Anaphyllum

HABIT: evergreen herbs, clump- or colony-forming, rhizome creeping. LEAVES: solitary to few. PETIOLE: smooth to tuberculate, geniculate apically, sheath short. BLADE: sagittate-hastate to pedatifid when juvenile, trisect at maturity, anterior division remotely pinnatisect with ± oblong-lanceolate, acute lobes, the upper ones decurrent, posterior divisions either ± oblong-lanceolate or deeply divided into 3 coherent segments, rachis geniculate at insertion of anterior and posterior divisions; basal ribs well-developed, primary lateral veins of ultimate lobes pinnate, running into marginal vein, higher order venation reticulate. INFLORESCENCE: solitary. PEDUNCLE: very long and slender, similar in colour and texture to petiole. SPATHE: membranous to coriaceous, marcescent, either convolute basally and becoming spirally twisted and long-acuminate apically, or oblong-ovate, ± flat and fully expanded. SPADIX: cylindric, much shorter than spathe, stipitate or sessile, flowering sequence basipetal. FLOWERS: bisexual, perigoniate, tepals 3–4, fornicate. STAMENS: 3–5, free, filaments fairly wide, connective slender, thecae ellipsoid, dehiscing by short, apical, pore-like slit. POLLEN: monosulcate, ellipsoid, medium-sized (mean 29 µm., range 25–33 µm.), exine foveolate to reticulate, sometimes with elevated psilate regions, apertural exine psilate. GYNOECIUM: ovary ovoid, 1-locular, ovule 1, hemianatropous, funicle short, placenta parietal on single intrusive septum, stylar region thick, attenuate, stigma subcapitate, exuding droplet at anthesis. BERRY: ovoid, smooth, red. SEED: ovoid, funicle slender, testa membranaceous, smooth, embryo stout, straight, endosperm absent.
