Bahia: Abaíra, distrito de Catolés, sítio Palmeiras, Serra do Porco Gordo, 13°23'S 41°46'W, 25.IV.1992, fl., Ganev 206 (SPF [SPF88316]!; iso-: HUEFS-10649!, US [US00590762]!). Species with habit very similar to Sinningia harleyi Wiehler & Chautems, but differing by the presence of a short peduncle at the base of the cymes (0.4–0.5 cm long) and by having purple, tubular-campanulate corollas (vs. peduncle absent and bright red, tubular corollas in S. harleyi). Herb 20–60 cm tall, arising from perennial, irregularlyshaped tuber, 1–4 cm in diam., saxicolous; stems 3–5 mm in diam., usually unbranched, greenish to vinaceous, pubescent with glandulous trichomes, internodes 1.5–8 cm long. Leaves 4–9 pairs, decussate, equal or slightly anisophyllous; petiole 1.5–3 cm long, green to reddish, pubescent with glandulous trichomes; blade 2.5 –6.5(–11) × 1.8– 4(–7) cm, ovate, apex acute, base rounded to subcordate, margin distinctly crenate to nearly dentate, membranaceous, green and puberulous with glandular trichomes above, paler and puberulous with glandular trichomes between the nerves, but pubescent on the nerves beneath, 6–9 pairs of lateral veins. Inflorescence frondose, composed of cymes reduced to 1 (rarely 2) flowers, arranged in opposite pairs in the apical 3–9 leaf axils. Flowers borne on a short peduncle, 0.4–0.5 cm long, with 2 bracts 0.4 × 0.2 cm at the base of a single, rarely 2, ascending pedicel, 1.3–1.8 cm long. Calyx campanulate, fused at base along 2–3 mm, lobes 7–9 mm long, lanceolate, c. 3 mm wide at base, margin entire, green, glandular pubescent. Corolla yellowish during bud stage, tubular-campanulate at anthesis, erect in calyx (i.e. aligned with axis of calyx), 3.5–4 cm long, 0.4– 0.5 cm in diam. at base, tube 1–1.2 cm wide, dorsal side slightly arcuate, ventral side gradually expanding, light purple for most part, dark purple on the lobes inside, pubescent, lobes subequal, entire, 5– 6 × 8 –9 mm, patent to ... |
