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, conf ertis, 5 mm longis, calycis 

 lobis 4, lanceolatis, obscure hirsutis, 2 mm longis. 



A suff rutescent, 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, 3 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 921^, 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.
