540 PENTANDRIA MONOGYNIA/ Alyxiit, 



Anona —Seed conform to the berry. Integument single, thin, but 

 hard and elastic, approaching to nuciform ; from the middle of 

 the inside a vertical lamina projects one third into the seed, then 

 divides and proceeds in opposite directions, like the receptacles in 

 C/tironia (see Gee>t. sent, ii. t 1 14.) to these the perisperm is attach. 

 ed. — Perisperm conform to the seed, in the centre a thin portion 

 thereof forms an entire sac, or cavity for the embryo, the rest is divid- 

 ed into innumerable, diverging, fleshy, cuneiform lobes; colour 

 greenish, becoming white, texture fleshy. — Embryo erect, straight, 

 nearly as the perisperm. Cotyledons lanceoiar. Radicle sub-cy- 

 lindric, inferior. 



Obs. I am inclined to think that this may be Forster's Gynopo* 

 gon steJlatum, or another species of the same genus; (now Alt/xia ; see 

 Brown's Prodromus, Nov. Holl. \.p. 469,) and I conclude he had not 

 an opportunity of making himself acquainted with the carpology of the 

 genus. Until I met with the fruit 1 considered it a Ranwolfia; 

 but am now satisfied it cannot belong to that family. To what na- 

 tural order? Apocyneae?

€. A. lucida, Wall. 



Younger brandies quadrangular, pubescent. Leaves opposite,' 

 tern and quatein, obovate, acute, sometimes obtuse, coriaceous, 

 shining above, smooth.— Corymbs axillary, pubescent, equalling the 

 petiols, tnchotomous. Rractes linear, villous. 



I found it on swampy shores among Mangrov33 at Singapore, in 

 ■flower and fruit in October. 



A ramous, perfectly smooth, twining shrub. Stem and branches 

 covered with smooth, shining, bruwn, or mahagony-coloured bark. 

 Branches opposite or tern, sometimes quatein, slender, brown, alter- 

 nately and acutely four-cornered between the insertion of the leaves, 

 where they appear somewhat jointed ; a little pubescent and scabrous 

 w bile young.— Leaves mostly opposite,on the young branches quatein,
