88 1[44] BOTANY. 
Ints Dovenastana, Herb, 1. c. Hill-sides, Grass Valley, California; May 19. The tube of 
the perianth is longer than in our original Douglasian specimens of this plant. 
Var.? Mason: floribus majoribus ; ; pedicellis elongatis (fere unc. longis). Corte Madera, 
California; April 10. 
Iris Musounignst, Nutt. Jour. Acad. Phil. 7, p. 58? Sandia Mountains, New Mexico ; 
October.. In fruit only. Leaves rather rigid, 4-5 lines wide. Scape 1—-2-flowered. enaning 
1-11 inch long, obtusely triangled, abruptly contracted at the base; statutes slightly prominent. 
Seeds obovate, somewhat compressed, reddish brown. Rhizoma ‘hick and creeping, clothed

IRIS MACROSIPHON (sp. nov.): pumila ; suboauleaccns: rhizomate gracili ; foliis angustis erectis; 
caule bifloro; perianthii imberbis tubo prelongo seaeto' petalis apice denticulatis; ovario 
attenuato Siasiies pedunculato. Hill-sides, etc., Corte Madar: California; April 10. Leaves 
less than one-third of an inch wide. Stem (exclusive of. the flower) 2-3 inches high, the bracts 
somewhat unequal. Flowers as large asin I. versicolor, bright purple. Tube of the perianth

MELANTHACER.. ®, 
PRoSARTES Hooxert: foliis sinu profundo cordatis caulem amplectentibus; umbellis ot tlntie: : 
perianthio basi obtuso, phyllis lanceolatis obtusiusculis ; antheris linearibus glabris ; stigmate 
fere integerrimo. Uvularia lanuginosa 8. major, Hook. Fl. Bor.-Am, 2, p. 174. Mountains; 
near Oakland, California; April 4. Very near P. lanuginosa of the Atlantic States, but differs 
in the strongly cordate and clasping leaves, more numerous-flowered umbels, and in the form 
of the sepals. 
PROSARTES TRACHYANDRA (sp. nov.): foliis AN aot basi rotundatis seu vix subcordatis 
arcte sessilibus, inferioribus amplexicaulibus; umbellis 2-3-floris; perianthio basi subacuto, 
phyllis rhomboideo-lanceolatis ; antheris oblongo-linearibus hirtellis; stigmate integerrimo. 
Hill-sides, Duffield’s Ranch, Sierra Nevada ; May 10. This species is eaaily ilieiseiniinbed from 
the preceding by its scarcely cordate leases, broader attenuate sepals, and especially by its 
hispid anthers. The stem is about two feet high, and dichotomously branched. The flowers 
are as large as in Uvularia perfoliata, and of Ss mpepnish white color. At the base of each hope 
is a distinct nectariferous pit. 
VERATRUM VIRIDE, Ait. Kew. ed. 1, 3, p. 422; Torr. Fl. New York, es p. 317. Swamps, near 
the South Yuba, California ; May, (with enatecnded flowers) ; ; and marshes, near San Gabriel, 
(leaves only.) 
AnticLgea Nurratiy, Amianthium Nuttalii, Gray, Melanth. Revis. in Ann, Lye. N, York, 4, 
p. 123. Amiantanthus Nuttallii, Kunth, Enum. 4, p. 181. River banks, Wekelomne Hill, gad 
Sonora, California ; May, (in fritit.) This is the Poison or Death Camass of the Northwest 
iutiana, The root is a bulb the size of a musket ball, and is covered with a blackish skin, 
but is white within. We find the sepals to vary in £50, from very obtuse and emarginate to 
acute or acuminate, The gland is a small, roundish, discolored spot, without a very distinct 
margin. 
Aytictza Fremont: foliis lato-linearibus planis, racemo composito interdum simplici ; sepalis 
ovatis brevi unguiculatis acutiusculis 5—7-nerviis, glandula superne dentata, dentibus cum 
basis nervos incrassatos confluentibus. Mountains near Oakland, April 4, fin flower.) Also 
_ found by Mr. Rich near Monterey ; and by Colonel Frémont at Santa Cruz, (flowering in Feb- 
; Tuary,) and on the Uinta River, Utah; June, (in fruit.) It is No. 2009 of Hartwep’ s Californian 
lection. We have specimens of it sélletadci in California by Mr. Douglas, so that it is prob- 
ably Zygadenus chloranthus, Hook. & Arn. Bot. Beech. (excl. syn.) Bulb tunicated, about as 
large as a pigeon’s egg. The stem is from a few inches to 4 feet high, simple or patiieulataly 
branched above, the branches terminating in simple racemes. Flowers hermaphrodite, three-
