contiguis, infima pedunculata (rarius remota longissime exserte pedunculata); bracteis culmo brevioribus vel infima paullo longiore; stigmatibus 3; perigyniis ovalibus acute triquetris rostratis nervatis glabris (ore emarginato antice altius secto); squama ovata cuspidata membranacea apice ciliata medio viridi trinervi longioribus; achenio ovato acute triquetro. California, Yosemite Valley, Brewer, 1639, Bolander, 6198, Hillebrand, 2305, 2308, 2314; Mount Dana, 12,000 feet, Bolander, 5086; Soda Springs, 9,000 feet, Brewer, 1778. Whole plant except perigynia and scales whitish or glaucous-pubescent; the sheaths densely so. Culm 1-3 feet high, erect, acutely triangular. Leaves shorter than the culm, 3 - 4 lines wide. This and C. pubescens, Muhl., C. dasycarpa, Muhl., C. tenax, Chapman, C. triquetra, Boott, and C. Halleriana, Asso, form a very natural group, which Carey has indicated in Herb. Gray as Triquetra. Dedicated to the Director of the Survey under which the specimens were collected.

CAREX LUZULINA, Olney, n. sp.: spicis 4-5 rarius 6 fusco-ferrugineis; superioribus contiguis brevi-oblongis densifloris sessilibus, terminali mascula, foemineis inferioribus bracteatis longe vaginatis, infima interdum longe pedunculata remota; stigmatibus 3; perigyniis oblongoovalibus vel ovatis rostratis bifidis obsolete nervatis glabris rostro serrato squama ovata obtusa castanea nervo pallido-viridi ciliata brevioribus; achenio obovato. California, Mendocino City, Bolander, 4740. Culms 7-12 inches high, leafy at base: leaves short, 2-4 inches long, 3 lines wide, smooth and flat; the lower recurved. Allied to C. præcox, Jacq.

CAREX GLAUCODEA, Tuckerman, MSS. "Spicis 4-5 cylindricis, terminali mascula subsessili clavata, reliquis fœmineis folioso-bracteatis multifloris, superioribus approximatis exserte (inferiori remota longe) pedunculatis pallide viridibus; stigmatibus 3 brevibus; stylo æquali ; perigyniis ovoideis turgidis obtusis ore sub-integro multinerviis glaucoviridibus squama late ovata breviter cuspidata albida medio viridi trinervi vix dein duplo longioribus; achenio obovato triquetro."- Moist trap rocks, summit of Mount Holyoke and Mount Tom, Tuckerman ; New Jersey, C. F. Austin; woods near Philadelphia, C. E. Smith; Bethlehem, Penn., Prof. Porter; Lancaster Co., Penn., L. Fiot; Delaware, near Wilmington, Canby. - Plant scarcely erect; culms 6-12 inches high, smooth and glaucescent in all parts; leaves wider than in C. grisea, 2-4 lines wide, shorter than the culm. From C. grisea it differs in its wider leaves, cylindrical densely and many-flowered spikes,

in the glumes, fewer-nerved perigynia, smaller ovoid always pointless perigynia. From C. flaccosperma it differs in its smaller ovoid always pointless perigynia. C. flaccosperma and C. grisea agree in their oblong and pointed or almost rostrate fruit. The closest affinity of C. glaucodea is probably with C. granularis.

CAREX SARTWELLIANA, Olney, n. sp.: spica subelongata castanea e spiculis 56 (rarius 4-8) cylindricis densifloris erectis, terminali mascula, reliquis foemineis castaneis sub-squarrosis sessilibus approximatis; bracteis evaginatis, inferioribus culmum superantibus vel infima subinde sterili remota vaginata; stigmatibus 3; perigyniis castaneis triquetris rostratis (ore integro oblique secto) undique pubescentibus squama ciliata et pubescente lanceolata cuspidata vel ovata castanea nervo viridi latioribus et longioribus; achenio perigynio conformi triquetro angulis costatis. - California, Yosemite Valley, alt. 6,000 feet, Brewer, 1,636; Bolander, 6,221. Culms 2-3 feet high, glaucous, and whole plant pubescent, the sheaths of the leaves densely so. Allied to C. scabrata, Schw. and C. amplifolia, Boott; the three species forming a natural group. From the latter it may be distinguished by its shorter fertile spikes and densely tomentose or pubescent perigynia: from the former by the shape of its almost nerveless perigynia. - The C. Sartwellii of Dewey being only C. disticha, the present well-marked species is now dedicated to the memory of the late Dr. Henry P. Sartwell, of Penn Yan, New York, who has done so very much for the Caricology of the United States.

CAREX CINNAMOMEA, Olney, n. sp.: spicis 3-5 erectis, terminali mascula fusiformi cinnamomea longe pedunculata, reliquis fœmineis cylindraceis densifloris, superioribus approximatis, inferioribus longe exserte pedunculatis basi attenuatis laxifloris, infima remota; bracteis vaginatis culmo longioribus vel brevioribus; stigmatibus 3; perigyniis ellipticis triquetris viridibus rostellatis glabris nervatis (ore bidentato intus ciliato) squama ovata vel obtusa membranacea spice ciliata cinnamomea medio viridi latioribus longioribus ; achenio triquetro obovato. -Swamps of Red Mountain, Humboldt Co., California, Bolander, 6477. Culms 14-2 feet long, erect, with short and narrow scabrous leaves, the rudimentary ones dark purple. The species belongs to the Debilis group, agreeing with C. Sullivantii, Boott, in having erect firtile spikes, and with C. glabra, Boott, in its sharply two-toothed, prominently nerved, and smooth perigynia.

PARRYELLA, Torr. & Gray, Nov. Gen. Leguminosearum.

Calyx obconicus, 5-dentatus, dentibus brevibus æqualibus. Petala nulla. Stamina 10: filamenta ima basi calycis inserta, libera: antheræ uniformes. Ovarium biovulatum; stylus crassiusculus e calyce leviter exsertus, apice uncinatus; stigma glandulæforme laterale Eysenhardtiæ. Legumen indehiscens, oblique obovatum, grosse glandulosum, basi attenuata calyce persistente stipatum, semine solitario ovali repletum. Cotyledones oblongæ, foliacea; radicula inflexa. Frutex Novo-Mexicanus, parvus, ramosissimus, fere glaber; ramis tenuibus scopariis foliisque parce glanduloso-punctatis ; foliolis plurijugis cum impari filifor mibus canaliculatis petiolulatis; stipulis stipellisque nullis vel ad glandulas parvas reductis; floribus pusillis in spicis terminalibus.

PARYELLA FILIFOLIA. New Mexico, along the Rio Grande below Albuquerque, Dr. C. C. Parry. Flowers barely a line and a half in length; the turgid Psoralea-like legume 3 or 4 lines long, not wrinkled, smooth, but beset with large yellowish glands in the manner of Dalea, its base only covered with the turbinate persistent calyx. Filaments and pubescent style barely exserted. Although the stamens are distinct to the base, yet this is evidently a true Psoraleaceous plant, and closely related to Eysenhardtia; but not to be confounded either with that genus or Amorpha. The preoccupation of the name Parrya in behalf of the arctic navigator need not frustrate the natural desire that our Dr. Parry's name should be commemorated in a generic type of his own discovery, inhabiting some of the wide western regions which he has so faithfully explored during the past twenty years.

DALEA PARRYI, Torr. & Gray: suffruticosa, tenuiter puberula ; ramis gracilibus diffusis mox glabris; foliolis 7-11-jugis obcordatis vel obovatis emarginatis (14 – 2 lin. longis) parce grossius glandulosopunctatis; spicis longe pedunculatis elongatis multifloris demum laxis; calyce sericeo-canescente ad medium usque 5-fido, lobis 4 oblongis obtusis, infimo lanceolato acuto paullo longiore; corolla saturate violaceo; legumine glabello. D. divaricata var. cinerea, supra, p. 335.

Gravelly hills near Fort Mohave, Dr. J. G. Cooper, and lower down on the Colorado, near the mouth of Williams River, Dr. C. C. Parry. The specimens of the latter are smoother as to the foliage, and therefore agreeing in this respect with Bentham's D. divaricata of Lower California; but the silky-canescent calyx (fully a line and a

half long) and the apparently larger corolla also (fully 4 lines long when well developed, and richly colored) lead to the conclusion that this is a distinct species.

ASTRAGALUS ARIZONICUS: (Micranthi?) procumbens, suffrutescens, pube strigulosa canescens; stipulis parvulis petioli basi adnatis ; foliolis 5-7-jugis linearibus acutis; spicis in pedunculo folium superante sparse plurifloris; floribus subsessilibus; calycis dentibus subulatis tubo campanulato æquilongis; corolla albida sursum purpurea, carina apice inflexo producto obtuso; leguminibus immaturis oblongolinearibus estipitatis cano-puberulis pl. m. obcompressis septo completo bilocellatis pleiospermis. - Arizona, near Camp Grant, April, Dr. Edward Palmer. Probably same as the plant from Tubac, Dr. Parry, and Los Nogales, Capt. E. K. Smith, mentioned at the end of my revision of the genus (p. 234). But Dr. Palmer's specimens are less white, the calyx with some dark hairs intermixed, and the flowers smaller; those in Capt. Smith's specimens are half an inch long, in both too large to be properly ranked among Micranthi. The inflexed and almost beak-like but obtuse summit of the keel is nearly as in A. Sonora and A. humistratus.

ASTRAGALUS (PHACA) PALMERI: cinereo-puberulus, glabratus; caule ultrapedali; stipulis brevissimis; foliolis 8-13-jugis oblongis ; spicis in pedunculo folium superante strictis laxius multifloris; bracteis subulatis pedicello brevissimo æqualibus; calycis dentibus subulatis tubo campanulato fere æquilongis corolla purpureo-cærulea dimidio brevioribus; leguminibus arrectis estipitatis puberulis plano-compreis semi-ovatis, suturis acutis haud introflexis, ventrali medio 5-7-sperma. - Camp Grant, in Southern Arizona, Dr. Edward Palmer, comm. Engelmann. Base of the stem not seen. Leaflets 6-9 lines long. Spike 4-5 inches, flowers 3 lines, legumes half an inch in length. From the fruit it should be placed with the Homalobi, but the habit is rather different, and the pod very broad.

ASTRAGALUS HORNII (PHACA, Inflati): caule erecto (ut videtur bipedali) glabro; stipulis minimis subulatis discretis mox reflexis ; foliolis multijugis oblongo-linearibus adpresse pilosulis; pedunculis folia æquantibus capitato-plurifloris; floribus fere sessilibus; calyce corolla flavida rectiuscula dimidio brevioribus, dentibus subulatis tubum brevi-campanulatum subæquantibus; leguminibus (pro sectione parvulis) arcte capitatis estipitatis brevi-ovatis acuminatis pilosis inflatis 10 15-spermis. Near Fort Tejon, or in Owen's Valley, Tulare Co.,

in S. E. California, Dr. G. H. Horn, 1863. This belongs to the subdivision which comprises A. macrodon (of which the fruit is still unknown) and A. Douglasii. It is remarkable for the capitate flowers, rather few ovules, and very pointed, ovate-acuminate, crowded pods, which are barely two thirds of an inch in length.

LATHYRUS SULPHUREUS, W. II. Brewer (L. ochroleucus? Torr. in Bot. Whippl., p. 21, non Hook.): caulibus acute angulatis; foliolis 8-12 oblongis vel ovato- seu oblongo-lanceolatis subcoriaceis rigidis (lin. 618 longis) reticulatis; stipulis semisaggitatis sensim acuminatis vel acutissimis; pedunculis folium adæquantibus plurifloris; floribus brevibus (semipollicaribus); calycis dentibus valde inæqualibus ; corolla sulphurea obtusissima, vexillo alas carinamque latam semirotundatam tantum æquantibus. — In woods, &c., along the foot-hills of the Sierra Nevada, from several collectors. Variously confused with L. ochroleucus, venosus, &c. Apparently the color of the flowers alone has caused it to be referred to the former, and these are not "yellowish white," but truly "sulphur-yellow." The limb of the keel is almost as wide as long.

CASSIA COVESII: pube brevi sericea subnitente undique incana; caule 1-2-pedali e radice perenni; stipulis setaceis; foliolis 2-3jugis ellipticis basi inæqualibus mucrone cuspidatis, glandula cum stipite tomentoso setacea inter omnia paria; racemis corymbosis plurifloris; legumine pollicari brevi-oblongo fere recto tumido canescente pedicello paullo longiore seminibus horizontalibus fareto, valvis submarginatis. Camp Grant, and south of Prescott, Arizona, Dr. Elliott Coues (to whom the species is dedicated) and Dr. Edward Palmer. "Root used by the Indians as a cathartic. Flowers bright orangeyellow." In aspect, foliage, and flowers very like C. Lindheimeriana, except that there are never more than 3 pairs of leaflets; and the legume is very different, resembling that of C. bauhinioides and C. Ræmeriana, but more turgid; the oval seeds apparently horizontal.

POTENTILLA (COMARUM) DEPAUPERATA, Engelm. MSS.: pilosula, erecta; foliis pinnatisectis; foliolis lineari-lanceolatis, panicula pluriflora; sepalis purpurascentibus e basi lata attenuato-subulatis accessoria angusto-subulata bis excedentibus; petalis parvis linearibus atropurpureis; staminibus 5; carpellis 2 in receptaculo longe villoso. -Williams Mountain, Western New Mexico, A. L. Anderson. "A remarkable species, connecting, as it does, Ivesia with the section Comarum." G. Engelmann.
