215. Tha.spium trachypleurc.yi, n. sp.,* in fruit, the same M 159 of Parry in 

 T>S1, of which the fruit was too young. It proves to be quite different from 

 that of 77 montanum, var. tcnuifolinm. The genus is uncertain; but it can 

 hardly be well separated from Thaspium. 217. T. moxtantm, Gray, Pi.

 either of NuttalFs species under those names, on account of the very long and 

 subulate leaflet of the involucel as well as calyx-teeth, yet apparently rela- 

 ted to them; the foliage, &c, very similar. Mature fruit not collected ; some 

 of the present collection pretty well formed has the win is abortive, while in 

 younger fruits of 1861 these are obvious and somewhat undulate. This dubi- 

 ous plant inhabits "dry hills in the middle mountains, and is a very aroma- 

 tic herb." The foliage of the dried specimens and the fruit have a pleasant 

 anisate flavor,— characters unknown in the polymorphous genus CymopterMs, 

 and rendering the genus of this plant yet more doubtful.

 specimens of the ordinary form of this species ; and in the alpine region also 

 a depauperate form of it, some specimens of which, having a pair of leaves 

 lower down on the stem, and those from the upper axils small, might readilv 

 be mistaken for C. Suecica. They are distributed as Xo.-437 of Parry.
