 America, Columbia, Peru, Chili, Venezuela, Guiana, Brazil, the 

 West Indies, and Middle and Southern Africa.* 



Var. pauciciliata, n. var. Scales sparingly ciliate-bristly or nearly 

 naked. 



Cuba, Plantge Cubenses Wrightianae, No. 3418, mixed with S. 

 tenella, Kunth, in Dr. Gray's Herbarium. 



* Pursh records 8. Mriella, Willd., in Flor. Amer. Sept., i, 46, as growing 

 "in dry woods on slate rocks : Virginia, Carolina. The smallest species." 

 Dr. Torrey notes on the margin "Pursh's plant in Herb. Lamb, is Isolepis 

 stenophylla." 



Here may be noted : — 



iS. inierrupia. Richard. Closely resembles 8. hiriella, Swartz, differing in 

 the transversely tuberculate-rugose achenium.

S. hiriella, Swartz, var. y, Boeckeler, Linnaea, xxxviii, 441. 



I have seen no specimens of this plant from North America, though it has 

 been recorded by several authors. It occurs in Cuba (Plantae Cubenses 

 Wrightianae without a number, and mixed with 8. verticillata, Muhl), and 

 was originally described from specimens collected in French Guiana. Boeck- 

 eler (Linnaea, xxxviii, 441), reduces it to a variety of 8. hiriella, Swartz, but 

 I regard it as a distinct species. The achenium is very similar to that of 8. 

 veriicillaia.
