Begonia Piitzeysiana is a very free-growing plant, if kept in a 
warm greenhouse, and potted in a mixture of sandy loam and a 
little peat. It flowers freely, should have plenty of pot-room, 
and is easily increased by cuttings and seeds. I have had the 
plant for many years under cultivation, but from what source 
I obtained my stock I have no clue. — W. W. S.
