Some excellent examples of this fine plant were shown at the meeting of the Royal Horticultural Society on the 7th of September. They were in large pots, and had been in them for five years, and were finely bloomed, several trusses of bloom being on each plant. They were exhibited by Mr Pilcher, gardener to S. Rucker, Esq., Wandsworth, S.W., and the treatment to which they had been subjected was simple in the extreme. They are grown in a warm greenhouse all the winter, where the temperature does not fall below 40 degrees. In summer they have just enough water to keep them alive, and then they form their flowers. Just now they are making their growth. The soil at the growing season should be kept damp. The variety known as Eximea is an improved form, having broader petals and a rather brighter hue of colour.
