OF ARTS AND SCIENCES: NOVEMBER 11, 1863." 185 



1st. In a dry ravine of Shasta Mountain, at the elevation of 8000 

 feet : a dwarf state, in flower only, a span high ; the foliage resembling 

 that of T/daspi perfolialum. 2d. On the Diablo Mountains, five degrees 

 farther south, on the top of a dry mountain, alt. 3200 feet ; in flower 

 and fruit, 9 inches high. Flowers rather smaller, more numerous. 

 Lower cauline leaves 2 inches long, very glaucous. 3d. On San Carlos, 

 of the Mount Diablo range : in flower and fruit, with more naked and 

 virgate branches, one or two feet high ; the calyx hoary or downy, 

 but otherwise the plant is quite glabrous and glaucous, as in the other 

 forms. 



-t- -1— Wholly glabrous and somewhat glaucous : cauline leaves not 

 cordate nor auriculate at the base, entire or very obscurely 

 toothed. Flowers violet-purple. 



8. S. hyacinthoides, Hook. Bot. Mag. t. 3516 ; Gray, Gen. 111. 2, t. 

 61. S. glahrifolius, Buckley in Proceed. Acad. Philad. Flowers in 

 the virgate raceme spreading and soon pendulous, green and violet- 

 purple ; the calyx cylindraceous. Siliques erect-spreading (2 - 4 

 inches long, a line wide). Seeds with a narrow wing. Leaves linear- 

 lanceolate and oblong-linear. — E. Texas and the adjacent part of 

 •Arkansas. 



-1— -f— -i— More or less furnished with bristly simple hairs : cauline 

 leaves or some of them usually auriculate- or sagittate-clasping 

 and laciniate-toothed. Flowers, at least the calyx, crimson-purple 

 or red. 



9. S. GLANDULOSUS, Hook. Ic. t. 40. Cauline leaves narrowly 

 lanceolate and mostly sagittate-clasping, their sparse teeth with cal- 

 lous rather than glandular tips. The lax raceme with the pedicels and 

 flowers glabrous or nearly so ; calyx ovate. Siliques narrowly linear 

 (2 or 3 inches long, less than a line wide), straight or curved, ascend- 

 ing. Immature seeds slightly wing-margined. The cauline leaves are 

 commonly sagittate and the siliques glabrous. But Dr. Brewer has 

 collected a form with the leaves slightly auricled at the base, and the 

 siliques beset with a few bristles. — California. 



10. S. HETEBOPHYLLUS, Nutt. in Torr. & Gray, 1. c. Cauline 

 leaves oblong and lanceolate and sagittate-clasping, mostly hispid. 

 Pedicels in the lax raceme spreading in flower, deflexed in fruit, com- 

 monly (as well as the calyx) more or less hispid. Siliques deflexed, 

 straight, very narrowly linear, teretish-subtetragonal, 3 or 4 inches long,
