美洲荒野·仙人掌

Say the word ‘cactus,‘ and many people get a mental picture of a thick, straight up trunk with rounded tip, and sturdy branches curving to the vertical in a candelabra effect.
一提到仙人掌,很多人脑中就会浮现出这样一副画面:粗直的树干、圆形的顶,强健的枝干如烛台状垂直立着。

The species responsible for this image is a local monarch of the family, the patriarchal saguaro [pictured] of southern Arizona.
正是仙人掌界的主宰树形仙人掌,造成了人们的这种印象。图为南亚利桑那州的树形仙人掌。

In some 200 years of slow growth, it may attain a height of 50 feet [15 meters] and a wealth of holes and scars from the creatures it helps to shelter or feed.
通过约200年的缓慢生长,它往往能长到50英尺(15米)高,躯干上则布满了别的动物咬食或者寄宿所造成的伤痕和空洞。
