NEW SPECIES, MAINLY CALIFORNIAN. 31 
segments of a half-inch in length : raceme loose, 5—10-flower- 
ed; petals 23 lines long, the limb obovate, truncate ór retuse, 
lilac, marked with pinnate veins of deeper color: pod slender, 
ascending, an inch long, less than a half-line wide, not beak- 
ed, cells 12—15-seeded 
Description from cultivated specimens: seed collected in 
1886, on Santa Cruz Island, where the plant may be common, 
and is to be sought in shady places on the northward slope: 
allied to C. oligosperma of the mainland, but very distinct ; 
the flowers quite as showy as in some perennial species of the 
genus. 
THYSANOCARPUS CONCHULIFERUS, Greene, Bull. Torr. Club. 
xiii. 218. Glabrous and glaucous, 3— 10 inches high, rather 
stout and branching: uppermost leaves remotely toothed, 
the middle and lower as remotely linear-lobed (the lobes 
straight and divaricate), all except the lowest auriculate- 
clasping : racemes short and dense: petals spatulate-oblong, 
nearly a line and a half long, light purple: samara a line and 
a half long, cymbiform, the somewhat conduplicate margin 
parted into spatulate lobes, or these coherent above, leaving 
narrowly oblong perforations : style a half-line long beyond 
the margin of the fruit: pedicels a half-inch long, firm but 
recurved. 
This most interesting insular species was described, in the 
plaee referred to, from some fruits gathered out of the rock 
crevices where the plant grows, supplemented by the dead 
and almost leafless stems. A cultivated specimen enables me 
to amend and finish the description, The flowers are very 
large for the genus. 
RIBES MARSHALLII. Glabrous, the branches armed with 
stout, but rather short, triple spines : leaves roundish, 5-lobed, 
the lobes incised: peduncles 1-flowered: flower pendulous, 
an inch long ; calyx-segments elongated-oblong, spreading oz 
recurved, dark purple; petals 2—3 lines long, spatulate- 
oblong, salmon-color: filaments slender, more than 4-inch
