A LIST OF PLANTS COLLECTED BY MISS MARY B. CROFT, 1884— 
°85, AT SAN DIEGO, TEXAS, NEAR THE HEADWATERS OF 
THE RIO DULCE, BY N. L. Britton anp H. H. Russy. 
The species here enumerated were collected by Miss Croft 
during the years 1884-1886 and sent to Dr. Rusby for deter- 
mination. His absence in South America has prevented their 
examination until the present time. 
RANUNCULACEA, 
19. Anemone decapetala, L., var. HETEROPHYLLA (Nutt.) 
(A. heterophylla, Nutt., mss.; Wood). We are unable to find 
any characters which would entitle this plant to specific rank. 
Indeed, our specimens show every gradation in _ leaf-form 
from the linear lobes of the typical A. decapetala to the 
nearly entire ones of the variety. A specimen collected by 
Merrill, in Robertson Co., Texas,’ has both forms on the same 
plant. As here recognized, the variety extends east into Ala- 
bama (Buckley) and occurs also in South America, Cuming’s 
specimens from Valparaiso in Herb. Torrey consisting of both 
type and variety.
