S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations.

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.

GUNATILLEKE2 * IUCN - The World Conservation Union, Sri Lanka Country Ofice Department of Botany, University of Peradeniya, Peradeniya. (Received: 26 October 2001 ;accepted: 06August 2002) Abstract: This study was carried out to document some ecological aspects of weeds in an irrigated rice field ecosystem in Bathalagoda, Sri Lanka. The study was conducted from November 1995 to August 1997 in two rice fields which differed in weed management practices. A total of 89 vascular plant species of rice-weeds belonging to 21 families, 31 genera of algae and three genera of macrofungi were recorded from the two rice fields surveyed.Among the dicotyledonousweeds recorded, one species (Elatine triandra Schkuhr.) is a new record for Sri Lanka. Of the weed flora recorded from the rice field ecosystem, 45 species were mesophytes, 41 species were hygrophytes, while three species were hydrophytes. The species composition of the weed flora was highest in the rice field bunds (82 species), while the rice field proper harboured 41 weed species, and 24 weed species occurredin the ditch habitat. In both rice fields, the temporal pattern of variation of weed species richness was similar. The weed species richness on the bunds differed according to the surface on which they occurred, and exhibited a clear spatial variation. The study also reflects the impacts of different weed management practices on the species diversity of weed flora in a rice field ecosystem.

The North America.N Species of Isachne
• THE NORTH AMERICA.N SPECIES OF ISACHNE. By A. S. HITCHCOCK. INTRODUCTION. This tropical genus of grasses is, in technical characters, anomalous in the tribe Paniceae, to which it belongs, in that the spikelet has two fertile florets instead of one. That is, throughout the tribe, with the exception of lsachne, the spikelet has one terminal fertile . floret and one sterile floret, this consisting of a lemma only, of a lemma and palea, or of a lemma, palea, and a staminate flower. In lsachne the lateral floret contains a perfect flower and normally develops a seed. There are seven species in North America, a few more in South America, and several in the tropics of the Old World. DESCRIPTION OF THE GENUS ANll SPECIES. • ISAClDIE R. Br. Isackru R. Dr. Prodr. Fl.

The type locality of the species is the Darjeeling district of West Bengal, India and the collection was made by C.B. Clarke in the year 1884. The present collection was made in 2012 from Cachar district of Assam (India) which also indicates its geographic range extension from the Darjeeling foothills to the Assam floodplain. In this paper a description of the species, a key, and an illustration are provided to facilitate identification. Priority conservation is highly recommended for this rare species. Key words: Assam, Barak Valley, Darjeeling, India Introduction The genus Isachne Brown (1810: 196) comprises ca. 90 species (Mabberley 2008) and is mostly distributed in tropical and warm temperate regions of Asia to Australia. The genus is mostly characterized by its hygrophilous habit, sub- globose to obovoid 2-flowered spikelets with florets disarticulating above the glumes, glandular or eglandular banded pedicels and sexually variable florets (Prakash & Jain 1984). In India, it is represented by 29 species out of which 18 are said to be endemic (Prakash & Jain 1984).

For an example, undesirable qualities outweigh their good points, at least Eichhorniacrassipes (Waterhyacinth) is beautiful in floating according to humans. Human activities create weed problems gardens but can rapidly log waterways, cause to flood and since no plant is a weed in nature. Though human may try to making navigation impossible.

Their pattern of spread Through manipulation, human control certain weeds, while other and adapting features are help to grasp cultivated lands. Sri more serious weeds may thrive due to favorable growing Lanka has a poor record of managing weeds, largely due to conditions. Weeds are naturally strong competitors, and those inadequate mechanisms to deal with them early or prevent their weeds that can best compete always tend to dominate[2].Both entry through border protection. Recent stakeholder consultations humans and nature are involved in plant-breeding programs. The identified insufficient funding for on-ground works and for main difference between the two programs is that humans breed research and the absence of a central coordination mechanism as plants for yield, while nature breeds plants for survival[2].
