Kibessia DeCandolle. 
Kibessia verrucosa sp. nov. § Hukibessia. 
Arbor glabra, 4+—7 m. alta, ramis ramulisque teretibus; foliis 
chartaceis vel subcoriaceis, ellipticis vel oblongo-ellipticis, suboli- 
vaceis, nitidis, 15—22 cm. longis, utrinque subaequaiiter angustatis, 
basi acutis, 3-nerviis, apice obtuse acuminatis; inflorescentus 
axillaribus terminalibusque, subcymosis, 1—2 cm. longis; calycis 
tubo truncato, 6—7 cm. longo, 5 mm. diametro, perspicue verru- 
euloso, haud setoso, calyptra 5—6 mm. longa, acuta; petalis 4, 
obovatis, acutis, 6—7 mm. longis; fructibus obovoideis, truncatis, 
1 cm. longis, leviter verruculosis, verruculis subplanis, pentagonis, 
1.5 mm. diametro. 
An entirely glabrous tree 4 to 7 m. high, the branches and 
branchlets terete, smooth, usually brown, the ultimate branchlets 
about 2 mm. in diameter. Leaves chartaceous to subcoriaceous, 
elliptic to oblong-elliptic, subolivaceous, shining on both surfaces, 
the lower surface somewhat paler than the upper, 15 to 22 cm. 
long, 6 to 11 em. wide, subequally narrowed to the acute and 
prominently 3-nerved base and to the blunt-acuminate apex ; midrib 
and basal nerves somewhat impressed on the upper surface, very 
prominent on the lower surface, the longitudinal nerves reaching 
the apex of the leaf, a very faint pair of marginal nerves usually 
present, situated 1 to 2 mm. from the edge of the leaf, these not 
more prominent than are the primary reticulations ; p petioles rather 
stout, 5 to 8 mm. long. Inflorescences axillary and terminal, 
solitary or fascicled, subcymose, 1 to 2 em. long, few-flowered. 
Calvx tube cup- -shaped, truncate, 6 to 7 mm. long, about 5 mm. 
in diameter, rather conspicuously verrucose but not at all setose, 
the conical ‘apical portion formed by the wholly united sepals 5 
to 6 mm. long, acute, deciduous. Petals apparently pale-blue, 
obovate, acute, inequilateral, 6 to 7 mm. long. Stamens 8, the 
anthers about 2.5 mm. long, inappendiculate. Fruits somewhat 
obovoid, truncate, about 1 cm. long, slightly verruculose, the ver- 
ruculae plane, scarcely or not at all elevated, pentagonal, about 
1.5 mm. in diameter. :

flowering 1 in November, fruiting in August, October, ‘and February. 
in forests at low altitudes. A species in its calyx characters ap- 
parently approximating Aibessia teysmanniana Cogn., but with 
entirely different vegetative characters. It is easily recognizable 
by its elliptic to oblong-elliptic leaves which are subequally narrow- 
ed at both ends and by its verruculose calyx tube which is not at 
all setose, the verruculae being plane or nearly so, sometinres 
shghtly elevated in their central portions.
