straight : cotyledons plane, foliaceous. — Trees or shrubs, rarely

 pulated, often toothed. Flowers axillary. 



1. Tilia. Linn. Lime. 



Calyx 5-partite, deciduous. Petals 5, with or without a nectary 

 at the base. Fruit coriaceous, 5-celled, without valves, cells 

 1 — 5, 2-seeded. — Name of obscure origin.

1. T. europcea, Linn. Common Lime or Linden Tree. Nec- 

 taries none ; leaves twice the length of the footstalks, quite 

 glabrous, except a woolly tuft at the origin of each vein be- 

 neath; cymes many-flowered ; fruit coriaceous, downy. Br. Fl.

Woods and hedge rows, probably not indigenous. Fl July. 1? . — 

 A large handsome tree, its flowers yellowish-green, on a stalked cyme, 

 springing from a large lanceolate foliaceous bractea, which falls off 

 with the fructified cymes. Fruit generally one-celled and one-seeded. 

 There are fine specimens of this ornamental tree to be seen at the old 

 lime walk in Stillorgan Park. Sir James E. Smith states, that an an- 

 cient lime, of great magnitude, which grew where the ancestors of Lin- 

 naeus had long resided, is said to have given them their family name, 

 Linn being Swedish for a lime tree. The bark of this, and, perhaps, 

 some other species, makes the Russia garden-mats called bast. Bees 

 collect much honey from the flowers. 



2. T. parvifolia, Ehrh. Small-leaved Lime. Nectaries none ; 

 leaves smooth above, glaucous beneath, with scattered as well as 

 axillary hairy blotches ; umbels compound, many-flowered ; 

 fruit roundish, brittle, nearly glabrous. Br. Fl. 1. p. 259. E. 

 Fl. v. iii. p. 20. E. Bot. t. 1705.
