Restio : quem dissertatione botanica ... præside Carol. Pet. Thunberg ...
This is a botanical dissertation on Restionaceae, a family of rush-like plants, presented under the supervision of Carl Peter Thunberg and printed at Uppsala, Sweden, in 1788 for academic examination. The single plate shows tall, slender stems rising from a baseline, some topped with clustered branching heads and others with fine feathery tufts. A designer could take from it the rhythm of vertical lines and the delicate, spare linework of an eighteenth-century scientific engraving.
