The plant we now introduce to the notice of our readers is very distinct from the ordinary types of Orchids, and is remarkable for its reed-like stems, and its very charming and beautiful blossoms. Its habit is to keep flowering in succession for a long period. When better known it will be much sought after; at present there are but few plants in cultivation, at least very few have come under our notice. There exist several varieties which vary in the colouring of their flowers; that which we now figure being a very good type. We are indebted to T. D. Cunningham Graham, Esq., Dunlop House, Stewarton, Ayrshire, for his kindness in sending the specimens for the use of our artist. A description of the Orchids at Dunlop House will be found under plate 118 of our present volume. _Arundina bambusæfolia_ is an evergreen plant, with reed-like or bamboo-like stems, bearing foliage of a light green colour; the sepals and petals are pale magenta-rose, the lip rich rose shaded with magenta. It grows, in its natural state, from three to five feet in height, and produces its flowers from the top of the stems about July, continuing to bloom for some time during the summer and autumn months. Mr. Kemp, the gardener at Dunlop House, thinks it a most useful plant. We find this Orchid to do best when grown in a pot, with good drainage. The material most suited to it is good rough fibrous peat and loam mixed together. It is a free-rooting species, but has no thick fleshy bulbs from which to draw support. These Orchids which have these reed-like stems require to be potted in a richer soil than others; they grow after the manner of the _Sobralia_, and require similar treatment, that is, the treatment of the cool end of the East India house, with a good supply of water during the growing season, and to have the soil kept moderately moist when at rest; the plants need plenty of light, but should be shaded from the rays of the burning sun. They must be kept free from insects, or the thrips will soon injure their foliage. They are propagated by dividing the crowns, and they also produce plants on the stems, which can be taken off and potted when they have formed roots. We saw some fine plants of this Orchid in the collection of W. Lee, Esq., of Leatherhead, which were producing shoots in this way quite freely, and these being taken off, soon formed young established plants.
