MARICA. [Iridacese.] Warm greenhouse evergreen 

 herbaceous perennials, with very beautiful but ephemeral 

 flowers. Soil, loam and peat of open texture. Increased by 

 division, or by planting adventitious offshoots or cuttings.

MARJORAM. See Oeiganum.

MARTYNIA. [Pedaliace®.] Greenhouse or half-hardy 

 annuals, with a somewhat coarse habit and showy flowers. 

 The seeds should be sown in a hotbed in March, and the 

 young plants potted singly, and kept growing in heat near 

 the glass in the way Balsams are managed. As they grow 

 they must be shifted, and hardened ofT to bloom in a cool 

 stove or greenhouse or frame. M.fragrans, the best of the 

 species, will also succeed in a sheltered place, planted out for 

 the summer. They require rich light soil.

MATHIOLA. Stock. [Cruciferte.] A favourite genus 

 of hardy plants, among the sweetest and gayest of garden 

 flowers of which one familiar species, M. annua, the Ten- 

 week Stock, is an annual ; another, M. simpllclcauUs, the 

 Brompton or Giant Stock, is a biennial ; and M. incaua, the 

 Queen Stock, is a sub-shrubby kind, though best treated as a 

 biennial. The varieties of these, especially of the first, are 

 very numerous, and, as imported from Germany, very fine. Of 

 the ordinary hoary-leaved Ten-week or annual Stock there 

 are a score or more different colours, which the German seed- 

 growers save distinct. Of the Ten-week Stock having smooth 

 green or Wallflower-like leaves there are also many varieties 

 of colour ; and, besides these, there are variations of h.ibit 

 which have become perpetuated by careful seed-saving. The 

 biennial Stock, that is, those sown one year to bloom the 

 next, varies as much as the annual in regard to habit, but not 

 in respect to colour. The Brompton and the Queen Stock 

 are well-known distinctions in this class. When once posses-
