Lindsay, sp. We require more information as to the occurrence 

 of this plant before deciding definitely whether it is an introduced 

 or indigenous species, for, being the common Forget-Me-Not, it is 

 frequently cultivated in garden patches, and has obviously a 

 great capacity for spreading in suitable situations. 



M. pulustris extends through Europe to the Altai, where it is 

 noticed by Regel and Herder ; it appears, however, to be more 

 Southern in distribution than M. ccrspltosa. 



M. coespltosd, Schultz. Stem nearly a foot high; usually 

 simple, erect and straight from a short decumbent base, or only 

 very slightly creeping ; round, wiry, without wings or angles, but 

 with a narrow furrow or " impressed line " running down from 

 the margins of the leaves; smoothish-looking throughout and 

 shining, especially in dried specimens, but the surface is beset 

 with very short, appressed, conspicuous, bristly hairs. Lower 

 leaves stalked ; upper ones sessile ; all more or less spathulate ; 

 broader above the middle, and rounded or blunt at the tips ; the 

 veins, especially towards the base, of a reddish color, with which 

 the whole plant is frequently tinged. Flower small; pale sky- 

 blue, (half the size of that of M. palustris, and paler in colour;) 

 limb of corolla nearly horizontal, but. slightly incurved, and equal 

 in length to the tube. Calyx covered with appressed bristles. 

 Flowers in June or July ; one set of cymes is produced, and there 

 is no prolonged succession of blossoms as in M. palustris.

Ditches, drains and other moist places ; usually in gravelly or 

 stony soil. Quite common in Halifax County, N.S., as in railway 

 drains between Bedford and Windsor Junction, roadsides at 

 Sackville, Prince's Lodge, &c. Probably common throughout 

 the Dominion. 1 have collected it at Kingston. Dr. P. W. 

 Maclagau notes it at Chippewa and Thorold, Ont., and Mr. 

 Macoun finds it very common about Belleville. It is common in
