192 DR. J. D. HOOKER ON THE PLANTS 
Stipule parve, deciduz. Racemi pollicares et ultra, 12-20-flori, 
patentes. Pedicelli patentes v. decurvi, $ unc. longi, ebracteati. Ca- 
lycis tubus hemisphzerico-campanulatus, lobis brevibus latis obtusis. 
Petala parva, alba. Stamina 20-30, filamentis brevibus subulatis. 
Anthere oblongæ. Ovarium oblique ovoideum, in stylum crassum 
brevem subangustatum, stigmate magno, obliquo. 
Apparently identical with a species gathered in tropical East- 
em Africa by Dr. Kirk (Livingstone’s Expedition), at an eleva- 
tion of 3000 feet, at the foot of Mount Tshiradzuri and near Mun- 
gazi, of which I have fruit only. The latter is a much depressed 
sphere, near 4 inch in longest diameter, coriaceous and 1-seeded. 
The leaves are rather more deeply toothed in Mann's plant; but 
that is a most variable character amongst its allies.

4. UMBILICUS PENDULINUS, DC. 
Hab. Cameroons Mountains, alt. 7000-10,000 feet. (Fl. Nov.) 
Apparently the same as the European plant, but rather more 
fleshy in habit, of a deeper green colour, and with the bracts often 
but not always, foliaceous, and varying greatly in size and in form
