Rhinanthus minor |
Taxonomic note: Sometimes R borealis, which occurs on Skye, is counted as a separate species, but not here. Stace (1996) lists 6 subspecies of R minor, of which R borealis is one, and adds "some populations do not fit into any of them... the subspecies may be better abandoned."

Frequent in hay fields and lowland grassland. Occasional in upland grassland and rock ledges Height c 10-50 cm. Flower length c 12-16 mm Skye ID: Unmistakable in flower. In fruit has characteristic seed-pods, as shown on left, which rattle when shaken. Plant not purplish like Louseworts. Other features: Annual parasitic plant. Stems normally black-spotted. Upper lip of flower has 2 purple or whitish teeth at tip. The roots parasitise the roots of adjacent plants (of no particular kind, as far as I know) and these sometimes respond by gall production, making Yellow Rattle the only Skye flowering plant species that causes galls on other flowering plants. |
