木棉科的四种观赏树木

Four kinds of Ornamental Trees in Bombacaeae

木棉、美丽异木棉、爪哇木棉和马拉巴栗四种木棉科观赏树木,由于它们的树形相似,除木棉外均为外来种,为园林工作者的应用带来了一定的困难。本文尝试对这几个树种原产地、曾用名、性状特征等方面进行比较,找出它们之间的特征区别,并简介其繁殖方法和园林用途,力求简明实用。

Bombax ceiba L.,Ceibainsignis （Kunth） Gibbs etSemir.,Ceibapentandra （L.） Gaertn.,Pachiramacrocarpa （Cham. et Schlecht.） Walp. are four kinds of ornamental trees in Bombax. There exist some difficuhies/problems in deciding how to use these trees for gardeners and designers, because their appearances are quiet similar. The paper tries to find out their difference in original producing areas, the names used, and the characteristics they have. Also the paper aims to provide clear and practical methods for these tree＇s propagation and application in design.
