"E. campbellstigma belongs to the GROUP Ramosum SUBGROUP Platystigma characterized by the monopodial, erect plants with a clear primary stem, branching occurs from the axil of the leaves, producing short, few, small leaved branches, and these produce successive, short branches from a subapical internode, thus an old plant has numerous branches, these progressively made of fewer elements, and often lacking the juvenile, long leaves, at this stage the plant attains full flowering and often dies. The species is recognized by its large plants with narrowly oblong leaves, secondary branches with leaves 1.2 to 2.4" x .32 to .6" [3 to 6 x 0.8 to 1.5 cm], the floral bracts widely ovate, generally brownish when dried, .32 to .64" [0.8 to 1.6 cm] long, flowers apple green, the lip white, ovary arcuate, sepals ovate, acute, lip subreniform, base cordate, clinandrium as long as the column, entire. E. penneystigma has secondary and tertiary branches with leaves .6 to 2 x .28 to .6" [1.5 to 5 x 0.7 to 1.5 cm], floral bracts not imbricate, flowers white, sepals elliptic-Ianceolate, lip semicircular-flabellate. E. jefestigma Hágsater & Carda-Cruz, has flowers whitish green, lip white suborbicular, base truncate, callus bilobate." Hagsater etal 1999
