9831 MR. H. H. W. PEARSON ON THE 
Pedicularis zeylanica, Benth., Exacum Walkeri, Arn., and 
E. zeylanicum, Roxb., are stated by Trimen to be annuals. The 
first of these is a marked perennial, with a large persistent woody 
rootstock; both species of Exacum are certainly biennial, if not 
perennial. 
In the following list the names of endemic species are printed 
in italics. A short description of the more apparent features of 
biological interest is appended to each species ; a full systematic 
description will be found in the ‘Flora of British India,’ or in 
Trimen's * Handbook to the Flora of Ceylon, or, in the case of the 
vascular Cryptogams, in Baker's * Synopsis Filicum’ (1883), or 
* Fern-Allies’ (1887), to which references are given. The collee- 
tion numbers, with the elevation from which each specimen 
was obtained, are given at the end of each description. The 
collection is incorporated in the Herbarium of the University 
of Cambridge.
