COLUMELLA PTERITA sp. nov. 
Scandens, glabra, ramulis ramulisque herbaceis alato-hexa- 
gonis; foliis pedatim 7-foliolatis, 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,

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

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

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
