The extent to which the culture of orchids has reached, since the Gardener's Monthly and other magazines have done so much to simplify the mystery with which the older times loved to surround their treatment, is very remarkable. Almost every one who has a greenhouse now has a few orchids, and they are almost always present in some collections at horticultural exhibitions. At the March meeting of the Germantown Horticultural Society, Mr. Wm, Jamison, gardener to Geo. L. Harrison, Esq., had a fine plant of the rare and beautiful Phalamopsis grandiflora, one of the moth orchids. Cypripedium villosum was shown by Alexander Young, gardener to Mr. R. S. Mason, and the old but very beautiful Bletia Tankervillae or Phajus grandiflorus, as its name is considered more properly to be. This last seems to have bloomed more freely everywhere this year than last, and leads one to suspect that even in the hands of good gardeners, greenhouse flowers have their seasons. The Phajus is popular as a cut-flower, as indeed most orchids are.
