摘要
对大兴安岭三类五针松，即兴安松（ＰｉｎｕｓｈｉｎｇｇａｎｅｎｓｉｓＨ．Ｊ．Ｚｈａｎｇ）、偃松（Ｐ．ｐｕｍｉｌａ）和西伯利亚红松（Ｐ．ｓｉｂｉｒｉｃａ）进行了系统地比较形态学研究。结果表明，兴安松主要性状未超出偃松变异范畴，不应做为一新种，亦不属于偃松与西伯利亚红松杂交种。文中首次提出了松属种鳞排列模式的概念。认为广义种偃松与本亚组（Ｓｕｂｓｅｃｔ．Ｃｅｍｂｒａｅ）红松类的亲缘比与另一亚组（Ｓｕｂｓｅｃｔ．Ｓｔｒｏｂｉ）美、日五针松类似更远。
Comparative morphological studies on the three kinds (i.e. Pinus hingganensis H. J. Zhang, P. pumila and P. sibirica ) of Subsect. Cembrae of Pinus from Daxing'an mountains in China was made systematically. The result shows that the important character of P. hingganensis H. J. Zhang do not beyond the variation scope of P. pumila , neither should be a “new species” and nor should be a hybrid of Pinus pumila × P. sibirica . A new concept——Arranged Pattern of Seed-scales in genus Pinus has been firstly brought up. The authors think that the relationship of P. pumila sensu lato with the species of another Subsect. ( Strobi ) is more close than with that of one's Subsect. ( Cembrae ).
