viii. INTRODUCTION. 



need to emphasise the importance of systematised phenological 

 records as indices to what one may perhaps call resultant climate, 

 or to point out that the nett effect of temperature, rainfall, 

 latitude, elevation, exposure, etc., is summed up in, e.g., the 

 dates of flowering of plants without any ambiguity or possibility 

 of error." 



Botanists visiting the Scilly Islands will find much that will 

 interest them in an article on Tresco Abbey Gardens by Dr. 

 A. W. Hill, F.R.S., published in the Kew Bulletin of 

 Miscellaneous Information, No. 5, 1920. The suggestion is made 

 therein that it would appear possible to set up a Flax (Phormium) 

 industry in co-operation with Cornwall, and to keep a Cornish 

 Flax Mill working throughout the year. 



In his Presidential Address to the South-eastern Union of 

 Scientific Societies, 1918, on the Dispersal of Fruits and Seeds 

 by Ocean Currents and Tides, Sir Daniel Morris noted that a 

 seed of the Horse-eye, Mucuna urens, which is a native of the 

 West Indies, had been picked up in Cornwall. 



A note by Mr. F. Rilstone, dealing with the new Cornish 

 Mosses and Hepatics from the eastern half of vice-county 1 

 (West Cornwall), was issued in the Journal of the Royal Institu- 

 tion of Cornwall, 1917-18, pp. 310-13. A further article by Mr. 

 Rilstone, entitled " Cornish Mosses and Hepatics," was pub- 

 lished in the Journal of Botany, 1919, pp. 3-10. 



A note by Miss G. Lister, published in the Journal of 

 Botany, 1920, pp. 127-9, deals with the information relating to 

 Mycetozoa from Cornwall, which was brought together by the 

 late Dr. Alfred Adams, who collected mainly at Looe and the 

 surrounding country, and others. 



Quite apart from the mere systematic recording of localities 

 in which the Cornish flowering plants, ferns, mosses, liverworts, 

 lichens, and fungi occur, an enormous amount of interesting work 

 still remains to be carried out in the demain of cecology, i.e., 

 the branch of biology dealing with the relations of living plants 

 in their surroundings, their habits, modes of life, etc.. in which, 

 it has been said, the botanical morphologist, physiologist, and 

 systematist, happily meet.
