Leucoptera oppositifolia B.Nord.

Erect or ascending shrublets 2-6 dm high, moderately to richly branched. Leaves opposite (rarely some subopposite or alternate), rather laxly set (internodes mostly 0.5-1 cm, sometime up to 2 cm long), linear-oblanceolate, 0.5-2(-2.5) cm long, 1-2(-3) mm thick, somewhat narrowed towards the base, usually entire, seldom 3(-4)-lobed below the middle, somewhat flattened, leathery, greyish green, obtuse. Peduncles erect, often flexuous when young, 5-18 cm long, 0.6-1 mm thick, faintly striate. Involucre 0.6-1.3 cm wide. Outer (visible) involucral bracts ca 12, broadly ovate to elliptic-oblong, with 5-7 faint resiniferous veins, herbaceous, with brownish membranous margins and obtuse-rounded tips. Innermost involucral bracts 4-5, shorter than the largest outer ones, ± oblong, truncate-emarginate, submembranous. Receptacle convex-hemispherical, nude. Ray-florets ca 8(6-11). Tube 1-1.3 mm long, somewhat compressed, glandular in the upper part. Lamina oblong-obovate-elliptic-oblong, 3-7 mm long, 2.5-3.5 mm wide, 5-7-veined, apically shallowly 3-lobed, white, becoming pink-reddish and reflexed when old. Style branches 0.3-0.5 mm long, oblong, slightly emarginate, with a central resin excretion. Disc-florets 25-50. Corolla 2.4-2.8 mm long. Tube 1-1.3 mm long, broadly cylindrical, glandular-hirsute in the upper part. Limb campanulate, ca 1.5 mm long; lobes deltoid-ovate, 0.5-0.7 mm long, with a small resin dot near the tip (rarely 2-3 dots). Anthers ca 1 mm long incl. the ovate-triangular obtuse-subacute appendage. Style branches ca 0.5 mm long, with a central resin excretion, truncate. Pollen grains ca 37x 39 ? (spines included). Total number of spines in one pollen grain ca 38. Exine as in L. subcarnosa.
