African strain

African Africa W001

Copyright 1998-2012 Yoshiaki Yoneda

The seeds of this strain were collected in 1956 by Dr. Kazuo Furusato at Conakry, a town in Guinea at about lat. 10 degrees N of West Africa. The hypocotyl has a tinge of light red. The cotyledons are narrow and small, and the cotyledonary veins have a little reddish tinge. There are almost no epidermal hairs to the hypocotyls or to the cotyledonary petiole. The leaf is wide and big. The leaf has shallow splits taking the shape of a sandy beach. This is called the main wide lobe type. The plant is among the most vigorous. Very late blooming (middle to late September in Shizuoka-city). Generally, one or two flowers are observed per peduncle, but there can frequently be three or four flowers, to a maximum of five. The flower is extremely light blue and the flower tube is white. Light-brown epidermal hairs extend to the calyx.
