folia, Sm., but the foliage and — are quite different 
in the two.

bescens, incana, caulibus erectis foliosis, foliis 8—9-jugis, 
foliolis linearibus lineari-cuneatisve, stipulis liberis ovatis 
membranaceis acutis pilosis, racemis pedunculatis foliolon-

parvis), bracteis minutis calycibus rachidibusque nigro- 
adpresse-pilosis, legumine (mediocri) ovato inflato coria- 
ceo-membranaceo reticulato.— Coquimbo, Cuming (N. 
864.)— The habit of this is very similar to that of P. 
aboriginorum, Rich. (Hook. Fl. Bor. Am. v. l. t. 56); 
and the flowers have also a close resemblance, only 
wanting the purple spot on the alae. The fruit, hispees, 
is totally different. -

incana, caulibus czespitosis prostratis brevibus foliosis, 
folis 6-10-jugis, foliolis oblongis retusis, stipulis mem-

cri) ovato inflato coriaceo-membranaceo variegato sub- 
reticulato.—El Cerro de la Polcura, and Las Lefias, on 
the Andes of Mendoza, Dr. Gillies.—Closely allied in 
many respects to the last species, but different in habit, 
hue of the flowers, stipules, and colour of the hairs 
on the calyx. The fruit is almost precisely the same. 
The habitat is widely different. -
