UNITED STATES DEPARTMENT OF AGRICULTURE INVENTORY No. 79 Washington, D. C. T Issued March, 1927 SEEDS AND PLANTS IMPORTED BY THE OFFICE OF FOREIGN PLANT INTRO- DUCTION, BUREAU OF PLANT INDUSTRY, DURING THE PERIOD FROM APRIL 1 TO JUNE 30,1924 (S. P. I. NOS. 58931 TO 60956) CONTENTS Page Introductory statement 1 Inventory 3 Index of common and scientific names _ 74 INTRODUCTORY STATEMENT During the period covered by this, the seventy-ninth, Inventory of Seeds and Plants Imported, the actual number of introductions was much greater than for any similar period in the past. This was due largely to the fact that there were four agricultural exploring expeditions in the field in the latter part of 1923 and early in 1924, and the combined efforts of these in obtaining plant material were unusually successful. Working as a collaborator of this office, under the direction of the National Geographic Society of Washington, D. C, Joseph L. Rock continued to carry on botanical explorations in the Province of Yunnan, southwestern China, from which region he has sent so much of interest during the preceding few years. The collections made by Mr. Rock, which arrived in Washington in the spring of 1924, were generally similar to those made previously in the same region, except that a remarkable series of rhododendrons, numbering nearly 500 different species, many as yet unidentified, was included. Many of these rhododendrons, as well as the primroses, delphiniums, gentians, and barberries obtained by Mr. Rock, promise to be valuable ornamentals for parts of the United States with climatic conditions generally similar to those of Yunnan. -

Ii \ T MEXICAN GRASSES in the UNITED STATES NATIONAL
■ . ~+j-,r?7-w- - i i - . \ t MEXICAN GRASSES IN THE UNITED STATES NATIONAL HERBARIUM. By A. S, Hitchcock INTRODUCTION. The following list of grasses, based entirely upon specimens in the United States National Herbarium, is a preliminary paper, in which the scattered data upon Mexican grasses have been brought together and arranged in a convenient form. The species included have been accepted, for the most part, in their traditional sense. It has been impracticable to examine the types of many of the earlier described species since these specimens are located in European herbaria. For this reason the synonymy has been confined mostly to those names that could be fixed by an examination of American types, or concerning the application of which there was little doubt. The largest number of unidentified names are found in Fournier's work on Mexican grasses.1 This results from the incomplete or unsatis- factory descriptions and from the fact that the specimens cited under a given species either may not agree with the diagnosis, or may belong to two or more species, at least in different herbaria. An examination of the original specimens will undoubtedly lead to the identification of the greater part of these names. There are several specimens that have been omitted from the list because they have not been identified and are apparently unde- scribed species. They belong to genera, however, that are much in need of critical revision and further study of them is deferred for the present. In subsequent articles it is hoped to work out the classifi- cation of the tropical American grasses upon a type basis KEY TO THE GENEBA. -
Poaceae) De México Species Richness, Classification and a Checklist of the Grasses (Poaceae) of Mexico
Artículo de investigación Riqueza de especies, clasificación y listado de las gramíneas (Poaceae) de México Species richness, classification and a checklist of the grasses (Poaceae) of Mexico J. Gabriel Sánchez-Ken Resumen: Antecedentes y Objetivos: En 2006 se dio a conocer el catálogo de las gramíneas de México, pero desde entonces tanto la clasificación como la apa- rición de especies nuevas cambiaron las cifras de esta familia en México y en el mundo. El objetivo principal de este estudio fue actualizar la lista de taxa en México, reuniendo el mayor número posible de bases de datos en línea. Otros objetivos incluyeron la comparación de la riqueza de especies de la familia Poaceae entre los países con mayor diversidad, así como analizar la riqueza de sus taxa a nivel estatal y por categorías taxonómicas. Métodos: Se consultaron bases de datos en línea, tanto nacionales como extranjeras, que incluían ejemplares de referencia de México, se descarga- ron y se curaron, además de una confirmación visual de la identidad de un gran porcentaje de ejemplares. Se extrajeron los nombres de las especies, estados donde fueron colectadas y los acrónimos de los herbarios. La base resultante se complementó solo con bibliografía a partir de 2006 y la no incluida en el catálogo que mostraba ejemplares de respaldo. Resultados clave: Se revisaron 227,973 registros que contabilizaron, en total, 1416 taxa, que incluyen 215 géneros, 1312 especies y 214 categorías infraespecíficas. Del total de especies, 1092 se consideran nativas y 224 introducidas (cultivadas y/o malezas). Las especies endémicas de México son 304 (27.83%) o 311 (28.10%) si se consideran categorías inferiores. -

Evolution of Grasses and Grasslands in South America
TAXON 24(I): 53-66. FEBRUARY 1975 EVOLUTION OF GRASSESAND GRASSLANDS IN SOUTH AMERICA Arturo Burkart* Summary This is a discussion of the South American grasslands from the standpoint of their evolution and composition. The tribes are considered in relation to climate, and grasses are classified as mega-, meso-, or microthermic with respect to their temperature requirements. The principal grassland regions are three: (A) Tropical and Subtropical, which include the Llanos of the Orinoco River system and the Campos Cerrados of Central Brazil; (B) Temperate, including the Pampa of Argentina and the Campos of Uruguay; and (C) Cold Country Grasslands, which are the Steppes of the high Andes and Patagonia, and also the Pairamos of Colombia and Ecuador. Some attention is given to the floristic composition of each of these regions. The subject of endemism is dealt with, as well as the problem of disjunct distribution. Included is a discussion of changes brought about by agriculture and ranching in historic times, and what may be expected in the future. INTRODUCTION The Gramineae, with about 6oo genera and some 6ooo species, is one of the largest families of flowering plants. It is a truly cosmopolitan group, and remarkable because of the capacity of its members to form the domi- nant vegetation over large areas of the earth's surface. The terms steppes, savannas, prairies, pusztas, campos or pampas all refer to vegetation types in which grasses are dominant. To quote Ronald Good (1953; p. 53) "Pride of place must certainly go to the Gramineae . ., the great family ... Not only do the grasses reach to the furthest land in the north and to the borders of Antarctica in the south, but their degree of distribution is usually particularly complete and continuous. -

Mechanical Recovery of a Native Forest with Shrubs of the Espinal
DOI: 10.26650/forestist.2018.392323 Forestist 2018, 68(2): 78-86 Original Article Mechanical recovery of a native forest with shrubs of the Espinal Ecoregion (Argentina) Espinal Ekolojik Bölgesindeki bir ormanda mekanik müdahele ile çalılar üzerinde sağlanan iyileşme (Arjantin) Rafael Alberto Sabattini , Julián Alberto Sabattini , Juan Carlos Cian , Mauro Lindt Chair of Ecology of Agricultural Systems, Faculty of Agricultural Sciences, National University of Entre Rios, Entre Ríos, Argentina ABSTRACT The invasion of woody plants in various parts of the world has been a longstanding concern in livestock produc- tion due to the expected negative impact on secondary production. Native forests cover 30% of the earth’s land surface. A great part of the livestock production of Entre Ríos is developed in these ecosystems, which have been highly degraded due to inadequate cattle management, and the invasion of shrub species. The aim of this study was to evaluate the natural pasture recovery in a degraded native forest, subjected to a mechanical intervention with a frontal roller-chopping, in order to increase the grazing area and improve secondary productivity. The study was carried out in Paraná Department (Entre Ríos, Argentina). On 15/12/2014 a mechanical intervention was carried out with a frontal roller-chopping designed by the Chair Ecology of Agricultural Systems. To evaluate the dynamics of the recovery of the natural grassland of the native forest, seven measurements were made on the following dates: 15/05, 12/06, 28/07, 11/09, 27/10 and 21/12/2015, and 22/02/2016. The vegetation cover was measured with the line intercept method and phytomass production.
