Total forks in one half an arm (right side) 1,024 

 Astrophyton costosum (see plate 4) table to exhibit the number of forks in one stem (one half an arm). Thus, the 2d fork of the arm on the right 

 side of this right hand stem has, in its development, 253 forks, included between the 2d and 22d forks, counted from the disk, namely, 1 of the 2d 

 and 3d order, 2 of the 4th, 8 of the 5th, and so on. The total forks of the main stem and of its branches, on the right and left, being 1,024. The 

 entire number of forks for the five arms would be 10,245 (in the same proportion), and the number of terminal twigs 10,250.
