Family: Bombacaceae
Barrigón
|
Description: A large tree with a tall straight trunk which is usually swollen at the base, with small buttresses below. The bark has vertical green lines, especially prominent in juveniles, but usually still visible even in large trees. Like the other Bombacaceae, the crown is concentrated at the top of the tree, and the trunk is unbranched for most of its length. Leaves are palmately compound, usually with 7 leaflets. Reproduction: A highly deciduous species, dropping all its leaves in December and regrowing them with the rains in April or May. Like several Bombacaceae, the trunk stores water during the dry season, and this is used to fill flowers and fruits. Flowers are very distinctive, a ball of white stamen that looks like a cheerleader's pom-pom. They open at night, are pollinated by bats, and fall to the ground the next morning, so during the early dry season, big Pseudobombax usually have white pom-poms beneath them. Various mammals eat the flowers. The fruits are pods with green or brown lines, maturing at the end of the dry season, when they break open to produce tiny seeds with cottony filaments. Distribution: A tree of secondary forest throughout the area, occasionally along roads and on farmland. It is common in secondary forest near Panama City, and on the limestone rock near Madden Dam, somewhat less common in the secondary woods around Gamboa and at Pipeline Rd. Scarce as a few large trees in old growth of Barro Colorado and Soberania, and rare on the Caribbean side. Like the other large Bombacaceae ( ceibpe Ceiba and cavapl Cavanillesia ), this species does not produce saplings within forest, and juveniles are seldom seen anywhere. Similar Species: LK ceibpe Ceiba pentandra, LK2 LK pochqu Pachira quinata, LK2 and LK pochse Pachira sessilis LK2 are the most similar species. None of them have the green lines in the bark like Pseudobombax. Pseudobombax has wider, more oval leaflets than Ceiba, and much smaller buttresses. As a juvenile, Pseudobombax has conspicuous green lines on the trunk and no spines; Pachira sessilis is also spineless but has no green lines. See also LK jac2sp Jacaratia spinosa, LK2 which has palmate leaves like these four Bombacaceae, but never has buttresses. Uses: This species occasionally appears in living fences in Panama's interior. The cotton-like seed filaments are used for pillows, as in Ceiba, the kapok tree. Descripción: Árbol de 20 a 35 m de alto. Copa redondeada y pequeña, concentrada en el extremo terminal del tronco, quedando el resto del mismo sin ramificación. Tronco en forma de un ‘barril’. Corteza exterior con líneas verticales verdes y lisas, interespaciadas con áreas corchosas. Hojas digitadas y alternas, con 4-9 folíolos, de 7-30 x 4-14 cm, obovados, con ápice acuminado, bordes enteros y base decurrente. Estípulas deciduas. Pecíolo de 10-40 cm de largo, pulvinado en la base e hinchados en el ápice. Flores grandes y de color blanco, con muchos estambres y de forma similar a la ‘brochita’ que utilizan los barberos. Frutos en cápsulas oblongas, de 10-18 cm de largo y con líneas verdes o marrón castaño sobre la superficie exterior, dehiscentes al madurar. Semillas envueltas en una capa de pelos algodonosos. Datos Ecológicos: La especie crece a bajas elevaciones, en lugares secos o húmedos. Común y fácil de observar en bosques secos y pastizales de la vertiente del Pacífico en Panamá, pero raro o ausente en bosques lluviosos del Caribe. Deja caer sus hojas durante la estación seca, pero las repone a inicios de la estación lluviosa. Florece y fructifica de enero a mayo. Las flores son visitadas por murciélagos, abejas, mariposas y otros insectos. Varias especies de monos comen la flor cuando todavía está en el árbol, pero a menudo el conjunto de estambres se desprende y cubre el suelo, en donde sirven de alimento a los ñeques y los venados de cola blanca. Las semillas son dispersadas por el viento. Especies Parecidas: A menudo se confunde con LK ceibpe Ceiba pentandra LK2 , pero C. pentandra tiene espinas en el tronco y los folíolos son más estrechos y delgados. Usos: La madera es empleada para postes de cercas vivas. Los pelos algodonosos del fruto se usan para rellenar almohadas y colchones. Los árboles de esta especie presentan un gran potencial como planta melífera en fincas dedicadas a la apicultura. |
