Many garden folk are very fond of cultivating plants of this class, as many of them are very grand, stately, and graceful in their habit of growth; others are remarkable for the great beauty and delicacy of their inflorescence; and all are of easy cultivation, thriving in any ordinary well-manured soil.

For the information of such of our readers as may not yet have attempted their cultivation, we append notices of some of the most desirable sorts. Apart from their use as garden decorations, their flower heads make, when • properly dried, very beautiful mantel ornaments, unequaled by any other class of plants for the elegance and airiness of their forms. We particularly recommend them to those whose higher artistic cultivation has taught them to appreciate the beautiful in form rather than in color.

The Gynerium argenteum,or Pampas Grass, of South America, is the largest grass grown. It forms large tufts of leaves about three feet long, which recurve very gracefully, and are of a glaucous green color; the flower stems are from five to ten feet high, furnished with leaves for a portion of their length, and terminated by silvery, silky, branching panicles of flowers, the panicles being from twelve to twenty inches in length. The plant is dioeci-0UB - that is, some plants produce male flowers and others female flowers; the first are much less beautiful than the latter. There are some eight or nine varieties now grown in Europe, three of which have variegated leaves, one has light rose - colored, and another has pale violet-colored plumes; but these have not been introduced into this country that we are aware of. The plant is not quite hardy in this latitude, and should be grown in a large tub (a half-barrel, for instance), or, if planted out, should be taken up in the autumn and kept in a warm cellar; at the south it is quite hardy.

Erianthus ravennce, or Ravenna Grass, is a native of Italy. It is similar in appearance to the Pampas Grass, differing, however, in the form of the plumes. It has long, graceful foliage, throwing up flower stems six or seven feet high, terminated by graceful, drooping, feathery-like plumes from fifteen to eighteen inches long; these have a silky appearance, and are of a silvery white color. The plant is hardy in this latitude, but northward would require to be protected with leaves.

Agrostis nebulosa is a very beautiful annual grass, with stems from twelve to fifteen inches high, with from five to ten whorls of long hair-like branches terminated by the flowers, the whole forming a graceful, airy, feathery panicle. These panicles, cut before the seeds are ripe and dried in the shade, can be preserved for a long time, and either in their natural state or dyed are used by milliners and artificial flower makers.

Briza maxima, or Quaking Grass, an annual with flower stems from twelve to twenty-four inches high, with large calycine scales, which form close, flat, rather long, heart-shaped pendent objects, with delicate, flexible footstalks, that allow them to move with the slightest movement of the wind. Another species, B. gracilis, is similar to the above, only differing in being dwarfer and more delicate in habit.

Air a pulchella, in some of the seedmen's catalogues inserted as Agrostis pulchella. This very elegant and graceful grass is an annual, growing from eight to ten inches high, producing numerous thread-like flower stems, terminated by erect, delicate, graceful panicles. These being cut, and dried in the shade, can be kept for a long time, and, like the Agrostis, are used by milliners and artificial flower makers.

Lagurus ovatus, or Hare's-tail Grass, is pretty dwarf-growing species, whose flower stems are terminated by upright, soft and velvety heads of flowers, which, being cut before their complete maturity, are readily preserved for winter bouquets, and are also used for the coiffures of ladies.

Panicum capillaceum is the Eragrostis ele-gaiis, or Love Grass, of some of the seedsmen. It is an annual, although it is stated in some catalogues to be a perennial. It grows from eighteen to twenty inches high, and has large panicles of flowers lightly tinted with rose color on the exterior. It is not as strikingly ornamental as some of the others, but is useful for winter bouquets.

Pennisetum longistylum is generally grown as an annual, but at the South would be a perennial. It is a very elegant species, growing from eighteen to thirty inches high, the flower stems producing long, white, gracefully curved plumes, which are very desirable for winter bouquets. This species requires a light, rich soil, and if the season is dry, should be well watered.

Stipa pennata, or Feather Grass, is one of the most beautiful of all grasses. It is a perennial, growing from eighteen to twenty inches high. The plumes are long, remarkably light, and flexible, and have a strong resemblance to marabout feathers, and are used by the milliners and artificial flower makers as imitations of them.

Ulalia japonica is a perennial hardy species from Japan, with long; variegated leaves. The flower stems are from three to four feet high, very reed-like, and produce loose panicles of flowers; these panicles are hairy and erect until dried, when they become elegantly curled, closely resembling Ich dien feathers. It is a remarkably elegant species.

Hordeum jubatum, or Squirrel-tail Grass, is an annual, growing from twenty to thirty inches high, the plumes being from four to six inches long, sometimes straight and sometimes gracefully curved; the scales of the flowers are terminated by long awns, which are green at the base and of a light rose color at the summit; these awns have the appearance of bristly hairs.

Festuca glauca is a dwarf-growing species, with upright, very glaucous green leaves. This plant is admirably adapted for edgings, growing very densely, and not inclined to run or spread. It is of recent introduction to our gardens, and we believe that it will in many cases supersede box edgings. It is perfectly hardy, and is a perennial.

Besides the above-named species, there are others of comparatively recent introduction to be found in the catalogues, some of which may be worth growing; the above selection, however, includes the most striking or picturesque species. Closely allied to the grasses are some species of Bamboo, which stand our winters here with but slight protection, as Bambusa metake and B. fortunii variegata. Arundo donax variegata is a hardy, reedlike plant, with the stems growing four to five feet high. The latifolia is also a reed-like plant, from five to ten feet high, with long, recurving leaves; is not hardy at the North, and must, therefore, be kept in a warm cellar in the cold season. - Harper's Bazaar.
