SUBGENUS Acianthera SECTION Brachystachyae Lindley 1859

Characterized by the short to elongate, but seldom prolific ramicauls [similar species with compressed ramicauls are treated in Section sicariae] carry sessile leaves with margins that are sometimes decurrent on the ramicaul. The usually short, fleshy, racemose inflorescence is terminal from the ramicaul and does not arise through an annulus but can arise from the rhizome as in the case of P johnsonii. The long to short, single to many flowered inflorescence have flowers with fleshy, often pubescent sepals whose laterals are connate. The thick, ligulate lip usually with a pair of calli on the disc is more or less broadly unguiculate and often minutely bilobulate at the delicately hinged base.
