在鲁梅克斯的Eulapathum部分中，出现以下单倍体染色体数目：10、20、30、40、50、60、100。近缘的R。bucephalorus有8个。在Acetosa组中，R. scutatus有20个二倍体，R. arifolius和R. nivalis有15（cf）或16（9）。尖叶棘豆有7个单倍体。没有证据表明，在龙须草组的多倍性涉及的染色体的连贯性或断裂。由于相同染色体组的倍增而导致的“同源多倍体”应与由于杂交中不同染色体组的组合而导致的“异源多倍体”区分开。|| 摘要：L. W.尖锐
In the Eulapathum section of Rumex the following haploid chromosome numbers occur: 10, 20, 30, 40, 50, 60, 100. The nearly related R. bucephalorus has 8. In the Acetosa section, R. scutatus has 20 diploid, while R. arifolius and R. nivalis have 15 (cf) or 16 (9). Oxyria digyna has 7 haploid. There is no evidence that polyploidy in the Eulapathum section has involved coherence or fragmentation of chromosomes. "Autopolyploidy," due to a multiplication of the same chromosome set, should be distinguished from "allopolyploidy" resulting from a combination of differing sets in hybridization. || ABSTRACT AUTHORS: L.
