nin NEAR THE THIRTY-FIFTH PARALLEL, “ExrLonn BY LIEUTENANT A Wz WHIPPLE, TOPO- — GRAPHICAL, ENGINEERS, ca 2. a INTRODUCTION. The greater part of the botanical collections made by Dr. J. M. Bigelow, in the Pacific Railroad Survey, under the charge of Captain Whipple, were submitted to me for examination, in accordance with the instructions of the War Department. The plants that were collected before reaching Fort Smith, on the western borders of Arkansas, are of comparatively little interest, and are not included in the following list. The surveying party, in proceeding from Fort Smith to Albuquerque, travelled near the Canadian river, through the Indian territory and northern Texas ; thence through northeastern New Mexico to the Rio Grande. This river was crossed on the 10th of November, at which time the flowering season of most plants had passed ; and the explorations continued through western New Mexico, chiefly between the parallels of 35° and 36°, to the Great Colorado, which was reached on the 28th of February. The most interesting region of this part of the route is the valley of Williams’ river, (com- monly called Bill Williams’ Fork,) a tributary of the Colorado. Some of the most remarkable plants of the collection were found here, and it is a matter of regret that a country so rich and peculiar in its Flora (and I am informed by Professor Baird that its Fauna is equally remark- able) was not visited at a more favorable season. From the Colorado the route was across the California desert to the Cajon Pass, in the southern part of the Sierra Nevada ; thence through Coco Mungo and Los Angeles to San Pedro, on the Pacific coast. Here the surveys of Captain Whipple terminated ; but Dr. Bigelow remained in California until near the first of June, and improved the time in exploring considerable portions of the valleys of the Sacramento and San Joaquin, as well as numerous tributaries of those rivers. His ample collections were brought home in perfect order, and the following report affords abundant proof of the zeal and success with which he labored. A number of new genera, and more than sixty new species, have been discovered by Dr. Bigelow, and he has added much valuable information upon many heretofore imperfectly known plants. . The observations of Dr. Bigelow upon the geographical botany of the regions explored are Entoresting. and are embodied by him in a separate eee, 4 as ers are his notes upon the more — antetisting forest trees of the country. ~The Cactacez collected in the Expedition have been elabotiated conjoint by Dr. Engelmann and Dr. Bigelow, and are described by them in a separate portion of Captain Whipple’s report. The Composite and Scrophulariaceze were described by my friend Dr. Gray, to whom I am indebted also for much valuable aid in drawing up this catalogue, as will be seen by the fre- | quent quotation of his manuscript names in the following pages. The drawings were, with few exceptions, executed by Sprague and Riocreux, two of the most skilful botanical artists now living. All the engraving has been done upon stone by Prestele, who excels in this branch of the art. 2 JOHN TORREY. Naw York, January 12, 1857, ERRATA AND ALTERATIONS. Owing to the distance of the author from the press, and the rapidity with which the work was printed, the revised sheets could not be examined, so that many typographical errors have been left uncorrected. The more important of these are noticed in the following list, but some others have doubtless been overlooked. The mistakes of punctuation are numerous, but they do not materially affect the sense, and they have not been included in the errata.

The general botanical sketch and that of the forest trees of Captain Whipple's survey were written immediately after ome return from California, and before any elaboration, or even a cursory examination, of the botanical collections had been Soon after our return, the collections, with the exception of the Cactacex, were placed in the hands of my excellent Shind Deets r Torrey, of New York. The Cactacex were not examined until the spring of 1855, illness and the obstructions to travel preventing my visiting St. Louis during the winter; a my report was made and printed before the memoir on Cactacee was prepared, a fact which will account for many discrepancies between the two. These notes are appended for the purpose of making the necessary corrections. the ough my name is associated with that of my highly esteemed friend Doctor Englemann, in the elaboration of the collections in Cactacez, justice requires that I should state that the diagnoses of all the new species are to be accredited to him 2. ‘‘ First appearance of atom ie A ERIOPODA, BouTELOUA cuya, AND Bouretova nimsvta, under the general term of “‘ grama ~ se abound n the plains from about the Peston to shat the 113th degrees of agile.

As an instance of the difficulties Tien the study of this interesting family of plants, I will here quote from a letter beet received from my friend A was associated with me on the Boundary Commissi Under date of July 31, ae he writes: ‘‘Since I sent you the letter press copy, (Cactacew of the Boundary, by De Sivireaets) I have made a new discovery, which separates a cated Cereus from Cereus cespitosus. It is on a living specimen which I brought on my last trip, from near Escondida gs (El Paso road,) and which, eae produced from ten flower buds six perfect blossoms, so decidedly different te those of C. cespitosus that I gave a minute account of it to Dr. Engelmann. Amon ng the collections of your living specimens in Wathington, tied re are two or three individuals very similar, if not identical, with my new one, but also different in habits from the white-spined true C. cxspitosus, so that I hope we soon will be able to corroborate the fact by the study of more individuals. C. ceespitosus has short farinaceous white spines, of a lax nature, whilst the spines of the new one are rigid, horny, yellowish translucent, adscendent, and recurved; the lower ones the petals, whence I have given it the name Cereus concotor. . cespitosus flowered for me almost at the same ti so that I a a aa opportunity to make close observations.

Mr. Schott, himself, passed it several times petal Mr. Wright passed it four several times, and Dr. Parry, an acute and discriminating collector of Cactacee, certainly passed it once. We all failed to detect it, while passing ‘ie locality, at two different seasons of the year. In boundary publication of Cactacea are six or seven pretty distinct species, besides the one under consideration, that in general habit and arrangement of spines would be taken as mere varieties, were it not for the beautiful permanent dis- tinctions presented by the flower and fruit, whi on are difficult to secure on wets surveys and government expeditions. ‘*The Cactacexw have not heretofore etn well studied in the United States,’’ page 2. owever well this observation might apply at the time my memoir was written, the patient labor and enlightened researches of Dr. Engelmann since uite that pe on the collections of the boundary commission, as well as Pacific railroad surveys and explorations, show qui a state of things now ; so that this will ccmpare favorably with any other department of 8. schon weap tide: " page 4, is probably Dasyiirion Texanvm, although, as Dr. Torrey thinks, it may be undescribed .

DESCRIPTION OF THE GENERAL BOTANICAL COLLECTIONS. BY JOHN TORREY. RANUNCULACE, CLEMATIS sertatcatiea Nutt. in Torr, & Gray, Fl. 1, p. 9. Near San Antonita, New Mexico ; October. In fru (CLEMATIS ame (sp. nov.): humilis? herbacea? glabella ; foliis pinnatis vel subbipin- - natis; foliolis 7-9 trilobis tripartitisve longiuscule petiolulatis, lobis subovatis integerrimis nunc incisis ; pedunculis solitariis unifloris; calyce subeampanulato, sepalis anguste oblongis haud crassis apice obtuso patentibus ; caudis caxpolloram dense plumosus. On the Sandia mountains, New Mexico; October. Ofthis apparently new Clematis there is only a single flowering specimen and a few mature carpels in the collection. The stem appears to be low and nearly herbaceous, but it probably elongates and climbs by the petioles. The leaflets are only from half an inch to an inch in length, membranaceous and inconspicuously veined ; those of the lower pinnz more divided. Peduncle an inch or two in length, nodding in flower. Sepals scarcely over half an inch in length, pale, membranaceous in the dried state, probably a little thickened in the living plant, but not leathery as in C. Viorna, C. Pitcheri, etc., almost glabrous, except the densely tomentose margin, not appendaged, but the obtuse tip spreading. Carpels silky pubescent, becoming glabrate ; the tails over an inch long, plumose as in C. Viorna. The flowers are_ smaller than in any other North American species of this division. TIS LASIANTHA. Nutt. in Torr. & Gray, Fl. 1,p.9. Hill sides, Napa valley, April 27. Only the male plant of this showy species was collected by Dr. Bigelow. The female was not known when the Flora of North America was published ; but it has since been found by Colonel Frémont. The carpels have tails of about an inch and a half in length.

Sides of rivulets, Napa valley, California, April 25, (withimmature fruit). It occurs in Coulter’s California collection, in flower only. Leaves mostly petiolate, ternately decompound : leaflets obovate and cuneate, incisely 3-lobed ; the lobes cut or entire. Panicle contracted, few-flowered. Sepals ovate, rather acute. Carpels 15-25, ovate, compressed, with two prominent ribs on each side. Stipoan linear, elongated. T. Fendleri has a more compound and spreading panicle than our plant, and the carpels are more or less glandular. THALIcTRUM Dioicum, Linn.; Torr. & Gray, Fl. 1, p. 38.

Differs from the ordinary form of A. nemorosa, in its tall stem (which is a foot or more below the involucre), the elongated petioles, and the pretty strong _ pubescence of the leaves. The leaflets are rhombic-ovate, incised and rather coarsely toothed, Re he but the lateral ones are not two-parted in any of the specimens. Such leaflets, however, occur now and then in the eastern A. nemorosa. Rey. Mr. Spalding found the same plant on the Kooskooskee, in Oregon, and it exists in Geyer’s collection.

This seems not to be the form or species which almost universally represents the section Batrachium in North America, but what is called R. aquatilis by those European authors, who do not subdivide the Linnean species extremely. It is a state destitute of emersed leaves. RANUNCULUS HEDERACEUS, Linn. var. With the preceding. Nearly the R. tripartitus, D.C., as to the leaves, etc. ; but the receptacle of the fruit is glabrous. The petals are oblong-obovate and twice the length of the calyx.

Not an uncommon species in the southern part of California, It is regarded by most of our botanists as a variety of R. parviflorus, which, indeed, it very much resembles. This species differs, however, it being much less hairy ; the tubes of the leaves are broader and less acute ; the fruit is decidedly tuberculate, while in R. hebecarpus it is merely a little roughened, and the - pubescence longer. In the latter the beak of the fruit is decidedly shorter than in the former.

In the memoir above quoted, Mr. Nuttall does not express any opinion as to the affinities of this genus, owing to the embryo being unknown, the seeds in all his specimens being imperfect; but he says that i it ‘may well form a Suborder Crossosomezx.”’ On the ticket of a fragment of this plant, which he sent us, he has written: Nat. Order Pwoniacew. Unfortunately, our specimens are only in flower, and the ripe seeds are still wanting. Although the stamens are decidedly perigynous, and the seeds are furnished with an ample fimbrillate arillus, the plant may never- theless belong to the tribe or Suborder Peeoniaceee. We were once inclined to refer it to tribe Spireee of Rosacez, to which it has some resemblance in the flowers; but it is destitute of _ stipules, and arillate seeds are not found in that order. We should place this remarkable plant in Dilleniacez, were it not for the perigynous stamens. These are inserted in several series into the upper part of a thin disk which, lining the tube of the calyx, projects in a somewhat tumid ugar around the base of the pistils: as in peas BERBERIDACE®.

Not very distinct from H. mutilum*, » A remarkable shrub, bearing mpe pods only, was found by Dr. Bigelow in western New Mexico, on the hills bordering Williams’ river, from near its source to its confluence with the Great Colorado. The Mexicans call it Canotia. It usua y grows from 9 to 10 feet high, but was sometimes found attaining the height of nearly 20 feet. The branches are very numerous, alternate, rigid, terete, of a greenish color, and terminate in very long thorns. The epidermis is smooth and finely striate. Between the elevated striae there are 2 or 3 rows of impressed perforations. There were no leaves on the plant when Dr scales appear to have been. The pedicles are somewhat racemose towards the summit of the branches. They are about half an inch long, somewhat spreading, then curved upward, and are articulated below the middle. Calyx persistent, 5-cleft, small, free from the ovary. The corolla, if any, is deciduous. Stamens 5, hypogynous ; filaments slender and distinct. The fruit is nearly an inch long, oblong, acute at each end, and pointed with a short persistent subulate style, covered with a thin red flesh; the endocarp ligneous ; 5-celled, septicidally dehiscent about two-thirds of the way down, and loculicidally at the summit, which thus presents 10 subulate points in pairs.. Seed solitary in each cell, suspended f; the summit at the i gle, obleng, compressed with a broad somewhat falcate wing at the inferior extremity. Testa coreaceo-chartaceous, dull, minutely granu~ lated. Albumen very thin. Embryo nearly the length of the seed ; cotyledons thin and flat. Radical inferior, terete, short, straight. We can scarcely form a conjecture.as to the affinities of thi plant, but may note that the fruit is not unlike that of Eucryphia, which Lindley, following Choisy, refers to Hypericacee, nothwithstanding its superior radicle. The fruit has the same thin fleshy covering that occurs in our plant, and the large seeds (of which there are only three or four in each carpel) are also fur- nished with a conspicuous wing on the lower side ; but the radicle js certainly superior. It is yet uncertain whether the New Mexican plant ever bears leaves. Dr. Bigelow saw it early in the spring, when other shrubby plants of the region were begin- ning to assume their foliage, but it was entirely naked. We must wait for other ob ti this strange shrub, and especially for its flowers, before assigning it a place in the system. As, however, there can be but little doubt of its constituting an unde- scribed genus, we may bestow upon it the provisional name of (unotia holacantha BOTANY.

This variety has leaves sometimes as broad ai those of S. latifolia. Atthe base of the limb of the petals there is remote linear lobe or tooth. In the specimens from Mormon island the middle lobes of the petals are somewhat toothed on the margin, especially near the summit. Lychnis pulchra, Cham. & Schlecht., which was founded on a Mexican plant, seems clearly to be Silene laciiata, Cav. We are not sure that it grows in California, unless, which is possible, S.

Dr. Bigelow’s specimens are rather smaller than Nuttall’s from Oregon, and the leaves are narrower. They accord pretty well with Mehringia umbrosa from Songaria, in our herbarium, except that the leaves are narrower.

Petals about one-fourth longer than the sepals. Stamens 10. Styles rarely 4. Ovary and young fruit globose-ovate. This species resembles S. pubera, but that has less pubescence on the stem in two lines; the leaves are much larger, narrow at the base, and nearly smooth, except on the margin, and the sepals are broader as well as more obtuse. The present plant has much the aspect of a Cerastium, but the styles are almost invariably only three, and never five. CERASTIUM OBLONGIFOLIUM, Torr. in Sill.

Flowers about half as large as in the eastern plant. (They are quite as large in specimens of C. lanceolata, Hook., collected in the Rocky mountains by Burke). Calyx one-third the length of the petals. Corolla apparently pale rose-color. This is the only peren- nial (corm-bearing) Claytonia that we have received from California. Pursh’s C. lanceolata (as intimated in the Flora of North America), is a spurious species, made up of C. Caroliniana and C, alsinoides. The leaves, in all the species of this genus that we have examined, are furnished with a fine intra-marginal vein, in which all the veinlets terminate. CLAYTONIA ALSINoIDES, Sims, Bot.

In water; Duffield’s ranch, Sierra Nevada, May 11; San Francisco, April 8; Corte Madera, April 20, On the western side of America, the range of this plant extends from Sitcha to Quito, but on the eastern side it has not been found south of Newfoundland. Chamisso (in Linnea 6, p. 565) considers the Quito plant as a distinct species, which he calls M. lamprosperma, and states that it occurs also in the island of Unalaschka, and at the Bay of Eschscholtz. In plate 7, figs. 1-2, of the volume quoted, he has given figures of the seeds of that species, and of M. fontana, Our Californian plant has exactly the seeds of M. fontana, and Mr. Nittall’s Oregon specimens have the same; but M. fontana f. from Sitcha, is M. lamprosperma of Chamisso. We find the seeds to vary in size and color, and Dr. J. D. Hooker, in Fl. Antarct., p. 13, has shown that the two species are almost certainly not distinct.

They were bearing ripe fruit on the 16th of March, which must: have Been formed the previous season. The capsules are in perfect condition, and show that no part of the calyx is deciduous. The seeds are about as large as in Hibiscus Syriacus, ovate, black, smooth, and somewhat shining. Testa thick and crustaceous. Embryo straight, lying in fleshy and oily albumen; cotyledons ovate, foliaceous, nearly flat, In all of Dr. Bigelow’s specimens of the Frémontia, the leaves were small, few of them being more than an inch in diameter.

Fruit subglobose, about a line and a hal; in diameter. There can be little doubt of the affinities of this interesting plant. Notwith- standing some of its anomalies, it must be referred to the suborder Hydrangee of Saxifragacem. In Eremosyne of Saxifragez proper the cells of the ovary are one ovuled ; also in Aphanopetalum, and in the new genus Spirwanthemum! of the suborder Cunoniaceew. The hairs, especially those of the leaves, exhibit the same muricate-scabrous appearance that occurs in those of Deutzia, Philadelphus, Fendlera, and other genera of Hydrangew. It is somewhat difficult to determine the xstivation of the petals of this genus, as the flower is open while the bud is yet very young ; but in one or two instances they were slightly overlapping. We dedicate this new genus to the accomplished commander of the expedition. UMBELLIFERA. Eryneium pirrusum, Zorr. in Ann. Lyc. New York, 2, p. 207, & in Marcy’s Report, t. 6.

Hill-sides, Duffield’s Ranch, Sierra Nevada; April—May. Tuber half an inch in diameter, fleshy and farinaceous. Stem (fructiferous) 12-14 inches high, moderately branching. The primary - divisions of the leaves are rather ternate than pinnate. The secondary ones are pinnately and deeply cut, with pinnatifid or sometimes finely dissected segments. Umbels compound, or sometimes decompound ; the rays seldom more than two, unequal. Heads nearly half an inch in diameter. Sterile flowers 15-20, on pedicels 3-4 lines long. Fertile flowers 1-5, sessile. Calyx-tube in fruit covered with conical obtuse tubercles, which are not at all hooked at the point. Teeth of the calyx lanceolate. Styles elongated, recurved. This remarkable species was first collected by Colonel Frémont in 1844 on the American river, and afterwards on the upper waters of the Sacramento, but without fruit. The specimens of Dr. Bigelow have the fruit not quite mature, but fully formed, and yet without any appearance of prickles; instead of which there are rather soft tubercles. In all the other North American species of Sanicula the calyx- tube, in its youngest state, shows the uncinate prickles distinctly. Our plant most resembles 8. bipinnata, but is distinguisued by its long-stalked sterile flowers and unarmed fruit. Sanrcuna Msnzresit, Hook. & Arn. Bot. Beech., p. 142 & 347 ; Hook. Fl.

This plant, which Nuttall referred with doubt to Leptoteenia, and thought (as he had “hot seen the fruit) might perhaps be a species of Polytenia, does not accord entirely with either genus. From the former it differs in having emarginate petals with a long inflexed point, and 6 vittz on the commissure, with numerous true vitte on the back, and nearly obsolete ribs ; the involu- cels also are wanting. From the latter it disagrees in the toothless calyx, as well as in wanting the involucels. The fruit is oval or elliptical, about 5 lines long, and the border is rather thin. Many of the flowers are abortive, and in some of the umbels all are so. The primary rays are about 3 inches long. HERACLEUM LANATUM, DC. Prodr. 4. p. 192. Torr. & Gray, Fl. 1, p. 632. H.

Wet ravines, Knight’s ferry, Stanislaus, May 8; in flower and fruit. Stem 3-4 feet high, nearly simple. Leaves (including the petioles) a foot in length; the primary divisions biternately or bipinnately divided; the segments either all (except the elongated terminal one) coarsely 2-3-toothed, or nearly entire and linear; uppermost leaves simply 3-parted with entire divisions. Umbels on very long peduncles, the primary one wholly female, 9-12-rayed. Involucre 9-12-leaved, scarcely one-fifth the length of the rays. Lateral umbels wholly male. Umbellets many- flowered, about an inch long. Involucels of numerous entire lanceolate leaves. Petals white, broadly oval, emarginate, with a small inflexed point. Calyx with 5 distinct acute tecth. Stylopodium broadly conical. Styles half the length of the ovary, recurved. Fruit about five lines long, often a little curved, or gibbous, laterally compressed: mericarps obscurely ribbed, with large single vitte in the intervals and 4 in the commissure. Seed deeply furrowed on the face, but not involute, with an elevated central ridge; carpophore 2-cleft at the summit. We are by no means satisfied with our disposition of this plant. It rather falls into this genus than into any other known to us; yet it differs much in habit and in several characters from Chero- phyllum. | OsmoruIza BRACHYPODA, Torr. in Durand’s Plante Pratt.

The flowering specimehs collected by Dr. Bigelow are only a foot high. Easily distinguished from O. brevistylis and O. longi- stylis by the very short pedicels of the fertile flowers and fruit, the minute stylopodium, and shorter trapezoidal segments of the leaves. In the short styles it is nearest O. brevistylis, but it is quite glabrous, and the fruit is much more hispid on the angles than in that species. OsMORHIZA NUDA (n. sp.): stylis brevissimis; fructibus obtusis; involucris et involucellis nullis; pedicellis fructu longioribus. Shady woods, Napa valley, April 27. Plant about two feet high. Leaves on long petioles, which, as well as the lower part of the stem, are strigosely ' pubescent; segments broadly ovate, often deeply 3-lobed, coarsely dentate-serrate. Peduncles enlongated. Umbel about 4-rayed; umbellets 4-6-flowered. Flowers like those of O. brevis- tylis. Fruit (immature) very hispid, especially towards the base, crowned with a short conical stylopodium. This species is intermediate between Osmorhiza and Glycosma. ° In its bristly fruit it is like the former, and in the short stylopodium and styles, as well as in the entire absence of the involucres, it resembles the latter. The two genera should, perhaps, be united. Cynapium apurotium, Nutt. in Torr. & Gray, Fl. 1, p. 640. Tamul Pass, April 11; in flower. This plant had not been found before in California. Supeenus?

The genus is alto- gether doubtful ; but it may, perhaps, be referred to Deweya until it is better known ; although the fruit is but slightly campylospermous, so that the plant should, perhaps, be referred to the Seselinew. The seeds and the root-stock have a pleasant aromatic odor, much as in Ligus- _ ticum ; from which genus, as well as from Deweya, our plant differs in the single large vittz which fill the narrow intervals between the thick and corky, almost winged, rather obtuse ribs.

On account of the earlier Helogyne of Nuttall, (founded on an obscure Eupatoriaceous plant from Peru, but apparently with good characters,) the late Dr. Walpers has changed the name of Bentham’s genus to Hofmeisteria, in honor of one of the best phytotomists of the age. This genus, strengthened by a third species, is well marked in habit as well as character. All have palmately-lobed or divided leaves on very long petioles. In H. pluriseta the petioles are an inch or an inch and a half long, while the blade is only 4 to 6 lines long.

A dense and fastigiate shrub, apparently em "BOTANY, [99] 48 of two or more feet {n height; the branchlets whitish or yellowish, but with scarcely a percep- tible pubescence. Leaves more hoary, about an inch long, involute-filiform, slender. Heads fasciculate, 9 or 10 lines long, about a line and a half in diameter, therefore more slender than those of L. pulchella; the scales of the involucre almost as strikingly five-ranked as in that species, but thinner, not so sharply carinate, not green on the back, and not so much pointed, the somewhat scarious margins, especially of the outer ones ciliate with arachnoid and appa- rently viscid hairs. Corolla, style, and the slender achenia nearly as in L. pulchella; but the bristles of the pappus rather less copious, evidently finer and softer, and unequal in length, therefore intermediate between that of the latter species and of L. graveolens. This species is a peculiarly interesting discovery, on account of the transition it establishes between 1. pulchella, a strikingly aberrant form, and the rest of the group to which I had referred to that plant, Lryosyris (CHRYSOTHAMNUS) PULCHELLA, Gray, Pl.

Dr. Schultz (Bipont,) informs me, in a letter, that he has indicated this as a new genus, ‘‘ Tetragonospermum pulchellum, C. H.

APHANTOCHETA ExILIs. (Tab. XI.) Hill-sides in the Napa Valley, California; April 25. A delicate, almost capillary little plant, becoming glabrous; the stems or raniios naked above for an inch or so, and terminated by a head of 3 lines in length, below rather leafy, the leaves half an inch or more in length. Scales of the involucre greenish, except the margins, shining, nearly equaling the flowers. Corolla of the ray reduced to a tube, sheathing the sky and about half its length, the apex somewhat obliquely truncate, with no vestige of a ligule. Disk- corollas with rather slender tubes ; the throat dilated, the border equally 5-toothed. Appendages 3 of the style twice the length of the stigmatic portion. Mature achenia not seen. The five rudi- mentary setulz of the pappus do not exceed the hairs of the achenium in length. This curious little Composita exhibits that modification of the Asteroid style which is seen in Pentacheta, Bradburia, Xanthisma, &c. From the technical characters, the genus would fall into De Can- dolles div. Solenogynee. But the genus to which I imagine it is most related has true rays, namely, the California genus Pentacheta, Nuét.; from which it differs mainly in the fewer- flowered heads, the entire suppression of the Hienla. the longer proper tube of the corolla in the disk, and the reduction of the five bristles «f the pappus to minute rudiments. The latter character furnishes the generic name. Pericome caupata, Gray, Pl. Wright. 2, p. 81. On rocky hills at San Domingo, New Mexico ; October. ‘Als gathered by Dr. Henry on the Mimbres.

Sand bluffs, near Inscription Rock, on the Puerco of the West, New Mexico. A remarkable species, of which only fruiting specimens were gathered. The stems are over a foot long, and do not show the base; possibly they are only branches, but they are perfectly simple. These, like the leaves, (which are 4 to 6 inches long, and 3 to 7 lines wide,) are very rough with short and close papillose bristles, much as in Helianthus Maximiliani. The short and sparing veins are confluent into a false nerve within the margin on each side, making the leaf appear three-nerved. Head short-peduncled, an inch in diameter. Rays not seen. Disk- corollas slender, glabrous. Achenia about 4 lines long, the angles very acute. This species completes the parallel between Wyethia and Balsamorhiza, having the involucre imbricated as in Balsamorhiza Hookeri, &c., while several species of the latter genus are now known with the entirely foliaceous involucres of Wyethia helenioides, augustifolia, &c.

I possess only a leaf of Nuttall’s B. macrophylla, y - BOTANY, [103] 47 and that shows no hoary pubescence; but a specimen from Frémont’s collection (which is re- markable for the foliaceous scales of the involucre being as long as the rays, even two inches in length) connects Nuttall’s plant with our own. The Slieged is more like that of B. Hookeri, (to which B. hirsuta must belong,) but the involucre is very different. - BALSAMORHIZA DELTOIDEA, Nutt. 1. ¢.; var. GLABRESCENS. - glabrescens, Benth: Pl.

'lhis was also collected by Frémont in his second journey, and is mentioned in the account of some new Composite of that collection (in Bost. Jour. Nat.

Napa valley, Califor- nia, on hill-sides; April. The western species of this genus were founded on very incomplete materials, and greatly need revision. But this appears to be different from any before known, on account of the perfectly glabrous, awnless, neither ciliate nor lacerate achenia, with the pappus reduced to a tuft of very minute sete or squamelle at the summit of each smooth and entire wing; and the scales of the involucre are uniformly attenuate-subulate, not at all folia- ceous. The naked peduncles are from 5 to 15 inches long, Leaves slightly scabrous, most of them opposite, 3 to 7 inches long, half an inch or an inch wide, or some of the larger occasion- ally rhomboid-dilated upwards, and these 2 inches wide; the cauline all on petioles of one or two inches in length. _ Encenra Catrornica, Nutt. 1. ¢.; Torr. & Gray, Fl. 2, p. 317.

The accessions which may be expected are not unlikely to efface the distinctions between several admitted genera, mostly founded on single plants, resembling Coreopsis or Bidens except in hay- ing fertile rays. The present plant, which we possess only in an early flowering state, approaches the incompletely-known Narvalina, Cass. (a West Indian opposite-leaved shrub) in floral characters, but it could hardly be joined to that genus with our present knowledge. It is to Leptosyne much what Agarista is to some sections of Coreopsis ; but it is distinguished by the short tube of the disk-corolla, marked at the summit by a beardless ring, as well as by the pappus ; yet, from the eibdaeous case of Coreopsis, one should not be surprised if future dis- coveries were to connect them HETEROSPERMUM TAGETINUM, ny, Pl.

[105] 49 which in the outermost flowers are often oblong, obtuse, and barely half the length of the corolla, but in the others lanceolate, mostly acutish, and almost as leng as the corolla, Al- though the heads are larger than in Douglas’ plant, described by De Candolle, and notwith- standing differences in the characters, yet I think that both these specimens and what I called Cheenactis filifolia, in P? Fendl. p. 98, belong to C. glabriuscula, DO. For, although De Can- dolle in the generic character assigns 5 or 6 pale to the pappus, I find only four in Hooker’s, and his own specimens of ©. glabriuscula, and these are in many flowers almost as long as the corolla, although in others (probably from the exterior part of the head) they are only half that length, as De Candolle described them. In this and the allied genera, little reliance is to be placed upon the particular size and shape of these pales. HYMENOPAPPUS FLAVESCENS, Gray, Pl. Fendl., p. 97, & Pl. Wright. 2, p. 94.

This adds another to the already numerous species of this genus, which so closely resemble one another that they can scarcely, if at all, be distinguished, except by the pappus, or sometimes by the chaff of the receptacle. The present species falls naturally into the section Callichroa, and is only to be distinguished from the more slender forms of L. platyglossa, perhaps, by the rather smaller heads and less hairy achenia, but prin- cipally and surely by its pappus of only five longer and smooth awns.

This is undoubtedly Hooker and Arnott’s species, — on which the genus was originally founded. But there is seldom any chaff on the receptacle within the exterior disk flowers, so that it wholly falls into the section Madaroglossa.

The genus is distinguished from Hemizonia by the obcompressed fertile achenia, completely enclosed by the subtending involucral scale, and by the cuneiform, deeply trifid rays.

I have, however, a specimen taken from a plant raised in the Cambridge Botanic Garden, in 1850, from seeds received the previous year from the London Horticultural Society, under the name of ‘‘ Madaria corymbosa.’ Indeed, it is distinguishable from Madaria by the shape of the fertile achenia alone.

This is well distinguished by the pappus, &c., from any one yet described, and is most nearly related to an unpublished species (C. phityearphi) found by Dr. Parry at San Luis Rey, of which better materials are wanted, but which appears to be clearly distinguished by the larger palex of the pappus, tipped with very short arwns.

Head: in fruit an inch and a half long, broader and proportionally shorter than in M. retrorsus, the external calycnlate scales more foliaceous and spreading. Achenia smooth and glabrous, oblong, acutely ribbed and angled, barely 24 lines long, abruptly tapering into a filiform beak of three-fourths of an inch in length; the pappus only 43 lines long. This may be a larger state of M. laciniatus, (of which I have only a miserable flowering specimen,) but it plainly passes into M, grandiflorus. The achenia differ from those of M. retrorsus, and the lobes or lacinize of the leaves are either spreading or * ascending. . MacroruyNeuvs numius, Benth. Pl. Hartw. No. 1816, p. 320. Hills, near Punta de los Reyes, California; April. The leaves are larger and more glabrate than in my specimen of Hartweg’s plant ; the scape 6 to 10 inches high. The fusiform achenia are from 1} to 2 lines long ; the external rather longer than the inner ones; the latter more strongly and sharply ribbed, as Mr. Bentham remarks, The beak, though apparently full grown, is not longer than the achenium. If it varies so as to be “‘ more than twice the length of the achenium,’’ as Bentham characterizes the species, then it must pass, I should think, into M. Lessingii, Hook. & Arn.; of which we have no fruiting or certain materials; but it is said to have the beak ‘* nearly thrice the length of the achenium.’’ 7 MAcRORHYNCHUS HeETEROPHYLLUs, Nutt. in Trans.

This abounds in California and Oregon, where it is the only annual species known. Hooker pronounces this to the M. Chilensis; and it doubtless must be so considered, if that is held to include all the Chilian species. But the short wing-ribbed achenium (1} to 2 lines long) and long beak (of 3 to 4} lines) distinguish it from M. levigatus, and less decidedly from M. pterocarpus, to one or the other of which Lessing’s M. Chilensis is referred, though in neither are the achenia “ plano-obcompressed.’’ The ribs or wings of M. heterophyllus vary considerably in strength; they are scarcely, if at all, serruelate. When less salient and acute, they remain straight and even; when more developed, especially in the ex- terior achenia, these wings become strongly undulate at or before maturity, sometimes very strikingly so, giving the body of the achenium a remarkable corrugated appearance. Some different state of the marginal achenia has probably served as the basis of Nuttall’s Crypto- pleura Californica ; but I have seen nothing that accords with his character of it, TROXIMON PARVIFLORUM, Nutt. in Trans Amer. Phil. Soc. l. c., p. 434. Macrorhynchus cyn- thioides, Hook, Pl. Geyer, in Lond. Jour. Bot. 4, p. 256, ex char. Sandia mountains, New — Mexico; October. The specimens, with mature fruit, are taller than Nuttall’s; the scapes 9 inches high ; the scales of the involucre tinged with purple, and the ligules of a remaining flower appear to have been purple. I suspect that T. roseum, Nuét., is only a variety of this with pinnatifid leaves and purplish or rose-colored flowers. I should confidently refer the present specimens to Macrorhynchus purpureus, Gray, Pl. Fendl., were it not for the short and stouter beak, of less than half the length of the body of the achenium; and the pappus is, perhaps, a little stiffer.

A widely diffused species, extending nearly the whole length of the continent on the western side, and with us exhibiting some remarkable varieties ; for to this species we must refer not only the Chilian P.

Xorullensis, H.B.K.?, P. aristata, Miche., P. squarrosa, Nutt., and P. filiformis, Decaisne. This species is diwcio-dimorphous, some indi- viduals having small anthers on short filaments, and mostly included in the throat of the corolla, while others bear large anthers on long exserted filaments as in the genus generally. Both sorts perfect fruit, but the former (as is usual in such cases) is the most fruitful. Prantaaco BreeLovi (sp. nov.): pusilla, parce minutim hirsuta vel glabrata, anvua ; foliis carnulosis lineari-filiformibus obtusis integerrimis ; spica brevi-oblongo 3-12-flora densa ; sta- minibus 2; capsula oblongo-ovoidea 3-4-sperma bractea ovata acuta calyceque longiore. Benicia, California; April 23. Leaves 1-2 inches long, half a line wide. Scape 2-3 inches high. Bracts carinate, the margins broadly scarious. Sepals broadly oval, very obtuse, scarious, with a green and thickened centre. Flowers twice as large as those of P. pusilla, in the specimens all perfect and fertile; the two stamens more or less exserted, but not so long as the style. Lobes of the corolla ovate, open or spreading in fruit. Capsule a line and a half long at maturity, when it becomes one-third longer than the calyx. Ovules 2 in each cell. Seeds oblong, nearly as in P. pusilla. By the latter we mean, of course, Nuttall’s P. pusilla, not what Decaisne has taken for it, and characterized in DeCandolle’s Prodromus. His plant, as also his P. perpusilla, is P. heterophylla, Nutt. in Zrans, Amer, Phil. Soc. Nn. 8€7. 5, p. 17%, which, although often larger and with sparingly-toothed or incised leaves, is to be distinguished with certainty only by its 10-28-seeded capsule, more oblong or conoidal in form, and exserted to twice the length of the calyx when mature. P. pusilla has only a pair of ovules and seeds in each cell. These three species accord in being diandrous, (a fact first noted for P. pusilla by Dr. Torrey in his Flora of New York, where, however, the capsule is inadvertently said to be two-seeded, instead of four-seeded ;) but P. tenuiflora, A7é., is not so: they are also sub- dicecious or dicecio-dimorphous, more decidedly so than P. Patagonica, and with the corolla inclined to be closed in the more fertile form, but less so than in P. Virginica* and its allies. *It is remarkable that the diccio-dimorphous character of the wide-spread and variable P. Virginica (which includes P. mingiana ? and purpurascens, (Nutt., of Decaisne) and some allied species, has not long before this been distinctly made out. Both subseres have been described, indeed ; some authors indicating the one, some the é . : b seed described, although specimens of all of them have been examined y cence it Hidily happens that a dried specimen of a truly fertile plant fails to offer some fall-grown fruit and seed.

The range of this species includes all temperate North America, from Newfoundland and Canada, south to Florida and Texas, and west to the Pacific. Had Wallroth’s name of Anoplon been generally adopted by succeeding botanists, it might have been unwise to disturb it, But very small anthers—whether sterile or precocious is uncertain, probably the latter, as the ovary is uniformly fruitful ;—and the corolla, as is well known, becomes connivent-closed after anthesis, its broad lobes involutely and imbricately enwrapping each other, so as to form a kind of beak surmounting the fruit. This is the type of Decaisne’s section Cleiosantha.—Gray, Mss. BOTANY. [119] 63. since Endlicher’s name of Anoplanthus has been adopted by Reuter, the monographer of the order in De Candolle’s Prodromus, while Nuttall has preferred the prior claim of his unobjec- tionable name Gymnocaulis, there can be no question of the propriety of restoring the far older name of Aphyllon, under which Mitchell characterized the genus more than a hundred years ago. There is considerable reason for thinking, however, that the genus will be reduced to a mere section of Phelipza. SCROPHULARIACE. (By A. Gray.) Lrvarta Canaprnsis, Dum.

On Williams’ Fork of the Colorado, New Mexico. The specimens were collected in February, and are without flowers, but they bear the remains of the fruit of the preceding season. The plant is a remarkable one, and may possibly not belong to this genus. The leaves are only one or two lines long, of a thick and firm texture, and arise three or seven together from short spurs or undeveloped branches. The peduncles are opposite and alternate, somewhat spreading, and about as long as the fructiferous calyx. There is nothing peculiar about the capsule ; and the aspect of the plant is that of the section Erianthera. Pentstemon Lewisut, Benth. 1. c.? Rocky ravines, Cajon Pass, California; March 16. The specimen belongs to a shrubb species, and bears only the vestiges of the last year’s fruit. The leaves are not so finely and evenly denticulate as those of P. Lewisii; but for the present it may be referred to that species. PeEnTsTEMON BREVIFLORUS, Lind. Bot. Reg. t. 1946. Knight’s Ferry, on the Stanislaus; May.

San Francisco Mountain, New Mexico, December 16. Imperfect specimens, with fruit only. But they clearly belong to a species which we first received from Mr. William A. Wallace, from Cocomungo and Los Angeles, California ; and soon after from Mr. George Thurber, who gathered it in the same district. Mr. A. B. Gray likewise gathered fragments of the same on the Gila river. It must be one of the showiest species known, and it will appropriately bear the name imposed upon it by Mr. Thurber. The crowded pianicle of purplish blue flowers is often two feet in length, and free from leaves, the lowest bracts not exceeding the peduncles, while the upper are reduced to small and inconspicuous perfoliate disks. Peduncles and spreading pedicels each half an inch to an inch long. Sepals 3 lines long, obtuse or apiculate. Corolla an inch or more in length ; the proper tube about twice the length of the calyx, then abruptly expanded into a campanulate throat, glabrous inside ; the two lips of equal length, and the lobes very similar. Leaves- ap- parently somewhat glaucous, 3 or 4 inches long; only the radical petioled; all the upper cauline connate into a disk, which is an inch or two in width where it is perforated by the stem.

Gravelly hills, Sonora, and Moke- lumne Hill, California ; May. The former specimens, like those of Douglas, etc., are very dwarf and simple; the stem, ot only 2 or 3 internodes above the cotyledons, barely half an inch long, while the flower it is terminated with is fully an inch long. Those from the latter locality, like Hartweg’s No. 1894, are developed into many-flowered branches 4 inches high, the lower part fructiferous. To Bentham’s description of the capsule, from Hartweg’s specimens, we have only to add that it is often nearly linear, 4 or 5 lines long, not much compressed, of a crusta- ceous texture, but at length dehiscent ; the valves bearing the many-seeded placentz. The ovoid seeds are apiculate at each end. The calyx, as in the next species, is very oblique at the orifice; in this it is narrow and prismatic, and its teeth are very short and obtuse. The marked difference between this species and E. Frémonti, and perhaps E. Tolmei, (which we have not seen,) led us to propose its generic separation, as Mr. Bentham has stated ; but his judgment in the combination is fully sustained by the characters of the following intarmiaiiels species. Eunanus Covurert, (Benth. Pl. Hartw. p. 320): foliis inferioribus ovatis oblongisve, supe- rioribus spathulato-lanceolatis pollicaribus; calycis infundibuliformis dentibus lanceolatis, BOTANY.

Coulteri, Harv. & Gray, in the herbarium of Trinity College, Dublin, (Coll. Coult., No. 614 ;) but as no character of that has been published, and as recent specimens lead us to sin it not different from E. Fremonti, the name should be retained for the present species, to which Bentham applied it, although we are not sure that it occurs in Coulter’s collection.

Ovary 2-celled, except near the summit, with no dorsal introflexion of the walls, the placentz not bilammelar. Style nearly as long as the stamens. Notwithstanding the ovary, which is strictly 2-celled, except at the top, we suspect this curious plant to belong to the Big- noniaceee—Sesamez ; but the fruit alone can determine the question. If the seeds prove to be albuminous, we know not where in the order Scrophulariaceze to place it. In one of our few specimens a singular abnormal body was found growing from the outside of the corolla at its base, resembling a long-clawed petal, with a small, truncate, saccate, and involute limb. It is evidently a monstrosity. VERBENACEZ. Verbena prostrata, £2. Br. in Hort. Kew. (ed. 2) 4, p. 41; Schauer in DC. Prodr. M1, 2 547. Banks of the Mokelumne River, California, May 17.

It was found also by Mr. Gibbes in Calaveras county; by Dr. Still- man on the Upper Sacramento; by Mr. Thurber and Rev. Mr. Fitch in the lower part of the Sacramento valley. It is variable in its pubescence, being sometimes almost glabrous. The calyx, however, is always villous. The leaves frequently oblong and narrowed at the base. Besides the principal tuber, from which the stem arries, there are often others at the extremity of the fibrous roots, or rather subterranean branches. They are about three-fourths of an inch in length, oblong, pubescent, tapering to the extremity, jointed, and of a fleshy consistence. Sometimes they show a tendency to ramify. They appear to be true tubers, like those of the otato. r ANTIRRHINOIDES, Benth. in Bot. Reg. fol. 1493, & in DC. Prodr. 12 p. 428. Var. foliis dentatis, interdum sessilibus.

Dry arroyos, on the Great Colorado of California. Our speci- mens are imperfect, having been gathered late in the, season, when the leaves had fallen. The plant evidently belongs to the section Otaria of Decaisne, but we can refer it with certainty to none of the species described in the Prodromus. It is tall, (apparently 3-4 feet high,) some- what branched above, with a minutely pubescent stem. The umbels are numerous, in a termi- nal panicle or raceme, 15—20-flowered. The flowers are apparently white, about as large as in A. variegata. The petals are reflexed, and the oblong entire cuculli are only about one-third longer than the sessile gynostegium. Horn subulate-falciform, slightly exserted. The pol is about 5.inches in length, even, oblong, tapering to a long point. It seems to be nearly allied to A. subulata of Decaisne, but that is pa to have the cuculli twice as long as the gynostegium, and until the leaves are kuowht we cannot be sure that it is a new species.

TELOXYS CORNUTA (a. sp.): foliis repando-dentatis pinnatifidisque calycis laciniis acutis dorso brevi-rostellatis, semine compresso margine obtusissimo. Rocky places, Hurrah creek, New Mexico. Near San Francisco mountain, Western New Mexico, Dr. Woodhouse, (omitted by accident in the botany of Sitgreaves’ report); Wright’s Ooll., No. 1735. Gregg collected the plant near Saltillo, Mexico, (No, 390.) T. aristate differs in the entire leaves, inappendiculate glabrous calyx with obtuse segments, and acutely margined lenticular seeds. T. cornuta is commonly about a foot or 15 inches high, and is often very much branched.. The leaves are deeply pinnatifid, with 2-3 distant lobes on each side. The calyx i is beset with minute elevated glands, and on the upper part of the back of each segment is a short acute spine or tooth, so that in fruit the calyx appears somewhat stellate. The seed is exactly orbicular, thick, rounded on the margin, and closely covered with the utricle, which strongly adheres to its surface. In T. aristata the utricle separates spontaneously from the seed. The genus Teloxys was established by Moquin on Chenopodium aristatum, ne has hitherto consisted of that species only. Jinneus, in the second edition of the Species Plantarum, referred. to C. aristatum, the Chenopodium Virginicum of his first edition, regarding it as a variety only. Dr, Gray, who saw the original specimens in the Linnean herbarium, informs me that the plant i is nothing more than Sueda maritima; and yet it is difficult to understand hew the description of Chenopodium Virginicum, in the Species Plantarum, (ed. 1,) could have been drawn from that plant. The first part of the character (‘‘foliis linearibus obtusis canalicu- latis’’) agrees sufficiently well, but the latter portion (‘‘ peduncularibus axillaribus dichotomis’’) is quite inapplicable. We greatly doubt whether a Teloxys has ever been found’in any of the older United States. Moquin (in DC. Prodr.) states that he has seen Mexican specimens of T. aristata in the Vienna herbarium, but it is more than probable that the plant which he refers to is our T. cornuta. Without the leaves, (which fall away late in the season,) the two species are not distinguishable except by the use of a lens. LOLOMA PLATYPHYLLUM, Mog. Chenop. p. 18, & DC. Prodr. 13, pars 2. p, 60.

On rocks, base of San Francisco Mountain, New Mexico. This species is common at the Copper Mines, New Mexico, and is the same as No. 634 of Mr. Wright’s collection of. 1849, and No. 1789 of the collection made in 1851-52. It is nearly allied to G. laurifolia, Benth. Pl. Hartw. No. 81 and 384; but that has rather obtuse and larger leaves, which are of a - thinner texture and without the iiiskenad muriculate margin. Endlicher (Gen. Suppl. I, No. 1900) has proposed to separate G. Fadyenii, Hook. Ic. t. 333, a native of Jamaica, as a genus, under the name of Fadyenia, on account of the sepals didnt at the tip in the male flower, the absence of a free portion of the (perianth i in the female, and the short thick recurved styles. In — - his Suppl. IV, No. 1899, he ha as added four other species from Mexico to this genus. In G. elliptica, however, (the original species,) the sepals cohere at the tip as much as they do in G. Fadyenii, nor have we detected i in the pistillate flower of the former, the two teeth or free’ portion of the calyx described by Lindley ; ; and the styles are more or less recurved in all the species. The genus Fadyenia is, therefore, without a distinctive character. G. Wrightii is easily dis- tinguished by the roughish, HE muriculate margin of the leaves. It is a shrub about three feet high. The leaves are 14-2 inches long, and from three-fourths to nearly an inch wide, with a strongly mucronate tip. Colonel Frémont found on the — Sacramento, ‘above the Great Cafion,’”’ in 1846, a Garrya nearly allied to this species. It may be thus characterized : Garrya Fremont: foliis lato-ellipticis “utrinque acutis vix mucronatis planis glabris supra nitidis margine integerrimis ; racemis (¢) ramosis; bracteis ovatis acuminatis supra medium connatis, inferioribus 3-floris ; floribus pedicellatis. A shrub about four feet high. Only the male plant was found. The leaves are broader than in G. Wrightii, and are only slightly hairy in the youngest state. The spikes are 2-4 inches long, and seem to be pendulous. The bracts, by their union, form bidentate cups, which, on the lower part of the spike, and frequently throughout, are 6-flowered, (three flowers on each side.) This seems to be the normal inflor- escence of the genus, for in G. elliptica, and often in G. Wrighstt, besides the primary flower in each bract, there are two small rudimentary ones. _. Another apparently undescribed species of this genus is No. 633 of Wright’s Western Texas ~ and New Mexican Collection, (1849.) It is also in the earlier collection of Lindheimer. We have only the male plant. The leaves (including the petioles) are 24-3 inches in length, oblong and obovate, obtuse, slightly mucronate, nearly glabrous and somewhat shining above, pub- escent underneath, smooth and ‘even on the margin; spikes shorter than the leaves, bracts lanceolate or ovate, flowers on ‘Short pedicels. Lindheimer and Wright seem to be the only botanists who have collected it. ‘ we propose for it the name of G. Lindheimeri.

It was found also by Dr. Parry” botanist of the Mexican Boundary Survey, while under command of Major Emory. We have also received specimens of it from Mr. Burke, and the acorns from Dr. Andrews, It is a near ally of Q. densiflora, Hook. & Arn., which is also a native of California, but is easily distin- guished from that species by the remarkable scales of the cup.. The leaves are exceedingly variable, for although they are usually more or less lanceolate-oblong, sometimes they are obovate. They are commonly obtuse, but occasionally quite acute, even on the same tree. In the specimens collected by Dr. Bigelow and by Mr. Burke, the leaves are 4—5 inches long, and entire, except a few of them which are obscurely repand-dentate. The male aments are in clusters, about 4 inches long and about 3 lines in diameter; at their base are a few female flowers. The acorns are 2 or 3 together; the cup is an inch i in diameter and thickly covered with rigid subulate or filiform scales, which are at length reflexed or recurved. 7 The acorns are short and thick, about three-fourths of an inch long, obtuse, with a short abrupt point, and of a light- -brown color.

It presents some diversity.in the size and lobes of the leaf; but the acorns vary more than in the eastern oak. They are generally larger, and the glands are sometimes more than two-thirds immersed in the cup, with the upper scales elongated ; but more commonly the cup is much more shallow and the scales more nearly uniform in size. The largest acorns are an inch and a quarter long. Quercus Garryana, Hook. Fl. Bor.—Amer. 2, p. 159; Hook. & Arn. Bot. Beech. p. 391; Nutt. Sylv. 1, p. 1, t. cs Santa Rosa Creek, California.

We know not what else to do with this well characterized willow but to describe it as a new species. It does not appear to have been noticed by any writer on the plants of California and Oregon. The species to which it seems nearest allied is S. planifolia of Hooker. The male flowers were not found. In the collection of Dr. Bigelow was a Salix with female catkins only, which is perhaps the same species as the one just described, but in a younger state. The leaves are silky-pubescent under- neath, and slightly pointed. ; : ” Two or three other Salices were collected in California, but we are unwilling to decide on them without a more extensive study of all the allied species than we can give them at present.
