Euchaetis vallis-simiae I.Williams

Shrubs to 1.20 m, erect, single-stemmed at base, not forming a dense bush. Branches erect, straight, puberulous, somewhat reddened, slightly roughened by leaf scars, arising more or less in clusters. Branchlets fairly short, erect, puberulous, well clothed with leaves but not hidden, light green at first, tending to arise in clusters at all heights in the plant. Leaves 5-8 mm long including the petiole 1 mm long, 2.5-2.8 mm broad, elliptic, conspicuously gibbous behind the apex, at base adpressed erect, sub-imbricate, alternate, scabro-tomentose on all sides and margins with erect tapering hairs, midrib prominent with minute gland dots to either side. Inflorescence terminal, 1-4 nate; calyx puberulous; flowers 7 mm diam., sessile, white. Bract 4.8-5 mm long, 2-2.2 mm broad, sub-ovoid, scabro-tomentose on all sides, minutely gland-dotted, petiolate, apex reddened and gibbous on the outside, margins ciliate, midrib prominent. Bracteoles two, 4.5 mm long, 1-1.2 mm broad, oblanceolate, obtuse, scabro-tomentose on both sides, strongly ciliate, minutely gland-dotted, apex gibbous on the outside, margins narrowly translucent, midrib prominent. Calyx lobes five, 3.1-3.3 mm long, 2-2.2 mm broad, sub-quadrangular, scabro-tomentose on both surfaces, ciliate, margins narrowly translucent, apex gibbous on the outside. Petals five, 5.6 mm long, soon falling away; limb 2.1 mm broad, ovate, spreading, abaxial surface puberulous, apex sub-emarginate with a few cilia; claw 1.4 mm broad, narrowing to 0.25 mm at the base, strongly transversely bearded with ciliate margins above. Staminodes five, 0.15 mm long, vestigial, a minute blunt point on the outer rim of the disc. Filaments five, becoming 1.6 mm long, glabrous, acicular. Anthers five, before anthesis 1.2 mm long, 1 mm broad, pale yellow, with a minute globose apical gland. Pollen 41 µ long, 30 µ broad, ellipsoid. Disc green, fleshy, exudes nectar, fairly level on top, closes somewhat over the ovary. Stigma 0.7 mm diam., capitate, depressed globose, green. Style becoming 1.5 mm long, erect, glabrous, persisting. Ovary 5-carpellate, 0.7 mm long, 1.0 mm diam., apices of lobes globose and densely pubescent. Fruit 5-carpellate, 9 mm long, 6 mm diam., scabro-tomentose, sessile, closely imbricated at the base by the persistent calyx lobes which have a white waxy exudate on the inside; horns 2.5 mm long, sub-erect, obtuse, dark green or reddened. Seed 5.5-6.6 mm long, 2-2.5 mm broad, black, shining with a black and white aril.
