Petioles not or seldom exceeding 1.2 cm., the upper leaves often subsessile.
Inflorescence a dense spiciform raceme, 5–8 cm. long and up to 1 (–2) cm. broad, usually leafless.
Peduncles stout, often in pairs from the uppermost ocreae and rising somewhat geniculately, tomentose with ascending, whitish hairs.
