344 Mr G. Don's Account of new or rare Plants 
othci species ; * Cassia conspicua , new, like C. fstula , the 
Monkey Dium-stick ^ree of the colonists; ^ Arum compres- 
sum, new, bulb large, round, and flat; *Aletris 0 several species ; 
Pavetta , two or three species; Strophanthus sarmentesus ; *Ble- 
tia Guinense , new, like B. verecunda , but larger ; H amianthus 
midtiflorus , with many others. All the fruit-trees of Sierra 
Leone are likewise interesting, but are now mentioned in the 
4th Part of the 5th volume of the London Horticultural So- 
ciety's Transactions, where there is a figure of * Sarcocephalus 
esculentus , the Sierra Leone Peach. 
Professor Afzelius of the University of Upsal, who resided in 
the colony of Sierra Leone for several years, formed an exten- 
sive collection in every department of natural history. It is 
much to be regretted, that so distinguished a naturalist should 
not have given his discoveries to the world soon after his return 
to Europe. Among his collection of plants in the Lambertian 
Herbarium, are specimens of all those noticed in this paper. The 
examination of this collection proved of great benefit to me.

The C. comosum , is a beautiful climbing shrub, and attaches 
itself to other shrubs which it grows near : if growing in a place 
clear of other plants, it supports itself, and in these cases as- 
sumes a conical form. The younger branches are pubescent. 
The leaves are opposite, large, oblong, pointed, entire, smooth, 
and at the base somewhat cordate, upon short footstalks. The 
panicles are brachiate, composed of numerous, elongated, oppo- 
site or verticillate spikes. The flowers are crowded or tufted, 
about twice the size of those of C. purpureum ; of a deep scarlet 
colour. The seed-vessels, before they be perfectly ripe, are of 
a pale red, which makes a striking contrast. This plant is very 
common in the low lands as well as in the mountains of Sierra
