A third group of species with diagnostic value are the constant companions . 具有鉴别价值的第三组植物是恒有伴生种。
Constant companions are added to the character taxa to form the "characteristic species combination" for associations and higher taxa . 恒有伴生种加特征种构成群丛或更高级分类单位的“特征种组合”。

Reaumuria soongorica and haloxylon ammodendron were dominant species occupying big niche breadth , and other species are companion 2769 ) 。生态位宽度较大的红砂和梭梭为优势种,其余草本植物为伴生种。
To enrich plant materials for vegetation building , this paper also put forward the idea of exploiting the dominant herbage and companion grass of natural pasture 同时,提出开发利用相应立地条件下天然草地的优势种和主要伴生种,以丰富扩大植被建设所需的植物材料。
There are five natural sample zones of adiantum reniforme l . var . sinense y . x . lin investigated , and recorded 34 species . 10 dominant species were used to calculate the niche width of populations and the niche overlap interpopulations 调查了5个自然样地,记录了34个伴生种,取10个优势种进行种群生态位宽度与生态位重叠的计算。
