This is a wild strain from Cesar district in Colombia. The hypocotyl has a reddish tinge, and the cotyledonary veins are red, too. There are epidermal hairs in the upper half of the hypocotyls. The cotyledonary petiole has dense hairs, too. Under natural conditions at Shizuoka-city, flower buds were finally recognized in late October. The corolla is light blue, but its throat and midpetaline bands have a bit of a reddish tinge. The flower diameter is 6 cm. The flower tube is white. Light-brown epidermal hairs extend to the calyx. One flower is generally observed per peduncle, but there can frequently be up to four. This strain closely resembles Colombian Y023 in many characteristics.
