Common Name Lambeau's Epidendrum [Belgian Orchid Nurseryman 1900's]
Flower Size .8" [2 cm]
Found in south western Colombia in premontane and montane forests at elevations of 1200 to 2300 meters as a mini-miniature sized, cool to cold growing epiphyte with simple, cane-like, terete, somewhat reclining stems carrying 4 to 8, all along the stem, distichous, spreading, slightly arching, articulate, succulent, narrowly ovate-lanceolate, subacute, margin apically minutely ciliate leaves that blooms in the winter and spring on a terminal, arising through a single, semi-elliptic when spread, conduplicate naturally, rounded and slightly oblique apically spathe, sessile, single flowered inflorescence with much shorter than the ovary, totally enveloped by the spath floral bracts and carrying resupinate, fleshy, green flowers with the lip lustrous, reddish purple.
"Epidendrum lambeauanum belongs to the GROUP Porpax SUBGROUP Porpax, which is characterized by the sympodial, somewhat repent habit, usually forming large mats, short, cane-like stems with very fleshy, succulent, articulate, distichous leaves, single-flowered inflorescence, sessile flowers, and the lip generally reddish purple. The species is recognized by the larger, erect, plants, the stems with 4 to 6 lanceolate leaves .68 to 1.52" [17 to 38 mm] long, the flowers are cream-colored with the lip reddish purple, and the petals linear-oblanceolate. Epidendrum porpax has small plants with somewhat reclining stems, the green flowers with a lustrous, convex, reddish purple lip proportionately wider than long, the apex rounded, the .34 to .52" [8.5-14 mm] long lateral sepals obliquely adnate to the column, and the linear petals, with the margin crenate-denticulate. It has been often confused with E peperomia Rchb.f. which is vegetatively similar to E porpax but the lip of that species is orbicular-cordiform, spreading, as wide as it is long, with the apex obtuse; and known from Venezuela and Colombia. Epidendrum mathewsii Rchb.f. from Colombia, Ecuador and Peru has small, compact plants with erect stems, an orbicular-sub-quadrate lip with the apex obtuse, and linear, acute petals. The flowers of all these species are very similar, and thus best recognized by the vegetative habit." Adapted from E porpax Icones plate 1375 Hagsater etal 2010
