jointed, 1–4(–5) mm, puberulent, stipitate-glandular; bracts lanceolate-ovate, 1.3–3 mm, puberulent, stipitate-glandular. |
Flowers | hypanthium greenish white to white, tubular, (2.3–)4–6 mm, softly hispid abaxially, glabrous adaxially; sepals not overlapping, spreading, greenish white to white, lanceolate, (2.5–)3.5–7 mm; petals nearly connivent, erect, cream with red margins, whitish or pinkish, oblanceolate to spatulate-obovate, not conspicuously revolute or inrolled, 2–4.4 mm; nectary disc not prominent; stamens nearly as long as petals; filaments linear, 1.3–3 mm, glabrous; anthers cream to violet, oval, 0.5–1.6 mm, apex with cup-shaped depression; ovary pubescence not bristly, hairs soft; styles connate nearly to stigmas, 0.7–1 mm, glabrous. |
hypanthium pinkish to orangish, saucer-shaped, 0.5–1.5 mm, pubescent and stipitate-glandular abaxially, glabrous adaxially; sepals separated, spreading, green to yellowish, pink, red, orange, or white, sometimes with pale yellow, scarious margins, broadly ovate to obovate, 2.5–4 mm; petals widely separated, erect, red, pinkish, or purplish, cuneate-lunate, not conspicuously revolute or inrolled, 0.9–1.5 mm; nectary disc yellowish, pinkish, or red, flat, 5-angled, covering most of ovary; stamens as long as petals; filaments linear, (0.5–)0.9–1.6 mm, glabrous; anthers yellow or cream, oblate to transversely elliptic, 0.5–0.8 mm, broader than long, apex notched; ovary sparsely to thickly, usually purplish glandular-bristly; styles connate ca. 4/5 their lengths, 1.1–1.8 mm, glabrous. |
