6. Bitten, (premorsa), where the principal réot 
appears as if a part of it were bitten off, as in devil’s 
bit, Scabiosa succisa, the larger plantain, Plantago 
MAO. | 
7. Branched, (ramosa), divided into many ramifi« 
cations, as in all trees and most plants. 
8. Fibrous, ( fbrosa), when the root consists of 3 
multitude of small fibres, as in most Grasses. 
9. ‘Tuberous, (tuberosa), when certain fleshy pro- 
tuberances called knobs, adhere to the root, as in 
the potatoe, Solanum zuberosum, Sagittaria sagittifolia, 
Brassica oleracea, Napobrassica, &c. Of this there 
- are the following kinds. 
a. Granulated, (granulata), when the knobs are 
formed like small tubercles, as in Saxifraga

b. Spherical, (g/obosa), when the knobs are 
large, and of a round, spherical shape, as 
in the radish, Raphanus sativus. 
ce. Turnip-shaped, (napiformis), where the knobs 
are round or longish, but run into a sharp 
point, as in the common turnip, Brassica 
rapa. 
d. Oblong, oblonga, where the knobs are large, 
and are more or less of a longish shape, as 
in the potatoe, Solanum tuberosum. | 
e. Hanging, (pendula), is like the preceding, 
only the long-shaped knobs hang by threads, 
or fibres, as in the Spiraea Llipendula. 
Ff. Hollow, (cava), when the long knobbed root, 
as soon as it attains its full growth, becomes 
hol.
