| À species characterized not only by its small size for those in the 
trifoliolate group, the plant being less than one meter high, but also by 
ïts long-petioled, 3-foliolate, very coarsely undulate-toothed, uniformly 
green, membranaceous, glabrous leaflets, and by its solitary, simple, 
slender, few-flowered, simple racemes that are about as long as the 
petioles, the flowers not at all crowded, mostly 1 to 2 mm. apart and 
solitary, very rarely two together. After Radlkofer’s arrangement of 
the species it belongs in the group with Alophylus serratus Radik., 
46 JOURNAL OF THE ARNOLD ARBORETUM [voL. xIx 
A. fuscus Radilk., À. sootepensis Craib, and À. viridis Radilk., dis- 
tinguished from all by numerous characters, the most evident one being 
perhaps the coarsely repand-toothed leaves.
