MEMOIRS OP THE NEW YORK BOTANICAL GARDEN 



[VOL. 10 



Vernacular Name. Laurelillo (Wurdaek & Mbnachino). 



Distribution. A tree or shrub, the many-flowered inflorescences of which are 

 ferruginous-tomentellous with dioecious flowers, occurring in French and Dutch 

 Guiana, possibly in Brazil according to Mez, and the Venezuelan material cited 

 below extending the range into the crystalline shield areas of the latter area. 

 SURINAME. Along Line A, Plateau B, Nassau Mountains, Marowijne River, 

 Maguire 40791 (J fl. NY). VENEZUELA. Bolivar: occasional on lateritic clay 

 near radio tower, Iron Mining Co., of Venezuela mine at El Pao, Maguire & 

 Wurdaek 35809 (? fl. NY) ; Delta Amacuro : El Palmar-Raudal Trail, upper Rio 

 Toro Drainage, Serrania Imataca, Wurdaek & Monachino 39662 (fr. NY). 



The taxon here considered agrees in all respects with the fragment of the 

 type of Oreodaphne cayennensis which Mez has assigned to 0. canaliculata, but 

 does not appear to be the same as the specimen in the photograph of "Patris?." 

 If there is a discrepancy the earlier name should, of course, be applied to the 

 material that has been going under the name of 0. canaliculata for the past 

 half -century. Examination of the type (Patris?) is necessary to resolve the 

 nomenclatural problem, and Richard's specimen should retain the epithet 

 "canaliculata."
