A New Species

Quercus meavei is described and illustrated as a new species of section Lobatae in the Sierra Madre Oriental. It is compared to Q. albocincta, Q. acutifolia, Q. furfuracea, Q. grahamii, Q. skinneri, Q. uxoris and Q. xalapensis in the Acutifoliae group, which present a biennial pattern of maturation of fruits. Quercus meavei differs from these species in having ovoid to subspherical and glabrate acorns, leaves with a greater number of secondary veins [(12)14–19] impressed adaxially, a crispate leaf margin, long-ovoid buds with golden trichomes towards the apical scales and branchlets usually fulvo-tomentose.

Dasylirion micropterum is described as a new species from high elevations of the Sierra Madre Oriental in the Mexican state of Coahuila. It differs from known species of Dasylirion for having ascending dark green leaves, narrow inflorescences, small fruits with narrow wings and its distribution restricted to the western side of the Sierra Madre Oriental. The identity of the new species was confirmed through the sequence of matK and rbcL plastid DNA regions. GenBank sequences accessions are included. An illustration, photos and a distribution map are presented for the new species.

A New Species

Pinguicula simulans (Lentibulariaceae), a new species endemic to Sierra Madre Oriental, is described and illustrated from plants collected at Potrero Redondo, municipality of Santiago, Nuevo Léon, Mexico. Its flowers are similar to those of P. gracilis and the new species therefore belongs to Pinguicula subg. Temnoceras, sect. Microphyllum. It differs from other species in the section by the spatulate winter leaves, which are longer than wide, with a slightly recurved apex. In addition, it is distinguished by the long spatulate, ascendant or diffuse, recurved, summer leaves, which form a loose rosette, and by the calyx that has glandular pubescence on both surfaces.

A New Species

Dahlia tamaulipana (Asteraceae, Coreopsideae) a new species from Sierra Madre Oriental in Tamaulipas, Mexico, is described. The new species is morphologically similar to D. tubulata, but differs by developing stems evidently hexagonal and villous in the upper portion of the nodes and the base of the petioles, the internodes reach 3–5.5 × 1–1.5 cm, the stipels are present from the first to the third pair of leaflets, the synflorescence develops (1–)15–25 heads, the heads reach 6.5–10 cm wide across the extended rays, and clavate cypsela with crown-shaped pappus. Both species inhabit the northern portion of the Sierra Madre Oriental, however they are not sympatric and do not share ecological preferences and phenological behavior. The description of the new species is accompanied with photographs, a chromosome count, and a distributions map and a key for Dahlia in Sierra Madre Oriental.

A New Species

A new species of Magnolia from the southern Sierra Madre Oriental, Mexico, is described and illustrated, providing information about its habitat distribution, ecology, biogeography and conservation status. After 12 fieldwork expeditions near the border of the states of Hidalgo and Puebla, we have developed morphological, ecological and biogeographic data to support recognition of populations from Acaxochitlán, Hidalgo and Pahuatlán, Puebla as a distinct species of Magnolia sect. Macrophylla. A key to species of this section and a distribution map for Mexican taxa are provided. The species was assessed as critically endangered (CR).

A New Species

As part of ongoing studies on Magnolia sect. Macrophylla in North America (Mexico), unusual populations from the humid forests of Sierra Madre Oriental (central western Tamaulipas State) were found. They are here formalized as a new species, M. alejandrae. Its morphology, ecology, and conservation status are provided. A morphological comparison with similar species and diagnostic key for the species of M. sect. Macrophylla are also included. The names Magnolia ashei, M. macrophylla, and M. dealbata are lectotypified, respectively, on specimens preserved at NCU, and P and on a Zuccarini illustration. An epitype (at M) was chosen for M. dealbata.

A New Species

A new species, Laelia halbingeriana, and a new natural hybrid, Laelia ×oaxacana, both from the Sierra Madre Oriental in northern Oaxaca, Mexico, are described and illustrated. Laelia halbingeriana is similar to L. superbiens, from Chiapas through Nicaragua, differing in the proportionately shorter, stouter pseudobulbs, low, entire, distally white keels of the labellum and obscurely bilobed anther. Laelia ×oaxacana is applied to a hybrid swarm between L. halbingeriana and sympatric L. anceps. The hybrid can be distinguished from L. halbingeriana by the distichous (vs. spiral) raceme and the spreading petals oriented vertically (vs. distinctly arcuate and oriented horizontally), and from L. anceps in the stouter plants with two-leaved pseudobulbs and the proportionately narrower, waved sepals and petals.
