caulis Walsh, M.S., they reside among the brown external pubes- 

 cence." The whole stalks are covered around by a thick brown 

 velvet to the length of one inch. If I did not know the scrupulous 

 accuracy of the Baron in labeling his specimens, I should believe 

 that the specimens in the collection are types of Walsh sent to him, 

 as they are indeed very similar to the preparation used by Walsh. 

 I know nothing similar to this curious gall.
