vel retrocurvo eaque duplo longiore. Swamps in the Sierra Nevada, alt. 6-11,000 feet, Brewer, Torrey, Bolander, Bridges (193). A wellmarked and interesting addition to this section. Flowers about half the size of those of P. Grænlandica or surrecta; the linear rostrum barely 3 lines long, thrown abruptly back over the galea and erect or recurved. Capsule ovate, twice the length of the calyx.

PEDICULARIS SEMIBARBATA: Edentulæ, subacaulis, fere glabra; foliis pinnatipartitis, segmentis inciso- 1 - 2-pinnatifidis, lobis dentibusque brevibus mucronatis; floribus breviter pedicellatis folioso-bracteatis in spicam subsessilem foliis multum brevioribus congestis; calyce subinæqualiter 5-fido, lobis e basi lata lanceolato-acuminatis; corolla ochroleuca (primum tomentulosa) calyce triplo longiore, galea fere recta obtusa inappendiculata labio erecto apice breviter æqualiter trilobo paullo longiore; filaments 2 longioribus supra medium pilis multiarticulatis villosis, brevioribus fere vel prorsus imberbibus; antheræ loculis basi breviter cuspidatis. - On Mount Dana, alt. 10,000 feet, and Ebbett's Pass, 7-8,000 feet, Prof. Brewer. In or near the Yosemite Valley, Bolander, and Mariposa Grove, at and above 5,000 feet. Allied rather to P. centranthera, Gray, than to any other; the habit, foliage, and inflorescence similar, but the leaves more divided, only 3 or 4 inches long, and with seldom a trace of callous margins; the flower much smaller, only 7 to 9 lines long; the anthers much shorter and abruptly pointed. Capsule globular, obliquely mucronate, hardly equalling the calyx.

MONARDELLA LEUCOCEPHALA: annua, humilis, cinereo-puberula ; foliis oblongis vel sublanceolatis obtusis integerrimis subpetiolatis; involucri bracteis ex toto albo-scariosis nitidis rotundatis 7-9-nervatis subapiculatis flores (pro genere parvos) adæquantibus; calycis breviuscule tubulosi dentibus subulatis supra medium albis tubo 15-nervi dimidio brevioribus; corolla parva. Plains near Merced, in sandy soil, June. Heads numerous, terminating the spreading branches, about two thirds of an inch in diameter. The slender white tips of the calyxteeth more or less recurved. Corolla apparently white and but little exserted. From the very white and probably enduring involucres of the numerous heads, and the dwarf habit, this marked species may be expected to be a fine ornamental annual in cultivation. The other annual species are M. Douglasii, differing from the others in the widely divergent pinnate veins of the involucral bracts confluent into a strong marginal false vein; M. candicans, with very blunt calyx-teeth as well VOL. VII.

as bracts, and the only species heretofore recognized as an annual; M. undulata, with its larger forms (often confused with the foregoing), the leaves of which are seldom at all undulate, and the bracts are more rigid or foliaceous and less blunt; and the following, which is most like M. Douglasii on one hand and M. undulata on the other.

MONARDELLA BREWERI: annua, humilis, puberula ; foliis oblongis vel spathulatis penninerviis petiolatis; involucri bracteis latissime ovatis subulato-acuminatis plerisque tenuibus 5-7-nervatis vel quintupliseptuplinerviis calyces tubulosos haud superantibus; dentibus calycis obtusiusculis; corolla rosea longius exserta. - Corall Hollow on the dry eastern side of the Californian Coast range south of Monte Diablo, Brewer. Scantily collected, apparently a very distinct species: the specimens little over a span in height. Calyxes merely soft-pubescent; the teeth rather broad, wholly pointless. Nerves of the involucral bracts about 5 from the base, and one or even two pairs from the midnerve near the base, converging to the pointed apex. Corolla 3 or 4 lines longer than the calyx. - The two perennial and more or less suffruticose species are found in California, M. odoratissima only in the mountains, M. villosa in the low country and farther south, and under several forms: among them the var. leptosiphon, Torr., passes into var. glabella (M. Sheltonii, Torr. in Durand, Pl. Pratten. ?) which has smaller leaves and heads, no villosity at all, and scarcely any pubescence.

POGOGYNE (HEDEOMOIDES, stam. fert. 2) SERPYLLOIDES (Hedeoma? serpylloides, Torr. Bot. Whippl.): pusilla; foliis spathulatis vel obovatis; verticillastris paucifloris sæpe distantibus; dentibus calycis bracteisque nudiusculis parce hirsuto-ciliatis, 2 superioribus paullo longioribus corollam adæquantibus; filamentis 2 sterilibus rudimento antheræ capitatis; stylo superne parcissime hispido; stigmatis lobis inæqualibus. Martinez, J. M. Bigelow. Oaklands, Marsh's Ranch near Monte Diablo, Arroyo Grande, San Juan near Monterey, &c., Brewer, Bolander. Plant from 2 to 5 inches high, exhales a strong scent of Pennyroyal. Corolla blue or purple-violet, very small. Flowers in some specimens sparse in the manner of Hedeoma, in many of the older ones numerous and interrupted-spicate as in Pogogyne. Calyx deeply cleft, not bearded in the throat. If it were so, the plant would manifestly belong to Hedeoma. But it is a clear congener and very near relative of Pogoggue zizyphoroides, Benth. (sparingly collected in flower by Mr. Bolander, with larger and roundish leaves),

which equally has two of the stamens sterile, although their filaments are as long as the truly antheriferous ones. I discern a tendency to the abortion of one pair of anthers and to the inequality of the lobes of the stigma in P. parviflora also.

AUDIBERTIA CAPITATA: frutescens, bipedalis; ramis ad apicem usque foliosis glomerulo capitula formi solitario terminatis; foliis A. stachyoidei similibus sed minoribus brevioribus magis petiolatis subtus tantum puberulis, floralibus bracteisque subcoloratis rotundatis vel * ovatis obtusis vel interioribus mucrone setiformi instructis flores adæquantibus et involucrantibus. Summit of Providence Mountain, Mohave Desert, May, 1861, Dr. J. G. Cooper. Flowers purple. Resembles A. stachyoides in the rugose leaves, &c., and A. incana in the involucrate bracts of the head.

SCUTELLARIA BOLANDERI: Galericulata, tenuiter pubescens; caulibus (pedalibus) simplicibus vel inferne ramosis ad summum apicem usque æqualiter crebre foliosis; foliis omnibus conformibus ovatoellipticis basi levissime cordatis sessilibus subintegerrimis (imisve serrato-crenatis) membranaceis penninerviis; floribus axillaribus oppositis folium subæquantibus; pedicellis calyce brevioribus; corolla pallide cærulea seu albida (fere pollicari). Clark's Meadows, Mariposa Co., in patches, Bolander. Leaves an inch or less in length, thin, rounded at summit, in their venation intermediate between S. galericulata and S. nervosa.

STACHYS ALBENS: mollissime albo-tomentosa, nec unquam hirsuta; caule erecto valido (1-5-pedali); foliis cordato-ovatis vel subcordato-oblongis crenatis, inferioribus petiolatis, superioribus plerisque subsessilibus, floralibus calyces adæquantibus; verticillastris plurifloris approximatis sæpius in spicam densam interruptam confertis; bracteis obsoletis; calycibus subsessilibus villosissimis obconico-campanulatis, dentibus deltoideis pungenti-cuspidatis; corolla alba calyce duplo longiori, tubo calycem paullulo superante, galea superne villoso-barbata. -California: Fort Tejon, Mr. Xantus (No. 80, taken for a var. of S. pycnantha): Ojai, Dr. Peckham; Pechecos Pass, near watercourses, Brewer, Bolander; Yosemite Valley, a dwarf exceedingly woolly form, Bolander. Stem in the taller specimens "often an inch square at base, above much branched.” Corolla white, with a few purple or rose-colored dots near the base of the lower lip.

TRICHOSTEMA LAXUM: Orthopodium, tenuiter pilosum vel pubescens; caule laxe ramoso; foliis penninerviis lanceolatis sæpiusve ob

longo-lanceolatis utrinque attenuatis vel acutis longiuscule petiolatis ; cymis axillaribus pedunculatis demum furcatis, ramis elongandis secundo-plurifloris; pedicellis calyce vix brevioribus; lobis calycis æqualibus subovatis tubo æquilongis; corollæ tubo tenut exserto. Near Little Geysers, Napa County, Brewer. Pope's Valley, Bolander. I have also specimens raised from Californian seed, of unknown source, in 1866, by Mr. Elihu Hall. Most related to T. lanceolatum, Benth.; but with much more evolute cymes of smaller flowers; and the distant, petioled, feather-veined leaves are much more like those of T. dichotomum.

LYCIUM COOPERI: ramis validis; foliis viscoso-puberulis spathulatis retusis rigidulis pauci-venosis (cum petiolo 6-9 lin. longis); floribus 5-meris; calyce cylindraceo-campanulato basi abrupto quasi truncato cum pedicello æquilongo viscoso-pubescente, lobis oblongis obtusis tubo suo æquilongis corolla infundibuliformi (semipollicari) dimidio brevioribus; filamentis basi pilosis; antheris ovalibus mucrone minimo apiculatis. East slope of Providence Mountain, in the Mohave District, California, Dr. J. G. Cooper. Stems "2 feet high"; spines very short. Pedicels 3 or 4 lines long. Lobes of the corolla ovate, very much shorter than the tube. The species ranks between L. pallidum and L. puberulum.

LYCIUM ANDERSONII: glaberrimum; foliis parvis (1 – 3 lin. longis) spathulatis; calyce brevi-campanulato margine repando-quadridentato seu denticulato pedicello (sesquilineam longo) sæpius breviore; corolla angusto-tubulosa fere semipollicari fauce subampliata, lobis 4 latissimis tubo multoties brevioribus antheras adæquantibus; filamentis basi glanduloso-pilosis. - S. E. part of State of Nevada, Dr. C. L. Anderson, Allied to the L. Torreyi and L. Fremonti of my revision of the genus.

MENODORA (BOLIVARIA) SPINESCENS: minutissime puberula, ramosissima, ramis ramulisque divaricatis lignosis spinescentibus; foliis nunc ad squamas exiguas reductis nunc parvis (lin. 1 - 3 longis) spathulatis, omnibus alternis; calycis 5- (raro 6-) partiti segmentis linearisubulatis corollæ tubum infundibuliformem (lobis obovatis suis paullo longiorem) subæquantibus; filamentis antheris oblongis subexsertis brevioribus; stigmate minuto emarginato; ovarii loculis biovulatis. Cañons and hillsides, southeastern part of the State of Nevada, fl. March, Dr. C. L. Anderson. This is an interesting addition to the genus, being apparently of the same group with the original South

American species of Bolivaria; but the filaments are short and adnate almost up to the throat of the corolla, The latter is about 3 lines long, and apparently yellowish tinged with pink. Stems one or two feet high.

MONOLEPIS SPATHULATA: foliis integerrimis spathulatis; glomerulis globosis; utriculo pyriformi crebre papuloso-scabro; semine lævissimo turgido immarginato. - Sierra Nevada, at Mono Pass, in loose soil, Bolander. The seed is several times smaller than that of M. chenopodioides.

ERIOGONUM SPERGULINUM: E. pharneceoidei Torr. simillimum; pube foliorum pilosa nunquam tomentosa; inflorescentia floribunda magis effusa; involucris multo minoribus glabris quadrifidis unifloris; perigonii laciniis exterioribus oblongis. Dry sandy soil, banks of Big Creek below the Mariposa Big-tree Grove, Bolander. Also collected by the late Mr. Bridges.

HABENARIA THURBERI: H. dilatatæ et hyperborea peraffinis; spica angustissima; sepalo postico rotundo-ovato; labello angusto lineari e basi haud dilatata deflexo sepalis duplo longiore calcare filiformi ovarium adæquante vel superante paullo breviore; glandulis stigmatis ovalibus. Arizona, Thurber (925), C. Wright (1,900), referred by Dr. Torrey in Bot. Mex. Bound., to Platanthera leucostachys, Lindl., which I take to be a form of P. dilatata. A variety of this with more slender and loose spike of apparently more greenish flowers is 6251 of Bolander's collection, from near the Mariposa Grove and Yosemite Valley.

CYPRIPEDIUM CALIFORNICUM: puberulum; caule folioso (ad sesquipedalem); foliis inferioribus late ovalibus ovatisque, superioribus lanceolatis; floribus 4-6 dissitis folio brevioribus ochroleucis, sepalis (postico e duobus conflato integerrimo rariusve apice bilobo) latissime ovalibus petala lato-linearia obtusa plana labellumque obovato-globosum adæquantibus; stamine sterili fornicato.-Swamps on Red Mountains, Mendocino Co., Bolander. Flowers most like, and rather smaller than, those of C. passerinum.

BRODIEA COCCINEA (Brevoortia Ida-Maia, A. Wood in Proceed. Acad. Philad. June, 1867): scapo elato; umbella 5-12-floro; perigonio infundibulari-cylindraceo ventricoso pedicello tenui duplo longiore coccineo, lobis viridulis mox flavidis ovatis recurvis tubo multo brevioribus squamis faucialibus latissimis erosulis (antheras 3 sessiles subæquantibus) subduplo longioribus; stigmate trifido, lobis emarginatis.
