ABSTRACT RESUMEN

New reports of Garrya ovata ssp. goldmanii Se encontraron como nuevos registros para (Wooton & Standl.) Dahling and Beschorneria Veracruz Garrya ovata ssp. goldmanii calcicola García-Mendoza are presented for (Wooton & Standl.) Dahling y Beschorneria the state of Veracruz, Mexico. Both taxa were calcicola García-Mendoza, ambas se found on karstic hills in the arid zone of encontraron en los cerros calizos de la zona Veracruz near Tenextepec, Perote. Garrya árida veracruzana, en los alrededores de ovata ssp. goldmanii is a small shrub measuring Tenextepec, Perote. Garrya ovata ssp. up to 1.5 m tall, which contrasts considerably goldmanii es un arbusto pequeño que mide with G. laurifolia Benth. ssp. laurifolia and G. hasta 1.5 m de alto, contrastando laurifolia Benth. ssp. macrophylla already considerablemente con G. laurifolia Benth. ssp. registered for Veracruz.

INTRODUCTION METHOD

During botanical explorations in the isolated Herbium vouchers of all material collected were xerophyll scrubs on rocky substrate of the deposited at XAL and original descriptions and Cofre de Perote rain-shadow region in central keys were consulted for determinations. Veracruz we came upon a small population of Garrya Douglas ex Lindl. and another of RESULTS Beschorneria Kunth. The genus Garrya is distributed in the New World and ranges from On comparing Garrya ovata with the only the Pacific Northwest of the USA through species of this genus known from Veracruz, G. Mexico, Guatemala, the Greater Antilles and laurifolia Benth., Espejel (1983), we have the volcanic peaks of Panama (Dahling, 1978). come to the conclusion that the specimens The genus Beschorneria is practically endemic collected during this expedition belong to G. to Mexico, distributed along the Sierra Madre ovata ssp. goldmanii (Wooton & Standl.) Oriental with one species reaching into Dahling. Guatemala (Galvan, 1990).
