2. *Arabis petraea (Lam.) _var._ grandifolia (Druce). Scotch mountains. "The larger flowers alone distinguish this." (J. D. H.) 3. Arabis ciliata (R. Br.). In Nyman's _Conspectus Florae Europaeae_ this species is given as found in England and Ireland only. "A very much disputed form of a plant of very wide distribution in Europe and North America." (J. D. H.) 4. Brassica monensis (Huds.). "This and the continental _B. cheiranthus_ (also found in Cornwall) are barely distinguishable from one another." (J. D. H.) 5. Diplotaxis muralis (D. C.) _var._ Babingtonii (Syme). South of England. "A biennial or perennial form; considered to be a denizen by Watson." (J. D. H.) 6. *Helianthemum guttatum (Mill), _var._ Breweri (Planch). Anglesea. "Very doubtful local plant. _H. guttatum_ (true) has lately been found in the same locality." (J. D. H.) 7. *Polygala vulgaris (L.), _var._ grandiflora (Bab). Sligo, Ireland. "A very distinct variety." (J. D. H.) 8. Viola lutea (Huds.), _var._ amoena (Symons). "_V. lutea_ itself is considered to be a form of _V. tricolor_, and _V. amoena_ the better coloured of the two forms of _V. lutea_." (J. D. H.) 9. *Cerastium arcticum (Lange), _var._ Edmonstonii (Beeby). Shetland Is. "But _C. arcticum_ is referable to the very variable _C. alpinum_." (J. D. H.) "Near to the European _C. latifolium_." (Ar. Bennett.) 10. *Geranium sanguineum (L.), _var._ Lancastriense (With.). Lancashire. "A prostrate local form growing out of its native soil in sand by the sea." (J. D. H.) Mr. Bennett writes: "I have grown _G. sanguineum_ and its prostrate variety in sand, and neither became Lancastriense." 11. Genista tinctoria (L.), _var._ humifusa (Dickson). Cornwall. "A decumbent hairy form confined to the Lizard." (J. D. H.) 12. Cytisus scoparius (Link.), _var._ prostratus (Bailey). Cornwall. "A prostrate form." (J. D. H.) 13. Anthyllis vulneraria (L.), _var._ ovata (Bab.). Shetland Is. "A slight variety." (J. D. H.) 14. *Trifolium repens (L.), _var._ Townsendii (Bab.). Scilly Isles. "A {361} well-marked form by its rose-purple flowers. Confined to the Scilly Isles." (J. D. H.) 15. *Rosa involuta (Sm.), _var._ Wilsoni. (Borrer.) Wales. "There are a multitude of forms or varieties of _R. involuta_, and _R. wilsoni_ is one of the best-marked, found on the Menai Straits and Derry." (J. D. H.) 16. Rosa involuta _var._ gracilis (Woods). "This is considered by many as one of the commonest forms of _R. involuta_." (J. D. H.) 17. Rosa involuta _var._ Nicholsoni (Crepin). "Another slight variety of _R. involuta_." (J. D. H.) 18. Rosa involuta _var._ Woodsiana (Groves). "A Wimbledon Common variety of _R. villosa_." (J. D. H.) 19. Rosa involuta _var._ Grovesii (Baker). "Mr. Baker thinks this of no account." (J. D. H.)
