384 - APPENDIX D. — BOTANY. 



mostly radical and deeply pinnatified; the terminal lobe much 

 larger than the others, and triangular or deltoid. The stem is 

 simple, from one to two feet high, more or less inflated toward the 

 base, and nearly naked above. The flowers are nearly sessile, in 

 a long terminal raceme, erect when first expanded, but finally 

 becoming patulous. Calyx about half an inch long, the sepals 

 oblong-lanceolate and woolly externally. The petals are dark pur- 

 ple, with a pale waved margin. Filaments all free. The siliques 

 are not known.

Except in the greater length of the stipe and the large size of 

 the plant, I see nothing to distinguish Q. aurea of Nuttall from this 

 species.
