"Vegitatively variable in size but charracterized by the densely fasciculated, more or less ascending ramicauls with narrowly obovate to elliptical leaves and a sl;ender raceme often slightly longer. The tiny flwoers are subtended by proportionally long, imbricating floral bracts that contain the pedicel, ovary and the lower half of the flowers. The sepals are acute with the laterals more or less parellel. The petals are single veined and truncate at the thickened apex. The type "B" lip is tridentate with a ponted middle lobe. The apex of the moddified type "B" lip of S hymenantha is merely an acute triangle. and has shorter floral bracts that do not engulf the sepals." Luer 2009
