are developed which intertwine, sometimes incorporating the 
primary filament. If the lateral branch divides, as it not infre- 
quently does, the two filaments thus formed coil up, and these 
with those that are subsequently produced from them intertwine 
(figs. 44, 45). During the early stages of development the cell 
walls are usually clearly distinguished, but as the bulbil grows 
they become more or less transparent and quite indistinct (figs. 45, 
46). At the stage represented in fig. 46 the whole bulbil is color- 
less, the cells containing a large number of oil globules, which con- 
dition continues until almost maturity, when they begin to turn 
brownish. The walls gradually become more pronounced, and on 
account of lateral pressure they assume a more definitely angular 
condition. As the bulbils increase in size they become more and 
more spherical, so that at maturity they have a clear cut, even 
margin. Text fig. 6 represents a group of these bulbils. Although 
they vary considerably in size, the general spherical form and even 
outline is maintained throughout. Sometimes elongated, irregular 
bulbils are formed when two primordia happen to be close together 
and fuse as they develop. These, however, are the exceptions, and 
the cause of their abnormal condition can usually be detccted. 
If the bulbils are produced rather sparingly or away from each 
other, they invariably become spherical.
