Abstract
WithinEpilobium sect.Epilobium, a cytological analysis of 121 experimental hybrids, involving 40 species, indicates the presence of a widespread BB chromosome arrangement in Eurasia, Africa, and Australasia, as well as in North and South America less commonly. The AA chromosome arrangement, which differs from BB by one reciprocal translocation, occurs in North America, South America, and in at least three European species. The CC arrangement, which differs from AA by two reciprocal translocations, characterizes theAlpinae, a circumboreal group. Distinctive or only partly worked out chromosome arrangements occur in the EuropeanE. duriaei andE. nutans and in the North AmericanE. luteum, E. obcordatum, E. oregonense, andE. rigidum. With earlier results, the chromosome arrangements of some 65 of the estimated 185 species of the section have been established fully or partly.
