Echeandia flavescens
Echeandia texensis
Echeandia flavescens is a highly variable polyploid complex. Most specimens from the flora fall into one of three groups: slender plants with leaves 1–4 mm wide and capsules 7–11 mm; slender plants with leaves 1–4 mm wide and capsules 12–15 mm; and more robust plants with leaves 4–9 mm wide and capsules 12–16 mm. The first plants are diploids and the last two are hexaploids and octoploids, respectively. The robust morph was described as Anthericum stenocarpum and has been collected at scattered locations throughout the distributional range of the species. Because the correlation between morphology and ploidy level breaks down across the distributional range, no infraspecific taxa are recognized.

Echeandia texensis is distinguished from E. reflexa, a common species of eastern Mexico, by the short, broad anther cone, which has a wide, broadly and deeply lobed apex. The anther cone of E. reflexa is longer and narrower, and the apex is narrower and minutely lobed.
