ST TE ee 
Although we have referred this plant to the genus Cephaélis, it is only as a temporary measure, till its ripe fruit 
shall have been produced. ‘There is every reason to believe it will then forma new genus in Rubiaceae, allied on 
the one hand to Psychotria, and on the other to Cephaélis ; but agreeing better with the latter than with the former 
in mode of inflorescence, and equally distinguished from either by its great, funnel-shaped, usually unequal calyx. 
Even with our present imperfect knowledge of this plant, we are not sure it would not have been better to have pro- 
posed it as a new genus, than to have referred it to an old one in which it cannot eventually remain ; even if its cha- 
acters depended solely upon the peculiarity we have just noticed. We, however, have felt unwilling to do this in so 
difficult and extensive an order as Rubiacee ; and have preferred attaching to it as a specific name, a term which in- 
dicates a character altogether at variance with those of the other species, all of which are said to have a very minute 
calyx. We have diligently looked over all the Rubiaceous plants to which we have had access, and also M. de Jussieu’s 
late most learned monograph of the order, without discovering any traces of a plant to which this can be referred. 
It is at present uncommon in our gardens. Mr. Cattley’s noble collection contains the plant from which our draw- 
ing was taken : and we have also observed it in the Kew Garden, where we were informed it was a native of Brazil.
