L. anthyllopsis is similar to L. pentaphylla and L. bolusii but may be distinguished by the much larger flowers, inflorescences and bracts. It differs from L. rosea also in the colour of the flowers (yellow, not pink).
Like L. pentaphylla but leaves 3-foliate, inflorescences > 22 mm across (vs. < 20 mm across), flowers 10 mm or more long (vs. < 10 mm long), and bracts large, lanceolate to broadly ovate.
