We present the first record of Morelet's crocodile Crocodylus moreletii for Hidalgo, Mexico. The crocodile was hunted in the estuary near the river by a local from the community Congreso Permanente Agrario, 13 km E from Huejutla at an elevation of 90 m asl.

We studied floral morphology and anatomy of seven genera of the tribe Hamelieae sensu Manns & Bremer with the goal to evaluate the potential of these characters in the circumscription of the tribe. Twenty two species of Hamelieae were studied as well as ten representative species of the Cinchonoideae, Ixoroideae, and Rubioideae subfamilies for comparative purposes. The Hamelieae members had stamens adnate to the corolla base, anther dorsifixed with introrse dehiscence, amphivasal vascular bundle in the filament, endothecium of one layer of cells, papillose stigma, axile placentation, orthotropous and unitegmic ovules, epidermal cells of the integument with tannins, and idioblasts with raphides in all whorls. Exostema and Hintonia (Cinchonoideae) share with Hamelieae the stamens adnate to the corolla base and the imbricate aestivation. However, these genera are unlike of the tribe because they have anthers with latrorse dehiscence, round filaments, ovoid styles with a constriction, anatropous ovules with basipetal orientation, and idioblasts with druses or crystal sands. Rubioideae and Cinchonoideae representatives unlike Hamelieae and species of Cinchonoideae studied have valvate and contorted to the left aestivation, anthers dorsifixed at the middle, stamens adnate to the throat of the corolla, and trichomes in the throat of the corolla tube. The imbricate aestivation, the occurrence of raphides, and the adnate stamens of the corolla base supported the relationships among Hamelieae and Cinchonoideae as suggested by molecular phylogenies. © 2013 The New York Botanical Garden.

Wood and bark anatomy of 42 species of Rubiaceae from 8 tribes were studied with the aim to assess whether the anatomical characters allow separation of species belonging to the different genera in Mexico and whether characters are related to the environment where they live or their habit. Two groups resulted in the phenogram, corresponding to wood type I and II sensu Koek-Noorman. Not all species of Bouvardia and Psychotria grouped in their respective genera and Notopleura anomothyrsa is different from the other species having fibertracheids and scalariform intervascular pits. The Arachnothryx, Chione, Exostema, Hintonia and Randia group with wood type I presents rhytidome, bands of sclereids and 3 types of crystals in the phloem, and are trees or shrubs of the seasonal dry forest and the cloud forest. The group with wood type II has a single periderm, endodermis, groups of fibers/sclereids and raphides in the phloem, and are shrubs of the tropical rainforest, seasonal dry forest, cloud forest, and pine-oak forest. Growth rings in these species may be associated with phenology and habitat conditions, but vessel diameter and density appear to have a strong phylogenetic signal. © 2015 Universidad Nacional Autónoma de México.
