 nerved underneath, reticulately veined, of rather a 

 glossy green on the upper side and paler underneath, 

 hairy on both sides, the hairs underneath in little tufts ;

 and fringed with tufts of short hairs, and some longer 

 ones intermixed : the leaves on the flower-stems sessile, 

 connected at the base, more prominently three-nerved, 

 and the points less sharp. Flower-stems axillary and 

 terminal, also clothed with tufts of short hairs, and 

 some long ones intermixed. Peduncles clothed with 

 tufts of short woolly hairs, and some longer ones inter- 

 mixed. Calyx of 5 sepals, the 3 outer ones broadly 

 cordate, with long taper points, striated with nume-
