Inasmuch as this deciduous genus includes the Maples, the Sycamore, and the variegated Negundo, it is one of considerable value. The Japanese Maples described in Chapter 15., where some good varieties are named, are very popular, as the foliage is in many cases prettily cut as well as richly coloured. For Acer Negundo variegata see Chapter 15., for the Sycamore, Chapter 9. The best Japanese Maples are forms of Japonicum and palmatum, particularly of the latter. A. campestre is the common Maple. A. platanoides is the Norway Maple, and of the several varieties, Reitenbachii, Schwedleri and Walderseei are popular. A. Pseudo-Platanus is the Sycamore; there is a particularly beautiful variety of this named Prinz Handjery; the foliage is of an exquisite bronzy salmon shade in spring, and colours brilliantly in autumn; it is one of the most conspicuous objects in a border in spring; another good variety is Leopoldii. A. rubrum is the scarlet Maple. A. saccharinum is the Sugar Maple. A. dasycarpum is the Silver Maple. A. rubrum is the only one of the Maples which should be chosen for a damp site. A form of A. pictum has attracted some attention during recent years, and is offered by some nurserymen under the name of colchicum aureum. The golden tint of the foliage is noteworthy. Colchicum or Colchicum rubrum is simply a synonym of pictum. Carpinifolium is the Hornbeam-leaved Maple.
