : —

L. exsértum, Gray. Very much like the last preceding: leaves spatulate (not over half-
inch long): pedicels hardly half-inch long, about the length of the corolla: lobes of the
calyx acute, shorter than the tube: corolla-lobes very short, triangular-ovate, reflexed:
stamens much exserted. — Proc. Am. Acad. xx. 305.— Near Altar, in N. W. Sonora,
Pringle.

L. Pringlei, Gray, 1.¢. Cinereous-puberulent : branches slender: leaves spatulate and ob-
lanceolate (about quarter-inch long): pedicels 2 or 3 lines long: calyx with oblong and
obtuse foliaceous lobes equalling or longer than the tube and almost equalling the tube of the
corolla, which is barely 3 lines long, and longer than its own 5 roundish lobes: stamens
shorter than the corolla lobes ; filaments densely bearded at base. —In stream-beds, N. W.
Sonora, near the boundary, Pringle.

L. Parishii, Gray,1.c. Resembling the preceding, equally small-leaved and puberulent :
pedicels 2 or 3 lines long: corolla narrowly funnelform (5 lines long), thrice the length of
the obtusely and rather short-lobed calyx, with short 5-lobed limb; the lobes a line long,
ovate, obtuse, at length equalled by the stamens. — Mesas in the San Bernardino Valley,
S. California, Parish.

C. PArqut, L’Her., of Chili and Buenos Ayres, cultivated in many warm countries, appears
to have become spontaneous at San Antonio, Texas, coll. Dr. Ball, Palmer. Palmer’s plant is
C. multinervium, Watson, Proc. Am, Acad. xvii. 128: so probably is that of Dunal.

14. NICOTIANA, Tourn. Append to genus, on p. 243: —

N. Gravca, Granam. Arborescent, soft-woody below, glaucous and glabrous: leaves long-
petioled, ovate and subcordate, entire or repand : flowers loosely paniculate: corolla greenish
becoming yellow, inch or two long, tubular, contracted at throat, and with erect 5-crenate
limb not longer than the orifice. — Bot. Mag. t. 2837. — Native of Buenos Ayres, not rare in
cultivation, rather widely naturalized in 8. California and 8. Texas.

4. ANTIRRHINUM, Tourn.

A. virga, Gray, p. 252, is a perennial, the larger plants branched from the base and becom-
ing 6 or 7 feet high: corolla purple. Recently collected in Lake Co., Cleveland, Rattan.

The Californian species (of +- +), which are prehensile by lateral shoots acting as tendrils,
now augmented, may be defined as follows : —

A. Coulteria4num, Benrtn., p. 252. Marked by its truly spicate inflorescence, and com-
paratively large corolla, with very protuberant palate greatly exceeding the short upper lip.

A. Orcuttianum, Gray. Nearest the preceding, more slender, smaller-flowered, glabrous
up to the loosely spicate inflorescence, which is more disposed to bear tortile branchlets :
corolla about 4 lines long; lower lip not much larger than the upper: leaves linear or lower-
most spatulate-lanceolate: seeds tuberculate-favose.— Bot. Gazette, ix. 53.—Near San
Diego and adjacent Lower California, Orcutt.

A. Nevinianum, Gray, l.c. Much resembles the foregoing: seeds longitudinally cris-
tate-costate, as in A. Nuttallianum. — Los Angeles Co., at San Juan Capistrano, Nevin,
and near San Diego, Orcutt.

A. Nuttallidnum, Benrn., p. 253. Well marked by the scattered slender-pedicelled flow-
ers (with short comparatively eyual-lipped corolla not over 4 lines long), all subtended
by ovate leaves or leaf-like bracts, and principal leaves distinctly petiolate: seeds acutely
cristate-costate. Extends well into Arizona, &c.

A. subséssile, Gray. Erect and less diffuse than the foregoing, which it most resembles,
extremely glandular-viscid : flowers more racemose, longer than the pedicels or even sub-
sessile ; lower lip of corolla large in proportion : leaves ovate, all sessile or nearly so: seeds
of the preceding. — Bot. Gazette, ix. 53.— San Diego, &c., Cleveland, Orcutt, and Santa
Catalina Island, Schumacher. :

A. subcordatum, Gray. Of the group with flowers sessile or subsessile in the axils of
sessile leaves, and very unequal calyx, to which belong A. vagans and A. Brewer’: rather
large and stout, pubescent or below hirsute: lower leaves unknown ; upper closely sessile,
ovate, subcordate, thickish: flowers half-inch long: upper sepal large and oval, longer than
the rest, which are linear-lanceolate: corolla half-inch long, with ample throat and almost
equal lips, ochroleucous: longer filaments dilated at apex: seeds favose and the edges
of the pits muriculate. — Proc. Am. Acad. xx. 306. — Stony Creek, Colusa Co., California,

fully developed flowers. ‘The characters should be combined under the former and older
name. —In caiions, from N. W. Arizona to San Diego, where apparently it also pro-
duces small corollas.

A. speciésum, Gray, p. 354. Corolla has short or small, but not “narrow ” lips, and the
palate closes the throat; so that the character of the section needs correction. — Inhabits
also San Clemente Island, Nevin & Lyon.

A. janceum, Gray, p. 354. This is Saccularia Veatchii, Kellogg, Proc. Calif. Acad. ii. 17,

P. Cerrosensis (which should have been Cedrosensis), Kellogg, Proc. Calif. Acad. ii. 19, &
Bull. i. 145, with plate (see p. 273), from Cedros Island, off Lower California, proves to be a
good species, and P. brevilabris, Gray, Proc. Am. Acad. xvii. 229, is a synonym. Color of corolla
uncertain, but surely not “yellow.”

P. canoso-BARBATUM, Kellogg, has been identified by Mrs. Curran (in Bull. Calif. Acad. i.
145) with P. breviflorus, Lindl., and P. RostrirLorum with P. Bridgesii: but in the description
the color of the flowers of the two has been exchanged.

P. renetuus, Kellogg, Proc. Calif. Acad. i. 56, is by the same authority said to be P. azw
reus, Benth., probably depauperate.

Revised in the light of E. L. Greene’s new arrangement in Bull. Calif. Acad. i. 94-123

Bentham, Hooker, &c., in the Kew Herbarium. Polymorphous, but better retained entire under
five subgenera than divided into as many genera. uplacus is placed first, as having the best
claims to generic distinction, being shrubby.

§ 1. Diptacus, p. 275. Add char.: Capsule firm-coriaceous, narrow, sym-
metrical, tardily dehiscent down the upper suture, only after seed-shedding, also
later by the lower suture into the two placentiferous valves: yet in some plants
simultaneously dehiscent into the two valves. Seeds elongated-oblong. Pubes-
cence when developed partly of branching or somewhat aspergilliform downy
hairs.

M. glutinésus, Wenpt. Corolla from orange or salmon-color to pale buff. War. /inearis
is the most narrow-leaved form, in arid exposures, as Diplacus latifolius is the broader-

leaved and luxuriant extreme. Var. brachypus is the best-marked form, on account of the
villous (but deciduous) hairs of the calyx and generally pale corolla.

M. puniceus, Srevp. (D. glutinosus, var. puniceus, and part of var linearis, p. 275), com-
monly tall and narrow-leaved, with brick-red or blood-red rather than scarlet corolla, and
only in Southern California, may be regarded as a species until intermediate colors are
met with.

SCROPHULARIACE. 443

§ 2. Cinor, Gray. Corolla (with one exception) large for the plant, and with
a long-exserted and slender (even filiform) tube, expanded throat, and obscurely
bilabiate limb ; the lower lip sometimes small or obsolete : style pubescent above :
capsule cartilaginous, unequal-sided, sulcate at the dissepimental sutures, and
sharp-edged at the posterior dorsal one, enclosed at first in the narrow prismatic
and gibbous-based calyx, long persistent, indeed never detached, very tardily de-
hiscent, mainly by the posterior suture: placenta connate in the ovary but early
separating in the fruit: purple-flowered and low winter annuals, mostly blossom-
ing from near the root. -— (Pl. Hartw. 329) Bot. Calif. i. 563. Hunanus § Ginoe
and part of Hunanus proper, Greene, Bull. Calif. Acad. i. 98, 100.

* Capsule small and ovate or oblong-oval, much indurated: pygmy plants, flowering from the
ground and remaining very low, the stems in age seldom equalling or much longer than the
long-tubed (inch or two long) corollas, barely pubescent, neither glandular nor viscid, vernal.

M. tricolor, Linpt. Leaves mostly lanceolate: corolla (when well developed 2 inches
long) with ample somewhat regular limb; pink or lilac with a dark crimson blotch on each
of the rounded lobes, the 3 lobes of the lower lip about the length of the two-lobed upper ;
the throat yellow and brown-crimson, commonly spotted, open funnelform, about half the
length of the slender tube: anther-cells bearded at base: stigma of semi-orbicular and
slightly unequal lobes united by their edges at base: seeds very numerous, small, oblong, or
obovate-oblong minutely scaberulous, becoming smooth in age. — Common in the great
valley of California, especially on the Sacramento. To the synonymy on p. 274, add Lunanus
tricolor, Greene, l. c. 99. The former character of the fruit and seeds was taken from a
fruiting specimen of JZ. Douglasii, through mismatching.

M. angustatus. Exiguous, commonly acaulescent: Jeaves linear and linear-spatulate :
corvlla of the preceding species, except that the filiform tube is 4 to 8 times the length of
the short funnelform throat, and the lower lip rather shorter than the upper: lobes of the
stigma broadly cuneate: seeds (not here seen) according to Greene “few, large, favose-
pitted or favose-reticulate.” — M. tricolor, var. angustatus, Gray, 1.c. Eunanus angustatus,
Greene, 1. c. — Mountains of the northern part of California; first coll. by Bolander.

M. Douglasii, Gray. Leaves obovate or oblong: corolla with crimson-purple 2-lobed
upper lip forming the principal limb, the lower lip reduced to a truncate sinuately 3-crenate
border, or with a more conspicuous dentiform middle lobe ; the throat brown-purplish, rather
narrowly campanulate, about one third the length of the tube: capsule somewhat flattened
and with one very sharp-edged dorsal suture : seeds only 20 to 40 in each cell, comparatively
large, scurfy-muriculate, becoming smooth in age. — Part of M/. Douglasii, Gray, Proc. Am.

Mixed first by Bentham (in Pl. Hartw.) with the following species as to the flowering plant,
with which mature fruit of M. tricolor was distributed ; hence a confusion to which the Syn.
Fl. added, and also increased by taking fruit of M/. Douglasii for that of M. tricolor.

* % Capsule short-linear, at length arcuate: caulescent, flowering later and longer, viscidulous-
pubescent.
-+— With long-exserted filiform tube to the corolla, as of the section.

M. Kelléggii, Curran. Erect, a span or two or becoming a foot high, with internodes
longer than leaves: these ovate to obovate or spatulate-lanceolate: corolla crimson-purple ;
its tube inch long, expanding into a short-funnelform throat and oblique limb; short lobes
of lower lip only half the length of the upper and more spreading: stigma with ovate and
obtuse unequal lobes, or by their union obliquely peltate: capsule narrow, obtuse (4 or 5
lines long and a line thick), rather terete, moderately unequal-sided : seéds comparatively
few and large, obovate. — Curran in herb. Gray. M. Douglasii, partly, Gray, Bot. Calif., &c.,

+— +— Ambiguous species, with corolla of § Eunanus, and litile exserted, but with oblique late-
dehiscent capsule of § Gnoe.

M. latifolius, Gray, p. 274. Extralimital. The capsule in plant raised from Palmer’s
seeds appears to be only moderately oblique, linear-oblong, obtuse, and not indurated; but
as now received from Mr. Greene, from its native habitat, and fully mature, it is lanceolate,
strongly oblique, and as if bent on its broad base; the upper carpel much larger than the
other, very gibbous and sharp edged dorsally, and there very tardily dehiscent.

§ 3. Eundnvus, Gray, Bot. Calif. Corolla from tubular-funnelform to nearly
campanulate, with either obscurely or manifestly bilabiate limb, the proper tube
either moderately exserted or included in the campanulate or oblong calyx: style
glandular-pubescent above: stigma usually peltate-funnelform, obscurely 2-lobed
or entire: capsule symmetrical, from firm-chartaceous to membranaceous, dehis-
cent by both sutures into two valves, which bear the separated placente: low or
occasionally taller annuals, most of them glandular- or viscid-pubescent and
heavy-scented.

* Corolla only a quarter-inch long, slender, only slightly exserted out of the broad and ventricose
calyx until elevated on the growing capsule: valves thin-chartaceous.

M. Rattani, Gray. Viscid-pubescent, a span or two high: leaves oblong; upper about
equalling the sessile flowers: calyx very viscid, when fructiferous little higher than broad,
a little oblique at orifice, and with short ovate teeth: corolla rose-purple, its lobes barely a
line long, equal except that the upper are united to near the middle: capsule narrowly
ovate-lanceolate, nearly half exserted: seeds oblong-oval.— Proc. Am. Acad. xx. 307.

* * Corolla a quarter to three-fourths inch long, funnelform or narrower, well exserted beyond
the campanulate or oblong calyx: capsule-valves membranaceous or chartaceous: plants a span
or two high and branching when luxuriant, when depauperate dwarf and simple, beginning to
blossom from near the root.

+— Calyx not manifestly oblique at orifice, but lower teeth usually a little shorter. (Species of
difficult discrimination. )

M. mephiticus, Greene. Very viscid-pubescent and strong-scented: leaves from ob-
ovate-oblong to nearly linear: calyx-teeth short, broadly lanceolate, acutish : corolla half to
two-thirds inch long and with somewhat bilabiate limb 4 or 5 lines broad, bright yellow,
often purple-dotted in the throat, sometimes whole throat or even the limb turning reddish :
seeds oval. — Bull. Calif. Acad. i. 9. Eunanus mephiticus, Greene, Bull. Calif. Acad. i. 102.
— Common in the Sierra Nevada from the Yosemite northward.

M. nanus, Hook. & Ary. Puberulent and somewhat viscid, or low and early-flowering
plants almost glabrous: leaves obovate and spatulate-oblong, all with tapering base: calyx-
teeth broadly lanceolate or triangular, acutish or when outspread obtuse, but acute when
the tips are conduplicate, a quarter or a third the length of the oblong tube: corolla rose-
purple with darker or yellow throat, mostly two-thirds or three-fourths inch long ; the limb
half-inch or less wide, evidently bilabiate and the lower lip a little shorter than the upper:
seeds oval-oblong. — (Supra, p. 274, excl. the yellow-flowered form and the var.) California

M. Bigelovii, Gray, p. 274. Viscid-pubescent, sometimes viscidly villous: leaves nearly of
the preceding or more acute, the upper ovate and acuminate: calyx-teeth triangular and
acuminate or subulate-acute, about half the length of the tube: corolla crimson, sometimes
with a yellow eye, three-fourths inch long when well developed, narrow up to the abruptly

much dilated throat and expanded slightly bilabiate limb, this half to three-fourths inch in
diameter and rotately expanding: seeds oval to oblong. — Belongs mainly to the southern
and eastern parts of the Sierra Nevada, and extends from the borders of Arizona to the
interior of Washington Terr.

Var. ovatus. More rigid, a span to near a foot high, at length spicately flowered, all
the floral and even most of the lower cauline leaves ovate from a broad base, closely sessile,

teeth half the length of the tube: corolla with narrow tube (3 lines long) abruptly dilated
into the broadly obconical throat and seemingly regular spreading limb tie hee 4 lines
high), the latter “ yellow ” or probably nearly white, the throat dark purple in 8 or 10 lon-
gitudinal blotches. — MW. nanus, var. bicolor, Gray, p. 275. Eunanus bicolor, Gray, Proc. Am.

sierras in Fresno Co., by Brewer, in the Geological Survey under Whitney, whose name it
may bear.

M. Fremonti, Gray, p. 275. At length a span or two high, from glabrate to soft-villous or
tomentulose, not glandular and little viscid : leaves from narrowly oblong tospatulate or lan-
ceolate : calyx-teeth short and broadly triangular or ovate, obtuse to acutish : corolla crimson,
comparatively large, trumpet-shaped, being narrowly tubular-funnelform up to the abruptly
spreading almost regular limb, this half to three-fourths inch in diameter: seeds oval. —
Common only in Southern California. Parish finds a white-flowered variation.

+ + Calyx decidedly oblique at orifice, ovate in outline, at least in fruit, and strongly plicate-
angled: corolla narrow.

M. subsectindus. Viscid-pubescent, diffusely branched from the base, the at length
elongated branches bearing spicately disposed flowers chiefly turned to one side: leaves
oblong, short ; lower less than inch long, upper shorter than the ample (4 lines long and 3
broad) fruiting calyx: teeth of the latter all similar, deltoid-ovate, acute, about a line long:

M. ringens, L., extends northward to the Hudson’s Bay district. This and the allied
M. alatus are perennial by stoloniform rootstocks, produced rather late in the season. The
corolla is not really ringent, although the lips are widely open, for the throat is personately
closed.

The remaining Western species, i.e. all after MW. alatus, p. 276, are re-elaborated as fol-

lows : —

dark blotches or dots, or in a few rose-colored or dark crimson: seeds mostly smooth or with slight
reticulation or striation.

+— Filiform-scapigerous and stoloniferous perennial, the stolons often producing scaly bulblets
after the season's growth: scattered and long hairs viscous: leaves 3-nerved.

elongated corolla. — Af. moniliformis, in part (the villous- and more or less viscous-
pubescent plant), Greene, Bull. Calif. Acad. i. 119. Common especially in the Sierra
Nevada.

Var. sessilif6lius. Leaves all sessile on upright or ascending stems (these some-
times a foot or two high, very slimy), but those on decumbent shoots from the rootstocks
of the same plant not rarely well-petioled.— M. cnodorus, Greene, 1. ¢., but the plant as
strongly musk-scented as the ordinary species, at least in some cases. — Not rare in wet
places, from San Bernardino Co., California, northward, and passing into the ordinary form
in Oregon. Calyx-teeth in all the forms variable in length and width.

+ + + Leafy-stemmed and slender, perennial by filiform rootstocks, scentless, the minute
pubescence (if any) not viscous: leaves essentially pinnately veined, the peduncles seldom sur-
passing them: calyx-teeth acute, rather narrow and little unequal: corolla open, about inch
long: capsule acute, not stipitate-contracted at base.

M. moniliférmis, Greene, in part. Filiform rootstocks ending in small moniliform
tubers: stems a span or two high, simple and erect or with spreading branches: leaves ovate

+ + + + Leafy-stemmed, perennial by stoloniferous or creeping basal branches, or sometimes
by filiform rootstocks, but seedlings flowering the first year, and precocious depauperate ones
dying at maturity of fruit, glabrous or sometimes minutely pubescent (but never clammy-hairy

else the apex nodding: calyx at least in fruit oblique-sided and more or less inflated, also oblique
at orifice; the teeth all obtuse and broad (sometimes mucronulate, but never acute except when
folded); uppermost targer ; lower turned upward toward the upper at maturity of fruit: corolla
more or less personate: capsule obtuse or retuse, mostly contracted or short-stipitate at base.

4+ Small-flowered for the size of the leaves and (leafy) branches; the light yellow corolla (at most
half-inch long) not twice the length of the calyx: capsule short-oval, very obtuse or retuse.

M. glabratus, HBK. Diffuse or ascending from a creeping base : stems somewhat quad-
rangular: leaves round-oval or ovate, mostly denticulate or dentate; lower with margined

syn. M. dentatus, Nutt. (which see above); and also M. cupreus, Regel (M. luteus, var.
cuprea, Hook. Bot. Mag.), which belongs to a distinct Chilian species. The original Chilian
M. luteus, as Bentham decided, although usually distinguishable, cannot be specifically sena-
rated from the Northern coast form, M/. guttatus, DC. Cat., and of Greene, 1. c., &c., to which
pertain M. luteus, Bot. Mag. t. 1501, Bot. Rep. t. 661, and Jacq. f. Ecl. t. 92. The slender
shoots from the base of the stem either root and form stolons, or not rarely rise and bear
small leaves and flowers.

Var. alpinus, Gray, p. 277 (excl. syn. as above). Includes a series of mountain
forms, varying from two inches to near a foot high, clearly perennial, proportionally large-
flowered. Small forms with round and nearly entire leaves answer exactly to A/. Tilingii,
Regel, Gartenfl. xviii. 321, t. 631, plants of which, from the same sowing, developed next
year into the typical N. American species, shown in xix. 290, t. 665; also in the gardens
under this name and as ‘“ J/. Rezli,” the latter answering to J/. Tilingii, Greene, 1. ¢., from
near Summit Station.

Var. depauperatus, Gray, 1c. partly. I. microphyllus, Benth.! in DC. Growing
with the larger or ordinary plants, evidently an extreme depauperate form, either seedling
or showing the creeping stolons ; with filiform stem 2 to 7 inches high, 1-4-flowered; leaves
a quarter-inch or so long, and corolla 6 or 7 lines long. Grows with the larger forms on
Columbia River: specimens exactly like those of Douglas from same district (except that
some show the stoloniferous base) were received from Mrs. Barrett.

M. Scotleri, Hook. Erect, from a stoloniferous base, a foot or two high: leaves thick,
very smooth and shining, oblong-lanceolate (an inch or two long, 4 to 6 lines wide), obtuse,
evenly callous-denticulate ; lower tapering into petioles of equal length; floral ones short
and small, ovate and amplexicaul: flowers apparently of the preceding, but corolla shorter.
— FI. ii. 100; Benth. in DC. 1. ¢.--On the Columbia River, Scouler, in fruit only. Now
rediscovered, in flower, in the mud on the south shore of the river (sometimes covered at

station.

+ + + + + Pure annuals, leafy-stemmed, various in habit and size: no mucilaginous-
clammy hairs: seeds oval or oblong, mostly with a smooth close coat.

a+ Comparatively large-flowered, the yellow corolla inch long and.broad: upper cauline leaves
connate into orbicular disks, glaucous: calyx less oblique than in succeeding.

M. glaucéscens, Greene. Erect, often tall, glabrous and glaucous, except the radical
and lower cauline leaves, which are sometimes villous-pubescent ; these cordate-orbicular,
crenate-dentate or incised, sometimes almost lyrate, slender-petioled ; the perfoliate disks
denticulate or entire: inflorescence at length racemiform: corolla with ample throat: style
minutely pubescent: calyx campanulate, slightly arachnoid-villous at the throat within,
appearing repand-truncate, the teeth being very short and broad, in fruit nodding on the
ascending peduncles, the two lower teeth incurving in the manner of the following. — Bull.
Calif. Acad. i. 113. — California, along streams in the foot-hills of the Sierra Nevada, from
Lassen to Butte Co., Fremont, Mrs. Austin, A. Gray.
++ ++ Middle-sized to small-flowered (even in same species): herbage not glaucous: corolla yel-

low: calyx especially when fructiferous and ventricose oblique-sided and oblique at orifice,

strongly plaited-angled, mostly with acute or acutish teeth, the lower at maturity turned toward
the larger uppermost: fructiferous peduncles mostly spreading or the apex nodding: capsule
distinctly short-stipitate.

BIGNONIACEA.

3. CATALPA, Scop. Two North American species are now distinguished,
not very definitely, viz.: —

C. bignonioides, Watr., p. 319. Low and much-branched tree, with thin bark: leaves
(unpleasantly scented) moderately acuminate, and not rarely a pair of lateral salient teeth :
corolla hardly inch and a half long, thickly spotted within, the tube campanulate, limb
oblique, lower lobe entire: capsule very slender. — Exclude from the syn. the figure in
Duhamel. —$. W. Georgia, Alabama, &c.;, and widely cultivated.

C. speciosa, Warper. Large and tall tree, with thick bark: leaves (inodorous) candate-
acuminate: corolla larger (2 inches high), nearly white, inconspicuously spotted, and with
broader little oblique limb, the tube obconical, lower lobe emarginate: capsule equally long
but nearly twice as thick: flowering earlier (May). — Engelm. Bot. Gazette, v. 1; Sargent,
Forest Trees, 10th Census, 115. C. cordifolia, “Jaume” in Duham. ed. nov. ii. t. 5, as to
the plate. — S. Illinois and adjacent States. A more showy as well as larger and more yal-
uable tree. First discriminated by the late Dr. J. A. Warder, and scientifically published by
Engelmann under Dr. Warder’s name.

Crescéntia cucursiTina, L. (see p. 320), was collected by the late Dr. Garber in S. Flor-
ida: probably not indigenous.

ACANTHACE.
3. CALOPHANES, Don.

C. oblongifolia, Dov, p. 324. The sepals much surpass the capsule, and sometimes nearly
equal the corolla. The var. angusta should give place to

C. angtsta. A span or two high, erect or ascending from a creeping base, only minutely
puberulent, usually very leafy: leaves half to three-fourths inch long, from oblong to al-
most linear, obscurely veined: flower small: corolla barely half-inch long, rather narrow:
sepals distinct to near the base, subulate-setaceous, hardly surpassing the capsule. — C. ob-

ACANTHACEA. 457

8. ANISACANTHUS, Nees. Species rearranged, as follows: —

x Calyx-lobes attenuate, longer than the stipe and mostly about equalling the body of the capsule
(a third to half an inch levg): corolla dull red, funnelform above, with lobes much shorter than
the tubular portion: flowers distinetly pedicellate, chiefly in axillary and mostly leafy fascicles.

A. Thurberi, Gray, p. 328. From mountains of W. Texas (Havard) to those of S. W.
Arizona, Pringle, Parish, &c. Here belong the U. 8. portion of Drejera puberula, Torr.,
and A. pumilus, p. 328, not Nees.

* %* Calyx shorter, not surpassing and only in A. virgularis ever equalling the stipe of the
capsule: flowers usually, at least the upper ones, spicately or racemosely disposed along the
branchlets and secund, the upper subtending leaves reduced to subulate bracts.

A. insignis. Puberulent or nearly glabrous: leaves mostly linear-lanceolate to linear :
flowers pedicellate, in lateral clusters from axils of fallen leaves and short-racemose on
evolute small-bracted branchlets: calyx puberulent-glandular ; the almost distinct sepals
linear-subulate, 2 or 3 lines long: corolla rose-red or even salmon-color, 2 inches long; the
linear lobes shorter than the upwardly enlarged tubular portion: stipe when well developed
longer than the body of the capsule. — A. pumilus, Watson, Proc. Am. Acad. xviii. 133.
Drejera puberula, Torr. Bot. Mex. Bound. 123, as to pl. Gregg. — Chisos Mountains on the
border of W. Texas, //avard, a linear-leaved form, with stipe to capsule a third of an inch
long. (Adj. Mex. Between Parras and Chihuahua, Gregg. Palmer, with stipe as long as
capsule, and in the State of Chihuahua, Pringle, with stipe half-inch long.)

A. Wrightii, Gray, p. 328. Calyx glabrous or nearly so, remarkably short, barely 2 lines
long, and the lobes rather obtuse, seldom half the length of the stipe: corolla with throat
very little dilated.

A. pUmitus, Nees, Hemsl. Biol. Centr.-Am. Bot. ii. 522, includes A. Greggii, p. 328, and
has tomentulose-pubescent and short calyx, the scarlet-red corolla of the next, but with its
ligulate-linear lobes longer than the narrow tube.

A. vireuLdAris, Nees, has a nearly glabrous calyx with slender-subulate lobes, a scarlet-red
corolla with lobes shorter than the slender tube, and stipe shorter or not longer than the body
of the capsule. To this belongs the plant of Berlandier referred to Drejera puberula, Torr.
Also the A. pumilus, Girst. Pl, Liebm. Palmer’s Mexican no. 1016 has the leaves and corolla
of the most narrow-leaved A. virgularis, but the calyx of A. Wrightii. A. junceus, Hemsl., the
Drejera juncea, Torr. 1. ¢., is founded on a leafless branch of a slender and junciform A. vir-
gularis, like one recently collected in Chihuahua by, Pringle.

12. DIANTHERA, Gronov. At end of the genus, p. 330, add: —

JacopwiN1a NEGLECTA, Sericographis neglecta, Oersted, a native of the Mexican coast-region,
has been received, through P. J. Berckmans, in living specimens from Florida, where it is said
to be spontaneous, — probably through some mistake. It is somewhat shrubby, with oblong-
lanceolate or broader and acuminate leaves, flowers (inch and a half long) secund, in naked
triple spikes on a slender axillary peduncle: calyx and bracts short: corolla light brick-red
and narrowly tubular: connective of the anthers broad enough to refer the plant to Dianthera,
the slightly higher and larger cell (or rather the connective) apiculate.

15. DICLIPTERA, Juss.

D. resupinata, Juss., p. 331, covers two species. The true one is annual, with a loosely
branched stem: leaves from ovate to oblong-lanceolate, rather long-petioled: involucral
bracts cordate-rotund: seeds muricate with subulate minutely setuliferous processes, —

D. pseudoverticillaris, Gray. Intermediate between the Platystegie and the Spheno-
stegie, annual, a foot high, branching and flowering from the base, nearly glabrous: lower
leaves ovate, acuminate (over an inch long), long-petioled; upper much smaller, ovate-
elliptical, short-petioled, equalling the axillary subsessile leaf-like involucral bracts: these
at first spreading, deltoid-roundish, very obtuse or retuse, rarely mucronulate, abruptly con-
tracted at base, there commonly coalescent into a narrow cup: corolla not surpassing the
involucre:; seeds muricate with minutely setuliferous processes. — Proc. Am. Acad. xx. 308.

cicles of leaves: these remarkably small.

C. brachyanthum. Slender, very much branched, puberulent : branchlets quadrangular :
leaves from linear-spatulate to obovate, quarter to half inch long, veinless, subsessile ; pri-
mary ones articulated (in the manner of the genus) with the pulvinus or very short persistent
petiole, which after their fall often becomes spinescent (but. barely a line long): calyx

26. ACANTHOMINTHA, Gray. A second species, with similar aspect
and bracteal leaves, differs remarkably in the flowers, most so in the upper lip of
the corolla. ‘The shorter and smaller lower lip of the calyx in both species is
erect and appressed to the upper in fruit.

A. ilicifélia, Gray, p. 365. Add: Cusps of the oblong calyx short, not longer than the
