Evolutionary history of plants foliage consisted of fern-like fronds, although they were not closely related to ferns. The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage. They all bore ovules, but no cones, fruit or similar. While it is difficult to track the early evolution of seeds, the lineage of the seed ferns may be traced from the simple trimerophytes through homosporous Aneurophytes. This
Flowering Plants of Africa (1921-1939), Edwin Percy Phillips (1940-1944), Robert Allen Dyer (1945-1964) and L. E. W. Codd. Flowering Plants of Africa Flowering Plants of Africa is a series of illustrated botanical magazines akin to "Curtis's Botanical Magazine", initiated as Flowering Plants of South Africa by I. B. Pole-Evans in 1920. It is now published by the South African National Biodiversity Institute (SANBI) in Pretoria. The magazine depicts and describes flowering plants from Africa and its neighbouring islands. The first volumes were printed in England by L. Reeve & Co. These first illustrations were done in black and white by lithography, zinc plates later
