Type:— BRAZIL. Espírito Santo: Águia Branca, propriedade de Ciro Ferreira, 18º 58’40.5”S, 40º 39’56.1”W, 250 m, 27 April 2006, V. Demuner, L.F.S. Magnago, T. Cruz& E. Bausen2270( holotypeMBML!, isotype HB not seen). Plants rupicolous or terrestrial, stoloniferous, stems elongate, 12–15 × 1.8 cm. Leaves slightly arching. Leaf sheaths green, ovate, 3.6 × 2–2.5 cm, lepidote at base, margins serrate, prickles ca 3 mmlong. Leaf blades coriaceous, canaliculate, green, internal one reddish, narrowly triangular, 30–55 × 1.5–1.7 cm, attenuate, lepidote, glabrous and bright at base, margins serrate, prickles straight or retrorse, 2–3.5 mmlong, apices acute. Inflorescences sessile, compound, many–flowered. Primary bracts subcoriaceous, green or red, very narrowly triangular, 3.2–12.7 × 1.8 cm, margins serrate, apices acuminate. Floral bracts subcoriaceous, green, asymmetrical, carinate, narrow triangular, ca 1.6 × 0.8 cm, lanate, margins serrate, apices acuminate. Sepals green, asymmetrical, carinate, triangular-lanceolate, 1.6–1.8 × 0.4 cm, densely lepidote, margins entire, apices acuminate. Petals green with white margins, spatulate, 1.7–1.8 × 0.5–0.6 cm, glabrous, obtuse, apices cucullate. Petal appendages cupuliform, lacerate, ca 3 mmfrom base. Callosities conspicuous, ca 2.5 mmlong, apices not apiculate. Ovaries trigonous. Epigenous tubes absent. Ovules numerous. Fruits and seeds not seen.
Distribution and habitat:— Orthophytum pseudovagansis only known from Águia Branca county in the state of Espírito Santo, where it grows on rocky outcrops in the Atlantic rain forests at ca 250 melevation. IUCN conservation status:—DD. Orthophytum pseudovagansstill lacks sufficient distribution data, because it was discovered only recently and is currently known only from the typematerial.
Comments:—According to Leme & Kollmann (2007), O. pseudovagansforms the ' vaganssubcomplex' together with O. vagans Foster (1960: 59)and O. zanonii Leme (2004b: 72). Long stems and obtuse–cucullate petal apices characterize this group of species. Orthophytum pseudovagansdiffers from O. vagansmainly by its compound (vs. simple) inflorescences. It differs from O. zanoniiby longer leaf blades ( 30–55 cmvs. 12–14.6), which are glabrous, bright green–spotted and red at the base (vs. lepidote and concolorous green).
