 his. Petal a 5, interdum 6 — 8, sub calyce occulta, 

 oblonga, brevissime unguiculata, puberula, intus supra 

 unguem squamis 2 anguste lanceolatis petala sub- 

 aequantibus vel vix dimidia superantibus villosis aucta.

 tenerrimo puberulus. Stamina 8, (in fl. tf) calyce 

 4-plo longiora; filamenta filiformia, glabra; antherae 

 breviter ellipticae, basi sagittato - excisae , in incisura 

 affixae, lateraliter dehiscentes, glabrae, subpapillosae ; 

 pollinis granula subglobosa, 3-sulcata, in mediis sulcis 

 poro notata ; stamina floris 9 breviora , germen vix 

 superantia, antheris atro-purpureis non dehiscentibus. 

 Germen e late obovato breviter cuneatum, 2-loculare, 

 a loculorum lateribus compressum, dense adpresse flaves- 

 centi-tomentellum (fl. tf rudimentarium) ; stylus brevis, 

 a loculorum dorso compressus, pugioniformis, lineis 

 stigmatosis marginalibus (suturalibus) ; gemmulae in 

 loculis solitariae, axi prope basin affixae, erectae, cam- 

 pylotropae, apotropae. Capsula late obovata, 2-locu- 

 laris, a loculorum lateribus compressa, utrinqoe sulco

 sectione 1. anomalum evadit, in subsectionem 2. potius

 sparsa, exstipulata, abrupte tripinnata, larga, petiolo

 secretoriis (ut in Dilodendro staurenchymatis tantum 

 latioribus) crebre minutim peUucido-punctata utriculisque 

 seriatis sub nervis instructa, aqua agitata mox spumam 

 efficientia, epidermidis cellulis interdum (stirpium ju- 

 venilium?) sinuatis partim mucigeris. Paniculae thyrsi- 

 formes pauciramosae ad apices ramorum in axillis 

 foliorum et squamarum, quarum superiores gemmam 

 terminalem obtegunt, confertae, petiolos aequantes vel 

 duplo superantes, ut et squamae adpresse flavescenti- 

 tomentellae, masculae tenues, femineae robustiores, ad 

 apices ramorum brevium fiores in polychasia vel dichasia 

 dense congestos gerentes; bracteae par me, triangulares,

 cellis basi articulatis.

Obs. Genns singulare, foliorum forma et fabrica ad Dilodendron 

 accedens, flore ad Mataybam, pericarpii et embryonis indole ad Sar- 

 copterygem et Jageram, genera Cupaniearum notorrbizarum (ad quas, ut 

 supra indicavi, Tripterodendron quoque transferendum) in Asia et Australia 

 obvia.
