Tiliacece Tilia. 8 5 



valvate. Petals 5, often with a scale at the base. Stamens 

 numerous. Ovary 5-celled. Fruit globose, nut-like, indehi- 

 scent; 1- or 2-seeded; seeds albuminous. About eight species, 

 from the temperate region of the northern hemisphere. The 

 Latin name of this genus. The Lime-tree, or Linden, in its 

 numerous variations forms one of our handsomest ornamental 

 trees. The Kussian bast is from the bark of the Lime-tree. 



1. T. Europcea. Lime-tree. This, in its ordinary form, is 

 a stately tree 60 to 100 feet high ; but the varieties of it 

 differ greatly in stature and size and form of leaf, and presence 

 or absence of pubescence on the leaves and fruits. Many of 

 these forms have been described as species, though they are 

 now usually ranged under this name. The common native 

 variety is parvifolia a small tree with small glabrous leaves 

 and hairy fruits. The one commonly planted is called grandi- 

 folia, and has large leaves which are downy beneath and ribbed 

 fruits ; and there is a handsome weeping variety of this. The 

 variety laciniata has lobed leaves, and coralllna (or rubra) 

 bright red twigs this is a very handsome variety ; aurea has 

 golden-yellow twigs, and there are several other varieties of 

 more or less merit. 



2. T. argentea, syn. T. tomentosa and T. alba (not of Michaux). 

 The bark of this species is greyish white, and the leaves are 

 clothed with a silvery pubescence beneath. It blooms later 

 than the common one, and retains its leaves later in Autumn. 

 This is a native of South-eastern Europe and Asia Minor, 

 now tolerably abundant in this country, and one of the hand- 

 somest in cultivation. 



3. T. Americana, syn. T. Canadensis, T. nlgra, and T. 

 glabra. This is the commonest of the American species in 

 cultivation, being represented by several varieties. They may 

 be distinguished by their obliquely broadly cordate or truncate 

 deeply mucronately toothed glabrous leaves. There are several 

 names besides those above enumerated given to slight and 

 often inconstant varieties. One form has leaves a foot or more 

 long and proportionately broad. 



T. alba, T. heterophylla, and T. pubescens are the names of 

 other North American species, but the same names are em- 

 ployed for some varieties of the European species. 



The T. dasystyla of Loudon, or euchlora of Koch, if indeed 

 both authors had the same thing in view, is a handsome form 

 with dark green glabrous leaves except on the under side in 

 the angles of the principal nerves.
