22 cm long, 4 to 6.5 cm wide, the apex abruptly and sharply 
acuminate, the base acute; lateral nerves about 18 on each side 
of the midrib, prominent; petioles 1.5 to 2 cm long; stipules 
narrowly oblong, about 4 cm long, 5 mm wide, sligthly pilose, 
obtuse, the nodes under the deciduous stipules distinctly bearded. 
Flowers axillary, fascicled, apparently shortly pedicelled (not 
seen). Fruit pale-yellow when fresh, narrowly ovoid, nearly 
glabrous, about 12 mm long, 7 mm in diameter, about 7-celled, 
the persistent basal involucre of 4 lobes united for about 3 mm, 
two lobes ovate, acute, 8 mm long, 7 mm wide, alternating with 
two oblong acute lobes about 4 mm long and 3 mm wide, the 
involucre itself glabrous or nearly so externally, inside very 
densely villous, seated on a thickened villous disk and subtended 
by a lanceolate, acuminate, villous bracteole about 3.5 mm long ; 
persistent calyx-teeth 4, broadly ovate, rounded, 2 mm long, 
externally sparingly villous, internally densely so.

Quite distinct from Williamsia sablanensis (Elm.) Merr., the type of 
the genus, in its straight, not at all falcate, more numerously nerved leaves, 
and its much longer stipules. 
WILLIAMSIA GLABRA sp. nov. 
Frutex 2 m altus, glaber vel subglaber; foliis lanceolatis, ten- 
uiter acuminatis, rectis, chartaceis vel subcoriaceis, usque ad 
14 cm longis, in siccitate pallidis, nitidis, nervis utrinque cir-

A shrub about 2 m high, nearly glabrous. Branches terete, 
glabrous, pale greenish-yellow, slender. Leaves opposite, lan- 
ceolate, chartaceous to subcoriaceous, 11 to 14 cm long, 2.5 to 
4 cm wide, entire, the apex long and slenderly acuminate, the 
base acute, glabrous, when dry pale and shining; lateral nerves 
about 7 on each side of the midrib, prominent, curved-ascend- 
ing, anastomosing; petioles 1 to 1.5 cm long; stipules linear to 
linear-lanceolate, 10 to 12 mm long. Flowers nearly white, 
axillary, solitary or somewhat fascicled, subsessile or on a very 
short stout pedicel, each flower subtended by 3, cup-shaped, 
superposed involucres, the lowermost one 1.5 mm in diameter, 
about 1 mm high, the second a little larger, the third about 2 
mm in diameter and about as long, distinctly 4-toothed, the 
others irregularly toothed. Calyx somewhat swollen in the mid- 
dle, the base acute, 3 mm in diameter, 5 to 6 mm long, the limb 
irregularly 4-toothed, slightly villous. Petals 4, valvate, thickly
