LITHOSPERMUM 355 



This form, which has the flowers permanently of a pale yellow 

 colour, was rather plentiful in Windsor Great Park in 1886. I have 

 also seen it at Long Moor, Finchampstead, and Swinley. When the 

 flowers are whitish it is the var. paUidaj Brebisson, Fl. de la Nor- 

 mandie, 208. 



The tube of if. versicolor is longer than that of M. collina. 



A common form in North Scotland has many stems rising from the 

 root ; it is the var. muUicaulis, Bosch, Fl. Batav. 160. The flowers in 

 my Sutherland plant were all pale blue. 



M. versicolor occurs in all the bordering counties.
