Sometimes they become enlarged, as in the Sweet-potato, Dahlia, etc., and thus serve as reservoirs of plant food. They are then said to be tuberous (Fig. 7). In grasses and many other plants they are numerous and thread-like, and are called fibrous roots (Fig. 8). 11. Secondary roots may arise from the different parts of the plant,âstem and branches,âwhether above or below ground. They are called adventitious roots. They are common in creep- ing plants especially at the Ks-a-w m,i vu'iirA kxni joints, and their production â f'mS.'^^ k'^-'-Af K/'v.^ is favored by contact with moist soil.
