23
Possible modifications of axillary shoots
Thorns or tendrils
24
Thorn-like epidermal growths
Prickles
25
Modified leaves to resemble spikes
Spines

Modified stems that grow underground
Rhizomes
27
Runners- modified above-ground stems that run horizontally
Stolons
28
Short, round modified underground stems composed of rings
Bulbs
29
