Fig. 24. 26. A plant with long-petioled leaves and with 

 stemmed sepals and petals, one of the latter of which is shorter- 

 stemmed and smaller-bladed than the other two. Two stamens 

 are aborted and the rest vary in the length of their filaments and 

 anthers. 



145. A plant with two flowers scapes, one of which has the 

 leaves reduced to spurs at the tip of the rootstock while the other 

 has well developed petioled leaves placed 40 mm. above the root- 

 stock. In both flowers the sepals are sessile and the petals short- 

 stemmed. 



144. A two-stemmed plant in which one stem is long and 

 bears short-petioled leaves and a flower having both sepals and 

 petals sessile and the petals entirely white. The other stem is 

 short and bears long-petioled leaves and a flower with sessile 

 sepals and short-stemmed petals, one of which has a green centre 

 stripe while the other two are green proximally and white 

 distally. 



Fig. 25. 142. A two-stemmed plant, each stem bearing 

 petioled leaves and green-marked flowers, each with sessile 

 sepals and short-stemmed petals. 



143. A two-stemmed plant, one stem of which is short and 

 bears long-petioled leaves and a flower with sessile sepals and 

 petals, one of which is entirely white, while the other two have 

 green centre stripes. The other stem is long and bears shorter- 

 petioled leaves and a flower with sessile sepals and petals, each 

 petal being marked with a green centre stripe.
