branching shrub, on another as a tree, which he states to be 
cultivated. 
The Senegambian collection contains a new species of the 
South African genus, Piptolena, so remarkable for the form 
of the calyx, with its numerous glands, elegantly arranged in a 
a double row withinside.

pollicaria, latitudine varia, venis paucis a costa divergentibus, 
venulis inconspieuis. Petioli ad caulem in vaginam expansi, 
et linea transversali connexi. Pedunculi e dichotomiis soli-

vix pollicares unifloros sub flore incrassatos divisi. Calycis 
lobi inzquales, 3-5 lin. longi, obtusissimi, glandulis ad

Ovarium et genitalia Tabernemontane. 
I describe this plant from Heudelot’s Senegambian specimen. 
Vogel’s, from Sierra Leone, has every appearance of belonging 
to the same species, although the leaves are rather narrower. 
There is no corolla ; but two persistent though shrivelled calyces, 
enclosing imperfect ovaries and the remains of some fruit- 
stalks, show that, if not the same species as Heudelot’s, it is 
closely allied to it. Vogel states it to be a handsome tree, with 
the aspect of a Citrus and a milky juice, ie

corollæ tubo longiusculo paullo infra medium ventricoso con- 
torto et staminifero.—Grand Bassa, Vogel. ; 
Frutex arborescens, succo lactescente, affinis 7. longiflore et
