This is a large unifoliate species with a linear leaf. It was grown by Chris Rose from seed provided by Isobyl la Croix in Scotland, a former distributor of species Streptocarpus. She probably received the original material from Martin Kunhardt in South Africa, or collected it herself. The plant bloomed in 18 months from seed. A closeup of the flowers may be seen here.
Chris Rose reports that this clone is strongly scented, with the scent detectable from 3 meters in an enclosed room. He thinks it smells like over-ripe bananas, while others are reminded of curry.
