The hairs of Asclepias begin to bend significantly at a wind speed of 0.5-0.9 m s-1, and have an angle of attack of almost 90° at wind speeds of 4.0-5.1 m s-1. The stomata density on Jl. Economically important timber tree, it is native to a number of North and South American countries including the USA, Mexico, Bolivia and central Brazil [3]. The aesthetics of the wood, its physical characteristics and ease in woodworking have paved the way for use mainly Wood characteristics Swietenia macrophylla is a rather soft, medium-weight timber. Well established mahogany sapling (held by a person) in an abandoned slash-and-burn agriculture (SBA) field. This majestic tree can live upward of 350 years. Swietenia macrophylla.

An evergreen tree, S. macrophylla is long-lived and slow-growing and can grow up to 35-40 m tall, with a girth of 3-4m. The difference in stomata density in both locations was significant. The mean weight of a capsule was 369.47 (:I: 54.01) g, ranging between 231.13 (:I: 25.67) g and 565.55 (:I: 72.82) g. On average a capsule contains 43 germinable seeds.

Swietenia macrophylla. The selection of parent trees having larger capsules appears to be most promising for seed collection. Ringcharacteristics ofmahogany(Swietenia macrophylla K.) plantation treesgrown inTaiwan were explored. The project is aimed at quantifying genetic variation and relating it to population characteristics. The method of stomata observation was a replica method. The variation in seed weight, germination percentage and germination period could be due to provenance differences, size of capsules, crown size of parent trees, level of seed maturity, site fertility, health condition of parent trees and environmental factors of a locality. The type of stomata found was anomocytic. Due to the past indiscriminate felling, the mahogany of this species is not any more commercialized, it is available only rarely and in limited quantities, mostly coming from small African plantations; presently, the mahogany utilized comes almost exclusively from the Swietenia macrophylla, native to continental America, from Mexico to Bolivia and Brazil.
