 ours annuals. 



P. prostrata, Caa'. Procumbent or prostate : leaves oblanceolate or spatulate-linear (sel-

 involucre-(2 lines long) of narrower bracts: palete of the pappus ovate or ovate-lanceolate, 

 abruptly long-awned, or some nearly awnless. Varies with peduncles not longer than the 

 head. — Less, in Linnasa, vi. 709 (excl. syn.); DC. 1. c. 99 (excl. .syn.) ; Griseb. F. Brit. W.

* * Pappus pauciaristate ; viz. of 1 to 5 or 6 upwardly scabrous (usually slender and setiform 

 but rigid) awns, at most dilated onlv at very base, with or without a short cliaft'y crown of con- 

 nate or separate squamelUe, sometimes reduced to this, the awns being absent : bracts of the 

 short-cylindraceous rather many-tiowered involucre linear, at length with involute margins 

 partlj' surrounding outer akenes: low and much branched annuals, with slender narrow-linear 

 leaves, bearing a few bristles next the base.
