posed of thin-walled cells of fairly uniform di- 
ameter in every direction, and often with con- 
spicuous intercellular spaces.

center.

ment in which an egg develops without fertiliza- 
tion.

pinnately divided, twice pinnate. 
Pinnule, one of the secondary divisions of a pin- 
nulately divided structure. 
Placenta, a more or less conspicuous structure 
serving as the place of origin and attachment for 
the gonimoblasts in the sporocarp of many 
Floridee. 
Plumose, featherlike or plumelike. 
Plurilocular, a term used for the reproductive 
organs of many Pheophycee which are divided 
by walls into numerous compartments, produc- 
ing a single motile reproductive cell in each 
compartment. 
Polychotomous, a method of branching in which the 
thallus is divided into many parts of more or less 
equal size. 
Polygonal, having many angles and many sides. 
Polysiphonous, consisting of several coherent lon- 
gitudinal rows of cells. 
Polyspores, many spores borne in one sporangium. 
Procarp, the complex female organ of many Flori-

auxiliary cells, and other accessory cells.
