作者叶红环（2019）在《斗篷山自然保护区石松类和蕨类植物初步研究》一文中研究指出：在野外实地调查、标本鉴定及查阅相关资料的基础上,对斗篷山自然保护区内石松类和蕨类植物资源进行初步研究,结果表明:(1)斗篷山自然保护区有石松类和蕨类植物22科64属173种(含种下分类单位),其中石松类2科5属15种,蕨类20科59属158种;优势科为凤尾蕨科、铁角蕨科、碗蕨科、蹄盖蕨科、金星蕨科、鳞毛蕨科、水龙骨科,这7个科共有128种,占总种数的81.01%,优势属为卷柏属、鳞毛蕨属、铁角蕨属、耳蕨属、复叶耳蕨、瓦韦属、凤尾蕨属。(2)由多种地理成分组成保护区内石松类和蕨类植物区系,其中科以泛热带分布占优势,共10科,占总科数的71.43%;属的区系特征以泛热带分布为主,共19属,占总属数的39.58%,说明该区石松类和蕨类具有明显的热带亲缘性,无特有属分布;种的地理成分以东亚成分为主,属东亚区系,其中以中国-日本分布亚型占优势,有52种,占总种数的30.95%,表明该区石松类和蕨类植物种的区系与日本的关系更为密切,同时属于中国特有分布的有22种,说明具有一定的地域特殊性;与其它6个地区石松类和蕨类区系相似性系数比较可知,在属级及种级水平上,皆是与梵净山亲缘关系最近,而与云南苍山亲缘关系疏远。(3)该区石松类和蕨类植物的生态类型有陆生、石生、附生、藤本和水生5类,以陆生型种类最多,共101种,占总种数的58.38%。该区石松类和蕨类主要应用价值有食用、药用、观赏等,其中药用石松类和蕨类共143种,占总种数的82.66%,以全草入药为主,且以清热解毒类种类最多;食用石松类和蕨类共22种,食用部位多以拳卷叶或根状茎为主;该区具有较高观赏价值的石松类和蕨类共有130种,可在园林绿化、盆栽、盆景山石配置、切花配叶等方面应用。(4)采用离析法和石蜡切片法对单芽狗脊营养器官进行形态解剖研究,叶为异面叶,上、下表皮细胞均为不规则型,仅下表皮有气孔器分布;叶柄维管束有2~6个,自叶柄基部向上至叶轴仅有2个较大的维管束;根状茎薄壁细胞之间有多个维管束散生分布,且富含丰富的淀粉粒;皮层在根的横切结构中占比较大,木质部的发育方式为外始式;单芽狗脊珠芽的发育过程分为3个阶段,珠芽原基的形成期、珠芽原基的分化期、成熟期。
