diagonalis
Fig. 2.61 a Distal face and ‘sulcus’. b Half distal view (a and b) sulcus clear, taeniae faint possess
micro-punctate structure. Ektexine intra-reticulate on sacci
Protohaploxypinus goraiensis (Potonie and Lele 1961; Hart 1964) (Fig. 2.61).
Occurrence: Upper Permian of Collie–Muja Basin. Frequent in the following
samples: D/201-212
, B/ 224-227
.
Description: Disaccate striatiti. Diploxylonoid sacci, often slightly smaller than
corpus. Corpus outline vaguely discernible. Cappa traversed by 4–6 striae bordering on wide taeniae, 8–16 µ wide and continuous, although not quite parallel.
Ektexine detached equatorially on proximal face and sub-equatorially on distal
face. Cappula sharply outlined, narrow, 5–10 µ wide. Nexine very thin, does not
fold under distal roots. Ektexine thicker than nexine, intra-punctate on attached
parts and intra-reticulate on sacci.
Dimensions: Total width: 70–100 µ; corpus diameter 50–84 (15 specimens
measured).
