112 OF THE ROOT, 



roots. The strict affinity between bulbs and 

 buds appears from the scaly buds formed 

 on the stem of the Orange Lil} r , Lilium 

 bulbiferum, which fall to the ground, and, 

 throwing out fibres from their base, be- 

 come bulbous roots*. The same thing 

 happens in Dent aria bidbifera, Engl. 

 Bot. t. 309, and Saxifraga cernua, t. 664. 

 These two last-mentioned plants however 

 have scaly roots, like the Toothwort, Lath- 

 rcea Sqaamaria, 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 flowering they are 

 scattered by the winds to a great distance, 

 as happens to our own Poa bulbosa, Engl. 



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

 stalk of LachenaUa tricolor. Curt. Mag. i. 82, whilst 

 lying for many weeks between papers to dry, which, 

 on being put into the ground, have become perfect 

 plants, though of slow growth.
