Alstroemeria,
Gypsophila and an unidentified plant, neither with monogram nor signed, probably about 1865 Images in private property and catalogue descriptions of oil paintings and botanical drawings inform us of his oeuvre as a botanical artist. Heritage institutions which have Gaykema's work in their collections are
Naturalis Biodiversity Center in Leiden, the
Teylers Museum in Haarlem and the
Gelders Archief in Arnhem.
Illustrations for Kruidkunde In 1839-1842 Gaykema made a series of botanical drawings for the scientific survey work on the
botany and
zoology of the
Dutch East Indies, published as
Verhandelingen over de natuurlijke geschiedenis der Nederlandsche overzeesche bezittingen by the
Natuurkundige Commissie voor Nederlands-Indië (Natural Sciences Commission for the Dutch East Indies). The volume
Kruidkunde, written by
Pieter Willem Korthals, contains illustrations of more than fifty, until then in
Europe still unknown plants, for which Gaykema made the mostly
watercolored drawings. Both the original drawings and hand-coloured copies of the
lithographs are part of the collections of Naturalis, which donated images to the Dutch heritage web portal
Het Geheugen van Nederland and
Wikimedia Commons.
Illustrations for Annales Fifteen years later, in 1859, Jan Gaykema was able to become the main illustrator of the new international magazine ''Annales d'horticulture et de botanique, ou Flore des jardins du royaume des Pays-Bas, et histoire des plantes cultivées et ornementales les plus intéressantes des possessions néerlandaises aux Indes orientales, en Amérique et du Japon''. This was a publication of the
Koninklijke Nederlandsche Maatschappij tot Aanmoediging van den Tuinbouw (Royal Dutch Horticultural Society), edited by professor
Willem Hendrik de Vriese, the famous collector of Japanese plants nobleman dr
Philipp Franz Balthasar von Siebold, and university
head gardener Heinrich Witte. In its short period of existence Gaykema - whether or not he drew them from life in the Leiden
Hortus Botanicus - made nearly thirty colored plant drawings, of which the
Ghent artist
Louis-Constantin Stroobant (1815-1874) made engravings on stone, which were printed in color with the latest techniques by the company of this
lithographer. The printed text was provided by the Leiden printing company
A.W. Sijthoff, which was still young at that time. After the death of professor De Vriese in 1862 the publication of the magazine was stopped. == Life’s end ==
