Annual herb 1-10 cm high. Glandular hairs 0.1-0.7 mm long. Stem pale, green, straw brown or more rarely reddish brown, simple or occasionally with porrect lateral branches, sparsely glandular-hairy. Leaves cauline, scattered, pale green; lamina ovate or orbicular, 1-8 mm long including the petiole, 1-4.5 mm wide, subacute or obtuse, sparsely glandular-hairy abaxially and on the margins. Flowers usually in corymbs or umbels, sometimes in short racemes, 1-ca. 23 per plant; bracts with an ovate or lanceolate lamina, 1-7 mm long including the petiole, glandular-hairy like the leaves; pedicels 0.5-10 mm long, sparsely glandular-hairy. Hypanthium globose, ovoid or ellipsoid, 0.7-2 mm long, 0.7-2 mm wide, with glandular hairs throughout and sparse eglandular hairs 0.4-0.8 mm long distally. Calyx lobes unequal (with the anterior pair longer than the rest), 0.7-1.7 mm long, obtuse or subacute, sparsely glandular-hairy. Corolla white with a yellowish green throat; lobes

paired vertically, rounded or scarcely retuse, sparsely glandular-hairy abaxially; anterior lobes obovate, slightly longer and broader than the posterior pair, ca. 1.2-1.3 mm long, 0.8-0.9 mm wide; posterior lobes elliptic or obovate, ca. 0.7-1 mm long, 0.7-0.8 mm wide; tube yellowish green, 0.8-1.3 mm long, shorter than the longest calyx lobes, sparsely glandular-hairy distally.

Column sheath yellowish green, glabrous, to 0.3 mm high and irregularly lobed on anterior side, scarcely visible on posterior side, pendulous appendages absent. Column white, seemingly adnate to the anterior side of the corolla tube, 1.8-2.5 mm long with the top ca. 1 mm free, distally angled toward the labellum, glabrous; stigmatic lobes to ca. 0.5 mm long, apparently developing while the column is hooded, erect to scarcely incurved.

have been selected as an appropriate lectotype. This material is comparable to that of K 000060054, MEL 1617989 and MEL 2256398-they are at the same flowering stage and bear white mycelia, presumably from being poorly dried following their collection-and showcases the distinctive, dark labellum, which Mueller notes on the label ("labellum atropurpureum!"). Material at TCD is also interpreted as being part of this gathering.

" that contains flower fragments, but it is unclear to which gathering they belong. Finally, there are two packets containing seeds and withered corolla fragments that must be from a separate collection to that of the type gathering, which is not in fruit. It is unknown whether these seeds are from the type population or from a different locality or, indeed, two separate localities. It is of note that there are no fruiting specimens at MEL that predate the publication of this species and Mueller did not describe seed in the protologue. Seed is also inexplicably present in the packet attached to
