Mozamb. Distr. Zambesi, Peters ! 



Flowering specimens of a plant gathered by Barter on the Niger agree with this 

 description, except in the flowers, which are borne in slender spikes. The leaves als6 

 are not pubescent, but sparingly lepidote on both sides.

 or 3 in a whorl or alternate, 2-3 in. long by 1— 1J in. broad, obovate- 

 oblong, cuspidate, cinereous, pellucidly punctate, pubescent. Flowers 

 crowded at the ends of the spikes. Calyx-limb infundibuliform. Petals

26. C. altum, Perr. ; DC. Prod, iii. 20. Small tree, 20-25 ft. ; 

 young branches puberulous. Leaves ovate-elliptical, acuminate, 3 in.

 Prod. I.e. 21. 



Upper Guinea. Nupe, Barter! Senegal! 



C. micranthum appears to me to be a small variety of C. altum, differing from it 

 only in its smaller leaves and fruit. 



27. C. laxiflorum, Welw. mss. Tree. 25-35 ft. high. Leaves oppo- 

 site or alternate, petiolate, oblong-elliptical, shortly and abruptly 

 acuminate, about 5 in. long and 2 in. broad, glabrous above, covered 

 beneath with large isolated ruby-coloured scales, pellucidly punctate. 

 Flowers in simple or compound erect racemes. Calyx-tube quadran- 

 gular, limb almost square, teeth eventually spreading.' Stamens ex- 

 serted. Disk with 4 shallow obcordate lobes. Petals minute, oblong- 

 lanceolate, undulate, pale yellow. Fruit pedicellate, about 10 lines 

 long and 9 lines broad, base obtuse, tipped at the apex with the persis- 

 tent base of the style, brownish yellow. 



Lower Guinea. Angola, Dr. Welwitsch! Growing at the height of 2000- 

 3000 ft. 



A smaller tree from more exposed parts has obovate leaves 2£-3 in. long. 



28. C. rubiginosum, Welm. mss. Tree, 20-25 ft. ; young branches 

 and petioles dark purple. Leaves opposite, broadly lanceolate, 4—6 in. 

 long by 1 J-2J in. broad, with an obtuse or cordate often unequal base, 

 dark green and shining above, ferruginous beneath ; petioles slender, f in. 

 long, covered with small white distant scales above and larger densely
