1894.] The Bulb of the Adder s- Tongue. 65 
a quarter of aninch long. The upper surface of the leaf was 
marked by a line extending partly across the sprout. 
On examining the bulbs a quarter ofan inch long, from the 
seeds of last spring’s flowers, the leaf was merely a round yel- 
lowish body having a line extending nearly across it, showing 
where the upper surface of the leaf was tobe. In a bulb half 
an inch long, the leaf is convolute and its surfaces are free 
from each other. In an intermediate bulb, the leaf was con- 
volute above and conduplicate near the base. 
On November 29th a large bulb was found which had a bud 
almost entirely separated from the parent bulb, and there was 
also a bud forming at one side which had the sprout well de- 
veloped but the line of separation was indicated only by a 
notch on one side. A similar bulb examined December 6th 
is shown in figs. 17 and 18.
