Together with Thrinax Wcjidlandiana and Biiridd Bnceras, this 

 species forms, in large part, the sparse and low forest growth (cliapar- 

 ral) near Hato, in the interior part of the pcninsida which runs out from 

 the island to the southwest and is comprised in the (enn "s(nilh 

 coast." In this particular locality the original forest had probably 

 been removed and the chaparral can perhai^s be regarded as an inter- 

 mediate stage in the plant successions which woidd eventually result 

 in the establishment of a denser forest of taller hardwood species. 



The specimens from the Isle of Pines, almost without except ion, 

 have fewer pinna; (usually four pairs) and fewer leaflets to a pinna 

 (usually less tiian twenty i)airs) than are stated for the species in the 

 older descriptions.
