A moderate-sized tree. Branchlets tomentose. Leaves 

 alternate, pinnate ; leaflets from seven to nine, alternate, 

 short, pedicelled, elliptic-ohlong, broader above, rounded 

 towards the point, and terminating in an obtuse acumen, 

 entire, very smooth ; nerves pubescent beneath ;.from seven 

 to ten inches long. The young leaves are pubescent on 

 the under surface. Stipules none. Racemes springing from 

 the trunk and naked branches, sometimes solitary, some- 

 times fascicled, at first suberect, but drooping afterwards 

 by the weight of the fruit ; tomentose : flowers sessile, 

 alternate, solitary, tribracteate at the base. Calyx deeply 

 five-parted ; segments round, concave, imbricated. Corolla, 

 five-petalled, yellowish, a little longer than the calyx ; petals 

 subrotund. Staminiferous tube sub-globose : mouth nearly 

 entire ; anthers ten, inserted within the tube. Ovary five- 

 celled ; cells containing a single or double ovulum attached 

 above to the inner angle. I have never observed two distinct 

 ovula; but the single one is often marked with a furrow, 

 as if composed of two united together. Style short, thick, 

 columnar, ten-furrowed. Stigma flat, obscurely radiated. 

 Berry of a yellowish colour, cortical, seated on the persistent 

 calyx, oblong-ovate, or oval, slightly tomentose, five-celled 

 five-seeded. Seeds enveloped in a white semi-transparent 

 pulpy tunic or aril, exalbuminous ; cotyledons solid conform to 

 the seed, unequal, irregularly transverse, peltate ; the short 

 pilose radicle being inserted into their centre. Two seeds 



* I am not yet certain whether there is a specific difference between the 

 Lanseh of Malacca and to Dookoo of the same place. — W. J.
