POLYGAL^ AMERIOANyE NOViE VEL PARUM 

 COGNITiE.

(Continued from p. 1-43). 



Sectio D. — Carina eximie cristata. Cauhs suffruticosus, erectus 

 rigidus, vel procumbens carnosus ; folia numerosissima, confertis- 

 sima, imbricata, rigida vel carnosa ; racemi capitati ; se]3ala 

 cxteriora subsequalia ; semina linsuta, strophiolata, biapi)endi- 

 culata. 



This section is divided into two sub-sections. The first, with 

 erect rigid stem, rigid linear leaves, and heath-like habit, includes 

 a few species peculiar to Tropical Brazil. The second section, with 

 procumbent stem, fleshy leaves, and large black seed with two long 

 ai^pendages to the arillode, belongs entirely to extra-tropical South 

 America, with an especially western distribution. The species 

 described in the ' Flora Brasiliensis ' nearly all extend also into 

 Uruguay, the Argentine Republic, and other neighbouring coun- 

 tries. The following species all belong to this latter subsection : — 



12. P. Xecci, DC, Prodr., i., 319 ; Hook. Bot. Misc., iii., 146 ; 

 Gris. PI. Lorentz., 37. Apparently a widely distributed species 

 over western Temperate South America ; distinguished from P. 

 thesioides, Willd., P. aspalatha, Linn., and theii' allies, hj its sessile 

 capsule ; from P. strictu, St. Hil., and other allied species, by its 

 hairy habit, persistent calyx and corolla, and other characters.
