Abstract: Based on the field investigations and laboratory examinations on V. montagnei,the authors studied its habitat and sexual reproductive system.The results were described as following:(1) the habitat of  V. montagnei is very special,which is the surfaces of rocks in a stream.Part individuals live in flooded condition constantly,but most individuals grow in the flooded condition intermittently.(2) The average number of archegonia is (18.2±6.2)(N=30) in per perichaetium,the average number of antheridia is (8.3±2.7)(N=30) in per perigonium,the average length of sporophyte is (1.8±0.17) (N=20) cm,the average length of seta is (1.6±0.16) (N=20) cm,and the average length of capsule is (0.2±0.02) (N=20) cm.(3) The development period of sporophyte in V. montagnei is between June and September among which embryo period is in June,capsule formation takes place in July,spore maturity period is concentrated on between August and September.

Key words: Vesicularia montagnei, antheridium, archegonium, sporophyte, reproductive system
