 n, 1917- 



Description. Leaflets sessile, elliptical in outline, nearly 

 equilateral, with a broadly rounded apex and a similarly 

 rounded, sometimes obliquely, inequilateral base. Margins 

 entire. Texture coriaceous. Length ranging from 10 to 

 13 mm. Maximum width, midway between the apex and 

 the base, 4 to 5 mm. Midrib stout, prominent below, 

 channeled above, relatively straight. Secondaries promi- 

 nent, numerous, subparallel, camptodrome. 



This species is well marked and readily distinguished 

 from other members of the flora. It is comparable with 

 the existing Drepanocarpus lunatus Meyer, a widespread 

 form ranging from the West Indies and southern Mexico 

 to Brazil, and recorded also from tropical West Africa. 

 Species referred to Drepanocarpus have been described 

 from the Eocene of Monte Bolca, Italy and from the upper 

 Oligocene or lower Miocene of southeastern France. The 

 existing species comprise 8 to 10 trees or high climbing 

 shrubs, all of which are confined to tropical America with 

 the single exception noted above.
