This is a small Indian order limited as yet to a single genus of arborious plants,’ 
‘datingaished by their alternate exstipulate leaves, which are either simple or pinnate, and in 
the latter case are rendered still more remarkable by their being either abruptly or unequally 
innated. The inflorescence is nee the panicles being either terminal or axillary near the 
summits of the branches. owers are small sometimes almost inconspicuous, nearly ses- 
sile, on short lateral beaknslos of a pale greenish yellow and very numerous 
Sepals 5, persistent, unequal, somewhat in a double series : wstiv ation imbricative. Petals 
5, inserted on the margin of the receptacle, deciduous, alternating with the sepals of two kinds ; 
three outer ones orbicular, entire, with an imbricative wativation ; two interior smaller, acutely 
bifid, resembling scales. ‘Stamens 5, opposite to the petals, and slightly united to them at the 
very ‘base; ; three exterior sterile, opposite to the larger petals; two interior fertile, opposite to 
the: bifid petals; filaments of the fertile stamens flat : anther, cells globose, dehiscing eee . 
versely, placed side by side on the inner side of the saucer- shaped connectivum. Disk,

authors. Mr. Arnott and myself aided by a suggestion of Dr. Hooker placed it betweem

order of Sapindacee, while Meisner for reasons which do not appear refers it to Berber siete
