对鬼针草属(Byblidaceae)的6种植物进行的细胞学研究支持最近从Byblis liniflora salisb内分离出的分类群。并证实了先前报道的巨藻S的数量为2n=18。和2n=32，多花甜菜B.liniflora S Str.BYBLIS sp.11月AFF。巨型茶树的染色体数目为2n=18，而B.filifolia Planch.、B.rorida Lowrie&Conran和B.Aquatica Lowrie&Conran的染色体数目为2n=16。这就给出了B.liniflora复合体的碱基计数为x=8，B.Gigantea复合体的碱基计数为x=9，B.liniflora为四倍体。
Cytological studies carried out on the six species of Byblis (Byblidaceae) support the recent separation of taxa from within the Byblis liniflora Salisb. complex, as well as confirming the previously reported numbers of 2n = 18 for B. gigantea s. str. and 2n = 32 for B. liniflora s. str. Byblis sp. nov. aff. gigantea also has a chromosome number of 2n = 18, whereas B. filifolia Planch., B. rorida Lowrie & Conran and B. aquatica Lowrie & Conran have counts of 2n = 16. This gives base counts of x = 8 for the B. liniflora complex and x = 9 for the B. gigantea complex, with B. liniflora as a tetraploid.
