This Chinese production is worthy a place in every greenhouse, its singular and pecu liar shaped flower being quite distinct from anything out at the same time - a point of considerable importance in a selection of plants. Its habit, too, is drooping and graceful, its delicate rose-colored and purple-tipped blossoms hanging like ear-drops from several axillary racemes. It is probably nearly or quite hardy enough to stand our winters, of which I am unable to speak from experience; but, with a slight protection of its roots it will undoubtedly stand, and form a magnificent object in summer. Its culture in the greenhouse is simple, requiring no important room a great portion of the time; and, by having a succession of plants, may be had in flower from the first of February till those in the open air come in. It is very impatient of much heat, and, if fine specimens are wanted, should at no time receive a temperature over 50° artificial heat; solar heat it does not mind.

We procured a huge root from the open ground of a nursery, on the 4th of November, and gave it the following treatment It was potted at once in a 18-inch pot. The root had to be divided into three parts to get it in, using loam and rotten dung - two parts of the former. one of the latter - with a little sand to fill up the remainder of the pot. It was then set in the coldest part of the house, on the floor, and but seldom watered till it began to push, which was about the middle of January It was then more freely watered, and as soon as the growth had lengthened to six inches, lifted to the front stage. It now began to grow rapidly, and was occasionally treated with a dose of weak liquid manure water. On the 23d we had it at our show, and on March 7th made the following entry in our note-book: "Dielytra spectabilis - thirteen spikes eighteen inches high, from four to six racemes on a spike, from eight to twelve blossoms on a raceme." It is still beautiful, and likely to be for some time yet, as several of the spikes that remained dormant at first have since started, and laterals spring from those that first flowered, which keep up a succession.

As soon as it has exhausted itself it will be cut into pieces, to form cuttings. These will be struck and turned into the flower-garden for summer display, from the roots of which a large stock will be laid in for next winter's operations.

[The Dielytra stands our climate at Rochester without protection. It is, without exception, in our opinion, the finest hardy herbaceous plant introduced within the last twenty years. Our experience with it in the house enables us to endorse all that Mr. Sanders has said of it. Our artist has taken a drawing of this beautiful flower, which we shall probably give in the July number. - Ed].
