Eulophia zeyheriana bluish inside petal surfaces

The nearly white, faintly bluish inside surfaces of the rounded, broad, lateral petals of this Eulophia zeyheriana flower display purple tips and idiosyncratic marginal “deformities”. The sepals behind are not as dominant in the flower as in some other specimens, the dorsal one here recurving.

The lip below is quite small. The lateral, blue-striped segments or lobes of the lip are in this plant's flowers comparatively large. The lip crest has relatively big tubercular protrusions, the colouring of the tip beyond the crest is blue only close to the crest, paler towards the margin.

Broad, pale green, membranous bracts with angular tips are positioned at the flower base on the stalk. The buds are purple and shiny, the closed sepals not quite reaching the bulb tips here (Manning, 2009; Pooley, 1998; iNaturalist; iSpot; JSTOR).
