sepals. Each of these consists of a one-celled ovary, tapering into a 

 style, which is grooved along the whole of its internal angle, and 

 ends in a slight stigmatiferous swelling. In the ventral angle of each 

 ovary is a vertical placenta, bearing on each of its two lips a row 

 of horizontal nearly anatropous ovules, early flattened against one 

 another. In the fruit, which consists of five pods,' spreading into 

 a star, these ovules have become imbricated, ascending, compressed 

 seeds, each surmounted by a long broad wing, and containing a 

 fleshy embryo with convolute cotyledons. This genus consists of 

 South American trees ; three species are known, from Brazil, Peru, 

 and Chili." Their leaves are persistent, simple, and alternate, with 

 two little lateral caducous stipules. The flowers are in axillary or 

 terminal, usually few-flowered, biparous cymes. The central flower 

 is nearly always hermaphrodite.

 and an androceum of more than ten stamens. The flowers are uni- 

 sexual, oftentimes dioecious. In the male flower (fig. 448), the recep- 

 tacalar cup bears on its edges five quinc uncial sepals, five alternate 

 petals, and a score of stamens, five superposed to the sepals, and the

 pod or legume would appear the preferable ex-

 clefts, one ventral, the other dorsal.
