 414 ; Bridges, 358 ; Poppig, 179. Distinguished from P. Neai by 

 its more glabrous habit, shorter leaves, narrower bracts, smaller

 lata, acuta, ^-f j)oll. longa. Piacemi terminales, denique laxi, 

 elongati ; flores subsessiles ; bracteas ovatae, acutse, lloribus dimidio 

 breviores. Sepala exteriora ovata, acuta, subasqualia ; alaB ovatse,

Province of Santiago, Chile, Phil. ; Cordova, Argentine Republic, 

 in collibus rupestribus, Phil. Grisebach (PL Lorentz., 29) makes 

 this a variety of P. Necei, from which, however, it differs in several 

 other points besides its glabrous habit. It seems to me nearer 

 P. (jnidioides, from which it is distinguishable only with difficulty, 

 chiefly by its (ultimately) very lax racemes.

 8240 ft.. Gay; Volcano of Peteroa, Bridges, 1181 ; Cordilleras de 

 Santiago, Germain. P. fraijilis, Kze. MS., in parte. A good 

 species, its most obvious characteristic being the mucronate wing-
