130 BANCROFT ON THE HOG-GUM TREE OF JAMAICA. 



there is a small fleshy hypogynous disc, but no calycine 

 glands; and in Pachypodium {Belonites, E. M.,) though de- 

 nied by Endlicher, and omitted by Meyer, there are five 

 large, fleshy, distinct (in P. succulentum) or connate (m P. 

 bispinosmn) liypogynous scales; but none outside the corolla. 



In Christya, owing to the transparency of the parts, the 

 style is very evidently seen to be composed of two styles, one 

 issuing from each ovary, enclosed within a membranous 

 sheath, whose apex expands in a disc-like body, beneath the 

 common pulvinate stigma. This structure is probably that 

 of the styles of other genera, at least of those with double 

 ovaries and simple styles, to many of which, styles expanding 

 at the apex into discs or cvps, are attributed ; and it seems 

 analogous to the structure observed in Goodeniacecc. 



Dr Pappe informs me that Trichocludus verticillatus of 

 Ecklon and Zeyher's catalogue, which they gathered without 

 flower, is our Christya speciosa. I have seen no specimen of 

 their plant, but the ^^ very lovg bipartite capsule" mentioned 

 in their description, whose contents I presume they omitted 

 to examine, may have been the young/o///c/es of our plant.
