Macoto Murayama and T rep

T rep. The short form given by our field survey teams to white clover Trifolium repens. Still a common plant of pasture and waysides, so common that the intricacies of its structure and lf_noim_macoto1_gki1_350function generally go unnoticed.

Yet the mathematical artworks by Macoto Murayama shown in July at Dundee University reveal these intricacies in astonishing detail (image right).

The exhibition was held by courtesy of Frantic Gallery, Tokyo.

The Living Field’s correspondent gk-images sent some cellphone snaps from the exhibition. 

The introduction gives some detail of the artist and how he transfers the complex flowering heads and flowers of his botanical subjects to two-dimentional images.

“Macoto Murayama is a Japanese artist who cultivates ‘inorganic flora’. His extraordinary images are created after minutely dissecting real flowers and studying [them] under a microscope. His lf_noim_mctmryt_gki3_350drawings are then modelled in 3D imaging software then rendered into 2D compositions on photoshop before being printed on a large scale.”

Born in Kanagawa, Japan in 1984 he is now a researcher at Institute of Advanced Media and Art and Sciences, Tokyo.

The photographs, with reflections of lights and the opposite wall are of white clover (top) and spanish broom (lower).

Ps Back to T. rep. There would be, in the 1940s, five or six legumes growing as ‘weeds’ in cornfields but they have since been ousted by nitrogen fertiliser and chemical herbicide. Trifolium repens is one of the the last remaining of these nitrogen fixers still found, but then rarely, in arable fields.

 

Fixers 1 Coastal legumes

First in a series on nitrogen fixing legume plants.

Legumes are a group of plants that ‘fix’ nitrogen gas from the air to make proteins that are essential for growth and survival. When legume tissue dies, the nitrogen (N) is returned to the soil.

Legumes have many uses to people as food, medicinals and dyes. They also support insects that in turn  carry out ecological functions such as scavenging and pollination.

Here we begin a short series on wild N-fixers. First are those that live by the eastern shores of Angus.

The east coast of Angus (middle image) is rich in wild legumes. Those shown here live just above the beach or on top of the cliffs, where the vegetation is short and there are no bigger plants to out-shade them. Top left is a patch of purple milk-vetch Astragalus danicus and white clover Trifolium repens behind, top right kidney vetch Anthyllis vulneraria with litter, and ( bottom) flowering heads of kidney vetch (left)  and purple milk vetch.

Nearby were patches of meadow vetchling Lathyrus pratensis, bird’s-foot-trefoils Lotus species, and on the cliff-tops bush vetch Vicia septum, gorse or whin Ulex europaeus, broom Cytisus scoparius and the introduced laburnum Laburnum anagyroides.

One reason for the presence of legumes here is an unfarmed  habitat, low in nitrogen. Fixation by the legumes is one of the main routes by which the plants and soils get their essential nitrogen.

Most of these wild legumes have been tried over the last few thousand years as crops or forages. Some such as kidney vetch have been well-know medicinals (a vulnerary is a herb for treating wounds). Few have remained useful to agriculture, perhaps the best known being white clover, still cultivated today to enrich grass fields with fixed nitrogen.

Legumes are of the pea family Fabaceae, previous known as Leguminosae.
