Abstract
IN 1900, Prof. Seward showed, in a specimen found at Amrapara in the Rajmahal Hills, pinnate leaves resembling Ptilophyllum cutchense McCl. sp. organically attached to a cycadean stem of the Bucklandia type.1 A Williamsonia flower discovered near the same locality a few years ago by Mr. G. V. Hobson of the Indian Geological Survey, and kindly placed at my disposal for description, proves to have belonged to the same plant as the Bucklandia. The stele of the peduncle shows that the wood is compact, as in the Bucklandia, and the structure of the bracts is identical in every way with that of the rhomboid leaf-bases preserved round the stem, which I have compared at the British Museum with kind permission of the authorities. There is also complete identity in structure with certain fragments of a Williamsonia flower, associated with another Bucklandia stem from Amrapara, described by Dr. N. Bancroft.2 The flower is unisexual and ovulate; in structure it closely resembles W. scotica Sew., from the Jurassic of Sutherland.3
