 apex. Near the base of the ventral angle of each cell we find two 

 collateral ascending anatropous ovules, whose micropyles look down-

wards and outwards. In the bud they are already flattened and 

 membranous above ; and in the fruit they become winged exalbu- 

 minous seeds, as in QuiUaja. The pericarp is dry ; first it separates 

 into five divisions, each representing a cell, and then each cell opens 

 into two halves from above downwards. As yet only one species of 

 the genus is known, V. corijmbom, a Mexican tree with alternate 

 serrate leaves, whose long petioles have two very small glandular 

 lateral stipules. Its flowers are grouped in very dense terminal 

 ramified cymose panicles, in which the lateral ramifications are 

 axillary either to bracts or to the uppermost leaves of the branch. 



Lindleyci' would have altogether the flower of VauqueJinia but for 

 its imbricated sepals'- and suspended ovules. If we analyse a bud 

 of L. mespiloides^ the only known species of the genus, we find that it
