 partly dissected from the side (x 7). (3) Pollen-grains. a, bright blue limb of the corolla; b, white 

 radial streaks ; c, yellow centre of the corolla ; d, stamens ; e, stigma ; y, nectary. 



The following were recorded by the observers, and for the localities stated. 



Bail (West Prussia), 2 hover-flies (Eristalis sp., and Helophilus sp.) and 2 

 butterflies (Pieris napi Z., and Polyommatus phlaeas Z.) (Bot. Centralbl, Cassel, ix, 

 1882). Scott-Elliot (Dumfriesshire), a hover-fly (' Flora of Dumfriesshire,' p. 122). 



j 2003. M. alpestris F. W. Schmidt (=M. sylvatica Hoffm., var. yS alpesiris 

 JKoch). (Herm. Muller, ' Alpenblumen,' pp. 259-60.) The fragrant flowers of this 

 Alpine species are commonly of a more vivid and darker blue than those of lowland 

 species, though paler blossoms also occur as well as small- and large-flowered stocks. 

 (Cy. Fig. 278.) Their mechanism agrees with that of M. sylvatica. Crossing by 

 insect-visits is favoured, but should these fail automatic self-pollination takes place. 

 Magnus observed a variety with an excessive number of flowers, and as this remained 

 constant under cultivation continuous autogamy was inferred.
