Scandens, fruticosa, subtomentosa; rami 4 — 5-sulcati, breviter sufferrugineo-tomeutosi ; 

 corpus lignosum simplex; folia 5-foliolato-pinuata; foliola superiora obovata, raro suboblonga, 

 inferiora breviter ovata vel subrotunda, terminale basi cuneatum, lateralia rotundata, omnia 

 apice breviter acuminata, apicem versus nainutim serrato-dentata, acumine ipso denticulato, 

 petiolulata, cbartacea, clathrato-venosa, subtus in axillis nervorum nee non saepe venarum 

 quoque barbata, ceterum pilis lateraliter affixis sufferugineis breviter subtomentosa (interdum 

 forsan, uti Poeppig refert, „tenuiter argenteo pubescentia") glandulisque microscopicis erectis 

 vel inclinatis obsita, denique glabrata, punctis lineolisque pellucidis sparsis supra notata et 

 reti utriculorum laticiferorum subpellucido subtus instructa, epidermide non mucigera (paginae 

 inferioris — contra sectionis rationem — non crystallophora) ; petiolus rhachisque nuda; thyrsi 

 solitarii, robusti, laxius cincinniferi, subtomentosi; cincinni sessiles, contracti, 5 — 8-flori; 

 flores mediocres, sepalis dense subcanescenti-tomentellis ; fructus sectionis pyriformis („nuce 

 Juglandis major, subglobosus, viridis, glaber" teste Poeppig), glabrescens (maturus deerat). 



Caulis „altissime scandens" (Poeppig).

 9 — 14 cm longum, 5 — 7 cm latum, lateralia pauUo minora; petiolus communis 5 — 7 cm longus 

 rhachisque plerumque dimidio brevior tomento brevi praesertim ad insertionem foliolorum 

 induta; petioluli 3 — 8 mm longi, subtomentosi; stipulae — (non visae). Thyrsi 10 — 40 cm 

 longi, subsessiles vel pedunculati, rhachi diametro 2 — 4 mm; bracteae bracteolaeque subulatae; 

 pedicelli 2 — 3 mm longi, articulati, Sepala duo exteriora interioribus plus dimidio breviora, 

 interiora subrotunda, 3 — 4 mm longa, 3 mm lata. Petala oblonga; squamae petala dimidia 

 aequantes, margine villosae, superiores crista obcordata appendiceque deflexa margine villosa, 

 inferiores crista oblique aliformi instructae. Tori glandulae superiores late trianguläres, 

 tomentosae, uti torus. Staminum filamenta filiformia, complanata, pilosa; antherae glabrae.. 

 Germen e trigono subglobosum, tomentosum.
