Epidendrum parviflorum is a small-flowered reed-stemmed Epidendrum orchid found in the montane tropical wet forests of Bolivia (including Cochabamba), [1] Ecuador, and Amazonas, Peru. [2]

Description

As with other members of the subgenus E. subg. Spathium, the inflorescence of E. parviflorum erupts from an enlarged spathe at the apex of an un-swollen stem covered by alternate foliaceous sheaths. The linear-lanceolate acuminate leaves [3] grow up to 8 cm long and 1.2 cm wide. The paniculate inflorescence bears numerous 2 cm green flowers. The leathery sepals are 10 mm long and concave toward the dilated acuminate end, where they are 2–3 mm wide. The filiform petals, also dilated toward the end, are 10 mm long and less than 1 mm wide. The lip bears rounded lateral lobes, and divides into two triangular points at the apex. The callus is purple.

Synonymy and homonymy

Kew lists two synonyms: E. gramineum Lindl. and E. patulipetalum Schltr. . [4] Reichenbach 1861 listed E. gramineum Lindl. as a separate species, [5] in the subgenus he called Euepidendrum Lindl. , a taxon of reed-stemmed Epidendrum plants with inflorescences that lack any spathe or sheath at the base; the description does not specifically mention the base of the inflorescence.

The binomial Epidendrum parviflorum has also been published for two additional species:

<i>Epidendrum <span style="font-style:normal;">subg.</span> Spathium</i> Subgenus of orchids

John Lindley published Epidendrum subg. Spathium of the Orchidaceae. According to Lindley's diagnosis, the E. subg. Spathium is recognizable by is sympodial habit with individual stems being slender and covered by the bases of the distichous leaves, by the lip of the flower being adnate to the column to its apex, and by the inflorescence emerging from at least one spathe, similar to nearly all members of the genus Cattleya as understood in the year 2000. Reichenbach recognized 52 species in this subgenus, of which Kew accepts 48 :

Epidendrum subsect. PaniculataRchb.f. 1861 is a subsection of section E. sect. Planifolia of subgenus E. subgen. Epidendrum of the genus Epidendrum of the Orchidaceae. Plants of E. subsect. Paniculata differ from the other subsections of E. sect. Planifolia by producing paniculate inflorescences. In 1861, Reichenbach recognized eighteen species in this subsection. From this group, Kew recognizes seventeen species :

It differs from section E. sect. Polycladia by bearing inflorescences that are racemes, not panicles. It differs from section E. sect. Schistochila by having a lip with no lobes. Like the other sections of E. subg. Amphiglottium, plants of E. sect. Holochila exhibit slender stems covered with close imbricating sheaths which do not swell to form pseudobulbs, and terminal inflorescences covered at the base with close imbricating sheaths but without spathes.
