description. His remarks are as follows :—‘ La plante que nous 
venons de décrire nous parait étre la méme que l’espéce de 
M. de Candolle, autant du moins qu’il nous a été permis d’en 
juger, par le caractére peu détaillé que ce savant a donné de 
son espéce; et en effet notre plante de Cuba a bien le port et 
les caractéres extérieurs d’un Grewia; mais l’analyse que nous 
avons faite de sa fleur et particuliérement celle de l’ovaire nous 
_ ont fait découvrir dans notre plante des différences qui la dis- 
tinguent immédiatement du genre Grewia.” As will be seen from 
the key, and the remarks under Belotia mexicana and B. grewiae- 
folia, these two species differ in the shape, texture, indumentum 
and marginal teeth of the leaves, the inflorescence and the size 
of the flowers. 
The principal diagnostic characters of Belotia are the presence 
of nectaries at the base of the petals, and their absence on the 
androgynophore; the blue or violet, rarely white petals; the 
bilocular ovary with pluriovulate loculi; the loculicidal capsule, 
strongly compressed transversely to the septum; and the discoid 
ciliate seeds. In all these respects Belotia resembles the Old- 
World genus Trichospermum, which differs in having a pair 
inflorescence. As King pointed out,t the descriptions of T'richo- 
spermum published by previous authors were very inaccurate, 
with the result that it was assigned by Bentham and Schumann 
to the tribe Tilieae, instead of being placed by the side of Belotia 
in the Grewieae. In Hochreutiner’s revised classification of the 
Tiliaceae, however, both genera are correctly referred to the 
joideae-Grewieae. 
Misled by A. Richard’s reduction of Grewia mexicana to 
Belotia grewiaefolia, Turezaninov re-described G. mexicana as a 
supposed new species, Belotia Galeottii, from specimens collected 
by Galeotti (No. 4621) in Vera Cruz. Hemsley suggested that 
Grewia mexicana and Belotia Galeottii were conspecific, and 
Hochreutiner united them, but neither they nor any other authors 
seem to have suspected that Richard’s identification of the 
Cuban Belotia grewiaefolia with the Mexican Grewia mexicana 
was erroneous. 
Further confusion was introduced by Bentham’s reduction of 
Adenodiscus, Turcz., to Belotia,|| which was accepted by Hemsley 
and Schumann. Turezaninov founded the new genus and species,
