Leaves one to several, linear to ovate, often with a distinct pseudopetiole; lamina glabrous, green, sometimes spotted darker green adaxially or sometimes with purple markings at base or abaxially. Peduncle erect to slightly curved, usually somewhat longer than the leaves. Inflorescence a short raceme, relatively lax with up to 40 flowers; pedicels patent to erecto-patent, short.

” is derived from the Latin verb “occulere”, meaning: “to conceal”. Plants of this genus are concealed in several ways. Plants are very small and are thus easily overlooked. Also, leaves and other aboveground plant parts are produced for a very short time span every year. Finally, at first sight these plants may easily be confused with
