The description was made from the type collected and about 100 plants which were grown from the seeds obtained from this self-pollinated plant. This is another lovely and entirely different begonia from those we have been growing. We are indeed indebted to Mr. MacDougall for this lovely, hairy, rhizomatous begonia which makes a beautiful house specimen with its lovely, hairy, green leaves and light red flowers. Since it blooms in the fall and winter, it should be repotted in the summer when new leaves are seen to develop. A fern pot (a shallow pot) should be used to accommodate the creeping stem for they do not like to be too wet at the roots. Care should be taken to see that the tip of· the rhizome is well back from the edge of the pot so that ample growth may develop before the edge is reached.
