242 ricker: synopsis of albizzia 



BOTANY." — A synopsis of the Chinese and Formosan species 

 of Albizzia. P. L. Ricker, Bureau of Plant Industry. 



In a study of the specimens of Albizzia collected in China by 

 Mr. Frank N. Meyer, agricultural explorer of the U. S. Depart- 

 ment of Agriculture, specimens were found not agreeing with the 

 descriptions of existing species, and, as a further examination 

 of the material in the U. S. National Herbarium and a part of 

 the material in the Arnold Arboretum showed the determinations 

 of many of the specimens to be in a state of confusion, it became 

 necessary to make a critical study of the material in order to 

 determine what names to use. All of the Chinese species thus 

 far reported belong to the subgenus Eualbizzia. 

 Sect. I. Macrophyllae. Leaves 1-4-pinnate, leaflets 3-6- 

 pinnate, mostly broad and large, 2-4.5 cm. broad 

 and 4-9 cm. long, the costa slightly or not all 

 excentric. 



A. Flowers pedicellate.

This species is distinguished from all of the nearest related 

 species by its pedicellate flowers.
