It appears that EH. aromaticum, Batem., was discovered in 
Guatemala by the late Ure Skinner or his Indian collectors. We 
never saw any wild specimens in any herbarium except his own. 
Yet the plant has been frequently introduced alive, and is very 
frequently seen in collections. 
Pseudobulbs oblongo-pyriform or pyriform, generally a little 
compressed, bearing a few triangular sheaths at their base, and 
with filiform strong middle-sized roots. Bracts triangular, very 
much shorter than the stalked ovaries. Substance of the flowers 
stronger than membranous, but much thinner than in the group 
of EH. alatum, Batem. Sepals cuneate-ligulate, or cuneate oblong- 
ligulate, blunt or subacute, greenish yellow, very pale. Tepals 
nearly equal, but often very much broader towards the apex. Lip 
adnate over the base of the column, trifid; the lateral lacinize 
triangular or triangular-falcate acute, shorter than the broad 
oblongo-ovate, circular or flabellate acute crisp middle lacinia. 
At the base of the lip stands a broad oblong furrowed slightly 
velvety callus, running out in the ridge of the central vein of the
