rum approximatis ; calycis dentibus triangulari-lanceolatis, tu"bo 

 brevi loiigioribus ; vexillo brevi calycem parum superante ; 

 legumine dispermo. 



A T. amahili, floruiii structura affini, differt imprimis calycis 

 tubo dimidio breyiore et stipulis angustioribus ; habitu omnino 

 diversum, capitulis ad basin ramorum glomeratis, refert potius 



Dalea 0NOBRTCHTS3 DC. Upper valley of tbe Eimac 8000- 

 10,000 feet ! Scarcely distinct as a species from D. Ifutrsii, 

 Kunth . 



Astragalus Pickebingii, A. Gray^ Bot. TJ. S. Eccpl. Exped. 

 p. 415, var. serpens, noh. Above Casapalta ! 



Ehizomate tenui, ramoso, caudiculos humitusos longe serpentes 

 Riepius subterraiieos, stipulis ultra medium coalitis vagiiiantibus 

 instructos, demum sub din foliiferos, edente ; foliis coufertis, 

 cano-Yillosis, 10-15-jugis; foliolis oblongis, obtusis, truncatis; 

 poduncuHs axillaribus, pauciflorisj petiolis vix sequilongis ; calycis 

 tubo lougiusculoj quam dentes subsequales lineares obtusiusculi 

 duplo longiore; petalis ocbroleucis, vexillo calycem vix duplo 

 superante ; legumine — ? 



A small specimen in Kew Herbarium from Wilkes's Exploring 

 Expedition sliows sometliing of tbe same mode of growtb, but 

 mucb less marked than in tbe Casapalta specimens. 



AsTBAGALrs CASAPALTENSis, u. sp. Above Casapalta, about 

 14,800 feet ! 



PygmsBUs, rhizomate lignoyo; ramis plurimis brevissimis pro- 

 stratis, stipulis fere usque apicem coalitis obtectis, deinde foliif oris 

 et florigeris ; foliis novellis sericeis, mox glabrescentibus, 10-14- 

 jugis; foliolis late oblongis ovalibusve, obtusia, ssepius truncatis; 

 floribus axillaribus, solitariis vel geminis, subsessilibus ; calycis 

 pilosi tubo campanulato, dentibus oblongo-lauceolatis, obtusi- 

 usculis, a^quilougis ; vexillo Iseto purpureo calyce bis longiore; 

 ovario piloso, 4-ovuIato. 



A very distinct species, with smaller flowers than any otber of 

 this group that 1 have seen. A. Alpamarcce^A. Gray, Bot. U.S. 

 Expl. Exped., has fewer leaflets, and difters in the structure of 

 the calyx, which has sharp triangular teeth, and in the two- 

 celled ovary, which has only one ovule in each cell- A. uniforus^ 

 DC, which has flowers twice as large, difiers more widely from 

 the Casapalta plant.
