FLORISTIC STUDIES IN NORTH CENTRAL NEW MEXICO, U.S.A. THE TUSAS MOUNTAINS AND THE JEMEZ MOUNTAINS

This paper represents the first of two contributions that cover the floristic diversity in north central New Mexico. The area encompasses the Tusas Mountains and the Jemez Mountains (including Sierra Nacimiento) of the Carson National Forest and Santa Fe National Forest. Also included is Bandelier National Monument, Valles Caldera National Preserve, Bureau of Land Management (Taos District), and other federal, state, and private lands west of the Rio Grande. The second paper will discuss the floristics of the portions of the two forests and periphery to the east of the Rio Grande, thus primarily the Sangre de Cristo Range. The goal of this two-part series is to enumerate results of the most intensive floristic inventory ever conducted in New Mexico. Here, we report on 19,929 numbered collections of vascular plants (the sum for the entire area covering more than 3.7 million acres is 35,857 new collections). A total of 1,384 unique taxa, including 93 infraspecics and 10 hybrids, are documented from 107 families. Of these, 154 are exotics (14 are designated as noxious in New Mexico), 22 are species of conservation concern, 28 represent first reports or their confirmation for New Mexico, and finally 17 are endemics to New Mexico. Based on verified material at four herbaria, 64 additional unique taxa are included in the Annotated Checklist; thus the grand total is 1,445. Este artículo es la primera de dos contribuciones que cubren la diversidad florística en el norte-centro de Nuevo México. Este área rodea las Montañas Tusas y las Montañas Jemez (incluyendo la Sierra Nacimiento) del Carson National Forest y Santa Fe National Forest. También están incluidos el Bandelier National Monument, la Valles Caldera National Preserve, Bureau of Land Management (Distrito de Taos), y otras tierras federales, estatales y privadas al oeste del Río Grande. El segundo artículo discutirá la florística de las porciones de los dos bosques y periferia al este del Río Grande. Primariamente la Cordillera Sangre de Cristo. El objetivo de esta serie de dos partes es enumerar los resultados del mayor inventario florístico intensivo llevado a cabo en Nuevo México. Aquí, citamos 19,929 colecciones numeradas de plantas vasculares (la suma para el área completa que cubre más de 3.7 millones de acres es de 35,857 nuevas colecciones). Se documentan un total de 1,384 taxa únicos, que incluyen 93 infraespecíficos y 10 híbridos, de 107 familias. De estas, 154 son exóticas (14 se designan como no
