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

 throat of the corolla; anthers included, i mm. long, the apex recurved; 

 style about 4 mm. long, widened at the apex; pollen grains about 

 23-25 n in diameter, and about 40 w long; capsule unknown. 



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

 Indios, May 21, 1910, No. 456, 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 Stenandrium droseroides, but they differ 

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

 different color. The two species are quite similar in general ap- 

 pearance.
