Encyclia inopinata (Orchidaceae, Laeliinae) a new species from Mexico
A new species of Encyclia from Mexico, Encyclia inopinata, is described and illustrated. This species is similar to Encyclia diota but it can be distinguished by its usually more robust plants with 2-3 leaves per pseudobulb and its flowers with longer and narrower sepals (1.8±0.1 × 0.63±0.03 cm in Encyclia inopinata versus 1.48 ±0.14 × 0.65±0.06 cm in Encyclia diota) and petals (1.7±0.05 × 0.59...
متن کاملStelis zootrophionoides (Orchidaceae: Pleurothallidinae), a New Species from Mexico
BACKGROUND Stelis (Orchidaceae) encompasses approximately 1100 species of epiphytic orchids distributed throughout the Neotropics, with the highest diversity in Andean South America. Sixty-two species were recorded previously in Mexico. METHODS We formally describe here Stelis zootrophionoides as a new species from Chiapas, Mexico. To determine its systematic position, we conducted a morpholo...
متن کاملA new species of Amphitecna (Bignoniaceae) endemic to Chiapas, Mexico
Amphitecna loreae Ortiz-Rodr. & Burelo, sp. nov. (Bignoniaceae), a new species endemic to the karst rainforest in southern Mexico, is described and illustrated. The new species differs from the other species of Amphitecna by the combination of cauliflorous inflorescences, larger flowers, buds rounded at apex, and globose-ellipsoid rather than acuminate fruits. A key to the Mexican species of Am...

متن کاملWithin-population genetic structure and clonal diversity of a threatened endemic metallophyte, Viola calaminaria (Violaceae).
We studied the within-population genetic structure and the clonality extent of Viola calaminaria, a rare endemic species of calamine soils, by means of RAPD markers in two populations (one recent and one ancient) with expected harsh and heterogeneous heavy-metal stress. At a very local scale (0.2-3 m), clonal propagation was detected in both populations, but the levels of clonal diversity were ...
