에피덴드룸 라디칸스 Epidendrum radicans

  

에피덴드룸은 난초과의 여러해살이풀로 북아메리카 동남부에서 남아메리카 중부에 걸쳐 1,000여 종이 분포한다.

 

이 속의 종들은 주로 다른 식물에 붙어서 공기뿌리를 내놓고 자라는 착생식물이지만 에피덴드룸 라디칸스는 땅속에 뿌리를 내리고 자란다.

 

 

 

 

 

 

 

 

 

This ground-rooting orchid is a common roadside weed at middle elevations in Central America. A crucifix orchid, it is often confused with E. cinnabarinum, E. fulgens, E. ibaguense, E. incisum, E. schomburgkii, E. secundum, and Epidendrum xanthinum, among others. Perhaps the most diagnostic characteristic of E. radicans is its tendency to sprout roots all along the length of the stem; many other crucifix orchids only produce roots near the base. E. radicans is part of a complex of several orange-flowered, weedy species (including Asclepias spp.) that are unrelated but ecologically similar. Species within this group share pollinators as well as habitat, and are believed to exhibit what is known as convergent evolution, where unrelated species "converge" upon similar physical characteristics as a result of similar evolutionary pressures. - 출처 :  http://en.wikipedia.org/wiki/Epidendrum_radicans
