 (Aug. 1895). I. ficifolia Lindl. var. laxlfiora subvar. parvijlora 

 Hall. f. in Engl. Jahrb. xxviii. 35 (1899). 



East Tropical Africa. " Higher slopes of Mt. Kilimanjaro up 

 to 10,000 ft. above Morang," Eev. W. E. Taylor, 1888, 



I cannot follow Hallier in uniting this species with the South 

 African LJicifolia Lindl. It is, I think, as near /. pilosa Sweet 

 (= /. dichroa Choisy), and distinguished from both by the ovate-cor- 

 date leaves, with a flower smaller than that of I.Jicifolia, and larger 

 than that of I. pilosa. 



I. Eenii, sp. nov. Suffrutex caulibus volubilibus albide- vel, in 

 partibus junioribus, flavescente-pilosis ; foliis breviter petiolatis, 

 palmato-3-partitis, segmentis lanceolatis vel anguste ellipticis 

 acutis, lateralibus cum lobo basale instructis, pagina superiore, 

 margine, et venis primariis secundisque paginae inferioris cum 

 pilis flavescentibus indis, pagina inferiore venis exceptis breviter 

 albo-tomentosa ; petiolis pedunculisque ut in caulibus pilosis ; 

 pedunculis petiolos excedentibus 1- vel 2-floris ; bracteolis ad 

 flores approximatis, ad sepala similibus ; sepalis lanceolatis, acumi- 

 natis, dorso pilosis et margine ciliatis, tribus interioribus quam 

 exteriora angustioribus ; corolla infundibuliforme calycem duplo su- 

 perante, areis mesopetalis trinerviis ; genitalibus inchisis ; fructu . . . 



The specimen consists of about 35 cm. of the upper part of two 

 intertwining shoots which reach 1-5 mm. in thickness, and have a 

 covering of soft whitish or, especially in the younger parts, pale 

 yellowish hairs. The median leaf-segment reaches 2-5 cm. long by 

 8-10 mm. broad, the lateral are slightly smaller, and bear on 

 the outside at the base a blunt roundish lobe 5-8 mm. long ; 

 petioles barely reaching 2 cm. long. Peduncles 2-5 cm. long, 

 bracteoles immediately beneath tlie flower and resembling the 

 sepals, but slightly smaller, 8-9 mm. long by 2 mm. broad. Sepals 

 11 mm. long, the outer 3 mm., the innermost 1*5 mm. broad. 

 Corolla 2-5 cm. long, spread at mouth about 2*5 cm. ; diameter of 

 tube 6 mm., length about 1 cm. Filaments 6*5-9 mm. long. 

 Ovary conical, style 6 mm. long, stigmas subrotund. 



Apparently near I. Marpiusiana Schinz, which I have not seen, 

 but which has much smaller bracteoles and flowers, longer-stalked 

 leaves, &c.
