COOK—HABITS OF CACAO AND PATASHTE. 625 
developed into stout woody twigs. Several of the species now 
referred to Theobroma are only imperfectly known. Some of them 
differ widely from the cacao, but apparently without approaching 
nearer to the patashte. It may be that a more definite recognition - 
of the differences between these two will facilitate the study and 
classification of the other members of the group by affording a larger 
series of diagnostic characters. |
