On the Species of the Genus Primula in Essex. 193 calyx-tube. In 1881 the calyxes of several flowers on a plant that usually produces normal flowers continued to develop into leaves about 11/2 in. long, after the corolla had withered some weeks. My friend Mr. P. Sewell, of York, has sent me specimens of flowers having the corolla foliated exactly as the calyx so often is. The plant bearing these was originally found wild in Ireland. I believe this is a rare aberration. It is not my intention here to speak of the numerous forms which this species assumes under cultivation; but I may describe the strange conduct of one plant that grew in my garden at Chignal, and produced all through the autumn of 1879 flowers which were normal in all respects, except that they were red and had a calyx of five small leaves each about one inch long. By the middle of the following May the blooms were few in number, and changed in nature, the calyx-leaves being then smaller and shorter. The central part of each was still green like a leaf, but down each side was a wing or strip half as broad as the green part, which was smooth and coloured like the petals, so that the flowers were evidently inclining towards the "Hose-in-Hose" variety. The following autumn, if my memory serves me, the flowers bore ordinary leafy calyxes. Polyanthuses with a parti- coloured calyx may sometimes be seen in gardens, but I do not know that they ever change their nature. As is also the case with the Cowslip and Oxlip, the corolla withers up, but remains on the plant for a long time. The capsules differ in their shape and habit from those of the other species, being much shorter and rounder, and prostrate instead of erect. They lie down upon the ground when mature, and it is possible that this may be the means adopted by the plant for sowing its own seed, as I have sometimes seen the capsules quite covered up by worm-casts. The dead capsules do not, I believe, remain on the plant until the follow- ing year, as is the case with most other species of Primula. All gardeners know how persistent sparrows are in pulling off the Primrose-petals for some reason best known to them- selves. Sparrows, however, are not the only delinquents, as
