cence. The gynzceum consists of a shortly stipitate ovary, sur- 
mounted by a curved style with a truncate stigmatiferous apex. The 
solitary suspended anatropous ovule has its micropyle superior and 
exterior. On the placentary edge of the ovary is a little longitudinal 
expansion, which becomes a thin rigid wing in the dry flattened 
indehiscent samaroid one-seeded fruit. The descending compressed 
seed contains a fleshy embryo, with a straight superior radicle. P. 
nitens,' the only known species of this genus, is an unarmed tree 
from Brazil and the countries to the south of it. It has alternate 
paripinnate leaves with little caducous stipules, and its flowers form 
little catkin-like axillary racemes, with scaly bracts. 
Sindora has hermaphrodite flowers, which are at first imbricated, 
but which fall early. The short convex receptacle supports a calyx 
of four sepals,’ of which the posterior really represents two, imbricated 
only by their bevelled edges, as in Detarium and in most of the 
Copaivas. The corolla is represented by a single elongated petal 
superposed to the posterior sepal. There are ten hypogynous 
stamens, of which the posterior is free and sterile, its ill-developed 
anther containing no pollen. The nine others are monadelphous 
and declinate at the base at first, then free, bearing anthers, of which 
the seven anterior‘ are sterile, and the two alternipetalous fertile 
and well-developed. These two anthers are introrse, two-celled, and 
dehisce by two longitudinal clefts. The gynzceum consists of a 
shortly stipitate ovary, containing from two to four or five obliquely 
descending or transverse ovules, and surmounted by a style, which 
is at first rolled up, and which ends in a slight stigmatiferous dilata- 
tion. The fruit is a shortly stipitate irregular orbicular flattened 
coriaceous bivalve pod, covered with prickles, and containing an 
ovoidal exalbuminous seed, whose funicle is dilated into a cupuli- 
form aril. The embryo is thick, with fleshy cotyledons and a short 
included radicle. Sindora consists of unarmed trees from tropical 
Asia and Malaysia, whose leaves are alternate paripinnate and pauci- 
jugate, and whose flowers form terminal ramified racemes.
