by the fact that the plant in the New York Botanical Garden from which the illustration was prepared was secured in 1895 from the Arnold Arboretum Viburnum dilatatum was introduced into England about 1875 by the Messrs Veitch, and has since then become widely spread in cultivation qualities, as is indicated A general discussion of the genus Viburnum, including methods of propagation, will be found in volume of this periodical, at the information there presented it may be added that in the northeastern parts of North America there are fourteen page 55 To and three others United States, making a total of seventeen species for eastern North America But it is in eastern Asia that the genus finds its greatest representation, about sixty-five species being known from that region Thunberg's viburnum in habit is an upright shrub up to ten feet tall, bearing its white flowers and scarlet fruit in broad flat-topped clusters The branches of the year are clothed with a rather long dense pubescence, the older branches finally becoming glabrous The leaves are opposite, each on a densely pubescent stalk commonly less than a half inch long The outline of the blades is oval, broadly ovate or obovate, or orbicular or nearly so, the apex being abruptly pointed and the base rounded; they are densely pubescent on both surfaces, especially the lower, in age the pubescence becoming sparser; they measure commonly up to three species native, in the southeastern inches long, occasionally more, and have the margin, except at the very base, coarsely toothed, the ultimate veins excurrent as short points on the teeth The flowers are in broad flat cymes up to six inches across, the stalk and branches densely hirsute The corollas are about a quarter of an inch broad, pubescent externally, and are on short hirsute pedicels The fruit is scarlet George Explanation op Plats Fig 1.—Flowering branch V Nash Fig 2.—Fruiting DIPLOTAXIS TENUIFOLIA Mustard Family Family Brassicaceae Sisymbrium tenuifolium L Cent tenuifolia DC PI 1: 18 Syst 2: 63 1755 1821 In 1916, plants of a mustard-like character were grown at the New York Botanical Garden from seed received from the Zurich botanical garden, and they proved to be Diplotaxis tenuifolia The pale green foliage and light yellow flowers made a rather pleasing combination of color, and the fragrance of the blooms was not unpleasant The branching and floriferous habit suggested possible value as a flower garden subject, and the following year plants were raised from collected seed and placed in the flower borders near Conservatory Range From these plants our illustration was taken The wall-rocket has inclined to spread over more than its allotted share of ground, and to become weedy in habit, but it has a long blooming season, and a plentiful supply of small flowers, giving, with the gray-green leaves, the same general color effect as the yellow alyssum, Alyssum saxatile compactum It must be kept within bounds, especially by discarding seedlings which spring up within several yards of the old plants The plant may readily be propagated by seeds found so often on old walls in England, with other related species, is the Sisymbrium tenuifolium of older botanies, described by Linnaeus in 1755, but later separated into the genus Diplotaxis, of which tenuifolia is the type species It differs from Sisymbrium in having a flattened pod, and in the arrangement of the cotyledons in the seed; and from Brassica in having the seeds in two rows in each half of the pod In this country it is adventive from Europe, occurring near The wall-rocket, so called because it is the sea-coast in the northeastern States and California The wall-rocket is an annual or biennial herb, one to two feet high, bushy and branching, with smooth somewhat glaucous stems The leaves are slightly glaucous, gray-green in color, pinnatifid, the lobes sinuately toothed, the lower ones three to four inches long, alternate, and sessile, the upper smaller and more % Addisonia nearly entire The flowers are half an inch or more in diameter, in terminal, many-flowered racemes: there are four deciduous green lanceolate sepals, four clawed yellow petals with spreading limbs, six stamens, and a pistil with slender style and persistent stigma In fruiting the racemes lengthen, bearing on long slender pedicels the pods (siliques) with the styles persistent as slender, short beaks The two-valved siliques are flat, one-nerved on each side, and about one inch long, with many seeds in two rows in each valve KSNNSTH R BOYNTON Explanation of Plate Fig 1—Portion of stem and leaves Fig 2.— &Bk M 'IERIS FLORIBUNDA KOELREUTERIA PANICULATA Native of Japan, Corea, and China Family Sapindaceae Koelreuteria paniculata Soapberry Family Laxm Novi Comm Acad Petrop 16: 561 1772 Sapindus chinensis Murray, Syst Veg 315 1774 Koelreuteria chinensis Hoffmgg Verz Pfl 70 1824 Here a tree for our July or August, when make it is most few trees summer months, for its large clusters of it comes into bloom in bright yellow flowers attractive, especially so at that time as there are then bladdery fruit follows in September, again making of the tree an interesting object It has a round head in flower Its curious and large compound leaves which make it distinctive in the land- scape during the summer season It is not particular as to soil, and prefers a sunny situation; as it stands drought well and survives under hot winds, it is much grown in the central west, from Kansas and Missouri southward, where it is known as "Pride of India" or " China tree." This tree is hardy in the latitude of New York city, and as far north as Massachusetts, although there it sometimes kills back in severe winters It has been in cultivation at the New York Botanical Garden for many Specimens of it will be found in the deciduous arboretum, and another specimen along the road near the viburnum triangle south of the Museum; it was from the latter, which has been in the collections since 1906, that the illustration was prepared Propagation is effected by seeds, which may be sown in autumn or years by root cuttings There are five known species of the genus Koelretueria, that here considered being the only one commonly cultivated Of the restratified; also maining species three are from China and one from Formosa The varnish tree in cultivation seldom attains a height of over twenty-five feet; it has a rounded rather dense head The leaves are alternate, unequally pinnate, or rarely bipinnate, petiolate The leaflets are seven to fifteen, shortly stalked; the blades are ovate, elliptic, or oblong-ovate, with the apex obtuse or acute and the base rounded and abruptly wedge-shaped, and the margin coarsely crenate-serrate, or lobed, especially at the base, the teeth or lobes serrate; they measure up to four inches long and over hall as wide, and have the surfaces glabrous, except the pubescent Addisonia 62 The inflorescence nerves, the lower surface paler than the upper is terminal, ample, up to eighteen inches long, the axis, branches, and pedicels minutely pubescent The irregular polygamous flowers are about a half inch in diameter; the sepals are unequal, obtuse or acute, about a twelfth of an inch long, ciliate; the four upturned petals are linear-lanceolate, obtuse or acutish, spreading, somewhat undulate, yellow, clawed, the claw with two small appendages which are at first yellow, later red; the disk is erect, The declined stamens are eight, or sometimes fewer, with lobed long hairy free filaments The ovary is oblong, three-angled, pubescent, with a long style; ovules in each cell two The fruit is a bladdery three-lobed capsule up to an inch and a half long The seeds are black, globose, up to a quarter of an inch in diameter George V Nash EPIPHYLLUM HOOKE EPIPHYLLUM HOOKERI Hooker's Epiphyllum Native of Trinidad Family Cactaceae Cereus Hookeri Link & Otto, Cactus Family Cat Sem Hort Berol 1828 Epiphyllum Hookeri Haworth, Phil Mag 6: 108 1829 Phyllocactus Hookeri Salm-Dyck, Cact Hort Dyck 38 1842 In tropical America there is found a very interesting genus of Unlike the cacti from the desert cacti known as Epiphyllum regions of Arizona and Mexico with which we are most familiar, the plants of this genus not grow in dry regions but are often found in dense rain-forests; like their desert allies they too must have xerophytic conditions, so they grow on the bark of trees and are known as epiphytes These plants not have leaves but the stems are flat, green and leaflike, functioning as leaves The flattened stems were at one time supposed to be leaves upon which the flowers were borne, which is the origin of the name Epiphyllum The genus contains about twenty-fc central Mexico through Central America to central South i None are known to be native in the West Indies, except in Trinidad One or more, however, have been described from Cuba, but these were doubtless based on cultivated plants It is possible that there are species in the mountains of Santo Domingo or in the southern Antilles which will be found when those regions are more thoroughly explored A number of epiphyllums are in cultivation and some of them are highly prized as ornamentals Some are night-bloomers while others are day-bloomers; some have large sweet-scented Epiphyllum oxypetalum, generally known as Phyllocactus flowers bifrons in the trade, is a great favorite The name Epiphyllum dates back to 1689 when it was first used by P Hermann Its use, however, as a generic name in the modern sense dates from 1812 when it was used by Adrian H Haworth, who made it a new genus based upon Cactus phyllanthus Some years later other plants were referred to Epiphyllum, and still later the type of the genus Epiphyllum was made the type of a new genus, Phyllocactus, and the name Epiphyllum was used for a totally different plant, Epiphyllum has original type, while the "Epiphyllum" namely Epiphyllum truncatum recently been restored to its 64 of the gardens shown in our illustration is cultivation in gardens The which is native to Trinidad and has long been in becomes Zygocactus truncatus species and conservatories Hooker's epiphyllum has stems at first erect, but soon drooping, often becoming pendent, and six to ten feet long; the branches are very variable, either long, slender and whip-like, or broad, thin and The lateral branches are sometimes three inches broad, with a crenate margin The flowers appear at night, and are sweet-scented; the flower- tube is very slender; the outer perianthsegments are lemon-yellow while the inner ones are pure white; the filaments are white The fruit is oblong, about two inches long, I and red - J Explanation of Plate Fig 1.—Flower Fig 2.—Upper N Rose part of stem INDEX Bold-face type is used for the Latin names , < including synonyms Physalts Franchetii, 57;
