The generic character of Crossopteryx may be completed as 
follows : 
Calycis limbus 5-partitus, lobis dentiformibus erectis. Corolla 
hypocrateriformis, extus villosa, tubo tenui, limbo 5-lobo, 
laciniis oblongis. obtusis sestivatione imbricatis, fauce intus 
nuda. Stamina ad apicem tubi inserta, antheris oblongis 
apiculatis plus minus exsertis. Stylus filiformis apice clavato- 
bilobus. Ovarium biloculare, placentis dissepimento adnatis, 
` 9vulis imbricato-appressis. 
Heudelot’s Senegambian collection contains specimens, both 
in flower and fruit, of C. Kotschyana, a species which extends 
into Nubia, and specimens, in flower only, of a new species. 
In Don’s Sierra Leone collection is an imperfect specimen, 
in fruit only, of a plant belonging to the tribe Cinchonee, which 
it is impossible to determine for want of flowers, more especially 
as from the capsules it would appear to form a new genus allied 
to Cascarilla or Remijia.
