 This is a very distinct species, the stem and branches 

 being decidedly woody and of hard texture ; the leaves are 

 from 6 to 10 lines long, 1-1 ^ line broad, densely covered 

 with short viscid pubescence, which is incanescently tomen- 

 tous beneath. The peduncles are 6 lines long, and become 

 deflexed on the fall of the corolla : the calyx is 3-4 ti nes 

 long, cleft into 5 unequal linear obtuse teeth; the corolla 

 is about 9 lines long, 6 lines broad across the mouth, the 

 tube being contracted below, where it is yellowish, above it 

 is funnel-shaped and ventricose, of a deep rose colour, a nd 

 veined, the border being divided into 5 ovate rounded lobes ; 

 the stamens are unequal, 4 of the anthers approximate i n 

 didynamous pairs, while the fifth is intermediate between the 

 longer pair, and is much shorter : the ovarium is obovate
