16. PACHYPODIUM. (Thelypodium, Endl. gen. p. 876.) 



There is an earlier Pacliy podium, by Webb & Berthelot, founded on Sisym. 

 brium Columnae, S. Pannonicum, &c. ; but we suspect it is not sufficiently dis, 

 tinctfroni Sisymbrium.

3. V. grandiflora. — To this species belongs V. brevistyla, no. 7. Our /?. 

 pallida, and the remarks that relate to it, should be excluded : it is a distinct 

 species, which may be called V. jmllida. We were misled by the figure in 

 Brit.jl. gard., which represents the style too long.

30. PLATYSPERMUM, j). 112. 



From Douglas's last Oregon collection, made in the interior, we have beautiful 

 specimens o^ Platyspermum scapigcrum (kindly communicated both by Sir Wm. 

 Hooker and Mr. Bentham), with mature fruit. In this state, the silicle is almost 

 exactly orbicular; the seed with a very broad winged margin, and the cotyledons 

 accumbent ! The genus must therefore be removed to the Tribe Alyssineae.
