APOCYNACEAE. — TRACHELOSPERMUM 341 



Subgen. 4. LACHNOCARPUS Schneider, n. subgen. Descriptio in clavi. 



As stated before by King & Gamble, the two species referred to this subgenus 

 may be found to form a new genus,i but without having made a thorough study 

 of all the genera of the subfamily Echitoideae I am afraid to propose one. The 

 leaves and the shape of the flowers look very different from those of the other 

 species of Trachelospermmn, but the fiat (possibly not yet fullj^ ripe) foUicles I 

 have seen resemble to a certain degree those of the subgen. Axillanthus. See the 

 description of T. auritum Schneider.

King & Gamble mention the following species as a new unnamed one " which 

 approaches very near to this." According to their description T. Curtisii differs 

 mainly in its longer fruits (from 8 to 9 in. long); the cbrolla-lobes are described as 

 " obhquely triangular-spathulate, dentate at apex," and the tube is apparently a 

 little shorter than that of the following species, which has at least ten small scales 

 at the base of the sepals or sometimes more (or the scales are deeply divided), while 

 in T. Curtisii according to the author there are small subulate scales between the 

 lobes, that is, only five.

^ The authors say that in the Kew Herbarium T. Curtisii was placed with 

 Chonemorpha G. Don, and that in some respects it comes nearest to Epigynum 

 Wight. The type of Chonemorpha (Ch. macrophylla G. Don) is widely different in 

 the structure of the flowers, while that of Epigynum (E. Griffithianum Wight, Icon. 

 PI. Ind. Orient. IV. 4, t. 1308 [1850]), which I know only from Wight's plate, in the 

 structure of the flowers seems less different, but I have been unable to find a good 

 description of the fruits of this genus.
