Marsh-orchids of Canada: long-standing mysteries partially solved.

Between 1959 and 1988, three populations of purple-flowered terrestrial orchids attributable to subgenus were discovered in Canada. The populations at Timmins, Ontario, and St John's, Newfoundland were strongly marked on both flowers and leaves, in contrast with the anthocyanin-deficient population at Tilt Cove, Newfoundland. All three populations have since experienced...

Systematic reappraisal of marsh-orchids native to Scotland.

The intensively studied Eurasian orchid genus has become a model system for exploring allopolyploid evolution, yet determining the optimal circumscriptions of, and most appropriate ranks for, its constituent taxa remain highly controversial topics. Here, novel allozyme data and detailed morphometric data for 16 Scottish marsh-orchid populations are interpreted in the...
