NOTES ON AFRICAN CONVOLVULACEiE 17 



calyce paullo remotis velut pedunculis hispidulis ; sepalis ovato- 

 lanceolatis, acutis, dorso plus minus hispidulis; tribus interioribus, 

 duos externos paullo excedentibus ; corolla infundibuliforme, pur- 

 purea, calycem plus duplo excedente, areis mesopetalis valde limi- 

 tatis, 3-5-nerviis. 



Described from a shoot cut off at the base, and 80 cm. long and 

 2 mm. greatest diameter. Leaves reaching 5 cm. long by 3-7 cm. 

 broad, becoming smaller as we ascend the shoot ; petioles to 1 cm. 

 long; midrib and pinnae subpromiuent on the under leaf-surface, 

 pinn^ 5-6 on each side, spreadiug-ascendent, the two lower arising 

 just above the leaf-base ; the reticulate connecting veins conspicuous 

 on both surfaces in the dried leaf, but especially on the under. 

 Peduncles -5-3 cm. long, jointed at the base ; bracteoles 5-6 mm. 

 long, less than 1 mm. broad, 2-4 mm. below the calyx. Sepals 

 12-14 mm. long by about 4 mm. broad. Corolla 3-5 cm. long, 

 tube 7 mm. in diameter (when dried and pressed), spreading to 

 about 3-5 cm. at the mouth. 



Near /. oblongata E. Meyer, but distinguished by its cordate- 

 ovate leaves and jointed peduncles.

I. sublucens, sp. nov. Suffrutex ramosus, cauhbus ramisque 

 ut tota planta sublucenter et albide sericeo-pubescentibus, lignosis, 

 flexuosis, siccis angulatis compressis, non solidis ; foliis oblongo vel 

 elliptico-ovatis, apice rotundatis, basi subcordatis, petiolos triplo 

 excedentibus, in facie superiore sparsius, in facie inferiore margini- 

 busque densius, et in foUis junioribus lucenter, albide serfceo- 

 pubesceutibus ; pedunculis uniflods, quam folia duplo brevioribus ; 

 bracteolis ad_ calycem subapproximatis, lineari-spatulatis ; sepalis 

 anguste ovatis, exterioribus latioribus acutis, interioribus acumi- 

 natis; corolla purpurea quam calyx triplo longiore, ut apparet 

 infundibuliforme, areis mesopetalis bene definitis, dorso albide- 

 pilosis. 



The specimen consists of a branched shoot nearly 70 cm. long, 

 which, especially in the younger parts, bears a short white some- 

 what shining pubescence ; the angular internodes reach 2 mm. in 

 diameter. Leaves 4-5-6-5 cm. long, 2-3*5 cm. or rarely 4 cm. 

 broad ; petioles 2 cm. or less ; midrib broad, prominent on the 

 back of the blade, lateral veins pinnate, subprominent, ascending, 

 crowded at the base of the leaf ; the back and margin in the young 

 still plicate leaves bears a dense shining silky pubescence, which 

 on the back becomes less bright and dense in the older leaves. 

 Peduncles 2-5-3 cm. long ; bracteoles about 1-5 cm. long, barely 

 reaching 3 mm. in breadth below the apex. Sepals l'5-l-7 cm. 

 long, 4 mm. or less in breadth, the inner narrower and sHghtly 

 larger than the outer. Corolla much withered and eaten, 4-5 cm. long. 



A very distinct species, perhaps nearest I. oblongata E. Mey., 

 but differing in its silky whitish covering, larger leaves, longer 

 bracteoles, &c.
