LATE EARLY

Common Name The Curved E nocturnum Epidendrum [in reference to the to the mid-lobe of the lip which is curved under and backwards, in this species of the Nocturnum group. Not to be confused with Epidendrum camplyoglossum which shares the same feature and belongs to the same group, but is found on the western slope of the Cordillera Occidental of the Andes]

Flower Size 2" [5 cm]

Found in southern Colombia, from the Bota Caucana, from the Cordillera Oriental of the Andes without elevational data as a small sized epiphyte with simple, cane-like, terete at base, laterally compressed towards the apex, erect, straight stems carrying 5 to 8, distributed along the apical half of the stem, alternate, sub-equal, articulate; provided with laterally compressed, striated foliar sheaths; blade elliptic, obtuse, apex narrowly rounded, sub-coriaceous, slightly dorsally carinate, upper side dark green, underside purple leaves that blooms in the late winter and early spring on a terminal, without a spathe, peduncle and rachis abbreviated, .4 to .6" [1.0 to 1.5 cm] long overall, apical, racemose, producing new racemes in successive years and the pluri-racemose successively producing one flower at a time per inflorescence with much shorter than the ovary, triangular, acute, embracing floral bracts and carrying resupinate flowers with the sepals buff colored, petals pale green, lip white, calli yellow, column green at base, apex of column white and the fragrance was not registered.

"Epidendrum campylonocturnum belongs to the GROUP Nocturnumwhich is characterized by the sympodial, caespitose plants, cane-like stems, short, racemose or pluri-racemose inflorescence without spathe, usually large star-shaped, successive flowers, with similar sepals and petals. The new species is recognized by the epiphytic habit, stems 5.2 to 8" [13 to 20 cm] tall, leaves 1.6 to 2.8" x .36 to .92" [4.0 to 7.0 x 0.9 to 2.3 cm], elliptic, obtuse, apex narrowly rounded, sub -coriaceous, slightly dorsally carinate, upper side dark green, underside purple, ovary .212" [53 mm] long, sepals .12 to .148" [30 to 37 mm] long, lip 1 to 1.08" x .52 to .6" [25 ti 27 x 13 to 15 mm], lateral lobes hemiovate, with 4 to 5 thickened, subparallel veins, bifurcate towards the margins; mid-lobe .84" x .052" [21 x 1.3 mm], 16:1 (length:width), linear-triangular, acuminate, widely revolute in natural position. It is similar to the smaller Epidendrum porphyreonocturnum which has stems 6.4 to 16" [16 to 40 cm] tall, 3 to 8 narrowly elliptic, acute leaves of similar size, 2.6 to 3.2" x .32 to .78" [6.5 to 8.0 x 0.8 to 1.8 cm], dark green above, purple on the underside, ovary 1.92 to 2.12" [48 to 53 mm] long, sepals .72 to .84" [18 to 21 mm] long, lip .48 to .56" x .48 to .56" [12 to 14 x 12 to 14 mm], the lateral lobes ovate, with 6 thickened, radiating veins, mid-lobe .348 to .36" x .08" [8.7 to 9.0 x 2.0 mm], ratio 4:1 (length:width). Epidendrum phlebonocturnum has short stems 3.6 to 4.4" [9 to 11 cm] long, laterally compressed, bright green, 5 to 6 unequal leaves, .6 to 2.8" x .44 to .92" [1.5 to 7.0 x 1.1 to 2.3 cm], ovary about as long as the 42-46 mm long sepals, deeply 3-lobed lip, with large yellow calli, and the lateral lobes with prominently raised veins radiating from the base and sub-parallel, mid-lobe .92" x .1" [23 x 2.5 mm], ratio 10:1. Most other species do not have prominently raised veins on the lateral lobes of the lip, they are flat. In the area you can also find Epidendrum platynocturnum Hágsater & R.Jiménez has stems 2.4 to 4.8" [6 to 12 cm] long, laterally compressed, leaves 1.2 to 2" x .36 to .48" [3 to 5 x 0.9 to 1.2 cm], narrowly elliptic, acute, dark green above, slightly reddish on the underside, ovary .128" [31 mm] long, sepals .6 to .64" [15 to 16 mm] long, lip .36 x .22" [9.0 x 5.5 mm], shallowly elliptic with lobes proportionately wide, mid-lobe .16 x .08" [4 x 2 mm], ratio 2:1. Epidendrum minus (Cogn.) Hágsater has stems 4 to 8" [10 to 20 cm] long, leaves 2 t o3" x .32 to .48" [5.0 to 7.5 x 0.8 to 1.4 cm], green on both sides, ovary .12" [30 mm] long, sepals 8.4 to 9.2" x 1.6" [21 to 24 x 4.0 cm] (Cogniaux 1907), it is found at lower altitudes in the upper Amazon basin. Epidendrum ramiro-medinae Hágsater & L.Sánchez, also from Putumayo in southern Colombia, with the underside of the leaves purple, has larger flowers, ovary 3 to 3.12" [75 to 78 mm] long, sepals 3.6 to 4" [90 to 100 mm] long, lip mid-lobe .272 to .3" x .1 to .12" [68 to 75 x 2.5 to 3.0 mm]. ratio 25:1, ensiform, straight. Epidendrum campyloglossum P. Ortiz & Hágsater is very similar in size and color of the leaves but is found on the western slope of the Cordillera Occidental of the Andes, in addition that species is distinguished by the much wider petals, .16" [4 mm] wide, and the longer leaves, 4 to 4.6" [10.0 to 11.5 cm] long."
