or in spikes, simple or little ramified at the base, axillary and 

 terminal. The corolla is valvate and the fruit septicidal. 



Cosmibuena gives name to a subseries ( Gosmihiienece) in which the 

 flowers have the same general organization as in the preceding types, 

 and the capsular fruit also contains winged seeds, but with a contorted, 

 not valvate corolla. It comprises equally old-world types and American 

 genera. They are : Cosmibuena, from tropical America, having large 

 terminal flowers, solitary or in three-flowered or compound cymes, 

 with a corolla of which the torsion is sometimes from right to left, 

 sometimes from left to right, an elongate style, claviform and bifid at 

 the summit, and a septicidal fruit ; Ferdinandtisa , trees or climbing 

 shrubs from the Antilles and the east of South America, with long 

 and narrow corolla, the limb of which, somewhat unsymmetrical, is 

 divided into four lobes resembling a perianth slightly bilabiate, four 

 unequal stamens, two few- or many- seeded ovarian cells, a septicidal 

 capsule and terminal compound clusters of cymes; Bavnia, from 

 Costa-Kica, an epiphytal shrub with 5, 6-lobed contorted corolla, an 

 ovary of two multiovulate cells, the fruit of which is unknown and 

 the habit said to be that of JUschynanthiSy with subsessile flowers in 

 terminal three-flowered cymes; Capiroiia, a Brazilian tree with 

 coloured bark easily separable from the wood, having large opposite 

 oboval leaves, compound terminal cymes, 5, 6-merous flowers, some- 

 what irregular or regular; contorted corolla, the throat of which is 

 glabrous, staminal filaments united at the base, and capsular, 

 septicidal, polyspermous fruit, similar to that of Cascarilla^ 



In the old world this group is equally represented by four genera : 

 Dolicholohkim, shrubs of the Viti isles, whose axillary flowers.
