SUB-ALPINE PLANTS OR FLOWERS OF THE SWISS WOODS AND MEADOWS BY H. STUART THOMPSON, F.L.S. / ) AUTHOR OF ALPINE PLANTS OF EUROPE WITH 33 COLOURED PLATES (168 FIGURES) BY GEORGE FLEMVVELL AUTHOR OF "ALPINE FLOWERS AND GARDENS," ETC. LONDON GEORGE ROUTLEDGE & SONS, LIMITED NEW YORK : E. P. DUTTON & CO. 1912 HEPATICA " MOST welcome, while the meagre East Rebuffs the Spring, is thy brave face, Dear nursling of the Alps, and least Of all the windflower race. " Ere crocus-blades defend their gold, Or woods are with thy kinsfolk white, Thou beckonest thy comrades bold, Snowdrop and Aconite. " Not Winter's tyranny can blanch Thy cheek, or bruise thy buds of silk ; Hast thou not heard the avalanche And quaffed the glacier-milk ? " So to his face thou dost profess Thy faith in Spring, and dost outrun Thy very leaves in eagerness To hail the insurgent sun." ALFRED HAYES in The Cup of Quietness. UANDSCAPB •73- PREFACE IT is quite natural that most of the books on Alpine plants have dealt chiefly with the higher zone of vegetation, and that consequently the flowers of the sub-alpine woods and meadows have been somewhat neglected. Therefore it is believed there is room for a book descriptive of the plants of the lower mountains. In the first chapter it is explained that owing to overlapping, a large number of species characteristic of the sub-alpine regions are also found in the higher pastures ; and that many others, of which not a few are British plants, descend to the plains. No book on the subject would be at all representative if both series were not included. When not otherwise stated, every plant described is believed to be perennial. In the case of a few species short cultural notes are given ; while there is a general chapter on the culti- vation of Alpine plants. The heights given in the text refer more especially to the Swiss Alps, though sometimes I have given the approximate altitudinal limits of certain species as observed by myself in other mountain ranges. Naturally in Britain, Scandinavia, etc., most of the Alpine plants common to those countries and Switzerland flourish at much lower elevations. The terms " Eastern," " Central," and " Western " Alps need some slight explanation. These divisions are roughly those adopted both in the late John Ball's classic Alpine Guide, and in Mr. Coolidge's The Alps in Nature and History (1908). Those two authorities have defined the WESTERN ALPS as extending from the Col de Tenda to the Simplon Pass in southern Switzerland. The Col de Tenda separates the Mari- time Alps from the Ligurian Mountains, and carries the high road from Nice to Cuneo and Turin. Thus the Western Alps SGI viii SUB-ALPINE PLANTS are chiefly in France and Italy, but they also comprise that part of Switzerland which is south of the Rhone. The CENTRAL ALPS include the greater part of Switzerland, north and east of the Simplon ; the small portion of Tyrol west of the Reschen Scheideck Pass and the bit of Alpine Lom- bardy to the north. The EASTERN ALPS comprise the rest of the Alpine ranges to the east of the Reschen Scheideck and the Stelvio Passes. They are wholly Austrian and Italian', except for the limestone hills of Bavaria in the north. Among the many books and pamphlets consulted in the preparation of this work I must especially mention the help derived from the Flore de la Suisse by Messrs. Schinz and Wilczek, Mons. Coste's Flore de la France, and Bentham's Hand- book of the British Flora, which has been especially useful in framing synopses of the characters of families and genera. My best thanks are due to my friend Mr. George Flemwell, the author of Alpine Flowers and Gardens, etc., for painting a beautiful series of flowers, which he has done in the course of a busy and eventful year, not undisturbed by illness. These drawings, though reduced in size in the plates, are remarkable for their accuracy of form and colour and for their artistic merit. They were made in many cases from specimens growing in the neighbourhood of Le Planet, above Argentiere in Haute- Savoie. The Swiss frontier is only a few miles distant. I am indebted to Messrs. Methuen and Co. for permission to reprint the charming poem entitled Hepatica, written by my friend Mr. Alfred Hayes. Finally I must not omit to thank Professor Seward and Dr. C. E. Moss for their kindness in allow- ing me to freely consult the Library and Herbarium of the Cambridge Botany School. H. STUART THOMPSON. CAMBRIDGE, May, 1912.

It was stated that it was impossible to give an exact definition of the term ' sub-alpine,' but it could be taken to be the zone from about 3000 feet, where the vine ceases to be cultivated, to about 5000 feet. But it should be clearly understood that any such limitation is purely arbitrary, and that the expressions Alpine and sub-alpine are often used in a very general sense. The vegetation of one valley of say 5000 feet above the sea may be far more Alpine in character than that of another of about the same height in a district not very remote. Nor is it always possible to do as that great Alpinist and student of the Alpine flora, the late John Ball,1 did. He called the Sub- Alpine Region the Region of Coniferous trees ; and the lower Mountain Region the Region of Deciduous trees (whose upper limit often rises to 5000 feet on the southern slopes). But beech forests are also, in certain districts, a great feature of the sub-alpine zone. The very fact that the forest region, and especially the pine forest region, varies so much in different countries of Europe, and also in quite limited districts, prevents such a basis of calculation from being quite satisfactory, though otherwise it has much to commend it. In Switzerland the Lowland region comprises the plains and the 1 "Climate and Vegetation of the Alps," in the General Introduction to the Alpine Guide. B 2 SUB-ALPINE PLANTS low hills in the north and west. The flora is very similar to that of temperate Northern and Western Europe, including most of France, Germany, Belgium, and the British Isles. But in addition one finds in the Swiss plains and warm valleys a distinct admixture of Southern plants of Mediterranean source. Among them may be mentioned Astragalus Onobrychis, A. monspessulanus, Trigonella monspeliaca, and Centaurea crupina. In the Rhone Valley about Sion, there is a remarkable mixture of Southern plants, such as Buffonia macrosperma, Iris virescens, Tulipa australis, and Ephedra helvetica, which have ascended the great river basin from the Mediterranean, together with sub-alpines which have descended the mountain-sides. It is remarkable how few species are purely sub-alpine, in that they do not grow in the lowlands or in the Alpine region. The following might perhaps be chosen as typical sub-alpines, character- istic of that actual zone. Actcea spicata, Dentaria digitata, Lunaria rediviva, Cytisus alpinus, Ononis rotundifolia, Saxifraga cuneifolia, Sambucus racemosa, Prenanthes purpurea, Centaurea montana, Veronica urticcefolia, Lister a cor data, Streptopus amplexifolius, and Lilium Martagon. Among the 850 species described in this volume there are very few, if any, which do not grow in what is commonly understood as the sub-alpine region in Central Europe, if not in Switzerland. But there is so much overlapping that a very large number of these are also found in the Alpine zone, and a considerable number descend to the lowlands. A fair proportion of the Swiss sub-alpines are British plants. If these Alpine and lowland plants were omitted from a book descriptive of what may be called, with approximate accuracy, the more beautiful and interesting flowers of the Swiss woods and meadows, it would be altogether unrepresentative and misleading. Many Alpine plants have a very great vertical range of altitude ; just as others may be confined to quite a narrow zone. Among those species which the writer has noticed growing in the Alps through the greatest vertical range — a range of at least 7000 feet in some cases — are the following : Arabis alpina, Draba aizoides, Cerastium arvense, Lotus corniculatus (up to 9000 feet several times), Dry as octopetala, Potentilla Tormentilla (this ubiquitous plant reaches 8200 feet on the Col du Galibier), Saxifraga stellaris, S. aizo'ides, S. Aizoon, Sempervivum arachnoideum, Antennaria dioica, Leucanthemum vulgare, Campanula pusilla, Primula farinosa, P. viscosa Vill., Gentiana verna, G. ciliata, Calamintha alpina, Linaria alpina, Thymus Serpyllum (up to 9000 feet), Daphne Mezereum, Plantago alpina, Polygonum viviparum, P. aviculare, Euphorbia Cyparissias, Triglochin palustre (found at sea -level in England, in the plains of Switzerland, and up to 8250 feet in Dauphiny), Juncus bufonius, Scirpus compressus, S. cczspitosus, SUB-ALPINE PLANTS AND WHERE THEY GROW 3 several species of Carex, such grasses as Poa alpina, P. bulbosa, Agrostis alba, Phleum alpinum, Deschampsia ccespitosa, Festuca ovina and Nardus stricta. He has also observed the following ferns with a range of from about 5800 to 6800 feet in the Alps, viz. : Cystopteris fragilis (up to 8500 feet), Dryopteris Filix mas, D. spinulosa, Asplenium viride (up to 8800 feet), A. Trichomanes, Polypodium vulgar e, and Botrychium Lunaria (up to 8400 feet). In comparing the flora of Switzerland with that of the British Isles, the most apparent difference is the absence of the maritime element from that of the former country. Even the Sea-thrift (Armeria maritima) which sometimes grows on hill- tops in England, Scotland, and Ireland, is absent from Switzerland, and its place is taken by the larger and more handsome Armeria alpina. But there are one or two maritime plants, such as the Yellow Horned Poppy (Glaucium ftavum), which find a suitable home on the sandy shores of the Lake of Neuchatel. To students of ecology, or plant associations, and to those occupied with the geographical distribution of plants, the absence of certain species from a given area is no less interesting than the presence of others. Let us therefore mention a few types (other than maritime) of plants found in the British Isles which do not occur at all in Switzerland. In the first place we have a few High- land species, such as Saxifraga nivalis and Primula scotica, which do not get so far south as the European Alps. In Ireland there are one or two North American plants, such as Spiranthes Romanzoffiana and Sisyrinchium augustifolium, which occur nowhere else in Europe. Owing to the moisture of our climate and the mildness of our winters, we have various Lusitanian species, characteristic of Portugal and the south-west of Europe, which extend their range much further north in these islands, especially in Cornwall, Devon, Dorset, and the south-west of Ireland, than they do elsewhere. Among them are several Heaths, such as Erica vagans (it is found in very few places in Switzerland), Erica ciliaris, and the Conne- mara Heath (Dabeocia cantabrica). The common Bell Heather (E. cinerea) is not found at all in Switzerland, and in only one place in Germany, above Bonn ; nor is Erica tetralix found in Switzerland. In fact, with the rare exception of E. vagans, Erica carnea, and Calluna (Ling) are the only Heaths in Switzerland. Other western species found in England and Ireland, but not in Switzerland, are the little Butterwort (Pinguicula lusitanica), the tiny yellow Cicendia filiformis, Cotyledon umbilicus with its peltate, fleshy leaves, and Iris fcetidissima, whose capsules, with bright orange- vermilion seeds adorn many of our Lias woods in autumn. We have also quite a number of bog or aquatic plants which do not occur in Switzerland. They include the Ivy-leaved Campanula, (Wahlenbergia hederacea), the Bog Pimpernel (Anagallis tenella), 4 SUB-ALPINE PLANTS the Marsh St. John's-wort (Hypericum elodes) and the Bog Myrtle (Myrica gale). The Bog Myrtle is distinctly an Arctic and Western European species, and so is^the Bog Asphodel (Narthecium ossi- fragum]. Neither of the two British Lobelias (L. urens and L. Dortmanna) is found in Switzerland. The former is purely Western European in its distribution, and the latter is more northern. To sum up the chief differences between the Swiss lowland vegetation and that of great Britain or Ireland : in Switzerland there are no hills or commons covered with Bell Heather and Erica tetralix ; no wet, sandy moors, such as those in Dorset, made picturesque with the same two heaths mingled with the beautiful Erica ciliaris and Bog Myrtle, the brilliant yellow spikes of Bog Asphodel turning coral-red in September, the little yellow Cicendia, the pale Pinguicula lusitanica, and the curious Hypericum elodes. In Switzerland the Gorse (Ulex europ&us) and the Broom (Saro- thamnus scoparius) are hardly even seen, the former being native only near San Bernardo in Tessin ; on her banks and hillsides there are no Purple Foxgloves, but two less handsome yellow ones ; and in her lowland woods and hedges the bright blue Scilla bifolia takes the place in spring of our wild Hyacinths. Excluding sub-species and varieties, there are at least 2540 species of flowering plants and ferns in Switzerland ; or perhaps six hundred more than in the British Isles, notwithstanding their long coast- line and great variety of geological formation. And yet we have very much to be thankful for — we have Alpine and Arctic plants in the north, on some of the highest mountains further south, and in Ireland ; we have, as already stated, quite a number of Lusitanian and Atlantic plants in the south-west of England and Ireland. Then there is a large Germanic element chiefly in the east of Eng- land ; a most interesting maritime flora, with a few species from the Mediterranean ; and many others which come under either the British, English, or Scottish type according to H. C. Watson's types of distribution. Indeed, there can be few countries in the world with so many interesting types of vegetation as the British Isles. Insular floras are almost without exception interesting, and that of our own Islands is of special interest, and furnishes some of the greatest surprises. One of the Continental botanists who took part last year in the Phytogeographical excursion in the British Isles wrote1: "However much we have seen in different countries, we still found many peculiarities in the British vegeta- tion which are not seen elsewhere, and many features which are as striking and interesting as any we have ever met with." Unlike most islands, however, and especially those of the Medi- terranean, the British Isles can boast of extremely few endemic species. The peculiarities of many high Alpine plants are not so noticeable 1 The New Phytologist, January, 1912, p. 28. SUB-ALPINE PLANTS AND WHERE THEY GROW 5 in the sub-alpines. It will be remembered that most of the high pasture and rock plants are of small stature, often growing in tufts, mats, or cushions ; with small leaves arranged in flat rosettes pressed against the ground. The roots are often very long, some- times penetrating several feet into the ground so as to absorb all the moisture and nutriment possible, and also to prevent them from being blown away bodily by the high winds so frequent in the Alps. Many of them are prevented from being dried up through too rapid transpiration by developing a copious covering of hairs or woolly tomentum, as, e.g., in Hieracium villosum and in Edelweiss. Most conspicuous of all is the abundance of blossom and the brilliant colour of many of the Alpine flowers, particularly of the blues, reds, and purples. Some of these characteristics are less noticeable in the plants of the mountain woods and meadows, for the simple reason that there is no great cause for their existence ; for the climate is less severe and the winds less high. But, though it is supposed that the extreme brilliance of the light at high altitudes has a great effect upon the colouring of the flowers, yet in that particular, and especially in the abundance of blossom, many of the sub-alpines can well hold their own. The rapidity with which they blossom is another point in common. A large number of Alpine plants are specially constructed with a view to flowrering at the earliest possible opportunity, just as are the Arctic species. The shortness of the summer is naturally the chief reason which has led to such peculiarities. After the flowering stage is more or less over, the seeds have to ripen. Time must then be allowed for their dispersal under suitable conditions, and finally for their getting a good start before they are embedded in the first snows of winter. Most summer visitors to the Alps have noticed the snow melting from the highest pastures and exposing a sodden, brown sward. They have seen the Crocuses and Soldanellas flowering at the very edge of the melting snow, and sometimes pushing their blossoms through it ; but they may not have kept an eye on those sodden patches of snow-freed pasture during the next week or two. Had they done so, they would have seen a veritable transformation, so rapidly does the grass get green and bespangled with flowers of every shade and colour. It is the same with the meadows lower down ; but to see this it is necessary to visit Switzerland in May. Towards the end of April the snow has usually disappeared from the Alpine meadows ; and, though this is a peculiarly disagreeable season, with very little green grass to be seen, it is astonishing how soon the grass grows and the flowers appear. The meadow flowers are, for the most part, distinct from 'those which predominate in the upper pasturesj and they are distinct from those of the woods. The meadows usually occupy the more or less level portion of 6 SUB-ALPINE PLANTS Alpine valleys, and the pine forests descend on either side to meet them ; though in some valleys cliffs and steep rocky slopes take the place of the forests. The pastures, ' Alps/ or Alpen, are above the forest zone. In most communes the meadows are usually owned privately, but the pastures are held in common by the inhabitants of the villages, and each burgher has the right of grazing his cows on certain alpen. The meadows are very rich, for the soil contains much humus, or decayed organic matter, and fertilising deposits are also brought down by the numerous little rivulets which descend the slopes, and by the central glacier stream which usually flows through the valley. In addition to such natural irrigation, the peasants manure their land well, so that every season they get two crops of grass, while occasionally late in autumn men and women may be seen laboriously gathering in a third crop, though this is usually very scanty. The cattle are not often allowed on the meadows in spring, because the grass is more valuable when converted into hay. They are sent up to the lower pastures, and, as the summer advances, are gradually driven to the highest 'Alps.' If the higher pastures are ever mown, it is as autumn approaches. When once the meadows have yielded their first crop of hay, which is usually at the end of June or the first week of July, or if by chance the cattle should have had access to them, their great glory has departed. For though some plants quickly spring up again — Geranium sylvaticum sometimes flowers within a week — their chief charm has gone. The second crop is never so tall, nor often so full of blossom, and many of the plants have a branched, stunted appearance. Compared with an English meadow, the dense vegetation of these Swiss meadows consists not so much in true grasses as in other flowering plants. Probably the periodic manuring, and frequent cutting with the scythe tend to promote a dense growth of coarser plants at the expense of the finer grasses. Therefore we find great masses of pink Bistort (Polygonum Bistorta), of blue Centaurea montana, of mauve or purple Geranium sylvaticum, and many other handsome plants. We also find a number of marsh plants, for these meadows are often little more than peat marshes, and probably few of them have been drained with pipes, such as is the custom in England. Among the more important marsh plants frequent in -the mejadows are : Ranunculus aconiti- folius, the Globe-flower f(Trollius europczus), Primula farinosa, certain species of Pedicularis, Orchis maculata, 0. latifolia, Gymnadenia conopsea, and G. odoratissima. Many flowers of the Alpine meadows are ordinary British plants. In addition to those already mentioned and to the true grasses we often find such common species as the Buttercups (Ranunculus acris and R. bulbosus), the Ox-eye Daisy (Chrysanthemum Leucan- SUB-ALPINE PLANTS AND WHERE THEY GROW 7 themum), Bladder Campion (Silene inflata), Ragged Robin (Lychnis Flos cuculi), and, in autumn, Colchicum autumnale. Among Alpine meadow plants not, or in one or two cases very rarely, occurring in British meadows, there is a large number which especially tend to give such a wonderful colouring to the scene. The following are but a handful : Campanula rhomboidalis in sheets of azure blue ; the Rampions (Phyteuma orbiculare, P. betonicce- folium, and P. spicatum) ; Salvia pratensis in every shade of mauve and purple ; the goatsbeard or Tragopogon ; Yellow-rattle (Rhinan- thus) of several kinds ; various large Hawkweeds, and particularly the pale yellow Hypochceris uniflora ; Biscutella l&vigata, with its disc-shaped seed-vessels ; pink, red, and yellow species of Pedi- cularis ; and the beautiful Astrantia major. Among the most handsome of the Monocotyledons are various Orchids, St. Bruno's Lily (Paradisia Liliastrum), Anthericum Liliago, and the madder- red Lilium Martagon. In the drier portions of many sub-alpine meadows are found Cerastium arvense, Potentilla aurea, Saponaria ocymoides, the mauve Gentiana campestris, the rich purple Calamintha alpina, and the magenta Centaur ea uni flora, whose plumose involucral bracts form a curious feathery ball when in bud. Gentiana verna and G. utriculosa sometimes make sheets of blue in the damper parts of a field, but the large Gentiana excisa does not often grow in the meadows proper, but, like the Anemone sulphur ea, prefers the lower pastures skirting the forest. There is hardly a meadow without some huge boulders here and there. They may be partly screened by a growth of the lovely Rosa alpina ; and the rocks themselves usually afford shelter to patches of Sempervivum, Sedum, or Saxifrage. If the great yellow Gentian (G. lutea) or Veratrum album with similar foliage grows in the meadows, these bitter or poisonous plants are always left by the mowers, just as they are avoided by the cows on the steep pastures where they are more abundant than in the meadows themselves. It may seem quite unnecessary to specially mention any large stretches of fine Alpine meadows, for they are to be found almost everywhere in the Alps. But in Switzerland it would be difficult to come across a more magnificent expanse of meadow land refulgent with sub-alpine flowers of every kind and colour than in Val Ferret, above Orsieres, in Valais. This paradise of flowers, backed by stupendous mountains, is within easy reach of Lac Champex, now one of the most popular Alpine resorts. On the steep descent from Champex to Val Ferret can be found many species which delight in sun-baked, shaly slopes, such as those which lead to the village of Pras-de-Fort. The Jura mountains are much more wooded than the Swiss Alps. They also afford very excellent opportunities for collecting and 8 SUB-ALPINE PLANTS studying both the plants of the sub-alpine woods and meadows and many of the higher Alpines, which prefer limestone soil. The Jura has the double advantage of being a little nearer home and less crowded by visitors than the Bernese Oberland and the valleys south of the Rhone. The Flore du Jura, by C. H. Godet, published in 1853, gives an ample description! covering 870 pages, of all the flowering plants and ferns of this delightful mountain range. The sylvan flora of the calcareous Jura chain is particularly in- teresting. We have already observed that the Alpine forest flora is, for the most part, quite different from that of the meadows or the pastures. We have also noticed that the Coniferous forests extend upward to a height which varies considerably according to local circum- stances. As a general rule, in Switzerland the upper limit of the forests is from 6000 to 7300 feet, or some 2000 feet or more below the line of perpetual snow. The pine forest zone may be anything from 1000 to 2000 feet in vertical height, and the lower limit is frequently between 4000 and 5000 feet above the sea. At that height the Beech is replaced by the Spruce (Picea excelsa) and Larch (Larix europcea). At a somewhat higher level the Mountain Pine (Pinus montana] and, very locally, the Arolla Pine (P. Cembra) usually take the place of the Spruce Fir. But, of course, the Spruce and Larch are often found growing with the Beech, Birch, Sycamore, and other trees in the mixed woods of the lower mountain region. The Scots Pine (P. sylvestris) and the Silver Fir (Abies pectinata] are common in the lowlands and sub-Alps, but are rarely seen above 5000 feet. The Coniferous forests in Switzerland are under very strict regula- tions in regard to the felling of the timber. But in times gone by immense damage was done in many districts by the wasteful and indiscriminate cutting of the trees. Our artist has painted typical bits of Coniferous forest, skirting a flowery meadow at a height of some 4500 feet in a granite district above Argentiere in Haute Savoie. This is close to the Swiss frontier and at the eastern end of the Mont Blanc group. The great granite boulders strewn among the Firs and Larches afford an ideal home for the Rhododendron, and for such handsome herbaceous plants as the great mauve Mulgedium alpinum, the showy Rose-bay Willow-herb (Epilobium angustifolium) , and the rather scarce Umbellifer called Laserpitium Panax. The rocks themselves are sometimes partly hidden by dense mats of Saxifraga cuneifolia, which is like a miniature London Pride ; but it sends out long runners with rosettes of leaves at every few inches. The leaves are often purplish beneath. The Whortleberry and Cowberry (V actinium Vitis-idcea) form a thick undergrowth in many of these Alpine woods ; and Alnus viridis is abundant in the more open parts, and forms an important SUB-ALPINE PLANTS AND WHERE THEY GROW 9 feature in the landscape. Among other characteristic plants the following may be mentioned, viz. : Viola biflora, Saxifraga rotundi- folia, Poly gala chamabuxus, Linncza borealis, very local, Adenostyles glabra, A. albifrons, Gnaphalium sylvaticum, Homogyne alpina, Pyrola secunda, P. rotundifolia, and more rarely, P. uniflora, P. chlorantha and P. minor ; Phyteuma spicata, Melampyrum sylvaticum, M. pratense, Veronica urticcefolia and Maianthemum Convallaria. In the Beech woods, at a lower elevation, we find such plants as Dentaria, Paris, Listera, Cephalanthera rubra, Neottia Nidus avis, and various other orchids, of which several are semi-parasitic. CHAPTER II ALPINE FRUITS AND BERRIES MANY of those who visit the Alps in late summer or in autumn miss the great wealth of flowers which form such a feature in the landscape earlier in the season. Many visitors arrive too late to see even the lingering blossoms of Rhododendron, the Alpen Rose or Rose des Alpes, of which the Swiss are so justly proud ; while the small deep blue Gentians are in August found only on the higher mountains, and never in the splendid luxuriance of June. Their place is taken in autumn by the pretty Fringed Gentian (G. ciliata], a biennial species with long hairs on the margin of the corolla-lobes — which loves shaly limestone slopes, both in the Alps and foot-hills, and by Gentiana germanica with its purple-red flowers which continue in bloom in the sub-Alps until mid-October. The handsome ultramarine spikes of the Willow Gentian (Gentiana asclepiadea) may also be seen adorning mountain thickets and shady slopes until the end of September, brit the plant is rare in Western Switzerland and the Jura. The beautiful Marsh Gentian (Gentiana Pneumonanthe) , which brightens some of the damp, sandy heaths in Dorset, Hants, and Yorkshire is another autumn flower which is perhaps as beautiful as any when its large blue bells streaked with green open to the sunlight, and stand erect some- times singly on a stalk and sometimes in threes and fours on leafy stems a foot or eighteen inches high. The Marsh Gentian is more scattered in Switzerland than in England, but perhaps less abundant locally. In late summer and in autumn, long after the meadows and the lower pastures have been mown a second time, and when the characteristic forest flora has also mostly disappeared, the numerous red and ' black ' berries are continually attracting the eye of even the most casual of visitors to the mountains. Long before the end of such a hot and dry season as that of 1911, when many plants were withered up prematurely, berries and fruits of various kinds and many colours were particularly noticeable, and often they formed the chief means of table decoration in Swiss hotels, in addition to sounding the loudest note of colour in the woods and on the mountain-side. 10 ALPINE FRUITS AND BERRIES 11 But, exceptional as was the weather last summer, in any season towards the end of July, when the crowds are at their height, the Alpine berries begin to show themselves, and we realise that ' spring/ even in the Alpine sense, has gone. At best the Alpine summer is not a long one, and in the short space of about three months much has to be gone through — the face of Nature is continually and rapidly changing, and many plants have to develop, blossom, and ripen their seeds in quite a brief period of time. It was thought that a short chapter on some of the Alpine berries and fruits might be of interest to some of the vast multitudes of late visitors to Switzerland, who may be attracted by the abundance of the crop, but who are not, perhaps, in every case familiar with earlier stages of the plants ; or in other cases they may know the flowering stage well enough but fail to recognise the fruit which follows it. The Bilberry or Whortleberry (V actinium Myrtilus), which often grows finer in the Alps, and particularly in the Chamonix valley, than at home, was losing its flavour by mid-September last year, when its leaves were turning a brilliant crimson so that mountain sides seemed ablaze with them. But wild Raspberries were even at that late date in the best of condition at about 6000 feet, and as delicately flavoured as any in gardens. The Wild Strawberry also lingered on until plants in some of the higher regions must have been embedded in the first September snows. That year in the Mont Blanc district the first cold spell came about I5th September, but by ist October the weather was extremely cold and wet, and snow covered the mountains to within a thousand feet of Geneva. But to return to the Bilberry, whose fruit begins to ripen in sub-alpine regions usually about mid- July, it is interesting to note that not infrequently on the older rocks — it is rarely seen on limestone — this common plant ascends to 9000 feet in the Maritime Alps, as, for example, on Monte Santa Maria, and it may sometimes be found as high in Savoy and in the Southern Swiss Alps. The Bog Whortleberry (V actinium uliginosum) ascends even higher in Alpine turbaries in Switzerland, where it has been recorded from 3000 metres, or nearly 10,000 feet. Its leaves are bluish green or glaucous on the under side, and always entire (not slightly toothed), and its berries resemble those of the Common Bilberry, but are insipid to the taste, and often rather smaller. The Cowberry (V actinium Vitis idcea] is very beautiful in both flower and fruit. It is a low shrub, sometimes not six inches in height, with wax-like, flesh-coloured blossoms, evergreen leaves, often turning red in autumn, and brilliant scarlet berries which are very attractive. It grows abundantly in Alpine woods and on moors or on beds of mould about rocks from the plains up to 10,000 feet in Switzerland. The Cranberry, of still the same genus (V. oxy coccus), grows only in sphagnum bogs, as in Britain, but its 12 SUB-ALPINE PLANTS delicate drooping crimson flowers on long slender pedicels are fugitive and very difficult to find, being less conspicuous than the well-known yellowish red fruit. We have not seen the Cranberry at a higher elevation than 5000 feet, as, for example, in the marsh by the picturesque Lac Champex in Switzerland. The stems are very wiry, and the leaves quite small, rolled in at the margin, glossy green above and glaucous beneath. Closely allied to the Vacciniums are the Bearberries (Arctosta- phylos alpina and A . Uva ursi) , both of which are distinctly Alpine in character and habitat, though the latter species descends to the plains in Switzerland. The Alpine Bearberry has black berries, which ripen the second year, and thin, netted veined annual leaves, finely toothed at the margin. The Red Bearberry (Arctostaphylos Uva ursi) has red berries and thick, leathery, evergreen leaves of a flossy green on the upper side, with sunken dots on the under side, t is chiefly found on limestone. Both species are found in Scotland, and the latter appears also in the north of England and north-west Ireland. Sometimes great mats are formed by these prostrate shrubs. The flowers resemble those of the Arbutus more than those of any other plant. The Crowberry (Empetrum nigrum) is a low, wiry shrub, with heath-like leaves and small blue-black fruit, smaller than those of the Bilberry, which often ascends to a high altitude and sometimes covers enormous areas of moorland where little else will grow but lichen. It grows not only in the mountains of Europe, and in the British Isles, but penetrates the Arctic regions of Iceland, Green- land, Siberia and Labrador. It gives its name to the extremely small family of Empetracece, which comprises only four species in the whole world. Among other low bushes bearing berries in the mountains is the Stone Bramble (Rubus saxatilis), which is frequent in Scotland and the north of England, as well as in some of the hills in South Wales and the West of England. In the Alps it is found in open woods and bushy places, and it is scattered over the mountain regions of Europe, Central Asia, and Siberia. The Stone Bramble is a very dwarf and distinct species, whose rootstock sends out a few creeping runners rooting at the nodes and ascending stems often only six or eight inches high, with a few small prickles, though sometimes quite unarmed. There are usually three pale green leaflets, rather thin in texture and resembling those of the Dewberry ; and the petals are a dirty white or greenish colour and very narrow. The berries or drupes are a rich red, few in number, but large and tempting to the eye in their luscious transparency. However, they are disappointing when eaten, for they are strongly acid and each drupe consists chiefly of a large pip or seed. The Cloudberry (Rubus Chamcemorus), so well known in Norway, where its orange- red fruit is stewed and served at table under the name of Multebcer, ALPINE FRUITS AND BERRIES 13 does not appear to grow in the Alps, but its large, solitary, white blossoms, on stems only a few inches high, are often seen in turfy swamps and wet heaths in Northern Europe, Asia, and America. This species of Rubus is one of the few British plants not'found at all in Switzerland or France. The berries are first red, and they turn yellow on ripening. Of the ordinary kinds of Blackberry, or Rubus, many of which grow in the Swiss lowlands, very few appear to reach the mountain forests. Perhaps Rubus tomentosus is the most distinct of any which flourish in such places. It is a pretty Bramble, and easily known by the greyish tomentum or felt which covers its leaves and calyx, and by its small yellowish white flowers. It is abundant in the Eastern Pyrenees, and extends right across Central Europe and as far east as Persia. Probably in that very mountainous country it reaches a higher altitude than in Europe. Among Roses there are several in addition to the beautiful Rosa alpina found in Alpine or sub-alpine regions. The true Alpine Rose, or Eglantine, whose deep rose blossoms adorn the open woods and broken, rocky pastures up to nearly 8000 feet in June and July, usually has long, narrow hips of the richest red. The hips of Rosa pomifem, which is widely spread throughout the Swiss Alps, though very rare in the Jura, are very large and round and generally, though not always, covered with bristly glands. In early autumn their rich orange colour, deepening to a beautiful crimson, makes them an attractive feature in the landscape. The pretty little Burnet or Scotch Rose (Rosa pimpinellifolia) is very rare in Switzer- land, except on the borders of the Jura. Though this very prickly little rose grows close to the sandy seashore in parts of England and Wales, we once found its delicate cream-coloured blossoms at 7000 feet in the south of Savoy. To find even a few plants of this Rose on the stony southern slope of a mountain at that height intermingled with some truly Alpine species, was one of the sur- prises of an eventful season devoted to the exploration of the Western Alps and their supremely rich flora. The fruit of the Burnet Rose is nearly globular, and blackish red at maturity. The poisonous scarlet berries of the Mezereon (Daphne Mezereum) are often seen hi the woods of the plains and on stony pastures and slopes of debris up to about 7000 feet ; but, as in England, this bush is more often seen singly or in pairs than in groups. The pink, scented flowers appear in March, before the leaves, or a month later in the higher elevations. There are two or three Alpine species of Honeysuckle, or Lonicera, in Europe ; the Blue-fruited Honeysuckle (L. ccerulea) is a shrub three to six feet high and of stiff habit. The yellowish white flowers are scentless and in pairs, but their ovaries coalesce into one globular and bluish-black berry. It is spread over the Coniferous forest zone ; on moors it descends lower, and occasionally, as at Saas Fee, it ascends the rocky slopes to a height of 8000 feet. 14 SUB-ALPINE PLANTS Lonicera alpigena is a bush of about three feet which has much larger leaves and a shining berry resembling a small, double cherry. It frequents woods and rocky places in the mountains. The Black Honeysuckle (L. nigrd) is a sub-alpine shrub, a yard or two in height, with small flowers in pairs, which develop into a pair of black, rounded berries united at the base. In many of the shady ravines and wooded gorges one sees an elegant Alpine Elder -tree (Sambucus racemosa), which in late summer and autumn is usually heavily laden with dense clusters of small round berries of a blood-red colour. It grows well among the granite boulders and tall ferns bordering the road which skirts the Tete Noir and overlooks the famous Trient Gorge between Martigny and Argentiere. Indeed, most of the fruit-bearing shrubs and bushes mentioned in this chapter can be seen in a walk along that picturesque route. Here also can sometimes be found the fruits of two kinds of Polygonatum, or Solomon's Seal, as well as those of an allied plant called Streptopus amplexifolius, or Knot- foot. The globular, crimson fruits hang on delicate flower-stalks springing from the leaf-axils and always bent at right angles half- way down, so that this curious plant with very handsome ' berries ' is unmistakable when once seen. It is, however, by no means common. It sometimes grows by the side of huge granite boulders, as near the main road crossing the Col des Montets, and occasionally it can be seen under the shade of a Mountain Ash, whose scarlet berries ripen at the end of August in the higher regions. Autumn visitors to the Alps sometimes have their attention arrested by a spiny bush of stiff habit, with narrow, olive-green leaves and orange-yellow almost stemless berries, which are much more densely attached in axillary clusters to the main axis of the shrub than to its branches. This is the Sea Buckthorn (Hippophcz rhamnoides). In other countries it grows on the sea coast, and in England and the north of France it is planted on sand-hills to mat the sand together, but in parts of the Alps it grows naturally in the sandy beds of rivers, both by glacier streams and large rivers such as the Rhone. At the foot of the Col de Balme we have often seen bushes of it situated as high as 5500 feet. It is a somewhat curious example of a littoral plant which ascends to considerable heights in the mountains, though where it does so it is always either in river beds or on steep, sandy screes. But even in such places on the mountains it very probably answers the same useful purpose and prevents the steep slopes of sand and debris from being washed away by torrents of surface water. Wild Gooseberries (Ribes Gwssularia) are frequent in many parts of Switzerland, particularly by roadsides and stony, bushy places in sub-alpine valleys. The berries are usually small and yellowish when ripe, generally glabrous in the mountains, but often covered with stiff glandular hairs in the lowlands. ALPINE FRUITS AND BERRIES 15 One of the commonest and most picturesque of the bushes bearing berries is the Barberry (Berberis vulgaris). It is a glabrous shrub, six or eight feet in height, with yellow wood like others of its family. The branches are armed with three-lobed thorns at the base of the tufts of leaves. The yellow flowers, in elegant drooping racemes, appear in May or June. The berries are oblong and very acid, green at first, then golden and finally bright red. In a single walk such as that spoken of above, from Martigny over the Col de la Forclaz (nearly 5000 ft.) down the steep escarpment to Trient, round the Tete Noir and down to Chatelard on the French frontier the fruit of the Barberry can be seen early in August in every shade of green, yellow and red, according to the altitude. In the hot slopes above Martigny it will be already crimson, while nearer the Forclaz the young fruit is still in its tender green stage. Similar transformations can, of course, be seen in walking from the Rhone Valley up any of the beautiful valleys to the south leading into the heart of the Pennine Chain. CHAPTER III THE CULTIVATION OF ALPINE PLANTS THE culture of Alpine and rock plants as a hobby is increasing by leaps and bounds. We remarked a year ago that nothing was more indicative of this increasing fashion than the number of books issued in recent years on the subject, and the amount of space devoted to it in horticultural journals. Since then several more books have appeared, including a practical and prettily illustrated little volume on Rock Gardens and Alpine Plants by Mr. E. H. Jenkins, who has had much experience in the making of rockeries and the management of Alpine and other hardy plants. In Mr. Flemwell's last volume, The Flower-fields of Alpine Switzerland, the latter portion of that beautifully illustrated work was devoted to a plea for the formation of Alpine fields in England, and some very plausible arguments were advanced for the intro- duction of Swiss pasture and meadow plants into grassland as an adjunct to our rock-gardens. It was also proposed to decorate with Alpine flowers not only some of our parks and public places, but it was suggested that many a wayside field, copse, bank or railway-cutting might be improved ' by taking a leaf from Nature's Alpine book.' Theoretically such an idea is excellent, and it is true that many of the handsome sub-alpine plants of the Swiss meadows and open woods would figure largely in any such scheme ; and that some of these flowers of the lower mountains have been neglected by gardeners. Some horticulturists are ready to look kindly only upon anything that will grow on a rock, and to call it ' Alpine ' ; and certain small Alpine meadow and pasture plants frequently planted on dry rockeries in England languish and die because they are out of their natural habitat. For the suggestion that a small field or enclosure adjacent to a rock-garden should be converted, with skill and taste, into an Alpine pasture, we have nothing but praise ; and it has already been successfully done by several gentlemen. It is only fitting that a large rock-work should, where practicable, be completed or supplemented by an ' Alp ' or small field where numerous meadow and woodland plants could be established and grown to advantage. But, we say — let it stop there, and chiefly for this reason. If many 16 THE CULTIVATION OF ALPINE PLANTS 17 foreign plants were introduced into out fields, copses, and railway- cuttings, and especially any Alpine species which do not already grow wild in England, it would soon upset the balance of distribu- tion of our native flora, and the calculations of future generations of students in geographical botany. It must not be forgotten that the topographical distribution of the native plants even in these small islands is a subject abounding in interesting points, and the fact that it has been suggested of recent years that some of the commonest species such as the White Dead-Nettie (Lamium album), hitherto supposed to be indigenous, were introduced by the Romans or more recently, makes it all the more incumbent upon us not to ' make confusion worse confounded.' Therefore, however poor in floral wealth and colour some of our own fields and meadows may be in comparison with those of Alpine countries, let us be satisfied with our Primroses and Bluebells, our Buttercups and Daisies,and not sacrifice science to artistic effect, however tempting the experiment may be. In regard to the making of rock-gardens, we do not propose to offer more than a few very general remarks, for, in addition to the fact that there are practical books already devoted to the subject, this is emphatically a case in which a little practice is worth much theory. Much can be learnt by observing Nature, and by noticing the way in which many plants grow upon the rocks at home, and how they adapt themselves to different local conditions. A single visit to the Alps will teach still more. In making a rockery the chief thing to secure is thorough drainage of the subsoil, and this can usually be obtained by digging away a foot or two of the soil before any rocks are laid, and placing a layer of broken stones, etc. of various sizes before the soil is replaced. It must not be forgotten that in the Alps the plants grow, for the most part, in naturally drained places, where water does not stagnate. In the long Alpine winter they are kept dry and at a fairly even temperature by a deep coating of snow ; and when spring arrives, the melting of the snow around the plants gives them a good start, while as the growing season advances the deeply penetrating roots are given a copious supply of water from the ever-melting snow above, which moisture sinks into the porous ground or trickles down the mountain slopes. Therefore, in our gardens, the first thing to guard against is excessive moisture in winter — we can well imagine the numbers of ' Alpines ' which have been killed by the persistent rains of the present winter, 1911-12. The second precaution must be made in spring. In early spring there is a danger of some of the more delicate subjects being shrivelled up by cold east winds and brilliant sun, so that they should be watered carefully and only when there is no sign of frost. As early summer approaches most ' Alpines ' should be well watered once or twice a day. i8 SUB-ALPINE PLANTS Much can be done in order to protect some plants from the effects of our damp and comparatively sunless winter. Sometimes if a piece of glass or slab of stone be placed in a horizontal position above delicate plants they will be protected from excessive rainfall or drip. The soil around the base of the stems or rosettes of leaves should not be allowed to become clogged and foul, or coated with green liverwort, moss, or other weeds. This can be easily prevented by carefully disturbing the top soil, removing the moss, etc., and top-dressing with grit, sandy loam, bits of limestone, sandstone, or sometimes a dressing of leaf-mould. This top-dressing is of the greatest importance, and when done judiciously it cannot fail to be of benefit. It applies even more to young plants in pots or boxes in greenhouses and frames, for it is in such places that the growth of liverwort, etc., is often most rapid. We have found the simplest way to remove the green moss or Marchantia is with the flat, sharpened end of a thin piece of wood, such as an ordinary plant label. By holding the pot in one hand, and the flat wooden tool between the finger and thumb of the other, so that it does not deeply penetrate the soil, the coating of green slime or moss can very quickly be removed. A few small pieces of grit or a little dry sandy loam should then take its place. Another thing to guard against is the ' coddling ' of Alpines in warm or ill-ventilated greenhouses. They cannot have too much air, and most of them do far better in the open than under any glass. This somewhat artificial method of cultivating hardy plants may be necessary sometimes, but it frequently tends to produce a less robust race, with many individual specimens drawn out in quite an unnatural manner. It is well known that one of the most characteristic features of nearly all the higher Alpine species is their dwarf habit, with stems frequently only a few inches in height, often with a rosette of leaves at the base, and very long fibrous roots which sometimes penetrate several feet into the soil. By this means they are prevented from being blown away by the furious blasts of wind so frequent in high mountains, and at the same time the long thick fibres absorb moisture and nourishment from the soil through which they pass. Most Alpine plants can be grown from seed, and many are better obtained from this source than from established plants, because much of the material sent to England by collectors arrives with insufficient root. It is very difficult to get up the complete fibrous tap root of such things as Anemone alpina, Campanula barbata, Gentiana asclepiadea, etc. Again, many plants die in transit to a distant country. Moreover, when seed is collected, rather than roots, there is less chance of disfiguring the mountain side. Seed should be sown as soon as possible after its collection. In saying this we merely follow Nature ; and it has been proved that many seeds refuse to germinate after a certain limited time. THE CULTIVATION OF ALPINE PLANTS 19 Although many Alpines may be sown in a suitably prepared bed in a sheltered position out of doors, some of the rarest and best kinds should be sown in pots or boxes in the following manner. The pots should be well drained and filled either with a mixture of sifted loam and sand, or with sifted sandy heath soil. The best preventative against weeds is either to bake the soil or soak it in the prepared pots with absolutely boiling water, which will destroy the seeds and spores of weeds and kill all insects at the same time. After the boiling water is used the pots must be left for a day or two before sowing the seed. The seeds should be sown on a firm level surface and have a very light and shallow covering, and some of the very small ones might be lightly covered only with triturated moss. The pots or boxes should then be gently watered with an extremely fine rose, placed in a frame or cool greenhouse, well shaded and kept at a uniform moisture. As soon as the seedlings appear they should be gradually hardened and exposed to the air, but not allowed to grow too lengthy, or nothing can be done with them. It is astonishing how rapidly some seedlings become too tall to be manageable in this delicate stage if proper care be not exercised. A few hours' sun might draw them up to such an extent that they cannot be watered without being beaten down like a field of mowing grass is after a heavy storm, which would make the subsequent operation of pricking out into larger pots or boxes one of great difficulty. This pricking out is a tedious business. The young seedlings are put in rows an inch or two apart, according to their size, kept again at a fairly uniform moisture, and more or less shaded from the hot sun, until large enough to be planted in the open. More usually, however, they are planted singly or a few together in pots, and placed in a frame and kept rather moist. In the winter they may be more freely exposed to the air and kept dry and clean. When the weather permits in spring, they can be transplanted into the open and treated like the old plants. It is important that every Alpine plant should be planted firmly, and the soil or stones should be pressed well round the plant. Alpine plants are also propagated by cuttings, by division of the rootstock or by layers. This is best done in spring, before growth begins, or in the autumn after it is completed. Most rock, Alpine, and sub-alpine plants and nearly all the Saxifrages, Semper- vivums, Primulas, and Androsaces can be easily increased by division. Saxifrages are among the easiest of all Alpine plants to grow, and many will thrive under ordinary conditions in an English garden. Special care should be taken that all, except a few water- loving species, such as Saxifraga Hirculus, S. aizoides, and 5. stellaris should be in rather dry, sunny places and not under trees where water drips. However, such species as 5. rotundifolia and S. cuneifolia like to be in the shade of trees and especially among 20 SUB-ALPINE PLANTS big boulders. S. cuneifolia is particularly useful for quickly covering up rocks and ugly banks with its great tangled mass of pretty foliage. Most of the ' encrusted ' section will benefit by top-dressing with gritty loam in early autumn. Some should be wedged tightly between stones ; and in dealing with small kinds, such as ccesia, diapensoides, Burseriana, etc., care should be taken that they do not get washed out of their place in winter. The small rosettes of encrusted Saxifrages may be transplanted at any time, and it strengthens the flowering shoot if the offshoots are removed. They may be planted in ordinary pots filled with sandy loam. S. longifolia may be placed between a couple of more or less upright rocks, so that water cannot collect in the large rosettes. It takes two or three years to come to maturity, and after flowering and seeding it dies. 5. florulenta is another handsome species to be treated in the same way, but it prefers a vertical position, and has a still greater hatred of surface moisture. It should, however, have plenty of moisture in the soil. Grit is beneficial to most of the Saxifrages because it checks the evaporation of moisture in summer, and prevents damp from stagnating round the collar of plants in winter. The reason why roots are often found in a network over the surface of a stone is because stones in the soil remain cool and moist, even in summer. It is therefore well to mix a quantity of stone chips with ordinary loam when making a rockery. They tend to keep the soil open and porous rather than sodden and water-logged. The air can penetrate further, and frost exercises its pulverising influence on a broken, gritty soil better than on a dense, compact one. Saxifrages of the oppositifolia group die away in two or three years and should be taken up and pulled to pieces in fresh soil, and grit and leaf-mould may be worked into the shoots as a top- dressing. Though in the wild state many Saxifrages grow almost solely on limestone, and a few seem to thrive only on granitic rocks, it has been found in cultivation that they are not so particular, and the great majority will live in an ordinary loamy soil, especially if it contains a fair proportion of lime. In my former volume x I did not sufficiently emphasise the fact that in the Alps themselves certain plants avoid calcareous soil in some districts, while they tolerate it in others ; and in a few cases I was tempted to generalise about them in a manner which further observations and reading have proved unwise. For example, one of my kindest critics points out that the common Ling (Calluna vulgaris) is not strictly speaking a lime hater, for it is fairly common on the hillsides of the Dolomites, where it grows mixed with Erica carnea, which almost always affects limestone soils. Then 1 Alpine Plants of Europe, p. 5. THE CULTIVATION OF ALPINE PLANTS 21 again Rhododendron ferrugineum does not invariably grow on pri- mary rocks. I saw it last year on the limestone in Switzerland ; though possibly it was an apparent congener and growing there with the other species (R. hirsutum] because a sufficient thickness of peat separated it from the subsoil. Mr. Reginald Farrer has also pointed out in his last volume (Among the Hills) that "no reliance can be placed on rigid assignments of a plant to one stratum or another," and that this applies even to Anemone alpina and A. sulphur ea. But generally speaking the chemical and physical nature of soil is a factor of far greater importance in the distribu- tion of plants in relatively small areas than the physical configura- tion of the land. Many of the Primulas, such as P. Auricula, P. viscosa Vill., and P. latifolia, which grow on rocks in the Alps, may be planted in deep crevices between rocks ; but there must be plenty of good compost made of a mixture of peat, sand, and loam, or leaf-mould instead of the peat. The roots should be tightly wedged between two stones. Mr. W. A. Clark recommends the use of clay instead of loam to wedge the plants in, because it will hold moisture longer. The roots of Primulas should be well watered in spring and early summer. Some species such as P. glutinosa and P. involucrata do better in a northerly aspect, sheltered from the sun. P. integri- folia will cover damp, flat rocks if the soil is moist and yet well drained. It wants an abundance of water in spring, for it usually thrives best in the Alps just below the melting snow. The tiny P. minima hates lime, and likes sandy peat in a bare, open spot, though neither it nor the rare P. Allioni should be allowed to become very dry. P. Allioni is endemic in the Maritime Alps, and grows most luxuriantly in limestone grottos or small caves. Mr. W. A. Clark suggested the placing of a large stone to hang over this Primula, about a foot above the plant, sloping in towards the bank, so that rain may run off to the roots in a sort of little pit lined with clay and filled with loam and broken limestone. To propagate Alpine plants by cuttings, a method particularly applicable to shrubs and certain hard- wooded plants, such as Helianthemum, Cistus, Daphne, Rhamnus, etc., half-ripe branches should be cut off in autumn and placed in a shallow pan or bed. The cuttings should not be more than three or four inches long ; the lower leaves should be trimmed off, and the shoots must be cut immediately below a joint, whence the roots will spring. There should be good drainage, and the compost of loam and sharp sand can be made more porous by adding pieces of charcoal. Each cutting should be firmly placed in little holes about an inch and a half deep, which are drilled with a stick or ordinary lead pencil, and a little silver sand can be dropped into each hole. After the earth has been firmly rammed down, the cuttings may be placed in a cool frame, or in some shady place covered with a bell-glass, 22 SUB-ALPINE PLANTS and allowed fresh air daily. They should be kept uniformly moist, but not too moist. When the young shoots have grown some size and become rooted they should be gradually accustomed to the open air until ready to be transplanted. Many of the Helian- themums, or Rock-roses, can be grown from cuttings in a properly prepared bed in a sheltered position in the open. Lastly, those Alpine plants which have runners, such as Linncza borealis, can be increased by merely detaching separate pieces and replanting them firmly in shaded beds or in pots. Some of the dwarf Campanulas with a creeping rootstock can be similarly treated. Some hard-wooded shrubs, such as Azalea, certain Daphnes, and Rhododendrons, which don't ripen their seeds in this country, and are difficult to strike from cuttings, can be increased by layering. A suitable branch near the ground is chosen, cut half through near a joint, and then pegged down firmly and covered with a compost of loam and sand an inch or two deep. If by the following spring roots have been formed, the layered portion can then be cut from the old stock. The greater number of sub-alpine plants which grow in the woods and meadows, and many of the true Alpines, may, if desired, be treated like ordinary garden plants. Even forty years ago this was realised by Messrs. James Backhouse and Son, who said in issuing their Catalogue for 1871 : ' A large proportion of the truly Alpine species, which find their natural home in the crevices of rocks at a great elevation, grow with perfect ease in an open border in ordinary loamy soil. And, strange to say, some that succeed with difficulty on artificial rockwork, flourish well under such circumstances, and thus bring within the range of every garden a large and varied amount of beauty.' Many could be planted in turf, and perhaps some of the woodland denizens might be tried under trees, where little else will grow, provided the foliage is not very dense. Some of the Orchids, Butterworts, Parnassia, Primula farinosa, and many others frequenting damp places, should have a peat or bog garden prepared for them at the foot of the rockery. CHAPTER IV SOME ALPINE GARDENS 1 BOTANIC gardens are increasing in numbers in the Alps, just as rock gardens are becoming more and more numerous in the British Isles. The most recent of the Swiss Alpine gardens is that at Rigi Scheidegg, at about 5400 feet, which was opened by Professor Carl Schroeter, of Zurich, in July, 1909, and of which Dr. Bachman, of the Lucerne Gymnasium, is the Director. The German-Swiss have taken the lead from Monsieur H. Correvon and his Geneva friends in starting these interesting and useful mountain gardens. Monsieur Correvon was the President of the Association for the Protection of Plants, founded in Geneva in 1883 to struggle against the destruction of the Alpine flora ; but in 1908 the Association was amalgamated with the Swiss League for the Protection of Natural Beauty, which corresponds in many respects to our Selborne Society. It is wall-culture that the Swiss understand perhaps better than most people ; and Monsieur Correvon, at Chene Bourg, near Geneva, has a low wall which is a perfect paradise of interesting and rare saxatile flowers in early summer. We have also seen the famous wall at Valleyres, at the foot of the Jura, in Canton Vaud, which Boissier made in 1856, and where he cultivated some of the best Saxifrages and rock Primulas, including a very fine patch of Saxifraga Kotschyi from Asia Minor. They are still thriving, for his son-in-law, Monsieur William Barbey, has taken the same interest in the plants, and does all he can to cherish and extend the work started by his illustrious relative. The town of Geneva has planted many wall-plants on what remains of the old fortifications, and these are doing well. Some of the mountain railway companies have also decorated the walls bordering their railways with rock-plants, which tend greatly to brighten the scene in spring and early summer. The oldest of the gardens in the Swiss Alps is the LINNJEA, on a hillock which dominates the quaint village of Bourg St. Pierre, the last village on the road to the great St. Bernard Hospice. It was founded in 1889, with Professor Chodat of Geneva as President 1 Some of these notes are based upon articles by the author already published (sometimes anonymously) in the Gardeners' Chronicle. 23 24 SUB-ALPINE PLANTS of the International Committee, and with Monsieur Correvon as Director. Lord Avebury, the President of the Selborne Society, the late Professor Romanes, Miss Willmott> and other well-known English scientists have always taken a keen interest in the garden, and it was with their help that the ground was bought in 1888. The garden now comprises about three thousand kinds of plants, of which the majority seem well established. It is on granite, and over two hundred of the granite-loving plants growing naturally in the district have been left to their own devices on the rocky prominence which overlooks the picturesque but dirty village of St. Pierre at a height of about 5500 feet. Bourg St. Pierre is about fifteen miles on the great St. Bernard route from Martigny in the Rhone Valley to the beautiful city of Aosta in Piedmont, a total distance of forty-five miles. Visitors to the famous Hospice (8100 ft.) who are interested in flowers should spend an hour at the Linnaea garden en route; and if they have the time they will do well to stay the night at the little Hotel du Combin just beyond the garden, which modest hostelry will be found clean though primitive. The village of St. Pierre contains relics of more important days, like Lanslebourg, at the foot of the Mont Cenis, with which the nistory of the famous Pass is bound up. The church is very ancient, and in the churchyard wall is a Roman milestone of the younger Constantine. As early as the ninth century the original Hospice was here. In May, 1800, Napoleon's visit to the village with 30,000 men on his way across the Great St. Ber- nard is commemorated by the name of the older inn, " Au Dejeuner de Napoleon," the room which he occupied being worthy of a visit. The flora is interesting all the way from Martigny to the top of the grand St. Bernard Pass, and in the lower part of Val d'Entre- mont, above Sembrancher, where the picturesque Val de Bagnes joins the main valley on the east, the botanist will find various plants usually characteristic of a warmer climate together with Alpine species which have descended from the neighbouring moun- tains. Thus the yellow Ononis Natrioc and bright pink 0. rotundi- folia, the very handsome purple Vicia onobrychioides (common in the Pyrenees) , Caucalis grandiflora, the deep yellow Euphrasia lutea and Campanula bononiensis (of chestnut groves in the Maritime Alps) may be found side by side with Scutellaria alpina, Sempervivum montanum and S. arachnoideum, Poa alpina, Juniperus Sabina, etc. At Sembrancher the celebrated botanist, L. J. Murith,1 was born in 1742. He was a Canon of the St. Bernard Hospice, and a corre- spondent of de Saussure. He was the first to ascend Mont Velan, that ice-clad peak which forms such a beautiful object from the Jardin de la Linnaea or from the lovely Valsorey just beyond. Murith's name is commemorated in Saxifraga Murithiana, a form 1 In 1810 Murith published a Guide du Botanist* qui voyage dans le Valais. SOME ALPINE GARDENS 25 of 5. oppositifolia which grows in the Western Alps and Pyrenees. The Botanical Society of the Valais also bears his name. On entering the Linnaea garden from the road on the north side, several shady, winding paths lead up the steep hillside which is clothed with the tall mauve spikes of Mulgedium alpinum, the rosy heads of Adenostyles> with leaves like Coltsfoot, the nodding blossoms of Cortusa Mathioli, and those of the lemon-yellow Primula Sikkimensis. The red-brown Gentian (G. purpurea), and its speckled yellow relative, G. punctata, grow naturally on this slope, and so do the handsome purple madder Lilium Martagon, the steel-blue Eryngium alpinum and the great white Achillea macrophylla with deeply cut leaves. Then on the bit of natural cliff above are such plants as Saxifraga Cotyledon, whose great panicles of white blossom, eighteen inches in length, festoon the black, weather-worn cliffs on the Italian side of the Simplon, just above the village of Iselle. Before reaching the summit of the garden we pass rockeries de- voted to Saxifrages, Sempervivums, Pinks, and Primulas, and others which are devoted to the plants of special countries or mountainous regions. Besides the European Alps and the Jura, the Pyrenees, Caucasus, Himalaya, Atlas, North America, and the Arctic regions are all represented by separate rockeries. In the Balkan rockery, built by King Ferdinand of Bulgaria, is a fine selection of Balkan plants sent by his Majesty from Sofia. Self-sown poppies (P. nudicaule) of Siberia and other Arctic regions, in yellow, white, and orange, give a blaze of colour to the scene, and the smaller, more delicate Alpine Poppy thrives there equally well, and sometimes hybridises with the other. On our first visit to this garden at the end of June, 1908, among the Arctic plants noticed were Epilobium latifolium from Labrador, with blossoms two inches across, Chrysosplenium glaciale, from Lapland, and Polemonium campanulatum in abundance. We saw the beautiful pink Androsace Chumbyi and Primula Cashmeriana from the Himalaya, and Lindelfia speclabilis with its drooping flowers in purplish blue. The collections of Primula and Saxifraga are particularly good. Saxifraga cochlearis, endemic in the Ligurian and Maritime Alps, grows well at this altitude, notwithstanding the colder climate, and S. Aizoon rosea, with red stem and calyx, forms a striking variety of this common but very beautiful and variable species. The Pyrenees are well represented by such species as Saxifraga capilata, S. longifolia, Erinus hirsutus, Reseda glauca, Geum pyrenaicum, Eryngium Bourgatii, and the tiny Dianthus brachyan- thus, only two inches in height. Saxifraga Camposii, with its large, pure white flowers, was represented from the Spanish Sierras. Among the orange-red Composites, so conspicuous by their brilliant colouring, were Senecio tiroliensis, S. aurantiacus, and the 26 SUB-ALPINE PLANTS bright red Hieracium aurantiacum. These plants afford good examples of the deepening in colour at high altitudes of plants of two genera, the species of which are almost always characterised by yellow flowers in the plains. Primula is another genus in which a pale yellow colour predominates in the lowlands, but which is represented chiefly by red or purple flowers in the high mountains. Again, in the great Saxifrage genus there are several in the high Alps with red flowers, such as 5. oppositifolia, S. biflora, and S. retusa, though we do not know a single red-flowered Saxifrage indigenous in the plains of Central Europe. The THOMASIA garden at Pont de Nant above Bex, in Canton de Vaud, is smaller though quite as beautiful, and it is one of those which are laid out on strictly scientific lines. This garden is called Thomasia, after an early botanist at Bex, who belonged to a family who made collections of dried plants and minerals for sale. Some of the Thomas family were among the earliest visitors to Zermatt in the middle of the eighteenth century in search of rare plants. The garden is on limestone formation, and is situated at the foot of the precipitous sides of the Grand Muveran, at about 3800 feet above the sea. Started originally by a society in Bex, it was after- wards taken over by the Canton de Vaud and affiliated to the University of Lausanne, and it is under the management of Professor Wilczeck. The RAMBERTIA is also a limestone garden. It is romantically situated at the summit of the Rochers de Naye, above Montreux, and is one of the very highest gardens in Europe, being at an eleva- tion of 6900 feet. For the most part it is laid out on the southern face of a more or less precipitous cliff, from which in fine weather a magnificent panorama of mountains can be enjoyed. Here again Monsieur Correvon has made the most of striking surroundings, and the result is an attractive display of Alpine flowers growing in unique circumstances, while everywhere the Iceland Poppy seems to have found a home for itself. Let us now pass to Geneva, the Mecca of botanical science, and say a few words about its new Botanic garden, for of all the gardens we have ever visited the Geneva Alpine garden is arranged in the most thorough geographical order. Landscape gardening, as practised in England, seems hardly to be understood on the Conti- nent, especially in France and Germany ; so that for neatness combined with artistic effect we have seen nothing abroad to equal some of the English rock-gardens. Too often the stones are dumped down anyhow, as they still are in many suburban gardens in London and elsewhere. But at Geneva it is different ; and great skill has been shown not only in the conception of the garden, but in the arrangement and disposition of the rocks, and it is obvious that geological knowledge was shown in the execution of the whole thing. In all probability the distinguished botanist, Dr. John SOME ALPINE GARDENS 27 Briquet, who acts as Director of the Conservatoire Botanique and the Gardens, was himself largely responsible for their design. The Botanical Gardens occupy 75,000 square metres, or about sixteen acres of land overlooking the beautiful Lake Leman, with Mt. Blanc fifty miles beyond ; and they are separated by the railway from the Ariana Park. They comprise a systematic garden with the plants arranged according to Engler and Prantl, a young arboretum, greenhouses, etc., and the fine Alpine garden under discussion. The culminating rocks are those of the Swiss Alps, three groups comprising the flora of calcareous regions, and two granite masses represent the crystalline rocks. In early spring large clumps of Erica camea give colour to these rocks. Close at hand are several rockeries for plants of the Western Alps (Savoy, Dauphiny, and Piedmont) ; then comes one for those of the Maritime Alps, and a large mass for the Pyrenees, with various endemic species. Near them come the Spanish Peninsula and the Atlas Mountains. To the north-east are the following groups, viz. the Eastern Alps, Car- pathians and Balkans, the Caucasus, the Orient, the Himalaya, Altai and Siberia, Thibet and China and Japan. Among less important groups are the Central Plateau of France, the Vosges, Cevennes, Jura, with a splendid collection of its interesting plants, the Apennines and Sicily, Corsica and Sardinia. Towards the lower end are the isolated masses of the New Zealand Alps, with their shrubby Veronicas, etc., the Andes, and lastly North America with a very rich collection. From a grotto in the highest rocks of the Swiss Alps a stream of water emerges, and descending in a sinuous course across the Alpine garden, forms a small lake where various aquatic plants are grown. Probably the first botanic garden at Geneva was the one laid out many years ago on the natural system of classification by Pyrame de Candolle, who was Professor of Botany at Montpellier University in the south of France and Director of the ancient botanic garden there. It was he who began the famous Prodromus, which was con- tinued by his son Alphonse, the great authority on geographical botany, and finally finished by his grandson, Monsieur Casimir de Candolle, the present head of the family. Geneva has given birth to many distinguished men, and the town and district have been the chosen abode of many others ; but her botanists alone were enough to make the place celebrated. In addition to the de Candolles, Edmond Boissier, the author of the Flora Orientalis, lived and died in the vicinity ; and of the distinguished living botanists it would ill become me to speak, except to say that they are carrying on the work which has helped to make their beautiful city famous. There are at Geneva no less than four important Botanical Institutions, including the private establishment of Messrs, de Candolle, with its fine herbarium and unique library, and 1'Herbier Boissier at Chambesy, with its library 28 SUB-ALPINE PLANTS and unrivalled collection of plants from the Orient. Then there is the Botanical department of the University under the control of the distinguished and energetic rector (Professor Chodat), and the Conservatoire Botanique, opposite the Botanic garden, which now contains as fine and complete an herbarium of European plants as any to be seen in Paris, Berlin, Vienna, or London. In a word, thanks to the kindness of individuals and to the public spirit of the town, it would be difficult for students desirous of studying European plants, both living and dead, and of in- vestigating their geographical distribution, to find a more suitable or congenial place than Geneva in which to prosecute their labours. There is also at Geneva an excellent school of horticulture. Having spoken thus of Geneva, it is only natural to make a brief allusion to another important Swiss centre of botanical research, viz. Zurich. Indeed, for young students the facilities offered there are remarkable, for in addition to the University and a small but useful botanic garden, under the able directorship of Dr. Schinz, the Professor of Botany, there is the famous State Polytechnicum, perhaps the best of its kind in Europe. Its botany school is under Professor Carl Schroeter, who is so well known for his extensive work on the Alpine flora. Alpine vegetation in all its branches is very thoroughly studied at Zurich, and that place is the head- quarters in Switzerland of the modern science of Vegetable Ecology or the study of Plant Associations. Those who wish to hear more on the subject should read the very useful pamphlet by T. W. Wood- head,1 reprinted from The Naturalist, May and June, 1908. Travellers in the Dauphiny Mountains will find a small but interesting Alpine garden, containing good specimens of rare plants, at the Col du Lautaret (6800 feet) and adjacent to the hotel. It is in the keeping of the Faculty of Science of Grenoble University. The surrounding scenery is very grand, and the district renowned for the variety of its flora.2 Acting on the assumption that monopolies are, generally speaking, not good, and from actual experience of both places, we have no hesitation in suggesting that La Grave, with its two comfortable hotels, will be found in some respects a more convenient and satisfactory place at which to make a stay in that delightful district. 1 T. W. Woodhead, Plant Geography and Ecology in Switzerland. 2 So long ago as 1843, when J. D. Forbes wrote his Travels through the Alps, he alluded to the Col du Lautaret and the neighbouring mountains being "clothed to a great height with pasturages of the utmost luxuriance, filled with a greater and more gorgeous variety of flowers than I recollect to have seen in any other part of the Alps." CHAPTER V ON COLLECTING AND PRESERVING PLANTS SOME hints on how to collect plants and dry and mount them for an herbarium may be useful to some readers, particularly as the subject is discussed either very briefly or not at all in most botanical books. Plants can be collected and preserved in Switzerland, or any other extra-tropical country, much in the same way as in the British Isles. Specimens are usually put into a japanned or painted tin, commonly called a vasculum ; while an ordinary large sponge-bag would in the Alps be found a useful adjunct or alternative, for it can easily be carried in the ruck-sack when on mountain expeditions, and is more convenient than a tin. Sponge-bags are light and fairly waterproof, and for many small fleshy plants, such as Saxifrages and Sempervivums, they are both convenient and handy. Some botanists, however, prefer to take into the field a light portfolio, furnished with leather straps and sheets of drying-paper, so that the plants, and particularly the more delicate ones, and those, like Veronicas, whose blossoms drop easily, can be put straight into paper, and sorted and rearranged in a proper press on returning to the house. We do not, however, much recommend the use of such a portable press, especially as it wastes time and is quite useless in wet or windy weather. Many of the tins carried by young botanists are bought ready- made, and are too short. For ordinary purposes the tin should be about fifteen inches long, seven or eight inches wide, and about two and a half or three inches deep. It should have rounded edges, and the opening, which is on the broad side, should be large enough to admit average specimens without difficulty or needless doubling. The cover to the opening is attached by a couple of hinges, and it fastens at the side by a sliding wire bolt. If this should work loose and there be danger of the lid falling open when carried, the bolt can be bent the least bit out of the straight and it will then hold firmly. The plant-tin is most conveniently carried from the shoulders by a leather strap ; but sometimes it has a thick wire handle at the top, which is convenient on occasion. On hot days the vasculum should be kept as much as possible out of the sun, for the metal gets very hot if exposed to brilliant sunshine. To 29 30 SUB-ALPINE PLANTS combat this difficulty, or rather to prevent its consequences, the writer often lays the first delicate specimens in a bed of fresh green leaves placed in the tin. If necessary these can be removed as the tin gets too full. When a sponge-bag is not carried, it is often an advantage to have a smaller tin, such as is sometimes called a sandwich-tin, which will go within the coat-pocket. Small and delicate specimens can thus be carried, or it can be used for wet or dirty roots which might damage delicate flowers in the larger box. A perfect specimen should have root, stem, leaves, flowers, and fruit — both young and mature if possible. If, as is often the case, the fruit cannot be obtained on the same plant with the flowers, it should be gathered separately from another. It is most important to get the fruit, and in a more or less developed state, for in some families, such as Crucifera, Leguminosce, and Umbelliferce, it is at times impossible without it to determine a plant correctly. Good typical specimens should be selected, not necessarily the largest, but the most perfect and convenient in size. When possible a root- leaf or two should be collected as well as stem-leaves, but, of course, in many small plants most of the leaves will be root-leaves. The sheets of paper upon which the specimens are finally mounted should not be less than about 15 x 10 inches, which is the size most cartridge paper cuts into, but i6Jxio is still better, and this is about the size adopted in the Kew Herbarium, and quite large enough for ordinary purposes, though exceeded in several of the other great public herbaria. When plants are not more than about fifteen inches tall it is better to put them into the tin and the press whole — not cut or doubled. When, however, a tall plant or shrub is dealt with, a good flowering branch should be cut off with several of the lower stem leaves, and the root leaves, if any, should be added separately, so as to give the complete habit as much as possible. A notebook should always be taken into the field, in which the names, when known, of all the rarer and more interesting plants should be entered, together with date, habitat, locality, and any- thing of special interest worth recording. These notebooks form the basis of both the temporary and permanent labels referred to later. When in a foreign country it is sometimes desirable for botanists to enter the names of all the interesting species they come across in their walks, whether they keep dry specimens or not, for such notes are sometimes useful long afterwards, and it is astonishing how quickly such things are forgotten if not noted down. A press is very simply made from two stout boards, about i6| x loj inches, and of sufficient thickness not to warp. The boards are best clamped together by cross-pieces at the ends, in the manner that drawing-boards are made ; and they are either furnished with strong leather straps — screws are not advisable — ON COLLECTING AND PRESERVING PLANTS 31 or the pressure can be obtained by placing glazed bricks, boxes of pebbles, or heavy iron weights on top. Such automatic pressure is best, for it adjusts itself to the diminishing thickness of the contents of the press as the specimens dry. A press of this kind, or a pair of them, can be taken to the Continent without much trouble ; but if a few plants only are to be collected, it would suffice to take a couple of pieces of thick millboard with either leather straps or thinner straps made of a kind of braid, or of the cloth that saddlers use, with buckles attached. Elastic bands are not recommended, for they break easily and cannot be adjusted like straps. To separate half-dried specimens from fresh ones, and to keep the whole mass fairly level, and generally to hasten the process of drying, we have found a few thin wooden ' ventilators ' or frames the size of the press, made of cross-pieces of wood half an inch wide and one-eighth inch thick, very useful. Sometimes strong wire work frames or lattices can be bought, which answer the same purpose, or they could be used instead of the wooden boards to form an actual drying-press Common blotting-paper should never be used for drying plants in ; it is too tender, it does not last, costs too much, and the plants often stick to it. Any coarse, stout, and unsized paper will do, and even old newspapers may be used as a last resort. It is not necessary to buy the specially made grey, absorbent paper, though as it lasts a lifetime it is not expensive in the end. Such drying-paper is supplied in four sizes by Messrs. West, Newman, and Co., of 54, Hatton Garden, London, at is. id. per quire or 155. a ream for the smallest size, which measures 16x10 inches when folded Suitable paper cannot always be bought in Swiss resorts, and if the stock has run short it is better to ask the stationer for some of his ordinary rough wrapping-paper. In Italy and France the tough, yellow or grey paper frequently used in grocers' shops will form quite a good drying-paper. Before the specimens are placed in the press they should be examined, and any superfluous branches, leaves, or buds removed, if a fairly flat object cannot be otherwise attained. Roots should have soil or sand shaken from them, and they should be washed if necessary, and dried in a duster. The plant is then laid out as naturally as possible on a sheet of drying-paper, and others are placed by it until the sheet is fairly covered. Several sheets of paper should be placed between this lot and the next, according to the nature of the plants and the thickness of the paper ; but the great idea in pressing plants is to dry them quickly, and thus preserve the colour as naturally as possible. The more paper used and the oftener it is changed and dried the better. At first the papers should be dried every day, in the sun or by the fire ; afterwards less often. If the paper is hot, all the better, and a hot iron is often a useful adjunct. The pressure should be light at first, and increased after 32 SUB-ALPINE PLANTS the first day, but the flowers and delicate leaves of some plants will shrivel if the pressure is not even and adequate. However, many a youthful collector is apt to forget that drying is the chief thing, and that the pressure can be easily overdone. At the first changing of papers the specimens can be rearranged while pliable, and super- abundant parts removed with scissors. Any stems with broken or ragged ends should also be cut clean. When quite fresh many specimens do not so easily yield to necessary treatment as now. Generally it is better to leave plants in the tin, rather than put them in water, if it is inconvenient to press them within one or two days, while many small kinds would remain fresh a week in the tin if in a cool place, though both leaves and flowers might lose some colour during that time. Most of the very thick or fleshy portions of plants, such as the head of a thistle, the bulb of a Daffodil, or the stem of an Orobanche, should be cut in two before being dried. In fact, the whole of a thick Orobanche or of a plant like Campanula thyrsoidea had better be split in two from top to bottom. Usually both halves are worth preserving. Woody stems also are better split in two, or at any rate thinned. In order to aid the drying of any such thick or fleshy plants or portions of plants, it is well to make pads of cotton-wool and place them both above and below the specimens. Cotton-wool can be bought in long sheets and easily cut with scissors the size of the drying-paper. It is better that the plants should not touch the cotton-wool itself ; but useful and more or less permanent pads can very quickly be made by loosely stitching together with a needle and thread a pair of folded sheets of drying-paper with the wool inside. Many succulent plants such as Orchids, Lilies, Sedums, and Semper vivums can be dried with the help of these pads, but it is best first to dip them in boiling water up to the base of the flowers. This kills the plant at once, and enables it to be dried more quickly, and with much less loss of colour. Thick Orchids should always be killed in this way, and their tubers and stems might first be pricked with the point of a knife to hasten the process of scalding, for the final result, particularly in regard to the green colour of the leaves, makes it well worth the trouble. Dipping in boiling water is also recommended in the case of Heaths, which shed their leaves while being dried. With the help of the notebook or diary already referred to, it is well to write on a rough, temporary label the name of the plant, if known, the place where it came from, date, and approximate altitude. It is interesting sometimes to add the kind of soil or geological formation. These labels should be placed with the specimens they refer to, and afterwards copied when the plants are mounted. If a series of one species or variety, especially when belonging to a critical genus, be collected, every example should ON COLLECTING AND PRESERVING PLANTS 33 have a little label or ticket with the same number, while one label only need have the full particulars. When the specimens are quite dry and stiff they can be packed close together, with only a single sheet of paper between each layer, and this paper need not be absorbent, but if it is unglazed the specimens will keep in position better when travelling, and not slip about so readily if the parcel is not quite tight. In hot countries it is desirable to poison collections of dried plants by painting them over with a solution of mercuric chloride or corrosive sublimate, to protect them against insects. This is done at Kew Herbarium, and also by a few amateur Botanists in this country ; but in England it is not really necessary, if camphor or napthaline be freely used, as is the case in the National Herbarium at South Kensington. In addition to spoiling some specimens, and to the subsequent peculiar blackening of the mounting paper in many cases, and to the offensive fumes which in hot weather sometimes rise from specimens treated with corrosive sublimate, the solution is, of course, a most deadly poison, and must be handled with great care. The preservative solution used at Kew is as follows : J oz. corrosive sublimate, | oz. carbolic acid, i pint methylated spirit. It is better that the specimens should be quite dry before they are poisoned. It is usually done with a large camel-hair brush, but there should be no metal mountings about it, and all steel instruments such as knives, scissors, or forceps must be kept away from the solution or it will quickly corrode them. If the solution contains too much chloride of mercury a white crystalline deposit will be left on the specimens. But we say again emphatically that in this country ' the game is not worth the candle.' If further proof be needed it may be mentioned that the writer has in his own herbarium many hundreds of perfect specimens collected eighty or more years ago which were never ' poisoned/ but which have suffered nothing from the attacks of insects, and are to-day as complete and in as good condition as ever. It has been customary in this country to mount dried plants on paper by means of paste, good gum, or liquid glue. When fre- quently handled this may have its advantages, and especially if little envelopes containing loose portions of the flower and fruit are attached for careful examination or dissection ; but many amateur botanists attach their specimens to the paper with narrow strips of gummed paper, so that they can be examined on both sides, and altogether removed if desired. The little rolls of transparent adhesive paper sold by stationers for repairing torn music, books, etc., cannot be improved upon for this purpose. Another method 34 SUB-ALPINE PLANTS sometimes adopted on the Continent is to .attach the thin portions of stem, etc., to the paper by means of ordinary pins, of course placed horizontally. If gum be used it is best made of a mixture of gum Acacia (gum Arabic) and gum Tragacanth, it being both clean to use and very adhesive. In rare instances collections of plants are not mounted at all, but simply left loose in folded sheets of paper. However, they are better more or less mounted, and the paper should be a thick, white cartridge or some similar paper, which will remain rigid and flat when one end is held in the hand. After the plants are mounted they should be labelled. The labels should be about 3 J X 2 inches in size, of rather thin but good white paper so that they can easily be gummed or pasted in a corner of the mount. In British collections it is usual to have the name of the owner neatly printed at the head of the label after the contracted word ' Herb. ' (before which ' Ex. ' can be written when specimens are exchanged or given away). A broad space is then left for the name of the plant, and usually there are lines for the habitat and locality, and half-lines for the Vice-County, collector's name, date and number in the last edition of the London Catalogue of British Plants. But for European herbaria a simpler label is usually adopted, with the same simple line border, and either with the heading ' Herbarium Europaeum, A. B.C.— -' or ' Flora of Switzerland/ ' Plants of Norway,' or something of that sort. It saves time when many specimens have been collected by the same person to have the collector's name, preceded by ' Coll. ' or ' Legit/ printed in small type at the base of the label. It should have been mentioned that in mounting many specimens which do not fill a sheet, it is important not to place them always in the centre, but rather at one side if narrow, or in one corner if very small. This will not only tend to keep the bundles of sheets fairly level, but allow several examples of the same species from other districts or from other countries to be added later. The label should, of course, be placed near the plant, and it is sometimes well to rule off with a pencil line one specimen from another from a different district. In this way it is quite easy to have four or five gatherings of the smaller Alpine plants with different labels mounted on the same sheet. In starting a continental collection young botanists are tempted to economise in paper and space by mounting different species on the same sheet. This is greatly to be dis- couraged, for, apart from the want of systematic order, the space may be needed on future occasions for plants of the same species or variety. As previously suggested, it is an excellent plan to have a series of very small envelopes, which can be home-made, in which to keep seeds, fruits, and sometimes individual specimens of the flowers or even some leaves, so that they can be easily examined either ON COLLECTING AND PRESERVING PLANTS 35 with an ordinary pocket-lens or under the microscope. Such en- velopes should be gummed at the back to the sheet of mounting- paper, preferably with the name of the plant and its collection number, if any. These field numbers are quoted, and save much trouble and needless explanation in the event of any subsequent correspondence on the specimens they refer to. In collecting obscure forms and little known varieties and all plants such as Hawkweeds, Willows, Roses, Sedges, etc., in any quantity, all of one gathering should bear the same numeral. This is particularly the custom with collectors of sets of rare plants in new or little- known countries, and these numbers are referred to and quoted afterwards in books written on the flora of those countries. In working at any special genus or at the plants of one country, whether it be at Petersburg, Vienna, London, or New York, it is a great help to find a collector's specimens all uniformly numbered thus. The arrangement of the specimens in genus covers, and of the herbarium generally in a cabinet, must depend upon the individual taste of the botanist and upon the size of his collection. But except in very small collections when several genera can be placed together in one cover, with its name and that of the various genera neatly written outside, it is better to place all the species of one genus only in a cover. These genus covers should be made of stout brown paper folded to a slightly larger size than the mounting paper. The name of the genus should be written on the end of the cover so that it can be readily found when packed in the cabinet. As the collection grows it may be necessary to have more than one cover for many of the larger genera. Cabinets should be made of well-seasoned wood — what is called American whitewood is a very good and inexpensive material. The usual form is a tall, upright cupboard, divided perpendicularly into two equal parts, and with two closely fitting doors opening in the middle (two doors are very much better than one). The shelves should be made very carefully of thin wood which will not warp, and they should slide easily in shallow grooves cut in the framework of the cupboard. They are better supported in this way than on narrow strips of wood nailed to the sides, for such strips interfere with the papers when the shelves are very full.

Distribution. — Eastern, Central and Western Alps ; in Switzer- land only in Grisons ; Eastern and Central Pyrenees, Caucasus, Northern Europe and Asia (British). In Norway it reaches about 3400 feet. Thalictrum fcetidum L. Rhizome short. Stem 4-12 inches high, flexuous, feebly striated, glandular pubescent, and foetid like the whole plant. Leaves as broad as long, somewhat triangular ; leaflets small, toothed, usually densely pubescent, rarely glabrous ; foliage like Maidenhair fern except in colour. Flowers yellow, pendent, in a much-branched panicle. Carpels rounded at the base, oval-orbicular with prominent ribs. Another polymorphic species found in rocky places among the mountains up to 8000 feet. June to August. It is very common about Zinal. Distribution. — Alps of Central Europe, Eastern Pyrenees, Central and Northern Asia. Thalictrum tuberosum L. Roots tuberous, spindle-shaped. Plant distinguished from all other species of Thalictrum by its flowers having 4 or rarely 5 large yellowish white sepals. Dry, rocky places up to 4000 feet in the Pyrenees, Corbieres and Spain. The European species of Thalictrum are easily naturalised in RANUNCULACE^: 49 Britain in almost any soil, and readily increased from seed or by division in early spring. T. aquilegifolium is particularly ornamental in gardens, and likes shade and a light soil. \ ANEMONE L. Rootstock perennial. Leaves radical. Involucral bracts com- pound and often leaf-like. Flowers usually solitary. No petals. Sepals 5 or more, coloured and petal-like, longer than the stamens, which are numerous. Carpels numerous, i-seeded, often ending in a long feathery awn. A large genus of some 85 species, found in most of the temperate regions of the world, and chiefly characterised by the three ' leaves ' placed in a whorl from half-way up the stem to very near the flowers, according to the species. Anemone Hepatica L. (Plate IV.) Root short, fibrous. Stem naked, velvety. Leaves leathery, heart-shaped at the base with 3 equal lobes, often purple below, persistent and with long petioles. Flowers blue, rose, or white, solitary. Involucre of 3 oval, entire leaflets, resembling a calyx. Sepals 6-9, glabrous. Carpels covered with tomentum, with short, glabrous beak. The blue form is the commonest, and it is abundant in shady places and woods among the hills, especially on Jurassic limestone. In the Eastern Pyrenees it flourishes from about 2500-4500 feet. March to June, according to situation. Distribution. — Nearly all Europe ; Siberia, North America. In Mr. Flemwell's Alpine Flowers and Gardens, where is a most delicate picture of Hepatica in the woods at Bex, in the Rhone Valley, he says : ' As the snow recedes, the brown bed of the pine forests is decked with myriads of Hepatica ; their thick clusters of mauve- blue blossoms, relieved here and there by the rarer forms of white and rose, glint gaily among the sombre tree-trunks, creating a veritable laughing fairyland where, usually, all is sedate, if not actually gloomy.' In gardens it likes a deep, light soil, with some leaf-mould, and should be disturbed as little as possible. Anemone narcissiflora L. Rootstock oblique, premorse, with branching fibres. Stem erect, 4-12 inches high, simple, with several leaves at the base, villous like the leaves, and bearing a terminal 3-6 flowered umbel. Root- leaves stalked, palmate, 3-5 partite, sparsely villous or glabrous on the upper side ; the segments usually doubly 3-cleft. Bracts 3-4, sessile, smaller and less divided than the root-leaves and often only 2-3 cleft. Sepals usually 5, glabrous on both sides. Flowers white, often tinted with pale rose, f to i J inch in diameter ; seed- vessel erect. Carpels not bearded, very shortly beaked. 50 SUB-ALPINE PLANTS Alpine pastures and steep, partially wooded banks and hillsides ; but nearly always on calcareous soil, from 3000 to 6800 feet, and often covering large tracts. End of May to August, according to situation. Distribution. — Eastern, Central and Western Alps ; Erzgebirge, Vosges, Jura, Pyrenees, Transylvania, Balkans, Caucasus, Western and Central Asia ; Steppes of Russia and Siberia ; North America. This beautiful Anemone likes rich, loamy soil, with plenty of leaf -mould mixed with lime. Care should be taken to get up the whole root of this and other members of the genus if success is to be expected from collected specimens. Anemone apennina L. Root tuberous, blackish. Stem 6-10 inches high, slender, glabrescent. Leaves resembling those of the common Wood Anemone ; bracts of the involucre petioled, having the appearance of leaves. Peduncle erect. Flowers pale blue, solitary. Sepals 10-15, almost linear. Carpels shortly pubescent, elliptic, with glabrous beak. Woods and rocky places. April. Distribution. — Southern Europe ; Italy, Corsica, Dalmatia, Herzegovina, Montenegro, Corfu. Occasionally it is found in plantations and woods in England, but is certainly not native. It looks best in large clumps, and is a very ornamental plant for open shrubberies and glades, and for establishing round the base of some tree which will allow the sun to open its flowers in spring, but protect it from the fiercer heat of summer. A top-dressing of leaf-mould and peat is beneficial. Anemone nemorosa L. Wood Anemone. Rhizome horizontal, nearly black, sending up 2 or 3 leaves at the extremity and a single flower-stalk, either glabrous or slightly downy. Leafstalks long, with 3 ovate or lanceolate leaflets, toothed or lobed. Peduncle 3 to 8 inches high, with involucral leaves at about two- thirds of its height, smaller, and on shorter stalks than the real leaves. Sepals 6, white, often bluish or pinkish outside, glabrous. Carpels downy, longly pointed, but not feathery. Woods of the sub-alps and plains, damp meadows and broad hedges. March to May. Sometimes seen growing in Switzerland up to 6000 feet, as e.g. on the Simplon Pass, where in June, 1908, we found it accompanied by the Sulphur Anemone. The colour of the sub-alpine forms is generally deeper than that of the plains. Distribution. — Nearly all Europe ; North - west Asia, North America. Abundant in Britain. Anemone ranunculoides L. Rhizome horizontal. Stem and whole plant about the size of the 4/7 NATURAL SI/K PLATE IV. i. PHYTKUMA HKTOXICI FOLIUM. 2. GXAPHAl.IUM SYI.YATICUM. 3. PHYTKUMA SPICATUM. 4- ANK.MOXK HKPATICA. s. I'HYTKU.MA OR1UCUI.ARK. RANUNCULACE^: 51 Wood Anemone, which it much resembles in habit as well as in habitat. Leaves spring far from the stem, with 3-5 shortly petioled segments ; leaflets of the involucre shortly petioled and resembling true leaves. Flowers bright yellow, usually solitary, but some- times in twos or threes. Sepals 5-8 oval. Carpels pubescent, with long glabrous beak. Woods and meadows, and damp, shady places, and by streams, especially on a limestone soil. March to May. Distribution. — Throughout France, including the mountains above the Riviera, though rare elsewhere in the South, and fairly spread through Europe, though rare in Switzerland except in the Jura ; Western Asia. Occasionally found in England and the south of Scotland, but is probably not indigenous. It is a useful plant to naturalise in shrub- beries, but in this country it is rarely seen so fine as on the Continent, as, for example, in Savoy, in the neighbourhood of Aix-les-Bains,etc. Anemone sylvestris L. Root short with matted fibres. Stem 10-20. inches high or more, slender, downy. Leaves downy, cut into 5 rhomboidal segments, bi-trifid, toothed irregularly. Leaflets of the involucre stalked, resembling true leaves ; peduncle always erect. Flowers white, large, solitary. Sepals 5-8, oval, silky outside. Carpels woolly, numerous, forming a tight oblong head. Woody places and stony hills ; rare. May, June. Distribution. — North of France, Alsace-Lorraine, Central Europe, Southern Sweden, Caucasus, Russia, Western Asia. In Switzerland only in Canton Bale. A very ornamental plant for the borders of shrubberies and shady places in gardens ; and it looks particularly well with large ferns in a rockery. Anemone trifolia L. Radical leaves usually wanting at time of flowering. Involucral bracts 3, petioled, with simple, broadly lanceolate and regularly serrated segments. Flowers solitary. Sepals usually 6, oblong, glabrous beneath, white, but very rarely blue (var. ccerulescens Hausm.). Bushy places and woods up to about 5500 feet. June, July. Distribution. — Southern Tyrol to Carinthia, where it is often abundant. Woods, pastures, and chestnut-groves in Liguria, at about 2000 feet. According to Moggridge it replaces A. nemorosa along the coast from San Remo to Genoa, while the Wood Anemone usually grows higher among the mountains (Flora of Mentone, etc.). Anemone alpina L. Rootstock thick, and extending into a long, fibrous tap-root. Stem 6-18 inches high. Root-leaves ternate, bipinnatifid, with 52 SUB-ALPINE PLANTS deeply cut segments. Involucral bracts ternate, shortly stalked, and resembling the root-leaves. Flowers solitary, white, often tinged with blue below, large, but variable in size, and blossoming before the leaves are fully developed. Sepals usually 6. Carpels, as well as the very long awn or beard, villous. The heads of feathery seeds of this and A. sulphur ea form conspicuous objects in late summer. The seeds are at first reddish brown, and arranged spirally, and they all turn upwards stiffly ; then they gradually bend hori- zontal and downwards, and the colour becomes a dull mauve. Pastures and rough ground on steep slopes in the Alps and sub- Alps, especially on calcareous soil. May to July, remaining till August in the higher situations. Distribution. — Carpathians, Eastern, Central and Western Alps, Vosges, Jura, Auvergne, Erzgebirge, Pyrenees, Corsica, Caucasus, North America. Anemone sulphur ea L. (Plate V.) Probably only a variety of A. alpina, but usually growing on 'the older siliceous and granite rocks. The flowers are a pale, clear yellow colour and often larger than those of the white one. The habitat and distribution, except as to geological formation, are fairly similar to the last. The seeds, collected in August usually, are difficult to germinate, but sometimes come up the second year when sown in the autumn in good, peaty soil, watered with a fine spray, and screened from the sun in a greenhouse or cold frame. As suggested in the Gardeners' Chronicle in 1910, and in Alpine Plants of Europe, we again recommend that this Anemone be tried in flower beds, and also in turf and rough pastures in parks, etc., for clumps of these beautiful flowers would look remarkably well. But the plant dislikes lime, and probably for that reason it does not appear to be found in the Jura mountains. Specimens with double flowers were recorded many years ago from between Saas and Monte Moro, having been found by the Rev. T. Butler near the Mattmark See. Anemone vernalis L. Stem 3-5 inches high, silky. Leaves pinnate, shaggy ; leaflets broadly wedge-shaped, in 2-3 pairs, 3-cleft, the divisions ovate, entire, or 2-3 toothed. Involucre of 3 sessile, multipinnate bracts, villous, with yellowish red hairs. Flowers large, nearly erect. Sepals connivent, white within, reddish, and finally bluish on the outside, villous, with yellowish red hairs. Carpels oblong, villous, with long plumose beak. It opens its flowers immediately after the snow has melted, but when fertilised they are usually closed again. Dry Alpine and sub-alpine pastures, 3500-9000 feet. April to July. Rather local and preferring siliceous soil. Pl.ATK V. i. LINARIA ALPINA. 2. LINARIA PETR/KA. 4. POLVGALA CHAM.tBUXUS. 6. ANEMONE PULSATILLA. 4/7 XATUKAL SIZE. ERIOPHORUM VAGINATUM. DIAXTHUS SUPERBUS. ANEMONE SULPHUREA. RANUNCULACE^: 53 Distribution. — Eastern, Central, and Western Alps ; Pyrenees, Riesengebirge, Alsace-Lorraine, North Germany, Carpathians, Scandinavia, Siberia. In Norway it reaches the limit of eternal snow. Anemone Halleri All. Stem taller than the last. Plant villous, with white, shining glandular hairs. Leaves pinnate, with segments in 2-3 pairs, pinnatifid, the lobes 2-3 cleft ; ultimate segments entire or 3-cleft. Bracts of involucre sessile, linear-lanceolate, very hairy. Flowers usually pale violet, rarely white or rose-coloured, large, erect, solitary. Sepals 6, elliptic, silky outside. Carpels with long plumose beard. Southern slopes and dry pastures at about 5000 feet, though occasionally descending lower. It usually blooms in May and June. Distribution. — Carpathians ; Eastern Alps, Switzerland (only in Valais), Savoy, Dauphiny, Provence, Italian Alps, Poland, Southern Bohemia. Anemone Pulsatilla L. Pasque-flower. (Plate V.) A smaller plant than the last. Leaves deeply cut into linear segments, and the whole plant very hairy. Flowers large, solitary, erect or finally drooping, purple. Carpels with a long plumose beard. A very acrid plant with medicinal properties. Dry, stony, sunny places, especially on chalk and limestone. It frequents the lower hills rather than the mountains. March to May. Distribution. — Almost all Europe ; Siberia. In Britain confined to a few chalk hills in the south and east of England. Local in Switzerland. Anemone montana Hoppe. Plant 6-12 inches high, covered at first with silky hairs, later almost glabrous. Leaves with linear segments. Petiole broadened into a sheath at the base. Flowers solitary, dark violet, drooping, very silky outside ; bell-shaped at first, star-shaped later, darker in colour and smaller than those of A. Pulsatilla. Rarely the flowers are blue, rose or whitish. Sunny, stony places on the hills and lower Alps up to about 6500 feet — local. March and April. Autumn flowering specimens were found by the author near Sierre in the Rhone valley in 1911. Distribution. — Switzerland, Dauphiny, Auvergne, S. Tyrol and Transylvania. ADONIS L. Pheasant's Eye. Characters those of Ranunculus, except that the petals have no nectary, though often deeply coloured at the base, and the seed is suspended and not erect, in the carpel. Leaves with very narrow7 segments. 54 SUB-ALPINE PLANTS A small genus, chiefly confined to Southern Europe and Western Asia. Adonis vernalis L. Stem about a foot high, almost glabrous ; lower leaves reduced to scales, the others herbaceous, multifid, with linear segments. Flowers pale yellow, large, petals 10-15, lanceolate or oblong. Carpels oval, rounded, pubescent, with short recurved beak. Sepals pubescent. Dry pastures, stony or wooded. April, May. Distribution. — In several places in the Valais ; Cevennes, Alsace, Spain, Central and South-Eastern Europe. Both the late A. W. Bennett, in his Flora of the Alps, and F. E. Hulme, in Familiar Swiss Flowers, were in error in stating that this is a weed in cultivated ground in Switzerland. If on cultivated land it has been planted for sale in the market. Adonis pyrenaica DC. Stem about a foot high, slightly hairy ; leaves all herbaceous, the lower ones large and longly petioled, 3-4 pinnate with linear segments. Flowers bright yellow ; petals 10-15 oboval. Carpels angular, pubescent, with long, tapering, recurved beak. Rock and cliffs ; rare, 5000 to 6500 feet in the Eastern Pyrenees. June, July. Distribution. — French and Spanish Pyrenees ; and in one or two places in the Maritime Alps. Adonis autumnalis L., with deep red petals, often with a black spot, and A. czstivalis L., with red and sometimes yellow flowers and glabrous sepals are annuals sometimes found among crops and in waste places in the mountains ; but they cannot be con- sidered sub-alpine. We have specimens of A. cestivalis from Mont Cenis, at about 6300 feet above the sea. RANUNCULUS L. Buttercup. Annual or perennial herbs, sometimes entirely aquatic. Leaves entire or more or less divided. Flowers usually yellow or white. Sepals 5, very rarely 3. Petals 5 or more, each with a thickened hollow spot at the base, often covered by a minute scale. Stamens numerous. Carpels numerous, without awns, in a globular or oblong head, each with a single ovule attached near its base. A large genus, spread widely over the temperate regions of the globe, and even found in the tropics. Ranunculus aconitifolius L. (Plate VI.) Rootstock short, premorse, tufted with thick fibres. Stem erect, 1-3 feet, leafy, branched above, 3-many-flowered, flexuous, glabrous like the leaves or with a few scattered hairs. Root-leaves and lower RANUNCULACE^E 55 stem-leaves stalked, developing before the flowers, palmate, 3-7 cleft ; segments 2-3 cleft, or undivided, unequally serrate, acute ; stem-leaves more shortly stalked or sessile, less divided, less serrate. Flowers forming a terminal cyme. Petals white, obovate, obtuse. Carpels veined and furrowed, large, glabrous, with a short curved beak. The sepals, which envelop the buds before opening (when they fall) are a beautiful purplish colour. Very variable, both in the height of stem and in the numbers of leaves and flowers. The leaves are thin and dark green. The variety platanifolius L., commoner in the Eastern Alps, has a tough, not zigzag stem and glabrous peduncles. In Norway it is found up to the birch limit. Wet meadows, borders of streams, and shady, stony places, in clefts of rocks and by springs in the mountains ; and often brought down to a low elevation by mountain torrents. June to August. 2000-8000 feet. In cultivation it does best in cool, damp, rocky places under trees, and can be associated with such vigorous plants as Adeno- styles, Achillea macrophylla, Mulgedium alpinum, etc. Distribution. — Eastern, Central and Western Alps; Carpa- thians ; Sudetic Mountains ; Black Forest ; Vosges ; Jura ; Cevennes ; Corbieres and Pyrenees ; Corsica. Ranunculus crenatus W. et Kit. Stem erect, 3-6 inches high, usually i-leaved and i-flowered, glabrous. Leaves roundish cordate or reniform, undivided or slightly 3-cleft near the apex, crenate ; stem-leaves linear. Flower- stalk furrowed. Calyx glabrous. Flowers white. Petals obovate, with wavy margin, crenate. Achenes smooth without any mem- branous margin, glabrous, globular, drawn out into a striated hooked beak. August. Distribution. — Meadows on primitive rocks, 3500-6800 feet, rare ; Carpathians, Styria, and Eastern Alps. Ranunculus alpestris L. Rootstock cylindrical, oblique or vertical, tufted, covered with thick fibres. Stem erect, 2-4 inches high, leafless or 1-2 leaved, simple, usually i-flowered, glabrous like the entire plant. Root- leaves stalked, cordate-rounded or reniform, undivided or digitate, or cleft and coarsely crenate, appearing before the flowers. Stem- leaves smaller, linear or wedge-shaped, entire, obtuse, sessile, the base broader and membranous at the margin, leaves somewhat rugose, shining on the upper side. Flowers snow-white. Petals usually 5, obcordate, often 3-lobed. Achenes smooth, glabrous, with a long-hooked beak. Locally abundant (especially on calcareous soil) in pastures and damp, stony places on the Alps from 4600-8500 feet. June, July. 56 SUB-ALPINE PLANTS Below the famous Joch Pass, leading from Engelberg to Meiringen, the damp rocks and stony pastures at about 7000 feet are in July purple and white with myriads of blossoms of Primula integrifolia and R. alpestris. But directly one gets west of Switzerland this buttercup becomes rare. Distribution. — Carpathians, Eastern and Central Alps ; rarely in Savoy and Dauphiny ; Jura, Eastern and Central Pyrenees. R. alpestris can be planted in a mixture of peat, loam, and leaf- mould, with a little grit added, but the place must be well drained and with a little shade. Snails must be kept off in the early spring, as they are fond of eating the crowns when just appearing. Ranunculus Traunfellneri Hoppe. Stem 1-3 inches high ; leaves not shining, where it differs chiefly from A. alpestris, which it resembles, and of which it is sometimes considered a variety. Leaves veined ; root-leaves 3-partite, reni- form in outline, the central lobe 3-cleft, the divisions lanceolate. Stem i-flowered, usually with one leaf ; stem-leaf linear, undivided. Flower-stalk furrowed. Calyx glabrous. Petals obcordate or 3-lobed, white. Dry places on limestone, at about 5000 feet ; rare. June, July. Distribution. — Eastern Alps ; Tyrol to Carniola.

Very variable, and with several named varieties, of which R. Villarsii DC. is a very striking^dwarf form. Distribution. — Carpathians, Eastern, Central, and Western Alps, Jura, Black Forest, Corbieres, Pyrenees, Western Asia and W. Africa. Ranunculus lanuginosus L. A tall Buttercup, the size of R. acris. Stems hollow branched, densely woolly. Leaves hairy beneath, lower ones 5-partite with broadly obovate lobes, irregularly toothed, the upper leaves tripartite with lanceolate lobes ; peduncles not furrowed. Flowers bright yellow. Sepals spreading, hairy ; receptacle glabrous. Carpels glabrous, with hooked beak nearly half the length of the carpel. ^Mountain woods, especially in the Conifer zone. June to August. RANUNCULACE^: 57 Distribution. — Alps, Jura, Dept. of the Var, Corsica ; Central and Southern Europe from Denmark to Italy, Greece and the Caucasus. Ranunculus bulbosus, R. acris, and R. repens are often found in the sub-alpine meadows ; R. acris especially ascending some distance into the mountains. R. auricomus does not get higher than the woods of the Swiss foot-hills. Ranunculus Thora L. Rootstock with spindle-shaped roots in bundles. Stem 4-12 inches high, 1-5 flowered, simple, glabrous like the whole plant. Lower stem-leaves sessile or shortly petioled, roundly kidney- shaped, toothed or crenate-toothed, the next leaves with 3-5 lobes, and the others lanceolate entire. Flowers small, yellow. Petals 5. Sepals glabrous. Carpels almost globular, with a short beak. Steep, stony places in the Alps, in the Pine region and above, up to 7000 feet. June, July ; not common. Distribution. — Carpathians, Eastern Alps, Switzerland, Jura, Savoy, and Dauphiny ; Italian Alps and Central Pyrenees. Ranunculus scutatus Schott. This species closely resembles the last, of which it is considered a variety by some botanists. It is taller and stouter, with more branched stem and larger flowers. Its habitat is similar, but it is not found quite so high in* the Alps. June, July. Distribution. — Eastern Alps (Styria). CALTHA L. 4 Flowers regular. Sepals usually 5, large and yellow, petaloid, no real petals. Stamens numerous. Carpels 5-10 compressed, each with several seeds. A very small genus, inhabiting the temperate and cold regions of both northern and southern hemispheres. Caltha palustris L. Marsh Marigold. Stems about a foot long, often rooting at the lower nodes. Leaves mostly radical, on long stalks, orbicular or kidney-shaped with cordate base and crenate margin, very glossy. Flowers large and handsome, bright yellow. Marshy places, by streams, and damp mountain slopes from the plains up to 8000 feet, and very abundant in the lower Alps from 3000 to 5000 feet. In Norway to 4300 feet, or above the birch limit.

America, besides the European species. Trollius europceus L. Globe-flower (Plate X.) Stem erect, ij-2j feet, simple and i-flowered or branched and 2-3 flowered, glabrous like the whole plant. Leaves palmately 5-cleft, lower ones stalked, upper leaves sessile ; divisions rhom- boidal, 3-cleft, unequally cut. Sepals yellow, almost closed into a ball. Follicles glabrous, linear, obliquely wrinkled, turning black when ripe, seeds black. Damp Alpine and sub-alpine meadows and mountain declivities, often in great masses, sometimes extending to 8000 feet in altitude. In Great Britain it is almost confined to sub-alpine districts in the north and west ; but it actually descends, or did fifteen years ago, the valley of the Taff to within a mile or two of the town of Cardiff. May to July. Distribution. — Carpathians, Eastern, Central, and Western Alps, Black Forest, Vosges, Jura, Auvergne, Cevennes ; Corbieres and Pyrenees ; Europe, especially northern and central, as far as the Caucasus. It grows freely in almost any soil, and thrives in a stiff loam with a moist subsoil. Globe-flowers rarely vegetate until the spring following the year in which the seeds are sown, but they do not attain full development until about the fourth year. HELLEBORUS L. Hellebore. Perennial herbs with palmately or pedately divided leaves. Sepals 5, large, often greenish, remaining till the fruit is nearly ripe. Real petals 8-10, very small, tubular. Stamens numerous. Carpels several, large, with several seeds. Helleborus niger L. Christmas Rose. Rootstock thick, oblique, knobbed, with black fibres. Stem erect, simple, glabrous like the whole plant, 3-6 inches high, usually I, rarely 2-flowered, leafless, having 2 or 3 elliptical or ovate bracts in the upper part. Leaves radical, large, coriaceous, stalked, pedate, 7-9 cleft ; divisions undivided or 2-3 cleft, linear-lanceolate or wedge-shaped, acute, toothed. Flowers nodding, handsome, 2-3 inches in diameter, white or rose-tinted, ultimately green. Petals and stamens yellow. Sepals petaloid, elliptical. Follicle (capsule) elongate, obliquely veined, with a long beak. The leaves spring up after the flowers, but remain through the RANUNCULACE^: 59 following winter. The rootstock contains a narcotic poison of a very fatal character. It is officinal. Calcareous sub-alpine woods and rocky, wooded slopes, as high as the zone of Pinus montanus. January to April. Distribution. — In Switzerland only in Canton Tessin. It is fre- quent in woods above Lago Lugano < Carpathians and Central Europe from Tessin to Roumania. If deep cultivation is given on planting, Helleborus niger seems indifferent to subsequent treatment, provided it is not much disturbed. Lifting and dividing should be done in July, when the plant is strongest. Though garden specimens are often protected by a hand frame before and during flowering, the Christmas Rose sometimes suffers when removed from under glass, for though very hardy the protection of a glass tends to bring on the young foliage before its time. Helleborus viridis L. Green Hellebore. Plant 10-20 inches high. Radical leaves large, on long stalks, divided into 7-11 oblong, acute, toothed segments, 3-4 inches long, the central ones free, the lateral ones connected together at the base. Flowers 2-4, large, drooping, yellowish green. Woods and hedges, especially on limestone, and about old buildings in the plains and hills. March, April. Distribution. — Western and Central Europe (British). Helleborus fcetidus L. Foetid Hellebore. About 2 feet high, robust, with perennial leafy stems. Lower leaves not all radical, but forming a larger and thicker tuft than in H. viridis. Segments narrower, less toothed, and more shining. Flower-stem about a foot high, with a large close panicle of droop- ing flowers, of a pale green tinged with purple. Common in stony pastures, chiefly in limestone districts, and sometimes in great masses on mountain slopes, such as those of the Jura. February to May. Distribution. — Western and Central Europe as far as Styria. Spread through France, but rare in England. Helleborus lividus Ait. (H. corsicus Willd.). This handsome species has prickly leaves divided into 3 lanceo- late segments, and white or rose-coloured flowers with spreading sepals. Distribution. — Mountain region of Corsica, Sardinia, and the Balearic Isles. November to April. 60 SUB-ALPINE PLANTS ERANTHIS Salisb. A genus of only 5 species inhabiting the mountains of Europe and Asia. Flowers regular. Sepals petaloid, deciduous. Petals small, 2-lipped. Eranthis hiemalis Salisb. Winter Aconite. Yellow petals and sepals. Flowers solitary and sessile in an in- volucre of green ' leaves.' Leaves glabrous, shining, appearing after the flowers, orbicular, but deeply cut into segments. Sepals petaloid, 5-8. Follicles 5-8, free, divergent, with a beak half their length. Damp, wooded places, sometimes extending up to 5000 feet in the Alps, though very local. February and March. Frequently naturalised in shrubberies, etc., in Switzerland and Normandy, and well known in English gardens. Even in 1633 Gerard wrote, "We have great quantities of it in our London gardens." Distribution. — Vosges, Jura, Alps of Dauphiny and Provence ; Central Europe as far as Servia. In Switzerland it is rare, and only naturalised in orchards, vineyards, etc. AQUILEGIA L. Columbine. Perennial herbs with the leaves mostly radical, ternately divided, with distinct stalked segments or leaflets. Sepals 5, coloured. Petals 5, each prolonged below into a horn-shaped spur. Stamens numerous. Carpels 5, each with several seeds. A small genus, spread over the temperate regions of the northern hemisphere, especially in hilly districts. Aquilegia alpina L. Alpine Columbine. Stem 1-2 feet high, 1-3 flowered. Leaves doubly ternate ; leaflets deeply incised and 3-cleft, crenate. Flowers very large, the petaloid sepals broadly ovate, deep blue, the spur of the nectary somewhat curved. Petals 5, broad, paler blue, rather longer than the stamens. Follicles 5, densely hairy. One of the most handsome plants of the Alps. Mr. Reginald Farrer says of it in My Rock Garden, page 46 : " The flowers, dancing high on airy stems, are of enormous size, most exquisitely, daintily balanced, and of a soft, melting blue quite impossible to describe — a colour deep yet gentle, brilliant yet modest, perfectly clear and yet not flaunting." The same writer, in speaking of the cultivation of Columbines, tells us : " The essential is to give them perfect, quick drainage, and then a soil both rich and light. They dislike, too, being battered by winds and weather when they are coming up. The best that we can do is to remember how they lodge and dodge behind bushes on their native hills when they can, and give them some such similar protection in the garden." RANUNCULACE^: 61 Rocky, bushy places and escarpments in the Alps ; 4500-6500 feet. July, August. Scattered and generally rare. Distribution. — Switzerland, where it attains its eastern limit in the Engadine ; Alps of Savoy, Dauphiny, and Provence ; Mont Ventoux and Northern Italy. Aquilegia Einseleana F. Schulz (A. pyrenaica Koch, not DC.). Stem 6-12 inches high, tender, more or less covered with viscid, glandular hairs, especially above.

June, July. Distribution. — Western Alps only, as Hautes-Alpes, Basses- Alpes, Maritime Alps, Var, Liguria, and Piedmont ; abundant in some of the Ligurian and Maritime Alps, at from 2400 to 5500 feet, where it takes the place of A. alpina. Aquilegia vulgaris L. Common Columbine. Stem 2-3 feet high, pubescent, branched above. Lower leaves longly petioled, usually biternate, with broad incised segments ; upper leaves sessile, with lobes often entire. Flowers purple, rarely white or rose, large, longly peduncled. Woody places and rough hilly pastures, especially on lime- stone, from the plains up to 5000 feet. May to July. 62 SUB-ALPINE PLANTS Distribution. — Nearly all Europe ; Siberia, Himalaya. In- digenous in parts of the British Isles, but often introduced. Aquilegia atrata Koch. This is probably a variety of the Common Columbine, with violet-black flowers about an inch in diameter, which occasionally grows at about 5000 feet in the Italian Maritime Alps and the Jura, and flowers in June and July. The stamens are longer than in the common Aquilegia. Hoffmann speaks of its being " widely, and in some places abundantly, distributed over the Alps and sub-Alps, and regarded by many botanists as an Alpine form of the Common Columbine " ; but he and some other botanists include in this category the ordinary mountain plants with " purple-brown " flowers, which are so common and so decorative in many Alpine pastures, as e.g. those about Engelberg. The Alpine species of Aquilegia are rather more difficult to cultivate than the common one, and they are best sown from seed in spring obtained direct from the Alps, pricked out into pans or a cold frame, and planted in early autumn in deep, well-drained loam with some grit in it. On rockeries they do well in half-shady but well-drained positions, but A. alpina likes rather more sun. DELPHINIUM L. Larkspur. Mostly annual herbs having much divided leaves with narrow segments. Sepals 5, coloured and spurred. Petals lengthened into a spur. Carpels 1-5 each with several seeds. A considerable genus, widely spread over the northern hemi- sphere without the tropics.

Flowers yellow. Ovary i -celled. Capsule linear, valves thin. Only 2 species. They extend from Europe to Japan. Chelidonium majus L. Greater Celandine. Though more strictly a plant of the plains, this well-known herb, with yellow flowers and handsome leaves and yellow juice, is not infrequently met with in the sub-alpine region, though even there it is usually in the neighbourhood of houses as, e.g. close to the villages of Evolene and Zinal in the Valais. The recently published coloured prints of Chelidonium, after the beautiful work of Albrecht Diirer 400 years ago, show the accuracy of form and colour that great master possessed. FUMARIACE^: 69 FUMARIACE^: Flowers irregular. Sepals 2, deciduous. Petals 4, one or two of them gibbous or spurred. Stamens 6, in two bundles of -3 each. Ovary i -celled.

An extensive family widely spread over the globe, but chiefly in the northern hemisphere. The characters of the genera are chiefly derived from the pod and seed ; therefore to name a Crucifer it is almost necessary to have the specimen in fruit. ARABIS L. Annuals or perennials, usually erect and hairy, at least at their base, with a spreading tuft of radical leaves, which are occasionally lobed ; the stem-leaves undivided, sessile or clasping the stem. Flowers white or purple. Pods long and linear, the stigma nearly sessile, the valves flat or slightly convex. Seeds more or less flattened, often winged. A large genus spread over the temperate regions of the northern hemisphere. Arabis alpina L. Alpine Rock-cress. Stem 3-12 inches high, covered like the leaves with forked hairs.

Distribution. — Eastern Alps, Bavaria, Bohemia, Silesia ; Central Europe from the Jura to Italy, and Transylvania. Very local in Switzerland (Chasseral, Bex, etc.), and in France only known from Mont Pouillerel in the Jura. On rockeries it is easily grown in shady places and, owing to its creeping habit, it soon covers a large area, and must be kept in check. Cardamine asarifolia L. A glabrous, bright green plant. Stem leafy, i-ij feet high. Leaves all simple, cordate-orbicular, coarsely dentate, shining. 74 SUB-ALPINE PLANTS Flowers white, rather large. Anthers violet. Pods erect, twice as long as the stalk.

In England in some of the ' home counties.' Cardamine pentaphylla R. Br. (Dentaria digitata Lamk.). This is a smaller plant with no bulbils. The leaves are digitate and divided into 3-5 leaflets, which are oblong-lanceolate and toothed irregularly. Flowers rose or lilac. Siliqua erect, spreading. Rootstock fleshy, scaly. Figured in Curtis's Bot. Mag., tab. 2202 (1821). Mountain woods. May, June. Distribution. — Widely spread in Switzerland, and in France from the Jura and Vosges to the Pyrenees ; Central and Southern Europe. CRUCIFER^E 75 Cardamine pinnata R.Br. (Dentaria pinnata Lamk.).

D. cunea- phyllos L. with yellowish white petals and ternate leaves in whorls of three ; D. alternifolia Hausm. with yellowish white flowers and ternately-digitate leaves, and D. intermedia Sond. with lilac or white flowers and leaves quinately digitate. The Dentarias, as they are still commonly called, are useful spring flowers for shrubberies and shady borders. They do well in sand and peat or in sandy leaf-mould, and can easily be increased from the small tuber-like roots, or by planting the bulbils of D. bulbifera. MATTHIOLA Br. Stock. Annual or perennial shrubby plants covered with hoary tomen- tum. Leaves entire or sinuate. Flowers usually purple or lilac, never yellow, rather large. Petals spreading, on long erect claws.

T. virens Jordan is some- times considered a distinct species. Its leaves are a bright green and the flowers are larger than in alpestre. The style is also longer and more prominent. The anthers are violet and then blackish. It is usually found at higher elevations, at any rate in Switzerland. Thlaspi montanum L. A glabrous and glaucous plant, 6— 10 inches high, with stoloni- ferous shoots springing from the rootstock. Stem simple. Radical leaves oblong, petioled ; stem-leaves oblong, auricled or heart- shaped, sessile. Flowers rather large, Petals twice the length of sepals. Anthers pale lilac.

In England on Brean Down, Somerset, and near Torquay. Helianthemum vulgare Gaertn., H. Chamacistus Miller. Common Rock-rose. (Plate XL) A low undershrub, with short, much-branched, woody stem, and annual flowering branches from 3-10 inches long. Leaves shortly stalked, more or less oblong, but varying from ovate -to lanceolate, glabrous or slightly hairy, and more or less hoary beneath. Stipules linear-lanceolate. Racemes loose, the pedicels deflected. The 3 larger sepals marked with 3 prominent ribs, the 2 outer very small. Petals bright yellow, broadly spreading. Very polymorphic. Dry pastures and fields, from the plains to a considerable distance in the mountains. Above 8500 feet on the Col de Torrent, Switzer- land, in 1911. Very common. May to August. Distribution. — Nearly all Europe, Western Asia. England and Eastern Scotland, but apparently in Ireland only as a casual. Helianthemum grandiflorum DC. (H. virescens Gren. and Godr.). This is possibly only a large-flowered variety of the last, which assumes so many forms in the Alps. Flowers up to 26 mm. in CISTACE^E 89 diameter, solitary or in twos or threes. Leaves bright green on both sides and generally broader than those of H. vulgare. Dry Alpine pastures up to 7400 feet. June to August. This large-flowered variety is particularly fine at Mont Cenis, in Savoy and the Ligurian Alps. Messrs. Schinz and Keller in their Flore de la Suisse give two sub-species of H. vulgare, viz. H. barbalum Lam. and H. nummul- arium Miller. The leaves of the former are green and glabrescent, and those of the latter white-tomentose beneath. In the Ligurian and Maritime Alps there are two pretty rose- coloured plants which Mr. Bicknell l describes under H. vulgare : Var. roseum Burnat=£T. roseum Bert. Plant greyish by reason of the short hairs covering the stems, leaves, and pedicels. Flowers usually pink, rarely crimson or nearly white. Very common on dry banks in the littoral region. Var. semiglabrum Burnat=#. semiglabrum Bad.=#. Jacquini Ard. Leaves light green, narrow, and shining, the upper ones as well as the pedicels glabrous, or nearly so. Flowers pink. Not common in the littoral region. Val Nervia, etc. It is very common about Pigna in the Ligurian Mountains. Various other species grow in Spain and the Mediterranean district, among the foot-hills and lower mountains, several of which are worth cultivating. The Rock Roses are of the easiest culture in almost any light, rather poor soil fully exposed to the sun ; and they strike readily from cuttings. If cut back after flowering they tend to grow more compact. The hybrids are very numerous and many of them extremely beautiful, being in all shades of yellow, salmon-pink, rose, and crimson. Few plants are of greater value for the rockery, for in addition to their beauty they grow very quickly. The nomenclature, however, of this genus seems somewhat confused. The tendency to hybridise may partly account for this. FUMANA Spach. A genus closely allied to the last. The flowers are usually smaller and the habit shrubbier. The sepals are always 5, the 2 exterior being smaller ; and the capsule is 3-celled. Fumana procumbens Gren. et Godr. A recumbent small undershrub, 3-10 inches high, with woody base and branching stems. Leaves linear, sub-obtuse, mucronate, green, not stipuled, rough-edged. Flowers solitary, yellow, 1-4 on the upper part of the branches. Pedicels thick, deflexed, shorter J Flora of Bordighiera and San Remo (1896). 90 SUB-ALPINE PLANTS than the sepals. Valves of the capsules slightly open at maturity and containing 12 seeds. Dry screes and limestone rocks. Common. May to July. Distribution. — Central and Southern Europe as far north as the Baltic Isles ; Mediterranean region, Western Asia. In Switzerland locally in Tessin, Grisons, the Rhone Valley, and other warm places. On Monte Torraggio in Liguria we have seen this plant at some 4000 feet. VIOLACE.E A family represented in Europe by a single genus. VIOLA L. Leaves radical or alternate, stipulate. Flowers axillary, solitary, or in cymes, with 2 small bracts. Sepals 5, usually unequal, and produced at the base beyond their insertion.

" Approaches V. variata very closely and has often been confused with it " (Dr. E. Drabble). Meadows, rocky places, etc., in the sub-alpine region. May, June. Distribution. — Switzerland, Savoy, Norway. British. Figures of V. alpestris Jordan appear in an article by Dr. Eric Drabble on "The British Pansies" in Journal of Royal Hort. Soc.,1 xxxv. (1909), Pt. II. 1 "The flowers are yellow, and thus differ from the typical form of V. variata; but the latter may also possess yellow flowers, and it is such plants that have been confused with V. alpestris."— E. Drabble, loc. cit. POLYGALACE/E 93 Viola sylvatica Fries. Common Wood Violet. (Plate VII.) Leaves ovate, heart-shaped, acuminate, glabrous or with scattered hairs. Petals oblong, lilac or violet, the lower one shaded with darker colour. Stigma hairy on both sides and slightly arched beneath the top. Stipules linear-lanceolate, fringed-ciliate. Capsule glabrous. Woods, thickets, etc., up to 5000 feet in Switzerland and to 6000 feet in the Eastern Pyrenees. April, May. Distribution. — Europe, Asia from Siberia to Japan, Algeria, Canary Isles. British. POLYGALACE^E A family represented in Europe only by Polygala itself. The other genera being chiefly tropical and differ from Polygala in the form of the fruit, or, in minor details, in the structure of their flowers. POLYGALA Linn. Herbs or shrubs, with entire leaves, usually alternate, no stipules, and very irregular flowers in terminal racemes. Sepals 5, of which the two inner are larger, usually petal-like, and commonly called wings. Petals 3, 4, or 5, the lowest very small and subulate, and all more or less united with the stamens. Stamens united in two parcels. Style I, with a single stigma. Ovary and capsule flat, 2-celled, with a single pendulous seed in each cell. A numerous genus, widely spread over most parts of the globe. Some of the showy S. African species are often cultivated in our greenhouses. Polygala Chamcebuxus L. (Plate V.) Stem shrubby, creeping, branched ; branches prostrate or ascending, glabrous like the whole plant. Leaves narrowly lanceo- late or elliptical, entire, mucronate, the lower ones smaller, obovate. Flowers solitary or in pairs, terminal, or in the axils of the leaves. Corolla with a small, 4-lobed crest, as long as or shorter than the wing-sepals, which are ovate, oblique, erect or recurved, nerveless, with branched veins. Wings pale yellow before fertilization, often red, brownish or purple later. Corolla tube deep yellow, but pur- plish after fertilization. Woods and rocky or grassy places in the mountains, extending up to the Alpine region, where it is usually dwarfer and more floriferous. Very common. A difficult plant to get up by the long, slender roots, for they penetrate long distances, and yet there is little of them to survive a journey to this country. May to July. Distribution. — Central Europe from the Eastern Pyrenees to Roumania. Rare in the Jura. 94 SUB-ALPINE PLANTS This evergreen creeping shrub likes a shady place in sandy peat and loam, or in good leaf mould, and can be increased when well established by careful division. Poly gala alpinum Steudel. A small species, 2-4 inches high, with branched, recumbent stems. Leaves oboval or oblong, forming a rosette ; stem-leaves narrower and much smaller. Flowers pale blue, very small, in small, dense, terminal heads. Capsule small, rather shorter, but broader than the wings. Mountain pastures ; local. June, July. Distribution. — Western Alps, including Southern Switzerland, Pyrenees. Poly gala alpestris Reichb. Stems numerous, woody, filiform, spreading, ascending. Lower leaves short, broadly ovate, often forming a rosette ; upper leaves longer, clothing the lower part of the panicle. Flowers small, pale blue. Wings of calyx ovate, as broad as, and longer than the capsule. Alpine and sub-alpine pastures, especially on limestone. June, July. Distribution. — Juras, Central and Western Alps, including Piedmont. This species is not much understood, and is often confused with P. alpina Perr. et Long. P. alpestris may perhaps be a form of P. amara L., and it is synonymous with P. amarella Crantz var. alpestris Borbas. For the rock-garden there are other more beautiful species than the above which, though not Alpine, are more worthy of a place on rockeries. P. nicaensis Risso, a Mediterranean plant extending into the Maritime Alps up to 2000 feet, has handsome purple flowers. The Common Milkwort P. vulgaris L., with flowers of blue, rose, pur- ple, or white, attains a remarkable size in the mountains, and is well worth more attention in our gardens, for it will grow anywhere and is very pretty. CARYOPHYLLACE^: Annual or perennial herbs, with opposite, entire leaves, and no stipules, except in a few genera which have small, scarious stipules ; the branches usually knotted at each pair of leaves. Flowers frequently in dichotomous cymes or panicles. Sepals 4 or 5, free or united into a tubular calyx. Petals 4 or 5, twisted in the bud, sometimes minute. Stamens free, inserted under the ovary. Styles 2 to 5, linear, stigmatic along their whole length. Capsule i-celled, or divided into cells at the base only, opening at the top into twice as many teeth as there are styles. Ovules numerous. CARYOPHYLLACE^E 95 A large family widely spread over the globe, and very numerous in temperate regions, especially in the northern hemisphere, extending into the Arctic Circle and to the summits of the Alps. The genera into which species are distributed are often very arti- ficial, depending on the number of sepals, petals, stamens, or styles. As these numbers are not strictly constant, even in different flowers of the same species, care must be taken in some of the small-flowered Alsinece to count the parts of several flowers if hesitation be felt as to the genus it should be referred to. DIANTHUS L. Pink. Stiff perennials, or more rarely annuals, with narrow leaves. Calyx tubular-campanulate, 5-toothed, with 2-6 imbricating scales at the base. Petals usually crenate, or jagged. Stamens 10. Styles 2. Capsule stalked within the calyx, opening at the top in 4 teeth or short valves. A large genus, spread over Europe and Asia, with a few in S. Africa. Dianthus prolifer L. (Tunica prolifera Scop.). A stiff, erect, glabrous, annual species, simple or with -a few erect branches, 6-12 inches high. Leaves few, narrow, erect, and usually pointed. Flowers small, pink, in compact, oblong terminal heads, the calyx concealed by broad, dry, shining, imbricated scales, from the top of which the small, spreading petals appear. Dry places, roadsides, and hilly pastures, from the plains to the sub-alpine region, as, e.g. in the Gorge de Trient at about 3500 feet. May to September. Distribution. — Almost all Europe; Western Asia, N. Africa. British. A hairy, glandular variety, with longer sheath to the leaves and pedicelled calyx, is called D. velutinus Guss. Dianthus saxifragus L. (Tunica saxifraga Scop.). Stem slender, glabrous, 6-8 inches high, with spreading branches. Leaves linear-acute. Corolla pale rose, veined, small, solitary. Calyx bell-shaped. Capsule ovoid. Arid places from the plains up to about 5500 feet in the Alps, as e.g. near Evolene in 1911. June to August. Distribution. — From the Pyrenees and France to Eastern Europe ; Western Asia as far as Persia. It has recently appeared in Pem- brokeshire as an escape from cultivation. TUNICA is a small genus, not always separated from Dianthus, and differing from it in the calyx being pentagonous and the corolla having no corona. 96 SUB-ALPINE PLANTS Dianthus superbus L. (Plate V.) Stem 18 inches high, rounded, branched above. Leaves linear- lanceolate, soft, but rough at edges, the inferior sub-obtuse, the superior acute. Scales oval, mucronate, J or J length of calyx- tube, purple-red. Petals large, slit and fringed, pink or lilac, with reddish hairs and green spots at the base, rarely white, scented. Woods and damp meadows from the plains up to 6500 feet. June to September. Distribution. — Central and Southern Europe ; Western Asia, Japan. D. speciosus Reichb. is a rare Alpine variety, found in meadows in Southern Switzerland and Tyrol from 5000-7500 feet. D. superbus does not live very long, and is generally treated as a biennial. It requires deep, peaty soil or a mixture of sand and leaf- mould. Dianthus monspessulanus L. This belongs to the same group as superbus, and may be treated in a similar way, though it grows in drier places. The variety alpicola Koch (D. alpestris Sternb. and Hoppe) has i-flowered stems. It is found locally in meadows in Southern Tyrol and Carinthia, at from 1600-2400 metres. D. monspessulanus is a native of Southern Europe. Dianthus Carthusianorum L. (Plate VIII.) Stem about a foot high or higher, simple. Leaves linear-acute ; the stem-leaves with a long sheath. Flowers a deep red, sub- sessile, 2-8 in a dense panicle, surrounded with coriaceous bracts. Scales of calyx scarious, the point reaching the centre of the calyx-tube. Calyx dark purple. Petals obovate, hairy at the throat, toothed ; capsule cylindrical. Arid, stony, and bushy places in the Alps and plains, up to 7000 or 8000 feet in the Alps. June to September. Distribution. — Central and Southern Europe, but rare in the Mediterranean region. A very variable plant with several named varieties, such as atro- rubens, vaginatus, etc. Dianthus Seguieri Vill. Glabrous ; forming tufts of leaves, Stem 12-18 inches high, branching, angular. Leaves linear, flat. Flowers pink, with a purple circle round the centre, in heads of 2-4. Scales long, striated, with erect spreading point, equalling the tube of the calyx.

Leaves soft, the lower ones short and broadly linear, obtuse, with 3-5 nerves ; the stem- leaves longer and pointed. Scales 4, erect, the lower two herbaceous, oval, the point reaching half the length of the calyx. Calyx rather short, 13-16 mm., narrow, striated throughout its length, teeth lanceolate acuminate. Petals glabrous, entire or toothed. Flowers pink or whitish, 1-3 at the top of the stem, longly petioled. Capsule cylindric, extending slightly beyond the calyx. Rocks and dry pastures in the Southern Alps ; rare. June to August. Distribution. — Maritime Alps, Liguria, Piedmont ; Hautes-Alpes and Basses- Alpes. Dianthus sylvestris Wulf. (Plate VIII.) Considered by some a sub-species of D. Caryophyllus L., which is not Alpine, but grows on rocks and walls in Southern Europe, and in Algeria and Morocco. D. sylvestris is a dwarf er plant, more tufted, with 2 small scales to the calyx, and a slight scent. The flowers are bright pink and rather large, and usually in panicles of 1-3 on longish peduncles. The leaves are narrow, linear, acute, pale green or glaucous. A polymorphic plant. Steep hillsides and rocks in the mountains, and sometimes in open woods ; common. It attains 7500 feet, and descends to the plains. June to August. Distribution. — Carpathians, Eastern, Central, and Western Alps ; Jura, Corsica ; Pyrenees ; Central and Southern Europe. It should have an open, sunny position in dry, stony loam, or in rock crevices with plenty of soil. Dianthus glaucus Huds. (D. ccesius L.). Cheddar Pink. A very glaucous plant, forming a short, densely tufted, almost woody stock. Lower leaves crowded, stiff, narrow-linear, but obtuse, about an inch long. Flower-stems 5-10 inches high, simple, i-flowered, or rarely forked, with a few pointed leaves. Flowers rather large, fragrant. Calyx thick, with short teeth, the 4 outer scales broad, shortly pointed, not half-length of calyx. Petals broad, irregularly crenate or toothed. Dry, rocky places, especially on limestone, very local. June, July. Distribution. — Jura, Alps of Savoy and Dauphine*,, Swiss plains, but not in the Alps ; Central Europe. Cheddar Cliffs in England. It grows very well on garden walls. 98 SUB-ALPINE PLANTS Dianthus subacaulis Vill. This small species is well-suited to the rockery, and especially on limestone, like the Cheddar Pink, but it does not seem known in this country. The root is woody, and it sends up tufts of short, rough, linear leaves ; stem angular, simple, from 2-6 inches high. Flowers rose, rather small, solitary. Scales of the calyx broad, short (J to J the length of the calyx), and with short point. Calyx short, striated above, with ovate teeth. Petals entire or crenate. Capsule conical. A variable species. Rocks and rocky pastures, especially on limestone. May to August. Distribution. — Alps of Dauphine and Provence, Cevennes, Eastern Pyrenees ; Spain. j g GYPSOPHILA L. Calyx short, campanulate, pentagonal, without scales at the base. Petals 5, gradually narrowed to the base, without a corona. Styles 2. Stamens 10. Capsule with i cell and numerous seeds. About 55 species inhabiting Europe and Asia. Gypsophila repens L. (Plate XV.) Root tapering, branched. Stem 3-6 inches high, erect or ascend- ing, simple or branched above, glabrous like the leaves. Leaves linear-lanceolate or linear, entire, acute, bluish green, moderately thick. Flowers in loose paniculate cymes. Petals 2-3 lines long, white or pale rose-coloured, more or less emarginate. Calyx bell- shaped, 5-cleft ; teeth lanceolate, membranous at the margin, i-nerved, straight, obtuse, with a short mucro. Capsule sub- globular, obtuse, with a very short carpophore. Dry, rocky, and gravelly places in the calcareous Alps and sub-Alps,1 3000-8000 feet. July, August. Distribution. — Eastern, Central, and Western Alps, from Savoy to Roumania and the Carpathians ; Central Pyrenees, Jura, Poland, Germany. Very easily grown in dry, sunny places, and increased by layers, or from seed. It quickly forms mats of dense foliage and flowering spikes, and hence is very suitable for covering ugly rocks, etc. SAPONARIA Calyx tubular, 5-toothed, without scales at the base. Petals with a corona. Disc small. Styles 2. Ovary 2-celled at the base. Capsule 4-valved. This genus, artificially distinguished by the number of styles, as Bentham says, comprises several European and West Asiatic species. 1 On granite its place is taken by Silene rupestris. CARYOPHYLLACE^E 99 Saponaria ocymoides L. (Plate XX.) Stem trailing. Plant hairy, glandular at the top. Leaves broadly lanceolate or oblong, ciliated, with I nerve. Flowers bright rose, sometimes paler, and rarely white, shortly petioled, in panicles. Calyx cylindric, hairy, glandular, with 15—20 nerves and obtuse teeth, often very red. Capsule oval, 4 times the length of the glabrous carpophore. Stony places and limestone rocks in full sun. May to July. In the Alps it extends up to 7800 feet, but it is by no means a purely Alpine plant, being, e.g. found over the greater portion of hilly France. Distribution. — Central and Southern Europe from the Iberian peninsula to Bavaria and Carinthia ; Corsica, Sardinia. Of very easy culture in sunny positions in deep, loamy soil. Being such a good trailer it is best to plant it so that it will fall over or decorate a rock or bank. It prefers dry soils, and is often killed in wet English winters. Saponaria officinalis L. Common Soapwort. This tall and rather handsome species, with large pink flowers, is sometimes seen by streams in the foot-hills of Switzerland and France. Saponaria Vaccaria L. is an annual found in waste places and in crops. In 191 1 it was growing in a crop of flax above Argentiere, near Chamonix, at a height of 4500 feet. LYCHNIS L. Calyx tubular or inflated, with 5 teeth. Petals 5, with erect claws and a spreading lamina, entire or 2-cleft. Stamens 10. Styles 5, or very rarely 4. Capsule i-celled, or divided at the base into 5 cells, and opening in 5 or 10 teeth or short valves at the top. About 40 species, widely spread over the northern hemisphere without the tropics. Lychnis alpina L. In Alpine Plants of Europe, p. 80, this plant, now usually called Viscaria alpina Don, was erroneously stated to be unrecorded from Switzerland. As a matter of fact it is occasionally found in Orisons (Engadine, Poschiavo, etc.), the Bernese Oberland (Gemmi), and the Valais, as at Zermatt and above Zinal (at 8500 feet in August, 1911). It does not appear to descend to the sub-alpine region of Central Europe, but we have seen it in the Eastern Pyrenees in abundance in some of the more open pine forests at about 5500 feet. It extends upwards in that district to 7000 feet. Lychnis viscaria L. Stems 6 inches to a foot high, glabrous, very viscid in the upper part. Leaves long and narrow, resembling those of the last species. loo SUB-ALPINE PLANTS Flowers red, in close, sessile, or shortly stalked, opposite clusters, forming an oblong panicle or head. Calyx tubular, with 10 veins and 5 short teeth. Petals slightly notched. Rocks and hilly pastures. May to July. Distribution. — Central and Northern Europe to Norway ; Siberia ; Caucasus ; a few places in N. Wales and Scotland. Lychnis Flos Jovis Desr. Plant covered with whitish, silky tomentum. Stems 10-18 inches high, erect, simple. Leaves oblong-lanceolate, acuminate, the upper ones narrower. Flowers deep pink, crowded. Petals deeply divided. Calyx coriaceous, with 10 prominent nerves and broadly acute teeth. Capsule oblong-acute, with five teeth, much shorter than the carpophore. Sub-alpine pastures and broken ground. June to August. Distribution. — Western and Southern Alps, Southern Switzerland, Italy, Tyrol. Lychnis Coronaria L. A taller plant, covered with dense white silky tomentum. Leaves oblong-lanceolate, acute. Flower solitary, axillary, and terminal, large and handsome, reddish purple, or rarely white, longly petioled in a loose, dichotomous spray. Calyx with 10 unequal nerves and linear teeth, much shorter than the corolla. Petals entire or slightly crenate. Capsule oblong-acute, without carpophore, 5-toothed. Wooded hills and rocky, bushy places in the plains and sub- Alps. Reaches a considerable height in Val Tournanche and the Saas Valley. May to July. Distribution. — Southern Europe from Portugal to the Caucasus ; probably only in Valais in Switzerland, except where it has escaped from gardens, it being a favourite plant in cottage gardens, as in England. SILENE L. Calyx, corolla, and stamens as in Lychnis. Styles 3. Capsules opening at the top in 6 teeth or short valves. A very large genus, of about 256 species, widely spread over Europe, Central and Northern Asia and N. America, with a few species in S. Africa. Silene acaulis L. Usually stemless or with stems J to I inch high. Root woody, branched, with many aerial shoots, covered with the withered leaves, and bearing a rosette of fresh leaves forming dense, cushion-like tufts. Sometimes hemispherical masses a foot across are seen covering rocks or grassy ground in Alpine pastures. Leaves radical, linear, acute or acuminate, entire, shortly ciliated, other- wise glabrous. Flowers dioecious or hermaphrodite, solitary at the extremity of the shoots. Calyx cylindrical, or bell-shaped, with CARYOPHYLLACE^: 101 10 nerves ; teeth ovate, obtuse. Petals obovate, lanceolate, rose- coloured, slightly emarginate. Rocks and pastures in the Alps ; common, 5000-11,000 feet. May to July. Distribution. — Carpathians, Eastern, Central, and Western Alps ; Pyrenees, British Isles, Arctic Europe, Asia and America ; Iceland, Spitzbergen. Rocky Mountains of Canada. There are two varieties which grow in the Alpine zone only : Var. exscapa DC., a stemless, small form with lighter pink flowers, and Var. elongata DC., a rare form with longer stems than in the type, larger flowers, and a looser habit. Though a shy bloomer in this country, Silene acaulis is a very useful rockery plant. It should have plenty of sun, and a poor, gritty soil, or it will make too much soft green growth, which gets cut off in winter. It may be wedged between stones in crevices of rock. Silene inflata Smith (S. Cucubalus Wibel.). Bladder Campion. (Plate VIII.) Loosely branched at the base, with ascending or erect stems a foot or more long, of a glaucous green, and usually glabrous. Leaves ovate, oblong, or rarely nearly linear, and usually pointed. Flowers few, white, or pinkish in the mountains, often slightly drooping, in loose terminal panicles. Calyx becoming at length globular, inflated, and much veined. Petals deeply 2-cleft. A variable species, especially in the mountains, where it sometimes assumes a pinkish tinge, as in the plate. Fields, waste places, and Alpine pastures ; very common. April to August. Distribution. — All Europe, Western and Central Asia, Northern Africa, N. America. British. In Mr. F. N. Williams' European Varieties of Silene inflata1 he describes the var. alpina, Mert. and Koch, and mentions that it was gathered by the present writer on the Col du Galibier in Dau- phiny at 2440 m., " the greatest altitude hitherto recorded for the plant." It was however, recorded at 3000 m. on the Corner Grat,2 by Heer. Silene Elizabethce Jan. Rootstock densely covered with leaves ; stem simple, ascending, 3-6 inches high, finely glandular, hairy above. Root-leaves lan- ceolate, acute, narrowed at the base ; stem-leaves ovate-lanceolate.

Distribution. — Europe, Russian Asia, N. America, Andes of S. America, Morocco. There are several Alpine varieties, the commonest of which is strictum Haenke (alpicolum Fenzl.), which is smaller, very thick-set, and with narrower leaves and smaller flowers. We have gathered it at 9000 feet on the Aiguille du Gole*on in Dauphine and on the Col de la Leisse in Savoy at the same elevation. Cerastium grandiflorum W. and K.

Flowers large, handsome, sometimes covering the whole plant with white. Teeth of capsule revolute. Rocky pastures in Upper Styria and elsewhere in the Eastern Alps ; rare. July, August. Grows easily and freely from cuttings or by division, but is CARYOPHYLLACE^E 105 somewhat too rampant to associate with the smallest and choicest Alpines. The majority of the Cerastia are either lowland plants or distinctly high Alpine ; though occasionally in the sub- Alps we find C. pumilum and semidecandrum from the plains, and C. trigynum and C. alpinum descending from the higher mountains. ALSINE Wahl. Petals 5, or rarely 4, entire or slightly notched. Stamens 5, 8, or 10, all attached to the disc. Styles usually 3. Capsule 3-valved. Leaves mostly linear or linear-lanceolate.

Sometimes considered a sub-species of A. ciliata, from which it differs by the absence of sterile shoots, and by the longer stems, which are many-flowered. Leaves oblong-lanceolate, ciliate at the base. Sepals oblong-lanceolate, acute, 3-nerved, the lateral being sometimes hardly visible. It grows by the Lac de Joux in Switzerland, in Sweden, and about Ingleborough and Ribbleshead in Yorkshire, where it is spreading fast. It flowers in June. This rare plant was first discovered in England in 1889. Mr. Wm. Whit well l gave a detailed account in The Naturalist of its occurrence in several places, and Mr. Arthur Bennett has written on it in the Journal of Botany, November, 1892. Arenaria montana L.

Capsule separating into 5 one-seeded carpels, which curl upwards, and with a long elastic awn, detached from the beak. A genus of about 150 species spread over the northern hemisphere, with a few- species in the southern (extra tropical). Geranium macrorrhizum L. Rootstock oblique or horizontal, thick, and covered with the tufts of withered leaves. Stem about a foot high, erect, branching dichotomously. Leaves shiny, palmately 7-fid, cut and serrated.

Sempervivums are most attractive plants for walls and rockeries, and they are readily increased by division of the offshoots. They are all of very easy culture in any light soil in hot aspects, and may be grown on almost any kind of rock. They can be attached to rock by means of fairly moist clay and the plant dibbled in, and they will soon grow and make a good clump.

It is quite impossible in a book of this character to describe more than a very few of the most important of the many Hieracia found in the lower Alps. Nor can there be much advantage in giving a bare list of the innumerable species, many of them difficult to distinguish, which frequent the Alpine and sub-alpine regions. An up-to-date arrangement of those found in Switzerland alone can be found in the Flore de la Suisse, by Schinz and Keller, while Gremli's Swiss Flora (at present out of print in the English edition) also gives a good account of them.

Abundant, but local, in stony Alpine and sub-Alpine places, on limestone, but not making such a feature in the landscape of the Eastern Alps as the other species, the flowers being paler, and the leaves appearing only after the flowers. May to July. Distribution. — Carpathians, Eastern Alps from Tyrol to Carniola, 4000-5000 feet. A partially shaded place suits it best. To succeed in the sun with it, the plant must be well established before planting out, or it must be shaded from the sun by artificial means ; then it will bloom much more freely than in a shady place. Hard peat and sand should be pressed firmly against the roots, and it should be top-dressed twice a year with the same compost. (W. A. Clark.) ANDROMEDA L. Andromeda polifolia L. Marsh Andromeda.

About 400 species inhabiting Europe, the Mediterranean region, and S. Africa, but with only one truly native species in Switzerland, viz. Erica carnea ; for though E. vagans (the Cornish Heath) grows in the Canton de Geneve in a wood near Juvigny, and at the foot of the Voirons above Lake Leman, it is doubtfully indigenous, though it is native on French territory to the west. Erica carnea L. A shrubby, somewhat prostrate plant, with branches 3 inches to I foot long, erect or ascending, glabrous like the whole plant. Leaves 4 or more in a whorl, deciduous, acicular.

Distribution. — Central and Northern (but, excepting Iceland, not Arctic) Europe, and most of the mountain ranges in the south ; Spain, Italy. British. Gentiana baltica. Murbeck. This little-understood plant is probably a sub-species of the last. Dr. C. E.

BORAGINACE^E 219 CONVOLVULACE^E Twining or prostrate herbs, with alternate leaves, or leafless and parasitical (Cuscuta). Calyx of 4 or 5 sepals often very unequal. Corolla usually campanulate, with 4 or 5 lobes or nearly entire. Stamens 4 or 5, attached near the base of the corolla. Partitions of the capsule very thin. The family is not represented in Alpine regions properly so-called, but in the lower mountains of Europe Cuscuta or Dodder is fre- quently seen. CUSCUTA L. Dodder. Cuscuta Epithymum Murray. (Plate X.) Lesser Dodder. An annual parasitical, leafless plant, with twining, thread-like reddish stems, which attach themselves to Thyme, Heath, Gorse, and other shrubby plants by means of minute suckers. The heads of flowers are small, globular, and compact, the flowers themselves being very small, white or pale pink, and the calyx still smaller. Corolla-lobes pointed, spreading, and about as long as the tube. Capsule globular, with 4 seeds in 2 cells. Parasitical upon various plants in sunny places in the plains and Alps to at least 6000 feet. July to October. Distribution. — In Europe from Denmark southward, N. Africa, W. Asia. British. Dodder was observed by the author during the hot summer of 1911 in unusual abundance in the Pennine Alps and upon a variety of plants, such as Euphorbia Cyparissias, Carduus defloratus, and Teucrium montanum. He also found it actually parasitical upon two fronds of Polypodium Robertianum, which is perhaps the first record of any kind of Cuscuta upon a fern ;x though, according to Prillieux, Rye-grass has been attacked by C. Epithymum. It is also occasionally found on Lotus corniculatus, Lavender, and other Labiates, Hypericum and Achillea millefolium. When Dodder grows on Clover, or Lucerne, which it often does in the sub-Alps, as in England, the name C. Trifolii Bab. is given to the variety. It differs from the type in its shorter distant scales. Several other species of Cuscuta are occasionally found in the lower mountains of Southern Europe, but they are difficult to determine, and it is hardly within the scope of this book to attempt to describe them here.

SCROPHULARIACE^E 235 Schinz and Keller point out that the genera Melampyrum, Rhinanthus, Euphrasia, and certain Gentians present a seasonable differentiation (un dimorphisme saisonnier) : ' Une espece donnee peut se redoubler par adaptation directe a la station en une race printaniere ou estivale peu rameuse, fleurissant et fructifiant de bonne heure et une race automnale tres rameuse, fleurissant et fructifiant plus tard.' * For information on these interesting points and for a full de- scriptive account of the species and sub-species of this difficult genus found in Switzerland the reader is referred to the Flore de la Suisse, by Schinz and Vilczek. Rhinanthus sub-alpinus Schinz and Thellung. (Plate XXVIII.) Plant 6-12 inches high. Stem streaked with black, almost glabrous. Leaves broadly lanceolate, crenate-dentate, sub-acute.

There are about 150 species inhabiting the mountainous parts of Europe, Asia, Africa, and America. Many are acrid, and consequently harmful to the pastures. Nearly all are Alpine or sub-alpine, and the great majority in the Alps grow from about 4500-6000 feet, and having been fully treated in the author's Alpine Plants of Europe, he does not propose to repeat many of those descriptions here, but to give a brief summary of them and to add a few species which grow at lower altitudes. This summary is based on that of the late A. W. Bennett.2 A. — Flowers yellow. Upper lip of corolla drawn out to a long narrow beak : P. elongata Kerner.

Distribution. — Europe, especially Central ; Western and Northern Asia. British. Orchids are generally considered difficult to cultivate, and many have a reputation for not flowering when transplanted. But if they are never moved when in flower or making growth, but in the early autumn, they are much more likely to succeed. A moist loam and peat suits most, but others require lime mixed with the loam instead of peat. All require a deep soil. It is much to be hoped, however, that collectors will leave alone not only many of the British species, but all the rarer ones which grow in the Alps. Those which are parasitic are particularly difficult to cultivate, and are best avoided.

Characters and habit of Scirpus, except that the bristles finally protrude far beyond the glumes, forming white, silky or cottony tufts, and hence the English name of Cotton-grass. The style is usually 3-cleft. Only about a dozen species are known, restricted to the temperate and cold regions of the northern hemisphere. Several are frequent at considerable elevations in the Alps and other mountains. Eriophorum alpinum L. Alpine Cotton-grass.

CYPERACE^i 295 A very large genus of about 800 species, spread widely over Europe, Northern Asia, and North America, extending into the mountain ranges of the tropics, and reappearing in the temperate regions of the southern hemisphere. Many species, and most of the large ones, grow in wet places. In order to correctly determine many kinds, it is necessary to have specimens with more or less ripe fruit. In the European Alps about 20 species reach the upper limit of Alpine pastures, or about 8000 feet ; and at least another score are found between 5000 and 7000 feet. At Mont Cenis alone the author collected 33 species of Carex from above 6000 feet in July and August, 1907. l It is probable that in the whole of Switzerland so large a number could not be found at that height ; though Switzer- land yields about 88 species and sub-species, or a few more than are found in the British Isles. In the present work it is only possible to give brief descriptions of some of the most characteristic species commonly found in sub- alpine regions. Carex pulicaris L. Flea Sedge. A small tufted species, 4-8 inches high, with narrow leaves shorter than the stem. Spikelet terminal and solitary, male in the upper half, the lower flowers being female. Stigmas 2.

Distribution. — Most of Europe from Scandinavia to the Caucasus. British. Carex microglochin Wahl. A somewhat similar species in habit and size. Spikelet 10-12 flowered. Fruit with a long, green bristle at the base, ovate- lanceolate, 5 mm. long, dark brown. Leaves setaceous, channelled. Alpine and sub-alpine marshes and bogs ; rare. June. Distribution. — Switzerland (Orisons, Valais, etc.), Mt. Cenis, Savoy, Central and Northern Europe and Asia ; Greenland. Carex pauciflora Lightfoot. A small slender species, with long creeping runners and slightly branched stem, decumbent at the base, occasionally tufted. Leaves narrow, the upper ones sheathing the stem to the middle. Spikelet solitary, pale brown, with a few flowers, the male being uppermost. Stigmas 3. Fruit narrow and pointed, spreading or reflexed when ripe, nearly as long as the spikelet. 1 H. S.

GRAMINE.E. (The Grass family.) Herbs, with usually hollow stems, except at the nodes, and narrow, parallel- veined, entire, alternate leaves, sheathing at the base ; but the sheaths usually split open on the side opposite the blade, and end in a small appendage called a ligule. Flowers in spikelets, arranged in spikes, racemes, or panicles. Each spikelet generally consists of 3 or more chaff-like scales or bracts called glumes, arranged alternately, with their concave face towards the axis. The 2 lowest glumes are usually empty, but the flowering glumes enclose a smaller scale called a palea, which usually has 2 longitudinal veins or ribs. The flower is within, the palea or between it and the flowering glume. The true flower usually consists of 2 almost microscopical scales called lodicules and of 3 stamens (rarely 6) and of an ovary with one cell and one ovule, crowned by two more or less feathery styles. However, the flower is generally considered to include the flowering glume and the palea. The fruit is a i-seeded grain, consisting of the real seed and pericarp ; and is either free or enclosed. The embryo or germ is small, at the base of a mass of mealy albumen. Several other points will arise in any extended and exact study of this large and somewhat difficult family — the Grasses are dis- tinctly more difficult than the Sedges, and they require careful dissection — but the outline indicated above is sufficient for the purpose of the average botanical student. GraminecB is one of the largest families, its representatives being spread throughout the globe. At least 4000 species are known to Science. Grasses are found from the burning plains of the Equator towards the North and South Pole as far as any Flowering plants have been seen, and from the coast (several actually growing in and matting together the sands of the sea-shore) to the snow-capped summits of some of the highest mountains. In temperate regions they form the chief green carpeting of the soil, while in tropical climates some species of Bamboo attain the height of tall trees. Lastly, but of most importance, in every country inhabited by man grasses are cultivated as cereals for food. Switzerland in bygone ages knew something of the value of these cereals, for several varieties of Barley were found in Swiss lake dwellings in deposits of the Stone Period. About 70 species of true Grasses are found in the High Alps of Central Europe, of which number many extend above 8000 feet. GRAMINE^ 301 More than 100 others grow in the lower mountains and adjacent plains, but it is almost impossible to say what proportion of the whole are to be found in the sub- Alps, and the number of grasses which are purely sub-alpine is extremely small. The following genera comprise most of the high Alpine species and some of the sub-alpine, viz. Phleum, Agrostis, Deschampsia, Stipa, Trisetum, Avena, Sesleria, Poa, and Festuca. In addition there are many sub-alpine grasses which belong to the following genera, viz. Alopecurus, Air a, Anthoxanthum, Milium, Sieglingia (Triodia), Koeleria, Melica, Cynosurus, Nardus. In the whole of Switzerland there are, on the authority of Schinz and Keller, 169 species of Grammes in addition to a few sub-species.1 In the British Isles there are not more than about 135 species, excluding all varieties, notwithstanding the very long coast- line and great variety of geological formation. We regret that from want of space it is impossible to give de- scriptions of the grasses, for any adequate account of so numerous a family would make the volume too large. 1 Flore de la Sut'sse, by Schinz and Keller. Ed. fran9aise par Wilczek et Schinz (1909). CLASS III. GYMNOSPERM^E CONIFERS Trees or shrubs with resinous juice, and usually rigid, subulate leaves, often in fascicles and entire in the European genera. Flowers monoecious or dioecious. Male flowers in catkins, of i or more anthers, female flowers solitary or in cones of I or more, sessile, naked, ovules, placed on a bract or open carpellary leaf. Fruit a cone or berry. An extensive family spread over the whole globe. PlNUS L. Trees with linear or subulate, fascicled leaves. Male catkins in spikes of many 2-celled anthers. Cone ripening the second year. Ovules 2, inverted and adnate to the carpellary leaf. Pinus montana Miller. Leaves narrowly linear, flat or channelled on the upper side, convex below, mucronate, scarcely acicular, in pairs within a sheath, persistent. Male catkins long, congregated in whorled spikes at the base of this year's shoots. Female catkins oval or longer, solitary, or 2-6 together, in the first year at the apex of this year's shoot, in the second year lateral from the growth of a new shoot, erect during and after flowering, spreading obliquely or horizontally when ripe, sessile. Scales nearly as long as the carpellary leaves at the time of flowering, and more or less concealing them. Cones ovate or ovate-conical before opening. Scales of cone variously spathulate, compressed, 3-sided ; shield within an irregularly 4-cornered or nearly 3-cornered beak. A tree, with shorter trunk and prostrate or ascending branches in the form known as P. Mughus, often covering large tracts in rocky Alpine slopes ; 4400-7500 feet. May, June. The short form is more especially found on limestone ; the taller tree grows in the Alps and sub- Alps, and in Swiss peat-mosses descends to 2000 feet above sea-level. Distribution. — Carpathians ; Eastern, Central, and Western Alps ; Jura, Vosges, Pyrenees, Caucasus ; Central and Eastern Europe. Pinus uncinata Ramd. is a variety of the above with the bosses 302 CONIFERS 303 of the scales on the lower side of the cone larger than those which are turned towards the trunk, recurved in the form of a hook. It becomes a tall tree in the Valais and in Vaud, but is little more than a shrub in the Jura. Pinus sylvestris L. Scots Pine. Cones very shortly stalked, recurved when young, symmetrical, conical. Scales rhomboid, with flat boss and a transverse keel and deciduous point. Leaves in pairs, stiffly subulate, about 2 inches long, glaucous inside. The heart-wood is reddish. Seeds winged, small. This well-known Pine reaches about 7300 feet in the Swiss (Valais) Alps, where it is rare, and possibly rather higher in some of the Western Alps of France and Italy. May. Distribution. — Alps, Vosges, Cevennes, Pyrenees, Corbieres, Norway, Northern and Central Europe, mountains of Southern Europe, Caucasus, Russian Asia,1 Scotch Highlands. Usually planted elsewhere.

In Switzerland in the Pennine Chain from the Dranse to the Simplon, the Bernese Ober- land, and Engadine. It is often associated with the Larch. There are proofs of more elevated ancient limits in many localities. A beautiful photograph of " A typical Alp or mountain pasture, with the Stone Pine in the foreground (6300 feet) " appears in Dr. Arber's Plant Life in Alpine Switzerland, p. 24. Pinus Strobus L. Weymouth Pine. A tree attaining 80 feet in height. Leaves in bundles of 5, 2-4 inches long, slender, trigonous, green and glossy on one side, glaucous on the 2 other sides. Cone shortly peduncled, up to 6 inches long, cylindrical and tapering, pendent, chocolate-brown in colour. Scales rather thin, smooth, striated. 1 In Siberia the Scots Pine reaches lat. 62^° (Seebohm), and in Norway it reaches the North Cape, 300 miles within the Arctic Circle. 304 SUB- ALPINE PLANTS Completely naturalised and often cultivated in Switzerland and France, both in masses and singly in the forests. May. Originally from N. America. Pinus Laricio L. This southern species is cultivated in plantations, and solitary specimens are occasionally seen in forests, but it is not supposed to be native in Switzerland. The leaves are long and glaucous, the cones ovoid-conical, sub-sessile, the boss of the scales pale yellow. Heart-wood blackish grey. ABIES Miller. Fir. Characters the same as those of Pinus, but the leaves are solitary and evergreen. Abies alba Miller (A. pectinata DC.). Silver Fir. Leaves pectinate, 2-5 cms. long, with 2 white lines beneath, disposed all round the fruiting twigs at the top. Cone-cylindrical, reddish violet first, then green, erect, shorter than in A. excelsa (8-10 cms.), with prominent bracts. Scales dentate, shortly petioled, and falling with the seeds. Heart-wood light grey. According to Schinz and Wilczek it reaches a height of 1800 metres in Switzerland, and forms great belts of forest from about 1000-1600 metres, and to 1300 metres in the Jura. According to my own observation in the Eastern Pyrenees this tree forms (with P. austriaca and P, picea) the chief forests, and in certain districts the forest-belt lies between about 5500 and 6700 feet. May. Distribution. — Eastern, Central, and Western Alps ; Vosges, Jura, Pyrenees, Corsica ; Central and Southern Europe, Caucasus, Asia Minor. PICEA Dietrich. Leaves (or needles) compressed, 4-angled. Cone pendent, falling in one piece (in A bies the scales only fall) , the scales persistent on the rachis. Picea excelsa Link (Abies excelsa Poir.). Spruce Fir. Leaves mucronate, somewhat 4-edged, green, disposed equally all round the twigs. Cone cylindrical (10-15 cms.), pendulous, without bracts. Scales dentate, sessile, and persistent. Heart- wood brown. In Switzerland it reaches from the plains to the upper limit of trees (1650-1980 metres), except in Tessin, the Grisons and the Valais, where the Larch and the Arolla Pine (P. Cembra) are the highest trees (Schinz). Distribution. — Eastern, Central, and Western Alps ; Jura, Vosges, Central and Northern Europe, Siberia. Very often planted. CONIFERS 305 LARIX Miller. Larch. Leaves fascicled, deciduous. Seeds winged. Larix euvopcea DC. (L. decidua Miller). A tree sometimes attaining a height of 160 feet. Leaves, or needles, in fascicles of 20-30, slightly channelled, deciduous, bright green, turning yellow-ochre in autumn. Cone ovoid, erect, reddish purple when young, grey-brown when mature, 3-4 cm. long, with persistent scales. This most useful timber tree reaches 2400 m. (7870 feet) in Switzerland and the Western Alps — the extreme limit of trees, and is almost totally absent from the Jura and sub- Alps. Very fine specimens can be seen just above Saas Fee in Switzerland. Distribution. — Eastern, Central, and Western Alps. Central Europe, Siberia. Elsewhere planted. On the Yen-e-say River Henry Seebohm tells us the Larch and Birch extend further than any other trees, viz. to lat. 69!°, and the Spruce comes next.1 In 1910 a book on Tree Limits in the Eastern Alps was published by Dr. Richard Marek2 in which a table was given which shows some of Kerner's results compared with Marek's, which were largely based on already published maps and literature. The table is as follows : yy f • . Upper limit of trees, Limit of forest, Difference Kerner (metres). Marek (metres). (metres).

TAXUS L. Yew. Trees or shrubs with short, linear, evergreen leaves. Flowers mostly dioecious. Catkin very small, with imbricated scales at the base ; the males ending in a cluster of stamens ; the females con- sisting in a single erect ovule with a small cup-shaped disk round its base. Fruit a hard seed, partly embedded in a pulpy, berry-like cup. A small genus, extending round the northern hemisphere. Taxus baccata L. Common Yew. A dark, evergreen, much-branched tree, with thick trunk and hard wood, attaining a great age. Leaves not an inch long, inserted 1 Henry Seebohm, Siberia in Asia. 2 Marek, Waldgrenzstudien in den Oesterreichischen Alpen, X 306 SUB-ALPINE PLANTS all round the branches, but spreading in one plane in two opposite rows, convex and shining on the upper side. Catkins very small, in the axils of the leaves. Fruits small, but conspicuous by their bright, pinkish red, juicy cups. Rocks and limestone cliffs and thickets in the plains and moun- tain region. April, May. Fruit in August and September. In Switzerland spread over all the geological subsoils in coniferous and ordinary forests ; in the hills and sub-Alps up to 1400 m. (Schinz) in the Jura and valley of the Rhone and in Tessin. Distribution. — Central Europe, mountains of Southern Europe, extending northward to Scandinavia and eastward to the Caucasus and mountains of Central and Northern Asia ; Algeria. Probably native in England on chalk and limestone. In Kingley Vale, near Chichester, there is perhaps one of the finest examples in Europe of a nearly pure Yew- wood.1 JUNIPERUS L. Juniper. Shrubs with glaucous, subulate, stiff and pointed or scale-like leaves. Cone berry-like, small, composed of fleshy scales, blue when ripe (in the second year). Ovules i or 2 under each scale, erect. About 30 species spread over the northern hemisphere. Juniperus communis L. A much-branched, evergreen shrub, often procumbent, but usually ascending, 2-4 feet high. Leaves in whorls of 3, linear, acicular, 10-15 mm. long, ending in a prickly point, green above, glaucous beneath. Catkins very minute. Berries globular, purplish blue, as large as Bilberries when ripe (the second year). Dry hillsides and mountain slopes up to the Alpine region. April, May. Distribution. — Europe, Western and Northern Asia, N. Africa and N. America. British. It passes insensibly into the variety montana Aiton (/. nana Willd.), which is always procumbent, with shorter imbricate leaves (4-8 mm.) and larger berries. The variety is widely spread in the Alps from 5500-8200 feet, and very occasionally as high as 11,500 feet in Switzerland, which gives it the distinction of being the highest woody plant in Europe. Vaccari2 actually records it from 3500 m. (11,700 feet) on Monte Rosa. It flowers in June and July. Distribution. — Alps, Carpathians, Jura, Auvergne, Pyrenees, 1 A. G. Tansley in The New Phytologist, vol. x (1911), p. 288. 2 Prof. Lino Vaccari, La Flora Nivale del Monte Rosa (1911), p. 27. CONIFERS 307 Corsica, Cevennes ; Arctic Europe and Asia, Himalaya, N. America, Algeria, rare in England. In Siberia the Juniper reaches lat. 69° (Henry Seebohm). Juniperus Sabina L. Leaves like small rhomboid imbricated scales in 4 rows, or acicular, broadly subulate and spreading. Cone or ' berry ' on a short recurved stalk, not so dark in colour as the other. Bark of the branches reddish brown. Dry, stony places up to 8200 feet. Flowers in April and May. It is a characteristic shrub of some of the hot Alpine valleys and Pine forests in the south of Switzerland. Distribution. — Eastern, Central, and Western Alps ; Jura, Pyrenees, Caucasus, Siberia, N. America. EPHEDRACE^: or GNETACE^) Leaves opposite, very small. Flowers unisexual, male flowers with a tubular membranous perianth, otherwise resembling Conifers. A very small family of chiefly tropical and Mediterranean pfflts. Ephedra helvetica C. A. Meyer. A small dioecious shrub, with opposite branches and no leaves. Stem 1-2 feet high. Female catkins when ripe appearing like red berries, peduncled ; male catkins sessile. The plant resembles certain species of Equisetum in outward appearance. Rocky hillsides ; local. In Switzerland only in Valais (Sion, Sierre, Fully, etc.). April, May. Distribution. — Valais, Dauphiny, Central Europe. NOTE.— Conifers possess a power of resistance to extreme cold unsurpassed by any form of vegetation except perhaps the micro- scopic plants which live in the oceans of Arctic regions. The Siberian settlement of Werchsjanst, in about 68° N. lat., is perhaps the coldest inhabited place in the world. The maximum winter temperature is never less than 76 degrees of frost, and occasionally there are 100 degrees of frost. Yet this settlement is surrounded by coniferous trees. Dr. Borthwith x recently alluded to Kienitz's investigations into the shapes and types of Scots Pine, of which there are two distinct types. The typical Scotch form is a strong-branched, strong- crowned tree. The other is slender and pyramidal, and occurs generally in the Baltic provinces. 1 In Address to Bot. Soc. of Edinburgh ^ November, 1911. CLASS IV.— VASCULAR CRYPTOGAMS IN Switzerland alone there are about 45 true ferns (excluding Botrychium, Ophioglossum, etc.), or just about the number to be found in the British Isles.
