Intern odes. 



Nodes with leaf-scars. 



Two axillary buds. 



Terminal bud. 

 Fio. 1 (6). THE SAME. Showing the scars left by the fulling off of the bud-scales. These scars mark the 



commencement of a year's growth. 

 FIG. 2. BULB OF ONION. Showing 



Stem, short. 



Leaves, crowded, and stored with nutriment. 



Buds (1) terminal and (2) axillary. 



Roots, fibrous. 



The peculiarity of the Onion is this : it remains permanently in the bud condition. A 



permanent bud of that kind is called a bulb. 

 Fio. 3. Showing KINDS OF LEAVES 



Scale leaves. 



Foliage leaves the green leaves which manufacture starch (L. folium, the leaf). 



Bracts leaves near flowers (L. bractea, a thin plate). 



Floral leaves (L. fos, a flower). (Red.) 

 FIGS. 4, 5. EXAMPLES OF LEAVES 



Pinnate leaf, with elongated midrib (Pea). 



Palmate leaf, with extremely short midrib (Horse Chestnut). 



Compound leaf. The incisions extending into the midrib, and subdividing one leaf into a number 

 of leaflets. 



Stipules appendages originating from the base of leaf-stalk, not from the stem. 

 FIG. 6. Showing FOLIAGE LEAVES united or connate (L. con, together ; unfits, born).
