Common Name or Meaning Ton's Lepanthes [Dutch son of cultivator of the type A P Sijm current]

Flower Size .4" [1 cm]

Found in Cusco department of Peru without locational data as a mini-miniature sized, caespitose epiphyte with slender, erect ramicauls enveloped by a tubular, basal sheath and carrying a single, apical, erect, coriaceous, elliptical, subacute to obtuse, cuneate below into the slender petiolate base leaf that blooms in the fall on an erect, slender, peduncle 1.6" [4 cm] long, arising low on the ramicaul, single flowered inflorescence with as long as the pedicel floral bracts and carrying flowers with rosy white sepals with a minute, dark spot at the base of the laterals, white petals and a white lip with a dark purple apex.

"This little species of SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Oscillantes Luer 1986 is an exception without a swiveling lip. The lip is immobile with a short strap that holds the base of the lip snugly against the base of the column, and the lip is enclosed by a synsepal that inhibits oscillation. The plant is small with a short peduncle that bears a nutant flowerss no higher than the base of the blade of an elliptical leaf. The tails of the sepals are terete, those of the lateral sepals being shorter than the blade; the callus of the petals is low and wing-like, and the winged lip is panduriform, similar to many others of subsection Oscillantes."
