  • Description

    Species Description - Herb, to 20 (?) cm tall; stem for the greater part supraterranean, erect or ascending, 2-3.5 mm thick, puberulous with uncinate hairs; internodes to 0.8 cm long. Leaves in spirals, spaced; lamina oblong to subovate, 7-18 × 2-7.5 cm, chartaceous; apex acuminate to subacute; base cordate; margin crenate-dentate; upper surface sparsely hispidulous, scabridulous; lower surface hispidulous to puberulous with uncinate hairs on the main veins; lateral veins 7-10 pairs, loop-connected; tertiary venation reticulate to subscalariform; petiole 2.5-9.5 cm long, (minutely) puberulous to (subhirtellous) with retrorse straight and curved hairs; stipules ovate to subcordiform, 0.3-0.6 cm long, plurinervate, subacuminate, sparsely hispidulous. Inflorescences green with a red margin; peduncle ca. 3 cm long, minutely puberulous to hispidulous; receptacle centrally attached, discoid, orbicular in outline, ca. 0.8 cm diam., the outside minutely puberulous to hispidulous, ± distinctly ribbed when dry, margin forming a subcrenate rim, the fringe narrow; bracts ca. 10-12 (almost) in a single submarginal row, radiating, subspathulate, (0.5-)2-3 mm long, hispidulous; staminate flowers among the pistillate ones; tepals 2; stamens 2; filaments almost as long as the perianth; stigmas equal in length, ca. 0.3 mm long. Endocarp body not seen.

  • Discussion

    Dorstenia albertii shows strong similarities to D. grazielae. It is mainly distinct in the smaller inflorescences, shorter stipules, and shorter stamens. It might merit recognition only at the subspecific level.

  • Distribution

    In eastern Brazil (Espírito Santo), only known from the type locality, a moist and shaded place.
