324 CALIFORNIA.— SUPPLEMENT. HCruciferm. 
siliculis glaberrimis orbicularibus compressis reticulatis emarginato-bilobis lobis sub- 
divaricatis acutis, stigmate sessili. — Torr. et Gr. FI. l.p. 116. 
A much branched and spreading annual, with long slender racemes of fruit, and recurved compressed 
])edicels. The pouch is very similar in form to that of Lepidium bipinnatifidum, but broader at the base, 
and with the lobes longer and slightly diverging. The leaves and general aspect of the plant are very differ- 
ent in the two. 
4. L. leiocarpum ; glabriusculum, caulibus procumbentibus, foliis pinnatifidis, fructus 
racemis laxis, pedicellis latis planis paten ti-reflexis, siliculis glaberrimis nitidis orbicu- 
laribus compresso-planis marginibus subincurvis apice emarginatis, stigmate sessili. 
Habit of the preceding, but less slender. The leaves are more pinnatifid ; the pedieels broader and flatter ; 
the siliculse rather larger, very glossy, destitute of reticulation ; the margin a little curved upwards ; the apex 
with only a minute notch. 
1. Thysanocarpus elegans {Fisch. et Meg.) ; calyce petalis vix duplo breviori, siliculis 
orbiculari-ovalibus membranaceo-alatis alis foraminibus plurimis pertusis apice emar- 
ginatis, stylo exserto sinus duplo superante. — a. siliculis glabris. — T. elegans. Fisch. et 
Meg. in Ind. Sent.? Hort. Petr op. p. 51. Torr. et Gr. FI. 1. p. 118. — /3. siliculm disco 
tomentoso. 
A most beautiful speeies, very different from the original T. curvipes. Our specimens have all a woolly 
disk to the siliculm, in which particular alone it differs from T. elegans, Fischer et Meyer, and is probably 
the same as the same authors notice from California, as discovered by M. Deppe, differing only in the longer 
style. The present variety is li to 2 feet high, lower leaves slightly pinnatifid and hairy, upper ones glabrous, 
entire, sagittate at the base, racemes of fruit 8-10 inches long. Siliculse of a most elegant structure, margined 
with a broad somewhat crenated wing, in w’hich is a range of rather large oblong perforations all round the 
woolly disk.

— /3. siliculas disco pubescente. 
The var. alone is in this collection, differing in no respect from the original T. curvipes, except in the 
downy fruit. 
3. T. pidchellus. Fisch. et Meg. Ind. Sem. Hort. Petrop. 1835. p. 50. Torr. et Gr. FI. 
1. p. 118. — a. silicula nuda. — /3. siliculee disco tomentoso. 
These two states of the plant are mixed together, as if gathered in the same locality, and I see no reason 
to consider them other than varieties of the same species. The species is chiefly distinguished from T. cur- 
vipes by the much longer style, and the scarcely notched apex of the silicula. 
4. T.pusillus; pubescenti-hirtus ramosus, siliculis orbicularibus vix alatis pilis patentibus 
uncinatis utrinque tectis, floribus apetalis. Hook. Ic. PI. 1. t. 43. Torr. et Gr. FI. 1. 
p. 119. 
A very minute plant. The flowering speeimens probably do not equal an inch in height, but the inflorescence 
runs out into slender racemes, 3 or 4 inches long, bearing silieulae to the very base. Tliese are scarcely so 
large as flax-seed, orbicular, compressed, and not distinctly winged, but clothed all over with spreading uncinate 
white hairs.
