there may be as many as eight. In the cortical parenchyma 

 of the stem the chloroplasts are apparently of the ordinary 

 form, but a careful examination shows that they are all con- 

 nected, and are directly referable to the divisions of the primary 

 plastid in the young cell. In all cases the nucleus is in 

 contact with the chloroplast or group of chloroplasts (Fig. 264). 

 The character of the chloroplasts here has its nearest analogy 

 in Aftthoceros, where occasionally a division of the chloroplasts

The development of the sporangia is much like that of 

 Lycopodimn, and has been studied by Goebel ^ and Bower in
