-(). In some jtorenninl herbs, prostrate stems or Idanches 

 inidor ^Moiuitl are thickened with this store of nourishment for 

 their wiiolf l«'n<rth, makin/Lr stout Ifna/sfni'/i-M, us they arc called ; as 

 ill Sweet Kla^'. Solomon's Seal ( Fii:. 63), and Iris, or Klowcr-dc- 

 liUcc ( Fi^'. <J|). These are |iciennial, and ^'row on a little way 

 each year, dvinir olV as nnich behind after a wiiile ; ami the newer 

 iiarts eveiv vear s«mh1 out a new set of lihrons root<. The Imds

 or the sears or riiii.'s \\hich mark whei'c the oM leaves or scales 

 hav.' fallen or decayed awny, nil plainly show that rootstocks are 

 forms of stem, and not i-oots. The lai';:re round scars on th(! root- 

 stock of Sohmion's Seal, which ;rive the plant its name (from 

 their looi.iii^' like impressions of a seal), are the [ilaces from 

 which the stalk liearinij the leaves and flowers of each season 

 has fallen olV in autunni. Tiof. 63, <i, is the bud at the end, to

 tliemselves. Sometimes it occujties all tlu>-^ 

 leaf, as in ihe liouscleek (Fig. 65) and other 



llctliij plaufti. Hei'e tln' close ranks of the 

 thickened leaves are wholly a})ovo ground. 

 Sometimes the deposit is all in the lower 

 end of the leaf, and on the groinul, or \\n 

 derneath, as in common JSnIhs. 'Jake a 

 White Lily of the gardens, for examjde, in 

 the fall, or in spring })efore it sends up the 

 stalk of the sea.son (Fig. 66). From the 

 bottom of tlie bidb, roots descend into the 

 soil to absorb moistm^e and other matters 

 from it, while, above, it sends up leaves to digest and convert these matter..s into 

 real nourishment. As fast as it is made, thisnourishmentiscarried down to the hot-
