RECOGNITION: Epidencfrum lacustre belongs to the Excisum Group, Leucochilum Subgroup, characterized by the caespitose plants with

cane -like, erect stems, fleshy leaves, the base of the inflorescence with 1-2, spathe- like bracts, star-shaped flowers with narrow sepals and

pctals, and a prominent, acuminate, lip. The species is recognized by the

, laterally compressed to ancipitose stems, generall y wide, occasionally

imbricating leaves, to 7 cm wide, racemose, 5-15-flowered, inflorescence,

sepals and petals green, light green to yellowish gree n, lip, ca lli and

column white, the midlobe rarely green, the lip obscurely to clea rly 3-

lobed, without deep sini separating lhe midlobe from the lateral lobes,

di sc of the lip with a centra l keel running down to the midlobe.

Epidendrum leucochilum Link, Klotzsch & Otto, ranges in the Andes of

Venezuela to southern Ecuador on the western Andes, has terete to

somewhat compressed, but not ancipitose stems, cori aceous leaves, and

the 3- lobed lip is divided by deep si ni, the lateral lobes transversely ovoid,

and the midlobe li gu late, acute. Epidendrum lehmannii Rchb.f. similar to

the latter species, ranges on the eastern Andes of Ecuador and Peru, has

few, very wide leaves and smaller flowers. The sta r-shaped flowers are

reminiscent of Epidendrum nocturnum Jacq. which lacks spathaceous

bracts, and produces several, distichous, apical inflorescences which

develop one flower at a time over severa l years.
