xin,c,2 Merrill: New Species of Bornean Plomts 95 



A glabrous scandent plant, the branches slender, pale or brown- 

 ish when dry, obscurely striate. Leaves ovate to oblong, entire, 

 pale-olivaceous, shining, of about the same color on both surfaces, 

 chartaceous, 4 to 6.5 cm long, 3 to 4.5 cm wide, base broadly 

 rounded and distinctly cordate, beneath with a pair of distinct 

 auricle-like glands, narrowed upward, the apex obtuse to obtusely 

 acuminate and usually minutely apiculate; lateral nerves pin- 

 nately arranged, 4 or 5 on each side of the midrib, curved, 

 anastomosing, slender but distinct, the reticulations lax ; petioles 

 1 cm long or less. Inflorescences 4 to 7 cm in length, few- to 

 many-flowered, dichotomous, peduncled, the tendrils from the 

 apices of the peduncles between the two primary branches. 

 Flowers yellow, about 1 cm long, their pedicels slender, 1 to 2 

 cm in length, the bracteoles minute, the perianth narrowly 

 oblong-ovoid, acute at both ends, the sepals 4, oblong-ovate, 

 obtuse, about 1.5 mm long, the petals linear-oblong, 1.5 mm long, 

 thin, inserted at the apex of the perianth-tube. Stamens 4; 

 anthers narrowly oblong, 4 to 4.5 mm long. Fruits red when 

 mature, oblong-ovoid, narrowed at both ends, base and apex 

 acute, 7 to 9 cm long, apparently pendulous, 3-valved, apparently 

 terete, the valves thickly coriaceous, hard and stiff when dry, 

 reddish-brown, smooth and shining. Seeds ellipsoid, compressed, 

 prominently and densely subfoveolate, 8 to 9 mm long.

This species much resembles the Javan Adenia cordifolia (Blume) Engl. 

 as figured and described by Blume, Rumphia, 1 (1835) 167, t. 49, from 

 which it is at once distinguished by its 4-merous, not 5-merous flowers. 



ADENIA CLEMENTIS sp. nov. § Microblepharis. 



Frutex scandens, glaber; foliis chartaceis, oblongis, usque ad 

 10 cm longis, subolivaceis, nitidis, utrinque subaequaliter an- 

 gustatis, integris, tenuiter acuminatis, basi acutis, perspicue 

 auriculato-glandulosis, nervis utrinque 4, distinctis; inflorescen- 

 tiis axillaribus, cymosis, pedunculatis, paucifloris, 4 ad 6 cm 

 longis; floribus 5-meris, anguste oblongo-ovoideis, 8 ad 9 mm 

 longis, utrinque subacutis; fructibus ovoideo-ellipsoideis, tereti- 

 bus, circiter 5 cm longis, apice subrotundatis, basi subacutis vel 

 subrotundatis. 



A scandent glabrous shrub, the branches terete, pale or brown- 

 ish, slightly striate when dry. Leaves oblong, chartaceous, 

 subolivaceous to somewhat pale when dry, of about the same 

 color on both surfaces or somewhat paler beneath, shining, 7 

 to 10 cm long, 2.5 to 6 cm wide, subequally narrowed to the
