112 OF THE ROOT, 



roots. The strict affinity between bulbs and 

 buds appears from the scaiy buds formed 

 on the stem of the Orange Lil}', LiUiim 

 bulhiferiun^ which fall to the ground, and, 

 throwing out fibres from their base, be- 

 come bulbous roots*. The same thing 

 happens in Dentaria bidbifera, Engl. Bot. 

 t,309, and Saaifraga cerniia, t. 664. 



These two last-mentioned plants however 

 liave scaly roots, like the Toolhwort, IjG- 

 thraa Squamnriaj t. 50, which seem bulbs 

 lengthened out. Whether they would, in 

 the torpid season of the year, bear removal, 

 like bulbs, we have no information. If 

 disturbed at other times they are immedi- 

 ately killed. Many plants with solid bulbs 

 are provided by Nature to inhabit sandy 

 countries, over the face of which, in the dry 

 season succeeding]: their flowerino-, they are 

 scattered bv the winds to a o-reat distance, 

 as happens to our own Poa bulbosa, Engl. 



* I have had scaly buds form even on the flower- 

 stalk of Lachenalia tricolor, Curt. Mag. t. S2j whilst 

 lying for many weeks between papers to dry, whichj 

 on being put into the ground, have become perfect 

 plants, though of slow grov.th.
