Deiregyne tenorioi Soto Arenas & Salazar, a new orchid species from the Mexican states of Hidalgo, Estado de México, Oaxaca, Puebla, and Tlaxcala, is described and illustrated. It is similar to D. eriophora (B.L. Rob. & Greenm.) Garay and D. chartacea (L.O. Williams) Garay, differing from the former in the sparsely glandular-pubescent inflorescence rachis and ovary (vs. lanuginose), odorless flowers and proportionately longer, narrower labellum with bright green to lemon yellow, narrow throat with straight sides (vs. golden yellow, wide throat with rounded sides); from the latter it differs in larger flowers with sepals and petals not tinged with greenish-brown below the middle, spreading lateral sepals (vs. strongly recurved), and proportionately longer, narrower distal labellum lobe.

When Mexico became independent in 1821, the first choice for a political system for the new country was a monarchy. In fact, the Plan of Iguala, which prompted the separation from Spain, called for Ferdinand VII or any member of his family to come rule over the novel nation. While such efforts did not prosper then and in fact precipitated a failed attempt for a national empire, the monarchist option remained alive for several decades, until a French intervention sponsored the enactment of Habsburg archduke Ferdinand Maximilian as emperor of Mexico. When that attempt was defeated in 1867 it marked the end of monarchism there. One of the main promoters of such a political system was Lucas Alamán. A member of a miner’s family from Guanajuato, he became an important and influential statesman of independent Mexico. From 1821, when he first participated in the Spanish congress, until his death in 1853, Alamán, like other thinkers who lived through a transitional period, held paradoxical views; while he promoted industrialization and economic development, he maintained more-traditional views on politics and rather ancestral conceptions regarding the treatment of Indian communities. Either as minister of foreign relations, congressman, or advisor to various governments, he defended his ideas, and more than once they aimed for a monarchist option. His career illustrates the quandaries and dilemmas that the officials of Hispanic America and Old Spain as well confronted in modernizing their societies. As he got involved in public office, he also became the administrator of the Duke of Terranova and Monteleone’s state in Mexico; such a position provided him—through the British agents of the Neapolitan-Sicilian nobleman—with a regular source of information on the European scene. Thus, Alamán was one of the most learned public officials of his time. He also wrote historical works that granted him recognition in academic institutions, such as the Philosophical Society of Philadelphia.
