Memoirs of the New York Botanical Garden. New York: The Garden, 1900- v. 8 1952-1954: Page: 36-40 http://www.biodiversitylibrary.org/item/150964 Suffruticosa; ramis hirtellis vel glabris; foliis rectis, asymmetricis, lanceolatis, acuminatis, basi dimidiatis, ad 7 cm. longis et 2 cm. latis, serratis, supra omnino et subtus ad nervos hirtellis, petiolis 13 mm. longis, hirtellis, stipulis tarde deciduis, late ellipticis, 7 mm. longis, integris, apice setiferis, pallide brunneis; pedunculis 30-35 nlffi. longis; inflorescentiis paucifloris, proterandris; pedicellis masculinis 18 mm. longis; tepalis masculinis 4, subaequalibus, 12 mmo longis, retusis, rubris, exterioribus late ellipticis, juvenilibus insigniter valvatis, interioribus suboblongis; staminibus 4, liberis, antheris oblongis, ob­tusis, quam filamentis longioribus; tepalis femineis perjuvenilibus solum cognitis, verisimiliter 5, quorum uno multo minore quam reliquis; stylis multifidis, seg- mentis linearibus; ovario 3-loculato, placentis bicornutis; capsula late turbinata, apice columna alta praedita, aequa liter 3-cornuta; seminibus crasse ellipso'ideis. In general habit Begonia valvata closely resembles B. urticae, but its four stamens indicate closer affinity with B. tetrandra. From this last it differs in its subaequal retuse staminate tepals, elongate anthers, and linear style--branches. We realize that the name valvata does not signalize a particularly distinctive character in Begonia, -it just happens not to have been used before.
