VLAN OF THE FLOEA. 



The Flowering Plants and Ferns found in the country within twelve 

 miles of Plymouth are arranged and named m accordance with The 

 London Catalogue of British Plants, ed. 7. The number precedmg each 

 species is that belonging to it in the Flora, and has no reference to the 

 Catalogue. The English name is the one given by Dr. Boswell in English 

 Botany, ed. 3. When a second is added it is a local name. This will be 

 seldom found, as local names have been bestowed on only a few of the 

 plants. The position of each as a Plymouth species is next shown by its 

 assignment to one or other of the classes — Native, Denizen, Colonist, 

 Casual, or Ahen— as these are set forth m Mr. H. C. Watson's works ; 

 and then the nature of the spots Avhere it grows Avithin the area is stated. 

 These particidars are followed by seven graduated terms, which mark its 

 comparative frequency therein. They are : 



Very common. Rather rare. 



Common, Rare, 



Rather comm^n, Very rare. 



Locally common. 

 Next its fiowermg season m the area is in most cases given. The 

 stations follow under the six Districts, miless the plant is ' very common,' 

 and of course generally distributed, when the words ' area general ' stand 

 instead. In a few cases, however, exceptional cu'cumstances make it 

 desirable to place some special stations for very common plants on record ; 

 so here and there certain stations will be found under them. Every one 

 of the six Districts has a separate paragraph, when special stations are 

 given. Districts I. II. are preceded by a C, to mark the county of Corn- 

 wall ; III., IV,, V. and VI. by a D, to show that tliey are in Devon. The 

 earhest recorded station, with the authority for it, is placed first in order. 

 Every station not resting on the author's observation alone, has, folloAving 

 it, a reference to the authority on which it appears. Previously recorded 

 stations, verified by the author, have the mark ! attached to them, 

 frequently followed by the date of the verification. Lastly, remarks are 

 often added concerning the plant as a Plymouth species, and sometimes 

 particulars of a less local character, resultmg, however, from observations 

 made Avithin the area. 



Brackets [ ] are used to enclose stations, &c. , where a plant is either 

 known or believed to be extinct. 

 Parentheses ( ) to enclose statements suspected to be erroneous.
