These trees may be identified from their (1) Buds, (2) Leaves, 

 (3) Flowers, and (4) Fruits by means of the following analytical 

 tables, which follow no natural system, but are purely artificial 

 and merely intended to simplify identification by those who 

 have not yet studied Forest Botany : 



L IDENTIFICATION OF COMMON BROAD-LEAVED TREES 

 FROM THEIR BUDS. 



A. BUDS OPPOSITE, AND END-BUD MUCH LARGER THAN SIDE-BUDS. 



/. Only 1 or 2 bud-scales visible ; bud scales black ; twigs smooth, greyish- 

 green 1. ASH. 



//. Several bud-scales visible, arranged closely and compactly ; ttoigs thick 

 and stiff. 



1. Bud-scales brown and resinous; leaf -scar large and triangular, 



with vascular bundles well marked . 2. HORSE-CHESTNUT. 



2. Bud-scales yellowish-green, with dark-brown tips and margins ; 



leaf -scar well marked . . . . .3. SYCAMORE. 



3. Bud-scales pinkish or reddish-brown, sometimes greenish at base ; 



leaf-scar narrow . . . . .4. NORWAY MAPLE. 



B. BUDS ALTERNATE, IN TWO LONGITUDINAL ROWS, ON OPPOSITE SIDES OF 

 THE TWIG. 



L Buds pointed, pale brown, and often about 3 or 4 times as long as 

 broad ; tivigs slender and smooth. 



1. Buds circular in transverse section, jutting out from twig, and 



usually over ^ an inch long . . . . 5. BEECH. 



2. Buds slightly angular in transverse section, lying close to twig,
