Anonal polycarpa, DC. Syst. Veg. i. 499. Coelocline polycarpa, A. DC. Mem. Anon. 32. 

 Sierra Leone [Afzelius) ; on the Sugar-loaf Mountain, at an elevation of 2000 feet (Dr. Daniell). From 

 specimens in the British Museum. 



10. Xylopia, Linn. ; Benth. et Hook. f. Gen. PL 28. 

 A considerable American genus, with a few Asiatic species besides the subjoined 

 African ones. The floral characters are nearly those of Anona and Melodoruni, differing 

 chiefly in the very narrow long or tapering petals and in the remarkable concave almost 

 cup-shaped torus, the outer portion, which bears the stamens outside and encloses the 

 gynaecium, falling off as soon as the flowering is over, leaving the carjjels on an appa- 

 rently convex torus. The fruit is nearly that of Unona. In iT. acutijlora and 2)arviflora 

 the seeds have no arillus, which occasioned their generic separation by A. DeCandolle 

 under the name of Coelocline ; but in X. (Bthiopica that arillus is very small ; and in no 

 Anonaceee does its presence or absence ajjpear to be of generic value.
