 Dracocephalum raoldavica L. Sp. PI. ii. 595 (1753). Flowers white. Colima, 



January 9 to February 6, 1891. No. 1225. 



This is a medical plant much useil by the ^fexicans and sold in the market at 



Colima. It is ])robably <'ultivalcd in the gardens, but it was not seen by Dr. 



Palmer in any of his (!xcur>i()iis. 



The specimen from soutliern Mexico, doubtfully referred by Mr. llemsley to 



I), parriflornm, could hardly be confused with this species.

Mr. Watson says of it in a letter dated Oet<djer 23, 1891. "That must be A'to- 

 n'la acuh'dia. We have seen tiie siune thing essentially from the West Indies 

 and Brazil, and the A'ariety liirsiitissimn is described as having the cymes corym- 

 bose-capitate."

I have not seen specimens of C. (/lobofoii^. My specimens differ from the descrip- 

 tion of that species in having only 3 stamens and mueli larger leaves. 



* Pisonia aculvatn L« Guaymas, Ajiril 1 and 2, 1891. No. 175a. Specimens of 

 this plant are again collecte<l by Dr. Palmer. The following note was sent me by 

 the late Dr. Watsiui: 



"Cryptocarpus (?) capiiatiiH Watson [Proc. Amer. Acad. xxiv. 71 (1889)]. Fresh 

 bpiMumens of this doubtfully named species, collected by Dr. Palnujr at (Juaymas, 

 show it to be a form of the widely-distributed and very variable Fixonia aculeata. 

 It does not differ essentially from the var. Mr.Hiilisiiima Schmidt. Fl. Bras. xiv. 3,54 

 distinguished by its blunt obovato leaves and dense, short-hirsute pubescence. The 

 want of spines (they are few on these specimens also), the unusual form of the leaves, 

 and the presence of only staminate UoAvers served to etfectually disguise Dr. Pal- 

 mer's original specimens." — S. W.
