14—23. It is No. 1998 of Hartweg's Californian collection. A showy plant, resembling 
Brodiza grandiflora, but with larger hexandrous flowers, and the ovary elevated on a very long 
stipe.

ODONTOSTOMUM,* Nov. Gen. 
Perianthium hypocraterimorphum, marcescens ; segmentis 6 squalibus patentissimis, 3 ex- 
terioribus 5-nerviis, interioribus 7-nerviis ; tnbo cylindrico segmentis «equilongo, ima basi 
ovario accreto, demum paullo supra basim transversim rupto deciduo. Stamina fertilia 6, con- 
formia: filamenta lato-subulata, plana, discreta, fauci calycis inserta, cum appendicibus seu 
filamentis sterilibus totidem alternantibus: antherae subrotundee, biloculares, fissuris 2 trans- 
versis apice dehiscentes. Ovarium globosum, 3-loculare, loculis biovulatis: stylus gracilis, 
filiformis: stigma minutum. Ovula collateralia, e basi loculi adscendentia, anatropa. Capsula 
globoso-triloba, trilocularis loculicida ; loculis dispermis. Herba Californica, bulbifera? caules- 
cens, glabra; caule e basi parce dichotomo ; foliis radicalibus lato-linearibus, caulinis angus- 
tioribus, summis in bracteas transeuntibus ; floribus albidis racemosis vel paniculatis ; pedicellis 
solitariis 1-2-bracteolatis haud articulatis. 
Opontostomum Hanrwrear. Wet places, Ione Valley, California; May 18. Valley of the 
Sacramento, Dr. Stillman. It is No. 2008 of Hartweg’s Californian collection. Plant about 
two feet high. Radical leaves 3-6 lines wide, flat. Bracts lanceolate-subulate, about as long 
as the filiform pedicels, which are furnished with a subulate bracteole a little below the flower. 
Raceme 3-8 inches long. Flowers half an inch in diameter ; the segments elliptical-oblong, 
rather obtuse, as long as the tube, at length reflexed. Seeds all empty shells in our specimens. 
This genus is allied to Pasithea and Zephyra ; but these differ in the want of sterile filaments و‎ 
the more numerous ovules; in the dehiscence of the anthers, and in several other characters. 
We received it several years ago from our friend Dr. Stillman, of New York, but it seems to 
have been first collected by Mr. Hartweg. 
CLINTONIA ANDREWSIANA (n. sp.): umbellis 2-4 in parte superiori scapi subremotis, terminali 
multiflora, ceteris paucifloris; floribus erectiusculis; perianthiis subcampanulatis; ovarii loculis 
8-10-ovulatis. Hill-sides, Tamul Pass ; also along the Redwood (Sequoia sempervirens) ravines 
of Costa County, east of Pablo Bay, California. The only specimens of this interesting plant 
found by Dr. Bigelow have the flowers scarcely expanded ; but we fortunately, while this report 
was in press, received it in a more advanced state from Dr. Andrews, lately of California, and 
to this gentleman, who has assiduously examined the botany of that State, we dedicate the 
species. No tieket accompanied his specimens, but they were probably collected not far from 
San Francisco. The root consists of numerous thick descending fibres, which proceed from a 
small fleshy tuber. The leaves grow from the summit of a slender, erect, or curved caudex, 
which is 5 or 6 inches long, and clothed below with sheathing scaies. "They are from 7 to 11 
inches long, and 3-4 inches broad, narrowed and sheathing at the base, with a short abrupt 
acumination, glabrous and green on both sides, but the margin sparingly ciliate with slender 
deciduous hairs. The nerves are very numerous, and run from the base to the apex. The 
scape is about twice as long as the leaves, terete, and naked, except a lanceolate or linear 
foliaceous bract at the base of the lower umbel, or at some distance below it. Terminal 
umbel 10-20-flowered ; the lateral ones 2-4-owered and sessile. Pedicels about the length 
of the flower, somewhat elongated in fruit. Sepals 6, about 8 lines long, 5-7-nerved, 
oblong, obtuse, apparently greenish-yellow. Stamens 6; filaments subulate, flat; anthers 
9 From ’odovs, tooth, and cropa, mouth ; in allusion to the tooth-like sterile filaments at the orifice of the flower.
