cultivation, and from which innumerable forms have been 

 developed, that differ either in habit, foliage, flowers, or 

 fruit. The deciduous calyx would seem to be the only 

 reliable distinguishing character. It is a widely-distributed 

 species, being found in North China and Japan, Siberia, 

 and the Himalayas, and has from time immemorial been 

 cultivated by the Chinese and Japanese, so that it is 

 not at all surprising that numbers of forms have been 

 developed. 



P. CARDINALIS (1893) is a desirable garden form, with 

 conspicuous cardinal-red flowers, which are freely produced. 

 It is a good town shrub. 



P. COEONABIA. Sweet Scented Crab. North America, 

 1724. This is a handsome species, with ovate, irregularly- 

 toothed leaves and pink and white fragrant flowers. The 

 flowers are individually large and corymbose, and are 

 succeeded by small green fruit. P. Coronaria flore-pleno 

 is a semi-double variety, that far surpasses the parent in 

 point of beauty. The flowers are reddish-white, half an 

 inch in diameter, and violet-scented. 



P. DOMESTICA (syn Sorbus domestica). True Service. 

 Britain. This resembles the Mountain Ash somewhat, 

 but the flowers are panicled, and the berries fewer, larger, 

 and pear-shaped. The flowers are conspicuous enough to 

 render the tree of value in ornamental planting. 



P. FLORIBUNDA (syns P. Mains floribunda and Mains 

 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. 

 Petersburg gardens many very ornamental Crabs have 

 been sent out, these differing considerably in colour of
