This is a perennial, native of Campeachy ; and flowers in May. 
A Plant of molt extreme Angularity, refembling nothing in the whole 
Vegetable world, except two other Species of the fame Genus ; and of 
qualities as peculiar as its form. The Leaves are three or four inches 
long, and rife feparately from the ground, with long flender Footftalks. 
They are of a fine bright green ; but the colour foon fades, and they 
become brown, and droop. The Stalk, which fupports the Head, 
rifes naked and Ample from the Root, and is flender, and ten inches 
high. At its top ftands a flat Head of Flowers, half buried in a fpungy 
receptacle of a fquare form, which fills the bofom of the Cup, and 
grows into one body with it. The colour of the Receptacle is pale ; 
and the Flowers are of a whitifh green. They are fm all, one leaf’d, 
and enclofed in a little Cup, which grows to them, as the Cup does to 
the Receptacle; fo that they are very difficultly feparated or examined; 
Hence has arifen the difficulty of giving a true character of the Plant, 
by thofe, whofe fyftems made it neceflary to introduce every part. 
2. PINNATIFID FEVERWORT. 
Plate 7. Fig. 2. 
Chara&er of the Species. Dorftenia Drakena.

Segments, with entire Edges \ the Head is oval. 
Fig. 2. a b. 
This alfo is a perennial, native of Vera Cruz, and other parts of the 
Spanifh Weft-Indies ; a Plant not at all lefs Angular than the preceding ; 
and flowers in June. The Leaves are of a deep ffrong green ; they 
rife fingly from the ground, with long Footftalks, to the height of 
about eight inches. The Stalk which fupports the Head, is about 
feven inches high, naked and flender. The Head is green, and the 
Flowers are of a greenifti white.
