Common Name Dalstroem's Trisetella [Swedish Orchid Illustrator extrodinaire Current]
Flower Size .4" [1 cm]
Found in Imbabura province of Ecuador in wet montane forests at elevations of 2100 meters as a mini-miniature sized, cold growing tufted epiphyte with with erect, slender ramicauls enveloped by 2 thin, loose tubular sheaths and carrying a single apical, erect, coriaceous, narrowly obovate, subacute to obtuse, narrowing below into an ill defined petiolate base leaf that blooms in the late fall and early winter on a slender, erect to suberect, 1.8 to 2.2" [4.5 to 5.5 cm] long, congested, successively few flowered inflorescence arising from the base of the ramicaul witha thin bract in the lower third, and a tubular, oblique floral bract.
"This species is related to the smaller T. vittata which also occurs on the western slopes of the Andes of northern Ecuador. Because of the much larger size, a plant of T. dalstroemii superficially resembles a small Masdevallia. From the other species of the Trisetella, it is distinguished by the large, broad leaves, and comparatively large flowers that bear spreading, thickly tailed sepals. From T. vittata it is distinguished by the larger habit; purple, non-striped flowers with thrice longer tails; and proportionately larger lateral sepals." Luer 1994
