We describe and illustrate a new species of Masdevallia from the Andean-Amazonian foothills Caquetá, Colombia. leonor-baeziana belongs to subsect. Saltatrices, within M. constricta group. It is most similar constricta, but it can be distinguished by shorter sepals sepaline tails that do not surpass tube length, shorter, sigmoid-ovate lip. proposed categorizing as Critically Endangered (CR) base...

Two new species of Pleurothallis subsection Macrophyllae-Fasciculatae are described and illustrated. Both were found in the central Andes Colombia department Tolima. The two compared discussed with applanata, ariana-dayanae, paquishae, scabrilinguis, which morphologically closest species. differ from their congeners mainly by lip morphology. franciana is distinguished having an oblong-lanceolat...

Coelogyne magnifica (Orchidaceae), a new species from Putao, Kachin State, Myanmar, is described and illustrated. It belongs to Coelogyne section Ocellatae Pfitzer & Kraenzl. and it is morphologically similar to Coelogyne corymbosa and C. taronensis, but can be distinguished from these species by its larger flowers, lanceolate sepals and petals, a narrowly ovate lip, which has two bright yellow...

Selaginella guihaiasp. nov. (Selaginellaceae), a new species of spikemoss from southern China and northern Vietnam around the Gulf of Tonkin (Beibu Gulf), is described and illustrated. Morphological and molecular comparisons of the new species with other similar species (S. doederleinii, S. ornata and S. trachyphylla) are provided. The morphological and molecular evidence clearly indicates S. g...

M onarde/la stebbinsii (Lamiaceae ), a new species from the northern Sierra Nevada of Plumas County, California, is described and illustrated. Characterized by ovate leaves, multiple verticillasters per infiorascence, a matlike habit, reddish papery bracts, and purplish-red leaves with a soft white pubescence, the species is not closely related to any other species of the genus. The new species...

Two new ascomycetes, Boerlagiomyces costaricensis (Pleosporales) and Scopinella musciformis (Sordariales sensu lato), from litter samples collected in rainforests of Costa Rica, are described and illustrated. Boerlagiomyces costaricensis has globose, ostiolate ascomata covered by numerous setae-like hairs; cylindrical, fissitunicate asci without apical structures; and large, fusiform, muriform,...

Fruits represent an important part of the human diet and show extensive variation in size and shape between and within cultivated species. The genetic basis of such variation has been studied most extensively in tomato, where currently six quantitative trait loci (QTLs) involving these traits have been fine-mapped and the genes underlying the QTLs identified. The genes responsible for the clone...

Hellenia speciosa (J. Koenig) S.D.Dutta, a clonally propagated plant, widely known as crepe ginger, is an important medicinal plant of tropical Asia. It rich source diosgenin- phytosteroid sapogenin used in the commercial synthesis progesterone. Despite clonal propagation, produces substantial number viable seeds, which later become short-lived seedlings. Therefore, this research aims to compre...
