1903] MITOSIS IN PELLEIA 51 
PLATE XIV. 
(Figs. 27-29, second mitosis in the germinating spore.) 
Fic. 21. Cap more prominent at upper pole ; nuclear membrane intact. 
F1G. 22, Nuclear membrane has broken down at the poles, but is still 
intact at the sides of the nucleus. 
Fig. 23. Tripolar figure. 
FIGS. 24, 25. Lower cap much broader than the upper; the granular 
matter within the nucleus is derived largely from the nucleolus and stains 
with gentian violet. 
Fic. 26. Late prophase; the achromatic figure evidently consists of two 
half-spindles. 
Fig. 27. Spindle very broad at the poles; a rather common form at this 
stage in the first three mitoses; no radiations or centrospheres. 
Fic. 28. The caps have kept the ends of the spindle rounded for an 
unusually long period; no centrospheres or radiations. 
Fig. 29. Telophase; radiations, but no centrospheres have reappeared.
