====================================
本属简介:魔南景天属是小型多肉的亚热带植物,隶属于景天科。其中有十余种是加那利群岛和塞维志(?Salvage,暂无中文官方译名)群岛的当地特有品种,还有其他一些品种分布在马德拉群岛。魔南景天属的多样性分布中心位于加那利群岛的特内里费岛,这里是本属7个品种的原产地。而在菲尔提凡图拉岛和兰扎罗特岛上,仅出产M. laxiflora一种。
Monanthes is a of small, succulent, subtropical plants of the Crassulaceae family. The about ten species are mostly endemic to the Canary Islands and Salvage Islands, with some found on Madeira. Its center of diversity is Tenerife, with seven species occurring on this island. On Fuerteventura and Lanzarote, only M. laxiflora occurs.
本属不抗霜冻。和长生草属、Greenovia属(此属暂无中文译名,不同生长时期外观差别很大,有兴趣的同学自行google下,之前是从张彬大那里学到的)、Aichryson 属(依然暂无中文译名)和莲花掌属有亲缘关系,这一点显而易见滴反应在它们类似的花型上。
Monanthes are not frost-resistant. They are linked with the genera Sempervivum, Greenovia, Aichryson and Aeonium, which is obvious from their similar flowers.
本属不同品种的生活型和生长型差异明显。比方和属内其他品种差别较大的M. icterica,即为一年生植物,而其他本属植物则为多年生。
Species of Monanthes differ considerably in life- and growth-form. M. icterica, which is also genetically quite distant to other Monanthes species, is annual, while the other species are perennial.
魔南景天属是一个很罕见的物种迁移例子——在它们的祖先从陆地拓殖到岛屿之后,其后代又从岛屿转移到陆地。
Monanthes is a rare example where a species re-colonizes the continent from an island, after their ancestors have colonized the island from the continent.[citation needed]
