Ponca, seu Poneu, p. 73. tab. 35. 
With his usual negligence respecting names, Rheede says in the letter-press 
that the Brahmans call this tree Helay, and in the plate that they call it Calo 
Dumpu. In one place he says that the Portuguese call it Massao spinosa, and 
in another, Tsjaka do Mato; and on this resemblance Commeline calls it Jaca 
minor sylvestris Malabarica. I must, however, say that the figure of the fruit, 
as represented dissected in the plate, has little resemblance to an drtocarpus, 
and seems to be composed of a number of one-leaved calyces, each terminated 
by spinescent divisions ; nor is there any appearance either of sexual organs or 
seed. 
Plukenet in my opinion was little more fortunate than Commeline, when he 
compared the Ponga (Mant. 42.) to his *Cenchramidea arbor pilulifera, fructu 
tuberculis ineequali, ex granulis coniformibus in orbem glomerato, non capsularis" 
(Alm, 92.; Phyt. t. 156. f. 3.), which has serrated leaves, and from its generic 
name Cenchramidea, as well as from its habit, should be a Bubroma. 
The elder Burman erred much further in considering the Ponga as the same 
with the Cussambium of Rumphius (Herb. 4mb. i. 157.), an opinion which it is 
strange the accuracy and acuteness of M. Lamarck (Enc. Meéth. ii. 230.) should 
have allowed to be of any weight; for although he notices that the plants were 
essentially different, yet, giving too much credit to the opinion of Burman, he 
takes each leaflet of the Cussambi for a leaf, the leaves of the Ponga being 
simple, while those of the Cussambi are pinnated. 
M. Poiret (Enc. Méth. v. 563.) is more fortunate in considering the Ponga 
as a Papyrius or Broussonetia, which I am inclined to think is actually the 
case; and I therefore suppose the figure of the dissected capitulum to repre: 
sent the female flower before the singular receptaculum has elevated the seed. 
In the woods near Goyalpara, on the south side of the Brahmaputra, I have 
found, bearing ripe fruit, a species of this genus much in its foliage resembling 
the Ponga; but its fruit is much too small, and supported on too long foot- 
stalks to admit of its being the same species. In the catalogue of specimens 
presented to the library at the India House I have called it Papyrius seu 
Broussonetia integrifolia, a name equally applicable to the Ponga ; but in order 
to distinguish them I shall here describe the plant, which I have seen.
