SCHCENOLIRION album, sp. nova. Racemo simplici, circiter 50-floro, 10 polli- 

 cari ; bracteis lineari-lanceolatis, membranaceis ; perigonii patent! foliolis ovalibus, 

 concavis, 3-nerviis, persistentibus, basi breviter connatis, ad apicem glandulis minimis

Of this beautiful plant I had only fragments of the raceme, without scapes or leaves. 



Schtenolirion is a new genus founded by Prof. Torrey on the Phalangium 

 croceum of Mich., Omitlwgalum croceum of Ell., which will soon be published in 

 Whipple's report. " It differs from PJialangium, in the root being bulbous and the 

 cells of the ovary 2 (not several) ovuled, as well as in other characters; from Orni- 

 tlwgalum, in cells not 6 — 8 ovuled, style not capitate 3-lobed ; from Scilla, in the same 

 characters ; from Asplwdelus, in sepals distinct, or nearly so, at base, and 3-nerved, 

 not divided and uninerved, stigma not capitate 3-lobed, nor root fibrous-fasciculate. 

 The genera with which it is most allied "are Camassia and Chlorogalum." Torr. in 

 litt. 



DIOSCOREACE^. 



TRILLIUM sessile, var. giganteum, Hook, and Arm in Bot. Beechey's voy. p. 

 402. The three involucral leaves have a diameter of 8 inches; each leaf is 4x4",

VERATRUM Califor.nicum, sp. nova. Caulis robustus, foliosus, pubescens, foliis 

 ovato-lanceolatis, acuminatis, plicatis, glabris, imis caulinaribus in petiolum attenuatis 

 et cum eo circa pedalibus ; superioribus sessilibus, subvaginantibus. Racemo valde 

 pubescenti, paniculate et circiter pedali ; floribus breve pedicellatis, polygamis ; sepalis 

 ovatis obovatisve, persistentibus, in sicco fuscis et purpureo ad basim maculatis, antheris 

 reniformibus posticis, antice dehiscentibus ; stylis brevibus, recurvis. 



This is undoubtedly different from V. viride of which I have specimens from Oregon, 

 perfectly similar to our eastern plant, except that the leaves are almost round. The 

 color and shape of petals differ entirely ; V. viride has greenish flowers with narrow
