Parosela formosa has numerous short, divaricate branches, very 
small, glabrous leaflets, scarious, concave, glabrous, caducous 
bracts, eglandulose, bright rose-purple keel petals and a pale yel- 
low banner. 
PAROSELA JAMESII (Torr.)

Jamesia obovata Rafin. Atl. Journ. 145. 1832. 
Dalea Jamesii Torr. & Gray, Fl. N. Am. 1: 308. 1838. 
Very close to the above species is Parosela triphylla (Pav:) from 
northern and southern Mexico. It has longer and more truly de- 
cumbent or trailing stems and somewhat narrower leaflets which 
are invariably glabrous on the upper surface. P. /Jamesu may be 
only a northern form of the Mexican plant. Here also appears to 
belong Parosela prostrata (Orteg.), of which I have not seen ee 
specimens. 
ParoseLa Wricutn (A. Gray). 
Dalea Wrightt A. Gray, Pl. Wright. 1: 49. 1852. 
Closely resembling P. /amesz, from which it differs in the ap- 
parently more erect habit, the five oblong leaflets and the rose- 
colored flowers. A closely allied species is P. Lutsana (S. Wats.) 
from the north of Mexico (Schaffner, no. 808 ; Parry and Palmer, 
no. 164). It is very low (4-6 cm.), with short decumbent stems, 
slender leaflets and small capitate racemes of yellow flowers. No. 
162, collected by Parry and Palmer;in the same region, appears 
to be a very small form of P. Wright and intermediate between 
it and P. Luisana. Further collections may prove them to be but 
one species,

The type specimen of D. Fremonti, no. 417, collected by Fre- 
mont in the “ Pah-Utah”’ country, southwest California, May 5th, 
1844, is preserved in Herb. Columbia University, and includes 
many specimens since distributed as Dalea Californica S. Wats.
