This species was originally identified as Urophyllum luc- 
banense Elm., but it is not closely allied to that species. It is 
easily distinguished by its solitary pedicellate flowers, the ped- 
icels being supplied with a whorl of four narrow, elongated, free 
bracteoles.

WILLIAMSIA PANAYENSIS sp. nov. 
Frutex erectus plus minusve molliter cinereo-villosis ; foliis 
membranaceis ad chartaceis, oblongis, usque ad 24 cm longis, 
perspicue acuminatis, supra glabris vel subglabris, subtus ad 
costa nervisque molliter villosis, nervis utrinque id ad 20, per- 
spicuis ; floribus solitariis, sessilibus, $ fasciculatis, bracteoli’s 
involucrantibus dense villosis, exterioribus 4-lobatis, 3 ad 4 mm 
diametro, interioribus profunde 4-lobatis, vel segmentis liberis, 
oblongo-ovatis, 3.5 ad 5 mm longis; calycis dense villosis, 4- 
lobatis ; corollae lobis G vel 7, oblongis, 4 ad 4.5 mm longis. 
An erect shrub, the branches, flowers, petioles, and leaves on 
the midrib and nerves beneath softly cinereous-villous. Leaves 
membranaceous to chartaceous, oblong, 16 to 24 cm long, 6 to 9 
cm wide, grayish-olivaceous when dry, the upper surface ulti- 
mately glabrous, the lower surface softly villous on the midrib 
and nerves, base acute to obtuse, apex rather prominently acu- 
minate; lateral nerves 16 to 20 on each side of the midrib, 
prominent on the lower surface, curved, anastomosing, the re- 
ticulations distinct; petioles densely villous, 1.5 to 2.5 cm long; 
stipules narrowly oblong, densely villous, about 2 cm long. 
Flowers polygamous, the perfect ones usually solitary, sessile or 
subsessile, the staminate ones in few-flowered fascicles. Perfect 
flowers subtended by two series of densely villous bracts, the 
outer series forming a deeply lobed cup, 3 to 4 mm in diameter, 
the inner series larger, cleft nearly or quite to the base into four, 
oblong-ovate, acuminate lobes, 3.5 to 5 mm long. Calyx densely 
villous, the lobes 4, ovate to oblong-ovate, somewhat acuminate, 
4 mm long. Corolla-tube 3 mm long, the lobes 6 or 7, white, 
oblong, acuminate, 4 to 4.5 mm long, densely villous externally, 
the throat densely bearded, the stamens 6 or 7. Staminate 
flowers smaller than the perfect ones but otherwise similar. 
Fruits globose, about 1 cm in diameter, rather densely villous.
