88 CRUCIFERiE. Parrya. 



7. D. macrncarpa CNntt. mfifi.) : " root fibrous and tuberous; radical leaf 

 3-foliolate, the leaflets reniforrn and lobed; cauline leaf solitary, 3-parted, 

 the segments entire, obtuse ; silique very long. 



" Woods of the Oregon, with the preceding. — A small species, remarka- 

 ble for the great length of its silique, its cuspidate and rather long style, and 

 capitate stigma. On the receptacle, (as in the preceding^) there remain some 

 time after inflorescence, 2 filiform denticulations, like abortive stamens. — 

 Described from a single specimen." Nutt. 



8. D. integrifolia (Nutt. mufi.): "rhizoma tuberous; tall and rather ro- 

 bust; radical leaves trifoliolate, leaflets roundish-oval; cauline 3, alternate, 

 3-parted or trifoliolate ; divisions linear-oblong, acute, entire ; siliques rather 

 short, on long pedicels ; petals very large. 



" Plains of Monterey, Upper California. — Stem 12-18 inches high. Pe- 

 tiole of the solitaVy radical leaf very long ; the leaflets large. Flowers 

 among the largest of the genus." Nutt. 



9. D. Californica (Nutt. mss.): "rather robust; leaves trifoliolate, cau- 

 line ones alternate ; leaflets ovate or ovate-lanceolate, crenate or incisely 

 denticulate, acute ; siliques lanceolate-linear, rather long. 



" Monterey, Upper California. — About the size of the preceding species, 

 but with smaUer flowers. Cauline leaves 2-3, nearly as large as the radical 

 ones, and similar in form." Nutt.
