BOTANY. 145 
fourths of an inch in diameter, the pedicels 1-2 inches long.  Bracts linear-lanceolate, about . 
half the length of the pedicels. Sepals greenish-white, narrowed into a short somewhat callous 
claw, from which spring 5-7 (rarely more) strong nerves. The gland is obscure, occupying the 
whole breadth of the base of the sepal, toothed on the upper edge, the teeth running into the 
thickened bases of the nerves. Stamens shorter than the sepals. Anthers roundish-kidney- 
form. Capsule about an inch long, almost as broad near the summit as at the base. Seeds 
broad and shining, compressed, variously indented, and angled. We have thrown this and the 
preceding species into the genus Anticlea of Kunth , As they are excluded from Amianthium by 
having a gland on the sepals. The character of Anticlea being drawn from A. Sibirica and A. 
glauca will require to be slightly modified to receive the species we here refer to it. Zigadenus 
will retain Z. glaberrimus and other species with a creeping rhizoma. Z. elegans of Pursh is 
` pretty certainly Anticlea glauca.

ScoLroPUus BraELovir. (Tab. XXII.) Tamul Pass, Marin county, not far from San Francisco, 
on the opposite side of the bay ; past flowering nnt i in April. We have specimens in full 
flower, collected by Mr. Samuels, but in what part of California we have not been informed. 
The leaves are 6-8 inches long and 2-4 inches broad, varying from acute to rather obtuse. 
They are marked with from 5 to 7 primary nerves, which are narrowly winged on the under 
surface, and above they are sprinkled with minute purple dots. The pedicels are from ۲ to 12 
or more in number, 3-8 inches long, about the size of a packthread, and more or less tortuous. 
Dr. Bigelow informs us that they spread out and lie upon the ground after flowering. The 
exterior leaflets of the perianth (or rather sepals) are about 7 lines long, apparently of a dull 
purplish-color, and widely spreading. The inner leaflets, or petals, are scarcely half a line 
wide, and about the length of the sepals. Stamens one-third the length of the sepals, and in- 
serted at their base: anthers more than a line long, manifestly extrorse. Ovary tapering up- 
ward; style 3-cleft nearly to the base; the segments subulate, recurved. Capsule (immature) 
about two-thirds of an inch long, acute at the base, apparently loculicidal. Ripe seeds not 
known. This remarkable new genus is placed at the end of Melanthaces chiefly on account of 
its extrorse anthers, notwithstanding its one-celled fruit and parietal placentation. "The some- 
what dichlamydeous flowers are suggestive of Trilliacese, but the extrorse anthers, as well as 
other characters, would seem to forbid its being placed in that group. In Melanthaces, however, 
Tofieldia and Pleea have introrse anthers. If it were not for the loculicidal placentation, (so 
rare a character in Endogens,) we might regard Scoliopus as intermediate between Melanthacese 
and ۵۰

Enum. 4, p. 218. Hills near Forest City, California; May 21. All the specimens from this 
locality are one-flowered. The stigma is manifestly 3-cleft, with the segments recurved.
