458 FLORA NIGRITIANA. 
uniflorus, e centro fasciculi (ex apice ramuli) foliis subbrevior, 
sub calyce incrassatus, glaber. Flores glabri. Calycis la- 
cinie lineam longz, membranacez, striate. Corolle tubus 
calycem æquans, laciniz duplo longiores (patentes?) ; ligule 
faucis laciniis breviores. 
The flowers on the specimen are so few and so much crushed 
in drying, that I am not certain of having very accurately 
ascertained their structure. They appear to be allied in many 
respects to those of Pentasacme and Barrowia, although the 
very twisted æstivation of the corolla shows more affinity to 
some of the subdivisions of Gymnemee.

The list of W. Tropical African Asclepiadee hitherto known 
is closed by two species of Boucerosia, B. acutangula, Dene., 
and B. Decaisneana, Lem., both from Senegal, and by two 
doubtful plants, the Pergularia sanguinolenta, Lindl., from 
Sierra Leone, and an incomplete specimen of Don’s from Sierra 
Leone.

There are three specimens, belonging perhaps to three, or 2j 
any rate to two different species, but none of them in a state 
actually to determine. The one, gathered at Attah, is described 
by Vogel as a tall climber, with an apple-shaped, glaucous 
fruit ; it is in leaf only, with the remains of fruit-stalks. I 
should have taken it to be the S. scandens, Schum. et Thonn. # 
Guinea plant, but that the racemes or panicles appear to have 
been very short and few-flowered. Some of the peduncles are 
converted into hooks. A second specimen, in leaf only, and 
without any precise station, is very much like the first, but at 
very blunt leaves. The third specimen, gathered at Patteh, 18 
in leaf only; these leaves are shorter and rounder than in the 
two others, and here and there are a pair of opposite spines,
