1896 | CYSTOCARP OF GRIFFITHSIA 47 
Fic. 5. A different view of a stage similar to that represented in fig. 4. 
Fig. 6. The branch lies under the vegetative cell. One of the peripheral 
cells has cut off a sterile cell. 
Fic. 7. The third peripheral cell has been cut off from the central cell. 
Fic. 8. Two peripheral cells have divided, and the supporting cell has 
produced the basal cell of the said se branch seb a c.). One peripheral cell 
has been severed from its mother c 
G. 9. The carpogenic aie now consists of two cells. The second 
so pe cell has no appendicular cell. 
G. 10. The entire fruiting branch lies above the corresponding vege- 
tative aia; The carpogenic branch has reached maturity, and the carpo- 
gonium is prolonged into the trichogyne. 
Fic. 11, An abnormal vegetative development from the supporting cell. 
Fic. 12. A pollinoid (f.) is attached to the trichogyne. Penultimate cell 
of the ae yee branch large and lying partially beneath the second cell. 
13. The trichogyne has disappeared, and the carpogonium and 
Peis cell have lost their contents and shrunken. The second cell of 
the carpogenic branch, as well as the basal cell, is rich in protoplasm. 
Fic. 14, The supporting cell and the central cell have abundant proto- 
plasm. The former has cut off the placental cell. The meaning of + is 
uncertain, its connection with any other ceil not being clearly made out. The 
involucral filaments have begun to develop. 
Fic. 15. The entire branch has increased in size. The carpogenic branch 
has become disorganized, the basal cell remaining attached to the supporting 
cell. Several lobes are arising from the placental cell, and are seen in differ- 
ent stages. Involucral threads omitted to avoid confusion. 
FiG. 16. A similar or slightly later stage than fig.1§. Involucral threads 
again omitted. 
Fic. 17, The young cystocarp inclosed in the involucre. Three of the 
Sides 48 fully grown; one is still small. 
Fic, 18, A slightly later stage with involucre omitted. 
FiG. 19. A still later stage. Fusion has apparently taken place between 
the placental cell, supporting cell, and central cell, and lobes are arising from 
the large fusion cell (7). Some of the spores are mature, and their connec- 
tions have been broken. Most of the sterile cells have disappeared, while 
Some seem to have developed abnormally.
