North american dwarf shrub resembling mountain laurel but having narrower leaves and small red flowers ; poisonous to young stock 北美矮灌木,類似山月桂,但有更窄的葉子和小紅花;對(duì)年幼的樹(shù)干有毒。
The characteristics and application in landscape architecture of the groundcover plants are described in four groups , i . e . , ferns , grasses , dwarf shrubs , and vines 分類介紹了蕨類、草本類、矮灌類和藤蔓類4類鄉(xiāng)土地被植物的特點(diǎn)及其在園林中的配置應(yīng)用。
It is dominated by low - growing prickly dwarf shrubs and aromatic herbs ( most commonly of the lamiaceae ) , such as lavender ( lavandula vera ) , sage ( salvia officinalis ) , and thymes ( thymus ) , many with droughtresistant foliage 此地區(qū)富產(chǎn)生長(zhǎng)緩慢、多刺的矮灌木以及草本香料植物(一般多為唇型科植物) 。
Negative segregation may occur between dwarf shrubs with similar habitat requirements . intensive interspecific competition may result in random or even uniform distribution , therefore , such species - pairs are apt to be negatively segregated 許多具有相近生境需求的種對(duì)(如小灌木)存在負(fù)分離,較強(qiáng)的種間競(jìng)爭(zhēng)可能導(dǎo)致隨機(jī)或均勻分布,因此這些種對(duì)表現(xiàn)出負(fù)分離。
