parts of the bud. The epidermal cells were distinguishable 
at the middle of the outer leaf, which completely surrounds — 
the inner one and overlaps, but the inner one does not meet 
around the enclosed flower-bud, as is shown in fig. 23. This 
is the character of the bulb scales, the outer one overlapping 
at the edges, which in its altered growth have united so that 
there is formed a continuous layer of very starchy flesh, 
which varies in thickness from one-sixteenth to three-six- 
teenths of aninch. The inner leaf and the inner scale agree _ 
in only partially surrounding the parts within it, and eachis 
thinner than its outer fellow (fig. 18). 
A second section showed each of the anthers to be com- 
posed of four pollen chambers, united by a delicate structure. 
The partition between the two in each of the lateral pairs of | 
anther cells was thinner than that which separated these 
lateral pairs (fig. 24). In the later growth of the flower the 
thinner of these sets of partitions is broken through and thus 
each lateral pair becomes a single cavity forming “two-celled 
anthers” described in the manuals. In the center the three 
lobed style is seen in section. It shows the tube in each lobe | 
from the edge of the Jeaf itself (fig. 25). tt 
In the tenth section the union between the filaments an ; 
the midvein of the petals was clearly seen. The anthers 40 nF 
adhere to the filament for their whole length as one of the ] 
filaments dropped away from the anther cells in this section : 
An external bud, at the base of the bulb, contained 4 SiM5, 7
