This member of the Gesneriaceae
family comes from East Brazil. It was given this name by Hans
1978. It doesn't need much water, but a lots
of sun. The flowers are red. The caudex will grow to eight centimetres the
stem to 40 centimetres.
I got the seeds from Tsuh Yang in New York. He found them in Rio
de Janeiro, RJ State, Brazil
2001. He writes: "...as for bulbosa's tuber, it is light coloured
(sort of like ginger root) and it grows on rocks in beaches of Rio de
Janeiro. Some of those I saw, were at least 5 kgs, very big".
