S. behrii (Reichb.f.) Benth. & Hook. ex Hemsl. Caespitose epiphyte, to 45 cm tall; stems densely clustered and slender, consisting of several superimposed, weakly swollen, finely ridged segments (the lower segments most slender), occasionally branched, the old leafless stems persisting. Leaves usually 2, near apex of each segment, usually only the uppermost persisting, linear, 5-25 cm long, 1.5-4.5 mm broad, obscurely emarginate at apex. Inflorescences single flowers or more commonly few-flowered fascicles or abbreviated, few-flowered racemes, borne at apex of stems; flowers white, 3.5-4.5 mm long; sepals 3-4.5 mm long, l-2 mm wide; petals as long as sepals, 0.5-1 mm wide; lip 3.5-5 mm long, 2-3.5 mm wide, entire or obscurely trilobate; column narrowly winged. Fruits oblong-elliptic, ca 1 cm long (including the long narrowly tapered base), ca 2 mm wide. Croat 8079. Common in the forest, usually high in trees. Flowers in the early dry season (December to March), especially in January and February. The fruits mature in the middle to late dry season. Confused with S. longicaulis, which is usually a much smaller plant bearing mostly solitary flowers.
