LATE 
Common Name Ruprecht's Stelis [German Orchid Enthusiast 1800's]
Flower Size .24" [6 mm]
Found in southern and southeastern Brazil on rocky cliffs at elevations of 1100 to 1600 with trees as a mini-miniature sized, cool growing epiphyte with clustered ramicauls enveloped by 2 to 3 tubular sheaths and carrying a single, apical, erect, coriaceous, acute to subacute, cuneate below intothe petiolate base leaf that blooms late fall and winter on an erect, distichous, slightly flexuous, laxly, 2.8 to 4" [7 to 10 cm] long including the 1.6" [4 cm] long, peduncle, mostly simultaneousl many flowered inflorescence with lanceolate, acute floral bracts.
"This variable species, frequent in Brazil, is also frequent in central Bolivia. There being no distinguishing morphological feature, the species is identified by a commonly seen small, caespitose habit; elliptical leaves surpassed by a raceme of small flowers that are either yellow or purple; obtuse 3-veined sepals; petals 3-veined, often thick with a transverse callus, with intermediate variations that occur at random; and a classical type A lip, that is, round at the apex, concave below the bar, and with a round callus on the dorsum. Stelis ruprechtiana Rchb.f. is similar to Brazilian S. parvifolia Garay (a replaced name for S. microphylla Hoehne & Schltr.), but the petals are three-veined with a transverse carina, instead of thin, subcircular and single-veined."
