Near Jabucoa, Sinte?its {i^s)> t^^ type locality. 



The description given above is drawn from a portion of the 

 type specimen kindly communicated by Stephani. Although this 

 specimen show^s that the species Is probably distinct, it does not 

 bring out clearly the range of variation, and it may be necessary 

 to modify the description in certain details when the plant becomes 

 better know^n. For this reason it has seemed inadvisable to figure 

 the species at the present time. 



C. Sintenisii is somewhat smaller than the preceding species 

 and is more densely pinnate. In its autoicous inflorescence it 

 agrees with C. variabilis but differs from all the other species 

 known from the island. It may also be distinguished by the ab- 

 sence of teeth on the leaves and bracts and by the shorter horns 

 of the perianth.'
