320 FLOUA OF SOUTH AMKRICA AND THE PACinC. 



sifolia; 3. Bridgesii, DC. Prodr. v. p. 665. — Valparaiso and 

 Quepay; Bridges, {n. 449.); Cuming, (?«. 724.) — Our plant 

 is certainly the Ilymenatherum Kunthii of Leasing, and we 

 prefer his specific name as he is the first describer of it. It 

 is certainly the Rancagua Bridgesii of Endlicher and Poep- 

 pig, although our plant is not glabrous, and the paleas of the 

 pappus ai-e narrow linear-subulate, and very obscurely and 

 simply serrated. The R. Feuillei, Endl. and Poepp., {Las- 

 thenia ohtusifolia, u. of DC.) has a different structure of 

 the palese of the pappus, which are much shorter than the 

 corolla, though the two plants are in other respects very 

 similar.

Am, in DC. I. c Pectis acicularis, Don, mst. — Mendoza; Dr 



Gillies — Summit of high dry rocks of Los Loamos, N. Pata- 

 gonia ; Tweedie — We almost incline to think that this may be 

 the same as Cassini's /T. tenuifolium, (from " Chili,") and the 

 same as what De Candolle liad from Nee, (probably from 

 Mendoza,) both of which De Candolle is inclined to refer to 

 his H. temdlobum, a Mexican plant. Lessing's genus Hymen- 

 atherum, it will be observed, is very different from this o\ 

 Cassini, and is Cassini's Lasthenia.
