CONTRIBUTION TOWARDS A FLORA OF CAITHNESS 113 



LEONTODON AUTUMNALIS, L. \ Flowering from middle of July. A 



small one-flowered form with black hairs on the phyllaries ; not 



quite the same as the var. pratensis. Is not our name for this 



latter variety wrong ? I am unable to separate some of our 



specimens from the var. nigro-lanafa, Fr. I believe the 



following names all refer to the same plant, or forms of it : 



L. autumnalis, L., var. nigro-lanatus, Fr., "Flora Hallandica," 1817.
