ongh it IS not unlikely that further specimens may show that it is a variety only. 

 ■Mueller describes the ovary as 1 -celled. In the Howers examined, I have always found a 

 i-^sepmient between the 2 ovules in this as in all other species of the genus. 



4. P. distigma, Benth. Stems erect, lioary-tomentose, with the stature 

 3iia general aspect of some specimens of P. longifoUa. Leaves linear, entire, 

 narrowed into a short petiole, glabrous or nearly so. Peduncles slender, 

 shorter than the leaves, mostly 2-flowered. Sepals ovate-lanceolate, acumi-

 prostrate or creeping. Leaves on slender petioles, the lower ones ovate, 

 OMiise or emarginate, deeply cordate, under 1 in. long, the upper ones
