 it from /. fragrans Bojer. In habit it recalls I. nsarifolid R. & S., 

 which it also somewhat resembles in the form of the flower ; but it 

 is distinguished by the shape of its leaves and larger oblong bracts.

" Springs in pretty tufts." Branches 6-16 cm. long, the 

 thickest 2*5 mm. in diameter at the base. Leaves not exceeding 

 2*5 cm. in length by 1*5 in breadth, with a petiole barely '5 cm. 

 long, generally smaller. Flower-pedicels •5-1*5 cm. Sepals 

 lanceolate to bluntly ovate, 5-7 mm. long by 2*5-3 mm. broad. 

 Corolla infundibuliform, 4*5 cm. long, with a tube 2 cm. long by 

 3 mm. in diameter at the base ; spread of mouth in dried specimen 

 4*5 cm. 



Differs, and is at once distinguished from the species, by the 

 sessile or almost sessile inflorescences.

The specimens consist of the upper portions (about 30 cm. long) 

 of several laxly leaved shoots with internodes hollow, flattened and 

 grooved, and about 2 mm. broad, bearing, Ukc tiie peduncles, 

 pedicels, leaf stalks, and prominent nervation on the under sur- 

 face of the leaf, a dense faintly ferruginous toraentum of short 

 stellate hairs. Leaves 2*5-3 cm. long or less, and nearly as broad, 

 the upper surface rugulose by the depression of the veins and 

 veinlets, petioles -5-1 cm. long. Peduncles 1-2*5 cm. long ; 

 bracteoles minute, ovate, caducous, barely 3 mm. long, pedicels
