Epitypes are designated for the Mexican species Hechtia schottii and Hechtia stenopetala. Complete descriptions of the two taxa are presented as well as specimen citations and iconography depicting ...relevant characteristics of the species and plants in habitat. The first species, known only from the States of Campeche and Yucatán, was based upon pistillate material (old fruits and immature pistillate buds) and leaf fragments; the epitype adds the staminate flowers and complete leaves. The second species, restricted to the Veracruz State, was based upon a plant with old, open fruits; the epitype adds the staminate flowers and leaves.
A new species of Malaxis Solander ex Swartz (Orchidaceae, Epidendroideae, Malaxideae), M. medinae Carnevali & Noguera Savelli, from Trujillo State in Andean Venezuela is proposed herein. The new ...taxon is related to the widespread M. soulei L. O. Williams, a species found from the southwestern United States southward into Panama. The plants, however, are smaller (to only 12.7 cm) and have proportionally longer peduncles (to 4.5 cm) that bear fewer flowers (12 to 25 per spike) with a much more triangular labellum with parallel apical teeth (vs. convergent in M. soulei).
Tillandsia tehuacana I. Ramírez & Carnevali, a new species in the T. utriculata (L.) L. complex (Bromeliaceae) from Puebla, Mexico, is described and illustrated. The new entity is similar to T. ...makoyana Baker, but the rosettes are cylindrical (vs. funnelform), the leaves are coriaceous (vs. sclerotic), the leaves have a proportionately larger sheath compared with the lamina (vs. leaves with the sheath and lamina subequal), and the rachis of the inflorescence is sharply flexuous (vs. straight). The new species is also characterized by its habit, since it usually grows in dry thorn-scrub-cactus associations, while T. makoyana grows in different vegetation types, including oak and low deciduous forests. The new entity is also similar to T. pinicola I. Ramírez & Carnevali, but the new taxon differs by its larger rosette and inflorescence, its tubular rosette with leaves that are gray and purple and white lepidote on both sides (vs. a funnelform rosette with green leaves and only sparsely white lepidote abaxially), the floral bracts much shorter than the sepals (vs. subequal), the flowers ovate in shape (vs. tubular), and the three stigmatic lobes twisted together (vs. not twisted together).
A new species of Crossoglossa (Orchidaceae: Epidendroideae: Malaxideae), Crossoglossa acuminatissima, from Santander del Sur Department in Colombia, is described and illustrated, and its affinities ...are discussed. Malaxis tipuloides var. exigua is raised to the rank of species as Crossoglossa exigua, and its report from Venezuela constitutes the first record of the genus Crossoglossa in that country. /// Se describe Crossoglossa acuminatissima de Santander del Sur en Colombia y se provee una ilustración y una discusión de sus afinidades. Malaxis tipuloides var. exigua se eleva al rango de especie como Crossoglossa exigua, y su reporte para Venezuela constituye el primer registro del género en ese país.
Two new species in the Tillandsia utriculata (L.) L. complex (Bromeliaceae) from Mexico are proposed. Both are herein described and illustrated with their affinities discussed. The first new entity, ...T. aesii I. Ramírez & Carnevali from the states of Jalisco, Guerrero, and Oaxaca, is similar to T. makoyana Baker, but the new taxon has an open rosette with leaves that are green adaxially and white lepidote abaxially (vs. a funnelform rosette with gray leaves on both surfaces in T. makoyana), actinomorphic flowers with a light apple-green corolla (vs. zygomorphic with a purple to light purple corolla). The second taxon proposed here, T. pinicola I. Ramírez & Carnevali, from the state of Oaxaca, is also similar to T. makoyana, but is a smaller plant with a more compact growth habit and leaves with proportionally shorter leaf blades that abruptly attenuate from a broad sheath (vs. gradually attenuate into the proportionally longer blade) into a sub-acicular apex. It is also characterized by typically growing on pines, hence the epithet.
An undescribed species of Lophiaris Rafinesque (Orchidaceae, Cymbidieae, Oncidiinae) was detected while conducting a phylogenetic study of Trichocentrum Poeppig & Endlicher s.l. Lophiaris ...sierracaracolensis Cetzal & Balam is described from Sierra Caracol in the Central Depression of Chiapas, on the Pacific slopes of Mexico. The new species is illustrated, and its affinities are discussed. The novelty is related to L. straminea (Bateman ex Lindley) Braem, but the labellum isthmus is broader (to 3 mm wide), the claw of the dorsal sepal is very short (1.5 mm long) and wide, and the callus is 8-partite (vs. 5-partite in L. straminea).

Soc. 139: 248-259. 2012.—Epitypes are designated for the Mexican species Hechtia schottii and Hechtia stenopetala.

A new species of Tillandsia is proposed. It is similar to Tillandsia brachycaulos Schlechtendal and Tillandsia balbisiana Schultes f., two sympatric species. The new species is most similar to T. ...brachycaulos in flower and bract color, but the elongated inflorescences resemble those of T. balbisiana, although the branches are much shorter.
Tillandsia may-patii is proposed as a new species. The following species were previously unrecorded (or insufficiently documented) for the bromeliad flora of the Yucatán Peninsula: Aechmea ...bromeliifolia, Aechmea tillandsioides var. tillandsioides, Catopsis nutans, and Tillandsia juncea. Hechtia schottii is treated as an endemic to the flora of the peninsula. An updated checklist of the family Bromeliaceae for the Yucatán Peninsula is presented.
