The branches are slender, with internodes 1-2 inches long; 
the leaves are 2^-4^ inches long, lj-l| inch broad, on a petiole 
8-10 lines long: the rachis of the axillary panicle is 5^ inches 
long, with about eight alternate primary branches 2 inches long, 
diminishing upwards, the (three to seven) alternate secondary 
branches, about 3-6 lines long, bearing on their apex from one 
to three sessile flowers, about ^ line in diam. in bud. The drupes 
are said to be reddish and shining, about 5 lines in diameter. 
59. Aristega. 
This genus is proposed for a plant in the Hookerian herbarium, 
obtained from the Collection of the East-India Company, and 
registered as from the Helford herbarium : no locality is stated ; 
but it may be presumed to be of Indian origin. It has ovate 
leaves, rounded at the base, acuminate at the summit, 3-nerved 
as well as triplinerved, the nerves extending beyond the middle 
and archingly anastomosing with the few other lateral nerves ; 
the petiole is short and slender. The inflorescence consists of 
two or more raceme-like panicles which spring out of the knotty 
axils of the leafless old branches ; in these the rachis is slender, 
longer than the leaves, furnished sparsely with short branches 
again branched, the branchlets supporting from one to three 
pedicellated flowers, all bracteolated at the articulations and 
rigidly pubescent ; the flowers have nine sepals in three series, 
alternately smaller, the outer bracteiform, the intermediate 
somewhat larger, the three inner ones double the length of the 
former, nearly orbicular, very concave, thick, with their margins 
valvate in aestivation ; they have three petals, smaller than the 
sepals, fleshy, cuneately oblong, subconcave, emarginated at the
