On the white quartzose sand, pine-barrens north of Los Indios, 

 May 17, 1910, 0. E. Jennijigs, No. 324 (Type); same date and locality, 

 No. 625. General Distribution: Known only from the type-locality. 



The plants grew scattered about in the pine-barrens, the growth 

 always open and scraggly, the branches few and more or less erect, 

 the leaves small and closely bunched towards the ends of the branches. 

 The flowers occur densely bunched at the apex of the branches, the 

 corolla being light pink and up to 20 mm. broad, glandular-pubescent, 

 as is also practically the whole upper part of the plant. The lance- 

 olate, acute sepals are about 4 mm. long, copiously soft-ciliate with 

 gland-tipped and naked hairs, the peduncles and calyx more or less 

 deeply reddish-purple in color. The filaments are pubescent near 

 the base, this not being a good distinguishing character between 

 K. aggregata and the closely related Kalmiella ericoides of western 

 Cuba (Small, /. c, in the key to species of Kalmiella, noting for K. 

 aggregata: "Filaments glabrous").
