4 MR. C. B. CLARKE ON THE 
specifie distribution and have printed only the abstraet tables. 
The tabulations for the distribution of species can be con- 
structed by anyone who wants them out of this paper. I publish 
the paper, firstly as recording and defining geographically the 
whole material on which the Cyperaceæ (in the * Flora of British 
India") stand’; and secondly, as the ground for some speculations 
which I have added regarding the derivation of the existing Flora 
of British India. 
The 11 subsubareas of tabulation adopted are (see Map) :— 
(1) West Himalaya. 
(2) India Deserta. 
(3) Malabaria. 
(4) Ceylon. 
(5) Coromandelia. 
(6) Gangetic Plaiu. 
(7) East Himalaya. 
(8) Assam. 
(9) Ava. 
(10) Pegu. 
(11) Malay Peninsula. 
It is unnecessary to write out fully the boundaries of these 
subsubareas, as the Map shows them more quickly. But I may 
here explain the reasons why some of the lines are drawn where 
they are :— 
(1) The eastern boundary of this subsubarea in Nepal is 80? 30' 
Long. E. It is so drawn in order that Wallich's own 
collections made with his headquarters at Katmandu may 
go with Hooker's Tambur plants, and may be tabulated 
separately from the plants Wallich got from Kumaon, 
with which last go Duthie's West Nepal plants. 
The south boundary is supposed the line between the 
hills and the plains, say the line of 1500 fect above sca. 
(2) The subsubarea is essentially that of the Indian Desert, the 
Punjab Plain, Sindh and Belcochistan. Gujarat is supposed 
wholly in Malabaria, Malwa wholly in subsubarea (2), which 
also takes in Quetta and Kuram.
