Macrostylis cassiopoides (Turcz.) I.Williams

Shrubs up to 1.5 m tall, erect, slender, single-stemmed at base with a long tap root. Branches erect, slender, becoming leafless, glabrous with a finely roughened grey bark. Branchlets numerous, erect, very slender, dichotomous, glabrous, well clothed with leaves. Leaves up to 7 mm long on healthy young plants, otherwise 3-5 mm long, 1.2-1.3 mm broad, lanceolate, sub-acute with a blunt point, glabrous, adpressed, erect, longer than the internodes, imbricate on new shoots, sessile-decurrent, alternate; adaxial surface concave, waxy; abaxial surface convex with scattered gland dots, sub-scabrid with minute white glands, margins narrowly cartilagenous, sparsely ciliolate towards the base. Inflorescence terminal, 1-5 aggregate, sessile. Bract 1.7 mm long, 1.2 mm broad, oblong, obtuse with a blunt reddened tip; margins broadly translucent, densely ciliolate midrib thickened, glabrous, gland-dotted; adaxial surface concave, pubescent in the upper half towards the middle. Bracteoles two, 1.8-2.0 mm long, 1 mm broad, elliptic, narrowed at the base, obtuse; midrib thickened, glabrous, gland dotted with a blunt tip; margins broadly translucent, densely ciliolate; adaxial surface concave, sparsely pubescent in the upper half towards the middle, calyx lobes five, 2 mm long, 1.8 mm broad, orbicular; margins broadly translucent ciliolate; abaxial surface glabrous with the midrib somewhat reddened, gland dotted; adaxial surface concave, densely pubescent towards the centre in upper two thirds. Petals five, 4 mm long overall, white; limb 1.4 mm diam., orbicular, margin irregular in outline; claw 2.6 mm long, 1.1 mm broad, densely bearded mainly down the midrib, crisped ciliate above. Staminodes five, 0.6-0.7 mm long, glabrous. Filaments five, becoming 3 mm long, glabrous. Anthers 1.1 mm long, 0.7 mm broad, reddened; apical gland 0.3 mm long, short-stipitate. Pollen 60 µ long, 25-27 µ, broad, elliptic or oblong. Disc closes over the ovary clasping the style, smooth, green, exudes nectar from pores on the domed surface. Stigma 0.4 mm diam., capitate, green. Style 0.4 mm diam. at first, becoming 3.5 mm long, exceeding the beards of the petals, glabrous, erect, persisting. Ovary 0.8 mm long, 0.7 mm diam., tri-carpellate, glabrous. Fruit 3 or rarely 4-carpellate, 8-8.5 mm long, brownish-red, pitted with gland dots, horns very short, erect, emarginate. Seed 5.5 mm long including the white aril, 1.8 mm broad, black, shining.
