Conservation
Critically endangered (CR) using the criteria set out by IUCN (2001): B2ab (i,ii,iii). Presents a distribution restricted to the type locality, the only known collection site. Additionally, this habitat has been subject to an accelerating urbanisation and the forests are being substituted by banana plantations in some areas, whereas in others, trees are selectively removed for construction, carpentry or firewood. Effective conservation measures are not securely established and ecological data for the species are lacking.
Distribution
Known only from the margin of the Saracuruna dam, belonging to the Brazilian Petroleum Corporation — PETROBRAS.
Ecology
Atlantic forest, c. 100 m alt. Dense population at the humid and most protected edge of the very disturbed forest, which has been suffering selective cuttings for housing and firewood.
Morphology General Habit
Caulescent or rarely rosulate herb, 0.5 – 1 m high, bearing 3 – 19 basal leaves and generally one cauline leaf, rarely absent
Morphology Leaves
Leaves with a chartaceous, dark green, and densely puberulous sheath; petiole green, glabrous or sparsely pilose; pulvinus elliptic in cross-section, green, glabrous or sparsely pilose with a row of trichomes adaxially; blade narrowly-oblong to narrowly-lanceolate, base acute, apex acuminate, membranaceous, adaxial surface sparkling green, glabrous, abaxial surface light green, glabrous; midrib U-shaped basally, olive-green Cauline leaves with sheath 6 – 11 × 1.2 – 2.2 cm; petiole 3.5 – 16.5 cm; pulvinus 1.5 – 4.5 cm long; blade 27 – 48 × 4.5 – 7.5 cm Basal leaves with sheath 15 – 35 × 0.7 – 2 cm; petiole 16 – 43 cm long; pulvinus 1 – 4.2 cm long; blade 22 – 50 × 3.5 – 7.5 cm
Morphology Leaves Cataphylls
Cataphylls 13 – 51 × 0.8 – 1.6 cm, 1 – 3 per shoot, narrowly oblong to oblong-lanceolate, apex acute, papyraceous, green, puberulous to tomentose

Morphology Reproductive morphology Flowers Corolla
Corolla tube 13 – 15 mm long, white; lobes 10 – 12 × c. 3 mm, elliptic, apex rounded, white
Morphology Reproductive morphology Flowers Gynoecium Style
Style 5 – 6 mm long, straight or slightly curved, white; stigma white; ovary c. 1.5 × 1 mm, smooth, white
Morphology Reproductive morphology Fruits
Capsule not seen.
Morphology Reproductive morphology Inflorescences
Inflorescence simple, 32 – 57 × 22 – 24 mm, ellipsoid, one per shoot, subtended by a solitary leaf or occasionally terminal on a lateral leafy shoot; peduncle 2.4 – 6.5 cm long when subtended by cauline leaves or rarely c. 30 cm long when terminal, green, tomentose; bracts 18 – 23 × 14 – 17 mm, spirally arranged, 15 – 35, appearing to be in 5 – 10 horizontal series, imbricate, broadly ovate, apex acute, straight, membranaceous, light green, without markings, densely puberulous with a ciliate margin, permanently intact; prophyll bicarinate 18 – 19 × 5 – 6 mm, elliptic, apex acuminate, membranaceous, green-hyaline, densely puberulous with a ciliate margin, 3 – 4 mm carina to carina; interphyll 15 – 17 × 5 – 6 mm, oblong to ovate, apex rounded or emarginate, membranaceous, white-hyaline, densely puberulous with a ciliate margin; bracteoles 15 – 17 × c. 1 mm, 1 – 2 per cymule, linear-elliptic, apex acute, carinate, membranaceous, white, glabrous
Note
Calathea dryadica, according to the concept of Schumann (1902), belongs to Calathea subgen. Pseudophrynium Körn. series Scapifoliae (Eichler ex Petersen) K. Schum. based on the inflorescence being subtended by a cauline leaf. The specific epithet is based upon the phytogeographic areas recognised by Martius (1906) and refers to the wood nymph from the Greek druas and the Latin dryas. The new species resembles Calathea prolifera (Vell.) J. M. A. Braga by the similar growth habitat and shape of leaves. C. prolifera can be distinguished by the glabrous leaf sheath, inconspicuously nerved blade, bracts obovate with a rounded apex, hirsute and not ciliate, prophyll bicarinate 15 – 20 × 10 – 12 mm, interphyll 18 – 19 × 7 – 8 mm, elliptic and flowers with corolla lobes 14 – 15 mm long (Table 1).
