xiv PREFACE, 
"Two species are found on the Khasiya Hills, both 
are fixed to rocks or stones and both are half immers- 
Epacridee.—One species is found at Singapore 
which can scarcely be called or placed in Polynesia. 
Campanulacee.—In Codonopsis and Cyclocodon 
a curious anomaly occurs. The parallel of which is 
to be looked for in Barclaya, I allude to the cohesion 
of the tube of the corolla to the ovarium, that such 
is the case I take it to be proved by the consideration 
of a Khasiya species Cyclocodon distans, in which 
the calyx is totally inferior and removed to some — 
distance, from the base of the ovarium. M. A. 
Decandolle has I believe described what I call the 
calyx of Codonopsis as an involucrum. but this 
view is not borne out by structure.  Deboro, Feb.

Scevolea——One species of Scevola occurs abun- 
dantly on the Tenasserim coast. 
Three species occur in British Burma, betwedil the 
parallels of 16,30 and 12th, Lat. 
Cucurlitacea.—The anthers are one-celled at least 
in several of the genera. They are always extrorse. 
There is no arillus, a genuine arillus is an extension 
of the funicle and never forms a perfectly closed
