Bt'uzonia.] lxx. rubiace^ (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 

 leug-th of the corolla ; stigma ovate-globose, rather acute, longitudinally marked with 

 6-7 furrows. — Branches 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.l. c. p. 114. Leaves oa ate-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, 3 in. long ; petiole ^ in. 

 long, furrowed above, hirsute ; stipules membranous, spongy at the base, glabrous. 

 Peduncles about ^ in. long ; pedicels bifid, corymbose, hirsute, less than ^ in. long. 

 Calyx 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 Boraginese. but it certainly appears to belong to Ru- 

 biaceae, though I am unable to fix its position in the Order. 



80. Lepipogon, Gr. Bertol. in Mem. Accad. Bologn. iv. p. 539, t. 21 (1853). 



Calyx turl^inate, adnate below to the ovary ; limb free, 5-cleft. Corolla monope- 

 talous ; tube short, inside at the middle furnished with 6 densely bearded scales ; 

 limb 5-partite ; segments imbricated (in the figure) or perhaps contorted. Stamens 

 6, 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. It, obovatum, G. Bertol. Z. 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, |-1^ by ^-* in. ; stipules pubescent, shorter 

 than the leaf; stipules short, broad, ovate, ferruginous-pilose, deciduous. Peduncles 

 terminal, l-flowered, solitary or in pairs, pubescent, as long as the flowers, f in. 

 Calyx pubescemt ; 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.

There are in the Kew museum specimens of wood and bark, and in the herbarium 

 a 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 

 the name of Mukundukundu ; the trunk 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 Eubiaceae and may be a species of Mitragyne ; flowering and fruiting 

 specimens are wanted. 



The fifth new genus of Rubiacese mentioned by R. Brown in Tuckers "Congo," p. 

 448, as intermediate between Rubiacese and Apocynaceae, is Mostuea, F. Didr. (1854) 

 i. e. Leptocladus, 01iv.(1864), and is now placed in Loganiaceae.
