查询词典 species

The remaining three species are much more difficult, at least from herbarium material, as staminate flowers seem to offer no useful characters; leaves on flowering specimens are often young, and therefore, generally small, and in all three species the leaf shape and size is variable, with character states overlapping between the species.

Flacourtia mollis的年轻的果可以被它的叶毛被认出，剩下的3 种更难分，至少从标本馆的标本上看如此，因为雄花好像没有提供有用的特征；在花标本上的叶经常幼嫩，因此，通常小，在全部3 种中叶的形状和尺寸是易变的，在物种之间具有重叠特征状态。

The results showed that small-scale gaps were the predominant types of disturbance. The average gap density was 12.5 km^(-1). The distribution pattern of gaps was aggregated on south facing slopes and was approximately homogeneous on north facing slopes. Conifer trees were the primary gap-makers in this forest that was dominated by Abies faxoniana, Tsuga chinensis, Betida utilis, both in abundance and diameter rank. The decay class distribution of gap-makers indicated that the mode of gap formation and gap-maker species changed with age of the forest; the contribution of conifer species to gap formation decreased with time and broadleaf species increased.

结果表明：l本区以小型林隙干扰为主，林隙平均密度为12.5个km^(-1)，林隙的分布格局在阳坡和山脊为集聚分布，阴坡近均匀分布；林隙形成木以针叶树为主，岷江冷杉、铁杉和糙皮桦在形成木的数量和径级组成上均居前列。2林隙形成木的腐烂等级分布揭示出林隙形成木的形成方式和种类组成均随时间变化。
