LuPiNus MEIONANTHUS : undique sericeo-incanus ; caulibus ut vide- 

 tur herbaceis vel sufFi'uticosis adscendentibus e radice perenni ; foliolis 

 6-9 concoloribus oblanceolatis obtusis ; stipulis parvis setaceis ; brac- 

 teis calyce brevioribus ; floribus minimis (vix lineas 3 longis) verticil- 

 latis in racemum spiciformem congestis ; calyce pedicello longiori 

 ebracteolato, labiis fere integris coroUam glabram subtequantibus ; cari- 

 na apice brevi lato obtuso inflexa ciliata; leguminibus ovatis incanis 

 1 -2-spermis. — Nevada, near Carson City, Dr. C. L. Anderson. It would 

 be unsafe to describe a new Lupine before the old species are settled, 

 except in a case like this, — a silvery-canescent species with remarkably 

 small flowers. These are blue or purple, with a yellow spot on the 

 vexillum. Leaflets 6 to 11 lines long, mostly equalling the petiole. 

 Legumes half an inch long. Seed with a small hilum. 



Trifoliuji Andersonii : (§ Liipinaster) undique albido-villosissi- 

 mum, cjespitoso-depressum ; caudicibus crassis lignescentibus stipulis 

 majusculis scariosis vestitis ; foliolis 4-6 oblongo- seu obovato-cuneatis 

 mucronatis integerrimis ; pedunculis folia adsquantibus ; capitulo glo- 

 ■boso multifloro ; floribus sessilibus ; dentibus calycis tubo campanulato 

 sublongioribus subulato-setaceis ; corolla roseo-purpurea baud scariosa. 

 — Mountains of Nevada, near Carson City, Dr. C. L. Anderson (1862 

 and 1864). A most peculiar species, forming tufts a few inches in 

 height, at first nearly acaulescent, but the stout caudices or stems some- 

 times attaining the length of five or six inches, and ascending or de- 

 cumbent, leafy, beset, as is the whole plant, with very soft silky-villous 

 hairs ; the calyx, &c., very densely so. Petioles and peduncles IJ- to 2 

 inches long. Leaflets half an inch in length. Head very compact, 

 with an alveolate-squarrose receptacle, the outermost very short bracts 

 forming a vestige of an involucre. Flowers half an inch long ; the 

 corolla apparently pink, with paler wings and keel, these adnate by 

 their claws to the tube of filaments. Ovary tomentose, scarcely stipi- 

 tate : ovules about 5. Legume globular, 1 - 2-seeded. 



Trifoliuji bifidum (Gray in Proceed. Acad. Calif, supra cit.) : 

 villosiusculum seu glabellum ; caulibus e radice exili (annua ?) diffusis 

 gracilibus ; stipulis ovato-lanceolatis setaceo-acuminatis integris ; foliolis 

 lineari-cuneatis lateribus rariter dentatis apice bifidis vel excisis mu- 

 crone interjecto ; pedunculis folia bis terve excedentibus; capitulo 

 nudo 6-12-floro; floribus pedicellatis demura reflexis ; calycis 5-partiti 

 dentibus subulato-setaceis parce hirsutis coroUam roseam scarioso-per-
