8 HOOTS. 



autumn, and the other is reserved for the following season, while 

 in the mean time a third is produced to succeed the latter/' 



Smith. 



3. Fasicular, (fasicularis.} PI. 1, fig. 8. When 

 a large portion of tubers proceed from a common ren- 

 tre shooting forth in an elongated form, as in Peony. 



Observation* 1. The radicles of tubers originate principally 

 from the stalks and the place of their insert ion. 



2. Tubers are reservoirs of nourishment, moisture, and vital 

 energy. 



3. In most cases a tuber is produced o ie season, lives through 

 the succeeding winter, and dies the next, after having produced 

 the plant und another tuber or parcel of tubers to 'succeed ,t. 

 Thus the herbage is annual, and the root, strictly speaking-, bienr 

 ninly but ns it annually reproduces itself and thus is tx-rpetuated, 

 it is termed p?rerti.inh Ex Pctatoe, (Solatium tiibero&um ) 



4. The knobs of genuine tuberous roots, such as ti.e polatre, ?ire 

 studded with buds, in which respect such roots differ esst nti ,lly 

 from bulbous ones ; which last are themselves simple buds and 

 produce their shoots as well as their offsets, either from the cen- 

 tre or from the base. 



All perennial roots, which have annual herbage, have buds. The 

 buds in bulbous roots are in the centre, as they ave also in many 

 of the spindle-shaped roots In the creeping root they are at its 

 ends ; in the tuberous, as has just been observed, scattered over 

 its surface. 



6. BULBOUS, (bblbos(i) a fleshy root of a bulbous or 

 globular form. 



Species of the Bulbous Hoot. 



1. Solid, (so/i(/.) PI. 1fi. 9. Of a uniform sub- 

 stance. Ex. Crocus and Tulip. 



%. Tunicate, (turncdta.) PI. 1 5 fig. 10. Compos- 

 ed of concentric layers enveloping one another. Ex. 

 Oniqii, Jttiiinn. 



3. Scaly, (sqwmmik) PL 1, fig* 11> Consisting 

 of fleshy scales connected only at their base. Ex. 

 While Lily. 



Observation 1. The two latter kinds have a very close analogy 

 with leaf buds They are the reservoirs of the vital powers of the 

 plant during the winter season. They as well as buds contain, in
