1917] Blake,— Polymnia Uvedalia and its Varieties 47 
four collections from Florida has much fewer and less conspicuous 
glands, and intermixed with them a considerable number of hispid- 
pilose hairs. Plants collected by T. F. Allen, G. H. Shull, and A. B. 
Seymour at various localities within the range of the typical plant 
somewhat approach the Floridan form in the presence of hispid-pilose 
hairs, but are best referred to the typical form on account of the very 
numerous glands. 
West of the Mississippi, from Louisiana to Oklahoma and Texas, 
occurs a very marked extreme in which the pedicels and to a less 
degree the branches of the inflorescence are so densely and canescently 
hispid-pilose that the glands are practically concealed from view. 
It is interesting to note that one of the specimens of this form, col- 
lected by Lindheimer (no. 381), bears this note on the label in Engel- 
mann’s hand: “Lindheimer thinks it different from P. Uvedalia.” 
On the Bermuda Islands, where it is certainly introduced and seems 
to be rapidly naturalizing itself, this form is the only representative 
of the species. The plant is not noticed in Reade’s list of Bermuda 
plants (1883), and as it is very unlikely that so conspicuous a plant 
could have escaped his notice, it seems very probable that it is a 
recent introduction. 
The three variations of Polymnia Uvedalia may be named and char- 
acterized as follows. 
* Pedicels and branches of inflorescence densely glandular; hispid-pilose 
hairs few or none.
