By N. L. Britton. The list of species of Cyperaceae published herewith is based primarily on collections in the herbarium of the New York Botani- cal Garden, supplemented by those in the herbarium of the Depart- ment of Public Gardens and Plantations, and by notes taken at the herbaria of the Royal Gardens at Kew and at the British Museum of Natural History. The principal literature consulted has been the Monograph of the West Indian Cyperaceae by the late Mr. C. B. Clarke, published by Professor Urban in the second volume of his Symbolae Antillanae, Grisebach's Flora of the British West Indies, and the several papers of O. Boeckeler. Most of the species may be regarded as satisfactorily known, and their general distribution ascertained, but a considerable num- ber are, as will be seen in the enumeration, known only from single specimens secured by the older collectors, so that very much remains to be done in order to ascertain their relative abundance or rarity, their habitats and distribution ; in some cases the only record that we have is that the specimen was collected somewhere on the island, and in a few instances it is suspected that errors have been made in the origin of the plant cited, through a mixture of labels in the older herbaria, or in some other way. I have accepted the generic limits outlined by Mr. Clarke in the paper above cited with the exception of his treatment of Cyperus and its segregates, where I have accepted the view of previous authors in taking Cyperus in its broad sense rather than recogniz- ing the genera Pycraeiis, Mariscus, and Torulinimn, as I believe the characters depended on by Mr. Clarke for the maintenance of these genera are too vague for satisfactory use. It is my opinion that either this course must be taken, or tha.tEleocharis, Scirpus and Ryn- chospora must also be split up in order to be consistent. On the other hand, I accept the genus Ahildgaardia as distinct from Fim- hristylis, though I am not altogether clear that this position is readily defensible. I have also diverged from Mr. Clarke's treat- ment in accepting the generic name Steiiophyllus, for the plants he includes under Bulbostylis, the former name having evident priority and being based on a well-known type. The paper is submitted as a contribution to knowledge of the Jamaica flora from the Tropical Laboratory of the New York Bo- tanical Garden .at Cinchona, which is held as a research station through the cordial co-operation of the Colonial Government. One of the great needs of this research station is a more accurate know- ledge of the flora of the island for the use of students either in residence there or at other institutions, and it is hoped that such a descriptive flora may be prepared in co-operation with the botanists of the Government at no distant date. In order to accomplish this, however, a very large amount of additional exploration must be done ; the co-operative arrangement now in progress is rapidly supplying much needed material through the collecting trips of Mr. William Harris, Superintendent of Hope Gardens, but his valu- able time for this purpose is naturally limited and should be sup- plemented by the work of other collectors in order that the infor- mation necessary may be more rapidly obtained. References to specimens and their collectors have been restricted for the most part to work of the last few years, the older speci- mens being comprehensively cited by Mr. C. B. Clarke in his monograph. Key to the Genera of Jamaican Cyperaceae. A. Fertile flowers perfect I.
