Scandens, fruticosa, glabra; rami trianguläres, juxta angulos utrinque sulco levi (Linea 

 impressa) notati, lateribus planis vel in costam obtusam productis (rami inde interdum plus 

 minus „sexcostati", uti a Triana & Planch. dicuntur); corpus lignosum compositum e cen- 

 trali majore et periphericis 3 minoribus angulis subjectis; folia ternata; foliola breviter elliptica, 

 apice basique acutiuscula, supra medium remote crenato- vel subrepando-dentata, bre- 

 vissime petiolata, membranacea, sicca vix fuscesceutia, supra opaca (epidermidis cellulis in 

 papillas late conicas evolutis), subtus nitidula et in axillis nervorum seriebus pilorum ornata, 

 insuper supra subtusque glandulis microscopicis breviter stipitatis curvatis adspersa, reti 

 utriculorum laticiferorum subpellucido interrupto (ad paginam inferiorem) instructa, epider- 

 mide non mucigera; petiolus alatus; thyrsi abbreviati, in axillis foliorum ramorum juniorum 

 in glomerulos sat densos aggregati; alabastra hirtella; flores minores, germine hirsuto-tomen- 

 toso; fructus sectionis ex obovato clavatus, breviter stipitatus, apice apiculatus, ex hirsuto 

 glabrescens; semen (immaturum) ellipsoideum , arillo dorso profundius quam ventre fisso ad 

 duas tertias obtectum. 



Rami thyrsigeri diametro 2,5 mm. Folia 12 — 15 cm longa, fere totidem lata; foliola 

 terminalia circa 9 cm longa, 5 — 6 cm lata, lateralia minora; petiolus 4 — 6 cm longus; petioluli 

 1 — 2 mm longi; stipulae parvae, triangulari-subulatae. Thyrsi 1,5 — 2 cm longi, pilis brevibus 

 e cinereo fiavescentibus adpresse tomentosi, dense cincinniferi; cincinni sessiles, inferiores lon- 

 giusculi, superiores contracti, 5 — 8-flori; pedicelli 4 mm longi, ad tertiam inferiorem partem 

 articulati; bracteae bracteolaeque parvulae, e triangulari breviter subulatae. Flores 2,5 mm 

 longi: Sepala duo exteriora interioribus plus dimidio minora, rotundato-ovata, pubescentia, 

 interiora subglabra. Petala superiora obovato-oblonga, in unguem longiorem attenuata, in- 

 feriora oblonga , in unguem breviorem contracta; squamae (cristis exclusis) petala dimidia vix 

 superantes, margine villosae, superiores crista tertiam squamae partem aequante obovata vel 

 obcordata margine crenulata appepdiceque deflexa cristam aequante truncata sericeo-barbata, 

 inferiores crista aliformi oblique patente instructae. Tori glandulae superiores late ovatae,
