drier climate of our gardens. It will require a loose, peaty, 

 or sandy soil, careful shading from the midday sun, frequent 

 sprinkling with water, and to be covered with a glass in 

 hot dry weather. Under this treatment, a plant of it in my 

 garden has completely filled with its numerous stems a 

 square hand-glass, twenty inches to the side, and twenty- 

 four inches in depth ; and, apparently, it would have grown 

 larger, had space allowed the free development of the 

 lateral branches, which are much cramped by the glass. It 

 will bear some frost, but may likely prove more impatient 

 of cold than our native species of the Genus. In a Wardian 

 case it would probably succeed very well. 



Descr. Root fibrous. Stem thickly covered with hairs, 

 mostly bent back so as to point towards the root, decum- 

 bent at the base, rooting by succulent fibres, which arise 

 under the insertion of the lower leaves, and along the 

 angles extending downwards from their points of insertion. 

 Lateral branches numerous, and, like the principal stems, 

 terminating in several close racemes of flowers. The lower 

 portions of the stems apparently endure several years, be- 

 coming hard and somewhat woody, while the upper por- 

 tions die back yearly. Leaves very harsh, covered with 

 strong hairs, which, on the upper surface, point towards the 

 apex of the leaf; but on the under surface, especially along 

 the midrib, they are curved back so as to point towards the 

 insertion of the leaf. Lower leaves spathulate, oblong, 

 retuse at the extremity, horizontal, or inclined backwards. 

 Upper leaves more oblong, scarcely retuse, patent. Raceme 

 subsecund with numerous approximate flowers. Pedicels 

 erect or curved upwards, about the length of the calyx, 

 with nearly erect pubescence. Calyx deeply divided into 

 five linear, straight teeth, with long, erect, or erecto-patent 

 pubescence, open in fruit. Corolla about equal to that of 

 M. repensor sylvatica, deep indigo-blue, with a purple tinge 

 at first, and slightly burnished in the sun ; its lobes propor- 

 tionably broader than in the European species, obcordate 

 and emarginate; tube whitish, about equal to (in some 

 flowers, rather shorter than) the limb, contracted at base and 

 top, and nearly closed by the folds of the corolla. Fruit 

 quite smooth and shining. In general habit, coming near- 

 est to M. palustris, but abundantly different from all the 

 European species
