Description. Fronds tri-pinnate, pinnae opposite or subopposite. Pinnules close set and joined by wing along rachis. Margins entire, lobed in basal pinnules. Venation: a single vein leaving the midrib, sometimes dichotomising thrice, but one of the veins resulting from the first dichotomy usually remaining undivided.
New Zealand Localities. Waikato Heads (British Museum of Natural History No. V 23276). Quail Flat B125/4, B166/69. Strongman Mine B52/5, B428/8.
This species was first described from the Upper Gondwana of India and has been recorded from the Liassic of Austria and the Jurassic of Antarctica (Halle, 1913: 24).
Age. Liassic to Lower Senonian. (Neocomian to Senonian in New Zealand.)
Specimens from Strongman Mine (Rewanui Formation) are similar in shape to Halle's specimen (loc. cit., Text-fig. 5). The fragments from Quail Flat are tentatively placed in C. ? lobata because they resemble in shape and venation the apical portions of C. ? lobata from Strongman Mine.
