In Bamnacantlmis, spinous shrubs of China, Japan and Bengal, the 

 flowers are the same in construction with ovarian cells and stylary 

 divisions 2-4. The ovule 



also is descending ; and, as Mitcheiia repens, 



in Frismatomeris and for the 

 same reason, the embryonic 

 radicle is inferior. The 

 flowers are solitary or ge- 

 minate. They have the 

 same organization as in 

 Mitcheiia (fig. 294), gene- 

 rally referred to another 

 series and inhabit, one 

 Japan, the other North 

 America. They are peren- 

 nial climbing herbs and 

 perhaps only a section of 

 Damnacanthus. The sti- 

 pules are membranous, not 

 spinous,in the trueilf lYc/i^^ZZrt , 

 and the axillary or terminal 

 geminate flowers have their 

 ovaries united in a common 



receptacle, instead of being independent like those of Damnacanthus : 

 a character observed in various honeysuckles.^ 



Cremaspora (fig. 295), with Alhertay has been ranged in a separate 

 tribe (Alhertecc) of Ruhiacccc, with solitary descending ovule, the 

 corolla of which is contorted instead of being valvate. Otherwise, 

 their resemblance to Canthium is very close. " The stamens are 

 inserted in the throat of the corolla, and the fleshy fruit encloses one 

 or two descending and albuminous seeds. In the true Cremaspora, 

 the flowers are generally pentamerous ; the style is not divided, and 

 the horny perisperm is continuous. In those named Pohjsphceria, 

 the flower is in four or five parts ; the style is ordinarily divided into

1 In. Bichilinthe, of Ceylon and Borneo, there 

 are, not two but, a greater number of flowers 

 forming a false capitule. The corolla is curved 

 and subbilobed. Sahmannia and Phialanthus, 

 American shrubs, have also many- flowered 



cymes ; but they are axillary. The corolla is 

 valvate or slightly imbricate. The anthers of 

 the former are basifixed, of the latter, dorsifixed. 

 All have a descending ovule with dorsal 

 raphe.
