2602 LEAFLETS OF PHILIPPINE BOTANY [VoL. VII, Arr. 114 
alternatingly scattered along the wiry branchlets, curvingly 
conduplicate on the upper dull green surface, paler green 
beneath, glabrous, entire margins minutely involute, apex 
obtuse or short and bluntly acute, base rounded or broadly 
obtuse, elliptic or ovately oblong, lamina 7.5 cm long, 3.5 
em across the widest portion, nearly black on the upper 
side when dry, dull brown onthe nether side; midrib bold 
beneath, minutely grooved along the upper side; the 6 to 9 
pairs of lateral nerves faint, ascending, their tips strongly 
curved but not united, reticulations none; petiole glabrous 
when old, 1 cm long, deeply channelled along the upper 
side. Inflorescence terminal or upon leafless lateral branch- 
lets, suberect; rachis densely badius pubescent, 1 to 3 dm 
long, angular in the dry state, more or less wavy, branch- 
ed all along from near the base; branchlets alternating, less 
than 3 cm long, divaricate or ascending, similarly pubes- 
cent, subtended by bract vestiges, occasionally short rebranched 
rom above the middle; flowers odorless, scattered toward 
the distal end of the branches; pedicel 3 mm long, castaneus 
hirsute, subtended by similarly pubescent bracteoles; buds 
subglobose; calyx bowl shaped, imbricate, 8 mm high; sepals 
5, nearly free, elliptic, castaneus pubescent on the outside 
and ciliate along the edges, rather thick in the middle por- 
tion toward the base, glabrous on the inner side; petals of 
an equal number, white, the basal one third falsely united 
into a tube, totalling 7 mm long, only 2.5 mm wide, nar- 
rowly oblong, tapering toward the base, the upper one third 
usnally expanded into a left glabrous divaricately spreading 
wing or occasionally forked or irregular on both halves, both 
sides but especially the lower pulverulent, the basal portion 
glabrous as are the rotately spreading wings; stamens 5, in- 
cluded, alternating with the segments and partly adnate to
