Description
The Begonian Oct 1960, p 225. A New Vine Begonia from Colombia - By Lyman B. Smith, and Bernice G. Schubert The vine Begonias receive little attention from horticulturists, yet it would seem that they have a beauty of their own which should recommend them in any well rounded collection. We figured three species in our "Begoniaceae of Colombia," B. maurandiae, B. tropaeolifolia, and B. spadicifiora, and Casimir De Candolle has described several attractive species from Ecuador, while the rain forests of eastern Brazil shelter still others. Although we have no living material at the moment, we should like to place the following new species on record as another example of a vine to be sought for cultivation. With all the hundreds of names already proposed in Begonia, it is difficult to find one that has not been used already, and so we have wandered rather far from the obvious characters to choose "segregata" in allusion to the two pollen sacs of the stamen that are so widely separated. Begonia (Section Gobenia) segregate Smith & Schubert, spec. nov., scandens, ramosa, gracillima; ramis Hexuosis, radicantibus, cortice persistente, rubro-brunneo, dissite minuteque glanduloso; foliis peltatis, ovatis, acuminatis, 2-4 cm. longis, 8-nervatis, laxe dentatis, marginibus sparse ciliatis exceptis glabris, petiolis 15-17 mm. longis, glabris; stipulis persistentibus, ellipticis, integris, brunneis, 2.5 mm. longis; pedunculis axillaribus, 2 cm. longis, gracillimis; cymis pauciHoris; bracteis persistentibus, ellipticis; pedicellis 5-8 mm. longis; tepalis masculinis 4, integris; exterioribus reniformibus, 9 mm. latis, roseis (!Alston), interioribus obovatis, vix brevioribus; staminibus 3-4, liberis, claviformibus, filamentis haud distinctis, thecis antherarum connectivo valde segregatis; bracteolis, femineis late obovatis, ovarium omnino occultantibus, integris; tepalis .femineis verisimiliter 5 (imperfecte visis), lanceolatis, obtusis, 1 mm. longis; stylis 3, applanato-clavatis, 1 mm. longis; ovario subgloboso, placentis non visis; capsula inaequaliter 3-alata, ala maxima valde producta, duabus alis ceteris triangularibus. Type in the herbarium of the British Museum of Natural History, collected in scrub, near Paramo, Department of Narifio, Colombia, altitude 1000 meters, May 7, 1939, by A. H. G. Alston (No. 8455). In habit, Begonia segregata closely resembles B. maurandiae A. DC, but differs from it and all known members of the Section Gobeniain the form and very small number of its stamens. The capsule sometimes has two large wings instead of one, but this is probably an abnormality.
