by the presence of a style and stigmatic branches. The exact nature of the corona and 

 of the "glands of the disk" or outer staminodes, is doubtful, and requires an examine 

 tion of fresh flowers in all stages of their development for its full elucidation.

1. M. senensis, Mast. A climbing shrub with terete or obscurely 

 angular, smooth, sulcate, striated branches. Leaf-stalks shorter than 

 the blades, channelled on the upper surface, twisted, deflexed and 

 having* two sessile glands on each side at the apex ; leaf-blades deeply 

 palmately lobed, lobes membranous, smooth, glaucous beneath, oblong, 

 obtuse, tapering at the base into a short petiolule, entire or irregularly 

 pinnately lobed, midrib prominent on the under surface; 3-5 in. long, 

 1-12 in. wide, the central lobe largest. Stipules minute, awl-shaped, 

 caducous. Peduncle axillary, as long as the leaf, bearing a few- 

 flowered cyme in the middle and prolonged into a tendril. Male 

 fl. : Calyx f in. long, limb divided into 5 entire linear-oblong di- 

 visions. Petals membranous, entire, their long stalks adherent 

 for the greater portion of their length to the inner surface of the 

 calyx-tube, included. Corona of 5 short flat capitate filaments, alter- 

 nating with the petals. Stamens 5, filaments monadelphous at the 

 base, above free, thread-like; anthers innate, linear-oblong, obtuse, 

 2-lobed. Rudiment of the pistil minute. Ovary (according to Klotzsch) 

 stipitate, oblong, 1 -celled ; ovules numerous, on 3 parietal placentas ; 

 style very short ; stigmas 3, large, reniform. Fruit stipitate, stipes 

 encircled with the persistent remnant of the calyx, oblong, obtuse, 

 smooth, 2-3 in. long, 3-valved, valves coriaceous, orange-red, smooth. 

 Seeds compressed, lenticular, pitted, surrounded by a membranous aril.

Mozamb. Distr. Zambesi, Senna, and elsewhere, Dr. Kirk ! 



Although I have not seen perfect female flowers of this species, I have no doubt that 

 it should be referred to Modecca* Klotzsch described the petals as staminodes, and 

 apparently had not seen the fruits. In the short style it approximates to the Indian 

 species of the section Microbltpharis. The staminal tube is likewise longer than in 

 the other African species. Dr. Kirk describes the petioles as exceeding in thickness the 

 branch that bears them, but this is not apparent in the dried specimens. 



2. M. Welwitschii, Mast. A climbing undershrub with slender, 

 cylindrical, sulcate, flexuose branches. Leaves membranous, glaucous, 

 3 in. long, 3J in. wide, palmately 5-lobed, lobes oblong-lanceolate, 

 tapering at the base into a short stalk, 1 -nerved, arch- veined, the two 

 lower lobes smallest, directed downwards, the two median ones ascend- 

 ing, the middle or terminal lobe much the largest and often 3-lobulate,
