Trifolium reflexum ( 英語 )

由wikipedia EN提供

Trifolium reflexum, the Buffalo Clover,[2] is a species of clover native to the Eastern United States. It is found in areas of natural openings including woodlands, glades, and prairies, often in acidic areas.[3] It is an annual or biennial that produces white to dark pink flowers in the late spring.

Early in the European colonization of the Americas, clover species, likely including T. reflexum as well as related species such as T. stoloniferum, were recorded as forming a major component of the plant life in meadows and open woodlands, often in association with river cane, nettles, and other legumes.[4]

Like many native clovers of the Eastern United States, Trifolium reflexum's populations have declined considerably in the past 200 years. For this species, fire suppression is indicated as a significant cause for decline.[5] Controlled burns have been found to stimulate seed germination in T. reflexum.[6]

As host plant

Buffalo clover is a host plant for the caterpillars of the following butterfly species:

Trifolium reflexum ( 冰島語 )

由wikipedia IS提供

Buffalósmári, eða Trifolium reflexum,[2] er einær eða tvíær jurt af ertublómaætt, ættuð úr austurhluta Bandaríkjanna. Hann finnst á náttúrulega opnum svæðum svo sem rjóðrum í skóglendi og á sléttum, oft í súrum jarðvegi.[3] Blómin eru hvít eða dökkbleik og koma síðla vors.

Eins op margir upprunalegir smárar í austurhluta Bandaríkjanna, hefur fjöldi Trifolium reflexum minnkað verulega síðustu 200 ár. Fyrir þessa tegund er talið að skortur á gresju og skógareldum sé aðalástæða hnignunarinnar.[4]

Undirtegundir

Tegundin skiftist í eftirfarandi undirtegundir:[5]

  • T. r. glabrum
  • T. r. reflexum
