A considerable American genus, with a few Asiatic species besides the subjoined 
African ones. The floral characters are nearly those of Anona and Melodorum, 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 
gynsecium, falling off as soon as the flowering is over, leaving the carpels on an appa- 
rently convex torus. The fruit is nearly that of Unona. In X. acutijlora and parvijlora 
the seeds have no arillus, which occasioned their generic separation by A. DeCandolle 
under the name of Cceloclme ; but in X. cethiopica that arillus is very small ; and in no 
Anonacese does its presence or absence appear to be of generic value.
