DIAND. MONOG. 5 



longer leaves, brighter blue flowers, and shorter style, it is known 

 from all the varieties of / '. serjnjU. 



3. V.saxutilis {blue Rock Speedwell), raceme lax few- flowered 

 corymbose, upper leaves oblongo-obovate subserrate, stems 

 spreading, capsule ovate longer than the calyx. E. B. t. 1027. 



Hab. Rocks on mountains, very rare. Ben Lawers, G. Don and Mr. 

 J.Mackay. Mael Greadha, Breadalbane, Mr. Borrer. H.July. 1/. 



Stems woody, very straggling ; j?ow;eriHo- 6ranc/ies long, ascending; 

 lower leaves shorter than tlie upper ones, very obtusely serrated be- 

 low the point : — in these respects the figure in E. B. does not ac- 

 cord with my specimens. Corymb (rather than raceme) with from 

 3 to 7 flowers, in fruit lengthening into a short raceme. Pedicels 

 much longer than the floral leaves. Corolla deep and brilliant blue, 

 by far the most beautiful of the genus. Cal. in four deep, oblongo- 

 obovate segments, more or kss downy. Capsule veiy large and 

 ovate, the two valves frequently parting some way down from the 

 apex, so as to appear 4-valved. 



4. V. fruliculosa {flesh- coloured procumbent Speedwell), ra- 

 ceme mauy-flowered subspicate, upper leaves oblong serrate, 

 stems procumbent, capsule ovate scarcely longer than the ca- 

 lyx. E. B. t. 1028. Don's Fuse. 202. 



H.VB. Scotland, the Rev. Dr. Walker. Has been found on Ben Lawers, 

 Sm. in E. B. Mr. Don supposes Dr. Walker gathered it on Ben 

 Cruachan, and that the V. saxatilis was mistaken for it on Ben Law- 

 ers ; so that the identity of this plant as a native requires to be con- 

 firmed*. H. July, August. 1/. 



Stems less straggling at the base than the last ; Jlcwering branches 

 longer ; but never so large on the native rocks in Switzerland as the 

 figure in E.B., nor so haiiy. Indeed it approaches very near to 

 V.saxat., especially the few-flowered varieties; so much so, that, 

 except what is given in the above specific character, I can point out 

 no further marks of distinction than the flesh-coloured blossoms. 

 Linnieus and Haller supposed them to be varieties of each other : 

 De Candolle questions if they are permanently distinct ; but Schra- 

 <Ier, Wahlenberg, and Smith, high authorities, wonder that there 

 ever should have been a doubt of their right to rank as species. 

 ** Spikes or Racemes axillary {plants perennial). 



5. Y.scutellata {Marsh Speedwell), racemes alternate, pedicels 

 divaricated, leaves linear somewhat toothed, stern nearly erect. 

 Lightf. p. 74. E. B. t. 782. 



Hab. Bogs and sides of ditches ; not un'Vequent : as in Kenmuir and 

 Possil bogs, and about Frankfield and Huggenfield Lochs, near 

 Glasgow, Hopk., who has also found a hairy variety at Possil. 

 South side of Duddingston Loch, Maiigh. Marshes about Edin- 

 burgh, Perthshire, Kinross-shire and Angus-shire^ Mr.Arnott. Fl. 

 July. %. 



Racemes very rarely opposite. Pedicels or partial footstalks remark- 



* It has been planted by Dr. Walker on a garden wall at Collington, 

 Edinburgh.
