PLATYSTEMON AND ITS ALLIES. 175 
little more than 4 inch long the stigmas included, obviously 
constricted, the 4 or 5 joints not small, dark brownish or 
blackish, without obvious midrib but marked by turgid and 
and close parallel ridges; stout styles and slender-subulate 
stigmas each about a line long. 
Known only as collected by myself in the hill-country 
east of Livermore, Alameda Co., 3 May, 1895, the exact 
locality near the railway station called Midway. The speci- 
. Mens were nearly past flowering, and well in mature fruit ; 
the joints recalling the nutlets of the common Tropxolum. 
19. P. conrortrus. A foot high, stoutish, short-stemmed, 
very long-peduncled; pubescence of foliage short, sparse, 
not obvious, that of the peduncles as little conspicuous, 
short, scattered, somewhat deflexed: flowers not known: 
carpels 12, large, 14 inches long, dark-colored, glaucous, 
much compressed, the joints few and remote, the whole fruit 
spirally twisted together; the few seminiferous joints rather 
elongated, strongly and turgidly rugose; stigmas subulate, 
flat, ciliolate. 
A large species with remarkable fruit. It is known but. 
in a single imperfect specimen purporting to have been 
obtained somewhere in Lake Co. or Colusa, by Mrs. Curran, 
in 1884, and is preserved in Herb. Calif. Acad. 
20. P. crenatus. Size of the last, equally stout and 
conspicuously long-peduneled; foliage and its hairiness 
similiar, but that of the peduncles spreading, not deflexed : 
flowers unknown: carpels 14, in maturity little less than 1 
inch long including the short linear obtuse stigma, glab- 
Tous, glaucous, constricted but not laterally, the about 8 
joints marked by abrupt deep dorsal sinuses, their sides in- 
distinctly corky-rugose. 
Also known in a single specimen collected at the same 
time and place with the last, and seen in Herb. Calif. Acad.
