1913] YAMANOUCHI—ZANARDINIA 33 
Fics. 36, 37.—Prophase: 44 chromosomes clearly shown; fig. 36 a sec- 
tion at right angles to long axis of sporeling similar to that shown in fig. 3%. 
Fics. 38, 39.—Metaphase: fig. 38 shows characteristic elongation of 
sporeling and thickening of elongated portion of cell wall, while in fig. 39 
elongation has not yet begun. 
1G. 40.—Metaphase viewed from pole: part of cell wall thickened, but 
no elongation of sporeling begun. 
Fic. 41.—Metaphase: cross section of sporeling perpendicular to axis of 
elongation; 44 chromosomes plainly visible at equatorial plate. 
IG. 42.—Anaphase. 
Fic. 43.—Telophase: although part of cell wall has thickened, no elonga- 
tion of sporeling has begun. 
Fic. 44.—Sporeling in 2-celled stage: nucleus in terminal cell in prophase, 
and that of basal cell in resting condition. 
Fic. 45.—Sporeling in 2-celled stage: nucleus in one cell in metaphase, 
showing 44 chromosomes; no thickening of cell wall has begun. 
1G. 46.—Sporeling in 2-celled stage: nucleus in terminal cell in late 
anaphase; basal cell elongated in two directions. 
Fic. 47.—Sporeling in 2-celled stage: nucleus in terminal cell in telophase. 
Fic. 48.—Sporeling in 2-celled stage: nucleus in basal cell in telophase. 
Fic. 49.—Sporeling in 2-celled stage: nucleus in terminal cell in anaphase 
and that of basal cell in metaphase. 
Germination of unfertilized female gamete 
Fic. 50,—Female gamete 36 hours after quiescence: cell wall does not 
Seem to be developed except at point where a slight elongation is noticeable, 
Fic. 51.—Female gamete 46 hours after quiescence: cell wall now recog- 
nizable, especially at elongated point; nucleus in resting condition. 
IG. 52.—Female gamete 48 hours after quiescence: nucleus with 22 
chromosomes in prophase. 
IG. 53.—Nucleus in metaphase: contour of sporeling almost spherical. 
Fic. 54.—Nucleus in late metaphase, laterally situated: cell wall does 
not seem to be well formed. 
Fic. 55.—Polar view of metaphase showing 22 chromosomes. 
Fic. 56.—Anaphase. 
Fic. 57.—Telophase: elongation of sporeling is remarkable. 
Fis. 58.—Sporeling in 2-celled stage: nucleus in terminal cell in resting 
condition and that of basal cell in prophase, showing 22 chromosomes. , 
1G. 59.—Sporeling in 2-celled stage: nucleus in terminal cell in prophase, 
showing 22 chromosomes. 
Fic. 60.—Sporeling in 2-celled stage: t 
Fic. 61.—Sporeling in 2-celled stage: nucleus in terminal cell in anaphase. 
Fic. 62, 6 3-—Sporelings in 3-celled stage: sporeling in fig. 62 has elongated, 
and that shown in fig. 63 is still about spherical,
