of the buds slightly enlarged, the enlarged parts of the sepals, 

 above the insertion of the stamens narrowly oblong, about 3.5 

 mm long. Anthers about 2.5 mm long. Ovary glabrous. Pedi- 

 cels 2 to 3 mm long, in pairs, slightly united at the base. 



Luzon, Province of Sorsogon, Mount Kililibong, Bur. Sci. 23S20 (type), 

 2S632 Ramos, August, 1915, on forested slopes near the summit of the 

 mountain. 



This is in the group with Helicia philippinensis Meissn. and H. cuming- 

 iana Meissn., but has rather smaller leaves with fewer lateral nerves 

 than either of the above species. It is, however, manifestly very closely 

 allied to both.

 NARAVELIA PHILIPPINENSIS sp. nov. 



Scendens, inflorescentiis sepalisque prominente ferrugineo- 

 pubescentibus exceptis glabra; ramulis brunneis vel pallidis, 

 cylindraceis, longitudinaliter striatis; foliis 3-foliolatis, foliolis 

 integris, ovatis ad oblongo-ovatis, usque ad 9 cm longis, charta- 

 ceis, glabris, nitidis, apice obtusis vel obscure apiculatis, basi 

 rotundatis ad acutis, 5-pli- vel obscure 7-plinerviis, nervis exte- 

 rioribus rectis, adscendentibus, reticulis laxis; inflorescentiis 

 axillaribus, usque ad 20 cm longis, paucifloris; floribus 4-meris, 

 sepalis oblongis, acutis, recurvatis, circiter 9 mm longis, utrinque 

 ferrugineo-pubescentibus. 



A scandent plant, the branches terete, up to 4 mm in diameter, 

 pale or brown when dry, longitudinally striate, the internodes 

 up to 20 cm in length. Leaves 3-foliolate, glabrous, their pe- 

 tioles about 10 cm long, often twining about branches and other 

 objects to support the plant; leaflets glabrous, shining, olivace- 

 ous, chartaceous, oblong to ovate-oblong, 6 to 9 cm long, 3.5 to 

 5 cm wide, entire, base rounded to somewhat acute, distinctly 

 5-plinerved or indistinctly 7-plinerved, apex obtuse or obscurely 

 apiculate; nerves leaving the midrib within the lower 1 cm, the 

 outer, basal ones straight, prominent, ascending, the reticula- 

 tions lax; petiolules 3 to 4 cm long, like the petioles sometimes 

 twining. Panicles axillary, up to 20 cm long, rather narrow, 

 few flowered, the lower primary branches scarcely exceeding 3 

 cm in length, the upper shorter, all parts rather prominently 

 ferruginous-pubescent with short hairs. Flowers yellowish, 4- 

 merous, their pedicels 1 to 1.5 cm long. Sepals oblong, acute, 

 recurved, ferruginous-pubescent or both surfaces, about 9 mm 

 long and 4 mm wide. Petals none. Stamens indefinite, slender, 

 slightly cinerous-puberulent, 6 to 7 mm long.
