AND ITS DIFFERENT KINDS. lUl 



throwin,^ out fibres from their base, become bulbous 

 roo-:-*. The same thing happens in Dentaria hid- 

 bifera, Engl. Bot. t. 309, and Saxifraga cernua, t. 

 664. 



These two last-mentioned plants however have 

 scaly roots, like the Toothwort, Lathrcea Squamaria^ 

 t. 50, which seem bulbs lengthened out. Whether 

 they would, in the torpid season of the year, bear re- 

 moval like bulbs, we have no information. If dis- 

 turbed at other times they are immediately killed. 

 Many plants with solid bulbs are provided by Nature 

 to inhabit sandy countries, over the face of v/hich, in 

 the dry season succeeding their flowering, they arc 

 scattered by the winds to a great distance, as happens 

 to our own Poa bidbosa^ Engl. Bot. t. 1071, as well 

 as to numerous beautiful productions of the Cape of 

 Good Hope. 



7. Radix articulata, or granulata,jl 16. A Jointed or 

 Granulated Root agrees very much with those de- 

 scribed in the last section. The Oxalis Acetosella, 

 Wood Sorrel, Engl. Bot. t. 762, and Saxifraga 

 granulata. White Saxifrage, t. 500, are instances of 

 it. The former has most affinity with scaly bulbs, 

 the latter with solid ones. 



It is evident that fleshy roots, whether of a tuberous 

 or bulbous nature, must, at all times, powerfully resist 



* I have had scaly buds form even on the flowerstalk of La- 

 ■:henalia tricolor, Curt. Mai^. t. 82, whilst lying for many weeks 

 between papers to dry, which, on being put into the ground, 

 liave become perfect plants, though of slow growth.
