Common Name The Scoop-Like Epidendrum [refers to the lip shape]

Flower Size 1.2" [3 cm]

Found in Venezuela, Colombia and Ecuador along the Cordillera Oriental de Colombia to central Ecuador, often on road embankments, and on the eastern slopes of the Andes in Ecuador, above Papallacta, on lava flows at elevations around 1500 to 3100 meters as a small sized, cool to cold growing, ascending epiphyte, lithophyte or terrestrial with a tough, repent rhizome giving rise to erect, canelike, leafy in the apical 1/3, close set, terete at the base, becoming laterally compressed above, produced near the base of the previous stem enveloped by tubular, sheaths and carrying 3 to 5, distributed along the apical 1/3 of the stem, thin, mid nerve finely and sharply sulcate, carinate, unequal, progressively larger, elliptic-lanceolate to linear-elliptic, dorsally carinate, margin entire leaves that blooms in the spring, summer and fall on a terminal, arising through a single, narrow, acute, conduplicate, open on one side towards the apex, covering the whole of the peduncle spathe, arcuate, peduncle terete, 17.7-31.8 cm long, apical, peduncle 3.08 to 5.2" [7.7 to 13 cm] long; rachis 4 to 7.52" [10 to 18.8 cm] long, racemose to paniculate, arcuate, flowering only once, lax, successively 1 to 2, 12 to 20 flowered inflorescence with elongate, narrow, fairly prominent, shorter than the ovary, linear-lanceolate, acuminate, embracing floral bracts and carrying resupinate, green with some pink flushing to yellowish green flowers with a green lip, the calli white and the fragrance was not registered

"Epidendrum trulliforme belongs to the GROUP Herrenhusanum characterized by the caespitose habit, simple cane-like stems, with few leaves along the upper half of the stem, racemose to paniculate inflorescence subtended by 1 to 2 prominent spathes covering the entire peduncle, lax, erect or arched and the bicallose, generally trilobate lip. The species has simple, slightly separated stems, 3 to 5 leaves, 1 narrow, acute spathe, a racemose to paniculate inflorescence, resupinate flowers with a trowel-shaped to somewhat hastate lip, 1-veined petals, sepals .68 to .76" [17 to 19 mm] long, and the flowers produced in succession, several being open at one time. It grows in Ecuador in the same area as E. trilobochilum Hágsater & Dodson, which has a clearly 3- lobed lip, the lateral lobes slightly smaller than the obcuneate mid-lobe which is slightly emarginate and mucronate, and the flowers are produced simultaneously. Epidendrum veroreveloi Hágsater & Dodson has smaller sepals .6" [15 mm] long, non-resupinate flowers, and an entire, oval lip. Epidendrum carlos-uribei Hágsater & E.Santiago has plants to 16" [40 cm] tall, brown-orange flowers with the lip and base of the petals yellow, sepals .68 to .84" [17 to 21 mm] long, margin revolute, petals with hyaline, erose margin, and a lip with a short fleshy mid-rib in between the calli, margin of the lip erose, lateral lobes sub-quadrate, the upper corner rounded, mid-lobe cuneate. Epidendrum cocuyense Hágsater & E.Santiago is vegetatively very similar, but the flowers are green tinged with purple, sepals .6 to .67" [15 to 16 mm] long, and the lip with a long mid-rib that reaches the apical sinus, lateral lobes are orbicular, margin entire, and the mid-lobe oblong. It is also similar to E. odonthospathum Rchb. f., but can be easily distinguished by the entire, ovate, acute lip, while the latter has a neatly 3-lobed lip, with the semiorbicular lateral lobes and the emarginate midlobe. At first sight the plant resernbles a poor specimen of one of the mernbers of the GROUP Paniculatum, but the spathes and flowers permit its separation."
