Abstract: Based on field investigation, specimen identification and literature review of plants in western Sichuan. Two varieties and one subspecies were reported as new distributive records in Sichuan Province. These three newly recorded plants belong to 3 families and 3 genera, including Hypericum monanthemum subsp. filicaule (Dyer) N. Robson, Gentianopsis paludosa var. alpina T. N. Ho and Rubus frachetianus var. pubescens (Franchet) C. Gapta et S. S. Dash. The voucher specimens were deposited in the Herbarium of the Chengdu Institute of Biology, Chinese Academy of Sciences.

  • 在对川西高原生物多样性的调查过程中，通过野外调查、标本鉴定并查阅有关文献[1-13]，确定纤茎遍地金（Hypericum monanthemum subsp. filicaule (Dyer) N. Robson）、高原扁蕾（Gentianopsis paludosa var. alpina T. N. Ho）、柔毛莓叶悬钩子（Rubus frachetianus var. pubescens (Franchet) C. Gapta et S. S. Dash）3种为四川新分布植物。这些分类群的发现，丰富了四川种质资源、物种多样性，对相关植物区系的研究具有一定意义。新分布类群的凭证标本存于中国科学院成都生物所植物标本馆（CDBI）。现进行报道如下。

    • 1.   新记录种

      1.1.   纤茎遍地金（藤黄科，金丝桃属）

    • Hypericum monanthemum subsp. filicaule (Dyer) N. Robson, Bulletin of the Natural History Museum, London (Botany) 31(2): 78, f. 14B, map 11. 31: 78. 2001.

      主要特征：本种为植株矮小纤弱的草本，萼片和花瓣4，萼片不等长，通常叶状，全缘，外轮2枚萼片较大，其长度约与花瓣近等长，花瓣花后不脱落，可与其他近缘种相区别。

      凭证标本：鞠文彬，郑臣臣 THP-KD-6606，四川省康定县老榆林乡日乌且到电站草地灌丛。

      分布：西藏、云南[1,4,7]。四川分布新记录。

      Figure 1.  Hypericum monanthemum subsp. filicaule (Dyer) N. Robson；A. holotype B. plant C. flower D. sepals

      • 1.2.   高原扁蕾（龙胆科，扁蕾属）

    • Gentianopsis paludosa var. alpina T. N. Ho in Acta Biologica Plateau Sinica 1: 41. 1982.

      主要特征：本种茎从基部分出，茎叶片长圆形到椭圆状披针形，花黄色或黄白色，常具蓝色条纹，可与其他近缘种相区别。

      凭证标本：鞠文彬，郑臣臣 THP-KD-6109，四川省康定县贡嘎山乡莫溪沟。

      分布：青海、西藏[2,3,5,8]。四川分布新记录。

      Figure 2.  Gentianopsis paludosa var. alpina T. N. Ho；A. holotype B. plant C. flower

      • 1.3.   柔毛莓叶悬钩子（蔷薇科，悬钩子属）

    • Rubus fragarioides var. pubescens Franchet, Plantae Delavayanae 203. 1890

      主要特征：本种叶片两面脉上和花萼有柔毛，花枝和花梗具柔毛而无脉毛，可与其他近缘种相区别。

      凭证标本：余奇、熊先华、李琳霖 THP-KD-483，四川省康定县捧塔乡捧塔村磨子沟; 高信芬，郑臣臣 THP-KD-4925，四川省康定县贡嘎山乡玉龙西村。

      分布：云南、西藏[1,6,9]。四川分布新记录。
