The majority of the new fungi, ooo in the following pages, have been received from the West Indies. A few are from Lee se Africa and elsewhere. Marasmius scandens is a parasite n Cacao in West Africa, and causes considerable damage to the tanta Another new fungus of interest is Diplodia rapax, which appears to be parasitic on the branches and roots of Hevea brasiliensis ; this fungus was received almost simultaneously from Singapore and from West Africa. Two of the fungi described may be parasitic on insects, viz.: Scleroderris gigaspora, on scale insects on the leaves of the orange ‘tree, and Septocylindrium suspectum on the bodies of “Frog-hoppers.” Both these fungi require investigation under natural conditions as, if their true parasitism should be established, they may prove to be of some economic importance.

Writing of this species in the Gardeners’ Circaisle | in 1859, Fortune states that R. Championae, Hook., was the only other species known, at that date, to inhabit China. It should be men- tioned, however, that he did not include the species belonging to the section Azalea.

Falconeri forms a strong connecting link with the sub-Himalayan types of Sikkim and Assam. In view of the remarkably local distribution of most of the Chinese and Himalayan Rhododendrons, it is very surprising to find species so evidently and closely allied, separated by some fifteen degrees of longitude and by several stupendous mountain ranges.—E, H.

Yunnan, cuca: For shade inside the plantation they are too bulky and the root system is too wide and dense. 210 “ The Manihot species, except Manihot Glaziovii, which is of a doubtful value as a rubber producer, grow too low. To this it must be added that the branches of all species of Manihot are very brittle, and that these trees prefer soil and climatic conditions which do not suit the cacao tree. “ Castilloa elastica, therefore, remains as the rubber tree most likely to give satisfaction, and it is probably also this tree which has most frequently been tried and recommended. A native of the same countries as Theobroma Cacao, its general climatic require- ments are the same. As regards soil, Castélloa thrives well on any good cacao land, but it is less particular, and will grow well on both lighter and heavier soils when the drainage is satisfactory. Castilloa elastica, like the cacao, prefers much water and atmospheric humidity, but it is very susceptible to damage through the least stagnation of subsoil water and acidity of soil. “ Although Castilloa in its native country is found growing in the forests it is not really a forest tree, but a ‘Tree weed’ as it has keen termed by Mr. O. F. Cook, in his report on ‘ The Culture of the Central. American Rubber Tree,’ Washington, 1903, by which term he understands a tree which can not grow up in the natural forest, but will develop rapidly on clearings, old garden sites, &c., where the slower-growing forest trees follow and surround it. In cultivation it is able to develop to perfection without shade, even on rather dry land, though it grows more rapidly when slightly shaded during the first years. oe On fair cacao land, Castilloa will reach a height of 25 to 30 feet within the first 4 years, and it is only when the tree is about 3 years old that it commences to develop permanent branches ; before this the only branches developed are pseudo-branches which, like the leaves, are shed every year. The pseudo-branches carry all the foliage of the tree, and when the growth is healthy the development both on the main stem and on the permanent branches is very rapid. The permanent branches remain few, but with their abundance of pseudo-branches, they form a dense crown affording good shade. “In localities where dry weather prevails during the months of March and April, the habit of Castilloa is decidedly deciduous, and it drops all its pseudo-branches during a short period ; while in districts where the spring weather is damp the change of foliage is gradual. The fact that the tree may thus stand naked for some time forms the principal objection to its usefulness as a shade for cacao, whilst the abundance of mulch formed by its leaves is a point in favour of its planting. “On fertile cultivated land Castilloa is a surface feeder, and develops very heavy roots, which run far, without however forming a dense system, as is the case with Hevea. When manure is dug down for the benefit of the cacao trees, the roots of both cacao and rubber develop equally well in it, very differently from what is the case when manure is dug into land planted with bananas and cacao, in which case the banana roots grow rapidly and densely into the manure to the exclusion of the cacao roots. It would appear that the roots of cacao and Castilloa elastica agree well in the same soil. The facts that the crop of rubber removes practically nothing i 211 from the land, and that the evaporation of water from the Castilloa tree is likely to be less than from ordinary shade trees, speak in favour of its extensive planting among cacao. “It has often been stated that Castilloa elastica, under cultivation, will not yield rubber in paying quantities. It would go beyond our object on this occasion to enter into a description of the methods and economies of rubber tapping; we therefore limit ourselves to stating that, if the right varieties be chosen for planting, excellent returns may be obtained.” Guayule Rubber.—An account of this Mexican source of Rubber, derived from Parthenium argentatum, A. Gray, was published in the Bulletin 1907, pp. 285-294, with a further note in the Bulletin for 1908, p. 255. In 1907 some seeds of Parthenium argentatum and also of P. incanum,—a species sometimes confused with the rubber- yielding plant (cf. K.B. 1907, p. 294)—were received from the United States Department of Agriculture. The plants of Guayule raised from these seeds are now about 18 imches high and in flower, the stem is woody below and the silvery leaves, 2 inches long, are lanceolate, entire or in a few cases irregularly lobed or toothed. The plants of P. incanum have glaucous or silvery hawthorn-like leaves and in their crenate lobation differ markedly from the leaves of P. argentatum where the lobes are sharply angular. Through the kind offices of Mr. Reginald Tower, H.M. Minister, Mexico, two consignments of the seeds of Parthenium argentatum were received at Kew in March and April of this year. The first consignment was sent to Mr. Tower by Mr. J. E. Kirkwood of the University of Montana, Missoula, the author of a paper on the “ Propagation of Guayule by seeds” in the American Review of Tropical Agriculture, vol. i, No. 2, February, 1910, pp. 34-43. he second consignment of seeds was sent by Mr. Tower from Mr. G. Fleming of the Hacienda de Cedros, Mazapil, Zacatecas. The bulk of the seeds so received has been distributed to Mysore, Baroda, Poona, Lahore, Ceylon (Hakgala), Sudan, Pretoria, Nairobi, Queensland, Port Darwin, Adelaide, Sydney and the Antilles. The germination of the seeds retained at Kew has been good ; the plants raised from the later sending in April are now 6 inches high and bear somewhat silvery, oblanceolate, slightly lobed leaves 3-4 in. long. The older seedlings are a foot high, the whole plant being covered with a fine silvery-grey tomentum; the leaves are 2-5 in. long, narrowly lanceolate and irregularly lobed with angular acute or subacute lobes. Some of the plants, which are already shewing flower heads, have been placed in the Succulent House. a In the Bulletin 1908, p. 255, a despatch from H.M. Minister, Mexico, was published, in which the Guayule Kubber industry did not appear to have a very bright future; a further despatch received from Mr. Tower, early last year, indicates that the industry is still in a flourishing condition. e Mexican Rubber Exploitation Company now have a large Guayule factory established in the State of Coahuila and with a new process for the extraction 212 of the rubber they have confidence in the successful development of the industry. According to the statements made by the head of the company, “ Experiments had now satisfied them conclusively that the Guayule plant reproduces itself naturally and abundantly. The roots of the shrub extend to a considerable distance in a directions, and new shoots spring from the roots, growing satis- factorily even after the present shrub has been cut down. Opinions differ about the life of the plant and as to the suitable time for cutting, but the generally accepted view is that between ten and twenty years must elapse before maturity is reached and the plant contains sufficient rubber for commercial purposes.” A further despatch from Mr. Tower, printed below, gives some additional in- formation as to the successful development of the Guayule industry. Mexico, _ March 23rd, 1910. IR, Wir reference to my Despatch of this Series, No. 52 of December 3rd, 1906, and subsequent reports concerning the Guayule rubber industry in Mexico, I have the honour to report the following which has been published in the “ Mexican Herald” of the 19th instant :— “ More attention will be paid to the culture of Guayule during 1910 than in any previous year. Statistics and reports in the Department of Fomento show that the increase in the production of this rubber-producing shrub has been greater than any other product of the northern section of the Republic. “ A few years ago the shrub only brought $25.00 (say £2 10s.) a ton in the open market. This price has risen very rapidly, as the splendid properties of the plant have become better known, until at the present time it is selling for $150.00 (say £15) a ton. “ At the present price the profit to the grower is large and is resulting in a greatly increased acreage in the Northern States of the Republic, where the plant seems to do the best. The estimates in the hands of the Department of Fomento indicate that the acreage for the present year will be more than 30 per cent. greater than that of last year.” ; I have, &c., Signed) RecginaLp Tower.

BULLETIN MISCELLANEOUS INFORMATION, No. 7.] (1910. XXXI.—EPACRIS HETERONEMA, Labill, AND E. DUBIA, Lindl. (With Plates.) O. STAPF. In Flora Australiensis (vol. iv., p. 239) the area of Epacris heteronema, Labill., is described as including Tasmania and parts of Victoria and New South Wales. The Tasmanian specimens, with one exception, are referred to typical EL. heteronema, the remainder to a “var. ? planifolia,” whilst, in a note, #. dubia, Lindl., is said to be possibly a garden variety of E. heteronema. With respect to this FE. dubia, certain questions have been referred to Kew Mr. J. H. Maiden, Director of the Botanic Gardens, Sydney, New South Wales, with a view to finding out what Lindley’s plant might be. They were occasioned by a, note in the Kew Bulletin, 1909, p-. 228, in which an Epacris that had flowered at Kew was with some reserve referred to E. dubia, as var. subreflexa, It was clear from the note that in E. heteronema, in the sense of the Flora Australiensis, we had to deal with an ill-defined type which required further and closer examination. ‘This examination has been carried out and the results are embodied in the subjoined remarks. Epacris heteronema was discovered by Labillardiére in Recherche Bay in the extreme south of Tasmania, and described and very well figured in his Novae Hollandiae plantarum specimen (vol. i., p. 42, tab. 56) in 1804. One of Labillardiére’s original specimens is at Kew, and there can be no doubt as to the plant which he meant. Mr. Maiden collected it again in the “locus classicus ” two years ego. The other localities of HE. heteronema, Labill., represented at Kew, are :—South Port, about 10 miles north of Recherche Bay, Mt. La Perouse, north-west of Recherche Bay, Port Davey, on the south-west coast of Tasmania, and “high healthy plains between the Franklin and Gordon Rivers near Macquarie Harbour,” about 50 miles north of Port Davey. In 1833 an “ Epacris heteronema” was figared in the Botanical Magazine (tab. 2357), from a specimen grown at Kew, and it was stated that the plant had been introduced by A, Cunningham from the Blue Mountains (New South Wales). This “ £. heteronema ” of the Botanical Magazine was soon afterwards recoguised by A. P. De Candolle as,a form distinct from the Tasmanian plant and (17122—6a.) Wt. 92—428, 1375, 8/10. D&S. 214 - described in his Prodromus (vol. vii., p. 762) as var. “6 ? subreflexa”’ with the additional observation “An species propria.” In the Flora Australiensis De Candolle’s name does not appear ; but the Botanical Magazine figure is quoted under “var. ? planifolia” of E. heteronema. The specimen from which this figure was drawn is preserved, and it is quite clear that it agrees absolutely with the plant referred to Epacris dubia, as var. subreflexa, N.E. Br., in the Kew Bulletin for 1909. But from a comparison of the flower it is equally evident, first that the cultivated plant is specifically identical with the specimen collected by A. Cunningham in New South Wales, and labelled “a tall twiggy shrub in elevated swampy lands B. Mountains, W. Port Jackson and Country N. from already suggested by A. e Candolle.

This uncertainty is due entirely to the discrepancies between the description which is too short to stand by itself and the figure which, if Lindley’s very precise statements are worth anything, shows a great lack of accuracy. Lindley insists upon the leaves being terminated by a “blunt callus” (callo obtuso apiculatis) and beg “not merely slightly three-ribbed at the base, but plainly so through their whole length,” while the artist represented them as very acute or even produced into a fine pungent mucro and without any indication of ribs. Then in the description the anthers are sai are written up “ Epacris dubia” ; but the writing is R. Brown’s and much older than Lindley’s description of E. dubia. Possibly it was never intended for a specific name and stood merely for “a dubious species.” : E. heteronema of the Flora Australiensis is therefore a composite species, made up of four distinct elements, none of which can be 17122 A2 216 E. heteronema, Labill., Nov.

Its general habit is that of a small-leaved P. ovata, but in the inflorescence and bracts it resembles P. frutecu- losa. Its perianth is that of P. ericifolia, and the projections at the base of the style may correspond to the more definite ridges at the base of the style in that species, to which it is probably most nearly allied. 1135.

Certain features are identical in the different groups, namel the Danthonia (Gramineae) meadows or moors of the Auckland and Campbell Islands, the Olearia Lyallii (Compositae) formations of the Snares and Ewing Island, and the Pleurophyllum Hookeri (Com- sitae) formation of the subalpine zone of Auckland, Adams, and Campbell Islands. Space does not permit a review of the various formations in detail. The sand dunes, however, are remarkable in having no sand binding plant, Scirpus frondosus, though common in Stewart Island* and the Chatham Islands, being absent. In the Rata forest the conditions are very hygrophitic, and bryophytes abound and have in the long course of ages formed a deep deposit of peat. The forest passes insensibly into mountain scrub. The Pleurophyllums—of which some excellent figures are with Stilbocarpa polaris (Araliaceae) form one of the most striking associations of the islands, and probably represent, according to Cheeseman, the remnant of the ancient endemic flora of this region. f introduced plants in the Auckland group, Phormium tenaz, which is also naturalized in Campbell Island, appears to be making steady increase and invading the young forests. © Dr. Cockayne’s memoir affords highly interesting and instructive reading, and conveys an excellent picture of the conditions of vegetation in the Subantarctic Islands. “Introductory Essay” to the “Flora Antarctica,” to * Stewart Island forms the subject of “The R —— " . eport of a Botanical Surve ee a ne, recently published by the Daparunaat of Lands, New sites ans sions ed 4 Paes of number of excellent pictures of the vegetation, Tslands Hirpedition. interest in connection with the Memoirs of the Southern 259 represent the remains of an ancient flora which managed to survive the glaciation of the island similar to that from which Heard Island is now emerging, and that the remainder of the flora with its Fuegian facies must be regarded as a recent immigrant, which, owing to the direction of the prevailing wind, has come from South America. Pelagic birds are regarded as the main agents in carrying the seeds, and it is pointed out in support of this view that most Kerguelen plants have seeds which permit of such a mode of transport. Certain Fuegian plants are found in New Zealand and the Southern Islands, and several of these also occur in Ker- guelen, This, however, is not taken to indicate the possibility of a former great extension of the Antarctic continent, but rather points to the general circumpolar character of the Antarctic vegetation. In the Southern Islands fifty-three endemic species are found, and some interesting notes are appended to each. Many of these are confined to a single island, which points to the relative antiquity and long isolation of the several islands. Two groups are distin- guishable among the endemic plants—one of an ancient, the other of a more modern character, the latter showing fairly close affinity with New Zealand. Among the ancient types—including some thirty-two species—Pleurophyllum, Stilbocarpa, Ligusticum (Um- belliferae), Celmisia (Ionopsis section) are some of the most charac- teristic, and probably represent the relics of a former wide-spread flora. The more recent plants appear to be of the nature of immi- grants from New Zealand, which have arrived after the separation of the islands. Thirdly, there is a small Fuegian element of recent origin, and not found in New Zealand, probably due to transport by pelagic birds. This includes Ranunculus biternatus, Colobanthus subulatus ( Caryophyllaceae), and Azorella Selago ( Umbelliferae). It is suggested that Cotula plumosa (Compositae), and Veronica elliptica are really New Zealand or Southern Island plants which ave been conveyed thence to Kerguelen and Fuegia i ME and that Sophora tetraptera offers an analagous case as the see may have floated from New Zealand to Chile and Juan Fernandez. Our author then concludes that the flora of the Southern Islands, comparatively recent severe glaciation of the Antarctic region which he, no doubt rightly, holds responsible for the destruction of the ancient antarctic flora of the cireumpolar area, but the remnants of which can still be seen in the remarkable Pringlea and perhaps also in Lyllia and Colobanthus kerguelensis of Kerguelen and in the Stilbocarpa-Pleurophyllum group of the Southern Islands. eS oe ce a a le 260 A medicinal plant from British Columbia—In November, 1907, r. J. F. Davison forwarded to Kew some roots of a plant collected by his father, Colonel Davison, in British Columbia. In the letter which accompanied the specimens, the following informa- tion is given. “I am sending some roots of a plant something between celery and carrot with which the Indians cure a sore throat. They chew a small piece about the size of a pea but do not swallow it .... I got these about 6,000 fect above sea level . . . . neara stream.” Colonel Davison, in a recent letter, informs us that the plant is called by the Indians “ Tiu Piute.” The root is also boiled to make a tea, and used by the Indians for fever. He adds that his guide had a very bad sore throat, and an Indian gave him some of the root to chew, which cured him. The roots were collected high up the mountains above Kootenay Lake, near Mount Hooker, not far from Nelson. Para-Rubber in Assam.—We have been informed by a corre- spondent that Para rubber (//evea brasiliensis) has been success- fully grown on an estate in Assam for the last four years. The Sibsagar District, on the Dekhu River just at the foot of the Naga Hills ; the Naga path passes through it, and there used to be a guard stationed there some 25 years ago. ‘Our manager at Behubar (that is the name of the garden) wrote in March, 1909, ‘My Para rubber trees have got through the cold weather all right, they have nearly all shed their leaves which they are supposed to do when they are about four years old, and have already begun to throw out new shoots. I really think they will do all right from now on ; the stems of some of them are quite 15 inches in girth,’ and in December, 1909, on his return from leave in England, he writes ‘The Para trees are looking very well and have put on a lot of growth this year and thickened out a lot. I am in hope some of them may seed next year. I wish we had more Para rubber and ready for tapping. I had no idea it would have done so well.’ ” It is hoped that specimens from these trees may be received for examination. ROYAL BOTANIC GARDENS, KEW. BULLETIN OF MISCELLANEOUS INFORMATION. No. 8.] : (1910. XXXVII.—A VISIT TO THE ARNOLD ARBORETUM. (With Plates). W. J. Bran. For many years past the most generous contributor of hardy trees and shrubs to Kew has been Professor C. $. Sargent, Director of the Arnold Arboretum, near Boston, U.S.A. It has long been known to us that in the establishment he controls there exists the richest collection in the world of the hardier North-east American and North Asiatic woody plants, and, with a view to ascertaming what was lacking in, and might be obtained for, the Kew collection, I was deputed by the Director to pay a visit to this establishment, and afterwards to see as much of the horticulture—especially the tree and shrub growth—of the surrounding country as was possible in the twenty days I remained there. landed in Boston on June - 16th, and sailed for home from New York on July 6th last. About half my time was spent in the Arnold Arboretum, and I also visited the public gardens of Boston, New York and Rochester, the Victoria Park on the Canadian side of Niagara, as well as some — gardens of repute in the neighbourhood of Boston and New ork. I have to acknowledge my indebtedness to Professor Sargent not only for many courtesies received whilst I stayed in the Arnold Arboretum, but also for using his good offices to make my visits to other establishments easier and more profitable. et History AND ORIGIN. The Arnold Arboretum extends over some 220 acres and is situated in Jamaica Plain, one of the suburbs of Boston, easily reached from any part of the city by electric tramears. It sed its name and origin to Mr. James Arnold, a wealthy merchant of New Bedford and a member of a well-known Quaker family, who, about the year 1870, left 100,000 dollars “for the promotion of agricul- tural or horticultural improvement.” One of the trustees of this fund was Mr. George B. Emerson, the author of the well-known work (17425—6a,) We, 92—498, 1375, 10/10, D&S, 262 on the “ Trees and Shrubs of Massachusetts,” and largely through his efforts and influence, Harvard University was induced to devote 125 acres of some lands belonging to it, known as “ Bussey Farm,” to the purpose of forming an arboretum. Ultimately the fund grew to 150,000 dollars and a chair of arboriculture with Professor Sargent as its first occupant was instituted in 1873. The area has — since been added to by some 90 acres. The income from 150,000 dollars was a small sum with which to make and carry on an arboretum of the dimensions contemplated, yet with this Professor Sargent was expected to develop over 120 acres into a scientific garden and without (as he observes) a mai teak diplomacy and skill of one man. Since its foundation work, Professor Sargent himself has given his books, illustrations and herbarium to the Arboretum—a princely gift, for it forms the bulk of a library now consisting of 23,000 volumes, all of which deal in greater or less degree with the woody vegetation of the globe. The aim of the establishment is to provide facilities for the study of the trees and shrubs of the whole world, but especially those of North America. _A handsome building, known as the Museum, was built in 1892, mainly at the cost of the late Mr. H. H. Hunnewell of Wellesley ; and recently an extension of it has been erected at a cost of £8,000. The older part is now used to hold the library, and to provide offices for the members of the staff. The newer portion houses the herbarium and consists of four storeys fitted with air- ee pose —— to hold 1,000,000 sheets, These steel rom the flo ili accumulation of dust sista dicen aye there is a fine collection which are part of the famous Jesup collection the main portion Bs ea oe in the Batural History Museum a New Pui of c peer —, room there is an excellent collection of the spruces and pj og any of these, especially the cones of firs, - hel pines are too large and bulky to be accommodated on ni ~ e teres ordinary cabinets and are here arranged in drawers.

The last-named is, indeed, the most remarkable part of the grounds. It is a steep hill with outcropping rock and almost precipitous on one side, covered with a primeval growth of “ Hemlock ”’—the American name for T’suga canadensis. Some of the older trees are splendid examples. I measured one over 9 feet in girth of trunk. It is a peculiarly fortunate circum- stance that this wood should have been preserved to a public body © in whose hands its continued existence is assured, for but little of the primeval forest of the New England States remains untouched, and the fact that this tract is almost within the confines of a large city makes it doubly precious. At its northern base a brook finds its exit from the grounds after having traversed them in various phases and makes a charming feature ; especially where it has passed through a flowery meadow, the gully it has worn out fringed wit native vegetation, amongst which, at the time I saw it, the elder- _ berry (Sambucus canadensis) made a pretty display. To the top of the sister prominence, Bussey Hill, a carriage drive has been made, and from this point a great expanse of beautiful country can be seen, especially the rolling outlines of the Blue Hills in the far distance. Another beautiful feature of the Arboretum, and one which makes a special appeal to the foreigner, is the native undergrowth. ‘In place of the lawns and grass which cover so much of the ground in English gardens and parks, there is here a very interesting ground-covering consisting of native plants, amongst which are various species of Vaccinium, Aster, Rubus, golden rod and Asclepias, Baptisia tinctoria, Comptonia asplenifolia and the poison ivy (Rhus Toxicodendron). ery abundant in places—for it has thoroughly naturalised itself{—is the European dyer’s greenweed (Genista tinctoria) making a gay display in early July. Springing up freely every year amongst this low growth is a crop of seedling oaks and hickories so numerous that, in view of the needs of the exotic trees, they have to be mainly treated as weeds. Professor Sargent finds that this low ground-cover is not only more 17425 A 2 264 made and are maintained by the Park department of the city of Boston. (It may here be mentioned that in maintaining these roads, in providing police protection, and in holding the property for ever free of taxes, Boston does something towards the support of the most beautiful of its open spaces). On each side of the The Arboretum is surrounded by a low wall of stone which makes an effective boundary, but is not at present high enough to exclude trespassers—as itis hoped eventually to make it. This wall is covered with a variety of climbing plants, amongst which the species of Clematis, Vitis and Celastrus are most conspicuous. These plants, which are pruned back annually in spring, had, by the time of my visit, about hidden the walls in a beautiful tangle. THE COLLECTIONS. It would, of course, be impossible to give any detailed mention of the collections of trees and shrubs. In a general way they are extremely rich in North-east American and North Asiatic species, but comparatively weak in European and West North American, whilst the floras of New Zealand and South America are scarcely, if at all, represented. the various white.oaks which do not thrive at all with us, and especially the beautiful plumose branching and shapely form of the sugar maple, rarely or never seen in perfection here. The climate of Boston, judging by its vegetation, bears about the same relation to the British Isles as that of Central Europe. The summers are much brigh i In consequence, deciduous trees and shrubs flower with much greater certamty and freedom than they do in Britain, they bear fruit more plentifully, and the colouring of the decaying foliage in autumn is richer than i 1 : The climatic conditions of Boston are evident Sargent from J apan 20 y Jera, and Q., grosseserra abnd vanf o [99% KALMIA LATIFOLIA.

Cercidiphyllum japonicum which at Kew, owing to its young growth being cut back by frost once or twice every spring, has never got beyond the dimensions of a scrubby bush, is in the Arnold Arboretum represented by several vigorous cleanly-grown trees 30 to 40 feet high. The bush honeysuckles (Lonicera) have a value as ornamental fruiting shrubs beyond any- thing we ever experience. By the latter part of my stay in Boston many of them had become covered with crops of fruit beautiful in their abundance and in the translucence of their red, yellow or other colouring. Darwinii, the New Zealand veronicas, the bay laurel, Magnolia grandiflora, the arbutuses are all too tender to be grown in the open. In the matter of evergreens as a whole English gardens have much the advantage. KALMIA LATIFOLIA. : i been shrub, although long introduced and well known, has either neglected in Britain or that our climate generally is ae ne ve adapted for it as it is for most evergreens. It wo ce ae however, that the former is the case as they are some very specimens in the South of England. : : The botanical collection of shrubby plants is arranged in a series of long parallel borders, each border being about 8 or 10 feet efor t 266 herbaceous plants at Kew. Considered as part of the landscape this system is not beautiful, especially in the early stages, when the plants are not fully grown and bare spaces yet await their destined occupants. But for purposes of botanical study no other arrange- ment is so convenient. The collections of trees are, of course, spread over the Arboretum generally, the earlier natural orders (in the Bentham and Hooker sense) being planted at the eastern portion of the grounds near the Museum. A special consideration is paid to American trees that reach timber-producing size. With these the system is to plant and (second) a single specimen at a distance of not less than 100 feet from its companion group. This is to show its value as an isolated tree for gardens, parks, &c. [See Plate.] AMERICAN THORNS. One of Professor Sargent’s great tasks for some years past has been the elucidation of the North American Crataegi. It has involved an enormous labour but during the course of it he and his co-workers have been able to introduce to cultivation many new, very distinct and beautiful species. A number of dwarf bushy — are of particular interest to planters because their low, almost shrubby habit makes them suitable for places where the older thorns, from considerations of space, could not previously be own. out fifteen acres on the eastern slope of Peter’s Hill have been devoted to the type collection of American thorns. The plants have been raised from the type trees of each species and every plant has its place defined on a plan of the site, so that, in case of loss of label, its identity would be recoverable. From ten to twenty years must elapse before this collection reaches its best, but it will eventually constitute probably the most remarkable assemblage of members of a single genus in the world. It was too late in the season to see the flowering of the rich and well-grown collection of garden varieties of lilac, but Syringa japonica, the noblest of the genus and a tree here over 30 feet high, was very striking in the profusion of its large pyramidal panicles of white blossom. Even with us it is a very useful small tree because of its late flowering, but it is one of the instances already alluded to where North Asiatic deciduous trees thrive much better in places where the summers are hotter than ours. One of the great annual displays of blossom in the Arboretum is made by Rhododendron Kaempferii, a Japanese ally of R. indicum but very hardy, introduced by Professor Server less than 20 years ago. ‘This and most of the other azaleas were past before my visit, but I was fortunate to find R. arborescens—an azalea native of the Eastern United States—tfully in flower. Its flowers are white with long red stamens, and its charm is heightened by a most EOE perfume. It is curious that it is scarcely known in British Kew Bulletin, 1910. ULMUS RACEMOSA, [To face page 266. 267 Several notable hybrid roses have appeared in the Arboretum raised by Mr. Jackson Dawson. Mr. Dawson has, like Professor Sargent, seen, and helped in, the development of the Arboretum since its inception, and in regard to the outdoor department he has in a great measure played the part of builder to that of the Professor’s architect. Trees now 60 feet high, he himself raised from seed, or collected as seedlings in the forests. Gifted with that peculiar understanding of plant life which enables its possessor to ivine by intuition the treatment best suited to his charges and the happiest devices for increasing their number, Mr. Dawson has done much by his genius as a propagator towards making the collections so rich as they now are. e was about the first to recognise the value of Rosa multiflora and R. Wichuraiana for hybridising, and such fine roses as The Dawson, Lady Duncan, E. C. Egan and Arnoldii are the products of his skill. I was fortunate to see a new rose in flower which Mr. Dawson has raised and called “ Professor C. 8. Sargent.” The original plant raised in 1903 is now 8 feet high and 9 feet through, a sturdy bush with splendidly vigorous foliage. It bears large flattish trusses of semi-double flowers 3 inches across, of a delicate, apple-blossom shade, and from 30 to 50 ina truss. In June it was carrying thousands of flowers—a wonderfully beautiful picture. Its parentage is as follows: pollen bearer “ Baroness Rothschild” ; seed-bearer an unnamed hybrid between R. WichuraianaP and “ Crimson Rambler”. In this interesting combination the influence of R. Wichuraiana is only seen in the very glossy, thick, dark green foliage. : Wuat THE ARBORETUM HAS DONE. 0 one respect part of the park system of Boston, it provides a very beautiful place of resort for the people of that city. It provides also many lessons in landscape art, for there is evidence that every aspect of the grounds has been the subject of careful study in that respect. While the scientific side of the establishment necessarily dominates all others, the natural beauties of the site have not only been preserved but greatly enhanced. Considered from the practical side, as apart from pure botany, perhaps the most notable work it has done has been the popularisa- tion and dissemination of American trees and shrubs. Before its foundation, American gardens appear to have mainly depended for their ornamentation on plants of European origin. As an instance, I was told that 30 to 40 years ago one could not have purchased one hundred American oaks in American nurseries. the East United States has given an extraordinary number of beautiful trees and shrubs to English gardens, and in the latter half of the 18th century and the beginning of the 19th their introduction and cultivation was the chief interest of the most ardent horticul- turists of the period. Many of the shrubs then introduced dis- appeared in course of time, and the Arnold Arboretum has done 268 much good work in re-introducing them. Such shrubs as Vaccinzum hirsutum, Rhododendron arborescens, Gaylussacia brachycera, Kalmia cuneata and Fothergilla major, are a sample of the many delightful plants which have in this way been restored to us. Many quite new species have also been introduced to cultivation, whilst others, long known but rare, have been made more plentiful.

XXXVIII—NEW IMPATIENS FROM CHINA. J. D. Hooker. In April of the present year Prof. C. S. Sargent, Director of the Arnold Arboretum, Boston, U.S.A., placed in my hands for exam- ination and subsequent transference to the Herbarium of the Royal Botanic Gardens, Kew, ten species of Impatiens found by the cele- brated traveller and collector Mr. E. H. Wilson in China, during is second botanical mission to that country in 1908. Of these the following six are new to me, raising the number of Chinese species 270 of which I have MSS. or published descriptions to upwards of one hundred and seventy. Clavis specierum novarum.
