Spermacoce áspera, Vahl, ecl. p. 10. but not of Aublet. Sper- 
macoce læ`vis from Guadaloupe, and Sperm. aspera from His- 
paniola, Spreng. syst. 1. p. 401. ex herb. Balb. Perhaps Sper- 
macoce læ vis, Lam. is identical with this plant, This spe- 
cies, with many others, is very intricate, but is nearly allied 
to B. ramisparsa. It differs from B. áspera, Aublet, in the 
much less scabrous stem, in the shorter leaves, and in the 
smaller whorles of flowers. Flowers white. Bigelonia ás- 
pera, Sieb. is a distinct plant from this. Bristles of the stipulas 
ilose.

guian. 1. p. 60. t. 22. f. 7. Flowers white. Fruit divisible
