Common Name or Meaning Eduardo Perez's Epidendrum [original collector of species]
Flower Size 1.2" [3 cm]
Found in Oaxaca state of Mexico at elevations around 1400 meters as a small sized, cool growing epiphyte with an ascending to diffuse, terete, branched, cane-like, thin, straight stem carrying 2 to 3, towards the apex, articulate, distichous, subcoriaceous, narrowly lanceolate, acute leaves that blooms in the fall on a terminal, arising on a mature stem, occuring only once, racemose, arcuate-nutant, 1.2 to 2" [3 to 5 cm] long including the laterally compressed, straight, .64 to 1.04" [1.6 to 2.6 cm] long peduncle, rachis zig-zag, subspherical, simultaneously 7 to 8 flowered inflorescence with prominent, almost as long as the ovary, narrowly triangular, acuminate, amplexicaul floral bracts
"Epidendrum eduardo-perezii belongs to the GROUP Conopseum which is characterized by the sympodial growth mode, sometimes with branching stems, membranaceous to sub-coriaceous leaves, delicate, relatively small flowers, the lip bicallose, with few to many ribs on the disc of the lip, and the predominantly Mexican SUBGROUP Propinquum which is characterized by the bush-like habit with thin stems, membranaceous leaves, racemose, few flowered compact, inflorescence, and the mostly yellow or pale green flowers. The species is recognized by the short stems with 2 to 3 narrowly lanceolate, fleshy, leaves 1.48 to 2.8" [3.7 to 7 cm] long, green flowers with the apex of the column and the disc of the lip red-purple, with many green radiating thickened-veins. The plant habit is reminiscent of a short Epidendrum skutchii Ames, F.T.Hubb. & C.Schweinf., but that species has up to 48" [1.2 meters] tall plants, the stems are longer and thinner, linear to linear-lanceolate, acuminate leaves 2.2 to 6.8" [5.5 to 17 cm] long, and the flowers are greenish yellow, slightly tinged with purple, it also has radiating ribs on the lip, but not as prominent. The flowers are somewhat reminiscent of Epidendrum radioferens (Ames, F.T.Hubb. & C.Schweinf.) Hágsater, but the plants of that species are taller and more robust, 80" [2 meters] tall, with 2 to 6 elliptic leaves 2.2 to 7.6" to .56 to 2.4" [5.5 to 19 x 1.4 to 6 cm], with intense red-purple colored flowers, the lip transversally revolute and the radiating keels cream to yellow colored. Epidendrum lignosum Lex. 1825 is superficially similar, but the 3 flowers of that species, with low, parallel ribs on the disc, and no prominent radiating ribs, the flowers are also somewhat smaller, sepals .32 to .44 [8 to 11 mm] long; the leaves are fleshy, linear-elliptic."
