. Botany of the southern states. In two parts. Botany. Napiform root. Tap root. Fusiform root Fig. 34. of natural growth, being almost uniformly produced by cultiva- tion. (5.) The Fusiform Root, or Radix fusiformis /where the root tapers toward each extremity, as seen in the Radish, it is known by the above name. Fig. 32. (6.) The Napiform Root is that variety which is very large at the base, but tapers abruptly, as in the Turnip, Fig. 33. The three preceding varieties are generally called, in distinc- tion from the other varieties, simple roots, the most of the root being confined to the main axis, and sending off few small fibers. (7.) The Filiform Root consists of a single filament, and is the root of some floating plants, as the Lemna. (8.) Didymous Roots are those which produce a tubercle each year, and when the tubercle of one year arrives at nearly the dimensions of the one of the preceding year, they answer to the form indicated by the term applied to them ; that is, double or twin roots. The Orchis affords examples of this variety, Fig. 34. (9.) The Palmated Roots are such as differ from the preceding only in hav- ing the lobes divided, giving them somewhat the appearance of a hand. The Orchis affords examples of this variety. 68. The following varieties are generally classed as either stems or buds, but are, in common parlance, called roots, and we know of no disadvantage in complying with the popular arrangement by describing them under this Didymous roots. What is a fusiform root ? What a napiform ? A filiform ? Didymous ? Palmated ?—68. How are the remaining varieties classed ?.
