stood. The species are subject to great variation in appearance, and to much diversity of opinion among 
those who profess to be best acquainted with them. A middle course has here been taken, by which the 
doubtful kinds have been omitted, and those which are recognized, if not defined, satisfactorily, are alone 
admitted. 
1042. Tiarella. From tiara, a particular kind of head-dress, a mitre, in allusion to the form of its capsule. 
Pretty little North American herbaceous plants, related to saxifrage, and easily cultivated in pots of light 
sandy peat and loam. 
1043. Mitella. A diminutive of initra, a mitre ; so named for the same reason as the last genus, which it 
altogether resembles in habit and constitution. 
1044. Gypsophila. From yv-^oi, chalk, and <pi>.iM, to love j most of the species delight in chalky districts.
