Lycospora pseudoannulata Kosanke, 1950 

 Plate 3, figure 18 



Lycospora cf. trigonoreticulata (Loose) 

 Potonie & Kremp, 1956 



The size range for Lycospora trigonoreti- 

 culata given by Potonie and Kremp (1956, p. 

 104) is 30 to 40 }i. The few specimens en- 

 countered in this study were about 28 /x in 

 diameter. 



Lycospora cf. subjuga Bhardwaj, 1957b 



Although the single specimen of Lycospora 

 cf. subjuga found in maceration 1122-Q has 

 apical papillae, it was assigned to this spe- 

 cies. No mention was made by Bhardwaj of 

 these structures, but the holotype illustrated 

 (Bhardwaj, 1957b, pi. 25, fig. 84) appears 

 to possess apical papillae. 



Lycospora sp. 1 

 Plate 3, figure 19 



The spores are radial, trilete, and subtri- 

 angular in outline. The rays are distinct and 

 extend to the margin of the spore coat. Lips 

 are well developed and about 1.5 /x wide on 

 either side of the commissure. A flattened 

 equatorial ridge, about 3 jjl wide, is present. 

 The surface of the spore coat is distinctly 

 granulose under oil immersion objective. The 

 exine is about 1 [i thick. 



Figured specimen. — Negative 5871; Trivoli 

 Cyclothem, maceration 1175-G, slide 18, co- 

 ordinates, 136.6 x 48.1; size, 26.9 by 25.6 xi. 

 This species was also found in maceration 

 1175-B. 



Lycospora sp. 2 

 Plate 3, figure 20 



The spore is radial, trilete, and roundly 

 triangular in outline. The rays, bordered by 

 narrow, elevated lips, are distinct and extend 

 to the spore margin. The flattened equatorial 

 ridge is about 6 /x wide. The spore coat is 

 ornamented with small coni, which are so 

 closely spaced that some areas appear punc- 

 tate. 



Lycospora sp. 3 

 Plate 3, figure 21 



The spore is radial, trilete, and roundly 

 triangular in outline. The rays are distinct, 

 straight, and about three-fourths the length 

 of the spore radius. Low, dark lips about 2 /x 

 wide are on either side of the commissure. 

 The surfaces of the body and flange, which 

 is about 3 /x wide, are levigate under oil im- 

 mersion objective. The body and flange are 

 about 1 /x thick. 



Figured specimen. — Negative 5781; Fith- 

 ian Cyclothem, maceration 1170-G, slide 4, 

 coordinates, 139.1 X 32.6; size, 39.9 by 

 38.6 /x (including flange) . 



Genus Microretigulatisporites (Knox) 



Potonie & Kremp, 1954 



Table 1 



Type species. — Microreticulatisporites lacu- 

 nosus (Ibrahim) Knox, 1950. 



Affinity. — Noeggerathiales? (Potonie and 

 Kremp, 1954, p. 143). 



Genus Pityosporites (Seward) 

 Potonie & Klaus, 1954 

 Type species. — Pityosporites antarcticus 

 Seward, 1914. 



Affinity. — Coniferae. Somewhat similar 

 to modern Podocarpaceae and Pinaceae 

 (Schopf, Wilson, and Bentall, 1944, p. 28). 



Pityosporites sp. 1 

 Plate 3, figure 22 



The prepollen grain is bilateral, bisaccate, 

 and has an elliptical body. The cap is distinct 

 and reticulate. Bladders are externally levi- 

 gate and internally coarsely reticulate. La- 

 cunae of the reticulations are up to 3 /x in 

 diameter. 



Figured specimen. — Negative 5798; Fithian 

 Cyclothem, maceration 1170-G, slide 19, co- 

 ordinates, 134.0 X 46.9; size, total length 

 67.7 /x, body 41.5 by 30.8 xi.
