(fig. 17), which may send out other lateral branches near the first 
(fig. 19). This branch may also take part in the formation of the 
bulbil. The cells of these various branches increase in size and 
become well supplied with food material. From them short 
lateral branches are produced which either intertwine among each 
other, or if very short assume the form of new cells as if produced 
by a process of budding or gemmation. Fig. 20 shows the primor- 
dium of a bulbil in which the secondary branches are being pro- 
duced. These will eventually intertwine with each other in a more 
or less wormlike fashion, as shown in fig. 21, an immature bulbil 
44min diameter. The first lateral branches that twine around the 
primary filament may become localized, in which case the mature ~ 
bulbils will be somewhat spherical, as shown in fig. 22, which 
represents a bulbil 110 uw in diameter. More often, however, the 
spherical bulbils are produced in a slightly different way. Not 
infrequently a terminal branch coils up and winds back on itself, 
or it may divide dichotomously, both branches thus formed twining 
back on the main filament (fig. 18). A primordium of this sort 
develops in the same way as the one already described, by the 
intertwining of lateral branches. The mature bulbil, however, 
tends to be more spherical than that in which a lateral branch 
_twines about the primary filament. Occasionally several bulbils 
_ may be produced from the same filaments, as is indicated in fig. 24, 
which shows the bees of 3 bulbils at a, b, and c respectively.

merge into one, forming an elongated and more or less irregular 
bulbil (text fig. 1). Owing to the variation in the mode of develop- 
ment, a great diversity of form is produced. Text fig. 1 i BE |
