摘要
迄今为止,拟牛毛藓属(Ditrichopsis)在全世界共有3个种.作者近年在中国新疆天山考察时发现了一个新物种――吴氏拟牛毛藓(Ditrichopsis wui M.Sulayman),其主要特征为:(1)叶卵形至椭圆形,具长中肋和扭曲叶尖;(2)叶细胞长方形至长形,薄壁;(3)孢蒴圆柱形,闭蒴,具长喙;(4)蒴帽大,兜形,被覆整个孢蒴;(5)孢子小,直径为9~12μm.该种生境显示极端气候对其生理和形态上的适应特征产生影响.
Up to date,Ditrichopsis Broth.contains three species worldwide,Ditrichopsis wui M.Sulayman as a new species was found by the author during the recent studies from Tianshan Mountains,Xinjiang of China.Its main characteristics are:(1)Leaves are ovate to oblong-ovate,with a long costa and contorted at leaf apex;(2)Leaf cells are short rectangular to long rectangular,thin-walled;(3)Cylindrical capsules are cleistocarpous,abruptly contracted to an erect long beak at the apex;(4)Calyptras are cucullate,large,covering the whole capsule;(5)Spores are small,9∼12μm in diameter.Its habitat shows that the extreme climate might affect its physiological and morphological adaptive traits.
