Synopsis Ovules of Eurystoma trigona sp. nov. are described. Over 330 unpollinated ovules were found attached to a petrified megasporophyll which appears to be a juvenile form of Alcicornopteris Kidston. Each ovule is triangular in cross section and has three wing-like extensions of the integument. None shows a female prothallus. The possibility that Alcicornopteris represents the fertile foliage of Stenomyelon is discussed.

Synopsis Kochiproductus coronus sp. nov., a flanged buxtoniid from upper Viséan limestone of Ayrshire, Scotland, is described and a reconstruction attempted. The possible functions of the flange are discussed. Experiments carried out on a laminar flow table indicate that one effect of this structure would be to check the velocity of incoming feeding currents thus trapping sediment and dense particles on the lower flange but allowing the free inflow of food material.
