WU OF THE ROOT, 



away from the roots, which are then to be replanted 

 in their natural soil previously dried and silted. Af- 

 terwards they must be well watered. The bulb for 

 the following year has not at the flowering period be- 

 gun to throw out its fibres, for after that happens it 

 will not bear removal. Satyrium albidinn having, 

 as mentioned above, so many pairs of roots, the 

 growth of some of which is always going on, has hith- 

 erto not been found to survive transplantation at all. 



Iris tiiberosa, Sm. FL Grac. Sihth. t. 41, has a 

 root very analogous to these just described, but /. 

 jiorentina and /. germanica, ^.39 and 40 of the same 

 work, have more properly creeping roots, though so 

 thick and fleshy in their substance, and so slow in 

 their progress, that they are generally denominated 

 tuberous, 



6. Radix bulbosa. A Bulbous Root, properly so cal- 

 led, is either solid,/! 13, as in Crocus, Ixia, Gladio- 

 hiSy &:c. ; tunicate,/! 14, timicata, composed of con- 

 centric layers enveloping one another as in Allium ^ 

 the Onion tribe ; or scaly, f. 15, consisting of 

 fleshy scales connected only at their base, as in Lilium^ 

 the White or Orange Lily. The two latter kinds 

 have the closest analogy with leaf-buds. They are 

 reservoirs of the vital powers of the plant during the 

 season when those powers are torpid or latent, and in 

 order to perform the functions of roots, they first pro- 

 duce fibres, which are the actual roots. The strict 

 affinity between bulbs and buds appears from the 

 scaly buds formed on the stem of the Orange Lily, 

 Jjiliun} bulbijbrum, which fall to the ground, and.
