PLATYSTEMON AND ITS ALLIES. 171 
saucer-shaped, deciduous but rather tardily so, the cuneate- 
obovate petals nearly equal, mostly of a deep lemon-yellow, 
only the margins below the middle and the very base 
cream-color: stamens very unequal, filaments of the obcor- 
date outer series shorter than their anthers and of less than 
half the length of the narrow and merely obtuse inner ones: 
carpels about 20 to 24, cohering by their styles, these as 
long as the stigmas, the two of much more than half the 
length of the torulose body, the whole fruit 1 to 1} inches 
long, strongly constricted, the joints about 12, dark-colored 
dorsally, with scarcely a trace of any midnerve, the sides 
glaucous-green, irregularly wrinkled. 
In sandy fields near Tracy, Contra Costa Co., Calif. 25 
April, 1903, Carl. F. Baker; distributed by him under n. 
2780. The species is about the largest one known; the 
petals almost occupied within, as it were, by a large cunei- 
form yellow spot, this leaving only the very base, and the 
lower margins whitish. The tortuous character of stems and 
peduncles is a peculiarity. 
13. P. resseLLatus. Stout and low, 6 inches high or more, 
leafy branches very short: leaves oblong-linear, 1 or 2 
inches long, obtuse, not callous-tipped, hirsute-ciliate : 
peduncles twice to thrice the length of the branches, rather 
few, stout, sparsely yet coarsely and stiffly hirsute: corollas 
cream-color, an inch broad, rotate above a short turbinate 
base, the petals being short-unguiculate: outer filaments 
linear-cuneiform and from strongly retuse to nearly truncate 
at summit, all much broader than the anthers and petaloid : 
fruit ovoid to oblong, 4 to 4 inch long including the short 
coherent styles and linear barbellate stigmas; carpels 12 to 
5, much constricted, pale and glaucous except as to a 
broad low dark-brown dorsal line, usually glabrous, occa- 
sionally with scattered hairs, more rarely quite notably
