XXX INTRODUCTION. 



About six years after the publication of Banks's work the Rev. John 

 Jacob, LL.D., Master of tlie Devonport Grammar School and Minister of 

 St. Aubyn Chapel in the same town, commenced the publication of the 

 West Devon and Cornwall Flora. It too was issued in monthly parts 

 at one shilling each, but was also left unfinished in the year 1837, after 

 eighteen numbers had appeared, containing notices of 229 plants. Very 

 many of the stations given by Jacob belong to Pljonouth. Just before 

 the commencement of this work Watson's Neio Botanist's Guide, vol. i., 

 was published, but with few Plymouth stations in the plant lists for 

 Cornwall and Devon. Two years later vol. ii. appeared, with several for 

 the town and its neighbourhood, most of the new ones having the name 

 of Dr. Bromfield attached. 



About the time that Mr. Banks and Dr. Jacob were investigating the 

 botany of Devon and Cornwall, the Rev. John Tozer, a clergyman of the 

 diocese of Exeter, was also giving considerable attention to it, and his 

 name is found in connection with some Plymouth plants, though it does 

 not appear that he himself ever published anything concerning them. 

 Like Mr. Banks, he was a correspondent of Sir Wilham J. Hooker's, and 

 his name is found in some of the early editions of the British Floi'a. 



In 1841 the British Association met at Plymouth, and the Rev. W. S. 

 Hore, M.A., F.L.S., now Vicar of Shebbear, in North Devon, brought before 

 its members a "List of Plants found in Devonshire and Cornwall, not 

 mentioned by Jones in the Flora Devoniensis. " In it a few additional 

 Plymouth species appear. This list was afterwards inserted in the 

 Phytolorjist, vol. i. (p. 160-63.) It was followed in the succeeding volume 

 (p. 239, 40) by a paper from Mr. Hore relative to the discovery of 

 Orohanche amethystea, Thuil., at Whitsand Bay, within the Cornwall 

 portion of the area. This latter article is dated June 27th, 1845. Subse- 

 quent volumes of the Pkytologist contain a few additional notices of 

 Plymouth plants in communications from F. H. Gouldmg, F. P. Pascoe, 

 I. \V. N. Keys, T. B. Flower, and others. The discovery of Hypericum 

 linariifolium within the area was first announced in a short-lived local 

 serial, the South Devon Literary Chronicle, in the year 1846. Mr. F. P. 

 Pascoe, in an article inserted m the Botanical Gazette (vol. ii. p. 37-9) in 

 1850, added one or two species to the Plymouth list. In 1860 the Rev. 

 T. F. Ravenshaw, m.a., brought out a New List of the Flowering Plants 

 and Ferns growing wild in the County of Devon, which work was re- 

 issued, with a Supplement in 1872. Some of the stations given therein 

 with the authors initials appended are previously recorded ones, only 

 verified by him, as he himself informs us. Between the years 1865 and 

 1871 a much larger work, Flora of Devon and Cornwall, by I. W. N. 

 Keys, was publislied in the " Transactions of the Plymouth Institution 

 and Devon and Cornwall Natural History Society." In Mr. Ravenshaw's 

 work there are few new stations that belong to Plymouth, but in Mr.
