the second method cf cell division, the numter is consid- 

 erably grea-ter. The cell next below the apex ina,y show 30- 

 250 nuclei. 



Branched lia.irs are fretiiiently home on the upjier "bor- 

 ders of tlie younger cells. There are usually 6 or 7 of 

 these ra-ound each node on which they occur. 



Their mode of origin is very similar to that of the 

 tetrasr^oric file^ments to be described Iciter. Small papil- 

 lae arise nearly simultaneously around the upper border of 

 a cell near tlie cross partition (fig. ), each papilla con' 

 taining a single nucleus and dense, homogeneous cytoi'lasm. 

 The papillae are cut off from the protoplast by an arched 

 membrane (fig. ), similar to tha.t foi-med in the division 

 of some of the vegetative cells. The nucleus now divided 

 (fig, ), and one of the da,ugliter nuclei wa.nders into a 

 bud from the papilla, the bud, with its nucleus, now becom- 

 ing cut off (fig. ). A second, a third, and somelriimfes 

 a fourth bud are formed and cut off like the first (fig. 

 Each of these daughter cells behalves in the same way, cut- 

 ting off three or more buds, and in t]iis way a tlirice com- 

 poimd hair is formed (fig. 47). Plach of the terminal cells 

 divides into two. The basal cell of a hair becomes multi- 

 nucleate, as do the cells of the firr-t order of branching;
