16 ON THE ORGANS OF PLANTS. 



and flowers on it. The Stem may become the Trunk 

 of a Tree, with numerous branches, as well as leaves 

 and flowers on it ; or it may be no bigger than the 

 Stem of the Anemone or Violet : if it have leaves on 

 it, it is a Stem. PI. I. d., II. A. 13. 



STALKS on which Flowers only grow, are called 

 PEDUNCLES ; PI. I. 4, e. f. g. h. If the Peduncle 

 bear smaller Stalks with Flowers on them, those stalks 

 are called PEDICILS. PI. I. 4. f. PI. II. 11. 12 E. P. 

 If the Flower-stalk rise immediately from the Crown 

 of the Boot, it is called a SCAPE. The LEAF-STALK 

 is called a PETIOLE, PI. I. 3. 0., PL II. 14. p., if the 

 Petiole bear smaller Stalks with Leaves on them, those 

 Stalks are called PETIOLULES. PL II. pp. 



LEAVES are formed of LAMINA, (the blade) with 

 nerves and veins. Sometimes the Petiole does not 

 terminate with a Leaf, but only the nerves (or midrib) 

 when it is called a TENDRIL. Each different form of 

 Leaf is distinguished by a different name or term, for 

 which I refer you to the Plates and Glossary. 



BRACTS, are little scaly Leaves which grow on the 

 Flower-stalks of some Plants. PL II. C. b. If these 

 Bracts are arranged in a Whorl round the Stem they 

 are called INVOLUCRE ; sometimes having the appear- 

 ance of Leaves, (as in the Anemone, PL II. A. I.)
