sterile parts of the spadices purple mottled at the tip, with a 

 solid band of purple just above the middle, and with a slight 

 purple spotting below, extending from the purple band to the 

 base of the sterile stalks. Both inflorescences were carpellate on 

 the main part of the spadix with purple stigmas; and on the 

 stalks of the sterile tips, a little way above the carpellate inflor- 

 escence, both had four purple-anthered staminate flowers! 

 There was a slight difference between the two inflorescences in 

 that one had a small, additional staminate flower in the top of 

 the carpellate part, in addition to the four staminate flowers 

 further up. 



7. A pair of separated twins with green sterile tips but 

 with their short stalks above the flower-bearing part slightly 

 purple mottled. The spathes had green tips with purple stripes 

 on their sheaths below. Both plants were robust. One was 12 in. 

 tall to the top of the sterile spadix and the other was 11 in. 

 Both were pure carpellate. 



8. A pair of twins still united on the same corm. They were 

 remarkably alike but one was slightly taller than the other, 

 measuring l}/2 in. while the other measured 73^ in. Both had 

 the sterile spadices or tips expanding decidedly toward the 

 base. The tips were purple mottled while the bases were pure 

 green. The spathes were greenish on the outside ; but each had 

 a broad band of purple on the inner side, one on the right side 

 and the other on the left . The opposite sides of the spathes had 

 a narrower purple mottled band, while the center of each was 

 green slightly mottled with purple. The spathes, therefore, 

 showed a decided right and left symmetry. The sheaths of the 

 spathes were both folded clockwise, but this is a fluctuating 

 character. Both inflorescences were pure staminate. 



9. A pair of twins which developed in the writers exper- 

 imental plots. The original plant was a pure carpellate individ- 

 ual brought in from the woods with others for experiments on 

 sex reversal. This individual was treated for reversal to the 

 male state by having its root system and leaves greatly reduced 

 and being kept in a comparatively dry condition. The following 

 year the growing bud showed that dichotomy had taken place, 

 as the corm developed twin shoots. Both branches were pure 

 staminate, being completely reversed in sex, along with a sim- 

 ilar change in most of the other individuals in the plot that had 

 been treated in the same way. The twins were of equal size and
