BOTANY 



Hybrids are supposed frequently to be produced among the species 

 of several genera, such as Epilobium, Carduus, Cnicus, Verbascum, etc. ; in 

 the case of the first of these genera, Mr. N. E. Brown in the third part 

 of the supplement to the third edition oi English Botany, gave in 1892 

 twenty-seven cases of hybrids, the following nine of which occurred in 

 Devon : — 



Epilobium aggregatum, Celalcovsky, a supposed cross between E. mon- 



tanum and E. obscurum 

 E. aschersonianum, Haussknecht, between E. lanceolatum and E. 



parviflorum 

 E. dacicum, Borbas, between E. obscurum and E. parviflorum 

 E. lamotteanum, Haussknecht, between E. lanceolatum and E. obscurum 

 E. neogradiense, Borbas, between E. lanceolatum and E. montanum 

 E. rivulare, Wahlenberg, between E. palustre and E. parviflorum 

 E. schmidtianum, Rostkov., between E. obscurum and E. palustre 

 E. thuringianum, Haussknecht, between E. tetragonum {adnatum) and 



E. obscurum 

 E. iveissenburgense, F. Schultz, between E. tetragonum (adnatum) and 

 E. parviflorum 



To this list may be added : — 



E. ligulatum. Baker, between E. obscurum and E. palustre

The literature dealing with the flowering plants of the county gene- 

 rally includes the following works : — 



Camden's Britannia^ edition by Edmund Gibson (1695). The catalogues of plants given 

 at the end of each county were communicated by ' the great botanist of our age, 

 Mr. Ray ' ; that for Devonshire, on page 42, consisted of ten species, nine of them 

 being flowering plants. 



John Ray : Synopsis methodica stirpium britannicarum, turn indigents, turn in agris cultis locis 

 suis dispositis ; odditis generum characteristicis specierum descriptionibus et virium epitome. 

 Editio tertia (i 724). Fourteen species of flowering plants are mentioned as occurring 

 in Devonshire. 



Camden's Britannia, edition by Richard Gough (1789). The list of 'rare plants found 

 in Devonshire,' on page 41, contains thirty-five flowering plants. 



Richard Polwhele : The History of Devonshire vol. i. (1797), chap. 5, pp. 81-100, 'The 

 indigenous plants of Devonshire.' ' From the eastern part of the county Mr. Wel- 

 land, rector of Talaton, and Miss Burges of Tracey near Honiton ' favoured the 

 author * with botanical observations ; from the neighbourhood of Exeter, Mr. 

 Weston, late rector of Mamhead, and Mr. Swete of Oxton house [in Kenton] ;

 Wavell of Barnstaple ; and from the Southams Mr. Cornish of Totnes and Mr.

Dawson Turner and James Sowerby, in the Transactions of the Linnean Society of London 

 (1800) V. 234-41 ; 'Catalogue of plants observed in a tour through the western 

 counties of England made in June 1799.' This catalogue mentions seventeen species 

 including six cryptogams as occurring in Devon. 



Dawson Turner and Lewis Weston Dillwyn : The Botanist's Guide through England and 

 Wales (1805), i. 194-212, 'Devonshire.' This enumerates nearly a hundred 

 flowering plants for the county.
