General Description

STEM: ± erect, often forming extensive scrambling branching system up to 4m long, or epiphytic. plants hanging down with the shoot tips turning upwards, (1.2-) 1.5-3 cm thick; adventitious roots up to l.5 cm diam. when mature, becoming woody, black and tuberculate, differentiated into feeding and clasping roots, the latter forming extensive support system in epiphytic plants; internodes 0.1-1.6 cm long, green when young, becoming chestnut or coppery brown and eventually grey with age; prophyll scars 0.1-0.2(-0.6) cm long, usually shorter than internodes: intravaginal squamules short, 1-3.5(-4) mm long, 1-1.5(-2) mm wide, ± elliptic in section, not strongly flattened, jutting out and ± recurved, sharply-pointed, usually arranged in rows near apex of each internode just below prophyll scar but also occurring in middle of internode; foliage leaf scars suborbicular to elliptic, sometimes oblique, usually longer than broad, 1.1-2.8 cm long, 0.9-1.5(-2) cm wide. LEAF: prophyll 17-30 cm long; petiole 22-46 cm long, 0.3-0.5(-0.8) cm diam. at apex, broadly sulcate adaxially with angled margins, sometimes with central ridges, sheath 5-11 cm long; leaf blade sagittate, margins repand, overall length 23-40(-50) cm long, overall width 15-24(-35) cm wide, upper surface clark ± glossy green with paler main veins, lower surface paler with whitish-green sometimes pink-tinged primary lateral veins; anterior division 15.5-26(-33) cm long, 13.5-24(-27.5) cm wide, apex usually acute-acuminate, sometimes subacute-cuspidate, primary lateral veins 3-5 pcr side, arising at an angle of (30-)40-85º near base, cross veinlets of finest parallel veins usually very distinct in both dried and fresh material; posterior divisions retrose. introrsc or sometimes slightly extrorse, 7.5-14 cm long, 0.3 x overall bladc length, 7.5-1.3 cn wide, basal ribs denuded proximally on basiscopic side for (0.8-)l.5-4 cm, tip acute to subacute and rounded at extremity, primary acroscopic veins (1-)2-3(-5), primary basiscopic veins 0-3, weaker, basiscopic lamina areas well-developed, usually not overlapping. INFLORESCENCE: peduncle shorter than spathe, 3-7(-11) cm long, 0.5-0.8 cm diam. at apex; spathe 12-18 cm long, 2-3.5 cm diam. at middle, green on outer surface, uniformely white within, decurrent for 4-8 cm; spadix 10-17 cm long, fertile male zone 1.5-3 cm long, 0.8-1.7 cm diam., sterile male zone 3.5-7.5 cm long, 1-2.2 cm diam., ± cylindric, female zone 1.6-2 cm long or more (dorsally), ca. 1.3-2 cm diam., con- spicuously adnate to spathe for up to 5 cm. FLOWERS: stamens 4 per flower, 3- 5 mm long, 0.6-1 mm wide at apex, tapering to base; staminodes 5- 6 per fllower, 3-5.5 mm long, 0.9-1.3(-1.5) mm diam. at apex, prisrnatic, truncate at apex, tapering to base; gynoeciurn 3 - 4 mm long, ovary ± cylindric, 2-3 mm diam., raphide cells common in upper walls of locules, locules 4-6(-12) per ovary, ovules (1-)2-3(-4) per locule, inserted on basal half of axis, style body short, ± as wide as ovary, with dense axial raphide con- centration around stylar canals, compitum not penetrating ovary, central dome lacking or present but weakly developed, stylar canals entering locules subapically or almost halfway down, stigma at anthesis not seen. INFRUCTESCENCE: no ripe fertile berries seen, galled berries yellow-orange at maturity.

Habitat

Terrestrial in coastal restinga scrub on sandy soils and hemiepiphytic in coastal rainforest and tall restinga forest.

Distribution

East and South Brazil.

Uses

In Santa Catarina the plant is called 'cipó preto' (black liane) and was employed as cordage for boat-building, among other uses, due to its resistance to decomposition (Reitz 1958).
