Common Name Ruiz's Epidendrum [Spanish Botanist 1700's]

Flower Size 3/4" [2 cm]

Found in Venezuela, Colombia, Ecuador, Peru and Bolivia on steep, rocky slopes in full sunlight at elevations of 1200 to 3100 meters as a robust, large sized, cool growing terrestrial or epiphyte, with erect, cane-like leafy stems carrying oblong, emarginate, coriaceous, graduated in size from the base leaves that blooms from summer through spring on a terminal, nodding, 6" [15 cm] long, subtended by many conspicuous imbricate, lanceolate, acute, compressed bracts that form a compound spathe, congested, successively opening, many flowered paniculate inflorescence arising on mature canes and has fragrant flowers.

Not to be confused with Epi nutans Sw. 1788 which is found only in Jamaica, Colombia, Venezuela and Brazil.

"Epidendrum nutans Sw., endemic to Jamaica, has spathe, wider petals, a clearly 3-lobed lip with the mid-lobe much narrower than the width between the lateral lobes, emarginate and forming a pair of small triangular lobes and thus belongs to the Viridipurpureum subgroup of the Paniculatum group. Epidendrum lindbergii Rchb.f. though confused with E densiflorum has a spathe and wider, oblanceolate-spatulate petals, , .4 x .12" [10 x 3 mm], .4" [10 mm] long sepals, an entire lip, reniform with the base deeply cordate, and the apex widely emarginate and a pair of short incisions on the sides so as to suggest an incipient, short midlobe. Epidendrum dipus Lindl. has a pair of very prominent spathes at the base of the inflorescence, which paniculate with fewer flowers, petals narrowly spatulate, lip clearly 3-lobed with the mid-lobe slightly narrower than the width between the lateral lobes."
