Flower Size .6" [1.5 cm]

Found in the department of Antioquia Colombia without locality as a small to medium sized, cold growing epiphyte with erect, cane-like, terete stems carrying numerous, all along the stem, lanceolate, acuminate, green leaves that blooms in the late summer and early fall on a terminal, paniculate, each branch 1.2 to 2.4" [3 to 6 cm] long, erect, slightly flexuous, 4 to 6" [10 to 15 cm] long including the short, 1.2 to 2" [3 to 5 cm] long peduncle, 22 to 45 flowered inflorescence carrying simultaneously opening flowers with the tepals green, the column green basally white towards the apex, and the lip is white with a purple blotch at each side of the disc.

"Epidendrum agurrei belongs to the GROUP Pseudepidendrum SUBGROUP Paniculatum characterized by the caespitose habit with cane-like stems carrying acute to acuminate leaves usually booming on an apical inflorescence and carrying flowers with filiform petals, and a usually 3 lobed lip with 3 parallel fleshy keels, with the apical lobe often bifurcate and the "bird wing" type pollina. The species can be distinguished by its simultaneous flowers, .2 to .24" [5 to 6 mm] long sepals, .44 to .72" [11 to 18 mm] wide leaves, the lip marked with purple at the sides of the disk, and the floral bracts shorter than the ovary. The new species is closely related to E. parviflorum, which has smaller flowers, the sepals being .16 to 2" [4 to 5 mm] long, narrower leaves, .3 to .52" [7.5 to 3 mm] wide, and immaculate flowers. Other species with small, simultaneous flowers and immaculate lips are E. longibracteatum Hágsater which has prominent floral bracts often longer than the ovary; E. gratiosum Rchb. f. has a nearly repent plant habit. E. yungasense Rolfe has a longer .24" [6 mm], slender column. E. cirrhochilum Lehm. & Kraenzl has simultaneous flowers with .28" [7 mm] long sepals, and long, acuminate apical lobes of the lip some .28" [7 mm] long, the disc marked with purple. The following species have successive flowers with immaculate lips: E. macbridei C. Schweinf. usually has one flower at a time; E. subnutans Ames & c. Schweinf. has sepals about .24" [6 mm] long, with many flowers in various stages of development on a many branched inflorescence; E. poeppigii Hágsater has very long, narrow leaves 3.6 to 6.8" x .48 to .68" [9-17 x 1.2-1.7 cm].
