3a. Andreaea rupestris ssp. rupestris    岩生黑藓原亚种   yan-sheng hei xian yuan-ya-zhong
Andreaea likiangensis Chen, Acta Phytotax. Sin. 7(2): 103. 1958. Type. China: Yunnan, Li-jiang Co., W.-S. Hsu 335a (holotype PE).
Plants are autoicous, usually blackish green to black, sometimes reddish black. Leaves are lanceolate from an ovate base. Papillae of laminal cells sometimes are not distinct.
Andreaea rupestris ssp. rupestris is different from A. rupestris ssp. fauriei by having ovate to ovate-lanceolate leaves and by its autoicous sexual condition. Plants of A. rupestris ssp. rupestris are often blackish, while those of A. rupestris ssp. fauriei are often reddish.
