ORCHIDS. AliKVlEW of the OrthicJs during the past yt'iir discloses ithe fact that hybrids have been pre-eminent in 1916, there having been very few novelties amongst species and varieties of specits. The only new- species of importance was the New Guinea Uer.drobium Wollastonii, which flowered in the gardefls of the Hon. N. Clias. Rothschild -at A.shton Wold, Ounpa, DC, Prodr.,\-., 272; Eurybia Gunniana, DC., Prodr., v., 268; Hook, f., Fl. Tasm., i., 175; E. subrepanda, DC., I.e." Following the geographical distribution of the species, " Queensland, N.S. Wales, Victoria, and Tasmania," there are descriptions of three varie- ties with their synonymy as follows: — (1) " var. canescens ; (2) var. lirata— Aster liratus, Sims, Bot. Mag., t. 1509; Diplo.-^tephiuni lyratum, Nees, Gen. et Sp. Aster, 188; Eurybia lirata, DC, Prodr., v., 267; Hook, f., Fl. Tasm., i., 175, t. 43; and (3) var. quercifolia^Aster querci- " See Jnurn. of Board nf Agric, XXIII., 9. folia, DC, Prodr. v., 272; Eurybia rugosa, F. Muell, ex Archer in Journ. Linn. Soc., v., 22." From the above somewhat formidable array of synonymy it will be seen that the specific name stelluialus was first used by Labillardiere, and is the original of De Candolle's Olearia stellulata. Labillardiere gives an ample description and an excellent figure of his plant, a specimen of which is preserved in the Natural History Museum, South Kensington. A photograph of the illus- tration is reproduced In fig. 1, with the per- mission of the Director of the Royal Botanic Gardens, Kew, and a drawing of a typical leaf is shown in diagram (see fig. 3 (1). It is a v.-ry different species from Olearia Gunniana. Hook f., of which a photograph of a typical ^ecimen (dried) is here given, and a drawing of a typical leaf (see fig. 3 (8). There are numerous specimens of 0. steUulata in the Kew Herbarium, but no cultivated ones, and it seems certain that this species is not, and never has been, in cultivation in this country. The next synonym quoted by Bentham is Eurybia fulvida, Cass.," but as this was merely a new name pro- posed' by Cassini, with no apparent reason, for Aster stellulatus, Labill., it may be passed with- out further comment. As may be noted, Cas- sini's name was also used by Sir Joseph Hooker in his Flora of Tasmania, where the species were much more critically dealt with than in the Flora Auslraliensis. Diplostephium stellulatuni, Nees, is only LabiUardiere's plant under a different generic name. Aster plilogopappus, Labill., is again well-described and figured by Labillardiere, and is, I consider, a form of Olearia Gunniana, Hook. f. Sprengel preferred the name A. phlogotrichus, which accounts for the next synonym. Eurybia quercifolia, Cass., is a new name for Aster phlogopappus, Labill., another alteration of name for no apparent reason. Diplostephium phlogotrichum, Nees, and Olearia phlogop.ippa are merely other combinations for the respective species mentioned above. Then we have Eurybia Gunniana, DC, the description of which was founded on plant* collected by Cunn and forwarded by Lindley to De CandoUe. And the last name quoted by Bentham is Eurybia subrepanda, DC, another species described in De Candolle's Prodromus. In the above synonymy of 0. steUulata, as de- fined by Bentham, the writer considers that there are at least three distinct species of Ql^aria represented, O. steUulata, DC, 0. Gunniana, Hook f. {Hot. Mar/., t. 4638), and O. subrepanda, Hutchinson (comb, nov.) ; whilst under the varie- ties there are perhaps four others, 0. canescens, Hutchinson (n. sp.), 0. lyrata, Hutchinson (n. comb.), O. quercifolia, DC (non Cass.), and O. rugosa, Hutchinson (comb. nov.). O. canescens, O. quercifolia, and 0. rugosa are very distinct species indeed ; the last two have separate geographical distribution, 0. quercifolia being confined to New South Wales and 0. rugosa to Victoria. In order to establish the identity of the typical form of O. Ounniiina, it was necessary to consult the Lindley Herbarium, and the writer is much indebted to Prof. Seward for the loan to Kew of the necessary type specimens from Cambridge. In the Lindley Herbarium, as at Kew, there are several different forme labeUed 0. Gunniana, but it is comparatively easy to fix upon the one de- scribe- temperatures should range l.etween 45° and 50°. allowing the heat to drop to about 40° on cold nights. A high temperature for Cinerarias is harmful, and tends to encourage the spread of green flv and other insects. Fumigate the frame as often as necessary to keep the plants clean. T.at« batches of Cinerarias in frames can be kept cooler, admitting air daily in suitable weather. Herbaceous Calceolarias.- These sbowy plants succeed under conditions similar to those given to Cinerarias. Two important points are : never to allow the plants to suffer a check through becoming pot-bound in their early stages, and to avoid high temperatures. Shift the plants into larger iwts as they requii-e it, using a rich open .soil. Sta.nd tte plants, if possible, on a damp bottom. Cleansing Plant Houses- AU plant houses should be thoroughly overhauled and cleaned during the winter months. Wash all glass and woodwork, both inside and out, limewash all ualls under M-ages, and do any necessary repairs. Wash the fine gravel, or renew the material nscl on the stages, and see that all plants are clean before being brought in. THE FLOWER GARDEN. Bv W. J. GrisE, G.irdener t.> Mis. Dempster. Keele Hall, St.iflord.shire. ISHRUBBERiES.-The unfavourable weather has greatly delayed all work in the flower garden. Where the .soil is very wet planting should be discontinued for a time, but evcrj' opportunity should be taken directly it is in a suitable con- dition to complete th*" work of planting deciduous trees and shrubs. The plants in the s h rubbery should be trimmed and r e g u la t e d , using the knife freely on the com- moner ever- greens, especi- ally where they are en. croaching on choicer plants. A light fork- ing of the soil in necessary directly the planting is fi'iiisihed, incorporating fallen leaves with the soil as the work proceeds. Vacant spaces in the back of shrubberies may be filled with surplus herba- ceous plants. For these the ground sliould be trenched and liberally manured, removing old tree roots or r.tunn>s. Where Howers are grown in the foreground of shrubberies, the roots of the shrubs and trees quickly imipoveriish the soil, wh/ioh should be trenched every year, en- riched with an abund.ance of manure, leaf-mould or old potting soil, and the opportunity taken to restrict the roots of the trees and shrubs. All rubbish collected should be burned and the ash distributed over the border. DiOGiNG Flower Beds.— It i^ not advis- able to bring very heavy, retentive soil to the surfacx*, esipeciajly whei'e annuals are to be sown. In such cases take out a trench 12 inches d-ep and 3 feet wide. The bottom of the trench should be well broken up to a similar depth, mixing with it a quantity of sand, ashes, leaf- mould or decayed vegetable refuse. Next year the soil may be trenched 2 feet deep. The sur- face should be left as rough as possible until planting time. Seeds.— Home-saved seeds and any that re- main from last season should be tested to ascer- tain their germinating qualities. Simplify the bedding schemes as much as possible, and use Antirrhinums, Larkspurs, Lupins, Lavateras, Godetias, Clarkias and Statices freely instead of the usual tender plants. THE KITCHEN GARDEN. By J. DrNN. Foreman, Royal Cirdens. Windsor. Early Peas. -A sowing of some liaa-dy variety of Pea may be made as soon as the soil is suifioieintly dry, "on a warm south bordeo- wliich has been trenched ajid ma.nuaied dn early wlinlter. Sow tie seeds in shaiUow trenohes, cover wirtili 2 inches of fine soil, and keep a careful watch for mice and other pests. Ohielsea, Gem is a good dwarf variety for eaa"ly sowing, and The Pilot is one of the best early 3-feet Peas. Early Car- rots IN Pits.— — A sowing cf Carrot's should be made with as little delay as possible, on a gentle hotbed ^_^ _ made up in a brick jnlt ; the hotbed may be composed entirely of leaves, which should be trodden lightly together so that they may prtfuuice a mild and lasting warmth in the soil. Spiread the soil over the bed to tihe depth of 8 inclies. When it has become suf- ficiently warm and dry it sihould be made moderately firm with a wood rake. Sow the seeds carefully and cover lightly with fine soil. The surface of the bed should l>e lightly damped on fine days and the pit kept dosed luitiil the young plants appear thrxnigh the surface, after "which ventilation should be carefully given to keep tihem from becoming drsiwn. Lettuces.- A sowing of Lettuce seed should be made at once in boxes or pans, which may be placed in gentle heat until germin.ation takes place. When the plants are well through the surface they may be removed to cooler' quarters within a few inches of the glass and gradually hardened, so that they may be planted in cool pits as soon as large enough to handle. Golden Ball, Tom Thumb and May King ame good varieties. Broad Beans.— The Bean reqmTies a good rich soil, and may be sown as soon as the ground is in suitable condition in a sheltered spot; sow- in drills 3 feet apart and 3 inches deep. Broad Windsor and Bock's Dwarf Gem are suitable. Cauliflowers.— Plants raised in September should be freely ventilated during mihl weather, and watered as often as necessa.l-J^ On sunny days the lights shou'd be reiiiovolants for fruit- ing in May. Sow the seeds thinly i!n piuis of sifted soil "and plaoe in a temiierature of 70°. As soon as the seedlings are large enough to handle they must be oa.refullv potted into thumb- pots and i)lace. tts Wood, Godiilming, Surrey. Planting Operations,— The weather has not been congenial for fruit tree planting re- cently, but with open weather any arrears can be got on vjith as soon as possible — especially so on light soil. The soil in this jiarticular dis- trict is very light in texture, and after rain or frost has cleared for a f e w hours the ground can be easily worked. Any trees that have recently arrived from the nursery or other sources should be well covered w ith some fiost - proof material, or laid in a trench and covered with soil. During inclement weather there are m a n y things that can be done, such as preparing stakes, (labels, and soils for [Tdanting. The mixing of sous cannot be done too thorouglliJy, espeoiaily those which contain manures. Draining opera- tions can be pushed along, even in frosty weather. In heavy soils draining is requisite for the moi-e_ tender fruits, such as Peaches, Nectarines, Apri- cots and Cherries. The drainage may consist of a good supiily of rubble under each tree, or by putting in 2iin. drain pipes; but if the land is drained the former plan is as practical as it is simple and effectual. Many young fruit trees have been ruined through being planted in sour, waterloggetl soil. Propagating.- It is not too late to put in cuttings of Gooseberries and Currants, and it is always as well to have a small stock of these in or'der to fill gaps, or make new plantations, or to give away to the employees on the estate. Select straight shoots, or pruiiings, and rub awav the basal eyes, or buds, and insert the cut- tings about 6 inches apart in a trench chopped out about 6 to 8 inches deep. If a little lime rubble is at hand, a sprinkling after it has been passed through a i inch sieve can with advan- tage be sown along the bottom of the trenches. Be careful to propagate from clean and healthy bushes, and select only such varieties as do con- sistently well in the particular locality. Tread the cuttings in very firmly. The firmer they can be made the better will be the results. Orchard Trees.- Orchards containing old trees can be attended to as opportunity occurs. Though it is difficailt to obtain much labour this seiison, some of the old, weH-pract^'sed hands are fltill available, and w.ith proper supeiin^ision are cajpable of good and useful work. The trees oan be thinned and the oeaitres opened up, wfliich. makes Apple and Pear giatheiring easier and quicker. Cut out all thmn and weak wood; aijn at taking all oi-osa or crooked growth away, and all dead or decaying wood. If there is rnucHi dead wood the trees should be grubbed, and more profitable trees planted. Varieties which are not gootl or marketable should be headed back for grafting with good varieties In due season. This system is one which should commend itself to every grower, small or large, especially if the tree be vigorous and healthy. Prepare washes for fruit trees that require it," and on fine, still days, distribute them with a fine sprayer. THE GARDENERS' CHRONICLE. [January 6, 1917. EDITORIAL NOTICE.

Like many other horticultural advances, we owe the recognition of these glands to an amateur, M. Desprez, a judge at AlenQon, whose appointment in 1810 as deputy of the Corps Legislatif brought him to Paris, The gardens of the Luxembourg were then a large nursery ; and it was here that M, Desprez spent his spare moments studying the large collection of fruit trees, and here that hg made his interesting discovery. It is remarkable that in the accurate and minute descriptions of fruits wliiich liad been mad© by previous Prencb authors, no menton is found of these st.ructures; but, once pointed out, their diagnostic value was recognised, and soon liecame the basis of all classifications of Peaches and Nectarines. As is well known to most gardeners, the glands are of two types, round and kidney shaped, and a re- markable correlation exists between the presence of glands and the detailed structure of the leaf. Glandless leaves always have serrat<>. margins, while those with glands have orenate margins. The first paper of importance calling at- tention to these structures in this country was that of John Robertson on " The Clas- sification of Peaches and Nectarines," pub- lished in the T ransactions of the Royal Horticultural Society. Lindley, in a later paper in the same publication, made the gland.s or their absence the basis of a classification. In 1867 E. A, Carriere published a new system of classification, in which he pointed out the presence of inter- mediate types which are now generally re- cognised as " round to kidney shaped." The study of these characters had so far been entirely limited to their value as identification marks, and no careful study had been made as to their physiological characters and development. This, how- ever, has now l>een rectified bv a recent paper by Mr, C, T, Gregory.* in which pomologists and botanists alike will find points of interest. As in most detailed studies of this nature, we find that the rough distinction between " kidney " and " round " loses its desirable sharpness under close investigation. In the draw- ings of types which the author gives there are many that would puzzle an expert to class either in one division or the other, and it would seem possible to establish several clear types both of " kidney " and " round." It is interesting to note that in the large number of varieties examined no serrated- leaved forms were found with glands, thus confirming previous observations. On the physiological side the author shows that the glands are modified leaf-.spine,s, and after the secretory process is fini.shed the upper part of the gland gradually dis- integrates with the production of a corky layer which slowly extends downwards, so that in some oases it becomes entirely de- composed. Peaches and Nectarines offer a fa,scinat- ing problem to the student of genetics. The presence and absence of the glands', the large .and small flowers, the reported susceptibility of the glanded varieties to Peach leaf blister and the glandless to mil- Jew, present material for study of the gre.atest possible interest. Our AuMANAC.-rhe next issue of the Gar- dcncrx' Chronicle will include a sheet almanac for 1917 containing particulars of liorticultural appointments up to the time of printing. Fo*o Production in Scotland.— The Marquis of Breadalbane, in a letter to the Scotsman, has described the success of his ex- periments in vegetable culture in hie gardens at Taymoutii Castle, which had been left almost without men in response to the calls to the Colmu-s. By means ot a Cana.dian plougih; — the Cocks.liut — the land was double plouglhed, with hig'hly satisfaotory iiesults, i'he Ciity of Edinburgh is taking up the quesltdon of allotmemts with great vigouir, and an effort is be-ing made to cultivate as mudh * The Taxonomic Value and Structure of Ptach Lea/ Gland), C.

M'Hattie, the City Gardener, has given addresses on the subject of allotments and vegetable growing. In Dund,?e the matter has also been under consideration, and a pro- posal to crop a large extent of land is likely to be adopted. Ministry of Food Appointment.- Captain Charles Bathhrst, M.P., has, on becoming Parliamentary Secretary to the Ministry of Food, relinquished the post of Organiser of the Land Settlement Scheme for Ex-Service Men, which he has held under the Board of Agricul- ture and Fisheries in an honorary capacity for the last eight months. The duties have been taken over by Sir Richard Winfrey. M.P., Par- liamentary Secretary to the Board of Agriculture and Fisheries. The Gardeners' Royal Benevolent In- stitution.—The voting papers for the election of pensioners to this institution have just been issued. There are sixty-four candidates, and it is proposed to elect eighteen. The dif- ference in these figures shows the increased amount of support required to enable the insti- tution to relieve the necessitous cases that con- stantly arise amongst gardeners and gardeners' widows, for, it may be pointed out, the cases included in the list have all engaged the atten- tion of the Committee, and each is recommended equally to the sympathies of the electors. The official notice of the meeting is iis follows : The seventy-seventh annual general meeting of the members and subscribers of this Institution will be held at "Simpson's," 101, Strand, London, on Tuesday, Jpnuary 23, 1917, at 2.45 p.m., for the purpose of receiving the report of the Committee and the accounts of the Institution (as audited) for the y?ar 1916, electing officers for the year 1917, and for the election of eighteen annuitants on the funds. The chair will be taken by Sir Harry J. Veitch, treasurer and chairman of committee, at 2.45 o'clock. The poll will be open at 3 o'clock and close at 4 o'clock precisely, after which hour no voting papers can be received. The Late Mr. N. N. Sherwood.— The gross value of the estate of the late Mr, N. N. Sher- wood, of the firm of Hurst and Sons, Hounds- ditch, and Prested Hall, Kelvedon, Essex, has been returned at £514,949. Deceased left sums of £500 ea,ch to the Gardeners' Eoyal Benevolent Institution and the Royal Gardeners' Orphan Fund, Bequest.— Mr. William Heseltine Mudford, formerly Editor and manager of the Standard, who died in August last, left to his gardener a sum of £1,500, and his guns, telescopes, etc. Acorns and Chestnuts from Verdun.— It will be remembered that Lord French, when at Verdun, gathered from the battlefields Sweet Chestnuts for planting in his garden, to foi-m au avenue as a souvenir of the glorious city. Others having expressed a wish to obtain, seeds for the same purpose, ithe Deputy-Mayor of Verdun has forwarded a consignment of both Chestnuts and Acorns to the London and North- Western Railway Company, and the seeds will be sold in aid of the War Seal Foundation (L. and N.W,R. Section), which aims at providing cJieery homes for L. and N.W.R. servants who may be totally disabled in the war. Manganese as a Fertiliser.— The diver- gence of opinion with respect to the value of manganese salts in effecting increased crop pro- duction appears to be explained by the results of recent experinii^nts* by Messrs. Skinner and Reid. These authors find that whereas man- ganese, applied as manganese sulphate at the rate of 50 lb. per acre, is without beneficial * The Action of Manganese under Acid and Neutral Soil Conditions.

Wheat, Rye, Beans, Maize and Cow Peas all give higher yields when the soil rendered alkaline by lime was treated with manganese sulphate. A Device for Sending Pollen by Post.— In the course of a valuable account of his work in breeding the Sugar Cane in Madras Dr. B.\REER, Government Sugar Cane Expert, men- tions that a successful way of sending pollen by post is to enclose it in small gelatine capsules. This method, which we do not remember to have seen described before, should br? useful to plant-breeders generally. Morocco.- yAe Board of Trade Journal states that H.M. Agent and Consul-General at Tangier (Mr. H. E. White, C.M.G.) reports, under date November 27, that the Resident- General of the French Zone of Morocco has issued an Order appointing a Commission to study the question of colonisation and to suggest the best means of encouraging the settlement of colonists who will develop the agricultural riches of that region. It appears from the local press that steps are being taken by the Director- General of Agriculture for the grant of Magh- zen {i.e. State) land in small lots for the purpose of market gardening and in larger tracts for general agricultural purposes. An agricultural irrigation service has been formed for the pur- pose of scheduling the hydraulic resources of the country and at the same time of aiding colonists with technical advice on the irrigation of their lands. Agricultural Appointments. -The Right Hon. R. E. Prothero, M.P., President of the Board of Agriculture and P'isheries, has ap- pointed Mr. A. W. Monro to be his Private Secretary, and Mr. A. Balfoue to be his Assis- tant Private Secretary (unpaid). The "Gardeners' Magazine."— We deeply regret to learn from a note published in the last issue of th(^ Gardener.^' Magazine that this journal has decided to su.spend publication dnring the period of the war. Calyx -splitting in Carnations.— The careful work carried out at the New Jersey Ex- periment Station* does not add very materially to our knowledge of the causes which bring about the splitting of the calyx in Carnations. Numer- ous countings of normal and split Pink Enchant resfi show that whereas the former has an average of sixty-four petals, in the latter the number of petals ranges from 70 to 168, averag- ing about 84. Periods of dull, sunless weather increase the amount of splitting in flowers opening about a month after those periods, and hence it is to be inferred that lack of light dnring bud formation is one of the causes of splitting. The constitution of the plant also counts — for manifestly a flower which produces a mass of petals too great for the capacity of the calyx is bound to split. This is well shown when White Perfection and Matchlejis are compared. The former has a slender calyx and a relatively large number of petals ; in the latter the calyx is large in relation to the number of petals which it contains. Perfection often splits, whereas of Matchless grown at the New Jersey Experiment Station only 5 per cent, .splits. Gassing the "Prickly Pear" in Queens- land. - Opuntias, or "Prickly Pears," as they are popularly called, are a great pest to gi'owers in Queensb.ud, and various meithods have been adopted to destroy the plants. After many months' experiments, the Itffcaitment of certaiin .species of OpuntiaiS with ar.senic trichloride in a gaseous form has been proved to be effectiive, while tJlie pro- blem of manufacturing the trichloride in large quantities has also been successfully overcome. • See FlorintB' Exchange, December 2, 191G. Trichloride is now obtainable in large quantities at a cost of £22 per ton. The place selected in Queensland for the experimental work was Delacca. This district contained some of the worst " Pear " growth in Queensland, ranging from 7 feet to 8 feet high, and of such a dense, impenetrable nature as t-o make spraying im- possible. Areas that had been gassed some twelve months ago are entirely free from the pest. The gas is applied by means of an atomiser. Gassing is done w-ith the best results after heavy dews or rainfall. The trichloride apparently has no effect upon other vegetation, because of their lower water contents, neither is tihere any da.nger in regard to stock. Farmyard Manure.— Dr. Rcssell estimates* that the amount of farmyard manure used The Hall of the National Horticultural Society of France in the Rue de Crenelle, Paris, is a common meeting-place of gardeners and nur- serymen on leave from the Front. We learn that M. GusT.iVE Clement was there a few days ago, probably on the usual leave to celebrate his being decorated, as announced in our issue of the 23rd ult. The current number of I'Horticultvre Fran(;ttise, just to hand, contains the eighth list of honours, in which the names of Frendh liortii- culturisits who have fallen on the field of battle appear. Fifteen names are given, but they are practically unknown to English readei-s. The list of citations from Army Orders is headed by the name of Captain Baltet. In addition to previous honours, Captain Baltet has now received from wJ^^ Fig. 2. — olearta gunntana, type : from a dried sfecimen. (Soe p. 3.) annually in this country is 37 million tons, which, at 5s. a load, represents a yearly value of 9i million pounds sterling. The value of artificial manures used annually is considerably less than this sum, probably not more than 5^ million pounds -sterling. War Items.- We regret to learn that M. Georc.es Truffaut, of Versailles, is home on sick leave. He has many friends in England who will join us in expressing the hope that he may speedily be restored to health. • Lieut. Henri Nonin is undergoing treat- ment for hia shattered right arm at the Hospital of the Grand Palais. Meantime, he is engaged a.s interpreter .at the Statistical branch of the Labour Bureau.

Tests • Agiit. News, Imp. Dept. of Agiic., West ludies, XV. TBE GARDENERS' CHRONICLE. [January 6, 1917. carried out at the Agricultural Experiment Sta- tion, Minnesota, show that germination is better if a sunlight germinator is used. For some species light is esseiitiiil. Furthermore, a change of temperature from 20° C. to 30° C. (20° C. for 18 hours and 30° C. for six hours) gives better results than are obtained by ex- posure of the seeds to a constant temperature of 20° C. Destruction of Fly Larvae in Horse Manure.* — Messrs. Cook and Hutchinson have continued their investigations on the destruction of Ay larvae — previously reported in thesi? pages — and conclude that fly larvae may be destroyed by treating the manure heap with two-thirds of a pound of borax in 10 gallons of water. This amount suffices for 8 bushels of manure. Inas- much as large quantities of borax have an ad- verse effect on plant growth, they recommend, where the manure is to be applied to the land, that powdered Hellebore be used instead of borax. For 8 bushels of manure half a pound of Hellebore mixed with 10 gallons of water makes an effective larvicide. Experiments made witih a mixture of calcium cj-anamid, acid phosphate and kainit — all of which substances have, of course, value as fertilisers — indicate that the larvae may also be destroyed by these substances. A Letter on Land Tillage Published Seventy Years Ago.— A wealthy old farmer, who had for some time declined in health, per- ceiving that he had not many days to live, called his sons to his bedside. " My dear children," said the dying man, " I leave it with you as my last injunction not to part with the famn, whiclh lias now be«n in our family these three hundred years. For t
