Cranichis maldonadoana Kolan., Baranow, S. Nowak & A. Fuentes, sp. nov. Type . BOLIVIA . Bastian 937 ( holotype LPB!; isotype LPB!). Diagnosis. Species similar to C. pleioneura , but distinguished by 1-veined sepals, lanceolate-ovate petals that are sparsely ciliate in the lower part and by subsessile, suborbicular-obovate lip with apiculate apex. Plants 30-40 cm tall, erect. Leaf 1, basal, petiolate; petiole 11-14 cm long, narrow, canaliculate; blade 7.8-10 cm long, 4.2-6 cm wide, ovate, apex not preserved. Scape enclosed in 4-5 sheaths, glandular towards apex. Inflorescence 6-7 cm long, cylindrical, densely many-flowered . Flowers greenish-yellow, glabrous. Floral bracts 3.3 mm long, lanceolate, acuminate, glabrous. Pedicellate ovary 4.2 mm long, glabrous. Dorsal sepal 3.7 mm long, 1.5 mm wide, oblong-elliptical, obtuse, 1-veined. Petals 3.2 mm long, 1 mm wide, obliquely lanceolate-ovate, obtuse, 1-veined, ciliate on basal 2/3. Lateral sepals 4.2 mm long, 1.3 mm wide, obliquely elliptic-ovate, subacuminate, subobtuse, 1-veined. Lip 2.4 mm long, 2 mm wide, lower part concave, subsessile, suborbicular-obovate, apex apiculate; disc with 3 thickened, dendritic branching veins. Gynostemium 2.3 mm long. Fig. 12 . Figure 12.

Dedicated to Carla Maldonado, the director of Herbario Nacional de Bolivia, for her great support during our studies in Bolivia. Habitat and ecology. Terrestrial plants growing in Tucumano-Boliviano pine ( Podocarpaceae ) forest at an altitude of 2100 m. Flowers in March. Representative specimen. BOLIVIA. Tarija : Prov. Cercado, cerca Victoria, 2150 m. 3 March 1986. E. Bastian 937 (LPB!). Fig. 2B , 12 . Notes. This species resembles C. pleioneura and C. barkleyi Szlach. & Kolan., from which it differs in its lanceolate-ovate petals (vs. linear-oblanceolate to linear-ligulate), which are rather sparsely ciliate on the lower part (vs. equally ciliate or pilose along whole length). Unlike in C. pleioneura those of C. maldonadoana are 1-veined. Cranichis atrata Schltr. differs from C. maldonadoana by having ligulate-oblanceolate petals, which are ciliate along both margins (vs. lanceolate-ovate, obtuse, 1-veined, ciliate on the basal 2/3). The comparative morphology of C. maldonadoana , C. barkleyi and C. pleioneura is presented in Table 2 . Table 2. Comparative morphology of C. maldonadoana , C. barkleyi and C. pleioneura .

Specimen Bastian 937 is heterotypic. Two specimens from this collection, which are currently included in the general collection of LPB, are C. maldonadoana . Plants deposited in the boxes with the undetermined materials in the same herbarium fit the characteristic of C. badia Renz ex Kolan. & Szlach.
