ris: Ovula in loculo quovis 2, collateralia, e basi interna adcendentia, 
sessilia, anatropa, raphe ventrali, mieropyle infero-postica. Bacca 
pulposa v. fere exsucea, bi-vel abortu unilocularis. Semina 4-3-2-1, e 
basi loeuli adscendenti-erecta, anatropa, testa erustacea extus inter- 
dum strato parenehymatis plus minus crasso vestita, fere semper in 
laminas 2 ventrales intra albumen replieata ibique semi-septa spuria 
efficiente, raphe filiformi secus aciem ventris seminis excurrente dor- 
Soque seminis in chalazam linearem v. disciformen producta. Albu- 
men oleoso-carnosum. Embryo rectus, axilis; radicula conica v. cylin- 
dracea, mieropyli respondente; cotyledones 2 parvi, plano-convexi, 
sibi invicem appliciti, germinatione accrescentes, crasse foliacei. 
rutices sæpe sarmentosi, scandentes, rarius erecti, ramis inter- 
dum annotinis e eaudice subterraneo tuberoso enatis; radices fibrosæ 
v. in tubera plus minus intumescentes. Folia valde heteromorpha, 
nunc integra, sepius palmato-lobata, sæpe palmato-v. pinnato v. 
bipinnato-v. biternatim secta v. foliolata : stipulæ 2, liberæ, laterales. 
Inflorescentiæ varie, sæpius oppositifoliæ, rarius pseudo-axillares 
(revera ramum axillarem terminantes) pedunculo cirrhifero v. nudo, 
nunc plane sterili et tunc in cirrhum simplicem v. ramosum plane 
converso. Thyrsi, corymbi, cymæ, rarius racemi compositi, axeos 
ramis cylindricis v. in alas floriferas conversis, pedicellis gracilibus 
V. crassis v. subnullis, sepe bracteolatis. Baccæ varie dispositæ,

grate acidula et saccharina, sæpe in vinum arte conversa. 
Plantæ per plagas totius orbis temperatas v. calidas late extensæ. 
Affinitas hine cum Araliaceis, habitu toto, facie, foliorum constitu- 
tione, illine cum Rhamnaceis, mediante Gouania sat manifesta; cum 
Meliaceis, mediante Leea, minus arcta; cum Olacineis primo intuitu 
ob stamina petalis opposita quædem esset approximatio si perianthii 
foliola Olaeinearum sepalis Proteacearum, Santalacearum et Loran- 
thacearum responderent.
