Based on the field investigations and laboratory examinations, a study of the population of the epiphytic dolichomitriopsis diversformis ( mitt. ) nog. in fanjing mountain reveals that its habitats are different among different host trees, but that there lies the common habitat characteristics of not more than 2m height from the bottoms of host trees trunks, less light, high relative humidity, slow wind speed, slow evaporation speed and long time of remaining humid in middle - lower tree bark ; that it is one dioecious moss species, the morphology is remarkably different between its perichaetium and perigonium, the number of its perichaetia is much more than that of its perigonia, its perigonium is difficult to find out, its sporophyte is upright, its seta is long and thin, its capsule is regular long oval and its calyptra is cucullate
摘要通過野外調查和室內觀測對貴州省梵凈山樹附生尖葉擬船葉蘚種群的研究表明,其生境因其所附生的樹種不同而有所不同,但具有共同特點:附生在樹干下部距地面2m高的范圍之內,光照弱、濕度大、風速小、蒸發量小、中下部樹皮保持濕潤的持續時間長;其為雌雄異株蘚種,雌、雄器苞形態差異明顯,雌器苞數量多,雄器苞數量少並且難于發現,孢子體直立,蒴柄細長,孢蒴規則長卵形,蒴帽兜形。The megasporogenesis and microsporogenesis of phytolacca acinosa roxb. and formation of its male and female gametophytes
