Two new species of Ophiocaryon (Sabiaceae) from South America

Ophiocaryon barnebyanum from the Serra da Neblina (Venezuelan-Brazilian border) andO. neillii from southern Ecuador are described and illustrated, and their morphological relationships with allied spcies are discussed.Ophiocaryon barnebyanum is morphologically similar toO. duckei, but it differs by its larger leaves, leaflets, petioles, petiolules, and inflorescences, the higher number of secondary veins, and the ciliate sepals.Ophiocaryon neillii is a small tree related toO. klugii but differs by its smaller leaflets, petiolules and inflorescences, fewer secondary veins, lanceolate-acuminate sepals, and orbicular staminodes. An updated key to the species ofOphiocaryon is provided.

Barringer, Kerry (Department of Botany, Field Museum of Natural History, Chicago, IL 60605). Two new species of Esterhazya (Scrophulariaceae) from Brazil. Brittonia 37: 195–198. 1985.—Esterhazya petiolata is a distinctive species with ovate, petiolate leaves, spreading brances, and broadly tubular-campanulate flowers.

Two new species of Myrtaceae (Myrteae) from northern South America

Two new species of Myrtaceae are described and illustrated. Campomanesia cucullata is a tree from Monte Alegre, Pará, in the Brazilian Amazon. It is most similar to C. lineatifolia, from which it differs by being leafless when flowering, and by having densely congested and very small flowers. Myrcianthes monteucalyptoides is a tree from Tarma, Junín, in Central Peru. It is most similar to Myrcianthes myrsinoides, but the new species differs by a combination of medium-sized, somewhat revolute, broadly-acuminate leaves, and by the solitary, pentamerous flowers with delicate pedicels.     

Two new species of Clavija (Theophrastaceae) from NW South America

Two new species of Odontocarya sect. Somphoxylon (Menispermaceae) from South America

Odontocarya monandra Barneby, resembling O. deminuta in glabrous staminate panicle, 3-merous corolla and solitary stamen, but notably different in shape and venation of leaves and larger staminate flowers, is described from Prov. Maynas, northeastern Peru; and O. septemfida Barneby, the only known member of the genus with lobed leaves, from Edo. Falcón, Venezuela.     

Two new species of the genus Pelexia (Orchidaceae, Spiranthinae) from South America

Szlachetko, D. L. 1995. Two new species of the genus Pelexia (Orchidaceae, Spiranthinae) from South America. - Nord. J. Bot. 15: 173–175. Copenhagen. ISSN 0107–055X.
Pelexia sheviakii and Pelexia collocaliae are described as new species from Ecuador and Paraguay respectively. Pelexia sheviakii differs from Pelexia bonariensis and any other species related by its lip form, which is rhomboid, has no constriction, and with basal lip thickenings produced on upper surface of claw. The most characteristic features of Pelexia collocaliae are U-shaped callus at apices of petals, erect flowers, straight lateral sepals and narrow lip with two small calli near isthmus.     

Two new species of Isospora (Apicomplexa: Eimeriidae) from passeriform birds of South America

Summary Two new species of Isospora (Apicomplexa: Eimeriidae) are described from the faeces of passeriform birds of South America. I. cyanocoracis n. sp. is described from Cyanocorax chrysops (Passeriformes: Corvidae) and I. paroariae n. sp. from Paroaria coronata (Passeriformes: Emberizidae). I. cyanocoracis oocysts are spherical or subspherical, 28.7×26.8 m (25.0–30.5×24.5–29.0), with bi-layered wall about 2.0 m thick. Micropyle and oocyst residuum are absent; large polar granule present. Sporocysts are ovoid, 19.3×11.4 m (17.0–21.0×10.5–12.2), with smooth, single-layered wall about 0.8 m thick. Stieda and substiedal bodies and sporocyst residuum are present. Sporozoites 12.2×4.2 m (10.5–15.0×3.5–4.5), possess spherical anterior and posterior refractile bodies. I. paroariae oocysts are spherical or subspherical, 22.3×21.4 m (19.5–25.5×18.5–24.0), and have bi-layered wall about 1.8 m thick. Micropyle, polar granule, and oocyst residuum are absent. Sporocysts ovoid, 15.2×10.0 m (14.0–16.5×8.0–11.5), possess smooth, single-layered wall about 0.7 m thick. Stieda and substiedal bodies and sporocyst residuum are present. Sporozoites elongate, 11.3×3.4 m (10.0–13.5×3.2–4.0), have single, large, posterior refractile body. ac]19840712
