Eulophia streptopetala flower

This Eulophia streptopetala flower has spreading, obovate sepals. Dull red spots and other similarly coloured markings predominate in parts of the otherwise yellow-green inner sepal surfaces. The smooth sepal margins show slight undulations and tip shapes wavering between pointed and rounded; the tiny mucro (short, sharp point) at the tip is usually present. The median sepal becomes about 11 mm to 18 mm long.

The petal pair manages horizontal positions, although waviness thwarts their attempts at precision. The brown markings on the petals herald the end of bloomtime. The lip is here a sagging, tripartite affair of three lobes below the pale column (Liltved and Johnson, 2012).
