PHILOSOPHICAL NOTES ON 



(c), and within those again the growing point (d) ; the radicle (r) 

 is nothing hut a continuation of what is called the stem. But 

 the latter character belongs to the axillary and marginal buds also, 

 for we have the axillary buds of the lily and Asplcm?f?n decussattim 

 (Fjg. 42) and others giving off radicles. The marginal buds of 

 BryophyUnm ccdycmum do the same. 



If position alone were enough to warrant a distinction between 

 the bud and the ovule, then Ave ought logically to make a 

 distinction also between the axillary and the root-bud. 



Farther, if we turn to the ovule of Hippnris vidgaris 

 (Fig. 98), we shall find (that is, as I see it) that it appears to be 



Fig. 98. Hermaphrodite flower of Hippuris imlgaris: (a) stamen, 

 (6) stigma, (c) anatropous ovule, (e, e) bud-scales. The left-hand Fig. is 

 an enlargement of the right-hand Fig. (Sachs' " Text -hook "). 



nothing more than a branch bud* emerging from the petiole (c?), 

 and having a circinate vernation, exactly like the frond bud 

 emerging from the petiole of Aspidium filix mas (Fig. 101), and 

 of Pteris aquilina (Figs. 99 and 100). 



* The axillary bud, as I have been trying to show, is al$o a branchlet of 

 the leaf petiole, become adnate to the stem.
