Actinostrobus pyramidalis, Miq. 345 
Fig. 49. Two suspensors and embryo cells at a later stage, when the embryo cell has enlarged 
preparatory to its first division, x 360. Oct. 12. 
Fig. 50. End of suspensor and embryo, after the formation of the first (vertical) division wall, 
x 485. Nov. 1. 
Fig. 51. Transverse division in one of the four cells of the first-formed tier. No wall could be 
certainly identified between the two nuclei, but doubtless it would be visible at a slightly later stage, 
x 485. Nov. 1. 
Fig. 52. A much later stage, showing the formation of embryonal tubes from the embryo cells 
next to the suspensor. The suspensor nucleus is still quite conspicuous at this time. x 205.

PLATE XXVIII. 
Fig. 53. Microphotograph of a similar section to Fig. 15. x 150. Oct. 9. 
Fig. 54. Microphotograph showing a group of suspensors and embryos, about the same age as 
Fig. 49. The multinucleate prothallus cells can also be seen, x 150. Oct. 14. 
Fig. 55. Microphotograph of a similar stage to Fig. 50. x 450. Nov. 1. 
Fig. 56. Microphotograph of a later stage than Fig. 52. The embryonal tubes are now very 
conspicuous, x 150. Nov. 21.
