Blackcurrant Blackcurrant The blackcurrant or black currant ("Ribes nigrum") is a woody shrub in the family Grossulariaceae grown for its berries. It is native to temperate parts of central and northern Europe and northern Asia where it prefers damp fertile soils and is widely cultivated both commercially and domestically. It is winterhardy, but cold weather at flowering time during the spring reduces the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. The raw fruit is particularly rich in vitamin C and polyphenol phytochemicals.
Idiosoma nigrum Idiosoma nigrum Idiosoma nigrum, also called Black rugose trapdoor spider, occurs only in south-western Australia, in dry woodlands east of the Darling Scarp and north to Moore River. Females can reach a length of about 30mm, males about 18mm. "I. nigrum" digs burrows up to 32 cm deep. The species name is derived from Latin "Niger" "black". The Black Rugose Trapdoor Spider is adapted for life in semi-arid habitats. They live in burrows up to 32 cm deep. These spiders construct an arrangement of leaves and twigs radiating out from the burrow entrance to serve as remote sensing device -
