not so simple. In Fig. 1, A shows a cauline bundle, 4 8’, in which 
an outer portion is being separated to form the bundle of a stipe, 
as at C. Two lateral portions, between this and what remains, 
are deflected to roots at each side of the base of the stipe which 
originate at the same time, as at 77”. The divisions which re- 
main in the stem unite with similarly divided parts of adjoining
