barbigera, and the P. elliptica. All these form a marked group which ean be 
expressed by the name Pelea sp. c. apocarpa. 
Drake Del Castillo, in his ‘‘Illustrationes Florae Insularum Maris Pacifici,”’ 
united the genera Melicope and Pelea with Evodia. The latter genus differs, 
however, from Pelea in the strictly tetramerous flowers, while the genus Pelea 
has never less than eight stamens. Melicope again differs from Pelea in the im- 
bricate petals. The writer has here adhered to the original classification, uphold- 
ing the genus Pelea, as has also been done by Engler in his treatise on the family 
Rutaceae.
