G3tfc Some account of the Botanical Collection. [No. 7. 



being referred to by Steudel* and Endlicher.f Yet besides the two 

 species founded by Buchanan (loc. cit), I believe without sufficient 



grounds, on the Manga sylvestris prima et altera of Eumph,J 

 Buchanan's description of the Burmese Mariam is so different from 

 that of Boxburgh, as to lead to the suspicion, that under the name 

 Mangifera oppositifolia, two species will be found. 



Up to this time, I have met with three species, of which the 

 following are the distinguishing marks, independently of differences 

 that may exist in their hermaphrodite flowers and fruit.

X Rumph. under the head Manga sylvestris, does not mention the opposition 

 of the leaves, and though his figure, t. 27, might pass for Mangifera oppositifolia, 

 yet the leaves are by no means represented as being generally opposite, and the 

 aspect of the flowers again is rather that of a genuine Mango. 



§ This genus was first proposed, and its differences from Mangifera given, by 

 Messrs. Wight and Arnott under the name Cambessedea, for which, from its being 

 pre-occupied, Meisner has substituted Boueia.. But no sign or mark is appended 

 to indicate who were the original proposers of the genus, with whom the merit must 

 in most cases necessarily rest. It is one thing to glance over a complete Catalogue 

 of names, and ascertain which is pre-occupied, another to detect and define a new 

 group. Botanists have admitted certain conventional signs, which have been gener- 

 ally adopted, and would do well to admit signs of a most conspicuous character by 

 which the compiler may be known from the designer ; the Botanist who names after 

 examination and comparison, from him who names without having done either. Or 

 as suggested in the excellent rules for reforming Zoologic Nomenclature, p. 8, para. 

 4, now that communication is so rapid, it might be courteously left to the framer 

 of the genus to correct the error.

* The opposition of the leaves being characteristic of the genus, it becomes ne- 

 cessary to change Roxburgh's name.
