Soc. 18: 236. 1880, A plant with a stout rootstock and a short caudex on which many leaves are crowded. ‘The leaves are greatly elongate, bright-green and shining, and in the wild state lie procumbent on the ground, thus form eta a mat about the plant; their dilated bases are two inches long or less and closely imbricate, the outer ones thick, yellowists ‘and abruptly dasedwea into the blade, while the inner are often a yard long and taper from about one fifth of an inch wide at the base to a very slender tip; they are striate on both sides, half-round below and triquetrous toward the apex; the edges are usually decidedly roughened. ‘The flowering stem arises from the caudex and is surrounded at the base by the cluster of Bape During the flowering period it is much shoetee than the leaves and even in fruit when it lengthens it rarely exceeds them. ves pe- duncle is very short and the internodes of the flowering stem are only about an inch “bas: The bracts subtending the iors “ lateral panicles of the inflorescence have broad een -mar anthers are shorter than the Ferien The ovary is ovoid, white or greenish-white, and is tipped with three short-subulate styles. The capsule is depressed, and usually about one sixth of an inch long. This plant was first collected on the Cibolo River, a tributary of the San Antonio River, in May, 1846, by Ferdinand Lindheimer. For a period of over thirty years it was referred to species to which it was not closely related, and not until 1879 did it find a place in 2 ADDISONIA the genus to which it really belonged. Notwithstanding the apparent abundance of the plant in its natural range, it has been collected but relatively few times. The specimen from which the accompanying plate was made was collected by D. T. MacDougal near Austin, Texas, in 1902. The plant flowered in the conservatories of the New York Botanical Garden in February, 1905. This plant is known, locally, as “ bunch-grass,’ ’ and also as ““bear-grass.” The latter name, however, is mostly associated with a related plant of the same region, a species of Dasylirion. Joun K.

Trichosterigma benedictum Millsp A low shrub a foot or more high, with abundant milky juice. The main stem rises from a deep, fusiform root, and is short and stout, an inch or two thick, separating into a few knotted, pongo os branches; the whole covered with a close, smooth, shining bark. ‘The leaves, mostly clustered on the short branchlets, are a inch or two long including their petioles; the blades are broadly obcordate or at times but slightly notched at the broad apex, up to about an inch wide, entire, light green and ee oe eae really slightly puberulent under a lens. The “ flowers” are produced singly or in groups of two or three from re eile of “the terminal leaves; they are borne on Bee Soe up to an inch long; the flower-like involucres are composed of atise and showy, cream- white, petal-like lobes which ane ae slightly notched at the apex and bear each a more or less kidney-shaped, greenish yellow gland at the base. The true flowers are represented by a number of stamens, with short filaments, surrounded by fascicles of strap- shaped bractlets and a single central pistil which soon protrudes far beyond the involucral cup and bends gracefully downward with the ripening of the fruit; the three styles are connected at the base, each divided into two branches above the middle and each branch bearing a strongly recurved stigma. e fruit is smooth, pro- portionally large, 3-carpelled, the carpels coor, and strongly keeled. The seeds are ovoid-globose, blue-gray, deeply and rregularly angularly pitted (almost Laeeycombed) and have a broad, distinct, deep brown ventral line This interesting shrub, very attractive in cultivation, grows only upon the islands of the Saint Benedict group, four miles in extent, lying some twenty miles seaward from the northern end of Cedros Island off the coast of Lower California. The plant was first brought to notice by Lieutenant Charles T. Pond of the U. S. 5S. Ranger, in 1889. The shrub abounds in milky juice which flows instantly from the slightest wound of any part of the plant The stems are very spongy and soft, scarcely woody; the root is soft and farinaceous with a tender, palatable interior devoid of the milky 4 ADDISONIA juice. Plants may be readily grown, under proper temperature conditions, from cuttings; these, as the juice seals the wounds and prevents drying out, will remain alive for a considerable period. The genus Trichosterigma of Klotzsch & Garcke (Abh. Akad, Wiss. Berlin 1859': 41; misquoted by Boissier as Tricherostigma in DC. Prodr. 15?: 68) is based upon Karwinsky’s Euphorbia fulgens as its type. It is characterized as follows: hrubs. Stems not articulate; leaves alternate or Boe eies entire, exstipulate. Inflorescence axillary, solitary o mose; involucres broadly campanulate, limb large, 5- tobed. aentnte. patent, contorted in the bud. Bracteoles of the male flowers linear-subulate, ciliate above, naked below; styles connate below; seeds ovoid-globose, runes pitted, ecarunculate, marked with a dark, broad ventral lin ‘The species are all es the xerophytic regions of Southern Cali- fornia, Mexico, and Central America; they are, in addition to the above, Trichosterigma fulgens, T. californicum, T. Hindsianum, and T. miserum. C,. F. MILLspaucH.

The leaves, which are opposite and on very short stalks, are oval to elliptic-ovate, wedge-shaped or rounded at the base, sharp-pointed at the apex, two to four inches ong and one and a half to two inches wide. ‘They are appressed- pubescent on both surfaces, especially the lower, dark green above and paler beneath; the nerves are curved, their upper axils on the lower surface usually with brown hairs. The flowers, which appear after the leaves, are in heads, one quarter to three eighths of an inch in diameter, subtended by usually four spreading, ovate, sharp-pointed, cream-white bracts up to one and a half inches long e quarte Of all the trees which adorn our woodlands in the spring, none exceeds in beauty and attractiveness the flowering dogwood, Cynoxylon floridum. Its mantle of white makes of it a striking feature, when many other trees are in their uniform of green. ‘The flowering dogwood of Japan is equally striking, though perhaps not of so great stature, and must be one of the most admired of all the trees and shrubs of the wooded mountains of Japan, where it grows usually at elevations between 2000 and 4000 feet. Unlike our flowering dogwood, its blossoms appear after the leaves, the contrast of the white starry blossoms with the dark green of the foliage at once arresting the attention. In the fruticetum collection 6 ADDISONIA of the New York Botanical Garden there are a number of the Japanese flowering dogwoods. It was from one of these, obtained in 1904, that the illustration here presented was prepared. There are two woody genera of the dogwood family with invo- lucres of large showy bracts, Benthamia, three species, of Asiatic distribution, and Cynoxylon, two species, of the United States. Benthamia is nearly related to Cynoxylon, but differs in the ap- pearance of the flowers after the leaves and in the fleshy fruit, made up of many united berries; in Cynoxylon the berries are separate. Of the three species of Benthamia, one, Benthamia capi- tata, is found in the Himalayan region, another is known only from Hongkong, and the third is the one here illustrated. Of these only the last is hardy in this latitude and as far north as Massachusetts. It should be more generally cultivated than it now is. In the col- lections of the New York Botanical Garden it has flowered annually, the first time in June, 1913. GEORGE V. NASH. EXPLANATION OF Pate. Fig. 1—Flowering branch.

A perennial herb, finely puberulent throughout, with a simple leafy stem a foot or more in height, growing from a globoid or oval slightly annulate tuber, and bearing its flowers two to seven together in simple short- peduncled axillary cymes which in well- -developed plants form together a loose interrupted thyrse. The stem is mostly stout but weak, its internodes less than half the length of the leaves, which are opposite, those of each pair being eters’ and short-petioled; the blades are two to five inches long and a half to two thirds as broad, ovate, acutish, cordate, irregularly APD with both teeth and sinuses either acutish or obtusish, the margins densely and shortly ciliate with white hairs, thin, green and grayish- hairy on aces, veiny, the veins slender, reddish the sec- ondaries alternate or subopposite, the branches somewhat anasto- mosing. The peduncles are subtended by reduced sessile or clasp- ing leaves, the upper by mere bracts. The pedicels are mostly longer than the peduncles, but sce 6 girenged the flowers, slender, slightly recurved. The calyx-tube is twice as broad as long, or eer the five subequal teeth itiedrved over the gibbosity of the a, lance-linear, four or five times as long as broad, acute.

The pistil is hairy, the ovary conic, the style equal- ing or slightly exceeding the upper lip, and the stigma capitate, two- 8 ADDISONIA lobed, the lobes not or very little spreading. The disk is represented by only two posterior lobes; these are coherent or panes separated, ovate or oval, with an entire or slightly notched sum This species occurs in the mountainous or hilly country of tropical Brazil, and has been introduced to cultivation, where it exhibits considerable variation, especially as to its hairiness. The specimen here figured was grown at the New York Botanical Garden from tubers collected in the Organ mountains of Brazil by J. N. Rose in 1915 The genus Gesneria, with which this species has commonly been associated, and with which it agrees in habit, contains half a hundred species, distributed from the mountains of Brazil westward into the Andes and northward through Colombia into the West Indies. They favor shaded locations in rich woodland soil and amidst decaying vegetation. In the Andes they usually occur among begonias, oxalis, and terrestrial orchids, as well as with other gesneriads. They usually occur in colonies and, with their handsome scarlet flowers, form showy small patches against the forest hillside. From Gesneria Decaisne separated the genus Dircaea chiefly on the basis of its long upper lip, which conspicuously distinguishes it from the true gesnerias. With this view the present writer feels constrained to agree. H. H. Russy. EXPLANATION OF Pate. Fig. 1.—Plant, much reduced. Fig. 2.—Flowering stem. Fig. 3—Flower, front view. Fig.4—Stamens.

The stems are gla below and pubescent above, becoming somewhat tawny- ee ' tomentose in the inflorescence. The opposite leaves are green and nearly glabrous above, and Suds with a grayish-white tomentum n the under surfaces. They are two to six inches long, ovate- lanceolate or lanceolate, acute or acuminate, and have toothed margins. ish Leas Many cl preh of several flowers on short tomentose pedicels make up the curving panicles, which are three to seven inches long. ‘The small pubescent rere) has stag ate lobes. The corolla i is one half to three quarters of an inch long, the tube cylin- c, the four spreading lobes rounded. ‘The four short stamens are attached slightly above the middle of the corolla tube. ‘The short style is tipped with an ovate stigma. The two-celled capsule is less ies an inch long. The summer lilac, or butterfly bush, is one of the shrubs requiring some protection if cultivated very far north, but in our climate is prac- tically hardy. Although killed back to the ground during a severe winter, it recovers strongly the next spring, and sends up new shoots which flower the same season. Plants in the New York Botanical Garden hold the green wood until the first of February of an average winter. Its wide-branching habit, the grace of its panicles of lilac flowers with deep yellow eyes, its delicate fragrance, and the white- ness of the under side of its leaves, make it a very valuable shrub for late summer and early autumn. The varieties Veitchiana and magnifica are even more attractive. The genus Buddieia is quite extensive from Texas throughout tropical America, and in China and Japan, but is represented in cul- tivation by only a few species. B. Colville, B. officinalis and B. astatica are not hardy, but are grown under glass. The last is a white-flowered kind which is grown as a winter cut flower and is 10 ADDISONIA particularly effective displayed in large vases. Our illustration of B. Davidi was made from a plant which has been in the fruticetum of the Garden since 1903. The plant is readily propagated by seeds, or by cuttings of the old or new wood. This species was among the plants sent from the mountains of central China to the garden of the Paris Museum, in 1869, by Pére Armand David, a Lazarist missionary, and was described with others of Pére David’s plants by Franchet in 1888. Previous to this latter year it had also been found by Dr. A. Henry, whose herbarium is preserved in the New York Botanical Garden. In this collection is a specimen collected by him in the province of Hupeh. KENNETH R. BOYNTON. EXPLANATION OF PLATE. Fig. 1—Flowering branch. Fig. 2.—Flower, X 2.

An epiphytic orchid with erect leaves, and a pendulous raceme of seedy 5? flowers. The pseudobulbs are ovoid, up to three or four inches long, deeply furrowed, and usually two-leaved. The elliptic ppl up to fifteen inches long and four inches wide, are gradually narrowed at both ends, at the base into a short petiole or stalk, at the apex into an acute point. ‘They are ac on ASoth surfaces, with three to five primary nerves. “The acem e of a dozen or more spreading flowers, is pendulous, up to a foot long and with a stalk of about the same length, which sie from the base of the pseudobulb. The flowers, about an inch and a quarter across, are on curved stalks, with the column and lip turned down. The sepals and petals are pale straw color, marked with reddish brown. ‘The dorsal: goes is broadly oval, about one half inch long, with the obtuse apex recurved. The ie sepals, somewhat reflexed, are about three diartes of an inch long, and, when spread out, oblong and a little over a half inch ie: the margins are s petals, adnate to the base of the column on one side, are about o quarter of an inch long. The ivory white lip, about a half st long and of odd and unusual shape, is attached to the end of the column foot and follows the curve of the column with which it forms asemicircle. It is laterally compressed, its sides erect and touching at the middle, free at the base and forming two blunt horns. At about the middle of the lip on each side is an obliquely transverse ridge ending in a slender curved horn; the apex is channeled, with a recurved tip. The curved column is about three quarters of an inch long, slender, somewhat dilated above, and with a short reflexed horn on each side; in color it is similar to the sepals and petals. The plant from which the illustration was prepared was obtained in Mexico in 1903, flowering in the conservatories of the New York Botanical Garden for the first time the next year. The genus Gongora, comprising about twenty-five species, is dis- tributed from Mexico to Peru and Brazil, with one species in the island of Trinidad. It is of the tribe Gongorinae, to which also 12 ADDISONIA belong the Holy-Ghost flower, Peristeria elata, and the genera Coryanthes and Stanhopea, both with odd-shaped and unusual owers Gongoras are of easy culture, usually flowering quite freely. When growing vigorously they require considerable heat and plenty of water, but in the winter, when at rest, little water is needed, and they should be kept in a shaded cool moist house. GEORGE V.

Hichlam, and flowered in the New York Botanical Garden May 4, 1915. This species was first described as a Cereus, but in its habit, flowers and fruit it is very unlike the true species of Cereus, of which the well-known greenhouse species, Cereus Jamacaru, is a good representative. Werckleocereus glaber is a near relative of W. Tonduzii, which in 1909 Britton and Rose made the type of a new genus. This latter, a Costa Rican plant, has also previously been known as a species of ereUus. Werckleocereus in its habit and stems resembles Hylocereus, but possesses very different flowers and fruits. In Hylocereus the ovary and fruit is covered with large foliaceous scales without spines or bristles in their axils. Weberocereus is another related genus bearing similar scales on the ovary, but only hairs are found in the axils; then, too, the ovary is not tuberculate and the fruit is not spiny. J. N. Ross.

It was collected and remained out of the soil fully two months. The genus Dudleya contains about sixty species, all confined to the west coast of North America, extending from northern California to the southernmost point of Lower California. A few of the species extend inland, one or two being found in Arizona. ‘They prefer, however, sandy shores and rocky cliffs, often coming directly under the influences of the ocean spray.

Its foliage, at first of a rather bright green, soon becomes darker, and finally, when the cold of fall arrives, turns to a beautiful bronzy hue which persists in this latitude as long as the leaves, usually well into the winter. When in flower, and it flowers continuously from June to November, it is one of the handsomest of shrubs, the old rose of the calyx and the flush on the corollas making a striking combination with the rich green of the shining leaves. In this latitude it is almost evergreen, and further south would perhaps prove to be one of the best of evergreen shrubs. It is essentially 18 ADDISONIA hardy in the vicinity of New York, some of the smaller branches occasionally killing back Abelia grandiflora is of garden origin, a reputed hybrid between Abelia chinensis and Abelia uniflora, inheriting its evergreen ten- dencies from the latter parent. It is frequently offered for sale under the name of Abelia rupestris or Abelia chinensis, considered by many synonymous. Of easy culture, it prefers a well-drained soil and a sunny sheltered situation. The genus Abelia, confined to the northern hemisphere, contains about twenty known species, distributed mainly in eastern and cen- tral Asia, with one in the Himalayas and two in Mexico. It is closely related to Linnaea, with which it is united by some botanists. GrEorGE V. NASH. EXPLANATION oF PLATE. Fig. 1.—Flowering branch. Fig. 2.—Flower, opened.

It was first made known to botanists by Plumier in his “ Description des Plantes de l’Amerique ”’ 53, plate 70, published in 1693, under the name Saururus humilis, folio carnoso, subrotundo; he had it from the French Antilles, but does not say from which island; he records the French names ‘‘ queué de lezard”’ and “ pourpier de bois” as applied to it; according to Father Duss in “ Flore phanérogamique des Antilles francaises,” it is known as ‘‘ queue-de-lézard” in Martinique. It has been recorded from Bermuda, but the Bermuda 20 Anoionaay plant proves to be different and should be called Peperomia spt ZB trionalis S. Brown. The genus Peperomia consists of more than six hundred speciege ie mostly inhabitants of tropical America, but some occur in the Old World. The plants grow readily and often luxuriantly in moist — greenhouse cultivation and are readily propagated by catteg The nearest relative in the northern flora is the common Lizard’s- tail of eastern North America, Saururus cernuus Linnaeus. Our illustration was made from a plant collected in Porto Rico by N.L. Britton and J. F. Cowell in 1906, which has since frequently flowered at the New York Botanical Garden. N. L. Brirton.

It is at its best in July and August, and is truly the forerunner of the hosts of goldenrods, asters and other composites which in late August and September give our meadows, woodlands and swamps such an amazing amount and variety of color. Neglected pastures and old abandoned fields in the uplands are its favorite places of abode, but it is not as critical as some plants are, and is to be found in abundance in almost any kind of dry, sunny location. However, it is not properly a plant of the coastal plain of New Jersey and is there wanting or very local. Originally described by the English botanist Aiton from a small specimen collected by Solander near Hudson Bay, the range of this species is now reported to extend from New Brunswick south 22 to North Carolina and Tennessee and west to Missouri and Sas katchewan. ‘There are a number of closely related species, espe- cially in the southern parts of the United States, and it is aia that these have to some extent at least been confused with the present one, The botanist who named this plant thought it bore a resemblaael to some species of rush (Juncus), and so gave it the specific name — it bears.

A perennial marsh or aquatic herb, very variable in size, with glabrous foliage. ‘The stems (rootstocks) are underground, with more or less elongate branches that often bear tubers. aves are erect or nearly so, commonly one to three feet tall; the petioles taper gradually upward from the stout partly sheathing bases i i i he base of the flowering stem; t . The stamens are usu numerous, with pale, filiform or subulate, filaments and ovoid or ameter or rarely larger. ‘The achenes are about an eighth of an inch long; the body is obovate or cuneate, but inequilateral, broadly winged, especially at the top; the horizontal beak has a slightly declined or curved tip. This arrow-head has a very wide geographic distribution, ranging from New Brunswick and Nova Scotia to British Columbia, south- ward to Florida and California, and through Mexico to Central 28 ADDISONIA America. The plants grow partly submersed in water, on moist or muddy shores, or on sandy flats. Although varying greatly in size, the most conspicuous variation is in the leaf-blades. These range from very inconspicuous organs with narrowly linear lobes to conspicuous objects with deltoid lobes, the whole blade sometimes assuming a deltoid-reniform outline. Plants with these large leaves often take complete pos- session of swamps, covering extensive areas with their leaves, overtopped during the flowering season by the panicles of white owers. For many years our plant was confused with one of similar habit native in Europe. In the first decade of the last century the American plant was definitely separated from the other. Then for about a century this plant was renamed many times, chiefly on account of the great variability in the form of the leaf-blades. This type of variability is very common in many aquatic plants, and it is now understood that these various forms represent only a single species. The starchy tubers of the arrow-head were formerly extensively used by the North American Indians for food. ‘The plant has been exterminated in many places, both by the advance of civil- ization and by the introduction into ponds, lakes, and streams of certain fish that live largely on the young plants of this and other aquatics, Joun K.

Sp. Pl. 860. 1753. A dioecious, erectly branched, maritime shrub up to ten feet high, having a slightly resinous character, the branches angled, at least the younger parts minutely scurfy. The leaves are numerous, alternate, dull pale green in color, smooth and of a thickness that gives them a firm quality; they are one to three inches long, one to two inches wide, obovate-cuneate, irregularly angular-dentate above and short-petioled or, on the upper branches, narrower as well as sessile and entire. ‘The heads are small and many-flowered, those of the staminate plant somewhat globose and mostly clustered at the ends of leafy branchlets, those of the pistillate plant more oblong and loosely paniculate; the scales of the involucre are imbricate and glutinous. e flowers are yellowish white and tubular, those of the pistillate plant filiform. The pappus is white, capillary, and in the fruiting plant copious and elongated. Although this maritime shrub thrives under cultivation in inland gardens, its natural home is the salt marsh and along creeks and rivers that receive the tides. Only infrequently does it stray beyond saline influences. Its range is the long strip of seaboard from Massachusetts to Florida and along the Gulf to Texas, and it occurs also in Cuba and the Bahama Islands. A closely related species is found in Bermuda as well as near the coast in our southern states, and many others belong to the west and southwest and the Pacific states, some of them inhabiting arid regions, others the richer soils of water courses and even of mountain woodlands. The genus, which is a large one, embracing some three hundred species, reaches its highest development in South America. Some of the species are herbs, and others are herbaceous from a woody base. The pencil bush is less woody above than many of our strong undershrubs of swamp and woodland, its upper parts and inflorescence being soft and pliant. It is thus a strongly indi- vidualized form in our vegetation and of very characteristic appear- ance, especially in those situations where it groups itself in greatest abundance, for few other shrubs, or often none at all, are fitted to accept the saline conditions that are its choice. By this it is drawn 30 ADDISONIA to the attention of those whose occupations are along the tidal rivers and bays, and in some districts it is familiarly known to the bay men as Marsh Elder, colloquialized to ‘‘ Mash Elder.” The flowers are inconspicuous and do not attract notice, but at seedtime it becomes a thing of beauty. Its earlier sombre aspect is brightened then into a silvery whiteness, the crowded panicles upbearing myriads of lustrous silky tufts in size and form like an artist’s delicate water-color pencil, whence the name pencil bush. At fuller maturity these tufts become more cottony and finally, with the released achenes, are wafted by the winds over the marshes. This is always very late in the season, for this shrub is one of our latest-flowering species. EUGENE P. BICKNELL. EXPLANATION OF Pate. Fig. 1.—Fruiting branch. Fig. 2,—Staminate flowers.

This plant was probably first collected in Texas about 1830, by Berlandier, and later by Drummond and by Riddell. It grows naturally in the prairies of Texas. It is sold by seedsmen as Centauridium Drummondii, a name given to it by Torrey and Gray, who described it from Drummond’s specimens. In gardens it is treated as a hardy annual, and flowers nearly all summer. Its flowers are of a pleasing golden yellow shade and, owing on long stems, are valuable for cutting.

A shrubby much-branched plant two to ten inches high, the branches slender, reddish, and very leafy. The alternate leaves are narrow, terete, about a quarter of an inch long, and usually at right angles to the branches. The few subsessile flowers are arranged on one side of the terminal branches. The calyx-lobes are five, green, somewhat unequal, an eighth of an inch long or less. ‘The petals are five, spreading, lanceolate, red to pale pink, obtuse to acute. The stamens are ten, and the carpels five, the latter at first erect. This species is common in the valley of Mexico, and is sometimes cultivated by the Mexicans. It is rather inconspicuous, but has pretty flowers; it does not much resemble the ordinary species of Sedum usually seen in cultivation. The illustration was made from a plant obtained by J. N.

A small tree up to twenty feet tall, with the young branches and lower surface of the leaves covered with a dense white tomentum. The leaves are opposite and on petioles one quarter inch long or ments and yellow anthers, are about as long as the petals. The fruit is ellipsoid, green, up to two inches long and nearly as broad. The seeds are reniform-orbicular, compressed. The plant from which the illustration was prepared was obtained in 1902 by exchange with the Royal Botanic Gardens, Kew, Eng- land. Feijoa is a small genus of a single, or perhaps two or three, species. It was at first given the name Orthostemon, but on account of the earlier application of this name to another group of plants the present name was substituted. This species is indigenous to southern Brazil, western Paraguay, Uruguay and parts of Argentina. It is common in the forests of this region, and the fruit is highly esteemed by the natives, although not cultivated by them. About 1890 it was introduced into southern Europe, and it is now cultivated in the Riviera. It was brought to this country from France about 1900, and is becoming quite ex- tensively cultivated in California, where it thrives. Its successful 38 ADDISONIA cultivation seems to require a well-drained situation with a good loamy soil, rich in humus; it will not grow well in heavy clay or light sandy soils. ‘The trees should be set fifteen to twenty feet apart. When mature the fruits fall and must be set aside in a cool place for mellowing before they are suitable for eating; this state is reached when they become slightly softened and begin to exhale a character- istic fragrance. The plant may be propagated by seeds, or by cuttings Bee glass. The cuttings should be about four inches long, of young wood taken from the ends of the branches, and should be placed in clear sand over bottom heat. They may also be propagated by layering. The myrtle family, to which Feijoa belongs, contains about three thousand species, widely distributed in tropical regions, with few in subtropical, and only one, Myrtus communis, the common myrtle, in the Mediterranean region. There are two main centers of distribution, however, one in tropical America, and the other in Australia. The plants of tropical America usually have berry- like fruits, a good example of which is the guava, while those in Australia asarule have dry fruits. The large Australian genus Eucalyptus belongs to this family. Grorce V. Nasu.

According to Gray, it had been cultivated in England as A. bostoniensis, but in this country it has not been used as much as it should be. It has the habit of the well-known Aster Novae- Angliae, and is quite similar to A. oblongifolius, but its involucral bracts are hispid instead of glandular.

It is the type species of the genus Harrisia, described by me in 1909 in the Bulletin of the Torrey Botanical Club (35: 561). It is named in honor of William Harris, Government Botanist and Superintend- ent of Public Gardens of Jamaica, distinguished for his valuable contributions to the knowledge of the flora of that island, which have made its wild plants better known than those of any other of the Greater Antilles. The plant is locally called ‘‘ dildo,” a name applied also in the British West Indies to other columnar cacti. About fifteen species of Harrisia are known, which are dis- tributed from southern Florida and the Bahamas southward to Argentina, eight of them being West Indian or Floridian and seven South American. The fruits of all the West Indian species are edible, containing a nearly white smooth pulp, and very numerous minute black seeds. The plant from which our illustration was made was brought from Jamaica by John F. Cowell in 1904, and has since bloomed several times at the New York Botanical Garden. N. L. BRITTON.

The blades are pedately compound, with five, or exceptionally seven, leaflets at the slightly thickened apex of the petiole. The leaflets are dark-green and glabrous above, p aiecinten and pubescent with short hairs beneath; the blades of the t three upper leaflets are obovate or elliptic-o obovate, usually six to nine inches long, and rather long-petioluled; those of the lower pair of leaflets are much smaller than the others, opores. elliptic, or ovate, and short-petioluled; all the leaflets ong-acuminate at the apex and finely and unevenly serrate. The flowers are borne in many, often numerous, erect, plume-like, narrow panicles, which terminate long peduncles that resemble the petioles. The pedicels are slender, about as long as the calyxes. The calyx is tubular-campanulate, about a quarter of an inch long, with obtuse unequal lobes. The petals are white, much exserted from the calyx, about three quartet of an inch long, spatulate, slightly unequal, with a midrib which divides into several veins in the broader part of the ‘blade. The stamens are nearly twice as long as the petals or more, with thread-like filaments. The anthers are oval, reddish, about one twelfth of an inch long. ‘The fruits are globose, an inch and a quarter to an inch and a half in diameter and smooth. ‘The brown seeds are usually solitary in each fruit. This buckeye was discovered, in what has proved to be about the extreme eastern limit of its geographical range, in the latter half of the nineteenth century. It was first named and described about the last decade (1788) of that century by Thomas Walter, a resident of South Carolina. In 1803 the plant was renamed as Aesculus macrostachya by André Michaux, who also collected it in the eastern part of its range. This name was in vogue in Europe for many years, 46 ADDISONIA The plant has long been in cultivation, having been introduced into gardens in England as early as 1785, or three years before it was described and named, by John Fraser, who made extensive collections of living plants in the southeastern United States. On the one hand, Walter was struck by the size of the flowers, which are smaller than those of the other species he knew, and named the plant accordingly; on the other hand Michaux’s atten- tion was attracted by the much longer and more conspicuous inflorescence than that in the species he knew, and consequently derived his specific name from that character. This plant grows naturally in South Carolina, Georgia, and Alabama, chiefly in the region between the coastal plain and the mountains. It is widely cultivated both in North America and in Europe. It is naturalized in southeastern Pennsylvania, This buckeye is a very desirable ornamental shrub from spring to fall. When not in flower its dense bank of dark-green leaves is attractive and when in flower its showy plumes of white flowers standing against and above the foliage are very conspicuous. The specimen from which the accompanying illustration was made was obtained in 1907 and has been in the fruticetum of the New York Botanical Garden, where it has flowered frequently. It may be propagated from seeds, by side-grafting, budding, layering, or root-cuttings. J. K. SMA.

The plant from which this illustration was prepared was raised in the New York Botanical Garden from seed collected by the writer in a ravine, at an elevation of about 3,000 feet, near Marme- lade, Haiti, in August, 1903; in 1905 he also collected it in the pine- lands at the same place, at an elevation of about 2,500 feet. This interesting plant is also found in Santo Domingo, where it is reported that the tubers are prized by the natives as food and as an article of commerce, in Cuba, and in the Isle of Pines. It has also been collected in Mexico, but whether there native or an introduction is not indicated. The genus Bomarea, comprising over seventy-five species, is distributed from Mexico to Argentina, Chili and the West Indies, 50 ADDISONIA the species here under consideration being the only one known from the last region.

Suppl. 373, 1781. A perennial herb, up to seven feet high, with robust, leafy stems bearing corymbiform panicles of flowers. The roots are long and fibrous. The stems are erect, strongly sgn and hispid, becoming very rough in the inflorescence with spine-like hairs. leaves are nearly two feet long and ae “nities wide, with margins of broad, somewhat mucronate teeth. They are Snseptage and narrowed at the base into slender petioles. The stem-leaves are sessile, tending to be decurrent, with a margin of sharp teeth. They are lanceolate, acuminate, about six inches long and one inch wide. Those on the branches of the inflorescence are still smaller, and very rough. ‘The flower-heads are one inch or more across, sur- rounded by a campanulate involucre of herbaceous bracts, which are purplish at the tip and on the edges. The yellow disk is made up of perfect, tubular flowers, and is surrounded by fifteen to twenty Sistitidte ray-flowers, light-blue or purple in color, and three fourths of an inch long. e flattened achenes bear many simple bristles, and are borne upon a convex, pitted receptacle. The Tatarian aster was first found in Siberia, and later in Japan and China. It grows in its native home on wooded hillsides, In the herbarium of the New York Botanical Garden are specimens collected in Japan by Maximowicz, and on Saghalien Island. Our illustration was made from a plant growing in the flower beds near Conservatory Range No. 1, since 1911. This aster develops its strong stems during the summer, and flowers from late September, through October, until the hard frosts set in, Blooming as late as it does, it adds greatly to the beauty of the perennial border at a time when most of the flowers are gone. It has a tendency to spread by suckers, and is readily propagated by division. Its lasting flowers and long stems make it valuable for cutting. KENNETH R. BOYNTON. EXPLANATION OF PLATE.

A slender vine-like cactus, clambering over bushes, or nearly prostrate, often six feet long or longer, branched, the branches a little less than one inch thick, with four or five low ribs or angles, the depressions between the ribs D ahallow and narrow. ‘The areoles, borne on the ribs, are small and circular, and usually bear a rather stout single spine about one inch long, brownish or straw-colored with a blackish tip, and several short radial spines, sometimes half as long as Ss central one, but usually shorter. ‘The flowers appear singly at one or more of the areoles and are from five inches to about eight inches long; the nearly cylindric tube is about as long as the limb, or a little longer, and about one half an inch in thickness, bearing several short, broad, pointed, ovate scales, similar to those borne on the somewhat tubercled ov ary and with brown felt in their axils; the widely spreading outer perianth-segments are nearly linear, long-pointed, greenish-brown, sie do. to three 2 sone and about one quarter of an inch wide, pink when the inner perianth-segments are nearly as Saag é as the outer nite ani about three times as wide, and abruptly broad-tipped, white, or tinged with pink; the stamens are about two-thirds as long as the ie gaat ts and the style otal wi and a bears a small ovate eae on each ewe. and is usually spineless. When first described in 1854, the habitat of this cactus was unknown, but it was subsequently found to grow in the deserts of Argentina and Paraguay; it is now common in collections of cacti and flowers frequently in greenhouses. ‘The Italian botanist Ricco- bono recognized this plant and some of its relatives as a generic group distinct from Cereus and proposed for them the generic name Eriocereus, in 1909, the same year in which I proposed the generic name Harrisia (see plate 61 of this work); his account, published in the Bulletin of the Royal Botanical Garden of Palermo 56 ADDISONIA appeared later in the year than my paper published in the Bulletin of the Torrey Botanical Club, the name Harrisia thus having priority. I have been unable to verify the citation of the original publica- tion of Cereus Martini, not having been able to learn of the existence of this, the first (and only?) volume of the Annales de la Société d’Horticulture de la Haute-Garonne, in the United States.

An epiphytic orchid. The ae are three to four inches long, bearing two leaves at the summit. ‘The leaves are four to six inches long and about an inch broad, narrowed to a folded base and rather acute at the apex. The panicle i is drooping and is borne upon a scape bearing a few white scales, both the scape and the branches and pedicels of the inflorescence being a dark red. ‘The flowers are about three quarters of an inch in diameter. The petals and sepals ,which are greenish yellow on the outside and red-brown barred with yellow on the inside, are inwardly curved, giving the flowers a somewhat cup-shaped appearance; the lateral sepals are united almost to the apex, forming a narrow body which is two- toothed at the apex; the dorsal sepal is obovate, about a half inch long, rounded at the apex, and narrowed toward the base; the petals are similar in shape and size to the dorsal sepal but with a more narrowed base. ‘The lip is red-brown; at the base is an orbicular transversely wrinkled callus with two ascending obtuse horns; in front of this and immediately above the lateral lobes is another callus of two blunt spreading processes; the lateral lobes = the lip project downward, are incurved, and with revolute argins; the middle lobe has the margin strongly revolute at the base and is provided with a thick transversely rugose callus, the x of the lobe being broadly rounded and strongly reflexed. the pubescent column has on each side, about the middle, a thick and broad flat wing which spreads at a right angle to the column and is about as long as the column is wide. The anther is white with two pubescent processes. The plant from which the drawing was made was collected by J. N. Rose at Corcovado, Rio de Janeiro, Brazil, in 1915, and flow- ered at the New York Botanical Garden. It is an odd member of the genus, the contrast of the outer with the inner side of the sepals and petals giving it a striking appearance. The lip is of queer and unusual shape.

The calyx is clothed with about an eighth of an inch long. The petals are about three aehehs of an inch long, obovate. The fifteen to twenty stamens are shorter than the petals, the filaments flat and glabrous. The Styles are about as long as the stamens. The fruit, black with a slight bloom, has a diameter of about one third of an inch, and contains ae a single nearly globular seed somewhat smaller than the frui This ia while not hardy in the north, is reported to stand about ten degrees of frost and is hardy in the southern states and in California. In the north it should be grown in a cool house, in a compost of sandy loam and leaf-mold. The plant from which this illustration was made was secured by the New York Botanical Garden in 1900, and has flowered and frnited repeatedly. Propa- gation is effected by means of seeds; by cuttings late in summer of ripened wood; and layering, and grafting on the thorn are Sometimes resorted to. Ggorce V. Nasu. EXPLANATION OF Puate.

PLATE. 71 ADDISONIA ROSA “SILVER MOON” ADDISONIA 61 (Plate 71) ROSA “SILVER MOON” ‘¢ Silver Moon” Rose Garden Hybrid Family Rosackaz Rosg Family A vigorous bush with long climbing stems, glossy dark green foliage, and large white partially double flowers. The stems attain adnate to the leaf-rachis, have spreading acuminate free tips, and have the margins with stalked glands. The leaf-rachis, usually more or less tinged with red, bears a few spines, similar to those on the stem but smaller, and rather numerous stalked glands. The glabrous leaflets, which are commonly five, the lateral on stalks an eighth of an inch long or less, the terminal on a stalk much longer, are ovate to nearly orbicular, up to two inches long and an inch and three-quarters wide, and are abruptly short-acuminate; they are lustrous dark green above, paler beneath, the margins crenate- serrate with pointed teeth, usually fifteen to twenty-five on each side. ‘The flowers are borne in clusters of usually two to four, the stalks, which are tinged with red, with stalked glands. The sepals are ovate, acuminate into a long tip, the margins entire or rarely toothed or lobed, the outer surface on the margins and the entire inner surface hairy. ‘The buds are pointed and well-shaped, of a creamy yellow, opening into large flowers, sometimes five inches in diameter, of a pure white sometimes faintly tinged with yellow; the outer petals are broad and spreading, the inner smaller, undulate d incurved, partially concealing the central mass of bright yellow an stamens, the whole producing a flower of charming beauty. This rose was originated by Dr. W. Van Fleet, phsyiologist in the Bureau of Plant Industry, at Washington, D. C. In ere to an inquiry Dr. Van Fleet writes as follows: ‘“‘ The climbing rose Silver Moon was raised in 1906 from an unnamed hybrid of Rosa Wichuraiana X devoniensis pollinated with the Cherokee rose (R. laevigata). I have grown many seedlings of Wichwraiana (type) X Cherokee, but none turned out as hardy and showy as Silver Moon. ‘The influence of devoniensis, a large white-flowered and quite hardy form of Rosa odorata or Tea rose, appears to have been highly beneficial in the case of Silver Moon, though the direct cross of Wichuraiana and devoniensis has little merit as a garden plant, as it is a shy bloomer, but vigorous in growth and with good foliage.” Dr. Van Fleet adds that Silver Moon bloomed the second year from seed. 62 ADDISONIA It would appear from this that Rosa devoniensis has been the blending element, harmonizing in “Silver Moon” the best in Rosa Wichuratana and Rosa laevigata, giving us in this production of Dr. Van Fleet a rose which holds a unique position among the climbing roses hardy in the north; for it adds to our gardens one with all the beauty and attractiveness of the Cherokee, not hardy in this latitude, combined with a vigor which defies the rigors of our northern climate. The large semi-double flowers and lustrous deep green foliage make it a striking object anywhere. It was shown in 1908 at an exhibition of the Horticultural Society of New York held in the Museum building of the New York Botanical Garden. With the permission of the exhibitor the material exhibited was made into cuttings, and it is from this source that the plants at the New York Botanical Garden have been derived. The illustration was prepared from one of these plants. GEORGE V. NASH.

Chron. 67: 512. 1890, This epiphytic orchid has furrowed pseudobulbs usually three to six inches long, rarely longer, and up to one half inch broad at the middle and tapering at the base; they bear at the apex two or three leaves which are oblong-elliptic, rather acute, and measure three to five inches long and an inch to two inches wide. From the apex of the pseudobulb arises a single spike of four to eight flowers, which are usually about two inches in diameter. ‘The spreading sepals are yellowish white, marked, especially toward the base, with spots of violet-purple, the dorsal sepal an inch to an inch and a quarter long, ovate and obtuse, the lateral ones a little smaller, ovate-triangular and shortly acuminate, falcate, and forming a prominent chin at the base. ‘The erect petals, similar to the sepals in color and size, are broadly oblong or obovate, acute, with the margins undulate toward the base. e greenish fleshy lip is about as long as the petals and is distinctly three-lobed; the erect th three furrows below and two above. ‘The column is nearly a half inch long, greenish-white, the front violet-purple, the apex with two sharp reflexed teeth.

The inflorescence is in terminal, many-flowered cymes, the pubescent pedicels bearing delicate pink flowers about one half inch across. ‘The glandular-pubescent hy- panthium is broadly campanulate, somewhat four-sided, faintly eight-nerved, bearing upon its margin the sepals, petals, and stamens. There are four short, triangular sepals, alternating with the four petals. The petals are oval, obtuse, and obliquely placed. There are eight stamens, the filaments of which are short, and bear yellow, elliptic anthers; the four of these opposite the petals are smaller and darker colored than the other four. The ovary, en- closed by the hypanthium, is four-celled, many-ovuled, and sur- mounted by a short style and inconspicuous stigma. The capsule is glabrous, with four cells containing elliptic seeds. This is one of the four or five species of the Mexican and Central American genus Centradenia; two others are often cultivated, C. grandifolia, with larger, colored leaves, and C. inaequilateralis, with smaller one-sided leaves. Planchon described our species in 1849 from a plant grown in the establishment of Louis Van Houtte, the famous Belgian horticulturist. In this species the reduction of the anther-appendages, which are so pronounced and curious in many plants of the Meadow-beauty family, is noticeable; the other cultivated species have prominent appendages. é Our illustration was prepared from a plant growing in the New York Botanical Garden greenhouses since 1902, coming originally from the National Botanic Garden at Washington. Although it lacks the richly colored foliage of C. grandifolia, its many flowers and red stems make it very attractive. It can be grown easily 66 ADDISONIA in the greenhouse, is readily propagated by cuttings, and blooms nearly the whole year through. KENNETH R. Boynton. EXPLANATION OF PLATE. Fig. 1.—Flowering stem.

An aquatic plant, inhabiting shallow water, rooting in the mud, its stems stout, one to two feet long, or longer, sending out many roots from the nodes, and usually branched. e leaves are alternate, rather dark green; the petioles are stout, sheathing, from about four inches to over a foot long and half an inch thick in texture, orbicular, oval or obovate, from two to six inches long, very delicately and closely parallel-veined, with a tipped or some- times notched a y or abruptly narrowed base and a short or long style tipped by a small stigma. The fruit is a many-seeded capsule; when ripe the fruiting spike curves downward and becomes submersed. The plant inhabits lakes, ponds and rivers in Jamaica, Cuba, Hispaniola, and Trinidad, and is distributed on the continent from Nicaragua to Bolivia, Venezuela, and Uruguay. In Brazil, it 1s known under the names Culhereira and Camalote. It is related to the Floating Water Hyacinth, Piaropus crassipes, also native of continental tropical America but probably not of the West Indies, which has been introduced into Florida, Cuba, Bermuda and Jamaica, and has become one of the most troublesome of aquatic weeds, often blocking rivers and ditches by its vigorous growth, or 68 ADDISONIA completely covering lakes and ponds; this has similar, somewhat larger flowers, but its petioles are inflated and bladder-like, enabling the plant to float freely. Both species show trimorphism, having stamens and styles of three different lengths in different flowers. Both are in cultivation under glass at the New York Botanical Garden, and are also grown here in a pond at the herbaceous garden during the summer, where the first touch of frost kills them promptly. The plant here illustrated was sent to us from Fairmount Park, Philadelphia, in 1905 N. IL. Britron. EXPLANATION OF PLATE. Fig. 1.—Flowering stem. Fig. 2,—Flower opened. Fig. 3.—Leaf.

The stems of this perennial herb arise from creeping rootstocks; they are two to eight feet high and are cinereous puberulent, pubescent, or hirsute, The alternate leaves are very numerous and decrease gradually in size from the base to the top of the stem. They are lanceolate and strongly three-nerved and the lower are sharply serrate and petioled, while the upper are less serrate or nearly entire and sessile; they are minutely pubescent or rough above and short-hairy beneath, and usually are two to six inches in length and one third of an inch to an inch in width. ‘The heads are very numerous, short-stalked and secund on the spreading or recurved branches of the ample pyramidal panicle. Each in- : : ; an uti ll and blunt or slightly oohited and rather thin. The achenes are glabrous or slightly pubescent. This is the most abundant and best-known species of golden-rod in many sections of the eastern half of the United States, and often thrives so well that it might well be regarded as a weed. It flowers from August to November and is found in various situations, but prefers dry soil and a sunny exposure. It occurs from Maine to Georgia and west at least as far as Nebraska and Texas, while plants from still further west are very closely related. Its botanical history commenced before 1728, for in that year Martyn (Hist. Pl. 14. gl. 14) published a good colored plate of the Plant, under the name “ Virga aurea altissima serotina, panicula Speciosa patula”” which name was taken by him from a previous Publication by Isaac Rand, which I have not seen. Later on, in 1753, Linnaeus seems to have had a clear conception of the species. At any rate he kept it distinct from another species of more northern Tange, which he named Solidago canadensis. Later botanists over- looked the distinctions between these species and as a result the Plant we are now considering passed as Solidago canadensis for 70 ADDISONIA many years, and it is under this name that it is usually found in local floras and lists published before the last ten years. True Solidago canadensis, which in the vicinity of New York is an un- common species, is however readily distinguished by its markedly smaller involucres; in addition it strongly tends to being less pubescent and to having more sharply serrate leaves. The illustration was prepared from a plant growing wild on the grounds of the New York Botanical Garden. KENNETH K. MACKENZIE. EXPLANATION OF PLATE. Fig. 1.—Inflorescence. Fig. 2.—Leaf.

The particular plant from which the illustration was made is now nearly ibe ae high, is of a spreading rather bushy habit, and blooms ago 6 : long season each winter. Its attractiveness lies almost wholly the beautiful clusters of stamens. KENNETH R. BOYNTON. —Flower. EXPLANATION oF Pate. Fig. ‘ _—Flowering branch. “ahs =i —_-Pistil.

Ref. Bot. pl. 298. 1871. This is a glabrous perennial with fleshy dotted leaves and ample clusters of white flowers tinged with red. stems are a foot or two high, fleshy. The leaves are entire, opposite, decussate and widely spreading, the upper surface an apple-green with numerous pustular dots, the lower surface paler; the lower leaves are two to three inches long, obtuse, sometimes notched at the apex, narrowed abruptly at the base into a flattened petiole which is shorter than the blade; the roundish uppermost leaves are smaller and sessile or nearly so. The inflorescence is a thyrse of numerous flowers, the branches ascending. ‘The flowers are about three eighths of an inch in diameter, the parts in fours; the calyx is small, the lobes short and deltoid; the corolla is of lanceolate and widely spreading acute petals a little less than a quarter of an inch long, white tinged with red, the color much darker in the bud. The stamens are a little shorter than the petals, as are also the carpels. This is a charming little plant for the cool greenhouse, responding readily to fair treatment and producing for a considerable period a wealth of star-like blossoms. The illustration was prepared from a plant which has been in the collections of the New York Botanical Garden since 1901, secured in an exchange with the Royal Gardens, Kew, England. The genus Crassula, confined to the Old World, comprises about two hundred known species, mainly of the southern part of Africa, with a few in its tropical parts, and scattered representatives in _ Abyssinia and the Himalayan region. The members of this genus are commonly perennial herbs or shrubs, few being annuals. Their flowers have the parts mostly in fives or more, the species here considered being unusual in having the parts in fours, from which circu ce is derived its specific name. esr . G#ORGE V. NASH.

PLATE: 80 ADDISONIA ASTER CORDIFOLIUS ADDISONIA . 79 (Plate 80) ASTER CORDIFOLIUS Blue Wood Aster Native of the eastern United States and Canada Family CARDUACEAE THISTLE Family Aster cordifolius I,. Sp. Pl. 875. 1753. A perennial herb, commonly two to four feet high, with flexile freely branching stems that are glabrous or nearly so. The leaves are dull green, thin, somewhat rough to the touch on the upper surface, and are rarely without some small scattered hairs both above and beneath. ‘Those of the main stem are heart-shaped and acuminate, with serrate margins, the blades borne on slender stalks that are minutely ciliate. Upwardly the leaves become gradually shorter stalked and less deeply cordate, on the stems taking an even margin and narrowed sessile base. The numerous heads, in panicled clusters, are from one half to three quarters of an inch broad, their involucral cup cylindric, becoming slightly broadened above, and composed of linear-oblong bracts having greenish tips. ‘The rays, ten to twenty in number, are, in different plants, of various, usually pale, shades of violet or blue. The small clusters of disk flowers are yellow changing to purplish rose color. Perhaps no other groups of our native plants have found clearer reflection in the poetry and literature of our country than the asters and goldenrods, and yet, outside of botany, the very numerous members of these companion groups remain little known. The aster of our illustration finds its place somewhere between the more showy kinds and the host of smaller white flowered forms that, more especially, are collectively known as Michelmas daisies. It is of wide range, from New Brunswick to Minnesota, and south to Missouri and the mountains of Georgia, and in its places of abund- ance is a prominent although unostentatious member of its tribe. Its flowers are very numerous, and more than in most of our asters are disposed to top the leafy stems and branches in dense clusters. The plants, too, like to come together in extensive groups, by this habit producing massed effects of color along thickets and wood borders that become a feature of the late autumn; for it 1s among the later asters and well resists the advancing season. a This is one of those plants whose variations take it into wide divergencies, and even confused relationships with allied species, giving problems about which botanists are not yet agreed. So 80 ADDISONIA variable a plant may be conceived of as having place in its genea- logical system at the growing end of its particular branch, impelled at that point of intensified unfoldment to far greater energy of variation than are more quiescent species that, stranded beside the main current of their family course, are left without the impulse to go forward into ready or tenacious deviations. Even more than this species other asters, notably the white wood aster (Aster divaricatus I.) and the New York aster (Aster Novi- Belgit I.) are prone to this truancy from the parental bounds, and the genus as a whole, with its multitude of related forms and its many subgeneric offshoots, may well be viewed as being itself terminal in position on some progressive branch of a strong family stem. The flowers of the blue wood aster by an occasional striking change appear with rays of purest white. EUGENE P. BICKNELL. EXPLANATION OF Pate. Fig. 1.—Flowering stem, Fig. 2.—lLeaf.
