Acer 643 



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, Carri^re. 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. iernatum, 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. euckloruvt, 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. Rafinesquianum, 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. meiallicum, 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. 



Loudon named this variety flava-variegata, variegated with yellow, which is
