F. Leaves all (or nearly all) entire in margin ; spines absent, except 

 at the apex, which usually terminates in a spiny point. 



30. Var. laurifolia, Loudon, Arb. et Frut. Brit. ii. 507 (1838) ; Moore, in Gard. 

 Chron. ii. 812 (1874). 



Leaves narrowly elliptic or oblong-lanceolate, entire, flat, about 2 to 3 in. 

 long, and 1 in. broad ; rarely a few leaves are present bearing one or two spines. 

 This is known only as a male plant. 



Several variegated forms are known : 



Var. laurifolia sulphurea ; mottled green in the centre, with a broad band of 

 sulphur yellow along the margin. 



Var. laurifolia aurea, with a narrow bright golden yellow margin ; and 



Var. laurifolia aureo-picta, blotched in the centre with deep golden yellow. 



31. Var. marginata, Loudon, Arb. et Frut. Brit. ii. 507 (not Moore). 1 



Var. scotica, Moore, in Gard. Chron. ii. 812, fig. 164 (1874). 



Leaves obovate or oblong, rounded and spineless, or with a slight cuspidate spine 

 at the apex, 2 to 2\ in. long, 1 to 1^ in. broad ; margin entire, undulate, strongly 

 thickened ; upper surface often marked near the apex with a cup-like depression. 



This peculiar holly, which is occasionally cultivated under the erroneous name 

 /. Dahoon? is now generally named var. scotica, but seems to be without doubt the 

 plant appropriately called var. marginata by Loudon. It is considered by Dallimore 

 to have arisen as a branch sport from var. crispa, and often shows leaves approaching 

 in character those of the latter variety ; but in opposition to this view may be 

 mentioned the fact that var. marginata is always female, while var. crispa is a 

 staminate form. 



Two variegated forms occur, which are known as : 



Var. scotica aureo-picta, a handsome variety which originated in the Cheshunt 

 Nursery ; it has leaves variegated with golden yellow in the centre ; and 



Var. scotica aurea, a dwarf form, having leaves with a broad golden edge. 



32. Var. crispa, Loudon, Arb. et Frut. Brit. ii. 507 (1838). 



Var. calamistrata, revoluta, and contorta, Goeppert, in Gartcnflora, iii. 319 (1854). 

 Var. tortuosa, Waterer, ex Moore, in Gard. Chron. ii. 812, fig. 164 (1874). 

 Var. marginata, Moore, in Gard. Chron. ii. 812, fig. 164 (1874) (not Loudon). 



Leaves spirally twisted and variously folded, about 2 in. long and 1 in. broad, 

 shining green ; margin much thickened, undulate, entire, or with one or two errati- 

 cally placed spines ; apex rounded or prolonged into a long stout decurved spine. 



This variety, which is called the Screw-leaved Holly, is always a male tree, and 

 is supposed by Dallimore to be a branch sport of var. echinata, as it occasionally 

 bears leaves like those of the latter in having spines on the upper surface. 



Var. crispa aureo-picta has leaves variegated with gold blotches. It often 

 produces branches with green leaves, and occasionally has leaves with superficial 

 spines. 



1 Var. marginata, Moore, is var. crispa, Loudon. 



2 /. Dahoon, Walter, is a native of the southern United States, and is apparently now not in cultivation. It was killed 

 at Kew in the great frost of 1895. Cf. Kew Bull. 1896, p. 10.
