标题水杨树科水杨树一新种。等J. Yokoy。是来自于那个岛的Doi Inthanon。该种属与红翅有较近的亲缘关系，但其侧翼位置较中间，侧翼较少。即使在混合种群中，它的形态学、细胞学、生态学和分子特征也很容易被识别。H. inthanonense和H. cheilosorum在缓慢进化的rbcL基因上存在较大差异（约10个碱基对），表明它们在很久以前就分化为两个不同的生物物种。
A new species of Aspleniaceae, Hymenasplenium inthanonense N. Murak. et J. Yokoy. was described from Doi Inthanon, Tha iland . This species is closely re lated to H. cheilosorum , but can be distinguished by it more medial sorus position and less dimidiate pinnae. It is readily recognizable even in mixed populations by its morphological, cytological, ecological and molecular characters. The relatively large (about 10 base pairs) difference in the s lowly evolving rbcL gene between H. inthanonense and H. cheilosorum indicated that they d ifferentiated into two different biological species long ago.
