DOUBTFUL SPECIES. 



Harpalyce Formosa DC. Prodr. 2: 523. 1825. This, the type of the genus, 

 was based upon one of Mocifio arid Sesse's drawings, but the tracing of 

 the drawing seen by the writer is so imperfect that it is impossible to tell 

 what species is represented. It may be the same as H. pringlei Rose.

Leaflets more than 5 ; bracts usually shorter than the peduncles. 

 Young branches pilose with soft spreading hairs. 



Corolla about 2.5 cm. long 2. B. lunata. 



Corolla about 1.5 cm. long 3. B. nudiflora.
