Garden and Forest. across and remarkable in having the three dorsal segments erect and the two lower ones horizontal, their color being!bright yellow, with lines of green. The lip is small, delicately hinged and purplish in color. Odontoglossum ex-.cellens chrysomelanum, also from Sir Trevor Lawrence, was awarded a first-class certificate. It is remarkable for the clear yellow and the almost crimson color of the blotches of its segments. Dendrobium Sybil, a hybrid between D. Linawianum and D. bigibbum, raised by Mr.,Cookson, was deservedly awarded a first-class certificate, -its purplish-yellow-throated large flowers being both distinct and attractive. The following plants were among the miscellaneous ex-.hibits:Andromeda Japonica, a group of bushes six inches -high, clothed from top to bottom with large panicles of Lily-of-the-valley-like flowers-perfect cascades of white bells. Bignonia venusta, shown from Lyon House, where,this grand greenhouse climber has been a feature for many years. Its long string-like shoots are clothed to a length of several yards with bunches of large tubular orange-yellow flowers. It is one of the finest of the genus. Rhododendron albicans, a hybrid between R. mollis and R. occi-.dentalis, raised about ten years ago by Mr. A. Waterer, was Shown in flower, and obtained an award of merit. It Jis exactly like R. mollis in foliage and size of flowers, which are pure white, with a blotch of lemon on the upper segments, and are produced in large full trusses. -FERRARIA ANTHEROSA is a singular-looking Irid from the Cape, with stems two feet high, clothed with fleshy amplexicaule leaves and greenish purple, Iris-like flowers. It <is grown at Kew, and is interesting to those who are botanically inclined. RHODODENDRON RACEMOSUM, from Messrs. J. Veitch & Sons, is a delightful little pot-shrub, which is said to be hardy at,Coombe. It is less than a foot in height, and has Box-like -foliage and numerous compact little trusses, two inches in diameter, of white flowers with pink tips. It is a distinct and promising little plant, for the introduction of which we -are indebted to the French horticulturists, who obtained it from Yun-nan. LOROPETALUM SINENSE is a rare little shrub, related to Hamamelis, with alternate ovate leaves an inch long and clusters of flowers with long, narrow, whitish petals. It might be made a useful plant for the cold greenhouse. It is a native of China, and is not hardy here. Messrs. Veitch:showed a basket of nice little specimens of it covered with flowers. SHORTIA GALACIFOLIA was shown in finer condition than -I had ever before seen it, plants in small three-inch pots, and no larger than a man's fist, carrying about twenty pure;white, nodding, fringed bells. It is a charming little alpine,'hardy with us, and I learn it is likely soon to be abundantly represented here, one garden alone possessing a large -frameful of healthy, newly imported plants. STREPTOCARPUS WENDLANDII. —A group of this distinct new species was shown by Messrs. Sutton & Sons. It is remark-:able for the size of its single leaf, which rivals that of S. Dunnii in size, but differs in being less wrinkled and in,being purple beneath. The flowers are borne on erect.stout scapes two feet high, freely branched and clothed with a perfect sheaf of violet-purple white-eyed flowers one and a half inches across. The introduction of this plant is mysterious. About eight years ago a chance seedling came up in the fernery at Kew. It was soon seen to be distinct, and in two years its single leaf was three feet long by two feet in width. When it flowered it was thought to be a variety of S. Saundersii, of which there is a figure in the Bo/anical Magazine, t. 5 2 5 I. About three years ago it was offered by a Continental nurseryman under its present name. There are some fine plants now in flower at Kew which are hybrids between it and S. Dunnii. The flowers are large, not unlike those of S. Wendlandii in shape, but colored deep magenta. VRIESIA REX, a hybrid or seedling shown by Monsieur Duval, of Versailles, received an award of merit on account of the deep, uniform crimson color of its large imbricating bracts, which contrast prettily with the yellow flowers. It belongs to the same set as V. psittacina and V. Morrineana. BLUE PRIMROSES were shown by Mr. G. F. Wilson, a collection of some three dozen flowers of various shades of blue, plum-blue, lavender, etc. There are true blues among them. London. W. Watson. New or Little-known PlanIs. Prunus Watsoni. FOR a shrubby Plum which has been growing in the Arnold Arboretum since i88o, when it was raised from seed sent from Ellis, Kansas, I propose the name of Prunus Watsoni * (see page I35), in honor of Dr. Louis Watson, of Ellis, a brother of the late Sereno Watson, through whom I first became acquainted with this plant. As it grows in the Arboretum, Prunus Watsoni is a twiggy shrub three or four feet high, with slender; rigid, zigzag branches which are bright red and lustrous during their first year, and later growing darker, are marked with pale lenticels, and develop spur-like lateral branchlets. Thd winter buds are acute, an eighth of an inch long, and are covered with many closely imbricated, light chestnutbrown scales; those of the inner ranks are accrescent, and at maturity are half an inch long, three-lobed, with small acute lateral lobes, and a larger terminal lobe, rounded at the apex, and remotely crenulate-serrate. The leaves are an inch to an inch and a half long, half an inch to twothirds of an inch wide, thick and firm, lustrous on the upper and pale on the lower surface, with slender midribs, obscure veins, and bright red petioles half an inch in length. The flowers, which appear about the middle of May, are very fragrant, and are produced in the greatest profusion, quite covering the branches; they are borne on slender glabrous pedicels a quarter of an inch long, in crowded three to four flowered fascicles, and when expanded are half an inch in diameter. The fruit, which ripens in great quantities, and sometimes hangs on the branches late into the winter, is two-thirds of an inch in diameter, with a thick bright orangered skin without bloom, and bright yellow juicy flesh, which, although slightly austere, is edible, and sometimes of good quality. It is this plant which is the Sand Plum of southern and south-eastern Nebraska and central Kansas, where it forms thickets in low sandy soil near streams. On the banks of the Saline River, where, ten or twelve miles from Ellis, it is very abundant, the plants vary from three to ten or twelve'feet in height; on some individuals the fruit ripens early in August, and on others as late as the Ist of October. The Sand Plum is occasionally planted in the gardens of central Kansas, and the wild fruit is gathered in large quantities and sold in the towns. Prunus Watsoni has been mistaken by travelers in the trans-Missouri region for Prunus angustifolia, the Cherokee Plum, from which it differs in habit, in its thicker leaves, thicker-skinned fruit and smaller stone, the stone of Prunus angustifolia being less deeply pitted, thick-margined on the ventral suture, conspicuously grooved on the dorsal suture, and less abruptly flattened at the apex. The hardiness of Prunus Watsoni in regions of extreme cold, its compact dwarf habit, abundant flowers and handsome fruit make it an ornamental plant of first-rate value, and as selection and good cultivation will doubtless improve the size and quality of the fruit, it will, perhaps, become a valuable inmate of small fruit-gardens. C. S. S. * PRUNUS WATSONI, n. sp.-A shrub six to ten feet high. Leaves, ovate, acute, rounded or wedge-shaped at the base, finely crenulate-serrate, lustrous on the upper, pale on the lower surface; petioles slender, grooved, bi-glandular at the apex. Flowers in crowded few-flowered fascicles; calyx cup-shaped, the lobes acute, rounded at the apex, eglandular, ciliate on the margins, pubescent on the inner face; petals inserted remotely on the glandular disk, narrowly obovate, rounded and more or less erose above, contracted below into short claws, pure white; filaments glabrous; anthers minute, obtuse, yellow or bright red; style slender, exserted. Fruit globose, or rarely oblong, oranze-red; putamen turbid, rounded on the ventral suture and rounded and sometimes obscurely grooved on the dorsal suture, abruptly compressed at the narrowed apex, thick-walled, conspicuously porulose.
