S. lingua and S. strictiflora, it has become stabilized and clearly demonstrates a sufficient number of      individual characteristics to justify species status.

It's distribution is not dissimilar to that of S. strictiflora, being found predominantly in central Portugal and southern Spain. Given that S. lingua and S. parviflora are also widespread within this range, it's inevitable that occasional hybridisation will occur, possibly involving all three taxons. The result of such  hybridisation is the production of swarms of non stabilized intermediates that exhibit various of the characteristics from the different donor species. Certain identification can therefore be difficult and a further complication is the potential creation of "lookalikes" whose combination of inherited features mimic, that of true species. S. elsae is a frequently impersonated Serapias and although it obviously has a "type"  specification, in the field, variation can be considerable and misidentification common.

This is an unremarkable species that is slender and few flowered with bracts whose length generally exceeds the hood. The epichile is longer and fuller than that of S. parviflora and unlike S. strictiflora, has a wavy edge. The lateral lobes of the hypochile are usually red and the tongue itself a lighter, often orange shade.
