To the latter tiilie Coptasapelta belongs, which genus in Genera 

 plant, was placed among the former, a mistake already corrected 

 by King and by Schumann. 



The latter places (Pflanzenfani. IV, 4 p. 42 and 48) Coptasapelta 

 immediately beside Crossopteryx, an African genus, 1 could not 

 examine, to which only one species or group of species belongs, 

 living on the barren Campos of Abyssinia — till lower Guinea. On 

 comparing the detailed description Oliver gives of this genus, I 

 found, that nearl}' all more oi' less important characteristics given 

 by 0. are also applicable to Coptasapelta ; only two are lacking, 

 viz. Stigma clavatum bilobum and t u b u scor ol 1 ae graci- 

 lis, limbus parvus. The important characteristic of the length 

 of the stigma however is present. L/;u/t!«/o/«M however has a stigma 

 clavatum and a tubuscorollae gracilis, so that only the bilobular 

 stigma forms an important difference. This points to a close relation 

 between these two genera, especially between Crossopteryx a,n& Lhi- 

 deniopsis, on account of the shrubby, xerophilous habit. 



The leaf-nervature of Crossopteryx is not fully described, but the 

 leaves have the same shape; they are laiger than with mos^i Copto- 

 sapelia-s\)ecies, but equal to those of C. flnvescens. The close rela- 

 tionship of the two genera cannot be doubted. I could not find 

 any striking points of similarity with other genera of the tribe of 

 Cinchoneae, of which but a small number of species occur in the 

 old world. The most characteristic peculiarity, the structure of the 

 stigma does not occur in any other genus of this tribe. 



Remarkable however is the resemblance of pistil and corolla in 

 species of two genera, belonging to the bacciferous Rubiaceae with 

 many ovules, viz. Tarenna Gaehtn. (syn. Stylocoryne, syn. Webera), 

 which has given rise to a peculiar synonymy. 



The name Stylocoryna, given in 1797 by Cavanii.i.es to a species 

 from the Liu-lchiu-Arcliipelago, is formed from the words arv).oq: 

 pillar and y^oQvvn: club, briefly denoting the structure of the pistil 

 of Coptosnpeltn, as described above. Hookek referred this species to 

 the genus Rattdia Linn., so that the characteristic generic nanie 

 was lost. In 1834 Wight brought it up again in the form of 

 Stylocoryne (independent of Cava7iilles?) for a plant from Ceylon 

 new to him, viz. St. covymbosa Wight, which again showed this 

 peculiar shape of pistil. Neither could this name be kept, as the 

 same species had previously been diagnosed by Gaertnkr (in 1788) 

 as Tarenna zeylanlca, wich latter name of course enjoys the pre- 

 ference. The first generic name however had been accepted by 

 various authois (Roxburgh, Blume, a.o.) and Blume was the first to
