The long and very flexible shoots, 55-4 it. or more, spring irom 

 a woody rhizome ; the shoots, according to a note by Welwitsch, 

 are prostrate, "parum volubiles, necdum scandens quum legi," 

 though in the British Museum specimens they look as if they had 

 been trying to climb. The leaves vary somewhat in shape, being 

 ovately cordate in the upper part of the shoot, bat more oblong or 

 even oval in the lower parts ; in size they vary from 1^ to 3 in. in 

 length, and from ^ to 2^ in. in breadth ; the petioles vary from 

 £ to If in. long. The bracts are broad, and situated a little below 

 the calyx, the outermost sepals of which they resemble ; they are 

 from ^ to f in. in length, and are about ^ in. broad ; like the sepals, 

 they are fringed with stiffish yellow hairs ; the outermost sepal is 

 7 lines long by 4£ broad at the base; the next higher is slightly 

 narrower, ovate-acuminate ; the third lanceolate, and the other two 

 linear-subulate. The corolla has a purple-red tube, and a light 

 upper part ; it is 19 lines long. The stamens, which are of three 

 lengths, as in I. porrecta, are inserted in the tube 4 lines from its 

 base ; the filament of one of the two longer ones measured 4 lines, 

 the anthers are f line long. 



This species is very near the Abyssinian I. fulviraulis Boiss. 

 {Amseia ftdvicauUs Hochst.), which, however, besides having the 

 whole plant densely pilose, has a much smaller flower, and more 

 generally oblong leaves.
