Flores quam in reliquis Paullinieis minores, spurie polygami, subregulares, nee 

 nisi feminei quodammodo symmetrici. Calyx brevis, subeupularis, 5-partitus, seg- 

 mentis ovatis, ante anthesin basi subimbricatis, siccis subfuscis, cellulis secretoriis 

 foetis, praesertim margine puberulis glandulisque saepius obsitis. Petala 5, spathulata, 

 calycem plerumque superantia, intus villosa squamulisque villosis sublinearibus mar- 

 ginalibus divaricatis, basi vix contiguis vel in squamam bifidam coadunatis, ad mar- 

 ginem interiorem interdum crista rudimentaria dentiformi instruetis supra unguem 

 aueta, infra discum inserta. Discus parvus, subeupularis, 5-crenatus, in flore $ tantum 

 interdum inaequalis. Stamina 8 circa pistillum vel pistilli rudimentum supra discum 

 inserta, floris <$ longiora, petala plus duplo superantia, filamentis inferne villosis; 

 antherae breviter ellipsoideae, subintrorsae, dorso supra basin emarginatam affixae, 

 glabrae vel puberulae; pollinis granula e subgloboso trigono-placentiformia, ad angulos 

 poro instrueta. Germen breviter stipitatum, trigono-pyramidatum, triloculare, pube- 

 rulum, loculis basi tumidis ibidemque gemmulas singulas campylotropas, apotropas, 

 adscendentes foventibus, superne compressis et mox in alas produetis; Stylus brevis, 

 in stigma tricrure desinens, cruribus dorsalibus arcuato-patulis intus stigmatosis. 

 (Florum masculorum pistillum rudimentarium trigonum, stigmate obtuse trilobo 

 coronatum.) Fructus obeordatus vel ex obeordato euneatus, stipitatus, tricoecus, 

 sursum trialatus, alis axis ope coadunatis, apice excisus, in excisura styli reliquiis 

 coronatus, quasi Serjaniae inversus; cocci samaroidei, basi loculiferi, superne in alam 

 chartaceam, oblique reticulato-venosam, apice latiorem et styli insertionem superantem 

 produeti, maturitate ab axe persistente lineari-subulato superne denique trifido ab 

 apice ad basin soluti, glabrati, loculis monospermis semiellipticis compressis vel tumidis 

 dorso carinatis, epicarpio parenehymatico tenui, endocarpio sat crasso sclerenchymatico 

 epithelio obdueto et glanduivs clavatis (T. scandens) vel elongatis (T. compressa, para- 

 guaiensis, myriantha, obliqua), interdum in pilos multiarticulatos crispatos ( T. repanda) 

 vel elongate strictos ( T. mucronata) eramosos vel ramificatos ( T. ventricosa) resinigeros 

 evolutis ornato, rarius pilis subsetulosis tenuibus unicellularibus induto ( T. ternata). 

 Semina loculis conformia, tuberculo axis laterali ad loculorum basin insidentia, testa 

 subfusca tenui (attamen strati exterioris cellulis, fere ut in Cardios pernio, sat altis, 

 margine profunde sinuatis, inde lohgitudinaliter plicatis), exarillata. Embryo oleoso- 

 carnosus curvatus (nee »rectus«, uti Triana et Planchon dixerunt I.e.), cotyledone 

 exteriore interiorem circinato-ineurvatam amplectente, radicula sat longa, in seminis 

 dorso ad micropylen hilo approximatam descendente, plica testae profunda excepta. 

 — Frutices habitu Urvillearum, cirris (peduneulis sterilibus) apice ipsis furcatim 

 bicirrosis scandentes, foliis petiolatis semper trifoliolatis (nee nisi infimis interdum 

 foliolorum coadunatione simplieibus, trilobatis), foliolis petiolulatis, terminalibus 

 majoribus subtriplinerviis, lateralibus inaequilateris (latere exteriore latiore), penni- 

 nerviis, nervis (lateralibus) in nonnullis ( T. repanda, mucronata, paraguaiensis, sepium)

 aliis speciebus crystalla singula) foventibus obtectis, chartaeeis, glabris vel pilis plerum-
