| 摘 要： | 通过野外调查和室内观测对贵州省梵净山树附生尖叶拟船叶藓种群的研究表明,其生境因其所附生的树种不同而有所不同,但具有共同特点:附生在树干下部距地面2m高的范围之内,光照弱、湿度大、风速小、蒸发量小、中下部树皮保持湿润的持续时间长;其为雌雄异株藓种,雌、雄器苞形态差异明显,雌器苞数量多,雄器苞数量少并且难于发现,孢子体直立,蒴柄细长,孢蒴规则长卵形,蒴帽兜形. |

| Abstract: | Based on the field investigations and laboratory examinations,a study of the population of the epiphytic Dolichomitriopsis diversiformis(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 perigoniumt,he 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. |
