cence. The gynseceum 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 ilattened 

 indehiscent samaroid one-seeded fruit. The descending compressed 

 seed contains a fleshy embryo, with a straight superior radicle. P. 

 nitens, 1 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. 



Sindorcc has hermaphrodite flowers, which are at first imbricated, 

 but which fall early. The short convex receptacle supports a calyx 

 of four sepals, 3 of which the posterior really represents two, imbricated 

 only by their bevelled edges, as in Betarium 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 4 are sterile, and the two alternipetalous fertile 

 and well-developed. These two anthers are introrse, two-celled, and 

 dehisce by two longitudinal clefts. The gynaeceum 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 exalbuininous 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.
