ON THE GAMBOGE TREE OF CEYLON.

plant sent pasted by Konig to Sir Joseph Banks, as one speci- 
men, I have ascertained to be made up of two plants, and very 
probably of two genera. The union was concealed by sealing 
wax. The portion in flower, and which agrees in structure 
with Murray's account, is, I have no doubt, the Xanthochy- 
mus ovalifolius of Roxburgh. Stalagmitis and Xanthochy- 
mus are therefore one genus, as Cambessedes has already ob- 
served, giving the preference to the earlier name of Murray. 
This, however, forms but a small part of the whole specimen, 
the larger portion being, I am inclined to think the same with 
your plant, of which I have seen, and I believe still possesss, 
the specimen you sent to Don.* The structure, however, of 
this great portion cannot be ascertained from the few very 
young flower-buds belonging to it. It approaches also very 
closely, in its leaves especially, to that specimen in Hermann's 
Herbarium, which may be considered as the type of Linnaeus' 
Cambogia Gutta. A loose fruit, pasted on the sheet with 
Konig's plant, probably belong to the larger portion, and re- 
sembles Gaertner's Morella." 
It appears then that the generic name of Xanthochymus 
must be dropped, and that the species which belonged to this 
genus must receive the appellation of Stalagmitis. It seems 
too, that the generic character of Stalagmitis by Murray, so 
far as regards the flower and the inflorescence, was not taken 
from the plant he meant to describe, but from the flowers of 
Xanthochymus ( Stalagmitis ) ovalifolius, which Konig had 
inadvertently fastened to it; and lastly, that it is not known 
that any specimens of the flowers of the plant which Murray 
meant to describe, at least not any sufficiently perfect for ex- 
amination, had been received in Europe, till those arrived 
which I owe to Mrs. Walker. The examination of these, 
proves that the plant is no Stalagmitis. It differs wholly in 
the number of the parts of the flower and cells of the fruit, in 
the structure of the calyx, corolla, and stamens ; in the ab- 
sence of intervening glands between the stamens, in the struc- 
ture of the leaves, in the appearance of the fruit, and in the 
* One of those received from Mrs. Walker.
