5201 Epilobium L.

GBIF

Notes: Hoch: The epilobiums and [Chamerion] included here are (possibly with some exceptions) 2n = 36. It is not completely clear if this is a diploid or a tetraploid number. Our current best data (Baum et al. 1994) suggest that n = 18 is the base number in Epilobieae, with all other numbers in the tribe (n = 30, 19, 16, 15, 13, 12, 10, and 9) derived from n = 18 secondarily. The number must ultimately have come from some lower number (the outgroups for Epilobieae have x = 11 and x = 7) but there are no near basal species with n = 9.

Elven: There are some reports of 2n = 18 in Epilobium (e.g., in E. alsinifolium, E. anagallidifolium, and E. ciliatum, see below). We have therefore indicated the common 2n = 36 as '4x?'.
