posible, however, that the discovery of other species, or a better 
knowledge of the present one, may hereafter render it necessary 
to unite Cremaspora with Kraussia.

The Senegambian collection contains also a second unpub- 
lished species, with nearly sessile leaves. The genus has the 
imbricate æstivation and terminal inflorescence of Irora and 
Pavetta, but the ovules are attached much higher up in the 
cells, so as to be nearly pendulous, besides the slight differences 
in the flower pointed out by De Candolle.

The Coffee plant appears to. be very variable in the size and 
form of its leaves. A specimen of Vogel’s, cultivated at Cape 
Palmas, (with the observation that it is wild in Monrovia), has 
the leaves 10 inches long and 4 inches broad. In Don’s C. ste- 
nophylla, from Sierra Leone, they are 4 or 5 inches long, 
by about li broad, with rather long points. Other specimens 
are intermediate, and some even have them still narrower than 
Don’s. The genus, confined to its proper limits, has the æsti- 
vation and placentation of Ixora and Pavetta, with an axillary 
inflorescence and a peculiar seed. 
` The Coffea microcarpa, DC., from Senegambia, if a true 
Coffea, is unknown to me.
