Unlike the stem eelworms of cultivated plants, which have n = 12, the stem eelworms of wild plants (Picris sp., Taraxacum officinale, Hieracium pratense, H. pilosella, Cirsium setosum and Falcaria vulgaris) possess high chromosomal numbers (from n = 19 in the first to n = 28 in the latter). Due to this the stem eelworms of wild plants must be separated from the collective species Ditylenchus dipsaci. Apparently these forms of stem eelworms are distinct species polyploid in their origin.
与栽培植物的茎线虫（n = 12）不同，野生植物（毛连菜属、药用蒲公英、草地山柳菊、毛山柳菊、刺儿菜和普通丝裂果）的茎线虫具有较高的染色体数目（从第一种植物的n = 19到最后一种植物的n = 28）。因此，野生植物的茎线虫必须与茎线虫的集合种Ditylenchus dipsaci区分开来。显然，这些茎线虫的形态在起源上是不同的多倍体物种。
