enumerated by Pax and von Schwerin;! but many of these show only trifling variations, often inconstant in character; and only the most important varieties will be mentioned here :—
1. Var. pyramidale, Nicholson.? Pyramidal in habit with ordinary foliage ; originated in a row of trees, close to the gate of Roger, M‘Clelland and Co.'s Nursery, Newry.
2. Var. erythrocarpum, Carrière, Fruits red in colour and abundant, producing a fine effect in autumn. This variety is said to have originated in M. Ferrand’s nursery at Cognac; but according to von Schwerin is of common occurrence in the wild state in the Bavarian Alps.
3. Var. palmatifidum,? Duhamel. Leaves deeply cut, being five-partite.
4. Var. ternatum, von Schwerin. Leaves tri-partite to the base, so that they are ternate or nearly so.
5. Var. vitifolium, Tausch. Leaves large, deeply cordate at the base, with three broad rounded lobes, the basal lobes being very small or obsolete.
6. Var. clausum, von Schwerin. Leaves deeply cordate, with the sinus closed by the overlapping of the basal lobes.
7. Var. crispum, von Schwerin. Leaves wrinkled in margin. Forms also occur in which the leaves are rolled either backwards or inwards from the margin.
8. Var. cruciatum, von Schwerin. Leaves three-lobed, the lateral lobes being exactly at right angles to the median lobe.
9. Var. jaspideum, von Schwerin. Bark yellowish; leaves of the ordinary form.
10. Var. euchlorum, Nicholson.’ Leaves deep-green above, normal in shape. This variety originated in Spath’s nursery at Berlin.
11. Var. splendens, von Schwerin. Leaves red at the time of opening, after- wards becoming green. This includes var. Raffinesquianum, Nicholson, in which the young leaves are blood-red; var. cupreum, Behnsch, in which they are copper- red at the time of opening ; and var. metallicum, von Schwerin, with the leaves at first yellowish, afterwards copper-coloured, and ultimately green.
12. Var. albo-variegatum, Loudon. Stripe-leaved sycamore. Leaves splashed and marked with white. This variety is mentioned in the London Catalogue of Trees, published in 1730, which states that it comes true from seed. It often grows to a large size, a tree at Highmore Hall, Oxfordshire, the seat of G. T. Inman, Esq., being 72 feet high by 9 feet in girth.
13. Var. corstorphinense, von Schwerin.* Corstorphine or Golden Sycamore. Leaves often three-lobed, coming out yellow in spring, and in some places appearing about a fortnight earlier than those of the ordinary form. The colour is a fine golden one, and usually lasts till summer is advanced.
