scription in Rel. Haenk. they must be very closely related. They 
are rather less pubescent than the northern forms known to me, and 
the stamens are 3-5, most usually 4. Specimens of D. Fendleri 
from New Mexico, in the herbarium of the California Academy of 
Sciences, have. usually three fertile stamens, with one or two small or 
abortive ones. The number of the stamens has probably very 
slight value in classification. 
DRYMARIA CARINATA. Annual, weak and slender, nearly glabrous, 
1-2 dm. high; leaves ovate or cordate-ovate, apiculate, cuneate at 
base, the broader ones 15-16 mm. long, 17-18 mm. broad; petioles 
nearly as long as the leaves; stipules setaceous: inflorescence loosely 
cymose, dichotomous ; pedicels filiform; sepals 1% mm, long, 
strongly carinate by the deep green midnerve; the margins broad, 
scarious; calyx widely spreading in anthesis; petals oblong % longer 
than the sepals, deeply 2-lobed, the broad margin continued nearly 
to the base: stamens five, all fertile; filaments linear, flattened, nearly 
as long as the sepals: style cleft half-way to the base; seeds light 
brown, minutely roughened. 
A common species of the high mountains of the Cape Region. 
DRYMARIA POLYSTACHYA. Perennial, growing in clumps from a 
woody base, pubescent and somewhat glandular; stems 8-10 cm. 
high, sparingly branched; leaves rather thick, broadly cordate, 
acute, I cm. or less broad, % cm. long, on petioles of nearly the 
same length; stipules small, lacerate; peduncles terminal 1-3-flow- 
_ ered; sepals ovate-lanceolate sub-3-nerved: petals bifid nearly twice 
as long as the sepals, the long claw naked: stamens 3-5 all perfect; 
filaments linear, flattened; Ovary stipitate above the cupulate disk 
into which the stamens are inserted at the summit, the petals at 
the base a considerable distance from them; seeds brown, tessel- 
lated in many longitudinal rows. 
Growing on cliffs near San José del Cabo.
