Identify this weed ?

writes In message , writes and it is both ancient and has 216 chromosomes, the highest I think found to date. Fide Wikipedia, the Adder's Tounge Fern has approximately 1,400 chromosomes (it's hard to count them when there's that many). Turns out that Wikipedia is inconsistent. Another page says 1,200 or 1,260 for Ophioglossum reticulatum - a particular species of Adder's Tongue Fern. Tilia nobilis has 328 (abstract to C.D. Piggott, A Review of Chromosome Numbers in the Genus Tilia (Tiliaceae), Edinburgh Journal of Botany 59: 239-246 (2002)) -- Stewart Robert Hinsley |
