Explanation of Plate 2 

 Fig, 11 — Reinschosp07'a; 11a, axial (longitudinal) plan ; lib, equatorial (transverse) plan , p. 52 



12 — Alisporites ; axial (longitudinal) plan not shown; much the same as 16h but body 



wall thinner p. 48 



13 — Florinites; 13a, axial (longitudinal) plan, proximal side up; 13b, equatorial (trans- 

 verse) plan. The body tends to be slightly elliptical, the long dimension agreeing with 

 that of the bladder p. 56 



14 — Endosporites; 14a, axial (longitudinal) plan; it is difficult to judge whether the bladder 

 and body wall always join distally as shown here; 14b, equatorial (transverse) 

 plan p. 44 



15 — Pf^j'o^/'on^^^; pollen grains of modern aspect ; 15a, axial (longitudinal) plan in the 

 plane corresponding with the sulcus between the bladders ; 15b, axial (longitu- 

 dinal) plan in the plane of the bladders . p. 27 



16 — Parasporites ; 16a, equatorial (transverse) plan; 16b, axial (longitudinal) plan . . p. 42 



17 — Mono/^^^^; i/a, equatorial (transverse) plan; 17b, axial plan view corresponding to the 

 short dimension, distal grooves down, proximal suture up ; 17c, axial plan view cor- 

 responding to the long dimension p. 38
