seed itself erect, yet no inversion takes place, but only an elongation upwards, the foramen of the testa (micropyle) 
being, as Dr. Brown supposes, situated at the lower or free extremity. 
There is little doubt that Rumphius's Mangium album (Herb. Amboin. vol. 3. p. 115. t. 76.) is the same species 
as our tree, although so acute an observer as my late friend Mr. Jack thought differently, (Malayan Miscellanies, 
vol. 2. n. 7. p. 98). 
The vitality of the seed is so great that it never fails germinating long before the fruit falls off; and it often happens 
that an infant plant is seen protruding its tender leaves and roots through the integument of the fruit while yet 
attached to the tree. Å similar phænomenon frequently occurs in the fruit of Brownlowia elata, which ripened in 
the Calcutta Garden for the first time in September 1825. At the time I furnished the notices in the Botanical 
Register, vol. 17. n. 1472. on this fine tree, I had mislaid my carpological memorandums : having since found them, 
I introduce them here.

I have not seen the flowers of this shrub. The structure of its fruit, which I was prevented from noting down at 
the time I found it, corresponded entirely with that of Willoughbeia edulis (Roxb. Corom. Plants, vol. 3. t. 77 J to 
which plant, indeed, our shrub comes very near. The presence of tendrils in this as well as in the above-mentioned 
species, is very remarkable among Apocynee. Dr. Blume long ago noticed them in his valuable Bydragen, 
p. 1024, and they seem to corroborate the generic difference between the two genera of Aublet, on which Schreber 
(Scopoli according to Sprengel, ) founded his Willoughbeia. One of these genera, namely Pacuria, seems to have a 
tendency to produce similar tendrils, and is certainly nearly allied to, if not identical with, the genus to which our 
plants belong, and for which the name Ancylocladus might, if required, perhaps be applicable. I have found a plant 
at Singapur, without flower or fruit, which, from the presence of the tendrils, and the general habit, probably belongs 
also to this group, and which I have called Willoughbeia coriacea in the Catalogue of the Honourable Company’s 
Herbarium, n. 1620. It has oval-oblong coriaceous leaves, ending in a short blunt acumen, with prominent parallel 
nerves underneath, and seems to differ from all the species enumerated by Dr. Blume.
