P. FLORIBUNDA (_syns P. Malus floribunda_ and _Malus microcarpa floribunda_).--China and Japan, 1818. The Japanese Crabs are wonderfully floriferous, the branches being in most instances wreathed with flowers that are individually not very large, and rarely exceeding an inch in diameter when fully expanded. Generally in the bud state the flowers are of a deep crimson, but this disappears as they become perfectly developed, and when a less striking tint of pinky-white is assumed. From the St. Petersburgh gardens many very ornamental Crabs have been sent out, these differing considerably in colour of bark, habit, and tint of flowers. They have all been referred to the above species. P. floribunda is a worthy form, and one of the most brilliant of spring-flowering trees. The long, slender shoots are thickly covered for almost their entire length with flowers that are rich crimson in the bud state, but paler when fully opened. There are numerous, very distinct varieties, such as P. floribunda atrosanguinea, with deep red flowers; P. floribunda Elise Rathe, of pendulous habit; P. floribunda John Downie, very beautiful in fruit; P. floribunda pendula, a semi-weeping variety; P. floribunda praecox, early-flowering; P. floribunda mitis, of small size; P. floribunda Halleana or Parkmanii, probably the most beautiful of all the forms; and P. floribunda Fairy Apple and P. floribunda Transcendant Crab, of interest on account of their showy fruit. P. floribunda Toringo (Toringo Crab) is a Japanese tree of small growth, with sharply cut, usually three-lobed, pubescent leaves, and small flowers. Fruit small, with deciduous calyx lobes. P. GERMANICA (_syn Mespilus germanica_).--Common Medlar. Europe (Britain), Asia Minor, Persia. Early records show that the Medlar was cultivated for its fruit as early as 1596. Some varieties are still grown for that purpose, and in that state the tree is not devoid of ornament. The large, white flowers are produced singly, but have a fine effect in their setting of long, lanceolate, finely-serrate leaves during May.
