General Description

Appressed-climbing epiphyte; stems short, rooting at the nodes; internodes 3–11 cm long, 0.5–2 cm diam., becoming brown; cataphylls green, 31–50 cm long, unribbed, weathering ± intact (persistent, at least in part, to 9 internodes back), quickly drying dark brown, ultimately deciduous. Leaves pendent on adult plants, on adult plants, petiole firm, terete, sulcate at base,  (9–)14–56 cm long, (2–)3–8 mm diam. near base, (1–)3–5 mm near apex, thinly winged for 3–9 cm, drying dark brown; blade ovate-lanceolate to elliptic, subcordate or rounded at base, (19–)34–97 cm long, (3–)6–19 cm wide, averaging 53 × 11 cm, 3.9–6 × longer than wide, 1.5–2.4 × longer than petiole, cuspidate at apex, subcordate at base, thinly coriaceous, dark green and concolorous, matte above, glossy below, somewhat quilted in age, drying dark brown above, lighter brown below; midrib convex above and whitish, bluntly triangular below; primary lateral veins 12–19 pairs, arising at 70–75º angle, quilted-sunken above, convex below; basal veins 1–3 pairs, all free to the base; minor veins obscurely visible, running closely parallel to each other and to the primary lateral veins. Inflorescences 1–2 per axil; prophylls deciduous intact, 19–22 cm long; peduncle short, c. 5 cm long, 1.3 cm diam. at apex; spathe 16–17 cm long, tube c. 6 cm long, 2 × 3 cm wide, lacking any obvious resin canals inside, scarcely or not at all constricted above the tube, outside light green and semiglossy with a purplish tinge at the base, inside weakly glossy and dark red in tube, gradually paler and glossier above tube, more nearly red-violet on middle of blade, with the upper margins and apex white; spadix 14– 15 cm long; staminate portion white, 8.8 cm long, 1.4 × 1.2 cm wide on fertile staminate portion, sterile staminate portion c. 1.5 cm long, 1.3–1.5 cm wide; pistillate portion green, 5.2 cm long in front, 3.8 cm long in the rear, 1.3–1.5 cm wide at base, 1.2 cm × 1.4 cm diam.  midway; pistils 2–2.2 mm long, 3.5–4 mm diam., style 0.8–1.2 mm wide, donut-shaped (torus) with a central depression, locules 7, ovules axile, 10–12 per locule, c. 0.1 mm long, borne in two rows and contained within and evenly spaced along the axis of translucent envelope which is 0.8–1. mm long, 0.2–0.3 mm wide.

Diagnostic Description

The species is a member of Philodendron subg. Philodendron sect. Philodendron subsect. Canniphyllum. The ovules are arranged axially and number up to at least 10 per locule, so it appears certainly to be a member of P. sect. Philodendron. It is characterised by its short stems and pendent narrow blades, which are matte and become undulated in age. As an adult plant the species is one of the most attractive species in the genus.


Philodendron patriciae is seemingly closest to P. rhodospathiphyllum Croat & D. C. Bay from Valle Department in the Bajo Calima region and at Yatacué in the Alto Anchicaya basin. That species differs in having  persistent cataphylls, blades that are merely rounded at the base and has spathes that are yellow-green inside.

Distribution

Endemic to Colombia known at present only in Chocó Department in the area of Tutunendo and in the type locality near the Río Atrato on the road to Lloró.
