Stem shrubby, much branched, growing to the height 

 of 2 or 3 feet if supported, erect or flexuose, seldom 

 growing in the manner represented in the Botanical 

 Magazine; branches more or less flexuose, densely 

 clothed with a close pressed white tomentum, and a few 

 spreading white hairs intermixed. Leaves opposite, ses- 

 sile, very much attenuated towards the base, with blunt 

 points, greenish and hairy on the upper side, and 

 clothed with a thin tomentum underneath : lower ones 

 short, roundly ovate, and green on both sides : upper 

 ones ovately lanceolate or spathulate, slightly 3-nerved, 

 clothed with a thin white tomentum on the lower side, 

 and with little fascicles of hairs at the margins, which 

 gives them an appearance of being crenulate: young 

 leaves white on both sides. Flowering branches a little 

 panicled, leafy at the base, clothed with spreading slen- 

 der hairs, but not woolly as on the other branches. Pe- 

 duncles and pedicles slender and hairy. Calyx of only 

 3 sepals, which are nearly equal, lanceolate, taper point- 

 ed, and clothed with long spreading loose white hairs. 

 Petals 6, spreading, nearly or sometimes quite distinct
