HEDYOTIS BAMBUSETORUM sp. nov. 
Suffruticosa, ramosa, usque ad 1 m alta, inflorescentiis leviter 
hirsutis exceptis glabra, caulis teretibus, laevis, 4 mm diametro, 
ramulis teretibus vel leviter compressis vel sulcatis; foliis 
oblongo-ovatis ad ovato-lanceolatis, usque ad 17 cm longis, 
chartaceis, in siccitate olivaceis, nitidis, fragilis, tenuiter acute 
acuminatis, basi acutis ad subrotundatis, nervis utrinque 6 vel 
7, curvato-adscendentibus, utrinque elevatis; stipulis latis, pecti- 
natis, laciniae circiter 13, 7 ad 8 mm longae, glabrae, glanduli- 
ferae; inflorescentiis axillaribus, sessilibus, globosis, 1 ad 1.5 
cm diametro; floribus numerosis, confertis, 5 mm longis, calycis 
lobis 4, lanceolatis, obscure hirsutis, 2 mm longis. 
A suffrutescent, erect, branched plant up to 1 m high, glabrous 
except the very slightly hirsute inflorescences, the stems smooth, 
terete, subolivaceous, 4 mm in diameter, the branchlets terete 
or slightly compressed or sulcate. Leaves oblong-ovate to ovate- 
lanceolate, chartaceous, 9 to 17 cm long, 3 to 5 cm wide, when 
dry olivaceous, shining, fragile, smooth, the apex slenderly and 
acutely acuminate, the base acute to somewhat rounded or even 
decurrent; lateral nerves 6 or 7 on each side of the midrib, 
curved-ascending, projecting on both surfaces, slender but 
distinct, obscurely anastomosing, the reticulations lax, not prom- 
inent; petioles of the larger leaves 1 to 1.5 cm long; stipules 
broadly triangular, glabrous, about 8 mm wide, the body about 
5 mm long, pectinate, the segments about 13, linear, the median 
ones longer, 7 to 8 mm long, the outer ones shorter, 3 to 4 mm 
long, all gland-tipped. Inflorescences axillary, globose, sessile, 
dense, 1 to 1.5 cm in diameter. Flowers white, numerous, 
crowded, the bracteoles lanceolate, acuminate, 4 to 6 mm long, 
slightly hirsute, the pedicels 1 mm long or less. Flowers about 
5 mm long, 4-merous. Calyx tube glabrous, 1.5 mm long, the 
lobes lanceolate, about 2 mm long, glabrous or slightly hirsute. 
Corolla tube slender, glabrous, 8 mm long, the throat and lobes 
slightly bearded inside, the lobes oblong-lanceolate, 1.5 mm long. 
Style glabrous, 5 mm long. 
PALAWAN, Taytay, Merrill 9214, April, 1913. Along trails in 
bamboo thickets at low altitudes. 
A species apparently most closely allied to the Bornean Hed- 
yotis platyphylla Merr., but differing in its branches, its terete 
stems, more numerous segments of its stipules, shorter petioles, 
and in its nerves not being impressed on the upper surface.
