1. P. odoratissima (Jacq. Schoenb. t. 229); “leaves impari-pinnate, 
leaflets about 7 pairs, linear-lanceolate ; pedicels axillary, shorter than 
the leaf.” DC. Prod. 2. p. 216. : 
Has. Raised from Cape seeds, Jacquin. 
Except in the more numerous pairs of lanceolate leaflets and short pedicels this 7 
does not materially differ from P. pinnata, var. e. Having been figured and de- 
scribed by Jacquin from cultivated specimens, it may be only a garden variety. 
2. P. pinnata (Linn. sp. 1074) ; tall, erect, densely much branched, 
pubescent or glabrous ; branches and twigs angular ; leaves impari- | 
pinnate, in 3-5 pair, leaflets linear or lanceolate-linear, acute, very nar- 
Tow ; stipules small, free, lanceolate or ovato-lanceolate ; pedicels axil- 
, long or short, bracteolate beyond the middle, the bracteoles con- 
nate ; calyx very variable in incision and pubescence (see vars.) DC. 
Prod. 2. p. 216. 
Van. a. vulgaris; twigs and leaves villoso-pubescent ; pedicels shorter than the 
leaves calyx glabrescent externally, the ovate-acute lobes ciliate and more or less
