Right, genotypically albino plants of forma flavida , with yellow green leaves and pale yellowish inflorescences. Conspicuously red plants of F. brachyphylla subsp. The redness appears to be a phenotypic colour transition stage for plants with purple inflorescences, towards the end of the summer. Variation in plant height . The collection was made on Baffin Island, N.W.T. at Cormick Bay, along the beach.
Genetic factors appear to explain the paler green plants.
The deep blue green plants may well have received additional nitrogen from random sources. Leaf anatomy . Leaf cross section of F. brachyphylla subsp. Adaxial to abaxial sclerenchyma strands are absent. Abaxial sclerenchyma strands are poorly developed, in discrete, relatively narrow strands opposite the veins.
