Epidendrum spruceanum
''Epidendrum spruceanum'' is an epiphytic reed-stemmed ''Epidendrum'' orchid native to the Tropical rainforest of Peru, Bolivia (including Santa Cruz and Cochabamba, where it has been found at an altitude of 0.3 km), and Brazil.
== Description ==
''Epidendrum spruceanum'' Lindl. (1853) is closely allied to ''E. nocturnum'' Jacq. (1760); although accepted as a separate species, for example, by Kew〔http://apps.kew.org/wcsp/acceptedRef.do?accepted_id=69604&repSynonym_id=-9998&name_id=69604&status=true〕 and by Dodson & Vásquez 1989,〔C. Dodson & R. Vásquez: "EPIDENDRUM SPRUCEANUM Lindl.", Plate 0336 of ''Icones Plantarum Tropicarum, SeriesII: Orchids of Bolivia.'' Missouri Botanical Garden, St. Louis. 1989〕 it is recognized as a synonym for ''E. nocturnum''Jacq. (1760) by others, for example IOSPE〔(The Internet Orchid Species Photo Encyclopedia )〕 and Reichenbach 1862〔"Huc'': Epidendrum Spruceanum'' Lindl. l. c. 253", H. G. Reichenbach "Orchides" item 322 in C. Müller, Ed. ''Walpers. Annales Botanices Systematicae'' VI(1862) p. 404. Berlin.〕 As with other members of ''E''. subg. ''Epidendrum'', ''E. spruceanum'' has slender stems covered by close sheathes, leaf-bearing above, and an apical inflorescence with a peduncle which is not covered at its base by any sheath other than the base of the last leaf. In the case of ''E. spruceanum'', the stems are rather flattened and can grow to 1 m tall, the oblong-obtuse leathery leaves grow to 12 cm long, "as large as in the largest state of ''E. nocturnum''" according to Spruce, as reported in Reichenbach, 1861. The inflorescence is short, completely covered by the basal sheath of the apical leaf, and produces one open flower at a time. The white to greenish white flowers measure 15 cm across with an ovary 20 cm long and a nectary 15 cm long. The petals and sepals are linear-acuminate. The trilobate lip is adnate to the column to its apex, with semirhombate lateral lobes and a slender central lobe with a short keel near the lip.
