Common Name or Meaning The Upward Pointed Scaphosepalum [refers to the upward pointing pillow-like thickenings of the lip]

Flower Size .2" [5 mm] long

A plant of unknown origin as a miniature to small sized, presumed epiphyte with erect, slender ramicauls enveloped basally by 3, tubular, papery sheaths and carrying a single, apical, erect, thinly leathery, elliptic, acute, gradually tapering below into slender, keeled base leaf that blooms in the late spring on a slender, greenish to brown tinged, mottled, horizontal, arising from low on the ramicaul, provided with a few bracts, 1.6 to 6.4" [4 to 16 cm] long, successively single, to few flowered, racemose inflorescence with shorter than the ovary floral bracts.

"Scaphosepalum acutiusculum is similar to Scaphosepalum ursinum Luer 1979 but differs by the differently shaped, on the margins spinose lip, by the oblong synsepal versus the ovoid by S. ursinum, by the differently shaped »cushions« of the synsepal and by the larger petals which are thickened at the base."
