A small low-growing plant with a stout woody caudex, from 

 which spring a number of slender, very flexuose shoots, 5-9 cm. 

 long, and 1-5-2 mm. thick, which, like the petioles, are densely 

 covered with short stiffish flexuosely-spreading yellowish-brown 

 hairs. Leaf-stalks 1-5-2-2 cm. long by about 1 mm. broad, leaves 

 2-5-3-5 cm. long, and generally as broad, densely covered on both 

 surfaces, especially on the veins, with short stiffish appressed hairs 

 springing from a small indurated base. Flower-buds bluntly coni- 

 cal. Pedicels 4 mm. long or less, bracteoles -5 cm. long, hairy on 

 the back like the leaves and the sepals, sepals 1 cm. long, the 

 outer 4 mm., the inner less than 1 mm. broad. Corolla (withered) 

 2-2 cm. long, tube barely 2 mm. broad above the base. 



Near I. asperifoHa Hall, f., but distinguished by having leaves 



about as broad as long, and by the elliptical not ovate outer sepals.
