The genus here described evidently belongs to Cyrtandracee, and is most nearly related to Antonia, in my 
account of which, given in the forthcoming first part of Dr. Horsfield’s Plante Javanice Rariores, 1 have en- 
tered at some length into the subject of the structure and affinities of Cyrtandraceæ, and the natural family (Ges- 
neriace@) to which I have referred that tribe. It is here, therefore, only necessary to add that Antonia, of which 
Wulfenia obliqua, Wallich Tent. Flor. Napal. vol. 1. p. 45. t. 35, may be taken as the type, was found in 18083, during 
Captain Flinders's voyage, near Coepang in the island of Timor, and being considered a very distinct genus from any 
then described, was first named Loxotis, but afterwards (in 1822), at the request of my lamented friend and fellow- 
traveller Ferdinand Bauer, was called Antonia, it being intended to introduce a figure of the Timor plant under that 
generic name in a wreath, ornamenting a bust or portrait of the late Baron Jacquin.—Brown.
