Benzonia. | LXX. RUBIACEEZ (HIERN). 247 
globose, lobes concave, cup-shaped, rather acute. Stamens 5, sessile at the throat, 
alternate with the corolla-lobes; anthers triquetrous, convex on the back, flat on the 
sides. Disk depressed, subperforated. Ovary inferior; style filiform, nearly the 
length of the corolla ; stigma ovate-globose, rather acute, longitudinally marked with 
6-7 furrows.—Bramches woody, terete, papillose-pilose towards the extremities. 
Leaves opposite, coriaceous; stipules interpetiolar, lanceolate, acute. Peduncles 
axillary, solitary, dichotomous. Flowers small. 
A genus peculiar to this Flora, and quite unknown to me; the description of it 
as well as of the species, is taken from Schumacher. 
1. B. corymbosa, Schum. 1.c. p. 114. Leaves ovate-oblong, acuminate, sub- 
cordate at the base, veiny, shining, glabrous, paler and glaucous beneath, the midrib 
and the younger leaves also above rusty-pilose and ciliate, 3in. long; petiole 2 in. 
long, furrowed above, hirsute; stipules membranous, spongy at the base, glabrous. 
Peduncles about 4 in. long; pedicels bifid, corymbose, hirsute, less than 7s in. long. 
vile hirsute ; teeth pilose-ciliate. Corolla-tube } in. long. Ovary closely girt by 
the calyx.

_ The following genus is also unknown to me; it was referred by its author to the 
neighbourhood of the shrubby Boraginex, but it certainly appears to belong to Ru- 
biacex, though I am unable to fix its position in the Order. 
80. Leprrocon, G. Bertol. in Mem. Accad. Bologn. iv. p. 539, t. 21 (1853). 
Calyx turbinate, adnate below to the ovary; limb free, 5-cleft. Corolla monope- 
talous; tube short, inside at the middle furnished with 5 densely bearded scales ; 
limb 5-partite ; segments imbricated (in the figure) or perhaps contorted. Stamens 
5, included, inserted on the corolla-tube a little above the scales, alternating with the 
corolla-lobes; filaments very short ; anthers oblong-lanceolate, erect, obtuse, subcor- 
date at the base, 2-celled. Epigynous disk flattish, with an annular margin. Style 
Solitary ; stigma bifid; branches oblong, thick, obtuse. 
1. L. obovatum, G. Bertol./.c. A shrub. Stem terete, alternately branched, 
glabrous except the branchlets which are pubescent at the apex. Leaves obovate, 
rounded at the apex, quite entire, shortly petiolate, glabrous or sparingly pilose, pu- 
bescent on the midrib and lateral veins, $-14 by $-$ in.; stipules pubescent, shorter 
than the leaf ; stipules short, broad, ovate, ferruginous-pilose, deciduous. Peduncles 
terminal, 1-flowered, solitary or in pairs, pubescent, as long as the flowers, 3 in. 
Calyx pubescent ; lobes spathulate (lanceolate in the figure), scarcely acute, narrowed 
at the base, shorter than the tube. Corolla densely pubescent ; tube short ; beard 
white, shining ; lobes obovate, obtuse, longer than the tube. Anthers yellowish. 
Style thicker below. 
Mozamb. Distr. Inhambane, Fornasini. 
There are in the Kew museum specimens of wood and bark, and in the herbarium 
4 leafy shoot without either flower or fruit, of a plant sent by Dr. Kirk from Shu- 
Panga and also from the neighbourhood of Senna, which is known in Mozambique by 
© name of Mukundukundu ; the trank is about a foot in diameter, and is used for 
small canoes ; it is very bitter and said to be employed in case of fevers. It appears 
to belong to Rubiacew and may be a species of Mitragyne; flowering and fruiting 
Specimens are wanted.
