Satyria pterocalyx Pedraza

Epiphytic shrub, lianoid; stems brown-grey, terete, glabrous, bark smooth; twigs subterete, smooth, glabrate, the hairs inconspicuous (< 0.1 mm long), unicellular and eglandular (all indumentum composed of this type of hairs except when indicated). Axillary buds compressed; prophylls 2, valvate, lanceolate, conspicuous, 3.6–4.1 mm long, margin eciliate, apex acuminate, glabrous. Leaves alternate; petiole terete, not pulvinate, 6–8 mm long, glabrescent; lamina coriaceous, elliptic, often slightly asymmetric with the apex slanted to one side, 14–18 × 5.8–7.3 cm, base obtuse or cuneate, margin entire and eciliate, apex long acuminate (acumen 1.8–2.8 cm long), adaxially glabrous, abaxially glabrate, the hairs inconspicuous, (< 0.1 mm long), multicellular and eglandular; laminar glands absent; venation plinerved (acrodromous), suprabasal, with 3–4 visible orders in dry specimens, prominent lateral veins 2(–3) per side, subopposite, concentrated in the basal third, ascending, brochidodromous, midvein and secondaries adaxially impressed and abaxially raised. Inflorescence a axillary, solitary, raceme with at least 2 flowers, cauliflorus; inflorescence bracts, floral bract, and bracteoles alike, persistent, chartaceous, ovate, 1–1.6 × 0.5–1 mm, margin entire and ciliolate, the hairs inconspicuous, caducous and eglandular, apex acute to acuminate, glabrous on both sides, venation obscure; rachis green, 5–12 mm long, glabrous; pedicel orange, articulate with calyx, 2.6–3 cm long, basally less than half the diameter of apex (in vivo 1.5 mm vs. 4.5 mm, respectively), glabrescent, with inconspicuous warts basally (not evident in vivo); bracteoles 2, basal, supopposite to alternate. Flowers 5-merous, actinomorphic, diplostemonous. Calyx light green, oblate (more or less campanulate when dry), 3.8–5.6(–7.7) mm long (6.2–6.5 mm in vivo), 5-winged, the wings alternating with lobes, minutely puberulous; tube oblate, 3–3.2(–5.2) mm long (3.5–4.1 mm in vivo), the base conspicuously lobed, each facet of the calyx demarked by the wings contains two basal lobes that together look like an inverted m; limb more or less erect, 1.6–2(–2.5) mm long (2.4–3.3 mm in vivo); lobes deltate, 0.8–1 × 3–3.5 mm long (0.5–1.2 × 4–6 mm in vivo), margin entire, eglandular, and eciliate, apex obtuse; sinuses obtuse (U-shaped) to almost flat; aestivation unknown. Corolla red-orange with the tube and lobes green-whitish, fleshy, bistratose, obconic and noticeably constricted at the throat which is elongated into a tube (ca. 8 mm long), terete, 2.8–3(–4) cm long, 1.2–1.3 cm diam., 2.7–3 mm wide at throat (4 mm in vivo), inconspicuously puberulous without with a combination of hairs minute (< 0.5 mm long), eglandular and unicellular, along with a few hairs eglandular and multicellular, glabrous within; lobes deltate, 1.1 × 1.2–1.5 mm (lanceolate, 4.3 × 2 mm in vivo), apex acute, not strongly reflexed at maturity; aestivation unknown. Stamens 10 (all measurements in vivo), dimorphic, staminal cycles with different anther lengths and dehiscence orientation, included, not adherent to corolla. Long stamens 9.8–10.8 mm long; filaments connate at base, straight, 3–4 mm long, glabrate, the hairs inconspicuous and eglandular, the marginal ones unicellular, the abaxial ones multicellular, very scarce and distally concentrated, adaxial side glabrous; anthers 8.6–10.1 mm long, narrowing at base and widening at apex, without a clear distinction between tubules and thecae; thecae 5.9–7.1 mm long, without basal appendage, papillate at base, smooth at apex; tubules 2, free, pointing upwards, 2.5–3 mm long, smooth, dehiscing by latrorse elliptical slits 2.2–2.5 mm long, abaxial side and margin ornamented with irregular epidermal projections. Short stamens 8.3–9.5 mm long, same shapes, indumentum and features as long stamens except when indicated; filaments 3–3.5 mm long; anthers 7.5–9.4 mm long; thecae 5.2–6.4 mm long; tubules 2.3–3 mm long, dehiscing by introrse elliptical slits 2.2–2.5 mm long. Nectary pulvinate, not too prominent, glabrous; style 2.8–3.2 cm long, included; stigma discoid. Berry unknown.
