Marsh Fragrant Orchid Dunstable Downs Whipsnade end |
The lip is much wider than the usual fragrants with larger side lobes and a distinct bulge or shoulder on the side lobes.
Marsh Fragrant broad lip, shorter middle lobe, shoulder bulge. |
Normal Downland Fragrants have a narrower lip usually with the central lobe longer than the side lobes as shown below.
It is worth looking at any population of fragrants for large specimens and having a look at the lip. Hybrids do occur...and these plants show most of the features of the Marsh type...and do look different overall.
Keep looking!
