when dry lilac-colored; filaments about 0.5 mm. long, inserted in the

Type. — Growing in the white sand of the pine-barrens at Los 

 Indios, May 21, 1910, No. 4^6, 0. E. Jennings. Specimen in the 

 Herbarium of the Carnegie Museum. 



The type consists of but two specimens, collected in flower, and, 

 unfortunately, none of the capsules were mature. The plants were 

 growing near the stations for Stenajidrium droseroides, but they differ 

 from that species markedly in the much larger flowers of a totally 

 diff^erent color. The two species are quite similar in general ap- 

 pearance.
