NOTES ON AFRICAN CONVOLVULACEiE 15 



accounted for, which, though doubtless inseparable from Dr. 

 Hauler's aggregate, must, I think, in the more usual acceptance 

 of the term, be regarded as distinct species ; their descriptions 

 follow. 



I. sarmentacea, sp. nov. Sufirutex caulibus tenuibus lignosis 

 e basi crassa lignosa brunnea eforuie prostratis, fiexuosis, teretibus, 

 tortulis, ut sunt petioli, nervi in fohorum dorso prominentes, pedun- 

 culi, bracteolc^, et sepala tenuiter hispiduhs ; foliis oblongo-ovatis, 

 obtusis, basi breviter subcordatis vel retusis, facie superiore saturate 

 viride, parciter appresse pilosa, facie inferiore veuulosa, petiolis 

 brevibus ; pedunculis unifloris quam folia ^-i-brevioribus, bracteolis 

 parvis, anguste lanceolatis acuminatis, a calyce paullo remotis • 

 sepalis binis exterioribus ovatis basi vix ampliatis acutis, interiori- 

 bus angustioribus ; corolla tubiiloso-infundibulare, calycem duplo 

 excedente, ut apparet purpurea. 



Shoots 20-40 cm. long, a little over 1 mm. in maximum breadth. 

 Leaves 2-5-5-5 cm. long by 1-8-2 cm. broad, the under surface a 

 much lighter green than the upper, and chased with the darker and 

 decreasmgly prominent midrib, ascending lateral veins, and often 

 ladder-like cross unions. Petioles 5-7 mm. long. Peduncles (in- 

 cluding pedicel) of open flowers 1-2-1-5 cm. long, bracteoles 

 7-8 mm. long by 1-5-1 -75 mm. broad. Outer sepals 12 to barely 

 15 mm. long by 5-6 mm. broad, the two innermost (1-5 cm. long) 

 linear, tapering from a base scarcely exceeding 2 mm. broad, the 

 intermediate lanceolate, 3-5 mm. long. Corolla nearly 8-5' cm. 

 long, tube a little over 2 cm. long, and 5-6 mm. in diameter about 

 the middle, spread of mouth of corolla 2-8 cm. 



The vegetative characters closely resemble, from the description 

 {I.e. p. 49), those of Hallier's /. crassipes var. r/randifolia, but the 

 peduncles are shorter (2-7 cm. in the variety), the small bracteoles 

 narrow-lanceolate, not linear, and the sepals only about half as 

 broad, those of var. grandifolia being described as "1 cm. lata" ; 

 the corolla is also larger. The new species has the broad ovate 

 outer sepals of /. crassipes, but in the form of leaf approaches 

 I./u/vicaiilis ; the latter, however, differs in the density and colour 

 of its tomentum, several-flowered heads, &c.

I. bellecomans, sp. nov. Suffrutex cinereo-pilosa, cauhbus 

 robustis sublaxiter foliatis, ramosis, siccis stepe compressis, baud 

 sohdis, ramis s«pe strictis, patentibus ; foliis parvis, breviter petio- 

 latis ovatis obtusis basi interdum truncatis, utrinque densissime 

 cmereo-pilosis ; pedunculis unifloris, folia excedentibus ; bracteolis 

 a calyce remotis, ovatis ; sepalis externis maguis ovatis ad folia 

 simihbus sed acutis, internis admodum angustioribus e basi lanceo- 

 lata acuminatis ; corolla (marcida) ut apparet roseo-purpurea in- 

 fundibuliforme et calycem plus duplo excedente, in areis mesopetalis 

 pile sola. 



The longest shoot (broken at the base) in the specimens measures 

 55 cm. m length, and 3 mm. in breadth ; the shoots, like the branches, 

 are somewhat densely covered with soft rather short whitish hairs'
