ANDREW Murray, Esq., F.L.S., in the Chair. Mr. Webb, of Reigate, sent a Cyclamen which had thrown up a stem bearing leaves and axillary flowers; he had six or eight other plants in the same condition. The stem was round in its lower part, but somewhat aborted in the upper, with a petiole and pedunele partly adnate to it, giving the whole a slightly fasciated appearance. Major Clarke said that he had heard from the late Donald Beaton that cuttings from these stems, which oceasionally occurred, afforded a means of propagating Cyclamens. Dr. Welwitsch had several times met with wild plants of Cyclamen in Carinthia producing similar branches. The grub of a small Moth, probably Zhecla Lsocratis, was shown feeding on the fruit of the Pomegranate. Prof. Thiselton Dyer had seen specimens of Polyporus Pee Ss from Hampstead, riddled in every direction by the larvee of a small Moth. Dr. Welwitsch stated that, from a communication from Count Salms, he learnt that there was now evidence in the Berlin Museum that the parasite producing the deformity exhibited at the Committee on Noy. 1., and of which a similar instance was figured in the ‘‘ Gardener’s Chronicle,” 1871, p. 1425, wasa true Loranthus, as leaves still remained on the specimen. GENERAL MEETING. James Bateman, Esq., F.R.S., in the Chair. Professor Thiselton Dyer commented on the plants examined by the Floral Committee, and especially on Amherstva nobilis, which was originally introduced by Mr. Gibson. Mr. Bateman stated that at Penllagere, near Swansea, Mr. Dillwyn had a plant of Evergreen Beech (agus betuloides), near the tide line, which was 15 feet high, with a girth of 11 inches at 3 feet from the ground, when last measured, near which Arundinaria falcata has attained a height of EXTRACTS FROM PROCEEDINGS.

Benary sent a small variety of Indian Corn, the cobs being from 3 to 4 inches long. SCIENTIFIC COMMITTEE. AnpREW Murray, Hsq., F.L.S., in the Chair. The Secretary brought a branch of a Portugal Laurel in which the leaves were a good deal bleached, while others had only the perforations which are commonly the consequence of frost. The tree had been unhealthy ever since the winter of 1866, and its condition was apparently attributable to that severe season. He also brought a branch of an Apple-tree in which eanker had arisen from the development of adventitious roots. A letter was read from Mr. Thwaites respecting the disease which has affected the Coffee plantations in Ceylon, which is due to a very curious Fungus (HHemuileva vastatrixz) intermediate between Uredinet and Mucedines. It attacks the leaves, and causes them to fall prematurely. A discussion then took place respecting the ‘‘ Australian Caoutchouc,” which has been found on the surface of sandy erounds near Adelaide. It is believed to have been derived from petroleum springs. It is remarkable that it contains traces of the necklace-like bodies which are characteristic of the genus Collema and also Cymbelle. (See for a detailed account Journ. of Bot. 1872, pp. 103—106, and 338.) Prof. Thiselton Dyer exhibited a solution of esculetin which is remarkably fluorescent. He also read an abstract of a paper by C. J. Maximowicz on the ‘‘ Influence of Foreign Pollen on the Form of the Fruit pro- duced.” (See Journ. R. Hort. Soc. n.s. iii., pp. 161—168.) - GENERAL MEETING. Lord H. Gorpon Lennox, M.P., in the Chair. ' Mr. Berkeley stated that the Toxicophlea, which was so much admired by the Floral Committee, belongs to the same natural EXTRACTS FROM PROCEEDINGS, Vil order as the common Periwinkle, and that the bark is used by the Hottentots as an ordeal. Whatever may be thought of the Imantophyllum, it is certainly an improvement on the common form. Mr. Wilson Saunders had also sent flowers of the ornamental Composite Séiftia chrysanths. Horticulturists are much in- debted to Messrs. Backhouse and Mr. Ware for calling attention to hardy spring flowers. Mr. Berkeley stated that plants of Brocoli lifted to protect them from the frost had in many cases rotted off from the middle of the stem. Mr. Bateman commented on the Orchids. Marcu 20, 1872.

Eyre, Esq., took the First Prize for Apples, Mr. Miles and Mr. Parsons also obtaining Prizes. Mr. Ross was the only ex- hibitor for Snow’s Winter White Brocoli. SCIENTIFIC COMMITTEE. The Secretary brought a portion of a small branch of a Cedar the upper end of which had perished, though much larger in dia- meter than the part beneath it which had been injured by the frost of 1866 ; it illustrated the fact that the injury induced by frost is frequently not fully apparent till after the lapse of some years. A plant of Jresine Herbst was sent from the Society’s garden at Chiswick, in which half of the whole plant was green while the other half was red. Prof. Thiselton Dyer pointed out that the bright pink bracts of Dalechampia Roezliana acquire a green colour as the fruit is developed. GENERAL MEETING. J. Bateman, Esq., F.RS., in the Chair. Attention was again called to TZoxicophleaa, which scarcely differs from Carissa, and to the curious Azalea linearis sent by Messrs. Standish. Prof. Thiselton Dyer then commented on General Pleasonton’s theory respecting the effect of coloured glass on the growth of Vines. Violet light was anything but advantageous for two of the things which were most essential to the growth of plants—the formation of chlorophyl and the evolution of oxygen from the leaves. Hecould not, therefore, encourage the adoption of this system. Mr. Bateman then observed that care should be taken in staging Orchids that their tints were not over- whelmed by the primary colours of Hyacinths and Tulips. THE JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY OF LONDON. I. On the Production of Honey-Dew. Translated in Abstract from a Memoir by M. Boussingault (Comptes Rendus, Jan. 8, 1872), by W. T. Tuisetron Dyer, B.A., B.Sc., F.L.S. [Read April 3, 1872.] On July 21, 1869, at Liebfrauenberg, the leaves of a Lime were coated on their upper surface with an extremely saccharine viscid matter. The tree, in fact, afforded an example of the production of honey-dew, a manna-like substance, which is frequently observable upon the Lime, the Black Alder, the Maple, and the Rose. I have myself noticed it upon a Plum-tree, and—which is a very rare occurrence—upon a young Oak.* On the 22nd the honey-dew was sufficiently abundant in the morning to fall in large drops upon the ground. It was a shower of manna. At three o’clock the saccharine matter no longer remained fluid upon the leaves which were exposed to the sun. It had sufficient consistency not to adhere to the fingers when touched ; * [A saccharine substance exudes from the leaves of Quercus mannifera in Kurdistan. (Lindley, Bot. Reg., May and June, 1840.) Such a secretion from the Oak is more than once alluded to by Latin poets. In the Golden Age—“ dura ‘quercus sudabunt vescida mella.” (Virg. Ec. iv., 30.) Martin remarks (Virg. ii., 36)—“ It is no uncommon thing to find a sweet glutinous liquor on Oak leaves.” —W, T. D.] | VOL, Iv. B 2 ROYAL HORTICULTURAL SOCIETY. it formed, in fact, a sort of transparent and flexible varnish. Out of the sun the honey-dew still retained its viscous condition. On the 23rd, at seven in the evening, several leaves at the ex- tremity of a branch were washed and sponged, so as to remove all the saccharine matter. At six o’clock the following morning the leaves which had been washed seemed free from honey-dew, but, on examination with a lens, minute glistening dots, due to very small drops, were observable. At seven the same evening the appearance of the leaves remained the same. The day had been warm ; the temperature in the shade 84°. On the 25th numerous spots of honey-dew were scattered over the leaves, but there were none upon the principal veins; at three - o'clock the temperature was 86°. During the night a violent shower removed a great part of the honey-dew formed during the evening. It became, therefore, impossible to follow, as had been proposed, the progress of the secretion upon the leaves washed upon the 22nd. A swarm of bees settled upon the tree. On the 27th the whole of the honey-dew had disappeared, in consequence of the rain which fell during the evening of the 26th. The temperature had stood at between 62° and 75° F. On the morning of the 28th the leaves bore numerous spots of honey-dew, which had made their appearance during the night. On the 29th it had increased ; on some of the leaves it occupied a third of the surface. At two o’clock the temperature was 84°. On the 30th the honey-dew was very abundant. The Lime-tree remained covered with it till the commencement of persistent rains, which took place at the beginning of September. On two occasions, namely, July 22 and August 1, honayleg was collected by washing the leaves. The solution, after treatment with lead subacetate to precipitate albuminous and mucilaginous matters, yielded a syrup in which crystals of sugar formed. On examination it contained a sugar analogous to cane-sugar, and also a reducing sugar. By fermentation with yeast the two sugars disappeared completely. In the fermented liquid, however, a substance remained possessed of very strong powers of right-handed rotation. This proved to be dextrine, already announced by Berthelot as existing in the mannas of Sinai and Kurdistan, and subsequently by Buignet in a manna occurring in “tears” (manne. en larmes). I have endeavoured to find mannite, and with especial care, because Langlois, an experienced observer, has found it in a BOUSSINGAULT ON HONEY-DEW. 8 saccharine matter collected from the leaves of a Lime. Mannite is so easy to detect that I have not the slightest doubt as to its presence in the product studied by Langlois. Optical observations have shown that the reducing sugar detected in Lime-tree manna is not glucose (Grape sugar), of which the rotatory power is 56° in the right-handed direction, but levulose (inverted or fruit sugar), which has a left-handed rotatory power of 26.° Taking into consideration those substances only which rotate the polarised ray, the composition of honey-dew will be :— July 22.

Se as bs fa 22.55 19.81 100.00 100.00 These analyses show that the composition of honey-dew collected with several days’ interval has not remained the same. No doubt one has no right to expect that the composition should remain precisely identical; what, however, is remarkable is the analogy which exists in composition between the honey-dew of the Lime and the manna of Mount Sinai analysed by Berthelot. Its com- position is, in fact, identical with that of the honey-dew collected on August 1. Cane sugar ... i. fe a ne ... 65 Inverted sugar ae b wae rh ae ae Dextrine eas Si sik pe Af woe 20 100 It is a discovery not without interest to have found the manna of Mount Sinai in the Vosges. In attempting to compare by analysis the quantity of honey-dew existing upon the leaves of the Lime which was affected with the saccharine matter contained in the leaves in their normal state, we arrived at the following result :— In 1 Square Metre of Healthy Leaves :— Cane Inverted : Weight in Sugar. - Sugar.

The amount of manna, therefore, which exudes from the affected leaves is considerable, especially when one takes into consideration the amount of dextrine, a substance which does not exist in the healthy leaves at all.* From calculations made upon a tree of the same age and size, the leaves of the affected Lime-tree would have a surface of 240 square metres, or rather of 120 square metres (equal to 145 square yards), since the manna only covers one side of their surface. It would result from this, that on July 22, 1869, the Lime bore 2 to 3 kilogrammes (equal to about 4 to 7 Ibs.) of honey-dew, reckoned in a dry state. In the normal conditions of vegetation the saccharine matters elaborated by the leaves, under the influence of light and heat, are distributed through the organism of the plant with the descending sap. In the abnormal state, which determines the production of » the honey-dew, the saccharine matters are accumulated at the upper surface of the leaves, either because the movement of the sap is interrupted, or because it is retarded by the viscosity resulting from the formation of dextrine. The production of honey-dew cannot be due merely to meteoro- logical influences—to the effect of warm and dry summers. No doubt the Lime of Liebfrauenberg secreted it during a summer when there were periods of high temperature, accompanied by great dryness ; we must not, however, lose sight of the fact that it was a - single tree that was attacked by the malady, and that at a little distance there were Limes which were perfectly healthy. It has been supposed that aphides, after having drawn the honey-dew from the parenchyma, discharge it again scarcely altered; but it is contrary to the results of analysis to assign it a composition similar to that of leaf-sap. It is, however, admitted that certain insects possess the faculty of determining the production of manna. Thus it is to the punctures of a coccus that Ehrenberg and Heimprich attribute the formation of the manna which is still found on the mountains of Sinai. The manna falls to the ground from the air (that is to say, from the summit of a tree and not from the sky). The Arabs call it man, and they, as well as the Greek monks, collect it to eat upon bread in the same way as honey. I have myself seen it fall, collected it, and brought it to Berlin with the plant and the remains of the * [The occurrence of dextrine in the living tissues of plants is at the most hypothetical. Sachs, Phys, Vég. (Fr. ed.), 377.] BOUSSINGAULT ON HONEY-DEW. 5 insect. This species of manna is produced by Zamarix mannifera, Ehr. As with many other mannas it is the result of the punctures of an insect, which in the present case is Coccus manniparus, H. & Ehr. (Berthelot, Ann. de Chim. et de Phys., sér. 3, 1xvii., 83.) The manna, consequently, collected in 1869 at Liebfrauenberg had not the same origin as the Sinai manna, though it had the same composition. At the time of its appearance upon the Lime no insects were observable. It was later that a few aphides were seen glued upon a certain number of the leaves. I have already stated that after having washed the extremity of a branch, glutinous points were seen gradually to rise; at first scarcely perceptible, they increased each day, so as finally to cover the whole of the upper surface of the leaf. This slow and pro- gressive development of the honey-dew was clearly effected with- out the intervention of aphides, which did not make their appearance till subsequently, like the flies and bees, either to feed upon the secretion or to pilfer it. [In a subsequent numberof the Comptes Rendus'(Feb. 12) Harting states that honey-dew is produced by Aphis tilie, which, living: on the under surface of the leaves of the Lime, drops its excrement on the upper surface of the leaves beneath. Analysed by Gunning at Amsterdam, it proved to consist of cane-sugar. Boussingault remarked, in reply, that the manna of Liebfrauenberg, like the Sinaitic manna analysed by Berthelot, contained, in addition to cane- sugar, fruit-sugar and dextrine. He added, also, that the leaves of the Lime contain eonsiderable amounts of cane-sugar almost pure, the origin of which could not be attributed to insects. _A paper by Goéthe (Giwvres d@’ Hist. Nat., par Martins, pp. 321 —3828) contains a similar conclusion. He says (p. 324): ‘‘I have seen Limes, of which the leaves seemed varnished, but where not a single insect was visible. The juice is secreted by the plant itself.” Mr. Hanbury informs me that he has noticed the exudation of a saccharine matter from a Canella, and that after repeated cleansings it still made its appearance. He has seen also the occurrence of minute crystals of sugar upon the corolla of the Azalea. De Candolle. mentions the same thing in Rhododendron ponticum (Phys. Veg. i., 288). This is, however, different to the secretion which takes place on leaves, because it is probably merely due to the loss of water from the flower preparatory to fading. De Candolle remarks that granular secretions are found on the young shoots of the Larch, and are collected locally under the name of manna of Briangon; they also occur on Salix alba, and upon 6 ROYAL HORTICULTURAL SOCIETY. some other trees. ‘‘ We cannot affirm,” he says, “ either that-they are a natural excretion, or that they are produced by insects” (Z.c., p. 240). Dr. Masters states in the TZreasury of Botany (p. 88) that a manna-like substance is produced from species of Alhagi, and that it is an exudation from the leaves and branches of the plant only appearing in hot weather. Saline secretions from leaves have been more frequently observed. De Saussure states that an accumulation of saline matters at their surface often occurs in garden vegetables; transpiration being impeded, the leaves are ultimately destroyed (Récherches, 264, 265). De Candolle found a saline secretion from the leaves of a Reaumuria to consist of carbonates of soda and potash* (Phys. Vég. i., 237).—W. T. D.] [Note read May 1.] My attention has been drawn by Dr. Masters to two papers in the Bull.de la Soc. Bot.de Fr. for 1867, which advance a view of the origin of honey-dew quite different to that held by Boussingault. The method of investigation was exactly similar; the leaves were washed, and the mode of accumulation of the honey-dew subse- quently was described in almost the same words. It is attributed, however, not to an exudation from the plants, but to the excretions of parasitic insects which were to be found on the foliage above that on which the honey-dew made its appearance, The insects, it is stated, have the power of projecting their excretions a distance of 4—5 inches, and it is thought that the action of the wind would convey them even further. Riviere appears to have been the first to observe this curious habit, and to have been confirmed by other entomologists. After the honey-dew had attained a thickened con- sistence it became the seat of growth of various microscopic Fungi, referred to the genus F'umago | but subsequently distributed amongst Capnodium, Cladosporium, and Antennaria (see ‘‘ Journal of the Royal Horticultural Society,” 1849, pp. 243—260) |, giving the plant a blackened appearance. The invasion by a host of aphides of two Lime-trees resulted in the blackening of a terrace which they over- shadowed, and of the seats placed upon it. In the case observed by Boussingault it is difficult to think that so careful an observer would not have satisfied himself thoroughly of the absence of — * Mr. Douglas, of Loxford Hall Gardens, Ilford, stated after the meeting that he has some Orange-trees at the back of a Cucumber-house which are frequently affected with honey-dew, though no green-fly ever gets near them, and that he has long been perfectly satisfied that honey-dew is not the result of insect agency. DR. BOSWELL-SYME ON FERTILISATION OF GRASSES. 7 aphides from the Lime-tree he examined. Moreover, it was only one tree which was attacked; had aphides been the cause of the honey-dew, it is hardly likely that other trees at a little distance would have been, as was the case, perfectly healthy. The conclu- sion appears to be that while in some cases honey-dew is due to the presence of aphides, in others it is an independent result of a diseased condition of the affected plant. W. T. D. II. On the Fertilisation of Grasses, By J. Boswett-Symez, LL.D., F.L.S. | [Read April 17, 1872.] Tarover the kindness of Professor Thiselton Dyer I have had an opportunity of reading Dr. Spruce’s paper on the ‘‘ Fecundation of Grasses” (Journ. R. Hort. Soc., n.s, ii1., pp. 4—9.) As I do not find in it any record of observations bearing on the fertilisation of Cereals, there is no necessity for me:to discuss the opinion expressed ° by Dr. Spruce on the subject of the cross-fertilisation of Wheat. There are, however, two points in which his experience of South American Grasses is at variance with what occurs among our British species—first, the change of colour of the anthers from some shade of purple to yellow and back again to purple; and second, that ‘‘ the absence of odoriferous flowers from the Grasses seems to show that insect aid is not needed for effecting their fecundation, but does not render its accidental concurrence a whit less unlikely,” which seems to imply that insects are not attracted by inodorous flowers, and as a special application of this, that Grasses when in flower are not regularly visited by insects. . First, in British Grasses and those ordinarily cultivated there are a few which have their anthers always purple (Corynephorus canescens and Molinia caerulea for example); there are many in which they are pale yellow or yellowish-white (¢.g., Spartina, Nardus, Lepturus, and all the commonly-cultivated Cereals) ; there are many also in which some individuals have purple, and others of the same species have yellowish-white anthers (¢.g., Alopecurus pratensis, A. geniculatus, Phleum pratense, Anthoxanthum, Dactylis). Butin this case we never find the two colours of anthers on one root. My attention was directed to this by the Rev. W. W. Newbould, who wished -me to see if there were not other differences between the white and 8 ROYAL HORTICULTURAL SOCIETY. purple-anthered forms of -Alopecurus pratensis, but I have been unable to find any. I was induced to examine other Grasses in which similar differences in the colour of the anthers occur, in order to assure myself that the two forms of Alopecurus pratensis could not be separated even as named varieties. In most cases the anthers fall off without changing colour, but in a few species (Alopecurus pratensis, A. geniculatus, A. agrestis, Dactylis glomerata) they change from purple or pale yellow to fulvous brown; but this change does not take place unless they are empty and dead. I suppose it is much as we see in a beech hedge on which the leaves remain in winter, but changed to brown. On the second point, in Britain most of the plants whose flowers are most attrac- tive to insects are either scentless or with a disagreeable odour ; look for example at Salix, Centranthus ruber, Silene inflata, Lilium Martagon, Echium vulgare; of these Lilium Martagon is the only one with a powerful odour, but very few persons would call it an agreeable one. In the special case of Grasses, I refer to one of the best authorities for Lepidoptera, Dr. H.G. Knaggs.

On Deal sandhills I have noticed a similar phenomenon, when the attraction was the flowers of Psamma arenaria; and at Balmuto Dactylis glomerata is attractive to moths, though less so than the two other Grasses named.

As to other Grasses, Dactylis glomerata has pollen in the anthers at the time they appear. This is readily seen by striking the culms with a stick, when a cloud of pollen flies out. Anthoxanthum odoratum is protogynous, but some of the anthers are protruded before ali the stigmas of the panicle are. -Alopecurus pratensis is protogynous; all the stigmas in a panicle are protruded about twenty-four hours before any of the anthers are. This was tested by placing bits of paper on the growing plants as soon as the stigmas appeared. III. On Recent Progress in the Scientific Aspects of Horticulture. By W. T. Tuisrtron Dyrr, B.A., B.Sc., Professor of Botany to the Royal Horticultural Society. . [Introductory Address at the Birmingham Congress, June 26, 1872. ] Ir has fallen upon me, rather as a matter of official obligation than from any special qualifications, to open the proceedings of this Con- gress with some remarks upon the more theoretical matters connected with horticulture which possess anything of novelty. First of all, however, it may be well to consider in what direction the utility of such a meeting as we are now holding appears principally to lie. If I may express my own conviction, it is in the advantage of having an opportunity of discussing in an informal way matters connected with horticulture which from time to time come into prominence. I do not think it necessary that the subjects brought forward should be particularly novel or particularly recondite, but only that they should be such as happen to occupy our minds. — Nor do I think that the value of the Congress is to be estimated by the success or dulness of any particular meeting ; on the contrary, * Confirming the observations of Dr. Boswell-Syme, ‘‘ Journ. of Botany,” 1871, p. 373, and Bidard, ‘‘ Comptes Rendus,” 1869, p. 1486. 10 ROYAL HORTICULTURAL SOCIETY. what we should keep in view is, the usefulness of having an annually recurring occasion for the discussion of matters which during the preceding year have fixed our attention. Many persons, it may be said, who pursue horticulture as a means of livelihood care little for any addition to their knowledge which does not imply also an addition to their gain. They are not to be blamed; nor are we likely, ina meeting like the present, to neglect the interests of practical men. But there are others who desire to know, merely for the sake of knowledge, more than those who have gone before them have known about the facts of plant life. Ido not think that men of practice will object to our discuss- ing amongst other subjects some which seem to possess no immediate practical bearing. It was thought, however, this year, that there might be several advantages in roughly classifying our business. Nevertheless, it must be remembered that both science and practice merge under the general head of knowledge. A man who finds out a better method of growing some plant adds to what we know, just as another adds to it who makes out some obscure point in vegetable structure. The real difference between science and practice con- sists in this, that science takes the whole field of Nature for its territory, while practice contents itself with a particular portion of it. I am convinced, however, that practical men, if they were so disposed, could with little trouble contribute very usefully to purely scientific knowledge. The harvest of factsis ready ; it only needs those who will gather it systematically. To record carefully facts — of importance is to confer a benefit upon science which it is im- possible to estimate too highly. Itis not necessary to devise at once an explanation, or to hesitate too much if the matter does not square with preconceived ideas ; it is only necessary to be sure, as far as we can be so, that we have observed correctly. Turn over the volumes of Mr. Darwin’s ‘‘ Animals and Plants under Domestication.”’ Every page is noted with references to ephemeral and apparently trivial sources of information, of which it was reserved for this sagacious writer to appreciate the value. Noone need despair of a carefully-recorded fact failing to find its place and use. How important it would be to thoroughly comprehend the principles of variation! Yet of the numerous persons who raise new varieties of plants, how few there are who record anything of their experiences! Some, no doubt, have acquired a kind of intui- tive tact in working with plants. Still, anything like systematised knowledge in the matter is still to a great extent a want to be sup- PROF. THISELTON DYER ON SCIENTIFIC HORTICULTURE. 11 plied. Mr. Darwin has grouped together in a most admirable way the facts, in many cases very scanty, which he had been able to collect before writing his book. On many of these subjects it would be very desirable to obtain the fruits of more ample experience. I am glad, therefore, to say that Dr. Denny is about to read us a paper on the relative influence of parentage in cross-fertilising plants, and I think I may point to his work as a proof of the fact that some attention to its theoretical bearing is no obstacle to its practical success. An accumulation of evidence on this subject is very desirable. A more extended study of bud-variation is also a matter which I would commend to your notice. Mr. Darwin arrived at the conclusion that bud-variations, when they occurred at all, usually assumed at once a decided and permanent character. At the same time he thought that this might possibly be a delusion from slight varieties being overlooked. The attention whichis now paid to variegated Pelargoniums seems to offer an opportunity of seeing whether this conclusion is really true. Again, from time to time various curious facts have been recorded with respect to the direct influence of the pollen, not on the seed alone, but also on the female parent. Mr. Anderson-Henry has stated that the flowers of a pale Calceolaria became stained after the application to the flowers of the pollen of acoloured kind. Maximowicz has described a change in the shape of the capsule of a Lily in the direction of that belonging to the pollen-parent. Again, the fruit of different cultivated Cucurbitacee has by more than one observer been stated to be affected if the pollen of some other kind has got access to the flowers. None of these cases are completely free from ambiguity, and the whole matter might easily be tested by those who occupy themselves much with artificial fertilisation. The instances would certainly be rare, but if they could be established free from all reasonable doubt it would be a matter of very great interest. The difficulty lies in the possibility of the supposed in- fluence of the pollen being really due to a bud-variation. If, how- ever, the same kind of variation were to follow more than once in the same plant the application of foreign pollen, it would be almost certain that this was the cause. 4 prior? we know that it is not im- probable, since analogous cases occur amongst animals.* * Maximowicz’s paper is translated in Journ. R. Hort. Soc. n.s. iii. pp. 161—168; Mr. Anderson-Henry’s case of the Calceolaria will be found in n.s. vol. ii, p. 77; for Cucurditacee see Darwin, ‘‘ Animals and Plants under Domestication ” i., p. 399. 42 ROYAL HORTICULTURAL SOCIETY. The nomenclature of plants is a subject upon which it is becoming more and more necessary to have some common under- standing between botanists and horticulturists. At the last meeting of the Floral Committee a plant was submitted to it with the name of Lilium bulbiferum Thunbergianum aureum nigro-maculatum. As Lilies are now favourite objects of culture, this name is quite likely to receive further distinctive additions. Now it seems to me that for trade purposes such a name must be almost a deterrent to purchasers. People grumble often at a plant having two Latin names ; they will grumble still more at its possessing half-a-dozen. The remedy, I think, lies in adopting De Candolle’s suggestion— that we should restrict Latin names to species and varieties occurring spontaneously in Nature, and should give to forms which make their appearance in gardens names ina modern language. This expedient would tell us in a moment whether any particular plant was or was not of garden origin, and from the language the name would also inform us whether it was raised by English, French, or German horticulturists.. Still, certain modifications of botanical nomen- clature must, I think, be tolerated in horticulture. In the first place, reliance has often to be placed upon distinctions which, in a botanist’s eyes, seem of little importance. It cannot be objected very much, therefore, if very well-marked varieties or sub-species are treated as if they were species for purposesof garden nomenclature. If there is some tangible character by which they can be dis- tinguished from their allies, itis easy to ascertain by reference to books the rank that botanists give them. It is often necessary, as more is known about the plants which grow upon the earth’s surface, to change generic and specific names. There is usually a good reason to be assigned for doing this, but it is undoubtedly a grave source of inconvenience. Botanists will not, therefore, blame horticulturists if they keep to many of the old names, of which it is generally easy to determine the most recently recognised equiva- lent. Odontoglossum crispum is the original and lawful name of O. Alexandra, but it is not now very likely to supplant the name most in use. When plants have been placed, however, from the first in genera which are obviously wrong, I think an effort should be made to give them their proper position. Having made the concessions above mentioned, I feel that it is an absolute duty to protest against plants avowedly of garden origin having, under any circumstances, names given to them which are of the same form as those which are given to species spontaneously occurring in Nature. The case — of hybrids is an exception, but it would be better if the name PROF. THISELTON DYER ON SCIENTIFIC HORTICULTURE. 13 given to these always indicated both the hybrid origin and the parentage. There is one branch of science intimately connected with horticulture in which we are far from reaping at present the practical benefit of knowledge. This is meteorology. It is too much, I am afraid, to hope that we shall ever possess the slightest control over the asperities of weather, but it is scarcely too much to look forward to improved methods of foretelling what is in store for us, as well as improved methods of obviating its effects. The study of careful records of daily observations will, no doubt, eventually reveal not only some of the causes that influence weather itself, but will also throw light upon changes in public health, with which it cannot be doubted that weather is closely boundup. Such records the Royal Horticultural Society kept at its Chiswick Garden for forty-four years, and the results of the observa- tions have been lately printed by Mr Glaisher at the Society’s expense. The practical information which can be deduced from this volume is not, perhaps, considerable; it is, however, a contri- bution to the accumulated stock of records which will one day find their utilisation. The mean temperatures at Chiswick, as deduced from the whole observations of forty-four years, starts from its lowest point of 35:8 deg. on Jan. 6, and rises more or less gradually to its highest, 64:4 deg., on July 17. If climate would only pursue this even course with some approach to constancy, vegetation would follow it with a clockwork regularity. We know, however, to our cost, that it does not do so, and very considerable deviations take place to one side or the other of the mean temperature. Both are injurious. A premature development of vegetation lays it open to subsequent injury, and comes to much the same thing, as regards its effects, as a late frost. What the horticulturist really has to fight, then, are the effects of cold. The precise mode in which plants are affected by it is hardly completely known. In many cases, no doubt, the vital properties of the protoplasm contained within the cells receive an injury from the direct effect of low temperature from which there is no recovery. In other instances death is not the inevitable result even from freezing ; but, as is well known, if thawing be gradually effected, no great harm will be suffered. Some curious experi- ments published by Becquerel appear to show that cold below the freezing-point, like the temperature of boiling water or the electric discharge, produces an alteration in the cell walls, which renders 14 ROYAL HORTICULTURAL SOCIETY. them more pervious to fluids, and therefore no longer capable of retaining their cell contents. It appears to me that the pyramid fruit-trees and espaliers, which are now so much grown, are peculiarly exposed to the effects of frost, as they are pruned so that each branch overhangs, and consequently protects any below it to the least possible extent. It ought, nevertheless, to be possible to devise some cheap and effective way of protecting temporarily trees of this small size from frost. In view of any expedients of this kind, any means of anticipating their need would be of the greatest value. It may be well, therefore, to mention that in spring a dry state of the air, indicated by any very considerable difference in the readings of the dry and wet bulb thermometers, is likely to be followed by frost. The reason is simple: the night frosts, which injure vegetation, arise in the main from the loss of heat from the earth’s surface by radiation. If there is much moisture present in the air this loss of heat is impeded. The luminous heat radiated from the sun passes through atmospheric moisture with little impediment, but the obscure or non-luminous form in which the earth radiates it back again is caught by it, as it were, ina trap. On May 17, at Blackheath, near London, the air was nearly saturated with moisture, the degree of humidity being represented by 94 deg., and the lowest temperature of the air by 44deg. Both tempera- ture and humidity fell, part passu, till May 20, when the first stood at 82°6 deg., and the other at 69 deg. It would be of the more importance to have warnings of the probable occurrence of low temperature, because Mr. Glaisher has shown from the Chiswick observations that periods of deficiency of temperature below the mean are often prolonged to as much as a fortnight. In the forty-four years there were eighty such. I feel strong hopes that the telegraphic communications about the weather, which the Meteorological Office now collects from stations in the British Isles and Western Europe, will eventually lead to warnings of probable falls of temperature being obtained. The apparently paradoxical fact that the temperature often falls lower, and plants correspondingly suffer more from frost, in low grounds than in those which are adjacent and higher, has often been observed, and it is important to remember it as a practical point in planting and laying-out grounds.* The ex- —_—_ * See Dines ‘On the Temperature of Hill and Valley,” in the Journ. PROF. THISELTON DYER ON SCIENTIFIC HORTICULTURE. 15 planation may be partly due to the downward gravitation of air cooled at the surface of the higher ground, and its consequent collection in low-lying places and hollows.* In every department of scientific work it from time to time happens that announcements are made which take completely by surprise those who know what has really been made out by legiti- mate investigation in the subjects upon which they bear. Never- theless, the outside world always takes them up with more or less_ of uncritical faith. A paper published during last year by General Pleasonton, ‘‘On the Influence of the Blue Colour of the Sky in Developing Animal and Vegetable Life,’ appears to me to have received a great deal more attention than its utter absence of any genuine scientific character deserves. Subsequently pre- sented to the French Academy, it has been the subject of an article by Duchartre in the Bull. de la Soc. Cent. d’Hort. de France. This writer points out some of the mistaken scien- tific views held by General Pleasonton, but though apparently Meteor. Soc. 1872, pp. 100—102. The places compared were Denbies, near Dorking, 610 feet, and Cobham, six miles distant, 65 feet above the sea-level. The maximum temperature of the hill is below that of the valley, the differ- ence averaging from 3 to 3}.deg. But in times of extreme cold the tempera- ture on the hilltop never descends so low as in the valley. Out of forty-three occasions when the temperature has been below 24 deg. at both places, the average on these occasions upon the hill has been 23°3 deg. against 18-9 deg. at the valley. The temperature has been six times below 10 deg. at the lower station, giving an average of 6 deg., while on the hilltop upon the same height it averaged 15 deg. On the morning of December 31, 1870, the minimum at Cobham was 1:2 deg., at Denbies 14 deg, The popular opinion assigned for this difference is that the air of the hill is drier than that of the valley ; the observations give no foundation whatever for such an opinion. Professor Ragona-scina (Proc. Meteor. Soc. ili.), and Mr. Glaisher (Proc. Meteor. Soc. v.), have arrived at the conclusion that through the day the higher strata of air are the colder, that towards evening they approach nearly to equality, but that at night the higher strata of air are the warmer. * The stratum of air in contact with ground covered with vegetation cools under nocturnal radiation sometimes 8, 10, or 12 deg. Fah. below that of the air a few yards above. Thus Humboldt and Bonpland found dew on the surface of the ground when the temperature of the air at some little distance above it was 70 to 80deg. The air cooled in this way would gravitate into hollows and low-lying places. This seems to explain the fact observed by Martins that figs, olives, laurels, etc., perished in low parts of the Botanic Garden at Montpellier, while they escaped a few yards higher in equal conditions of shade (Becquerel “ Sur les Foréts et leur Influence climac- _ térique,’’ Mém, de l'Institut 35, pp. 456—459). 16 ROYAL HORTICULTURAL SOCIETY. inclined to reject the whole narrative as a hoax, thinks that it is vouched for by testimony too respectable not to require some explanation. For my own part, having carefully read the original paper, I do not believe, for reasons I have elsewhere stated,* that blue or violet light had anything to do with the extraordinary growth of the Vines, supposing that really to have taken place as described. I am slow, indeed, to comprehend Low such a physical condition as exposure to blue light can be equally beneficial to the growth of Vines, the rearing of poultry, and the invigoration of the constitution of invalids. The erroneousness of the facts argued from, the absence of all knowledge of modern publications in vegetable physiology, and the wildly crotchety theories, such as electricity having produced the giant trees of California, disincline me, I must confess, to attach any serious weight to either General Pleasonton’s views or his results. I must not occupy your time with longer remarks. I will only, in conclusion, call your attention to the useful summary of the history of the Phylloxera vastatriz, given by the President of the _ Linnean Society in his annual address, and printed in ‘‘ Nature” for June 13 last, and also to the completion by Decaisne, with the 10th volume of the ‘‘ Jardin Fruitier du Museum,” of the history of cultivated Pears. IV. The Relative Influence of Parentage in Flowering Plants. By J. Denny, M.D. [Read at the Birmingham Congress, June 26, 1872.] One of the chief objects of my paper is to promote the study of a subject full of scientific interest, and of the greatest importance to the practical horticulturist, but which, for the want of accumula- tion of data derived from accurate experiments, at the present is involyed in much obscurity. ; If we could, by the observation of results acquired through the medium of a series of carefully-performed experiments in artificial fertilisation, obtain any reliable evidence indicative of the relative influence the male (or pollen) and the female (or seed) parents bear * Gard. Chron. 1872, p. 396. DR. DENNY ON RELATIVE INFLUENCE OF PARENTAGE. LL? in the production of their progeny, it would assist us immensely in carrying out our designs for the improvement in the form and - colour of our flowers, and the quality of our fruits and vegetables. If, for instance, we knew that either parent was prepotent in con- veying to the offspring certain qualities, say, of flavour and aroma, or of size and form, as regards our fruits, or of colour, perfume, form, or substance in our flowers, we should be able to form some approximate idea of the result that would follow our fertilisations. A knowledge too of the ancestry of the varieties we purpose em- ploying would also be desirable, to enable us to make allowances for the modifications likely to ensue from the tendency to reversion towards an ancestral type—a propensity which seems to be inherent in all plants that have been much changed from their original state by artificial breeding. It would also be a matter of scientific interest, as well as perhaps of practical importance, to know if the proportionate in- fluence borne by the respective parents in crossing varieties is the same as in crossing species ? As the admission of fecundation is no test of the plants employed belonging to the same species, have we any well-defined line of demarcation or practical test by which we can distinguish between species and varieties, so that we may know when to employ correctly the term hybridisation, and when cross-breeding ? Does there exist any real difference in the powers or quality of the pollen of the long and short stamens from which we may expect to derive any specific effect on the progeny by the exclusive employment of the one or the other, or to succeed more readily in effecting difficult crosses ? Do certain states of the atmosphere, and if so what apparent conditions of it, favour fecundation ? Can any clue ve obtained, or suggestions offered, to account for the antipathies that are found to exist between apparent varieties, as well as affinities between what are considered by botanists to be distinct species, precluding fertilisation in the former and rendering it easy in the latter ? These are a few of the most important points that are constantly occurring to the practical horticulturist. To how many of them does our knowledge admit of a satisfactory reply being given ? From early youth I have taken much interest in artificial fer- tilisation, but have kept noregister of my crosses or their results, until the controversy arose respecting the tricoloured Pelargoniums, as to whether their leaf-markings could be reproduced by fertilisation VOL. Iv. Cc 18 ROYAL HORTICULTURAL SOCIETY. and seed, or whether they were sports only, and owing to a diseased condition of the plant. To ascertain for my own satisfaction the truth upon these points, as well as with the object of obtaining, if possible, some informa- tion regarding the relative powers the respective parents exert over their progeny, I commenced a series of experiments upon the scarlet section of the Pelargonium, employing varieties of the most opposite and varied character, and crossing them in every conceivable way. I conducted these experiments, too, with the utmost possible care and minuteness of detail, both as regards the methods I adopted for preventing self or insect fertilisation, to ensure the fertilisation being effected by the desired pollen only; and as regards the keep- — ing an exact register of every cross, as well as a record of their results. By this means I soon arrived at a satisfactory conclusion as regards the points at issue respecting the transmission of variegation of the foliage by fertilisation, from the fact of its being manifested to a greater or less degree, in as large a proportion as from 50 to 60 per cent. of the offspring, where the green zonal had been fertilised by the pollen of the variegated. I also obtained some valuable in- formation indicative of the powers the respective parents exert upon various other points in connection with the transmission and modifi- cation of the foliage and habit of the plant, as well as of the colour and form of the flower. From the information thus derived, I am of opinion that by careful and persistent fertilisation, under the guidance of the ob- servation of results, it is possible produce almost any modifica- tion in the character and habit of our plants, or variety of colour and form in our flowers, we might desire. For I am satisfied that by these means we possess a much greater power of moulding our tlowers in accordance with preconceived design than is generally supposed ; and, moreover, I think it possible that ultimately some insight may be obtained into the working of the laws that govern procreation in the vegetable kingdom, and that produce variation in our fruits and flowers. The result of my experience derived from these experiments, as regards the relative influence of the parents, certainly tends in the reverse direction to my previous ideas, which were derived from books, from which I gleaned that the form of the flower and con- stitution and habit of the plant were inherited from its mother, whilst the colour of the flower only was supposed to be conveyed ad DR. DENNY ON RELATIVE INFLUENCE OF PARENTAGE. 1? by the father. The recorded results of my crossings indicate an immense preponderance of influence over the progeny on the part of the father in all respects—in colour and in form, in the quality, in size and substance of the flower, as well as in the production of variegation of the foliage, and in the habit and constitution of the plant also, provided the plants employed are of equal strength. I wish to be distinct upon this point of relative strength of the parents, beeause it seems to me that upon the equality or the preponderance of strength on either side very much hinges as regards the results we obtain from our crossings, for power of con- stitution exerts most unmistakable influence, and where it prepon- derates on the part of the seed-parent it will modify the otherwise prepotent influence of the pollen-parent. This modifying influence manifests itself most as regards the habit and foliage of the plant, and next as regards the form and substance of the flower, and lastly as regards the production of a blend in the colour of the flower. To illustrate what I mean, if the pollen of a flower of Pelar- gonium, of brilliant and decided colour, but of bad form and substance, belonging to a plant of weakly constitution, be applied to the stigma of a finely-formed, thick-petalled flower of a plant possessing a vigorous constitution, some few of their progeny will be improved in the form and substance of the flowers and habit of plant, with, perhaps, some blend in the colour, showing that the preponderance of vigour in the seed-parent had exerted a certain amount of influence; but even under these circumstances much the greater proportion of the progeny would either resemble the father in all respects, or show reversion towards former proge- nitors or an original type. | I will quote a case or two in point from my note-book. During the summer of 1869 I raised about 140 seedlings from crossings between Lord Derby and Leonidas. In about half of these Lord “Derby was the pollen and Leonidas the seed parent, and half resulted from crosses effected the reverse way. The flower of Lord Derby possessed the fine qualities, both as regards form of petal and smoothness of texture, but was wanting in depth and brilliancy of colour, and also in substance ; and the plant was deficient in vigour of constitution as compared with Leonidas. The flower of Leonidas was much inferior as regards form and quality, but of greater sub- stance and brilliancy of colour, as well as larger than that of Lord Derby, and the plant possessed a vigorous constitution. These seedlings flowered during the spring and summer of c 2 20 ROYAL HORTICULTURAL SOCIETY. 1870. Of that portion in which Lord Derby was used as pollen- parent and Leonidas as seed-parent, about one-third resembled in all respects their father ; a few produced flowers very considerably in advance of Lord Derby in size, in substance, and in colour of the flower, and with a superior constitution and habit of plant, showing the influence of the mother in combination with the father’s. (I would instance Sir Charles Napier, which resulted from this cross, asan example.) Of the remaining two-thirds, a few very nearly resembled Leonidas in flower, except being paler in colour, and having a somewhat increased breadth of petal, resulting from the father’s influence (for instance, Iago); but a large propor- tion were inferior, showing reversion towards an ancestral type. Of that portion in which Leonidas was used as pollen and Lord Derby as seed parent, nearly -half resembled in all respects Leonidas, and the rest were much inferior; not one showed that any appreciable amount of influence had been exerted by the mother towards improvement. It will be observed that in this cross the pollen-parent possessed both the inferior flower and the most powerful constitution also. As regards the habit of these seedlings, they were all more robust than those of the mother. The same season I raised about sixty seedlings from a cross between Celestial and Lord Derby. Celestial, which was used as pollen-parent, possessed a brilliant magenta-coloured flower, but of very bad form and substance, with a weakly constitution. From this batch of seedlings a few produced flowers of a colour very similar to the father’s (but somewhat less brilliant), and with a great improvement as regards the form, quality, size, and sub- stance of the flower, accompanied, too, with a fair habit and consti- tution of plant, showing a marked influence. on the part of the mother, which in this cross was decidedly the stronger of the two parents. Ianthe resulted from this cross. The remainder of this batch were mostly of very bad form and quality of flower, and weakly constitution ; but there were some very brilliant and novel colours. Interesting examples of colour blending, amongst them were carmine, rose-crimson, pinks, and vivid scarlets—some in all respects resembled Celestial. My large seedling nosegay Wellington was the result of a cross between Le Grand (nosegay) and Leonidas, Le Grand being used as pollen-parent. Here the plants were about equally vigorous. Wellington resembles in the character of its flower its father, but with an increased breadth of petal derived from its mother; the colour of the flower is nearly that of the father’s also, but it is some- DP, DENNY ON RELATIVE INFLUENCE OF PARENTAGE. yy | what a blend, the purple hue of Le Grand and the deep scarlet of Leonidas havingy produced a very dark crimson scarlet, almost maroon. The foliage, too, of Wellington is most distinctly of the nosegay type; its habit still more vigorous than either parent. In breeding for variegates, and using the variegates (which, as -a rule, are wanting in vigour) as pollen-parents, and the robust green zonals as seed-parents, about half the number of their progeny showed variegation, and possessed weakly constitutions, the remainder being green zonals; upon the order of procedure being reversed, by which the pollen-parent became the parent of the greater vigour, the mother’s influence was almost nz. I believe that it is owing to the existence of a difference in the vigour of the respective parents that the production of novelties and varieties in our flowers (and probably in our fruits too) mainly depends, and that were it not for a preponderance of power on the mother’s side, the progeny would almost invariably resemble the father ; and hence the immutability of our flowers and vegetables, which are annually reproduced from seed, the result of self- fertilisation. But I consider another source of variation exists in the tendency in all flowers (and fruits) that have been artificially bred up toa state far in advance of their original condition, to revert towards former progenitors (especially under the influence of self- fertilisation), by which means new combinations of ancestral pro- perties are formed, and therefore new varieties. Even under artificial fertilisation I find in the Pelargonium this tendency to reversion to exert very considerable modifying influences. I have especially observed it as regards the colour of the flower ; for instance, the magenta shades that have been produced upon the scarlet Pelargonium have resulted from the crossing of pinks upon scarlets; and very many of my seedlings—the offspring resulting from the crossing of two magenta-coloured flowers—have pro- duced pink ones as well as scarlets, showing reversion to both the colours of their immediate ancestors. It is a point worthy of observation whether the colour of a flower. or a change in the character of a plant that has recently been obtained are conveyed to their offspring in the same proportion as to numbers and with the same certainty as those of long standing. I think not. A remarkable instance of reversion as regards foliage occurred in two out of a number of seedlings raised this spring from Violet Hill Nosegay as seed-parent, crossed by Ianthe, with the object of obtaining variety in the flower. Two of this batch of seedlings 22 ROYAL HORTICULTURAL SOCIETY. have come variegates. Now Violet Hill was bred for variegation, and was planted out at Messrs. Henderson’s establishment at St. John’s Wood in the spring of 1864, with a view to its breaking into variegation, which it did not do; but it was selected, and subse- quently sent out, for its flower, and on account of its dwarf habit of growth. : My notes would furnish innumerable examples in support of the theories I have founded’ upon them, did time admit of my going further into detail. I would observe that I have purposely quoted the results of crossings which produced varieties that have been sent out by Mr. W. Paul, that they might, if desired, be referred to, and compared with their parents. A close analogy seems to me to exist between the vegetable and the animal kingdoms as regards the ill effects produced by breeding in-and-in, and the good resulting from crossing opposites, for I find it to be necessary for the maintenance of improvement in the flower, and the constitution of my seedlings, to introduce fresh varieties to breed from annually; and I find that crossing two flowers of the finest qualities does not produce such satisfactory results as where one of much inferior quality is employed. Of course it will be inferred from my previous observations that I use the superior quality flower as pollen-parent. I am of opinion that the decadence in many of our old florists’ flowers is owing to their having been bred in-and-in, and from the repeated crossing of flowers of a precisely similar strain and qualities, with the object (and probably supposed only means) of reproducing flowers possess- ing certain peculiarities in markings or form, in accordance with the rigid rules prescribed for these flowers. As regards the condition of the atmosphere that favours the effecting of difficult crosses, it would be no easy matter to note with any degree of certainty the precise period of each successful attempt, nor the precise condition of the atmosphere at the time. We read of special crosses having been effected under certain conditions of it, but I have never seen it specified what these conditions were My experience indicates that bright clear weather and the hours of sunshine are conducive to fecundation. I have alluded to the antipathies and affinities we find to exist, without any explicable cause ; for instance, I have found it impos- sible to fertilise three or four varieties of the scarlet Pelargonium (viz., the Duke of Cornwall, Dr. Muret, Beauté de Suresnes, and all that section of the doubles which sprang from Beauté de Suresnes), which to all appearance are mere varieties of the zonal DR DENNY ON RELATIVE INFLUENCE OF PARENTAGE. 23 section, save with one another; and, showing the existence of affinity between what are supposed to be distinct species, I have fertilised without much difficulty a variety (peltatum elegans) of the Ivy-leaved section by the pollen of the zonal. I have also alluded to the possible difference in the respective influence of the parents in true hybridisation. Upon this point I have not sufficient evidence to form a fair opinion; but certainly in the seedlings I have raised between the Ivy-leaved and the zonal sections, their foliage (with the exception of some distinctive evidence of their being hybrids) resembles almost entirely that of their mother, which it will be observed is the reverse of my expe- rience of the results produced between varieties. Much has been written and said upon the difference in the quality and powers of the pollen of the short stamens, and if the supposed difference really does exist, it is a matter of considerable practical importance, and one worthy of further scientific investiga- tion; but my experiments have hitherto failed to satisfy me of their possessing any difference. - In an admirable article upon hybridisation, written by Isaac Anderson-Henry, Esq. (and which at different periods has appeared in nearly all the horticultural journals), he says ‘‘that, owing to the granules of the short stamens being smaller than those of the long ones, they can the -more easily descend the tubules leading from the stigma to the ovaries, and consequently facilitate the OPE of a large-flowered variety, or species, upon a smaller one.’ I have not been able to detect this difference in size, although I have many times placed the granules of the long al short stamens side by side under a powerful microscope; nor, I believe, is it the opinion of physio- logists of the present day that they do descend these tubules at all —in fact, it has been shown that they send down filaments through them to the ovules. The arrangement of the anthers upon filaments of different lengths looks to me like a provision to ensure all parts of the body and legs of the insect coming into contact with the pollen as it passes down the flower to obtain the nectar, thereby rendering the fertilisation of the next flower it visits the more certain. The visible effects of impregnation are frequently manifested with a rapidity almost equalling that of an electrical phenomenon. I have observed the petals of the Pelargonium, which, before im- pregnation, were quite firm, to fall within a few seconds of the application of the pollen to the stigma—a result due, I conclude, either to the immediate diversion of nourishment from the then 24 ROYAL HORTICULTURAL SOCIETY. superfluous part of the flower to the organs of generation, or to the existence in the vegetable kingdom of a power analogous to the nervous in the animal, but of which we are as yet in total ignorance. Lastly, 1 would remark that, to enable reliable conclusions to be drawn upon any of these points, we require an accumulation of data derived from the careful observation of very many un- biassed workers, whose results have been obtained from experi- ments conducted with scientific precision upon all our flowers and fruits. Such an accumulation of recorded facts (if they could be obtained) would prove a source of the greatest interest to the philosopher, by their tendency to throw some light upon the working of Nature’s laws, and could not but afford most valuable information for the guidance of the practical horticulturist; and moreover by freeing horticulture from all empiricism, place it in its true and legitimate position among the modern sciences. [ With regard to the influence of the size of pollen grains upon hybrid-formation, the following seems to be a case in point. It is quoted from the Report of the Massachusetts Horticultural Society for 1872, p. 184:—‘‘ Mr. Wylie found that generally the pollen grains of grapes were of oblong form, while those of the Scupper- nong, the great wild grape of the South, were smaller and more spherical. He found that he could not fertilise the Scuppernong with pollen from other species, but he did succeed in impreg- nating the foreign grapes with pollen from the Scuppernong. ‘His inference was that the pollen-grains being smaller in the Scuppernong than in other varieties, the canal through which they have to pass to reach the ovule in that species is also smaller, and thus he explained the results of his experiments. The smaller grains could pass through the large tube, but the larger grains could not pass through the small tube.” There is the same mis- — apprehension as to the part played by the pollen-grains as is alluded to above, but this does not affect the fact stated.—Eps. | MR. GLAISHER ON TEMPERATURE OF ROOTS OF PLANTS. 29 V. On a Thermometer for Taking Temperature at the Roots of Plants. By James Guaisuer, F.R.S. [Read June 26, 1872.] Tue temperature of the soil at different depths must more or. less occupy the attention of gardeners and agriculturists, and more particularly in relation to the temperature to which the roots of plants are exposed. We possess but little information, even in experimental horticulture, as to the temperature of roots, nor of the luxuriance of some plants compared to others, which probably maybe partly attributed to the different temperatures of their respective roots. We know that improved culture improves plants; we know that temperature exercises a great influence, and it is probable that the temperature which reaches the roots is that which exercises the greatest influence. Considering, therefore, that the ascertain- ment of the temperature to which roots are subjected, in connec- tion with their more or less luxuriance of foliage, of fruits, or of flowers, opens up an unexplored field of information necessary to the complete success of the labours of the gardener an@*horticul- turist, I have for some time considered how best this information could be obtained, and have designed a thermometer with a toler- ably sensitive bulb, which may be placed either at 1 inch, 2 inches, or 8 inches below the surface of the soil—a depth known definitely by a circular plate fixed upon the stem of the thermo- meter by bayonet joints, resting on the surface of the soil at 1 inch, 2 inches, or 3 inches from the centre of the bulb of the thermo- meter. JI have considered it desirable that the whole instru- ment should be encased, both for its safety in carriage from place to place, and when in use that neither stones nor cats should injure it. One of these is exhibited (fig. a), prepared for observation at these depths. The price of this instrument is 12s. 6d., to be fur- nished by Mr. Ackland, of Horne and Thornewaite’s, 128, Newgate Street, under the condition that it has been previously examined and certified by myself as to its accuracy, and that no error so much as three-tenths of a degree shall be present at any part of the scale. An instrument of this form for a depth of 6 inches would be 17s. 6d., under the same conditions of my examination before sale. As most roots are within 6 inches of the surface, these instruments 26 ROYAL HORTICULTURAL SOCIETY. would suffice for such observations; but other instruments for greater depths, on the same principle, could be made as required, under the same conditions of examination. It is exceedingly desirable to be able to ascertain the degree of temperature surrounding roots nourished with different manures, particularly those which readily accept nourishment, and to ascer- tain whether the same manures in the same proportions yield the same temperatures with different species, or whether the tempera- ture, however derived, which is best to bring one species of plants to perfection is the best for other varieties of that species. This instrument has been submitted to the Scientific Committee of the Royal Horticultural Society, under whose auspices, in con- nection with myself, it will be made. VI. Ona Dry and Wet Bulb Thermometer. By James GratsHre, F.R.S. [Read June 26, 1872. ] Aw exact knowledge of the state of the humidity of the air is as important as that of its temperature, in al! closed buildings used for horticultural purposes. When plants are imported from other climates, their more or less capability of acquiring maturity is much dependent on the more or less approximation to the climate from which they came, both in its degree of humidity as well as its temperature. By the use of the dry and wet bulb thermometer, both these elements are known, and the one now exhibited (fig. B) is fixed on a metal frame, so that it cannot be injured by water in the greenhouse. I consider that instruments of this class, for this purpose, should be good and inexpensive. The pair of thermometers, as shown, are very nearly without errors at every part of their scales, and could be used for outdoor determinations of temperature and humidity of the air if necessary. Mr. Ackland (Horne and Thornewaite, 123, Newgate Street) has agreed to furnish these instruments thus seine at 15s. the pair, upon the agreement that he will send them to me for examination before mounting, and sell those only to horticulturists which are furnished with my certifi- cate of their accuracy, and that I am permitted to reject all instru- ments which may have an error as large as three-tenths of a MR.

By J. G. Baxzr, F.L.S., Assistant Curator of the Kew Herbarium. [Read June 26, 1872. ] THERE are two genera of arborescent Liliaces which since the beginning of the century have been distinguished by botanists by universal consent, and which are well-marked from one another both by structural differences and by habit, which seem lately, so far as nomenclature goes, to have drifted into a state of fusion in our collections and trade catalogues in a way that certainly would 28 ROYAL HORTICULTURAL SOCIETY. be protested against if Lilies were either Ferns or Orchids. The two genera to which I refer are Dracena and Cordyline, some members of which everyone knows, and everyone who has a con- servatory cultivates. The Dragon Tree of the Canaries is a plant about which everyone has read, and the great Dragon Tree of Orotava, with a trunk 70 feet high ahd 50 feet in circumference, which has an authenticated history going back to the commence- ment of the fifteenth century, is a prominent item in every bead-roll of vegetable wonders. Scarcely less celebrated, though of course not known so long in Europe, is the invaiuable ‘‘ Ti”? Tree of the Polyne- sian islanders, Cordyline terminalis. Its uses are almost as manifold as thoseofa Palm. Inthe Sandwich, Society, and Fiji groups it serves largely for food. The tuberous root, which often weighs from ten to fourteen pounds, after being baked on heated stones, is said to re- semble closely stick-liquorice in taste and sweetness. Bruised, mixed with water, and fermented, it forms an intoxicating drink ; distilled, an ardent spirit is readily obtained ; boiled before fermenta- tion, a rich syrup capable of being used as sugar is the result. The leaves furnish excellent fodder for rabbits, goats, sheep, and cattle, and are used for this purpose by European settlers. It is often erown for the sake of its ornamental leaves; and the stems, stuck into the ground in a row, soon run up into a firm fence for an en- closure. These are the two best and oldest-known members of the two genera. Now as to their botanical distinctions. The struc- tural difference between them is as follows :—In Dracena there is only a single ovule in each of the three cells of the ovary ; in Cor- dyline there are a great many—eight to fourteen, say the books. Of course in both there is a tendency for the ovules to become abortive without ripening into seeds; but so far as my experience of the Ti Trees goes, there are never less than two or three seeds in a cell, whilst in the Dragon Trees there cannot be more than one, and frequently one or two out of the three cells become obliterated, as is the rule in the Oak or Horse Chestnut. In Dracena the stigma exists in the form of a head lke the button of a fencing-foil, with three little blunt lobes, asin the Lilies. In Cordyline it takes the form of three small hooks like the top of a shepherd’s crook or the handle of a walking-stick, as in the Fritillaries. So much for differences in the actual structure of the flower ; next for habit. In Cordyline the flowers are placed singly on the rachis of the panicle, each sur- rounded by a regular little involucre, formed of the membranous bract that subtends the pedicel on the side farthest from the axis, and inside the pedicel a pair of bracteoles, just like the bract in size MR. J. G. BAKER ON DRACENA AND CORDYLINE. 29 and substance, which are sometimes quite distinct from one another, and sometimes united along their borders. In Dracena the pedicels spring out of the rachis in bundles of two or three, or in some species of many together, without any such regular arrange- ment of bracts and bracteoles as I have just described. The pedicels in Dracena are usually longer than in Cordyline, and the perianth is united through a greater portion of its length, but this does not hold good invariably, and in the shape of the leaves there is very much the same range of variation in both. Dr. Regel adds that Dracena may be distinguished also by its orange-coloured roots and by the absence of runners, but these latter are present im the African D. surculosa. “The number of ovules and seeds, the shape of the stigmas, and the arrangement of the pedicels and bracts are the points on which it is safe to rely, and the two genera were separated by Jussicu when he laid the foundations of the Natural System in 1789, and have been adopted by Robert Brown, End- licher, Meisner, Kunth, Dr. Hooker, and all other writers who have had occasion to deal with them. The geographical distribution of the two genera is not dissimilar. They are both spread through Tropical Asia and North Australia, and are-both entirely absent from Europe and America; but whilst there are several species of Dracena in Tropical Africa there are no Cordylines, and the latter, on the contrary, stretches into New Zealand and Polynesia, where Dracena does not reach. An ex- cellent monograph of all the known species of Dracena has lately been published by Dr. Regel in the ‘‘ Gartenflora,’’ and there is an account by Dr. Hooker of the New Zealand and Australian Cordylines in the volume of the ‘‘ Gardener’s Chronicle ” for 1860, and two later descriptive lists of all the known species and fom have been published by Dr. Karl Koch in the Berlin ‘‘ Wochen- schrift.” I will conclude with a list of forms of Cordyline which within the last few years have been placed in circulation in horticulture as species of Dracena. None of them, so far as I know, have been botanically described, and we shall probably not be far wrong in assuming that most of the names in the following list represent mere forms of Cordyline terminalis, varying in the shape, size, and colouring of the leaf. I need scarcely point out that the distribution of slight varieties of an old well-known plant under new specific names appended to a genus to which they do not belong has a great tendency to cause confusion in the minds both of gardeners and bota- nists; and I hope that in this particular case the Horticultural 30 ROYAL HORTICULTURAL SOCIETY.

Do Flies Eat Pollen? By Atrrep W. Benyert, M.A., B.8e., °F .L28: [Read December 7, 1872.] Ar a meeting of the Scientific Committee during the past season, the question was raised whether Diptera eat pollen, or whether they merely carry it away accidentally when searching for the nectar which is their ordinary food. Having ventured to express the opinion that certain Diptera, and especially some of the Syrphide, do feed upon pollen, I found this was not the view of the entomo- logists present, who expressed disbelief that insects provided only with a proboscis and no mandibles could obtain any food more solid than the juices of plants. In order to decide the question I this autumn captured a number of the Syrphide which on a sunny day swarm on the Composit bed at the Regent’s Park Botanic Gardens, and subjected the contents of their abdomen to examination under the microscope, when I found them in several instances to contain considerable quantities, and in one to be absolutely loaded with pollen-grains, which were easily recognised as belonging to some Compositous plant, probably some one of the species of Aster then abundantly in flower. The flies examined belonged to two species of very different size—Hristalis tenax and Syrphus clypeata. The exact mode in which flies use their proboscis in feeding upon pollen—although apparently unknown to English entomologists— has in fact been accurately described by Dr. Erm. Miller, of Lippstadt, in a discourse delivered to the General Assembly of the MR. A. W. BENNETT ON “‘DO FLIES EAT POLLEN?” 31 Natur-historischen Verein fiir Rheinland und Westphalen in 1869* :— | ‘« As to flies, it has been till now generally admitted that they are exclusively destined to fluid nutriment. But in the summer of 1867 I was somewhat surprised, while observing in my garden an Eristalis tenaxz upon a flower of° Ginothera media, to discover that it was eating the pollen. Resting upon its middle and hind legs, it thrust out its fleshy proboscis like an arm, seized a morsel of pollen with the two valves which terminate the proboscis, and tore it away from tke anther. Since the pollen-grains of Gnothera are tied together by elastic threads, that bit of pollen torn from the anther was attached to others by a band of threads, and the insect, in order to free its mouth from that inconvenient appendage, began to use its fore-legs. Raising both together towards its mouth, it seized between them the cordon of threads, and rapidly rubbing them one against the other, much as we do in washing our hands, succeeded in cutting the threads, and clearing them from its mouth and legs. Then it raised them again and seized the two valves of the proboscis, thoroughly cleaning them of pollen and the threads yet adhering to it; and in about three seconds the work of cleaning was complete. At the same time the valves of the proboscis, by rubbing against each other, had masticated the morsel of pollen, and had conveyed the single granules into the channel of the labium, whence they were pushed into the mouth. It had hardly finished cleaning its proboscis and eating the first mouthful of pollen, when it seized another portion, and repeated each and all the operations I have described. It was so intent upon its meal that I was able to observe it in the closest proximity without its manifesting the slightest fear. “The quantity of pollen which an #y7stalis can devour in this way issurprising. Upon making a section of one and examining the stomach, it appeared very large, and was full of a yellow sub- stance which consisted of hundreds of thousands of pollen-grains. I have had since then many opportunities of observing the eating of pollen, not only in all the species of Hyvstalis, but also in the genera Rhingia, Syrphus, Volucella, and Scatophaga. This chew- ing of pollen alternates with sucking honey if the flowers have any, and I am of opinion that the singular structure of the proboscis of flies cannot be fully explained without taking into account its double function of sucking honey and eating pollen. In the Tipu- * © American Naturalist,” July, 1871, p. 290. o2 ROYAL HORTICULTURAL SOCIETY. larie, and also in those flies which do not cat pollen but live ex- clusively upon juices, for instance Bombylius, the two valves of the proboscis serve no other purpose than to protect and guide the sucking tubes; but in the flies which devour pollen, besides this function, there is also that of grinding the pollen, for which they have special adaptations, for the margins of the two valves at the point of union are transversely dentate with fine parallel bands of chitine. Probably the greater or less distance of these bands in different species is related to the different size of the pollen upon which they feed.” [Additional note, March 10, 1873.] The subject has also recently been investigated by the well- known naturalist, Mr. idward Newinan, whose conelusions on this point are equally at variance with those of the majority of his brother-entomologists. He asserts unhesitatingly (‘‘ Entomologist ”’ for Jan.; 1873, p. 291, and for March, p. 336) that the ordinary food of Hristalis, as well as of many other Diptera, is pollen ; ‘¢ Masses of this and other solid substances being found in their stomachs undissolved and unaltered after passing through the entire length of the leathery and‘extensile promuscis.’”? Whether, how- ever, the pollen-grains are entirely unaltered, or whether their liquid contents or ‘‘ fovilla”’ is extracted for the nourishment of the insect, is a point which cannot at present be considered as decided, and which must form the subject of a future series of observations. In a recent communication to the *‘ Field,’? Mr. Newman thus describes the process, as observed by him, by which the Syrphidee detach and devour the pollen of plants, which it is interesting to compare with the independent observations of Prof. Miiller :— “* Kristalis tenax, pertinax, and sequax are all greedy~ devourers of pollen, and all of them devour it in the same manner. They thrust their proboscis among the florets, separate the two spreading valves with which its extremity is furnished, grasp a cluster of pollen-granules, detach them from the flower, and swallow them. The operation of detaching the pollen-granules is not performed without some skill and exercise of ingenuity, for in many flowers the granules are united together by slender tenacious threads, which must be broken before the granules can be swallowed. This swallowing of the pollen is very obvious to the patient observer; the granules, a few at a time, ascend the leathery proboscis and thence descend into the stomach, which becomes gorged with them, and from which they may be extracted, after the insect is killed, in REPORT OF THE CHISWICK BOARD OF DIRECTION. 30 a perfectly unaltered state. The yellow pollen-granules frequently impart their colour to the abdomen, more especially to its sides and under-surface. After the fly has swallowed a granule or mass of granules, it occupies several seconds in clearing its head from the granules, threads, and other impurities which still adhere to it—a process performed by its first pair of legs in a manner that strongly reminds one of a cat washing its face with its fore-paws.”’ Mr. Newman even goes so far as to suggest—though he does not assert this to be the case—whether these three species of Hristalis are not entirely destitute of the power usually attributed to them of imbibing the liquid honey of flowers. Atall events, in a series of observations extending over two autumns, he has never detected them in the act. The utility of this affection for pollen on the part of these very common and widely-distributed species of Diptera, in promoting the cross-fertilisation rather than the self-fertilisation of the flowers they frequent, is sufficiently obvious. IX. Report of the Chiswick Board of Direction. [Presented February 11, 1873.] Durine the past season the work at Chiswick has been mainly directed towards the perfecting of the arrangements attendant on the alterations in the garden in the previous year. It was then reported that in consequence of timely, though not unusually copious rainfall, the valuable collection of fruit-trees had been re- moved with scarcely any loss. The late gloomy and rainy season was peculiarly favourable to the complete establishment of the transplanted stock, the deficiency of fruit being highly conducive to the same end. Though there has been little opportunity for what may be more strictly considered as scientific investigation, important trials in a horticultural point of view have been carried on with respect to various objects of cultivation. Those on the different varieties of Kales and Peas were made under unusually favourable conditions. Both were very carefully examined, the latter including upwards of 200 reputed varieties, by the Fruit Committee, and the results in either case are recorded in the numbers of the Society’s Journal recently published. In order that no dissatisfaction might arise as to VOL. IV. D 34 ROYAL HORTICULTURAL SOCIETY. results, each sample was marked with a number, the name of the contributor being kept back, and as the decisions were almost, if not quite unanimous they may be regarded as conclusive. To eleven of the newest the Committee awarded First-class Cer- tificates. Amongst the most remarkable of the varieties in the trial were a large number raised from crosses effected by Mr. Laxton, of Stamford. The weather was not equally favourable to trials with flowers, a worse season for Pelargoniums being scarcely conceivable. 400 varieties of Zonal Pelargoniums were planted out. The more deli- cate varieties made no growth, and even the coarser ones did not develope fully their respective merits. Of Phloxes 260 varieties, and of Penstemons 100 varieties were also grown in the flower-beds of the new trial ground, while of Fuchsias 100 varieties were grown in pots. These last indeed were not subject to the continued rain, but they suffered like the other occupants of the conservatories from the continued absence of sunlight. The Floral Committee held three meetings at Chiswick for the examination of these. collections, and awarded 41 Certificates to Pelargoniums, 28 to Phloxes, 21 to Penstemons, and 26 to Fuchsias. Reports on these collections are published in the last numbers of the Society’s Journal. During the past year a large collection of Peaches, Nectarines, Apricots, and Cherries has been procured and planted against the new boundary walls, for the purpose of comparison and determina- tion of the varieties. These have all been trained in the form of single oblique cordons, so as to economise space and to secure as great a number as possible against the walls. Owing to the late spring frosts, which caused such havoc among the fruit crops in the country generally, all out-door fruits, with the exception of Strawberries, were unusually scarce in the garden. The large Orchard House continues very attractive. The trees during the past season were laden with fine highly-developed fruit, and were a subject of study to many of the Fellows of the Society. The Vines in the large conservatory exhibited last year indica- tions of languor, through defective root action. This is doubtless attributable to the borders having become exhausted; these having been renewed, a more vigorous growth and greater pro- duction of fruit may be expected next season. A new plantation of Strawberries has been lately completed. The trial during the next season, for which preparations are being made, will embrace all the varieties of Potatoes which it is possible to collect. REPORT OF THE CHISWICK BOARD OF DIRECTION. 30 Great pains have been taken to get together a collection of such in- teresting hardy Herbaceous plants as may be worthy of general cul- tivation. It isnot within the province of the Society to attempt any- thing like a Botanical collection ; but within certain limits the Board are anxious to do something towards restoring a general taste for beautiful forms other than those gorgeous masses of colour which have become so prevalent, and which at one time, except for the concomitant attraction of Ferns, bade fair to exclude from gardens everything except a few favoured bedding plants, which were re- peated universally, with scarcely any variation. It is desired during the coming season to get together more especially a collection of all the cultivated Asters which can be met with, with a view to a revision of the nomenclature. which appears to be in a very confused state. Any contributions from Fellows for this object will be thankfully received by the Gardener-in-Chief. The re-establishment of the system of meteorological observa- tions has not been effected without difficulty. The fine set of new instruments purchased by the Society from Messrs. Negretti and Zambra were personally conveyed to the Kew Observatory by Prof. Thiselton Dyer. Having been satisfactorily tested, they have been fixed in their proper positions at Chiswick, and the observations have been regularly taken with them since the beginning of July. The thermometer-stand, however, which was made at considerable expense at the recommendation of Mr. Glaisher, does not prove wholly satisfactory, and it may ultimately prove necessary to abandon it for some other arrangement. It will be seen from the following figures that the rainfall at Chiswick of the last six months of 1872 was equal to about two- thirds of the average rainfall of the whole year (23-5 in.) :— Number of Average Days on which Rainfall, Rainfall Rain fell in 1872. of 1872. 44 years, July Ph ae 14 oe 1°94 ite 2°32 August .. he 13 an 1°88 ae 2°41 September. . bos fg ae 1°19 ta 2°50 October .. a 24 ve 4°65 bY 2°63 November .. se 22 iw 3°25 ee 2°10 December .. = 22 . 3°94 ae 1°53 106 A 16°85 a0 13°49 In the period 1826—1869 the whole rainfall of the driest year (1858) was 15°8 in.; in 1864 the whole rainfall was only’16°9 in.

D 2 36 ROYAL HORTICULTURAL SOCIETY. It is hoped during the present year to make some progress with the formation of a herbarium of correctly-named specimens of cultivated Herbaceous plants. This will be exceedingly useful for purposes of reference, especially for naming the living collection. A very important collection of the seeds of Cotton plants sup- plied by Major Trevor Clarke was raised at Chiswick for the International Exhibition, of which it proved to be one of the most interesting and attractive features during a great portion of the period the Exhibition was open to the public. Experiments are about to be made on the practical manurial value of the various products of Major-General Scott’s system of sewage precipitation. The conservatory at South Kensington has been maintained in an exceedingly gay condition throughout the season by means of 14,200 ornamental plants cultivated at Chiswick for that purpose ; while the exterior gardens at South Kensington have been em- bellished by 52,000 bedding plants from the same source. During the year about 9000 flowering plants; 16,000 cuttings of flowering plants; 1200 packets of cuttings of Apples, Pears, Plums, Cherries, Vines, and Figs ; 8000 Strawberry plants ; 60,000 packets of flower seeds; and €0,000 packets of vegetable seeds, have been distributed amongst the Fellows by ballot or otherwise. Large collections of cuttings of fruit-trees have been sent to Aus- tralia, Canada, Natal, New Zealand, and India. Presentations of plants, seeds, &c., have been received from- amongst others: The Royal Gardens, Kew; Dr. Denny; Major Clarke; Messrs. Veitch and Sons; W. Bull; Knight; F. and A.

[Presented February 11, 1873.] Durine the past year I have endeavoured, as far as possible, to carry out regularly the duties assigned to the Professor of Botany in the last Report of the Council. In the months of April, May, and June I delivered a course of six lectures on ‘‘ Flowers and Fruits.” The average attendance at each lecture was about fifty persons. I may perhaps be permitted to remark that it would add considerably to the comfort of the audience if, on future occasions, access could be obtained to the offices with- out the necessity of traversing the Council-room while the lecture is proceeding. I have to thank Messrs. Veitch for the loan of nume- rous plants for purposes of illustration, besides those which I obtained from the Society’s own gardens. During the Birmingham Show a Horticultural Congress was held on the afternoons of the 26th ‘and 27th of June. Introductory addresses were delivered by myself and Mr. Moore, and ten papers were read. The want of time for adequate discussion was, how- ever, felt to be a great drawback to the practical usefulness of the meetings. It appears to me very desirable that, if held at all, the Congress should continue to be under the auspices of the Society, but I am inclined to think that it would be better to confine it to a single evening meeting, at which one or two subjects only should be taken up. The Journal of the Society will for the future be published quarterly, under the joint editorship of the Rev. M. J. Berkeley and myself. Each number will contain, in addition to other matter connected with the scientific work of the society, a brief reswmé of the Chiswick meteorological observations, with respect to which further information will be found in the Report of the Board of Direction. In exchange for the Chiswick meteorological observa- tions the Director of the Meteorological Office has regularly sent to the Society the daily charts placed in the Council-room. . At the commencement of April the Council placed the charge of the Lindley Library in my hands. Having to a considerable extent re-arranged the books, I was able to suggest to the trustees the sale of seventy-six volumes which were either duplicates or un- connected with botanical or horticultural subjects. During the past year 108 volumes have been added, and seventy-nine volumes bound. Access to this library I have found of the greatest possible 38 ‘ROYAL HORTICULTURAL SOCIETY. importance in the performance of my official work, more especially on the show days. On the 18th of July I despatched to the Jardin des Plantes a collection of forty-two species of Orchids from the Society’s collection. These, together with a collection from W. Marshall, Esq., reached Paris in good condition, and during the summer I had the satis- faction of personally seeing the appreciation in which they were held. Besides engaging in a considerable and increasing corre- spondence, I have determined the names of 189 plants sent to me for that purpose. There is one point which I wish in conclusion to take this op- portunity of more especially urging. J amstrongly impressed with the inequality in value of the certificates awarded by the Floral Committee. It appears to me that the enterprise and expense of introducing an important new plant into the country is ordinarily far greater than that involved in producing a new florist’s variety of an old established species. I think, therefore, that the two classes of cultivated plants should receive different forms of certifi- cate. The number of First-class varieties: of the Dahlia, for example, is endless. The result mfst be, I cannot but think, to reduce the value of the First-class Certificate. At any rate it must make such a distinction appear inadequate when a new plant of the importance of say Phalenopsis Schilleriana makes its appearance for the first time at the Society. W. T. THISELTON DYER. XI. On Pteris serrulato-tremula. By THomas Moorz, F.L.S., - Floral Director to the Royal Horticultural Society. Tus very interesting greenhouse evergreen Fern, of which a figure representing the upper portion of a frond forms Plate V., sprang up about a couple of years since in one of the propagating- houses at the Chiswick garden, and is believed to be a hybrid between two well-known species, Pteris serrulata and P. tremula, which are very largely grown there for decorative purposes, on account of their free-growing and elegant character. In the earlier stages of development the fronds were so closely like those of P. serrulata that the plant was looked upon as a slight variation of ~“ MR. BAKER’S CLASSIFIED LIS£ OF ALL KNOWN LILIES. 39 that species; but the successive fronds gradually changed in character until they showed a near resemblance to P. tremula, differing mainly in the more elongated outline of the frond. In the intermediate stages the fronds assumed a more intermediate character. The habit of the plant is elegantly spreading, the erecto- patent fronds being upwards of 24 feet in height, including a stipe of 6 or 8 inches, the outline of the leafy portion being elon- gate-triangular, with a tendency to furcation in the rachides and at the tips of the pinne. The stipes are pale chestnut brown, as in P. tremula, and the fronds have the same palish green colour which occurs in that species, from which this novelty differs in its narrower fronds, and the numerous elongated caudate apices which occur both on the pinne and on the more compound of the pinnules, and are often as much as 3 incheslong. The following description embodies its chief peculiarities :— Fronds tripinnate (in the few lower pinne), 24—38 feet high, elongate-deltoid, pale green ; lower pinne triangular, bipinnate, the segments pinnatifid at the base and terminating in a long caudate apex, the intermediate pinnules sessile, pinnatifid at the base with linear-oblong segments and acaudate terminal one, the apex pin- natifid with linear-oblong decurrent lobes and a terminal caudate one; upper pinne less compound, but caudate, and having the basal pinnules also caudate, the uppermost merging into linear pinnatifid or linear entire segments, the apex being caudate; sori continuous, with linear entire indusia; veins once or twice forked, free ; stipes and rachis chestnut brown, furrowed in front, smooth and glossy.

MALCOLM DUNN ON PHYLLOXERA VASTATRIX. 49 XIII. Note on Phylloxera vastatriz. By Mr. Matcotm Dunn. [Mr. Dunn contributed last year (vol. iii., pp. 81—86) an account. of the plan he pursued at Powerscourt for extirpating the Phylloxera. The following remarks were addressed to a correspondent, and are extracted from ‘“ The Gardener ” of February last, pp. 63—64.] I am very glad to hear that you have decided upon burning all your infected Vines and removing all the borders, and at the same time thoroughly cleansing every part of the houses, making sure that not a vestige of the insidious pest is left. By doing so you will have much more confidence that you have thoroughly stamped it out. Had I to deal with it again I would certainly deal with it in the same way, unless I had very special reasons for cleaning and saving the Vines, though I hope I may never have the task of dealing with it again. One attack from so dreadful a scourge is quite enough in a lifetime. By taking proper means, I have not the slightest doubt but that the very worst infected vineries can be effectually cleansed ; for with all my three years’ experience of it, I never found that the insect lived more than forty-eight hours when isolated from the Vine. Indeed, in all the numerous experi- ments I tried in placing it on other plants than the Vine tribe, it never lived forty-eight hours; but on the Vine it prospered and increased with amazing rapidity. I triedit on American varieties, such as Concord, Isabella, Sombruska, and the result was the same. There were Camellias, Azaleas, Cacti, Palms, Fuchsias, Pelar- goniums, &¢c., with various sorts of bedding-plants, in the vineries, and although their foliage in some cases was put amongst the infected Vine-leaves and their roots, in other cases running through their pots into the border amongst the infected Vine-roots, I never found an insect feeding on any plant except the Vine, and only in a very few instances did I find them trespassing on any other plant ; and when I did find them, I usually took them to my office and placed them carefully under glasses, where I could watch them, and their life was always cut short within forty-eight hours. I tried to get it established on various vegetables and fruit-trees, but it would not feed nor live on them. There were Figs in the vineries, and the pest never touched them. Consequently my experience coincides with your own that the Phylloxera will not deposit its eggs nor live in any other plant but the Vine. With regard to the eggs, I have kept roots and leaves with eggs and live insects all through the winter ; but as soon as the,sap of the leaves and roots were exhausted, the eggs became shrivelled and never produced live insects. I took pieces of roots infested VOL. IV. E 50 ROYAL HORTICULTURAL SOCIETY. with the insect and placed them in the soil into which clean Vines were potted, and in fourteen days the roots of the pot-Vine were swarming with insects. Before I became sufficiently cognisant of the habits of the little devourer, the galls quite covered the under sides of hundreds of the young leaves, and the young wood was perfectly riddled with holes or punctures into which they had burrowed, feeding on the sap and depositing their eggs. I could compare their operations on the young wood to nothing but small-pox, so thick did they puncture it. The two following years I did not allow it to get ahead much, for I picked off and burned the infected leaves. I had the insect nearly as bad in the outside border as inside, but the borders were’ covered with leaves and strong wooden shutters from September to May, and were consequently compara- tively dry and warm. There can be no doubt they thrive best in dry warm quarters, and they could be easily drowned, but the difficulty les in getting at them. The small roots were eaten up. When lifting the Vines, I never found any larger than a thick quill, and the strong roots were infested up to the collars of the Vines. XIV. On the Cultivation of the Olive near Ventimiglia. By Mr. L. Winter. [The following information was very kindly obtained by Mr Daniel Hanbury, F.R.S., for transmission to Natal, by a Fellow of the Society, It is also printed in the ‘‘ Pharmaceutical Journal ” for September 7, 1872.] As you wish for a little information on the propagation of the Olive in this part of Italy, I have drawn up a few remarks which, though aot containing much that is new, may yet serve to complete or to. confirm your own observations. The different kinds of Olive-tree we have in this country may “be classed under three divisions :— 1. Olivastro, the Wild Olive, Olea europaea, L., grows quite spontaneous, reproducing itself by seeds and suckers; leaves on young trees small and oblong—on older trees a little larger and lanceolate; branches sometimes spiny; fruit small, oblong, and very bitter. This kind may be regarded as the parent of all the varieties. . MR. L. WINTER ON THE CULTIVATION OF TIE OLIVE. 51 2. Varieties reproducing themselves truly by seed, but not so freely as the Olivastro, and having the fruit less bitter. Under this head may be placed the following :— | a. Pignuole.—Branches greyish ; leaves lanceolate, acute ; fruits when ripe almost round, affordirg an oil of rather strong flavour. There are hundreds of these trees on the Capo Martino, near Mentone, quite wild. 8. Columbaire (Genoese dialect).—Branches brownish; leaves varying in shape, but mostly obtuse; fruit large, somewhat pointed. y- Spagnuole.—Fruit more elongated than the . preceding. These forms, «. 8. y-, vary more or less ¢néer se. 8. Varieties not reproducing themselves truly by seed, but returning to the Olivastro. That these varieties degenerate when propagated by seed is the general assertion among the people here ; but regular experiments have never, I think, been carried on, for raising the plant by seed is not advantageous, suckers being of more rapid growth. In this division I would place two varieties, viz. :— «, Nilane.—Fruit large, oblong. This occurs in abundance as far west as Cannes, whence along the whole French coast of the Mediterranean another Olive with still larger fruit is cultivated 8B, Punginaire.—This is another variety which we have in this country. It has long Willow-like leaves, and produces a very large pointed fruit, chiefly preferred for salting. The propagation of Olive-trees belonging to this third division is effected by cleft-grafting on the stem of the Olivastro at about six inches above the ground. When the scion has taken, earth is heaped around it, so as to stimulate it to shoot out roots. After three or four years the little tree begins to fruit, and arrived at an age of about twenty to twenty-five years, the roots which have been thrown out by the graft send up suckers, any which come from those of the parent Oliwastro being of course extirpated. These suckers, when about two years old, will be strong enough to bear separation from the parent root and to be planted as independent trees. Such young trees fruit in three to five years after planting. When a sucker is thrown out from a large naked: root, it may be surrounded by a heap of earth, into which it will strike roots, and in due time may be separated as already explained. The quality of the oil obtained from the cultivated Olive very ees ROYAL HORTICULTURAL SOCIETY. much depends on the degree of maturity of the fruit. The riper the latter the better will be the oil it yields. Near Marseilles the Olives are gathered in October and Novem- ber, while they are still unripe, and the oil is consequently of very inferior quality. This plan of anticipating the crop is adopted on account of the cold mzstral, which spoils the Olives, sometimes completely freezing them and rendering them nearly worthless for oil. To make the trees thicker in foliage, and thus capable of affording a natural shelter to their fruits, the peasants prune the tops every year after the gathering. In this district of Italy com- paratively little pruning is needed, the trees on many properties being allowed to grow quite au naturel. About La Mortola and the adjoining district of Latte, as well as on all the lower slopes of the Riviera, the Olives are frequently attacked in the month of July by an insect called moschino, which lays its eggs in the berry. The caterpillar developes itself in August, finding its nourishment in the pulp of the fruit. Olives thus infested drop from the trees while not yet fully ripe—that is, in October, November, and December. On the mountains at some distance from the sea, the Olives are scarcely at all affected by these insects; the fruits in consequence attain their perfect maturity, the crop being gathered between December and May. The oil yielded by such Olives is very clear and of superior flavour, and it commands a high price. In proof of this latter fact, I may remark that the value of the oil produced at Latte contrasted with that of the mountain village of San Michele at the head of the valley is ordinarily as three to four, sometimes even as two to three. XV. Rainfall at Medellin, New Grenada, South America. Lat. 6° 2'N., Longitude 75° 49’ W. Communicated by Mr. Witson W. Saunpgrs, F.R.S. As Medellin is a locality from which many plants of horticul- tural interest have been introduced, the following brief record of its rainfall will not fail to be of some value as an indication of the character of the climate. While rain falls during every month of the year, the months from December to March appear to be the driest season. It is noticeable, however, that July and August had less than half the rainfall in 1871 that they had in 1870. METEOROLOGICAL OBSERVATIONS AT CHISWICK. 03 Year 1870. Year 1871. Months.

XVI. Meteorological Observations taken at the Royal Horticul- tural Society’s Gardens, Chiswick by W. Srinxs. Reduced by R. Srracuan, Meteorological Office. Tux readings of the barometers and thermometers are all corrected for instrumental errors (which have been ascertained at the Kew Observatory), and those of the barometer are reduced to the tem- perature of 32° Fah., and to mean sea-level. The rain gauge is 25 feet above sea-level. The temperature of evaporation is regularly observed, but is not given here. It has been considered preferable to give the dew- point, which has been calculated from this observation by means of Glaisher’s factors. The figures denoting the estimated force of the wind signify as follows :—1, light air; 2, light breeze; 8, gentle breeze; 4, mode- rate breeze ; 5, fresh breeze ; 6, strong breeze; 7, moderate gale; 8, fresh gale; 9, strong gale; 10, whole gale; 11, storm; 12, hurricane. The notations of weather are, for brevity, expressed by letters which signify as follows :—b, blue sky ; c, detached clouds ; 0, over- east; f, fog; m, mist; r, rain; h, hail; s, snow; d, drizzle ; p, passing showers; q, squalls; t, thunder; 1, lightning. A letter repeated denotes intensity. : *s1voA TourIoOy Jo UWVIUT 9Y} FO SS9OXA UT [[BIMIVI OY) PUL ‘“BSVIIAG 9} OANGV SVA 9INGBIBdUIOY OT} ‘OSBIOAB OY} MOTEQ SBA OINssaId oreydsouys oy} Arenuve Suma A AP MEET A 5 iia AM tis Et a TAP Te ge rec S De ROYAL HORTICULTURAL SOCIETY. 54 —_ |; LG-3 , 9-1 | AA.gts G-FE G.L8 1-LF 2-88 8-1F 1. 8¢2-6% | suvozy 0 oe See ih Z aS ¢-g8 0-F8 098 Z-3E 0-2¢ | §e0.08 1g o 0 0 si j AN 0-08 0-28 ¢ 9g €-08 ¢.¢g €10-08 0g o 0 o = T "ag 0-83 0:62 0-98 0-92 G.28 260-08 63 q 9q wo q 5 I "aS 0.9% 0 62 0.0% 0-2 ¢.1g 880-08 8Z fe) 3} 0 J #2 if WN C.eZ ¢ 92 0-8 ¢.0¢ ¢.0g 811-02 1% q 09 s) ea g "aS G.0% ¢.9Z 0-18 0-¢¢ C.68 Zh6-63 9 q Ff FJ ; I MNN C.4Z 0.¢ 0' FF ¢-8z ¢.8% 886-62 4 oq oq fe) 20-0 4 ANN 0.63 0-¢¢ C.F 3-8e G.0F OFF-6Z 7G fe) q q Z1-0 z M C.1Z C.08 G.F 0-¢¢ ¢.¢g £89.62 &% doq a) oq . rd AS Liz C.18 0 GF BLE G.68 211.8% ZZ q q q 60-0 I MNM C.1Z @.08 ¢.0F F-0Z a 026-8 1Z ol os) ros) me z AAS G-18 0-62 C.F 0.8% 0-FS ZEE-8T 03 10 0 0 60-0 z AASS 0.

Report on Plants Grown for Trial at Chiswick, 1873. By Tuomas Moors, F.L.S., Floral Director R.H.S. Tue subjects specially examined by the Floral Committee during the summer of 1873, for the purpose of ascertaining the merits of the novelties submitted for trial, were Pelargoniums, Fuchsias, Pentstemons, and Phloxes. The Pelargoniums, with the exception of the salmon-coloured and white varieties (which according to the previous instructions of the Committee were grown in pots), were tried as bedding plants, the Fuchsias as decorative pot-plants, and the Pentstemons and Phloxes as border flowers. As in former Reports the mark *** indicates the highest quality, and the award of these marks is thus regarded as equivalent to that of a First- class Certificate. It should also be explained that the names of persons given in parentheses, after the name of the variety, indicate the donors of the plants, who are not necessarily, or in all cases, the raisers. PELARGONIUMS AS Brepprne Puanrs. Golden-variegated Zonals (Golden Tricolors). Of the older sorts Amy Richards, Louisa Smith, and Iaecbeth proved to be varieties of first-class merit, and to be the three most distinct of the stronger-growing sorts, whilst Florence was the best in the dwarfer group. The following sorts were tried for the first time as bedders :— Beautiful for Ever (Kk. G. Henderson) ***. Bright shining foliage, with broad very bright red zone, and very little green; a very good variety. Col. Loyd Lindsay (KH. G. Henderson) ***. Leaves flat, rounded ; zone bright rosy-red, of moderate breadth, with even golden margin; moderately vigorous. Countess of Hnmskillen (K. G. Henderson) ***. Leaves large, the centre greyish; the zone rosy-red, irregularly vandyked, with broad edge of creamy yellow ; habit vigorous. Madonna (HK. G. Henderson) ***. Leaves with broad zone of deep bronzy red, and narrow edge of yellow ; bold and good. Oriental (EK. G. Henderson) ***. Flat foliage, with broad zone of very bright red ; a moderate grower, and very effective. Peter Grieve (EK. G. Henderson) ***, Leaves large, flat, with fiery orange-red zone, and broadish margin of yellow ; telling. Vol. IV. F 58 ROYAL HORTICULTURAL SOCIETY. Princess Lowise (K. G. Henderson) ***, Leaves large, flat, with medium edge of yellow, and broad zone of orange-red; effective. Beautiful Star (E. G. Henderson). Leaves broad, flat, with broad zone of deep crimson-red. Countess of Ashburnham (EK. G. Henderson). Leaves large, with rather narrow zone; tolerably effective ; strong vigorous habit. Countess of Flanders (W. Paul). Leaves flat, shining, with narrow golden margin, and very broad and bright-coloured zone ; mode- rate grower; a new variety, and first-rate in quality. Howarth Aston (E. G. Henderson). Leaves even, with the colours clearly defined; zone broad, very bright red; a really fine variety of moderate growth. Reindeer (K. G. Henderson). Leaves small, uneven; zone narrow, but bright and telling ; moderate grower. W. E. Gladstone (K. G. Henderson). Leaves broad; very bright zone, tolerably even ; a good grower, and effective. Zodiac variegata (Webster). Strong-growing variety, with bright colours; the zone narrow for the size of the plant. Many other sorts were received and planted, but being sent in late, they did not make satisfactory growth, and are reserved for another season. The following were discarded as bedding sorts :—Achievement, Allan-a-dale, Andalusia, Antagonist, Oartha- gena, Chimborazo, Coronet, Crown Jewel, Defiance, Donna Maria, Estelle, Hong Kong, Jetty Lacy, Julia, Lucretia Borgia, Mary Hadwin, Miss Batters, Mrs. Dunnett, Oxonian, Queen of Hearts, Queen of Tricolors, Queen Victoria, Ruby King, Saragossa, Shadow Dance, Solfaterre, Sparkler, Starlight, Zodiac variegata. Silver-variegated Zonals (Siiver Tricolors). Circassian Beauty (Hodgson) ***, Leaves small, with very bright pink zone; free and good; covers tolerably well, being of close growth. Fair Rosamond (KE. G. Henderson) ***. Leaves well developed, and of good colour. Lass 0 Gowrie (K. G. Henderson) ***, Leaves of medium size, rather crumpled, with very broad and bright zone, and creamy- white edge ; very effective. Fascination (EK. G. Henderson). Leaves large, flat, with broad cream-coloured edge, and narrow bright red zone ; distinct. and good both in habit and quality. The following varieties of this group were discarded as bedding REPORT ON PLANTS GROWN FOR TRIAL AT CHISWICK, 1873. 59 plants:—Baron Ricasoli, Caroline Longfield, Clorinda, Emma Chater, Fascination, Felicity, Landseer, Mabel Morris, Mayflower, Mrs. Masters, Miss Burdett-Coutts, Miss Farren, Mysterious Night, Pet of the Flock, Startler. Silver-margined. Among the older sorts, Albion’s Cliffs was considered the best amongst the larger and stronger-growing varieties; and Flower of Spring the best of the dwarf compact-growing creamy-edged sorts. Miss Kingsbury and Silver Chain were also noted as varieties of the first order, the former with-cerise-scarlet and the latter with rosy-tinted flowers. The following were grown for the first time :— Golden Brilhkantissima (H. Park) ***. A form of the old Brillant, of compact growth, with the leaves irregularly edged with yellow and creamy-white ; flowers very freely produced, of a brilliant orange-scarlet ; remarkable for its mixed gold and silver varie- gation. Laura (Bland) ***, Inthe way of Albion’s Cliffs, but more erect ; . strong grower and rather coarse ; leaves with brownish-red zone and cream-coloured margin; bears large trusses of pale scarlet flowers. In this group White Lady and Waltham Bride, both dwarf sorts, were retained for their white flowers; while the following were discarded :—Alma, Brilliant, Maitre d’ Hotel, Mrs. Lenox, Mountain of Snow, Pearl, Princess Alexandra, Snowflake, Variegated Stella. ° Golden-leaved. In this section the Committee decided that both Creed’s Seedling and Crystal Palace Gem retained the high character they had already received. The former was subsequently noted as the best of the purely golden-leaved sorts. The Crystal Palace Gem is of spreading habit, and its golden-tinted leaves have a central green patch ; it is in the way of Cloth of Gold, but smoother. Bronze Zonals. ‘A very useful group for bedding purposes, but amongst the varieties of which there is necessarily great similarity. Among the good sorts of older date, the Committee specially approved Waréchal MacMahon and Black Douglas, and Rev. C. C. Peach was noted as of strong and rather coarse habit. The novelties included the following :— Golden Harry Hreover (EK. G. Henderson) ***,- Dwarf spreading | F 2 60 ROYAL HORTICURTURAL SOCIETY. habit, with small cupped foliage of a bright greenish-yellow, with narrow dark zone; very free and good; flowers pale scarlet.

Reid, Northern Star, Patty, Plutus, Rev. F. Radelyffe, Royalty, St. John’s Wood Star, Sybil, W. R. Morris. Pink-flowered. Several new varieties of this section were tried, of which the following were approved :— Amaranth (Pearson) ***. Free habit; leaves green; flowers deep rosy-pink, almost magenta, medium-sized ; large trusses on very long stalks. Bella (Carter) ***. Leaves green; flowers bright rose-pink, with white blotch on upper petals ; very pleasing and effective. Cleopatra (Barrett) ***. Free spreading habit, and free-flowering ; leaves green; flowers bright rose-pink, self-coloured, on long stalks, abundant. Evans’ Seedling (Evans) ***, Dwarf compact habit, with zoned REPORT ON PLANTS GROWN FOR TRIAL AT CHISWICK, 1873. 61 leaves; in the way of Welbeck Nosegay, but of closer and smaller growth; flowers bright rose-pink, with white blotch on upper petals; very free bloomer, and very bright-looking.

Welbeck Nosegay (Tillery) ***. Compact free-growing habit; leaves dark-zoned, slightly cupped; flowers abundant, large, bright deep rosy-pink, with white blotch on the upper petals ; good. The following were discarded for bedding purposes :—Bronze- pink Nosegay, Cannell’s Pink, Caroline, Christine Nosegay, Delight, Fried Zehnbauer, Master Christine, Memnon, Urs. Lowe, Penelope, Pink Stella, Progress, Rose Bradwardine, Rose Peach, Rose Rendatler, Surpasse Beauté du Suresnes, Surpasse Christine. Scarlet and cerrse-flowered, &e.

Forest Hill Nosegay (Downie & Co.) see A most exquisite variety, of free dwarfish compact habit, with the leaves lobed and faintly zonate; flowers abundant in large trusses, rosy- salmon, paler down the centre of the petals. Of other sorts which were considered as meritorious, the fol- lowing deserve to be particularly mentioned :— Warrior, Punch, Excellent, - Vesuvius, Jean Sisley, Lucius, Bayard, Soleil, and Waltham Seedling, all well-known varieties, were regarded as standard sorts of their respective colours and habits. A few others which appeared good may he briefly noticed :— 62 - ROYAL HORTICULTURAL SOCIETY. Grand Duke (G. Smith). Of vigorous habit, with faintly-zoned leaves, and flowers of a light scarlet colour. H. M. Stanley (George). Good. Mercy Grogan (EK. G. Henderson).

Stanstead Rival (Downie & Co.). Of moderately vigorous spreading habit, leaves faintly zoned, flowers rich rosy-scarlet. Wellington (Denny). Good; bold habit, and fine flowers. The number of high-coloured Bedding Pelargoniums has now become so overwhelming that the Committee was led to give its attention to the expurgation of varieties which in its opinion were not equal to others of similar character. The result of the scrutiny was, that the following sorts were struck out of the list of sorts to be cultivated at Chiswick. It is at the same time to be noted that many good varieties will be found amongst those thus set aside, simply because the lists are overcrowded:— Acquisition, Alfred, Amabilis, Archbishop of Paris, Ascendant, Atalanta.

This group, distinguished by the marbled-green of its leaf- blades, and the pale stripings of its stems and flower-stalks, has received an addition of some merit, namely :— Kate Creed (Creed). A free blooming variety of good quality, the leaves marked, in addition to the marbling, with avery dark zone varied in hue, and the flowers being of a light reddish- scarlet. ; From this group Hotspur and Zodiac were thrown out. Lvy-leaved. About a dozen varieties of this group were bedded out with but partial success. Peltatum elegans was very pretty, with deep rosy- lilac flowers of good form. Duke of Edinburgh and Ariosta were the same or indistinguishable. Argus was of vigorous habit, and had dark zoned leaves and rose-coloured flowers. Dolly Varden had the golden-green leaves marked with a bronzy zone. PrLarGconiums As Por Prants. It having been found, after several years’ experience, that the Pelargoniums of the salmon-coloured class especially, were not adapted for bedding purposes, while they were known to be ex- ceedingly ornamental as pot plants, the Floral Committee decided last year not to grow them and the allied kinds again in the open beds, but to institute a trial under glass. This was accordingly done, and with the results indicated below, the whites and the ocellate varieties—those, that is, with pale colours spotted near the centre or eye—being also included in the trial. Marks of merit were awarded to but one variety, which proved still more beautiful as a pot plant than it had as a bedder, namely :-—_ 64 ROYAL HORTICULTURAL SOCIETY. Forest Hill Nosegay (Downie & Co.) #**. Remarkably free in growth, without the least coarseness ; leaves lobed and slightly zonate ; flowers very freely produced in large trusses, of a bright orange-tinted salmon shading off, the centre of the petals being paler, with a bluish flush ; very handsome. The following annotated sorts were selected as the best of the different shades of colour, the notes being made from the plants as grown under glass. The varieties considered to be the best of the respective shades of colour were selected to be retained in cultiva- tion, and the rest were discarded :— Salmon-coloured and ocellate sorts.

Many of the varieties forming the trial collection were received last year, but so late or in so weak a condition that they were not fairly represented at the time the Committee made its exami- nation. They were accordingly grown again this year from young plants, and the following notes may be regarded as supplementary to those published last year ( Journ., N.S., vol. iii., p. ex.—exviii.).

Some of the varieties of this fine border flower did not come into flower till late in the season, after the visits of the Committee had been made.

Barron, Gardener-in-Chief, and Secretary to the Fruit Committee. Tue Fruit and Vegetable Committee having decided upon testing the numerous varieties of Potatoes that are in cultivation, and ascertaining their various characteristics, I made application among the growers, and succeeded in obtaining no less than what purported to be 271 distinct varieties. These, with a few exceptions, were planted on the 24th of March, and the sets used were good medium-sized whole tubers, when these could be obtained; but in some instances they were small, and then the produce was much inferior. The ground was well dug in the autumn of the previous year, but not manured, this having been done for the crop of Peas which had just been removed. The tubers were planted in lines 3 feet apart and 20 inches between each tuber. The plants came ° up regularly, with a strong growth; and on the 20th of May they were attacked by a strong frost, which cut them very much, some of them being as muchas 6 inches above the ground. They soon, however, recovered and grew luxuriantly, being subjected to the usual mode of cultivation, by hoeing and earthing up. REPORT ON POTATOES GROWN IN 1873 AT CHISWICK. 1a On the 29th of July the disease first made its appearance by attacking the variety called Golden Gem, spreading in a few days with great rapidity to Lapstone, Fortyfold, Red Emperor, nearly all the American kinds, and the Regent class, The haulm of all these sorts was soon destroyed; and of the tubers, those of Regents suffered most severely, about nine-tenths being diseased, and of some kinds, although there was an excellent crop, scarcely a sound tuber remained. There was no variety that was not more or less diseased, those escaping with the least injury being the very early and the very late kinds. During the growing season the collection was examined five times by the Committee, and the first result arising from the experiment has been to reduce the 271 varieties to 115; and this number may be still further reduced by rejecting those that are inferior and worthless. The following is a list of donors who furnished the tubers for the experiment :— Messrs. Bell & Thorpe, Stratford-on-Avon. Mr. Thomas Benson, Petersham. Mr. George Biggs, Larkhall, Bath. Messrs. B.

XXIII. Meteorological Observations taken at the Royal Horticul- tural Society’s Gardens, Chiswick, by W. Srryxs. Reduced by R. Srracnan, Meteorological Office. Tue readings of the barometer and thermometer are all corrected _ for instrumental errors (which have been ascertained at the Kew Observatory), and those of the barometer are reduced to the tem- perature of 32° Fah., and to mean sea-level. The rain gauge is 25 feet above sea-level. The temperature of evaporation is regularly observed, but is not - given here. It has been considered preferable to give the dew- point, which has been calculated from this observation by means * Glaisher’s factors. The figures denoting the estimated force of the wind signify as follows:—1, light air; 2, light breeze; 3, gentle breeze; 4, mode- rate breeze; 5, fresh breeze; 6, strong breeze; 7, moderate gale ; 8, fresh gale; 9, strong gale; 10, whole gale; 11, storm; 12, hurricane. The notations of weather are, for brevity, expressed by letters, which signify as follows:—b, blue sky ; c, detached clouds ; 0, over- cast; f, fog; m, mist; r, rain; h, hail; s, snow; d, drizzle; p, passing showers; q, squalls; t, thunder; 1, lightning. A letter repeated denotes intensity. [A reduction of these observations has been published by Mr. Glaisher in the Registrar-General’s Report, but the results given by him are different, probably owing to the corrections not being applied to each observation, but to the monthly means.—Eps. | : | “AUQUBND VIBIOAB 044 J[VY ATWO SBA [BIULL oYy pu ‘[ensn uvyy y410u oy ULOAZ A[JUONHITF 9LOUL 9IOM SPUIAM O44 ‘g1woA TOUIIOF JO SoSBIGAG 9YY YIM AL.LvoU puodset100 oInyvIeduIeY pus atussetd ay, de Sigh aE Se eS eg ln es ae or cg ee peer nee Cl Re ee ee ee eee eee ee 121 fee eae = 99:0 | 6T |X OLN, THE | O-TOT 8-28 6-96 ¢-0h 1-8 910-0g | suvoy Oo” 0) ) ss > | MNM | 0-08 ¢-80T ¢-FE TLE GH | Sze 06T-08 0g 0 0 do 2 ANN GTP 0-611 0-¢F FG vbP 1g T20-0€ 63s" soq ) 0) 20:0 ‘4 MN 0-18 6-66 0-98 $-6P L-OF 0 67 991-08 82 tj q do | 10 oe ¢ | MNN] 0-18 0-26 G-78 9-0¢ OFF G-8h 26-62 LZ o ) ° a) 20-0 7 ANN 0:83 O-TTT G28 P08 0-@8 ag 082-08 9% E q sho 5) se > ANN 0-82 O-¢TT 0-62 PTS 9-88 GCP SFT-08 GZ iz q sto | 9 q 90-0 g ANG 0-92 @-FIT 0-18 0-19 PE G-Oh 986-62 VG = 0 0 oq oh ¥ N 0:28 0-211 G-F§ 0-29 9-88 CBF CE6-6Z 8% o 0 0 0 - z ANN 0-88 0-01T 0-28 P29 Z-0F ¢-8h 0-08 3z g q q 90 S Dee SOCIETY.

PXTRACTS FROM PROCEEDINGS. 1x Apri 3, 1872. « : FLORAL COMMITTEE. First-class Certificates were given to Messrs. Veitch for Oxcr- dium Crasus ; to Mr. Bull for Zalacca edulis and Dracena metallica ; and to Messrs F. and A. Smith for Azalea, Beauty of Surrey, a superior white. A Cultural Commendation was given for Masde- vallia Lindeni to Mr. J. Linden, who also sent Vriesia corallina and Zillandsia Lindent vera. Mr. Ware sent a superb variety of Iris wberica, while a new Oncidium came from the Society’s collection. SPRING SHOW. - Prizes for Odontoglossums were awarded to Mr. J. Ward, gar- dener to F. G. Wilkins, Esq., Mr. Bull, and Mr. J. Linden ; for Cyclamens, to Mr. Goddard, gardener to H. Little, Esq., and Mr. R. Clarke; for Cinerarias, to Mr. R. Marcham, gardener to E. Oates, Esq., Messrs. Dobson and Sons, and Mr. James, gardener to F. W. Watson, Esq. Mr. Baxter, gardener to C. Kieser, Esq., was the only exhibitor of Amaryllis, and also sent some remark- able seedlings. One of the most interesting features of the Show was the fine group of Clematis from Mr. Charles Noble, while Roses and Orchids were well represented, and three boxes of terrestrial Orchids came from the Comte de Paris. FRUIT COMMITTEE. Cultural Commendations were awarded to Dr. Moore, of Glasnevin, for a fruit of the Chocolate Plant ; to Mr. C. Baldwin, gardener to B. Drew, I'sq., for six very handsome Cucumbers ; and to Mr. Woodham, gardener to H. D. Pochin, Esq., for Keens’ Seedling Strawberries. A First-class Certificate was given to M. A. de Biseau d’Hauteville for a seedling Pear named Beurré de VOL. Iv. b x ROYAL HORTICULTURAL SOCIETY. Biseau. Messrs. Stuart and Mein sent splendid specimens, blanched under boxes or Seakale pots, of their improved Dandelion, which ought to be more cultivated for spring salads. Two bunches of Lady Downe’s Grapes, cut March 30, were not remarkable in point of flavour. Mr. Dodds, of Ashton Court, sent a simple contrivance | for preserving cut Grapes. SCIENTIFIC COMMITTEE. J. H. Girsert, Ph.D., F.R.S., in the Chair. The Chairman made a communication with respect to the Coorongite, or Australian Caoutchouc. Like Elaterite, it is probably a mineral in admixture with an oxidised substance. Considerable difference in the ultimate composition of different specimens may therefore be expected. Dr. Masters described a flower of a Fuchsia in which there was : petalody of the stamens ; and the ovary, from arrest of development, ; was superior instead of inferior. Professor Thiselton Dyer read a translation of a paper by Bous- singatul, ‘“‘On the Production of Honey-Dew”’ (see Journ. N.S., vol. iv., pp. 1—7). Prof. Thiselton Dyer read an extract from a letter from G. Gul- liver, Esq. F.R.S., to the effect that succulent plants, contrary to what might perhaps have been supposed, are not more prone to the production of raphides than other plants. He had in vain examined our succulent seaside plants for raphides. He had looked for them in Chenopodiaceae, Brassicacea, and Crithmum. GENERAL MEETING. J. RussELL REEVES, Esq., F.R.S., in the Chair. Mr. Marshall commented on a distinet form of Odontoglossum Andersonianum, remarking that these hybrids had not been named botanically according to their various peculiarities, as there were more hybrids of the same origin. Professor Thiselton Dyer directed attention to some flowering branches of fruit-trees from Chiswick, to show the serious” effects of the frost of the previous week. The interesting point was the effect produced when the flowers were in EXTRACTS FROM PROCEEDINGS. xi bud; for, though they subsequently opened, the carpels were killed. In Pears especially, not only were the carpels blackened, but also the anthers and the dise on which they were inserted. | Aprit 17, 1872. FLORAL COMMITTEE. A Silver Flora Medal was awarded to O. O. Wrigley, Esq., for a plant of Odontoglossum Phalenopsis having nearly seventy flowers fully expanded. First-class Certificates were given to Messrs. Ivery for the dwarf Hedera Helix conglomerata, for Polystichum angulare confluens variegatum, and P. a. proliferum Henleye; to Messrs. Veitch for Croton lacteum ; to Mr. B. S. Williams for Rhopala elegan- tissima, Hort. ; to Messrs. Rollisson for Erica Neitneriana ; and to - M. Louis van Houtte for Azalea indica-J. G. Veitch, S. Rucker, and Marie van Houtte. A Second-class was also given for another variety, Comtesse Eugénie de Kerchove. A Cultural Commen- dation was given to Mr. J. Linden for several Odontoglossums. AZALEA AND AURICULA SHOW. Messrs. Lane were first for Azaleas, and Mr. Turner second. Messrs. Lane were alone with forced Rhododendrons in pots and cut trusses. Messrs. Turner were first for Auriculas, and Mr. James, gardener to W. F. Watson, Esq., second. In the Amateur Class the Rev. H. H. Dombrain was first, and Mr. James second. Mr. Turner sent the best Alpine or Fancy Auriculas, Mr. James _ second, and Mr. Goddard third. The Metropolitan Floral Society’s Prizes were awarded to the Rev. H. H. Dombrain, Mr. James, and Mr. Goddard for the six best Show Auriculas. The best green-edged were from Mr. Turner, the Rev. H. H. Dombrain, and Mr. James, who, in the same order, exhibited in the grey-edged class. Mr. Turner was first for a white-edged variety, Mr. Dombrain and Mr. James following. The best self was Spalding’s Metropolitan from Mr. Dombrain, 52 xii ROYAL PORTICULTURAL SOCIETY. Campbell’s Pizarro from Mr. Turner second. Mr. James and Mr. H. Hooper staged the best Show Pansies, and Mr. Ware sent the best collection of hardy spring flowers. A Cultural Commendation was given to Mr. G. Bland, gardener to the Earl of Kilmorey, for Anthurium Scherzerianum with fifteen spathes. FRUIT COMMITTEE. A Cultural Commendation was given to J. B. Fernyhough, Esq., for a seedling plant of the Avocado Pear (Persea gratissima), grown in an ordinary Hyacinth-glass filled with water. It was raised from a seed taken from the fruit exhibited the previous September. SCIENTIFIC COMMITTEE. Anprew Morray, Esq., F.L.S., in the Chair. Dr. Welwitsch made a communication on some ornamental plants from Angola which it was desirable to introduce into horticulture, and exhibited specimens. A new species of Maranta was remark- able for its unsymmetrical leaves, elliptical on one side, oblong on the other, and white beneath, except a marginal band on the elliptical side. A scandent species of Phrynium was a remarkable exception to the scitamineous habit; its fruit also was curiously three-sided. It was suggested that this was a plant which, like some Indian species of Combretum and an Eguisetum, climbs when it gets an opportunity. A variety of Dusa sapientum possessed foliage of a blood-red colour. Dr. Welwitsch also exhibited seeds of I. ventricosa, Welw., a near ally of Jf. Ensete. ‘A trifoliate species of Gardenia, about eight feet high, with flowers of the richest orange, produced wood resembling that of Box; the natives hung up branches of it as a charm against lightning. Two species of Mussenda: were shown, one of which (JZ. splen- dida, Welw.) was a climber, easy of propagation, and with red sepaline lobes. Lvstrostachys Welwitsch, Rchb. f., was a remarkable exception to its epiphytal allies in habit. © This grew upon the bare rock, spreading its branching roots upon the scanty soil. : Mr. Berkeley suggested that the peculiarities of the leaves of the Maranta were due to the convolute vernation. » EXTRACTS FROM PROCEEDINGS. Xlll Professor Thiselton Dyer stated that a very similar Phrynium, with weak, scrambling stems extending to twenty fect, is known from Upper Guinea. A note was read from Dr. Boswell-Syme, ‘‘ On the Fertilisation of Grasses” (Journ. N.S., iv., pp. 7-8). Mr. McLachlan stated that the flowers of Juncacee were visited by insects. A further note from Dr. Boswell-Syme stated that at Balmuto a Spanish Chestnut never fruits. The styles are apparently perfect, but the anthers are not developed from want of heat. At Culross, twenty miles to the west, by the Forth, which is much warmer, fruit is ripened in all but unfavourable years. Mr. Berkeley laid before the Committee specimens of Cinchona bark brought from the Nilghiris by Dr. Thomson, showing the rapid development of new bark in places from which the old bark had been previously stripped off, the exposed surface being protected from the action of the atmosphere by a covering of moss. Fifteen months is sufficient to reproduce bark fit for commercial purposes. GENERAL MEETING. ova J. Bareman, Esq., F.R.S., in the Chair. Mr. Berkeley remarked that the diseased Peach-trees, which have lately been brought several times under the notice of the Com- ’ mittee, had been affected partly by climatic conditions and partly by the bad state of their roots. The celebrated tree at Chatsworth, which had greatly declined, was effectually restored by supplying entirely new soil. As regarded some diseased shoots before the meeting, a specimen of the soil, consisting greatly of Beech-mast covered with fungous spawn, was a suflicient indication of the cause. It was, however, impossible always to assign the cause. Two seedling Figs raised by himself and Dr. Hogg were both affected by a similar canker. Specimens of Cinchona bark were sent by Dr. Thomsor fromthe Nilghiris, where the trees were allowed to grow three years before the bark was stripped off, a portion of the old bark being left, which caused the young bark to grow freely and well. Prof. Thiselton Dyer made some remarks on Dr. Welwitsch’s speci- XIV ROYAL HORTICULTURAL SOCIETY. mens laid before the Scientific Committee, showing the important. help which botanists could give by indicating plants fit for horti- culture. Ceylon, for example, contained a Gordonia quite un- known in Europe, except from dried specimens, which has flowers nearly four inches in diameter. May 1, 1872. FLORAL COMMITTEE. First-class Certificates were awarded to Mr. J. Linden for Odon- toglossum brevifolium ; to Messrs. Veitch for Pentstemon Menziesii, var. Robinsont ; to Messrs. Rollisson for Dracena lentiginosa ; to Mr. B. 8. Williams for Zamia cycadefolia ; to Mr. Croucher for Echinocactus Mirbelii ; to Messrs. Henderson for Bowvardia longifolia flammea ; to Messrs. Ivery for Azalea indica-Fanny Ivery ; to Mr. Turner for Alpine Auriculas, Mercury and Colonel Scott ; and to Mr. Hooper, Bath, for Pansies, Crimson Beauty, Mrs. Eyles, and Prince of Wales. A Cultural Commendation was awarded to Mr. Green for an interesting group of plants, amongst which were several species of Calochortus ; to Messrs. Veitch for varieties of Odontoglossum Alexandre; to J. Russell, Esq., for cut Orchids ; and to Mr. Baines for magnificent specimens of Sarracenias. Mr. Baines attri- buted the splendid state of the plants to their being kept only moderately moist to prevent rotting, while they require previously a constant supply of water during the period of growth, but not from a pan placed underthem. S. Drummondit alba must not be potted when the other forms are, in early spring, but in August, when all the old soil should be removed and replaced with the best fibrous peat, sphagnum, and sand. The Committee thought that they deserved a Silver Flora Medal. ROSE AND AZALEA SHOW. The Prizes in the Rose Classes were obtained as follows:—Mr. Turner and Messrs. Paul for nine; Messrs. Veitch for six. In the Amateur Class the best came from Mr. E. Ellis, gardener to J. Galsworthy, Esq.; Mr. Baxter, and Mr. J. James. In Azaleas a ie EXTRACTS FROM PROCEEDINGS. KV Messrs. Lane were first, Mr. F. Hill, gardener to H. Taylor, Esq., second, and Mr. Turner third. The First Prize for three, confined to Amateurs who had not previously taken the Society’s Prize for Azaleas, was gained by Mr. F. Hill; Mr. James was second, and Mr. J. Herrington third. For Auriculas Mr. Turner had the best twelve show varieties; the Rev. H. H. Dombrian the best six amongst Amateurs, and Mr. James was second, who also staged the best Calceolarias. Mr. Denning was first with Orchids, Mr. Bull second, and Mr. G. Wheeler third. Extra Prizes were awarded to Messrs. Veitch for Roses in pots, Japanese Maples, and Spireas; toe Mr. Noble for new varieties of Clematis, grouped with Spirea palmata ; to Mr. Turner for Roses; to Mr. B. 8. Williams for fine- foliaged and flowering plants; to Mr. Ware for hardy spring plants ; to Mr. W. Paul for Maréchal Niel and other cut Roses; to Mr. Denning for Orchids; and to Messrs. Standish for Hucharis amazonica. FRUIT COMMITTEE. A First-class Certificate was awarded to Mr. F. Dancer for Connover’s Colossal Asparagus, a very fine variety which is excellent when cooked. A Cultural Commendation was voted to Mr. Stevens, gardener to the Duke of Sutherland, for Black Circassian and Elton Cherries; to Mr. D. M‘Kellar, gardener to C. Magniac, Esq., for Marguerite Strawberries; to Mr. Hepper, gardener to E. D. Lee, Esq., for Dr. Hogg Strawberries; to Mr. J. Tegg, gardener to J. Walter, Esq., for Violette and Brown Turkey Figs and Grapes; and to Messrs. Wright for Black Hamburgh Grapes. SCIENTIFIC COMMITTEE. W. W. Savnpers, Esq., F.R.S., in the Chair. Mr. Berkeley reported, on the authority of Dr. Thwaites, that the Coffee Fungus in Ceylon was dying out. Mr. Berkeley also exhibited Peach-shoots ‘‘ gumming,”’ and re- peated his oft-expressed opinion, that the disease in question is due to alternations of temperature, and especially to the contact of cold water. ‘The circular holes in the leaves he attributed to drops XVI ROYAL HORTICULTURAL SOCIETY. of water, acting like burning lenses, or possibly by chilling the tissues. The Chairman expressed nis opinion that the holes in question were produced by insect-puncture (Thrips ?), and a consequent un- — equal contraction of the tissues of the leaf, ultimately resulting in the death of a circular portion of the leaf, and by its falling out leaving a hole as if punched out. The Chairman also showed a remarkable dwarf variety of Cupressus macrocarpa, about 4 inches high, and as many through. The plant, which was nine years old, had been obtained from seed by Messrs. Garraway, of Bristol. Some doubt was expressed as to its belonging to C. macrocarpa at all ; in any case it isa very remark- able plant, analogous in habit to the Clanbrasilian Fir. | The Chairman also exhibited bulbs of Amaryllis in a decayed state, and partially eaten by the larva of a Dipterous insect, Hristalis entricarius, which it is surmised might have been introduced with liquid manure. Mr. Miers exhibited specimens of a new and apparently valuable fibre, obtained from a Brazilian climbing plant with opposite leaves. The abr appeared so abundant and so good that further particulars were requested. Prof. Thiselton Dyer communicated an additional note with respect to Honey-Dew (Journ. N. S., vol. iv., pp. 6-7). GENERAL MEETING. James Bateman, Ksq., F.R.S., in the Chair. Mr. Marshall spoke very highly of Mr. Peacock’s collection of succulent plants as most worthy of inspection. In allusion to the poisoning of a clergyman in Norfolk by sus- picious Mushrooms, Mr. Berkeley advised amateurs to exercise very great caution before they ate doubtful kinds. Mr. Barvr’s splendid double Narcissi were obtained by Bee the planting of the bulbs till January. Prof. Thiselton Dyer called attention to the traces of inte con- colorous with those of the flowers in the foliage of Cinerarias. This was a matter of some theoretic interest, because it seemed to show that | the colours of flowers were produced by a process possibly of oxida- tion from elaborated matters, such as already existed in the foliage. It was known that, while deoxidation took place in the leaves, oxida- EXTRACTS FROM PROCEEDINGS. XVil tion was the rule in flowers ; perhaps it also took place in the hairs with which the under-surface of the Cineraria leaves were clothed, and in which the colour seemed to reside. A French chemist, Persoz, had grown plants of Impatiens in indigotic acid, and had found that the dye in-the leaves was deoxidised and bleached, whereas in the flowers the colour was restored. May 15, 1872. FLORAL COMMITTEE. First-class Certificates were given to Mr. Denning for an annamed species of Wasdevallia and Odontoglossum coronarium ; to M. Jean Verschaffelt for Agave robusta, A. Leopoldii, A. Killischir, and Buonapartea hystrix vera; to KE. Foster, Esq., for Show Pelar- goniums, Chancellor and Naomi; to Mr. D. 8. Thompson for Gloxinia, Cecilia; and to Mr. Turner for Carnations, Empress of Germany, Marchioness of Westminster, and Princess Christian, and for Azalea grandis, the best salmon-red yet seen. Cultural Com- mendations were awarded to Mr. Chambers, gardener to J. Lau- rence, Esq., for cut blooms of Rhododendron Dalhousianum ; to Mr. Green for Bromeliads; and to Mr. R. Dean for a new Wallflower- leaved pyramidal Stock. SECOND MAY SHOW. Mr. Turner and Messrs. Paul had a hard contest for the principal Rose Class, as also for twelve specimen plants of Roses. The Prizes given by Mr. Peacock for twenty-four distinct species of Agave were gained by W. B. Kellock, Esq., and M. Verschaffelt, to whom several First-class Certificates were awarded. The best ‘twelve hardy perennials came from Mr. R. Parker and Mr. Ware. _ Mr. Turner took the Prize for Carnations, given by G. R. G. Ricketts, Esq. Extra Prizes were awarded to Mr. B. S. Williams for a large group of flowering plants, including many novelties ; to Messrs.

Dobson for herbaceous Calceolarias; to Mr. W. Davis for Show Pelargoniums, excellent market varieties; to Mr. W. Paul for cut Roses; to Messrs. Standish for Hucharis amazonica; and to M. Verschaffelt for a very handsome pair of Bay Trees. FRUIT COMMITTEE. A First-class Certificate was given to Mr. J. Munro for his seedling Melon, ‘‘ Little Heath,” a scarlet-fleshed acquisition for early work, and which is very prolific. A Cultural Commendation was given to Mr. J. Tegg, gardener to J. Walter, Esq., for Black Hamburgh and Buckland Sweet Water Grapes, and nicely-coloured fruit of Grosse Mignonne Peach. Mr. Gardiner sent Apricots and Pear shoots, to illustrate the beneficial effects of protecting the trees when in bloom with (Frigi Domo) canvas. Henry Webb, Esq., sent Pears attacked by a small fly, and offered a Prize of £5 to anyone who will point out how the evil effects of the insect can be prevented. Messrs. Carter’s Prizes for First Crop Pea were taken by Mr. J. W. Chard, Mr. G. Brown being second, who was first in the other Class with Little Gem. SCIENTIFIC COMMITTEE. W. W. Saunpers, Esq., F.R.S., in the Chair. Mr. Berkeley made some remarks with respect to the Austra- lian Vine Disease, described in the ‘‘ Gardeners’ Chronicle,” May 4, 1872 (pp. 607-8), by Mr. McArthur. The spots on the berries were not the same as those on the stems; they were uncon- nected with any fungoid growth, but the former were perhaps due to a Glaosporium or Phoma. He understood that in the year when the disease had been at its worst, there had been a rainfall of sixty inches; he concluded that this had something to do with the matter, though the disease appeared to have existed in Australia from the earliest period of Vine cultivation. 7 Mr. Berkeley also exhibited a Vine shoot from his own vinery, which had rotted at the nodes in a quite unaccountable way. He could not help thinking that this had something in common with the disease which proved so fatal to Phalenopsis. Too much moisture at the roots, arising from the superabundant rainfall, was suggested as the cause of the malady in Mr. Berkeley’s case. Leaves of an Apricot were shown, which appeared to have a - > ~F Se FOR OL age - ges EXTRACTS FROM PROCEEDINGS. xix been attacked by some small Lepidopterous larva, probably belong- ing to the family of the Zortricide. A communication was read from Mr. Anderson-Henry ‘On Hybrids of Arabis,” published in the ‘‘ Gardeners’ Chronicle,”’ May 18, 1872 (pp. 671—2). [From notes by Prof. Thiselton Dyer and Mr. Anderson-Henry, published in the ‘‘ Gardeners’ Chronicle ” for July 27 and August 3, 1872 (pp. 1007 and 1040), some acci- dental error would appear to have vitiated the experiments. | Mr. W. W. Saunders exhibited a stem of sprouting Broccoli, which having been cut too low down, had thrown out numerous adventitious buds below ground from its roots. (See accompanying woodcuts. ) xX ROYAL HORTICULTURAL SOCIETY. | ! Mr. Andrew Murray showed specimens to prove that Dr. Roberts’s method of treating trees affected with Scolytus could do little to repair their already diseased condition. Courval’s plan of dressing the trees after pruning equally failed to produce any true union between the old wood and the new. Mr. McLachlan said that it was only trees which were already diseased which were attacked by the Scolytus; the insect, in fact, had no chance except in a feeble tree. Mr. Wallace and Mr. Bates equally failed to find wood-eating beetles in the native forests ; they were only met with where clearings were being made. GENERAL MEETING. W. W. Savunpers, Esq., F.R.S., in the Chair. Mr. Berkeley brought a flowering plant of Lupinus rivularis, raised from seeds gathered on the banks of the Dee below Ballater, where it is perfectly naturalised. He then alluded to a case of disease in the Vine, which attacked the nodes, causing them to break off, and which he thought was due to excessively wet weather, in which he was confirmed by Mr. Barron. EXTRACTS FROM PROCEEDINGS. XxXl Mr. Bateman remarked that dried specimens of Odontoglossum coronarvum had been received with seventy flowers on a spike. Professor Thiselton Dyer made some remarks on the varieties of Kale cultivated at Chiswick, an account of which has been given in the Journal, N.S., vol. ii., p. 171, by Dr. Hogg. He stated that many of the Plum blossoms in the Orchard House at Chiswick had two carpels, the groove being ventral; and Mr. Berkeley had in- formed him that in late-developed flowers he had seen the complete number of five carpels. FLORAL COMMITTER. First-class Certificates were awarded to Mr. Denning for Utricu- larva montana and the extraordinary Orchid Wanodes Meduse ; to Messrs.

Aralia Veitchii obtained a Gold Medal as the best new Plant not in flower and not in commerce; Mr. Bull being second with Croton maesticum. Messrs. Veitch were first for twelve new plants in or out of flower, Mr. Bull second; and the position was the same for six. Mr. Ward was first for nine and six Heaths, Mr. J. Wheeler and Messrs. Jackson being second. In Orchids Mr. B. 8. Williams was first, Mr. Bull second, while Mr. Ward had the best twelve in the Open Class. Mr. G. Wheeler was the only exhibitor in the Class for Amateurs who had not pre- — viously taken the Society’s Prize for Orchids. In Ferns the best stove and greenhouse species were staged by Mr. Baines and Mr. B. 8. Williams. Show Pelargoniums were a striking feature of the Show, Mr. Ward being first, Mr. James Weir second, and Mr. James third. Mr. D. Donald had the best Fancies, Mr. Bone being second. Messrs. Paul were first for cut Roses, and Messrs. Kelway second. M. Pfersdoff staged a fine collection of Cacti which obtained the Prize offered by Mr. Peacock, who is now possessor of the plants. FRUIT COMMITTEE. Cultural Commendations were awarded to A. Smee, Esq., for White Juneating Apples grown in an orchard-house ; and to Mr. Colbourne, gardener to J. Blyth, Esq., for a dish of Loquat of first- rate flavour. A new white silver Tripoli Onion called Marzagola was sent by Mr. Piccirillo, and Messrs. Criscuolo the true White Nocera from Naples. The collection of fruit at the Summer Sion was large; Mr. Lynn, gardener to Lord Boston, was first for eight distinct dishes of fruit, Mr. Bannerman being almost equal. Mr. D. Wilson was first for Queen Pine, Messrs. Yates second, and Mr. J. Hepper third. Mr. Wilson was first with a handsome smooth Cayenne, followed by Mr. Bland and Mr. Douglas. Mr. Sage was first for Grapes, Mr. Henderson second, Mr. Craven third, and Mr. Banner- man fourth. For a single dish of Hamburgh or Frankenthal, Mr. Douglas first, Messrs.

For a single dish of Muscat, Mr: G. Osborn was first, Mr. D. Pizzey second, and Mr. Kemp third. Mr. Douglas was also first for any other dish of White Grape, with splendid examples of Buckland Sweetwater ; Mr. Craven second and Mr. Roe third with Golden Hamburgh. Mr. Kemp and Mr. Pizzey were first and second for White Fron- tignan, Mr. Bannerman third with Grizzly Frontignan. Mr. Brown, gardener to Earl Howe, Mr. Gardiner, and Mr. G. T. Miles, gardener to Lord Carrington, were the successful exhibitors of Peaches, Mr. Miles being first, Mr. Gardiner second with Elruge Nectarines. Brown Turkey Figs came from Mr. Miles, Mr. Sage, and Mr. C. Ross. Mr. Miles also had two First Prizes for Black Cir- eassian and Elton Cherries. Mr. Douglas was first for Strawberries, Mr. Lynn second. The Melons were inferior in flavour, the Prizes being awarded to Mr. Lamb, gardener to G. T. Davie, Esq., for Colston Basset Seedling; Mr. Bannerman and Mr. Lynn succeeding with Victory of Bath. In the scarlet-fleshed series Mr. Douglas had Scarlet Gem, Mr. Munro second with Little Heath, Mr. Lynn third. SCIENTIFIC COMMITTEE. W. W. Savnpers, Esq., F.R.S., in the Chair. The Belgian Delegates, MM. de Cannaert d’Hamale, Kegeljan, and Morren, and Mr. Haliburton, from Nova Scotia, attended the meeting. Mr. Berkeley brought a specimen of Pear blossom with a second ~ generation of buds arising from the pedicels. He also showed branches of a Pine the tips of which were dis- torted by a minute Coccus. Mr. Smee brought specimens of Almond and Peach leaves blistered, as Mr. Berkeley supposed, by a minute Fungus. Mr. Smee was disposed to attribute it, however, to the action of an Aphis. He brought in illustration Currant leaves clearly blistered by the Aphis which was so destructive last year. Some trees were quite killed by it, but others sprouted freely, and he had observed that the new shoots were attacked by an Aphis of quite a different kind. Branches of Juniper were shown by Dr. Masters swollen by a species of Podisoma which, like Cyttarza and Apodanthes, produces a new crop year after year. XXLV ROYAL HORTICULTURAL SOCIETY. Also some cuttings of Hydrangea, which were rotten and° mouldy at the base, apparently from over-watering. Professor Morren stated that Lychnis F'los-cuculi sometimes pro- duces apetalous flowers, in which the stamens are replaced by carpels, as in the common Wallflower. Mr. Berkeley stated that he had again examined the specimens of Black Spot from Australia, and found that there was clearly a species of Glaosporium in the spots on the fruit, but he was not at present prepared to say as muck as to those on the stem, GENERAL MEETING. W. W. Sacnvers, Esq., F.R.S., in the Chair. he Mr. Marshall stated that last winter Dr. Denny had told him that amongst Zonal Pelargoniums there appeared to be two strains, one of which would not submit to forcing operations. Mr. Berkeley stated that Utricularia montana was U. alpina, Linn. He again referred the blister in Peach and Almond leaves to a parasitic Fungus, belonging to the genus Ascomyces. With reference to Bornet’s paper on the nature of the gonidia of Lichens, read before the Academy of Sciences in Paris, he stated that Dr. Thwaites had long since shown that certain supposed Alge were mere states of Lichens, a different type prevailing in different genera. Mr. Berkeley by no means agreed with the notion that Lichens are Fungi parasitic on Alge. ee JUNE 19, 1872. FLORAL COMMITTEE. First-class Certificates were given to W.

In the Amateurs’ Class for six Zonal Pelargoniums Mr. Weston, gardener to D. Martineau, Esq., obtained a Second Prize. An Extra Prize was voted to Mr. Catlin for six which did not arrive in time to compete. Messrs. Wright took a Second Prize in the Nurseryman’s Class, and the same for six double Pelargoniums. Mr. Watson was first for variegated Zonals; Mr. Welch second. In the Nurseryman’s Class Mr. Pestiidge was first, Mr. Stevens second, and Mr. Turner third. The Fuchsias were scarcely of average merit. In Palms Mr. Williams was first with a splendid group, Mr. Bull second, Messrs. Rollisson third. In the Amateurs’ Class the principal exhibitors were Mr. J. Hill, Mr. Cole, and Mr. G. Wheeler. Mr. Dombrain was first for twelve Ranunculi, Mr. Hooper second. The Metropolitan Floral Society offered Prizes for twenty four, and they were won by the same exhibitors, Mr. Hooper having the best. Prizes were also offered for stands of twenty-four Pinks, for which Mr. Turvey, Mr. Pizzey, and Mr. _ Hooper were successful. SCIENTIFIC COMMITTEE. Anprew Murray, F.I.S., in the Chair. The Chairman laid before the Committee leaves of Hedera Regneriana in a diseased condition, sent by the editor of the ‘‘Gar- den.”” Mr. Berkeley subsequently reported this to be due toa species of Thrips; there was also a Coccus, but only one indi- vidual was found. Mr. Worthington Smith sent a woody excrescence from the stem of a Cupressus. It was cushion-shaped, comparatively soft in texture, and attached to a very short pedicel. Its analogy was suggested to the excrescences on Camellia, described and figured in the Gard. Chron., 1870, p. 1116. Dr. Masters read a note upon some roots which had obstructed _four-inch pipe-drains sunk to a depth of four feet in some old per- manent pasture, and which had been sent to him by Mr. Grantham. Dr. Masters having found in them bright yellow sinuous latici- ferous vessels, concluded that they were the roots of some Thistle. Prof. Voelcker had seen the roots of Marigolds in drains three VOL.

Mr. McLachlan mentioned that Phyllotreta obscurella, a species of Halticide, very common on edible cruciferous plants, had been found in multitudes destroying the petals of Limnanthes Douglasi, but leaving untouched neighbouring plants of other natural orders. Reference being made, at the suggestion of Dr. Masters, to a paper by Chatin (Ann. d. Sc. Nat, 1856, vi. 256), it was ascertained that Limnanthes, like Trope@olum, appeared to contain allyl sulpho- CsH; CN Mr. Marshall sent flowers of two varieties of Gloxinia, G.

He also sent a monstrous flower of an Odontoglossum, which was referred to Dr. Masters for a report. cyanide, S, which was also present in Crucifers. GENERAL MEETING. | James Bateman, Esq., F.R.S., in the Chair. Professor Thiselton Dyer called attention to a pot of Gym- nadenia Conopsea, showing that our native Orchids are capable of becoming striking plants in cultivation. Ophrys apifera, var. Trollii, also from the Chairman, was new to this country. The plants were obtained in the neighbourhood of teigate. Hpidendrum nemorale, Lindl., was figured in Bot. Mag. under the name of £. verrucosum. It succeeds best under a cool - treatment. Botryodendron magnificum is no doubt the same as Meryta latifolia, Bot. Mag., t. 5932. The specimens from Strath- fieldsaye, supposed to be Derospyros lucida, were probably Nyssa multiflora. The bright crimson tint of the leaves in autumn is characteristic in North America, where it is known under the name of Tupelo or Pepperidge. A plant of TZozxicophlea, from the smaller limb of the corolla, was probably 7. Thunbergii rather than T. spectabilis. An almost unknown Lily, which Mr. Wilson had shown in flower, Z. californicum, hitherto not seen by Baker and Duchartre, was clearly an ally of ZL. superbum. a a ee $ ¥ EXTRACTS FROM PROCEEDINGS.

Cultural Commendations were awarded to Mr. T. Burnett, gardener to W. Terry, Esq., for Anectochilus Lowi; and to Mr. J. Lawrence for Mazxillaria venusta. Mr. Wilson brought flowering plants of a Lily found by Mr. Robinson on the Rocky Mountains, with flowers nearly resembling those of Z. puberulum, but quite distinct in the foliage, the beautiful Z. canadense flavum, and a fine variety of ZL. longiflorum. FRUIT COMMITTEE. A First-class Certificate was given to Mr. Laxton for a seedling _ Strawberry named Traveller, a cross between Sir C. Napier and La Constante.

The substance in question consists almost entirely of carbonate of lime, and was stated to be the core of a species of Sea Pen ( Osteocella septentrionalis). A question then arose as to whether pollen-eating beetles were serviceable to flowers or not; the general impression was that the beetles in question did as much good as harm. Professor Thiselton Dyer exhibited specimens of the ash and scoriz from the recent eruption of Vesuvius. The ash is known to have powerful fertilising properties, owing to its being rich in alkalies and containing phosphates. The fertility of the soil so induced affords one reason for the return of the population to such dangerous localities after an eruption. Mr. A. W. Bennett alluded to a paper of Professor Pasqaiat 8, in which the injury to vegetation after the eruption of a volcano was stated to be the result of the chloride of sodium deposited on the leaves. Professor Thiselton Dyer showed Rhubarb leaves from Mr. Schofield’s garden at Mosely, near Birmingham, riddled with large holes made by hailstones in the recent storm. Mr. G. F. Wilson showed a box useful whilst on a journey for collecting living plants, and further alluded to at the General Meeting. GENERAL MEETING. James Bateman, Esq., F.R.S., in the Chair. Mr. Berkeley alluded to a new but very simple form of collecting- box, designed by Mr. James Atkins, of Painswick, for collecting plants in Switzerland, and exhibited by Mr. Wilson. The box before the meeting contained roots of several different plants, including the Holly Fern, collected on a high hill in Perthshire, June 14, and which were now in excellent condition. The storm at Birmingham of Tuesday, June 18, continued for four hours, during which the rainfall was 2°5 inches, two inches at least coming down in forty-five minutes.

Bryant, for Carnation, Superb, and for Zonal Pelargonium, Mr. Quilter; to Mr. J. King, gardener to the Rev. J. S. Wiggett, for Zonal Pelargonium, Pink Pearl. Mr. Wilson also sent Lilium tigrinum erectum, and a dwarf deep-red form, which was named JZ. concolor sinicum. Messrs. Jackman received the First Prize for Clematis; and the same was awarded to Mr. Wilson for Lilies, which, however, as a Member of the Couneil, he could not take. First-class Certificates were given for LZ. tagrinum splendens and L. japonicum Takesima. Mr. Bull received the First Prize for six Lilies in the Nursery- man’s Class, and for .six Gesneriacee. Mr. Parker was first for hardy perennials. An Extra Prize was awarded to Mr. Turner for eighteen boxes of cut Roses in splendid condition; he was also first for Carnations, and also for Picotees not yet in commerce, followed by Mr. N. Norman. The Metropolitan Floral Society gave Prizes for Carnations and Picotees, which were taken in both classes by Mr. Pizzey and Mr. Norman. Amongst Mr. Turner’s - Picotees and Carnations, First-class Certificates were given to Picotees Mrs. Fordham, Edith Dombrain, Mrs. Hornby, Juliana, Norfolk Beauty, and Ethel ; Carnations, Mrs. rid Burnaby, Isaac Wilkinson, and Campanini.

A copy of a communication to the Foreign Office from H.M.’s — Minister at Lisbon, alluding to the new Vine Disease in Portugal, was brought before the Committee. Dr. Masters made a statement with respect to the management of the Royal Gardens at Kew; and the following resolution was proposed by Mr. Grote, seconded by Dr. Gilbert, and carried unanimously :— “That the members of the Scientific Committee of the Royal Horticul- tural Society, having regard to the present question between Dr. Hooker and Mr. Ayrton, desire to express their sense of the importance of Dr. Hooker’s efforts to maintain unimpaired the scientific character of Kew, asan establishment indispensable to Horticultural and Botanical Science ; and are further unanimous in giving their support to the memorial which has already been forwarded to Mr. Gladstone.” Prof. Thiselton Dyer said, with reference to the hybrid seedlings which had been communicated by Mr. Anderson-Henry on May 15 (see p. xix.), and in which the second generation exhibited extreme divergence both from their hybrid parent and the original species of which it was a cross, he could not refrain from suspecting some error. Every botanist who had examined the plants of the second generation had pronounced them without doubt to be ordinary Arabis hirsuta. (Mr. Anderson-Henry acquiesced in this opinion— Gard. Chron., 1872, p. 1040—and allowed that some error must have been made.) GENERAL MEETING. J. Bateman, Esq., F.R.S., in the Chair.

Standish sent a collection of cut spikes of Gladiolus, most of which were raised from a cross between G. cruentus and the best French varieties, by which it is hoped that the constitution will be improved. For these an Extra Prize was awarded. Mr. Bull’s collection of Arads, including a magnificent specimen of Godwinia gigas, excited much interest. A Cultural Commendation ‘was given to Messrs.

Two bunches of the new white Grape, Duke of Buccleuch, were exhibited, and Mr. Barron was deputed by the meeting to go to the Vineries at Tweedside to report on it im situ. A Cultural Commendation was given to Messrs. Lane for a collection of Grapes. A First-class Certificate was given to Mr. J. Henson, Newark, near Peterborough, for a large round dark-red Gooseberry, named Henson’s Seedling. Fine clusters of the fruit of Habrothamnus elegans came from the Marquis of Salisbury. Mr. Clark, gardener to Major-General Claremont, took the Prize for Plums; Mr. Beach was first, and Mr. Earley second, for Gooseberries. The six heaviest Gooseberries came from Mr. Kirtland. XXX1i ROYAL HORTICULTURAL SOCIETY. GENERAL MEETING. W. W. Saunners, Esq., F.R.S., in the Chair. Mr. Berkeley read a letter from Mr. Smee relative to a Fungus which was destroying Willows in his garden, specimens of which were produced ; but asit was only in the mycelioid state of growth, it was impossible to say precisely what the perfect plant would prove. It might possibly be Zrametes suaveolens. Professor Thiselton Dyer called the attention of the meeting to a drawing of a tropical fruit from Dr. Moore. It appeared to be that of Lucuma obovata, a native of Temperate Peru, and cultivated in Chili. It had fruited this year, probably for the first time in this country. According to Professor Pasquale, the volcanic ashes brought at the last meeting, from containing sodium chloride, were injurious to the foliage of plants at the time of the eruption. Dr. Flight had been so kind as to examine a portion. A considerable portion was soluble in water, and the two chief salts were sodium chloride and calcium sulphate (common salt and gypsum). ‘‘ There is a little soluble silicate also. There is certainly ammonia (not much), I suppose in the state of chloride. Of phosphoric acid the merest trace, still a trace. Of potash, which I looked for sharply, there is none. Of course I have only examined the watery extract.” This threw some light upon the usefulness of the ash as manure. Onions contain allyl sulphide; their tissue also contain abundance of minute crystals of calcium oxalate. The calcium sulphate would supply both the sulphur and the calcium, which the Onion invariably contains. It would conduce, therefore, to its vigorous development. Mr. F. Antoine had sent for the Lindley Library a beautiful and interesting work, illustrative of the Winter Garden at Vienna. Avueust 21, 1872. FLORAL COMMITTEE.

Kelway obtained a First Class for Gladiolus Orcus, Lycoris, Lamirus, Osci, and Heloris; and Mr. Douglas for Rosy Morn, Gwendoline, Morgan, and Day Dream. A Cultural Commendation was given to Mr. Baines for a wonderful specimen of Mepenthes Rafflesiana, with fifty pitchers. It was also recommended that it should have a Lindley Medal. (See woodcut on following page.) A First-class Certificate was given to Phlox Heynholdw cardinalis, pale brick-red with crimson eye, from the Society's Garden at Chiswick ; and to Mr. G. Smith for Fuchsia, Delight, with a large white corolla. Messrs. Kelway were first for twenty-four distinct Gladioli, Mr. Douglas second, Messrs. Standish third, and Mr. Welch fourth. Lord Hawke was the winner in the Amateur Class for twelve Mr. J. Douglas second, the Rev. H. H. Dombrain third. Mr. Dombrain was first for six, Rev. Lord Hawke second, the Rev. J. 8. Hodgson third, Mr. Douglas fourth. Mr. Parker and Messrs. Downie Laird and Laing competed for twelve cut Phloxes, the latter being first for twelve hardy perennials. FRUIT COMMITTEE. Mr. Barron reported on the Duke of Buccleuch Grape as a very valuable summer Grape, but which would not keep long after being ripe, as it is thin-skinned. It is extremely pleasant to eat, the flesh tender and juicy, with a rich sparkling acidity somewhat of the Hamburgh character. A First-class Certificate was accord- ingly awarded. Messrs. Carter offered Prizes for Runners and French Beans, including Carter’s Champion. Mr. Ross was first, Mr. Frisby second. Mr. J. Smith, gardener to the Earl of Gains- borough, made a communication as to the effect of lifting and renewing the soil in preventing shanking in Grapes, a circumstance which cannot be too carefully kept in mind in many other cases of disease. GENERAL MEETING. W. Marsaatt, Esq., in the Chair. The Sooly Qua Cucumber, which is clearly Luffa egyptiaca, is much valued by the Chinese in California. Mr. Baines has ROYAL TWORTICULTURKAL SOCIETY. XXX1V EXTRACTS FROM PROCEEDINGS. XXXV stated that such fine pitchers as those which appeared at the last meeting in Nepenthes could only be obtained on young plants. He grows the plant in sifted fibrous peat, giving plenty of water and air. It must be kept as near to the glass as possible, and as regards temperature those who had a house in which Cucumbers were grown all the year round could grow the Pitcher plant in perfection. es SEPTEMBER 4, 1872. oe FLORAL COMMITTEE. A First-class Certificate was given to Messrs. Veitch for Dzp- ladenia insignis; to Messrs. Henderson for Ceanothus, Gloire de Versailles, and Cineraria ceratophylla ; to Mr. Chambers, gardener .o J. Lawrence, Esq., for Pteris serrulata fimbriata and Pteris serrulata cristata superba, a compact and neat-growing form of such excellence that every gardener would find it useful ; to Mr. Parsons, gardener to W. J. Blake, Esq., for a new Achimenes, Firefly; to Mr. C. J. Perry for Verbena, Reynolds Hole; and to Mr. Eckford, gardener to the Farl of Radnor, for Verbena, Fanny Purchase, _ Verbena Star, and Dahlia, Crown Prince; to Mr. Keynes for Dahlia, Ada Tiffin, Egyptian Prince, Matilda Mary Purchase, and Mr. Sinclair ; to Mr. Turner for Florence Pontin and Lord Hawke ; and to Mr. Dean for Zagetes aurea floribunda. Mr. Keynes, Mr. Turner, and Mr. Scale obtained the Prizes for twenty-four cut blooms of Aster. In the Amateurs’ Class for twelve Mr. C. J. Perry was first, Mr. Beach second, and Mr. Burfitt, gardener to C. Lambert, Esq., third. Mr. Rowe and Mr. S. Wheeler obtained other Prizes in the different classes. Mr. Perry was first for Verbenas. Mr. Paul took the Prize for Lilium speciosum, and an extra Prize for seedlings grown in Holland. Messrs. Standish had a First-class Certificate for Juniperus japonica aurea. FRUIT COMMITTEE. . Lady Charles Wellesley sent a fine cone of Araucaria imbricata from whose seeds young plants have been raised. Mr. Pearson XXXV1 ROYAL HORTICULTURAL SOCIETY. sent, amongst other seedling Grapes, one remarkable for its strong barley-sugar flavour. Mr. G. F. Wilson brought examples of the Melon Apple, which ought to be in every orchard-house for its beauty and fine flavour. Mr. Dean brought jelly of Berberis Aqui- folium, and Blackberry jam flavoured with the fruit of the Berberis. GENERAL MEETING. G. F. Witson, F.R.S., in the Chair. The Dipladenia insignis was stated to be a great advance from a horticultural point of view; but compared with coloured illustra- tions of D. crassinoda (properly Martiana), it could only be re- garded botanically as a variety of that species. SEPTEMBER 18, 1872. FLORAL COMMITTEE. First-class Certificates were given to Mr. Croucher for Agave Guilbeyt and A. striata Richardsu ; to Messrs. Lee for Cornus mascula aurea elegantissima ; to Mr. Turner for Dahlia, Laura Haslam, Prince . Arthur, Nelly, and Arbitrator ; to Messrs. Henderson for anew As- plenium, near to A. bulbiferum, var. incisum; to Mr. Stevens for Ver- bena, Prince of Wales; and to Mr. Eckford for Verbena, Mrs. Lew- ington, Star, and Dahlia, Walter Reid, Queen’s Messenger, and Cre- — morne. Messrs. Standish exhibited a series of seedling Rhododendrons showing the effect of the pollen-parent in hybridising. The speci- mens supported Dr. Denny’s view that, ceteris paribus, the influence of the pollen-parent is predominant in the offspring. Mr. M. Walker, gardener to H. J. Atkinson, Esq., and Mr. Farrow were first and second for fine-foliaged Begonias. A Cultural Commen- dation was awarded to Mr. Wilson, gardener to W. Marshall, Esq., for Platycerium grande and P. Stemmaria, with seedlings of both; and to Mr. M. Walker for a good specimen of Hucharis amazonica. EXTRACTS FROM PROCEEDINGS. XXXVI11 FRUIT COMMITTEE. Messrs. Carter offered a prize for Beet, including their Perfec- tion, which was taken by Mr. W. G. Pragnell, who also won their First Prize for Onions, the second being given to Mr. Cross, gardener to J. D, Lousada, Esq. A First-class Certificate was awarded to Mr. Peasgood, Stamford, for a seedling Apple, named Peasgood’s Nonsuch, of the Blenheim Orange type. A Cultural Commendation was awarded to Mr. King, gardener to J. Baum, Esq., for Pot Vines. Prizes for Tomatoes were taken by Mr. Pragnell, Mr. George, Mr. Earley, and Mr. Roberts. Hathaway’s Excelsior, an introduction from America, came from Chiswick, certainly the finest type yet seen. Prizes for Dessert Apples were taken by Mr. E. Clarke and Mr. Earley, Mr. Donaldson taking the first in Pears. GENERAL MEETING. W. W. Saunpers, Esq., F.R.S., in the Chair. Professor Dyer stated that Amorphophallus campanulatus is culti- vated in India, as in Coromandel, for the starch in its curious root-stock. The so-called Asmah Vegetable Marrows were Lage- naria vulgaris, which Mr. Berkeley had more than once pointed out as suspicious and sometimes poisonous. He then made some remarks on the Potato disease, calling attention to the present state of our knowledge on the Ses as also to what is known about the Phylloxera. The Chairman stated that: as soon as the flowers of Amorphophallus have thrown out their objectionable odour, the temperature of the spathe rises some 4° or 5°. OcroBER 2, 1872. FLORAL COMMITTEE. Mr. Bull obtained a First-class Certificate for Dracena gloriosa, for Macrozamia pulchra, for Helminthostachys verticillata an ally of Ophioglossum, and for Cinocarpus dealbatus, a glaucous-leaved XXXVill ROYAL HORTICULTURAL SOCTETY. ‘Palm from Brazil. First-class Certificates were also awarded to Mr. Wilson, gardener to W. Marshall, Esq., for Zhamnopteris Nidus ramosa; to Anchusa capensis from Chiswick; and to Messrs. Hen- derson for Colchicum autumnale album plenum ; to Mr. Parsons for Asplenium Adiantum nigrum Serpentini; and to Mr. Dean fora dwarf French Marigold, with yellow- crimson flowers, and his new variety named aurea floribunda. Mr. Ingram sent from Belvoir a hybrid between Pachyphytum bracteatum and Echeveria secunda glauca, a promising plant for bedding out. FRUIT COMMITTEE. Cultural Commendations were awarded to Messrs. Veitch for an excellent collection of Endive; to Mr. Jones for smooth-leaved Cayenne Pines; to Mr. Wells for Black Hamburgh Grapes; to Black Hamburgh and Madresfield Court, grown at Chiswick with- out artificial heat; and to Mr. Fenn for a collection of Potatos. Messrs. Carter’s Prize for Potatos, including Carter’s Ashtop Fluke, were taken by Mr. Fenn; Mr. Miller, gardener to F. T. Friend, Esq., being second. Messrs. Lane were first for collections of black and white Grapes; they were again first for a single bunch of Muscat of Alexandria, Mr. Cole being second. Mr. Jones sent specimens of Golden Queen Pear, raised at Frogmore. Mr. Dean sent specimens of Californian Mammoth White Radish, a variety similar to which is cultivated in Hungary. Mr. Fenn brought samples of wine from English-grown Grapes, which were thought very satisfactory: the best was made from Esperione in 1870, and the next a mixture of Royal Muscadine and Esperione, a good dry wine. FUNGUS SHOW. Many novelties were produced, besides the more ordinary forms of edible and doubtful Fungi, which it is the great object of the Society to make familiar with its members. Amongst the rarer kinds were magnificent specimens of Lactarius controversus from Dr. Bull. Mr. English sent a Hydnum from Epping (where Mr. W. G. Smith found Radulum fagineum), which is certainly new to great Britain, and which was believed to be H. cirrhatum. There were also fine specimens of Thelephora multizonata and T. Sowerber, the former from Epping, EXTRACTS FROM PROCEEDINGS. EER ( the latter from Hereford. Mr. Austin had Hygrophorus obrusseus and Cortinarius armillatus. Three fine specimens of Sparassis crispa were sent from Gordon Castle, and Clavaria formosa came from Mr. Broome. The Prizes were awarded to Mr. J. English, and to Messrs. Austin and Hoyle. For the collection of edible Fungi the latter gentlemen were first and Mr. English second. An Extra Prize was awarded to Mr. W. G. Smith. GENERAL MEETING. W. W. Saunovers, Esq., F.R.S., in the Chair. Mr. Berkeley, alluding to Mr. Henderson’s double white Colchicum, stated that Mr. Barr had several double varieties which had not yet been exhibited. They are most easy of cultivation, and make a great show in autumn when planted in tolerably- sized patches. Attention was called to the Chairman’s plant of Tupistra nutans, a very singular production, now referred to Liliaceze. Some of the varieties of the Bottle Gourd are very bitter and poisonous, and as none are really good they should be altogether avoided as esculents. Captain E. G. Berkeley had lately seen the original tree of Amherstia nobilis, which is flourishing; the stem is now twelve feet in circumference. He found two Fungi for sale in the Bazaar at Amherst, one a Bovista. Mr. Berkeley directed attention to the further study of the Peronos- pora to which the Potato disease is due, with a view to the dis- covery of its resting spores, a NovEMBER 6, 1872. FLORAL COMMITTEE, A First-class Certificate was awarded to Mr. Croucher for the Mexican Yucca Fylesii, which has a woody stem eight feet high, swollen at the base, and straight glaucous tapering leaves ; also for Mammillaria Peacockii, Pilocereus Peacockii, P. Hoppenstedtii, and * Gasteria Peacockii. The Gasteria is said to be a hybrid raised by xl ROYAL HORTICULTURAL SOCIETY. M Pfersdorff. Agave Palmerii in the same collection was con- sidered to be young A. Verschaffeltti. The same award was made to Mr. Kowe, gardener to Mrs. Lewis, for Japanese Chrysanthemum, Elaine; to Messrs. Veitch for Dracena imperialis and Maranta olivaris Makoyana, also Malortiea simplex, Calamus ovoideus, and C. Roxburgh. Messrs Dixon had the best large-flowered Chrysan- themums, and Mr. Rowe the finest Pompons. FRUIT COMMITTEE. A First-class Certificate was awarded to Mr. Ross, gardener to C. Eyre, Esq., for an Apple allied to the Blenheim Orange, of a’ beautiful colour and excellent flavour. Cultural Commendations were given to a large gourd-like fruit, called Toong Qua /Benincasa certfera), from Mr. Temple, gardener to Lord Aylesford; to Mr. D. Cunningham, gardener to Lord Ebury, and Mr. Davidson, for large specimens of the fruit of Passeflora macrocarpa. The Prizes for Pears were taken by Mr. Fowle, Mr. P. F. Le Sueur, and Mr. G. T. Miles; for Potatos, by M. J. Betteridge, Mr. R. Dean, and Mr. P. McKinlay. Messrs. Carter staged seventy- two varieties of Potatos, with Nazeby Mammoth Onion. Messrs. Lee also sent a good collection. INTERNATIONAL FRUIT SHOW. The Gold Medal for the most complete collection of Grapes was gained by Messrs. Lane, who staged seventeen varieties; the Silver-gilt Medal by Mr. Donaldson, gardener to Lord Chesham. For the best basket of not less than twelve pounds the First Prize was given to Messrs. Lane; the second to Mr. Ward, gardener to T. N. Miller, Esq.; the third to Mr. Cole. Messrs. Lane were also first for a single dish of Muscat of Alexandria; Mr. Cole second; and Mr. Deuxberry, gardener to Earl Darnley, third. For Black Hamburgh or Frankenthal, Mr. P. F. Le Sueur was first ; Mr. Davis, gardener to E Rosher, Esq., second. Fora single dish of any other Black Grape, Mr. Toomer, gardener to W. Knowles, Esq., was first; Mr. Silcouk second. There was a good competition. Mr. Silcock was first with Trebbiano for a white variety other than sorts specially named. Fa tis a SM RN £OVe : z TABLE OF CONTENTS.

Passiflora tomentosa, var. 8. mollissima, Triana and Planchon, in Ann. Sc. Nat., Ser. 5 (1873), xvii., 181. New Granada. Messrs. Triana and Planchon state that they find no difference between the Peruvian Zucsonia tomentosa and the New Granadan 7. mollissima, except that the flower-tube is slightly pubescent in 7. tomentosa, while it is quite glabrous in J. mollissima In this opinion I cannot concur. The leaf-lobes of Z. mollissima, as I understand it, are ovate- lanceolate or lanceolate, instead of broadly ovate; they are downy on both surfaces, instead of being nearly glabrous above, as in 7 tomentosa. The involucre of 7. mollissima often splits on one side like a spathe, and is composed of three ovate-lanceolate segments, which are united one to the other at different levels, and which have everted edges. In 7. tomentosa, Lam., the involucre is regularly tubular, the con- stituent bracts are united two-thirds of the way up, and the free portions are broadly ovate-acute. 7. T. mixta, Juss., in Ann.

The arrangement above given is that adopted in my monograph in the Flora Brasiliensis. The disposition proposed by MM.

MASTERS’S CLASSIFIED LIST OF. PASSIFLORE®. 127 unanimity of opinion as to the name a particular variety should bear, or as to what species it should be ranged under. I have, therefore, adhered to my own arrangement, founded as it is in great measure on repeated examinations of culti- vated specimens. In addition to the foregoing species may here be cited the names of sundry garden varieties or synonyms. T. di ler Mae Mee | le a ia | Buchanani, Lemaire, Il.

Jamesoni, Mast., a native of Quito, may be mentioned as one of the very finest even in this remarkably handsome-flowered group. It is possible this species may be in the hands of Mr. Anderson Henry, as he received seeds of several kinds from the late Professor Jameson. In any case the attention of collectors should be directed to this plant, and, indeed, to the remaining species not yet known in gardens, and numbering about twenty in addition to those above enumerated. It is also probable that the less known regions of the Andes may yield other species at present quite unknown to science. The lovely T. insignis may be taken as a guarantee of this. This was introduced quite recently from Bolivia by Mr. Yarborough Greame, previously to which time the species was absolutely K 2 128 ROYAL HORTICULTURAL SOCIETY. unknown to botanists, as there are no specimens in the herbaria.

Kewens., iii., 308 (1789) ; Bot. Reg., t. 88. Messrs. Triana and Planchon, however, challenge the propriety of so doing, being of opinion that Aiton’s glauca (1789) is a synonym of Aublet’s stipulata (1775). As to the latter plant, the only material for an opinion is the plate in the Plante Guianens.

While admitting the accuracy of their observations on particular specimens, I may remark that there are so many transitional and intermediate forms con-_ necting the extremes, that it appears to me preferable, on scientific grounds, to treat the species in a broad comprehen- sive way. To follow the opposite course would almost necessitate the considering of every specimen in the herbaria or in gardens as a distinct species. The botanists in question lay great stress on the presence or absence of pubescence on the ovary and fruit respectively ; but from my examina- tion of the herbarium specimens, and of numerous culti- vated forms, I can by no means attach so much importance to this character as they do.

Quite recently, fresh specimens have been forwarded by Messrs. Rollisson, which differ somewhat from those originally examined. The plant is pubescent, or villose, rather than pilose ; the flower is of a rose-pink colour, not red- dish-violet, the flower-tube is sulcate and lobed at the 136 ROYAL HORTICULTURAL SOCIFTY, base, the sepals are 3-nerved, and spread horizontally. The membranous corona is slightly plicated, and the threads immediately above it are more slender than in the original specimen. The ovary is longitudinally ribbed. By a misprint the leaves are described as tri-lobed in the Flora Brasiliensis. The plant is very curious, and its position in the genus not free from doubt. It is nearly allied to P. reflexiflora.

Sa This is the large-fruited Passion-flower rendered so famous some years since from the exaggerated accounts published of it by a notorious impostor. Messrs. Triana & Planchon (Ann. Sc. Nat., 1873, tom. xvii., p. 147) are of opinion that my P. macrocarpais the same as the large-fruited variety of P, quadrangularis mentioned by Jacquin. I have already given my reasons for dissenting from this view, and can only now repeat my conviction formed after the repeated examination of dried 'and living forms, including one of 138 ROYAL HORTICULTURAL SOCIETY. Jacquin’s types, that P. quadrangularis with deeply-winged stems and oviform fruit, P. alata with narrowly-winged stems and obovoid or pyriform fruit, and P. macrocarpa with deeply winged stems and very large, oblong, obtuse, sulcate fruits (all three, moreover, differing materially one from the other in the arrangement and number of the parts of the corona)—are specifically distinct. With all deference to Messrs. Triana & Planchon, whose opinion is entitled to respectful consideration, I must still consider P. macro- carpa as totally distinct. My reasons for so doing are stated at length in Gard. Chron., 1869, 1012, and the plates in the Flora Brasiliensis above cited will show more clearly than words would do the great difference between the flowers of P. alata and P. macrocarpa. I have now repeatedly seen the three species as grown in English gardens side by side, and cannot doubt their distinctness. At Kew, in the Palm Stove, P. qguadrangularis and P. macrocarpa are grown side by side, and no one who sees the two in juxta-position in flower and fruit would confound them. The characters derived from the foliage, stipules, and wings of the stem are, it is true, less trustworthy. The question remains whether there is a large-fruited variety of P. quadrangularis, or whether Jacquin’s variety, sulcata, should be referred to P. macrocarpa. Messrs. Triana & Planchon think it possible that Jacquin may have confounded P. alata with P. guadrangularis, and that the true P. guadrangularis is what he calls the variety sulcata, But Jacquin’s description of the petiolar glands and of the fruit is that of P. guadrangularis, and not of P. alata. The type specimen of Jacquin in the British Museum does indeed bear out MM. Triana and Planchon’s opinion, so far as relates to the narrow wings to the stem; but the petiolar glands are six in number, and the nerves of the leaf _are not arranged as in P. alata. It must also be borne in mind that the plants in ques- tion have been cultivated for a long series of years over a wide range, and that seminal and hybrid varieties have in consequence been produced. 49.

Central America, Venezuela, &c. In addition to the preceding species, whose botanical history is more or less well known, there are several other forms named in gardens and garden-catalogues, some of which are probably selected seedling varieties, of well- known species, while others are known to be of hybrid origin. I give a list of these names, but without accepting any responsibility as to their correctness :— P. aculeata, Hort. I have no idea what this is. bo Ae P. albicans, Hort. This is probably a misprint for P. albida, Ker. x P. albo-nigra, Regel. Gart. Flora (1852), t. 8. Said to be a cross between P. alata and P. Raddiana. P. amabilis, Hort. ? This is said to be a hybrid between P. racemosa as the g and P. alata g. I have not seen it, unless it be the DR. MASTERS’S CLASSIFIED LIST OF PASSIFLORER. 145 same as the species of the same name. See ante, No. 50. x P. alato-cerulea, W. Mast. in Bot. Reg., 848. A hybrid between the species named, raised in the Can- terbury nurseries. ? P. angulatas Hort. Probably a misprint for P. alata. x Bijou. Said to be a hybrid between P. racemosa and P. Rad- diana. x P. Belottii; Hort., Regel. Gart. Flora (1852), 44; Gard. Mag. Bot., 1., 9. Said to be a cross between x JP. c@ruleo-racemosa and gad rangularis. | x P. Buonapartea, Hort. Probably a hybrid between P. alata and P. quadrangu- laris. | x P. cwruleo-racemosa, Sabine; Trans. Hort. Soe., iv., 9; Lodd. Cab., 573. A well-known hybrid between the two species above- named. In the list kindly forwarded me by Dr. Regel a variety of this (?) called Cleweriana is mentioned. P. ceruleo-Kermesina, Probably across between P. carulea and P. Raddiana. P. cardinalis: Hort. Laurentius. P. chinensis, Hort. Is probably a form of P. ce@rulea. x P. Colvillei, Sweet Brit. Fl. G., ii., 126. Said to be ahybrid between P. caerulea 8 and P. inear- nata 2. See ante, No. 71. x P. Decaisneana, Flore des Serres, viii., 848 ; Revue Horticole, 1855, 15. Said to be a hybrid between P. quadrangularis and P. alata. | P. fragrans, Hort. Said to be = P. Middletoniana. P. Countess Gigliucci ?. P. Hartwiesiana, Hort. Rollison, is probably a seedling variety of P. cerulea, with white flowers. P. helleborifolia, Wadlis. Of this I have seen a sketch by its discoverer. It is apparently very near to P. pedata, but may be dis- tinct. ; 146 ROYAL HORTICULTURAL SOCIETY. P. hircina, Hort. — P. fetida. P. Hulletti, Hort. = P. macrocarpa, Mast. x P. hybrida floribunda, Hort. Apparently a cross between P. cerulea and P. Raddiana. P. Imperatrice Eugénie. Illustr. Horticole, 1858, 175. Apparently a cross between P. c@rulea and P. quadran- gularis or P. alata. x P. Innesii, Mast. in Gard. Chron., 1870, 891. A cross between P. alata @ and P. macrocarpa Co. P. Karsteniana. ? = P. bryoniocdes. P. Lamberti, Hort. x P. Lawsoniana, Mast. in Gard. Chron., 1868, 1288. A cross between racemosa g and alata 2. . x P. Lemicheziana. P. Loudoni, Hort. I have met with different forms under this name, but I have reason to think the original P. Zoudoni was a cross between P. Raddiana and P. racemosa. P. maculata, Hort. ? x P. Madonna. Said to be a cross between P. racemosa and P. Buona- partea, P. marmorea, Hort. Linden = Ophiocaulon cissampeloides. Mast. P. Mayana. A form of cerulea probably. x P. Munroii, Mast. in Gard. Chron., 1868, 1288. A cross between cerulea ¢ and alata 9. x P. Count Nesselrode. P. patula, Hort. ? P. semiorbicularis, Hort. Petrop., said to be Brazilian. P. tripartita, Hort. ? P. ulmifolia, Hort. ? P. Comte de Woronzoff. Said to be a form of P. Raddiana. INDEX OF NAMES.

Report on Onions Grown at Chiswick for Trial by the Fruit and Vegetable Committee of the Royal Horticultural Society, 1875. By A. F. Barron. Tue seed for this trial was furnished by the following gentlemen, viz. :—Messrs. Barr & Sugden ; Messrs. Carter & Co. ; Messrs. Cut- bush & Son; Messrs. Benary, Erfurt; Messrs. Nutting & Son; Messrs. Sutton & Sons; Messrs. Veitch & Sons; Messrs. Vilmorin et Cie., Paris; Messrs. Harrison & Sons; Messrs. Stuart & Mein; Messrs. Piccirillo; Messrs. Hovey & Co., Boston ; Mr. Dancer; Mr. J. Perry; Mr. A. Parsons; Mr. R. Dean. The seed was sown on March 16th in well-pulverised, moderately rich soil, which had the previous season been well manured for Celery. The season was on the whole favourable for the growth of Onions, so that the trial was so far of a very satisfactory character. Altogether 155 samples were sown, representing ninety-eight different names, of which number twenty are here described as quite distinct. The report only extends to those varieties which have been proved to be well adapted for spring sowing and early autumn or winter use, the remainder of the Tripoli and Silver-skinned sections being again submitted for trial as autumn-sown Onions. 1. White Spanish. Synonyms.—Banbury (Perry); Banbury Improved; Nuneham Park; Improved Nuneham Park; Reading; Improved Reading ; Naseby Mammoth (Carter & Co.) ; Oxonian Prize (Nutting & Son) ; Cutbush’s A 1 (Cutbush & Sons); Portugal; Cantello’s Prize (Waite, Burnell & Co.) This variety is the one most generally cultivated. The plant is of free growth, the neck of medium size, and ripens off early and well. The bulbs are large, a fair-sized specimen measuring about 12 inches in circumference, and from 2 to 23 inches in thickness. . The shape is flattened, the base broad, flat, frequently a little hollowed and uneven, somewhat globular towards the stalk in the -best forms. ‘ Skin pale straw, falling-off readily and exposing the pale greenish-yellow outer flesh. The flesh itself is firm and solid, _almost white, and of excellent quality. This variety keeps gene- rally in good condition up to the month of March. The Banbury and Nuneham Park forms were the most improved. P 196 ROYAL HORTICULTURAL SOCIETY. 2. Large Straw-coloured (Vilmorin). Synonym.—Yellow Flat (Hovey & Co.) This is only to be distinguished from the White Spanish by the darker colouring of the outer skins. * Yellow Lescure (Vilmorin) ; Yellow Cambrai (Vilmorin). These were considered very spurious stocks of the Large Straw- coloured. 3. White Globe. Plant of free growth, forming in general a small neck; ripens off early and well. The bulbs are of medium size, from 9 to 10 inches in circumference, and about 23 inches in depth. The shape is somewhat globular or obovate, with a finely rounded high crown. The skin is pale straw like the White Spanish, and it is, indeed, similar to that variety in every other respect but its more globular form. It is an excellent keeping sort, and much esteemed. White Intermediate Oscar (Cutbush & Sons). These are mixed and indifferent stocks of White Globe and White Spanish. 4. Trebons (Vilmorin et Cie. ; Stuart & Mein). Plant of free growth, but somewhat tender, succeeding best in a warm season. Neck somewhat gross. The bulbs are of very large size—about 13 inches in circumference, and from 3 to 34 inches in depth. The shape is obovate, the base somewhat broad and flat, whilst the top tapers more to the stalk or neck. The skin is pale straw, and peels off readily like the White Spanish. The flesh is pale and rather soft in texture, but of mild and excellent quality. This is a very large and handsome Onion for early autumn use. It does not keep well, and generally begins to shoot before Christ- mas. It bears a close resemblance to the imported Spanish Onions. 5. Yellow Danvers (Hovey & Co. ; Vilmorin et Cie. ; Carter & Co.) Synonym.—Danvers Yellow. This is a very fine and distinct Onion. The plant is of free growth, the top slender, of a rather pale green colour, and with a very fine slender neck, so that it ripens off well. The bulbs are of MR. BARRON’S REPORT ON ONIONS. 197 medium but very even and regular size, from 10 to 11 inches in circumference, and about 24 inches in depth. The shape is roundish globular, very regular, with a small base and a small neck. The skin is of a dark straw colour, the outer coating peeling off freely, but not exposing the flesh; the inner coating remaining firm, giving the Onion a very neat, clean appearance. The fleshis very firm and solid throughout, and of fine quality. A splendid keeping variety. New German (Veitch & Sons). This bears a close resemblance to Danvers Yellow, but scarcely appears to keep so well. 6. Brown Globe. Synonym.—James'’s Keeping. This is of the same character as the White Globe, but having darker or reddish-brown skins ; some are pale-fleshed throughout ; others, these being the darker-skinned, have a slight shading of red as an outside coating of the various layers, as in the Red varie- ties. It is an excellent keeping variety, and much esteemed. The James’s Keeping of some is more flattened near the crown, forming a sort of shoulder to the stalk, and of others again it is similar to the Pear-shaped. Magnum Bonum (A. Parsons) is a very fine selection of the Brown Globe. Brown Intermediate ; Bedfordshire Champion. These are mixed stocks of Brown and White Globe. 7. Pear-shaped. Synonym.—Pyriforme. - This is allied to the Globe section, and may he described as an elongated form of that variety. The plant is of free growth, the great majority producing very thick necks with very little bulb, so that they do not ripen off well. The true form is like that ofa long Pear, tapering mostly towards the stalk, from 7 to 8 inches in circumference, and from 4 to 5 inches in depth or height. The skin is of a dark-reddish brown, and falls off readily. The flesh is moderately firm and solid, but it is not a very good keeping sort, and its shape does not recommend it. A good selection of this is sometimes sent out as James’s Keeping. Pp 2 198 ROYAL HORTICULTURAL SOCIETY. 8. Deptford. Synonyms. —Brown Spanish ; Improved Brown Spanish ; Stras- burg; Strasburg Dutch; Pale Red Niorte; Light Red Stras- burg. Plant of free growth and very hardy, forming a small neck and ripening early. The bulbs are of medium size, flattened or oblate, ‘of pretty even and regular form. The skin is of a dark reddish- brown colour. The flesh firm, solid, tinged with red. An excel- lent keeping variety. 9. French Strasburg. Synonym.—Pale Red St. Brieux. This is distinct from the Deptford or English Strasburg. The bulbs are smaller, of very uneven shape, and frequently split open into several crowns. They are of a dull reddish colour. Alto- gether very inferior varieties of the Deptford class. 10. Deep Blood Red. Plant of free and hardy growth. Bulbs of medium or rather small size, flattened or oblate, and generally of very even and regular form. The outer skin is of a dull red colour; the inner coating of a deep glossy red. The flesh itself is pure white, it being only the outside coating of the various layers that are coloured, and these become paler towards the centre. It is very firm and solid throughout. This is the strongest flavoured Onion, and the latest keeper. . On these accounts it is a valued variety. Blood Red. This is simply a paler-skinned variety of the preceding, and the most common, 11. Wethersfield Red (Hovey & Co.; Carter & Co. ; Benary & Son). Synonym.—Bright Red Mezieres (Vilmorin). Piant of free and robust growth. The neck small, ripens off freely. Bulbs large, flattened or oblate, very even and regularly formed, about 12 inches in circumference and 2 inches in depth. The outer skin is of a light dull red colour, and peels off freely ; the inner coating being light purplish, shading greatly from the crown to the base, where it is very pale. The flesh is pure white, the outer surface of the coating only being coloured. It is very firm, solid, and of mild and excellent quality, and keeps well. A MR. BARRON’S REPORT ON ONIONS. 199 remarkably fine and handsome Onion from America. The finest type of Red Onion. 12. Early Red (Hovey & Co.) This is a rather early red variety. The bulbs are of medium size, flat, of a very dull red colour. The flesh is firm and solid, and of good quality. It showed a tendency to the production of several crowns, which burst and spoil the bulbs, and prevent them keeping. 13. Zwo-bladed. This name is given to denote its peculiarity of only producing two blades or leaves. These form small bulbs very early in the ‘season, and soon ripen off; a great majority, however, grow into larger bulbs, and these have the ordinary number of leaves. The true two-leaved type has small roundish bulbs about an inch in diameter. The skin is of a dull yellowish brown colour; the flesh greenish white, and frequently a little coloured, They are very firm and solid, and keep well. The small size makes it useful for pickling purposes. 14. Teneriffe (Benary & Son). This greatly resembled in appearance the smaller types of the Two-bladed, 15. Silver-skin (Nutting & Son). Synonyms.—Silver-skin Pickling (Veitch) ; Early White Silver- skinned (Benary & Son) ; White pata Early Hard Dutch (Vilmorin et Cie.) The bulbs are of medium size, roundish oblate ; a great many are apt to split open. The outer skin is pure white or silvery, ’ peeling off freely and exposing the next coating, which is white with green veinings. The flesh is pure white, exceedingly firm and solid. Keeps remarkably well, and is useful to those who prefer very white onions. This is quite distinct from the Paris Silver-skin, which does not keep well. 16. Queen. Synonyms.—New Queen ; Piccirillo’s New Queen. This is a very small and very early variety of the Silver-skinned section. It forms bulbs almost as quickly as a Radish, and has rarely more than two or three leaves. They were fully grown 200 ROYAL HORTICULTURAL SOCIETY. last season by the 1st of June, about fifteen days earlier than the White Italian Tripoli, which variety in the late trial it most nearly resembled. Many large and later-growing examples were observed in each sample, which, if the seed was not mixed, implies a tendency to deterioration. In this, as in other respects it exactly resembles the Nocera as introduced from Italy about thirty years ago, and the Florence White of earlier date. N.B.—AII the section of Silver-skinned Onions, including the Queen, White Italian Tripoli, Marzajola, Nocera, Paris Silver- skin, Early White Naples, and White Lisbon, also the Giant Tripoli section, including the Giant Rocca, Red Sallow, Madeira, &c., which are found valueless as spring-sown varieties, will form the subject of a separate report when their respective merits have been tested as autumn or winter-sown Onions. 17. Potato Onion. Synonym.—Underground Onion. This is not propagated by seeds. The small bulbs are planted in the ground like Shallots, and around these a number of new bulbs are produced. These bulbs are of average size, of somewhat irregular shape; the skin reddish brown, hanging very loosely. The flesh is tolerably firm and solid, and of fair quality. It does not keep well, but is useful for procuring an early supply of Onions. 18. Egyptian. Synonyms.—Kgyptian Bulbiferous ; Tree Onion; Garden Rocam- bole. This variety when planted throws up a stem on which, instead of flowers, small bulbs are produced of about the size of small marbles, which are very excellent for pickling. It is propagated by planting these bulbules (the largest of which will bear bulbs the same season), or by the bulbs which are formed in the ground, and which have not formed stems. 19. American Perennial Tree, or Top Onion (Carter & Co.) This produces small bulbules in the same manner as the Egyptian Bulbiferous, but of a much smaller and inferior character. No bulbs are formed in the ground. The plant is perennial ; the roots are long and fibrous. MR. BARRON’S REPORT ON CELEBIES. 201 20. Welsh. 4 _ Of this there are two varieties, the Red and the Green. The plant is an herbaceous perennial, and forms no bulbs; the roots are long and fibrous. The green tops or leaves only are used. It may be propagated by seed or by division of the roots. XXXVII. Report on Celeries Grown for Trial by the Fruit and Vegetable Committee of the Royal Horticultural Society at Chiswick, 1874-5. By A. F. Barron. Tue seed for this trial was presented by Messrs. Carter & Co. ; Messrs. Barr & Sugden ; Messrs. Minier, Nash, & Nash; Messrs. Harrison & Sons; Messrs. Osborn & Sons; Messrs. Stuart & Mein ; Messrs. Veitch & Sons ; Messrs. Vilmorin et Cie. ; Samuel Simpson, Esq.; Mr. R. Dean; Mr. A. Parsons. There were forty-seven reputed varieties received, of which twenty-three were red and twenty-four white. These the Com- mittee by the detection of numerous synonyms reduced to twenty— viz., seven red varieties and thirteen white, which have been decided to be distinct. The seed was sown early in March in heat, and the plants pricked-off and planted-out early in June in single trenches, and treated after the ordinary manner. The plants were frequently examined by the Committee whilst growing, and again when fully grown, and a portion of each sort was left to test their capabilities of standing the winter. The season of 1874 was a particularly favourable one for the growth of Celeries, so that the trial was a satisfactory one. I. Rep VARIETIES. 1. Manchester Red.

REPORT ON PELARGONIUMS GROWN AT CHISWICK IN 1876. 251 XLY. Report on the Double-Flowered Varieties of Zonal Pelar- gonium Grown for Trial by the Floral Committee of the Royal Horticultural Society at Chiswick.

Henderson & Son; Paul & Son; Rollisson & Sons, Veitch & Sons; Alegatiére ; Cannell ; Fraser ; Laxton ; Laing; Lemoine ; Paul ; Sisley ; Smith ; Turner ; Williams. They were grown in 9-inch pots and flowered under glass. A good bloom was secured on most of the varieties by the beginning of July, when they were inspected by the Committee, and again in September. The trial was in all respects a satisfactory one. For easy identification they have been grouped into the following classes, according to the various shades of colour of the flowers :— 1. Scarlet. 8. Magenta-Rose. 2. Scarlet shaded with Ma- 6. Pale-Pink. genta. 10. Very pale Salmon. 3. Magenta-Scarlet. 11. Pale Salmon, 4. Purplish-Scarlet. 12, Salmon. 5, Orange-Scarlet. 13. Oculate. 6. Cerise. 14. White. 7. Rose-Pink. And the Pompon-flowered of several coloured, which are so distinct in character as to form a separate group. A subdivision of these classes has also been adopted, in regard to habit, flowering, &c., there being at least two very distinct classes, viz. :— 1. Gross-habittype, Madame Lemoine, of strong gross growth ; the leaves large and broad; moderate flowering. 2. Free-habit type, ordinary zonal, of free medium growth, &c. ; very free and continuous flowering, like the ordinary single zonal Pelargonium. ** denotes the varieties which have received certificates.
