Glomera microphylla J.J.Sm., Bull. Jard. Bot. Buitenzorg, sér. 2, 13 (1914) 61

Type: Pulle 1065 (holo BO; iso L)

Stems elongated, strongly branched, when dried laterally compressed, 90 cm long, branches widely patent, more or less incurved, re-branched, terete, to 7.5 cm long, internodes to 1.6 cm long, on the branches 0.15-0.2 cm long. Leaves very small, widely patent, recurved, at the base half-twisted, ovate, unequally obtusely 2-lobulate, at the base shortly petiolate-contracted, above on either side of the small longitudinal channel convex, thickly coriaceous, 0.23-0.55 by 0.2-0.37 cm; sheaths tubular, strongly warty, at the apex appressed and flexuose setose-ciliate. Inflorescence 1-flowered, reflexed. Spathe and floral bract tightly tubular, thin-textured, much shorter than the ovary. Spathe obtuse, keeled, sparsely verrucose, 3-nerved, 0.95 cm long. Floral bract longer, obtuse, 1.2 cm long. Flower well-opening, thin-textured. Median sepal lanceolate-linear, gradually narrowed, at the apex recurved, narrowly obtuse, subulate-apiculate, at the base 3-, above the base 5-nerved, 1.33 by 0.27 cm. Lateral sepals widely patent, at the apex recurved, obliquely sublanceolate-linear, gradually narrowed towards the apex, subulate-acuminate, at the base shortly connate, obliquely auriculate, dilated, concave, clasping the base of the spur, at the base 3-, above the base 5-nerved, 1.35 cm long, along the front margin 1.45 cm long, almost 0.3 cm wide. Petals sublinear, narrowed at the apex, narrowly obtuse, at the base 3-, above the base 5-nerved, 1.2 cm long, 0.16 cm wide. Lip at the base adnate to the column, cucullate, clasping and distinctly surpassing the apex of the column, when flattened to the apex of the ovary 0.5 cm long, free part in outline broadly triangular, at the apex slightly prolonged, obtuse, minutely apiculate, at the base broad, subtruncate, irregularly subcrenulate, crispate, thin-textured, slightly thickened at the base, indistinctly 2-umbonate, c. 7-nerved, 0.43 by 0.47 cm; spur appressed to the ovary, slightly curved, very long, very slender, obtuse, dorsally channelled above, 2 cm long. Column at the base adnate to the lip, straight, thickened at the apex, dorsally convex, at the apex broadly obtuse, 0.25 cm long, clinandrium deeply concave, with wavy margin. Anther cucullate, suborbicular, long rostrate, recurved at the apex, thecae convex, separated by a small, longitudinal, rather broad channel, connective at the base transversely thickened, membranous, 0.12 cm wide. Pollinia 4, obliquely pear-shaped, outside convex, inside almost flat with a longitudinal groove. Rostellum at the base triangular, subulate-acuminate, slightly incurved, convex underneath. Stigma rather small, together with the rostellum obliquely cup-shaped, with the lower margin 2-lobed. Ovary 3-grooved, 1.2 cm long, including the pedicel elongated-clavate, slightly curved, sparsely furfuraceous-finely punctate, 2.2 cm long. (After Smith, 1915).
