Deppea corni folia. 



is contorted and much resembles that of some species of HypohatJirum, 

 a genus in which the fruit is fleshy. 



Deppea, a small Mexican shrub, has tetramerous flowers, with 

 rotate or short funnel-shaped contorted corolla ; anthers often 

 apiculate, with cells independent 

 below, and a bilocular ovary with 

 ovules inserted on an oblong and 

 peltate placenta ; surmounted by a 

 style often capitate, more rarely 

 bifurcate at the summit. The 

 fruit is a small obovoid or turbinate 

 capsule. The inflorescences are 

 axillary cymes, often few-flowered, 

 loose or umbelliform. 



The true Sipanea has the flowers 

 of Piondeletia, but with contorted 

 corolla. The calycinal divisions 

 are lanceolate and subfoliaceous 

 in those named Limnosipania in 



which the stamens are exserted and the leaves verticillate, whilst in 

 Sipanea proper the sepals are subulate, the stamens enclosed and 

 the leaves verticillate. They are annual or perennial herbs of 

 tropical America, with flowers in axillary and terminal, often 

 corymbiform cymes.
