A small genus (about six species) of stove, terrestrial Orchids, natives of the Malayan Peninsula and Archipelago, the Pacific Islands, and Australia. Flowers frequently dotted, rather large, in simple racemes; sepals and petals sub-equal, free, spreading; lip erect, adnate to the column, slightly gibbous or very shortly saccate at base, three-lobed to the middle, the lateral lobes narrow or triangular, the middle one longer; column erect, semi-terete; pollen masses two. Leaves, when present, narrow, coriaceous. Stems leafy at base, or the floriferous ones leafless. Only two species have been introduced. For culture, See Bletia. WAILESIA picta (painted). fl., sepals and petals pale ochre within, externally yellow, with reddish-brown spots, oblong, acute; lip extended in a sac, trifid, white at base, the rest pale purple, obscurely striated; peduncle above 9in. long, with a few distant sheaths, racemose at apex; bracts very short. l. oblong-lanceolate, acuminate.
