DESCRIPTION OF ALL SPECIMENS EXAMINED: 
Shrub; 45-75 cm. tall; older branches 4-8 mm. 
in diameter, with the bark gray, roughened by 
longitudinal furrows, and also by the long 
persisting stipules, finally the bark whitish; 
leaf scars 1.2-1. 5 mm, wide, lunate-elliptic, 
pale, corky; bundle scar 1, large, transverse; 
twigs leafy for 1-18 cm., bearing 7-29 leaves, 
these spreading and eventually reflexing, 
rather crowded; upper leafy stems 1-2.3 mm. 
in diameter, greenish, the surface white ap- 
pressed puberulent but largely concealed by 
the persistent, rigid, imbricate stipules; nodes 
1-6, commonly 1.5 mm. apart; stipules 2.5-4 
mm. long, broadly oblique ovate, the base 
cordate, the midrib heavy, raised, it and the 
central strip densely white appressed puberu- 
lent, the wide sides membranous, brown, 
glabrous, the margins white ciliate; petioles 
3-11 mm. long, white puberulent; blades 2.6 
cm. long, 6-19 mm. wide, coriaceous, lance- 
olate, the margin perceptibly remotely low 
crenulate, above dark green, sublucid, white 
puberulent on the midrib and remotely so on 
the smaller veins, below yellowish green and 
similarly puberulent, strongly reticulate 
veined; the secondary veins 5-7 on a side, 
sharply ascending and inarched connecting 
well in from the margin; flowers fragrant, 
single, axillary; peduncle 2-8 mm. long, ap- 
pressed white puberulent; pedicels 2-4 mm. 
long, appressed white puberulent; peduncu- 
lar bracts 2. 3-3. 2 mm. long, puberulent on 
midrib and margin like the stipules; sepals
