The name of Cratoxyleœ has been given to a small group of plants 

 belonging to this family, characterized chiefly by their pericarp and 

 seeds. The former is capsular, loculicidal, and opens in five pannels, 



Hypericum (Emnanthc) calycinum.

and these sometimes divided into two halves at the partitions which 

 separate. The seeds are ascending and surmounted by a vertical 

 wing; the cotyledons of the contained embryo are generally longer 

 than the radicle. The group consists of tropical trees and shrubs of the 

 old world, with a yellow juice, opposite leaves, covered with glandular 

 punctuations, pentamerous flowers, with triadelphous stamens. Cra- 

 toxylon 4 is Asiatic ; in each ovarian cell are four or more ovules in 

 two vertical series. 5 A dozen species 6 have been described. Ellœa 

 articulata, 7 a shrub of Madagascar, with terminal cymes, has only 



1 The sepals and petals are striated with black. 

 The anthers are primarily introrse.

3 Here is placed, on account of the drupaceous 

 character of its fruit, hut only provisionally re- 

 tained by us, Endodesmia calophylloides, Bentu. 

 [Gen. 166, n. 5 ; Oliv. Fl. Trop. Afr. i. 157), a 

 shrub of the Gaboon with opposite veined leaves 

 like those of Calopkyllum, and quite exceptional 

 in this group by its very numerous stamens, in- 

 separable within from a pentagonal tube (and 

 consequently inonadelphous), and especially by 

 its unilocular ovary which encloses only a single 

 descending seed. The place of this genus is 

 perhaps rather among the Clusiaccœ ; indeed it

much resembles Calopkyllum.

 is also distinguished by a scale at the base of 

 the petals ; a character of very little importance.
