It is related to E. regelii Wettst. by having dense tentacle on the leaves, bracts and calyces, but differs from plant shorter, 3–7 cm high, without ramification, leaves smaller, 3–5 mm long, corolla yellow, the back 3–5 mm long, and labium shorter than muffle. It is also similar to E. pectinata Ten. by bracts obviously bigger than vegetative leaves, but differs from plant shorter, leaves smaller, having dense tentacle on the leaves, bracts and calyces, corolla yellow, labium shorter than muffle.
