MEMOIRS OF THE NEW YORK BOTANICAL GARDEN.

10 cm. from the base. The pistillate flowers oc- 

 cupied a zone about 8 cm. long on the spadix, and 

 were flaccid and pale rose color. The staminate 

 flowers occupied a zone 7 cm. wide above them, 

 and were of a brownish hue. Both stamens and 

 pistils did not reach normal development and were 

 not capable of carrying out seed-formation. The 

 irregular club-shaped end of the spadix was hol- 

 low by reason of the central cavity of lysigenous 

 origin. The portion of the spadix above the flowers 

 was 50 cm. in length and became curved at matu- 

 rity while still turgid and firm. The spathe was 

 seen to be furnished with many stomata, which 

 were open when examined in water, and the guard 

 cells of which were richly loaded with starch. 

 Similarly developed and active stomata were found 

 on the epidermis of the scape. The characteristic 

 unpleasant odor of the plant was noticeable, but not 

 so strongly as in examples grown in light. 



The scape and the flower endured for a period 

 of about five weeks from the beginning of growth 

 and then quickly perished. Immediately a swell- 

 ing bud at one side of the base of the scape began 

 to increase in size very slowly. The corm was 

 allowed to go into a resting stage in May, 1901, 

 and again watered and given favorable cultural 

 conditions in September, 1901, but the slow in- 

 crease of the bud ceased and no leaf had been de- 

 veloped as late as May 27, 1902. This bud occu- 

 pied the position of the leaf, which ordinarily begins 

 growth after the maturity of the flower, and con- 

 temporaneously with the growth of the roots. The 

 growth of the roots in an etiolated specimen con- 

 tmued more or less freely during the entire period 

 after their first appearance. The corm was taken 

 from the soil on the last named date, and in addi- 

 tion to a great number of rudimentary buds
