It is a matter of astonishment that the beautiful Australian plants, generally winter-flowering, are not more generally grown in our greenhouses. Some of them with delicate hair-like roots, suffer from our dry summer heats, but those with heavier ones do well. At a recent Germantown Horticultural Society meeting, Mr. Lonsdale exhibited a plant of Grevillea robusta, which, besides the beautiful and curious flowers it will have, as it grows older,has pretty fern-like foliage. It ought make a good room plant as well as a •desirable one for the greenhouse.
