甘肃省耳叶苔科植物研究小记

回顾了甘肃省耳叶苔科苔类植物的研究历史。通过文献整理和标本鉴定,得出甘肃省耳叶苔科植物15个分类单位:细茎耳叶苔(F.bolanderi)、西南耳叶苔(Frullania consociate)、达乌里耳叶苔(Frullania davurica)、达乌里耳叶苔芽胞变型(F.davuricaf.dorsoblastos)、达乌里耳叶苔凹叶亚种(Frullania davuricasubsp.jackii)、达乌里耳叶苔小叶变型(F.davuricaf.microphylla)、皱叶耳叶苔(F.ericoides)、斜基耳叶苔(F.handel-mazzettii)、盔瓣耳叶苔(Frullania muscicola)、粗萼耳叶苔(F.rhystocolea)、陕西耳叶苔(Frullania schensiana)、中华耳叶苔(F.sinensis)、塔拉大克耳叶苔(F.taradakensis)、欧耳叶苔(Frullania tamarisci)、欧耳叶苔岷山变型(F.tamariscif.minshanensis),其中达乌里耳叶苔(Frullania davurica),达乌里耳叶苔凹叶亚种(F.davuricasubsp.jackii),欧耳叶苔(F.tamarisci)为甘肃省首次报道。将列胞耳叶苔(Frullania moniliata)移除甘肃省苔藓植物区系,编写了甘肃省耳叶苔属植物分种检索表,并对其分布特点作了初步分析。
