Broomea ramosa
Broomea ramosa, Cookson and Eisenack, 1958
Originally (and now) Broomea, subsequently Pareodinia. Lentin and Williams (1976, p.144) retained this species in Broomea.
Holotype: Cookson and Eisenack, 1958, pl.6, fig.7
Locus typicus: Broome, W Australia
Stratum typicum: Middle-Late Jurassic
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Cookson and Eisenack, 1958, p. 41]:
Description:
Body elongate-oval with straight to convex sides narrowing slightly towards the antapical horn, broader basally at the place of origin of the antapical horns and divided into two unequal regions - a longer apical region and a shorter and apical region - by a shallow "girdle" indicated on the surface by two rather faint parallel straight lines; a somewhat hoof-shaped pylome is developed in the apical region of the same surface. The apical horn tapers gradually to a short, straight solid terminal point; the two antapical horns which are of unequal size become more or less completely divided longitudinally into a varying number of somewhat ragged, pointed filaments.
The membrane is granular, more coarsely so in the antapical region.
Dimensions:
Holotype - 214 x 38 µm; apical horn c.76 µm, larger antapical horn c.38 µm.
Range - 176-218 µm x 24-38 µm overall; apical horn 76-90 µm.

Notes:

Broomea ramosa Cookson and Eisenack, 1958, has an elongate body, with epicyst longer than hypocyst. The antapical horns are unequal and divided into branches. The phragma is granular.
Size: overall 176-218 µm long, 24-38 µm wide, apical horn 76-90 µm long.
