the conn (k), to the base of which is attached the lateral shoot bearing the flowers, 

 will be seen to be enclosed in a brown envelope (Fig. 537 h). Roots spring from 

 the base of this lateral shoot (/), while those of the old corm (w) are in a withered 

 condition. At the summit of the corm the remains or scar of a dead aerial shoot 

 will be seen (st). The lateral flowering shoot bears at its base three sheathing 

 leaves (s', s," I') not separated by elongated internodes. In the axil of the third of

these (I') is a bud (k") which will form the flowering shoot of the next season ; this 

 third leaf will develop a lamina and appear above ground in spring as the first 

 foliage leaf. A thickened internode (k') separates it from the two leaves (I") 

 situated higher up on the axis. Above them come the flowers (b, b'), which may 

 be four in number, and stand in the axils of reduced leaves ; by the arrest of the 

 growing point of the axis the flowers appear to be terminal. In spring the reserve 

 materials from the tuber (k) are absorbed and the old tuber is pushed aside by the 

 swollen internode (k"), which in its turn enlarges to form a new corm. The three
