Harvard University MERRILL & PERRY, PLANTAE ARCHBOLDIANAE, XI v. 24 (1943): Page 41-59 http://www.biodiversitylibrary.org/item/33600 Planta 50 cm. alta; ramulis ferrugineo-hirsutis, pilis ±4 mm. longis; foliis ± 16 cm. longis et 7 cm. latis, ellipticis, utrinque angustatis, apice acuminatis, acumine ± 2 cm. longo, basi inaequalibus, in latere exterior in lobum breven 5 mm. longum rotundatum productis nervis basalibus 3, interiore cuneatis vel rotundato-cuneatis nervo basali uno, lateralibus utrinsecus 4 vel S, margine subsinuatis remotiuscule denticulatis setulosis, supra conspersissime pilosis vel glabris, subtus costa nervisque sparsim hirsutis; petiole circiter 1 cm. longo hirsuto; stipulis linearibus apice in setam longam productis, 1.2 cm. longis, hirtellis; inflorescentiis terminalibus flores ♂ aut ♀ gerentibus; inflorescentiis ♂ dichotomo-ramosis 8 cm. longis et 12 cm. latis ± 30-floris, ramulis sparsim hirtellis vel sursum fere glabris; floribus pedicellatis; tepalis 2 suborbicularibus 5-7 mm. diametro, extus basim versus sparsim pilosis; staminibus 25-30 basi breviter connatis, filamentis antheris subaequilongis, antheris 1 mm. longis oblongis emarginatis, rimis ½ antherae aequilongis; inflorescentiis ♀ bifloris; pedicellis 3 cm. longis sparsim pilosis; tepalis verisimiliter 5 ( 3 tantum visis) late ovatis 1 cm. longis; stylis 3 basi breviter connatis apice in crura 2 brevia patenti-erecta spiraliter papillosa fissis; ovario 1.5 cm. longo ellipsoideo; alis 3 inaequalibus ultra ovarium 3 mm. productis, una majore rotundata 7 mm. medio lata, 2 minoribus subtriangularibus 5 mm. medio latis. In several characters, this plant seems to agree with Begonia filibracteosa Irmsch., but the staminate inflorescence is distinctly dichotomously branched, the flowers have fewer stamens with longer lines of dehiscence, and the ♀ flowers are practically glabrous, although when younger they may have had a few scattered hairs.
