COLUMELLA PTERITA sp. nov. 



Scandens, glabra, ramulis ramulisque herbaceis alato-hexa- 

 gonis; foliis pedatim 7-folioIatis, petiolulo medio unifoliolato, 

 lateralibus 3-foliolatis, foliolis membranaceis, grosse apiculato- 

 serratis, longe tenuiter acuminatis, usque ad 9 cm longis ; semin- 

 ibus 4, faceibus ventralibus 2. 



Scandent, glabrous in all parts, the branches somewhat fleshy 

 when fresh, 6-angled, narrowly winged down each angle, the 

 wings about 1 mm wide. Tendrils slender, forked, up to 30 cm 

 in length. Leaves pedately 7-foliolate, their petioles 3 to 6 cm 

 long; leaflets membranaceous, glabrous, ovate-lanceolate, the 

 base acute, the apex long and slenderly acuminate, the margins 

 coarsely serrate, the teeth apiculate, 7 to 9 cm long, 2 to 3.5 cm 

 wide; petiolule of the middle leaflet 1 to 1.5 cm long, the common 

 ones of the three lateral leaflets somewhat shorter, the petiolules 

 proper of the lateral leaflets 5 mm long or less. Cymes rather 

 lax, leaf -opposed or subterminal, about 12 cm long including the 

 peduncle. Flowers greenish-white, 4-merous. Calyx truncate. 

 Petals 4, 2 mm long, somewhat cucullate at the apex, obtuse, 

 not at all corniculate. Fruit subglobose, about 1 cm in diameter,

Similar to and manifestly allied to Cayratia japonica (Willd.) Gagnep., 

 but distinguished from this and allied forms by its 7-foliolate leaves. 



COLUMELLA SIMPLICIFOLIA sp. nov. 



Frutex scandens, glaber, ramis ramulisque teretibus; foliis 

 1-foliolatis, petiolo 3 ad 4 cm longo, foliolis coriaceis, ovatis ad 

 late ovato-ellipticis, usque ad 10 cm longis, acuminatis, basi late 

 rotundatis, margine distanter crenulato-serrulatis, nervis utrin- 

 que circiter 7, tenuibus, indistinctis vel subobsoletis, reticulis 

 obsoletis; inflorescentiis axillaribus, 5 ad 7 cm longis, floribus 

 ut videtur in ramulis ultimis umbellatim dispositis; fructibus 

 carnosis, ellipsoideis ad obovoideis. 



A scandent glabrous vine, the branches and branchlets terete, 

 glabrous, brownish when dry. Leaves reduced to a single leaflet, 

 the petioles 3 to 4 cm long, the leaflet coriaceous, very brittle
