Ås there is still a doubt whether Dunal's Xy/opia undulata is a real Unona or not, I have retained the specific name 
given to our shrub in Roxburgh's Zortus Bengalensis. In my Catalogue of the Honourable Company's Herbarium 
I call the species Unona Rowburghiana (n. 6423.), which name I propose for adoption, in case the old one should 
require to be changed. I have never seen the fruit, but the habit of the plant is so much like that of the genus to 
which I have referred it, that I have not hesitated to remove it thither. I am not quite certain whether the 
Sillet specimens may not belong to a distinet though nearly allied species, remarkable on account of the singular 
manner in which the sepals enlarge, immediately after the petals have fallen off. I cannot allow this opportunity 
to pass, without rendering my thanks to Dr. Blume for the great advantage I have derived from his excellent 
Flora Javæ in the arrangement of the plants belonging to the difficult family of Anonacee in the herbaria under 
my charge. 
Plate CCLXV. The detached flower exhibits its state of perfect expansion immediately before the petals fall off.
