meats. Ova/n/ {in Caricese enclosed in a utricle) 1-celled ; style short or 

 slender, 2-3-cleft, branches slender stigmatic ; ovule 1, basal, erect, anatro- 

 pons. Fruit a compressed or 3-gonous nut. Seed erect, free ; embryo 

 minute, inside the usually floury albumen. — Genera 60; species 3000, 

 universally distributed. 



The above Ordinal character applies especially to the Indian CyperacecB, and takes 

 no account of exceptions to it, which occur in extra-Indian species. 



I am indebted to Mr. 0. B. Clarke, F.R.S., for the following account of the 

 Indian Ci/peraceie. It will be observed that in it the citations of authors and of 

 Ploras have been almost restricted to those in which the species and their synonyms 

 lave been first indicated or described, and to the standard works of Kunth, 

 Boeckeler and Steudel (and of Boott in the genus Carex), to a good figure when 

 acceptable, and to the various Indian Floras, monographs, &c. The vast literature of 

 the order, so many species of which are scattered over large areas of the globe and 

 are hence described in many extra Indian works, renders this course unavoidable in 

 the case of a " Flora " which, like that of British India, must have circumscribed 

 limits. I have myself supplied the following olavis. — J. D. H.
