In the year 1888 there was issued from the Colonial Herbarium> which was then in its infancy, a small pamphlet entitled ‘An Analytica Key to the Natural Orders and Genera of Natal Indigenous Plants ” ; this work which it must be admitted was very defective, was, however, | found useful, but is now quite out of date. In 1894 there was issued from the same Institution a “Preliminary Catalogue of Indigenous Natal Plants” which contained the names of the plants only, with an indication of the altitudes above the sea level at which they had been observed, but without any other information about them; the present work is an attempt to combine the two previous attempts with such additions and corrections as longer experience and fuller information from outside sources has shown to be necessary. ‘he ‘“‘ Preliminary Catalogue” included 131, (by mistake 129) Orders, 828 genera, 2216 species and 391 varieties or unnamed species. Since the publication of that List numerous names have been added, partly by the collection of specimens which included species not previously known to us to be natives of Natal, but chiefly by the continuation of the Flora Capensis, of which work, one complete Volume and six Parts of other volumes have been issued, in all of which are enumerated species not known to us, and some not included in our collection. The present List includes 133 Orders, 907 genera, 3447 species and 83 varieties, or plants not known to us to be specifically named. A number of the names have also been obtained from foreign publications which have come into our possession by exchange or otherwise, and it is thought that the list is now fairly complete, but any additional names which may come to our notice will appear in the Annual Reports of the Director of the Botanic Gardens and Herbarium. The Keys to Orders and genera have been completely revised, and it is hoped that they may be found to be useful, while the Key of the large Order Graminee is abridged from that given in the Flora Capensis by omitting all genera and species which are not known to be indigenous or introduced into Natal. It has been found impracticable at present to write keys to the species; a large number of them are not in our collection, and of many of them we have not even a description, but any specimens sent to us will be examined and the names in most, if not in all cases. will be supplied ; printed directions for preparing and sending specimens will be sent on application, together with printed direction labels which will pass them free by post or rail. In large genera such as Indigofera, Senecio and others it would . have been an advantage to have arranged the species in the Sections to which they belong, but even this, for reasons given above has not been found to be feasible. In using the Keys it must be remembered that 4 they refer to Natal plants only, and not necessarily to any not included in this List, also that they are quite arbitrary, and in many cases have little or no real botanical significance. The Capital letters following the names of the species indicate roughly the altitude at which the plants have been found, in the largest number of cases by ourselves, in others the information has been obtained either from collectors other than ourselves, or from the works in which the plants have been described. but in some cases this information has not been obtainable. It must not be supposed that the plant is confined to the altitude given, but only, that it has been collected in the region indicated ‘The significance of the letters is as ‘under : A, 0 to 1000 feet alt.; B, 1000 to 2000 feet alt.; C, 2000 to 3000 feet alt.; D, 3000 to 4000 feet alt.; E, 4000 to 5500 feet alt.; F, over 5500 feet alt. As the distribution of the Ferns is better known than that of the flowering plants, and collectors and admirers of them are more numerous, the localities are given with more precision, and the keys to the species are also given, these being taken with little alteration from a small pamphlet published by the writer in 1877, and which is now out of . print. | The numbers prefixed to the Orders are the numbers under which they stand in the Genera Plantarum, the numbers wanting in our list, are those of Orders not represented in our flora; they are as under, alphabetically arranged :— Alismacez Columelliacee | Hydrophyllacee Pontederiaceze Aristolochiacee — Coriariev Juglandez Rapataceze Balanophoreze Cupuliferez Lacistemmacee Roxburghiacez P a | Balanopsez Cyclanthaceze Leitneraceze Sabiaceze Batidiz Cyrillee Lemnoacee Salvadoraceze Berberidacewz Cytinaceze Loasez Sarraceniaceze Bromeliaceze Datisceze Mayacew Simaru bez é of: ) Burmanniacee = Diapensaceve Monotropee Stackhousez Calycanthez Dilleniaceze Moringee Stylideze y . ot Calycereze Dipterocarpee Myoporinee Styraceze Canelliaceve Elatinez Myristicez ‘Taccaceve y Caprifoliacee EKleagnaceze Nepenthaceze Tamariscinee Casuarine Empetraceze Orobanchacee ‘Ternstromiaceze Centrolepidee § Epacridez Pandane Tremandre Chaillettiaceve Frankeniacew Penneacez Triuridez Chloenaceze Gnetaceze Phylidracee Turneracez Chloranthacezee Humariaceze Platanacez Vacciniaceze Cistinez Hydrocharideze Polemoniacee — Vochsiaceze The following Orders are in Natal represented by one indigenous species only, so far as known to us at present.

In conclusion I wish to offer my sincere thanks to the author and editors of the Flora Capensis; without the assistance obtained from that work the present attempt could hardly have been made, also to Prof. H. H. W. Pearson, M.A., F.L.S., who so kindly looked over all our specimens of Thymeliacew, and supplied us with the names as far as it was possible to do so at present; to Dr. Harry Bolus, F.L.S., of Capetown who has supplied us with the names of a number of plants which were not in our collection, or known to us as natives of Natal, and with other information which has been of much use to us; and also to Mr. M. S. Evans, C.M.G., M.L.A., who has kindly allowed us the use of the lists received from Kew of the names of the plants of his own collection, and has contributed some of them to the Colonial Herbarium ; to the whole of-these gentlemen I am much indebted for the assistance so freely given.

Some yield excellent timber, others are useful on account of the amount of tannin contained in their bark or fruits The fruits of U'erminalia Chebula are known as ‘“. Myrabolans”’ and used fer tanning, and the galls on the leaves are used for the same purpose. The leaves of several species of the genus Terminalia form the food of the ‘“'Tussa” silkworm. 1’. catuppa is a. handsome tree, and its fruits are eatable. 1’. angustt- folia yields a white, scented gum, which is used as a cosmetic and for 49 burning as incense. The seeds of our Combretum bracteosum when eaten produce violent hiccough, and are known locally as “ Hiccup Nuts.” None of our species are of much economic value. Number of species about 240. (Ex.

Hugenia caryophyllata yields the “Cloves” of commerce, and H. Pimenta, the “Allspice,” and the fruits of several species of Eugenia are eatable. The well- known Guavas belong to this Order, as do the Eucalypti. The seeds of Bertholettva eacelsa are known as “ Brazil Nuts,” and the seeds of Lecythis ollaria as ‘‘Sapucaya Nuts.” Vases, etc., are made of the capsules of this tree, hence the name of “ Monkey Pot”? by which the fruits are known. Melaleuca cajeputi yields “Cajeput Oil,” and is used medicinally. Ouronly useful species is Hugenia cordata, the well- known “ Waterboom,” the timber of which is valuable for building purposes, etc. Number of species about 1800. (Ex. Warerzoom, Guava.)

MELASTOMACEA, A tropical and sub-tropical Order, the greater number of its members being natives of 8. America, with but few in other countries. The berries of some species of the genus Melastoma are eatable, but stain the mouth, hence the name of the Order. None are of much, if any, economic value; but some bear brightly-coloured and very orna- mental flowers, such as Pleroma macrantha, commonly cultivated in gardens.

The “Henna,” which is used by some women in India for dying their nails. and hair is Lawsonia alba. The Lagerstroemias are cultivated for the beauty of their flowers, and are known locally as ‘“ Pride of India,” One of them, L. Flos-Reginex, yields a valuable wood, and the timber of some other species is used in India. None of our species have any economic value. Lythrum and Neszea are herbaceous plants. Hetero- pyxis and Rhynchocalyx are shrubs or small trees, the latter plant being apparently very rare, one plant only, so far, having been observed by botanists.

PASSIFLOREA, A small Order of tropical and subtropical plants, the largest number of which are found in America. The Passifloras are well known both as ornamental plants and also on account of their eatable fruits, commonly known as “ Granadillas,” of which there are several species and varieties; but it may not be so well known that the roots of some at least of the species are considered to be poisonous. Curica papaya isthe common “ Papaw,” too well known in Natal to require further notice here. From its sap ‘‘ Papaine”’ is obtained by evapora- tion, and is used medicinally. One of the American species of Carica is said to be very poisonous. A Number of species about 250. ; a ey (Ex. Passion FLower ; GRANADIDLA.) Flowers bisexual. Calyx 3-parted. Corona double.

An Order of plants remarkable for the large number of culinary vegetables included in it, such as “Celery” (Apiwm qraveolens), “Parsley” (Petroselinum sativum), “Caraway” (Carum carui), “Anise” (Pimpinella Anisum), “Fennel” (Faniculum vulgare), “ Samphire ” (Orithmum maritimum), ‘ Parsnip” (Pastinaca oleracea), “Cumin” (Cuminum cyminium), “ Carrot” (Daucus carota), ‘“ Cori- ander” (Coriandrum sativum), and a few other less important ones. Amongst the medicinal and poisonous members of the family are the following :—“ Hemlock” (Coniwm maculatuwm), ‘Water Hemlock” (Cicutaria virosa), ‘ Meadow Saffron” (Gnanthe crocata), ‘“‘ Lesser Hemlock” or ‘Fools Parsley” (A?thusia cynapium), ‘‘ Angelica” (Angelica archangelica), ‘‘ Asafotida” (Narthex asafetida), “Gum Ammoniac”’ (Dorema Ammoniacum), and some others. Though the Order contains many useful plants its members should be used with great caution unless well known, especially the uncultivated species, as many deaths have been caused by their injudicious use.

The drupes of Cornus mascula are used in the East in making sherbet. Benthamia- fragifera bears a fruit resembling a strawberry, and has an agreeable taste, and the Aucubas are well known in Europeas ornamental plants Our species is the only one of its genus, and is known in the Cape Colony. as “* Assegai Wood,” and the wood is much esteemed. In Natal the tree is not very plentiful. Number of species about 75. Flowers hermaphrodite, paniculate. Leaves opposite, _ toothed. CURTISEA. 1 Ourtisea, Azt. faginea, A1t. DE. ORDER LXXXIV. RUBIACE. A large and interesting Order. chiefly tropical, but including many species which are found in temperate regions. Of medicinal plants belonging to the family the most important are different species of Cinchona, which yield quinine, and .Cephelis [pecachuanha, yielding the drug of that name. The Cinchonas are trees and shrubs natives of S. America, and the Cepheelis of Brazil. Other species of the Order are also used medicinally. Another and most important member of the Order is Coffea uwrabica, from which, with some other species, the coffee of commerce is obtained. Madder is the dried root of Hubsa tinctorum, and is used by dyers; and Gambir, which is used by tanners, is obtained from Uncaria gambir, a native of the Malay peninsula. Amongst our native species the woods of Bwurchellia capensis, Gardenia Thunhergia, and Rothmannia, Plectronia ventosa and Mundtiana are said to be hard and heavy; but the trees are not large, and the woods have but little commercial value.

A small family whose members inhabit chiefly temperate and cold eountries, few only reaching to warmer climates. Valerian is produced 63 by Valeriana officinalis, and one or two other species, and is a valuable antispasmodic. Celtic Nard is yielded by Valeriana celtica and V. Saliunca. Their roots are used medicinally and to scent baths. Both species are natives of the higher regions of Styria and Carinthia. Spikenard is the product of Na:dostachys Jatamansi, and the young leaves of some of the Valerianellas are used as salad. Our species is of no known value. Number of species about 300. Herb with imparipinnate leaves, and pinky flowers. VALERIANA. 1 Valeriana, Linn. capensis, Thb. B-E, ORDER LXXXVI. DIPSACEA.

Some of them are used medicinally, and some are cultivated for ornament, while the heads of Dipsacus fullorum, the Fuller’s Teazel are used for carding cloth. Our species are of no value. Number of species probably not much exceeding 100. (Ex. TrazeL. Scasrous.) Involucral scales in several rows. Calyx cup-like or discoid. CEPHALARIA. Involucral scales sub 2-seriate.

This is by far the largest family of flowering plants in the veget- able Kingdom, and though in nearly all cases the connection of the different plants to the family is easily seen, referring them to their respective genera is frequently very difficult. Space will not allow more than an enumeration of a few of the more prominent plants which have useful properties. Wormwood, Southernwood, and Tarragon are different species of Artemisia, the Tansy is Pyrethrum tanacetum, the well-known ‘“ Persian Insect Powder ’’ consists of the dried leaves of Pyrethrum cinerarifoliwm, and of some other closely allied species. Arnica is derived from Arnica montana. (auaco, a supposed remedy for the bites of snakes is from oie ee ee hy a. * ~ $e 64. Mikania guwaco, Coltsfoot is a Tussilago, and Safflower Carthamus tinctorius. Chicory is the dried root of Cichoriwm Intybus, and its blanched leaves also are eaten. Salsafy is Tragopogon porrifolius, the Jerusalem Artichoke is Helianthus tuberosus, and the common — Artichoke, Cynara scolymus. The’ seeds of many species yield oils, some of which are said to be equal in flavour to Olive oil. Amongst our indigenous species the timber of Brachylena discolor and some other species, and also of Tarchonanthus camphoratus are said to be good, but the trees are too small to render them of much value. The leaves of Athrivia phylicoides were in the early days of the colony used as a substitute for tea, and the leaves of Bidens pilosa, better known as “‘ Black Jack,” are said to be useful in diarrheea. Number of species verging on to 10,000, though many more than this are enumerated by authors. KEY TO TRIBES. — Heads discoid, or corollas lingulate. Heads discoid or radiate.

From the seeds of Strychnos Nua-vomica, Strychnine is obtained, and the bark of the roots of some other of the genus is highly poisonous. That of S. Tieute, is used by the Javanese to poison their arrows, and in South America two other species are similarly used, and are supposed to be the most active ingredients in the ‘‘Curare.” S. Ignatius yields the Ignatius bean of India, a supposed remedy for Cholera, and 8. potatorum bears the ‘‘ Clearing nut” of India, which clarifies the foul water placed in vessels whose inner surface has been rubbed with this bean. The pulp surrounding the seeds of our native tree 8S. Gerrardi, popularly known as “‘ Gulugulu,” is eaten by natives and children, and the bark of another species is used medicinally by the natives. The wood of another species 8. Atherstoned has been used for staves of casks, but it is not of much value. ‘That of Nuaia floribunda is used by wagon makers, and that of Buddleia salvizzolia is hard and strong, and is said to be suitable for wood engraving, and excellent for wood type ; but the tree is not of large size, Number of species about 350.

Gentiana lutea, a European species, is said to be one of the earliest known medicines. Hrythrea centaurea, the ‘‘Centaury,” has been used as a substitute for it. The Water Trefoil, or Buckbean (Menyanthes trifoliata), has the same properties, and its intensely bitter root is said to be an excellent tonic. None of our species have been tested in this direction so far as known to us. Number of species more than 500, Floating herbs, with long petioled cordate leaves. LIMNANTHEMUM. Terrestrial herbs.

Many species of this Order have been used medicinally, but few, if any, are now so used, except, perhaps, in veterinary practice. Symphytum perigrinum is the “ Prickly Comfrey,” highly recom- mended as food for stock, but it did not find much favour in Natal The ‘‘ Borage” (Borago officinal’s) is well known at home, and is used in the preparation of beverages. Some species of the Order are used as potherbs, and, lastly, several species of Myosotis are known as ‘* Forget-me-not.”’ Number of species about 1200.

An Order whose members are widely distributed in tropical and subtropical countries, more rare in temperate climates. and quite absent from the colder ones. Very many of the species are cultivated for the beauty of their flowers, and some have powerful medicinal properties. Jalap is prepared from the rhizomes of Oonvolvulus J alapa and U. Schtedeanus, but the best quality is said to be obtained from fwogonium purga. Scammony is obtained from Convolvulus scam- monia and C. sagitteefolius of the Mediterranean regions, and Ipomeea pandurata of the U.S. America. Convolvulus dissectus is said to abound in prussic acid, and to be used in the preparation of “ Noyau.”’ Oil of Rhodium is the product of the rootstock of Rhodorhiza sp. The ‘‘ Sweet potato” is Ipomeea batatas, and is too well known to need further reference here. Many of our indigenous species bear handsome flowers, and are well worthy of cultivation. Perhaps the most striking among them is I. Woodzt, first collected in a forest in Zululand. I purpurea has similar properties to Jalap, and is known to the natives as i-Jalapa Number of species about 800.

Some of the species have, however, been unduly multiplied, the well-known Solanum nigrum having received more than 66 names from different authors. The best known members of the Order are the common potato, Solanum tuberosum, originally a native of Peru or Chili, but now unknown in a wild state, the Capsicum or Chilli Capsicum annuum, a native of India, the Tomato, Lycopersicum esculentum of Tropical America, and Tobacco Nicotiana tabacum of Central America. Less well-known species are the Egg plant or Brinjal. Solanum melongena and 8. oviferum are different species of Physalis or Winter Cherry, of which our Cape Gooseberry (Physalis peruviana) is one, and is an introduced species. ‘The Order includes 91 many poisonous plants, such as Belladonna (Atropa belladonna), Stramonium (Datura stramonium), (D. tatula), and (D. metel), Henbane (Hyoscyamus niger). and many others. In fact all of the species, unless well known to be harmless, should be used with caution. Of the species growing in a wild state in Natal, one, 9. capense, has been used by the natives for curdling milk, and some have been used medicinally; but great care should be exercised in their use. Withania somnifera has been used in Natal medicinally by Europeans, it is said with some amount of success; but it is a doubtfully indigenous plant. Number of species 1200 to 1300.

A large Order, whose members are chiefly fonnd in temperate climates, more rare in tropical ones, and in cold and Alpine regions almost absent. Some of the species possess medicinal properties, the most useful of them being the * Foxglove,” Digitalis purpurea, pre- parations of which are in frequent use. It is. nevertheless, a dangerous plant to use except under medical advice. The Brazilian shrub, Brunfelsia uniflora. is a plant often seen in cultivation. Its bark is poisonous, and has been called ‘* vegetable mercury.” A few others have been used medicinally, but none are of much importance. Our indigenous species vary in size from the minute Ilysanthes nana, which is scarcely 2 inches in height, to Halleria lucida and Anastrabe integerrima, which are small trees, and have been used for building purposes. Other genera contain handsome, flowering plants, and Buttonia natalensis is, perhaps. one of our most ornamental climbers ; but hitherto, so far as we are aware, all efforts to cultivate it have been unsuccessful, It is most likely parasitical on some roots, as are the “ Witchweeds,” known to the natives as “ Isona,” which are found in mealie fields and are parasitical on the roots of the mealies and other species of the grass family. They are different species of the genus Striga. Some, if not all of the species of Harveya and Cycnium, have also the reputation of being parasitical. Number of species about 2000. KEY TO THE TRIBES.

LENTIBULARINEAS, A small Order including 4 genera, two only of which are repre- sented in Natal. The genus Utricularia, which is by far the largest genus of the four, takes its name from the bladder-like organs usually found on the submerged leaves of the completely aquatic species. Of these organs De Candolle says: ‘‘ These bladders are rounded and furnished with a kind of movable operculum. In the young plant they are filled with a mucus heavier than water, and the plant, sub- merged by this ballast, remains at the bottom, ‘Towards the flowering season the leaves secrete a gas which enters the utricles, raises the operculum and drives out the mucus, when the plant, now furnished with aerial bladders, rises slowly and floats on the surface, and then flowers. ‘This accomplished, the leaves again secrete mucus, which replaces the air in the utricles, and the plant redescends to the bottom and ripens its seeds in the place where they are to be grown.” (De Candolle. Vegetable physiology). Some, however, of our indigenous species are found on moist rocks and similar places, where there is 97 seldom, if ever, sufficient water to float them, and they are often found on perpendicular rocks, down which the water trickles. Some of the European species have been employed medicinally, but their use is now almost, if not quite, discontinued. Number of species about 180, Calyx of 2 sepals. Utricles bladder-like, ovoid or globose. ; UTRICULARIA. Calyx deeply 5-partite. Utricles tubular with 2 spirally twisted arms. GENLISEA.

Plants of the family have little, if any, economic value; but many are highly ornamental, and are largely cultivated for their beauty. From Streptocarpus Wendlandii of Natal, and S. Dunnii of Transvaal, hybrids of great excellence have been produced, and are now in cultivation in Europe. Other species have also been utilised for the same purpose. Number of species about 700. Stemless herbs, with scape-like peduncles. STREPTOCARPUS. List oF SPECIEs. 1 Streptocarpus, Ld. polyanthus, Hook. AC. angustilobus, N.#.B. F. prolixa, C. B. Clarke, B. Cooperi, 0. B. Clarke.

Many of the species are cultivated for ornament; and in their native countries some have been used medi- cinally, Jacaranda mimosaefolia, in addition to being a very orna- 98 mental flowering tree, is said to yield a handsome and valuable wood. The wood of some of the climbing species represents in section a sort of Maltese cross, resulting from the unequal development of the layers of liber. The well-known Bignonia capreolata has this peculiarity. Two genera only are represented in Natal, each by a single species, and neither of them have any economic value, Number of species about 450.

A small tropical Order, one species only of which is really indi- genous in Natal, Sesamum, which is included here and also in the Flora capensis, is really, | think, an introduced plant, and is cultivated by the natives. Two species only of the family are of much economic value. They are Sesamwm indicum and S. ordentale. Their seeds yield a valuab'e oi', chiefly used in the manufacture of soap. These plants are largely cultivated in India and on the East coast of Africa. Several species of Martynia bear curious hooked seed vessels, and are not uncommon in cultivation. Uncaria procumbens, the ‘‘ Grapple” plant of South Africa, formerly included in this Order, has now been removed to the Order Rubiacezee. Our only species of the Order is a somewhat showy weed when in flower, and has lately been introduced into cultivation at home. Number of species about 40. Capsule acute or acuminate at apex. SESAMUM. Capsule 5-horned at apex. CERATOTHECA, List oF SPECIES. 1 Sesamum, Linn. 2 Oeratotheca, Endl. indicum, D.C. A. triloba, H.M. AB. ORDER CXXII ACANTHACEA, A large and well-known family, which is represented all over the world, except in the coldest climates. None of the species are used medicinally in Europe, though in the countries where they are indigenous they are sometimes employed as tonics, febrifuges, ete. In India one species has some reputation as a remedy for rheumatism, and another yields the blue “Room” dye. A French tonic, “ Drogue amere,”’ is the tincture of Justicia paniculata with other ingredients added. Acanthus mollis is the plant whose leaves have been copied 99 as ornaments for the Corinthian pillars. The roots of Rhinacanthus communis, boiled in milk, have been used for the cure of ringworm, and also for snake bites. The Order includes from 1300 to 1400 species. KEY TO TRIBES.

A small family containing 10 genera only, of which six or seven are almost confined to Central and South Africa—one Asian and one from the Mediterranean region and the Canary Islands. In Natal we have three genera only. MHebenstreitia is wholly South African. Walafrida has an outlying species in Madagascar.

Two, however, of the exotic genera are well known. ‘The first, Bougainvillea, is a native of South America, and is common in our gardens, the other is Mirabilis Jalapa, or ‘“‘ Marvel of Peru,” which was probably brought by the early settlers, and may occasionally be seen in a semi-wild state in the vicinity of the towns. Its roots are said to be purgative and emetic. Several species of Boerhaavia have also been used medicinally, but they are not of much value Our species bear rather pretty flowers. but have no economic value, nor are they used by the natives in any way.

The genus from which this family takes its name is Urtica, and the common stinging nettle is Urtica dioico; this genus includes some 30 species, most if not all of which are furnished with stinging hairs, as also are those of some of the nearly related genus Fleurya, but the most virulent of all of them are probably one or more species of Laportea, an Australian species of this genus which is said to cause much suffering or even death to animals which have been much in contact with it. An Indian species emits when bruised so ‘irritant an effluvia as to cause a copious flow of saliva and mucus from the nose and eyes for many hours, and sometimes to produce violent fever, and a Timor species of Urtica is said to have caused death. The different species of Morus known popularly as “ Mulberries” belong to this Order, and are cultivated for their fruit, and also for their leaves which are used as food for silkworms. The species of Ficus or “ Figs” are trees or climbing shrubs many of which are parasitical in their early life, and after having killed their host lead an independant existence; some of the species yield caoutchouc; the most important of these is Ficus elastica, a native of India, and some of the other species are the food plants of the “Lac” insect. What is popularly known as ‘“‘China Grass” is the fibre from the bark of two or more species of Beehimeria, and is rapidly becoming an important article of commerce. The ‘‘ Bread-fruit” is Artocarpus incisa, and the “Jack” A. inte- grifolia, and both belong to this Order, as also does Brosimum galactodendron, the so-called “* Cow tree” of Venezuela, the useful properties of which have most likely been greatly exaggerated, as also have the deleterious properties of Antiaria toaicaria, the “ Upas” tree about which so many highly coloured reports have been spread. Finally several species of the Order yield valuable wood, and the bark of others has been used medicinally. Number of species about 1500. Ovules pendulous. A. Ovules erect. B. A. OVULES PENDULOUS.

The genus from which this Order takes its name is the only one of the family, and includes some 25 species which are widely dis- tributed. They are shrubs or small trees, the bark of one species has been used medicinally, and the root of another is emetic and purgative. The berries of some of the species are covered with a waxy secretion, and this wax when separated has been, and still no doubt is, used in the manufacture of candles. Myrica Gale the ‘“‘Sweet Gale” or ‘ Bogwort”’ is the badge of the Campbells. Our indigenous species have no economic value. Flowers unisexual. Shrubs with simple serrate leaves. Myrica.

A family containing two genera only, Salix the *‘ Willow,” and Populus the ‘‘ Poplar,” the first named having the largest number of species. The bark of several species of Salix yield salicine, which is used medicinally, and the buds of some species of Poplar have also been used as medicine. ‘The shoots of several species of Salix are valued as “ Osiers,” and the wood of many species of both genera for lightness and strength, and is used for many purposes. It is as yet doubtful whether more than one species is indigenous in Natal. Number of species 150 to 200.» A shrub or small tree with narrow linear leaves. SALIX. L Salix, Linn. Wood, Seem. DE. ORDER CLXIU. CERATOPHYLLE. A small family of aquatic plants including one genus only, and though 8 or 10 species have been enumerated, it is thought that there are most likely not more than two or three distinct species. They have no useful properties, and are quite without value. Our only. species was found in a stagnant pool near the mouth of the Umgeni, and it has not been specifically identified on account of the absence of complete specimens.

A family of trees, rarely shrubs, whose uses are many and various ; the timber of many of the species is in use all over the world, and is known as “ Pine,” Deal, Pitch-Pine, &c, Turpentine is obtained by incissions made in the bark, the products being afterwards refined Venice Turpentine is a superior kind yielded by Laria ewropea. Rosin, Pitch and Tar are the produce of many species, and are obtained from the residuum after the more volatile turpentine has been extracted. Canada balsam is yielded by Abies balsamina, and Gum Dammar by the different species of Dammara, natives of New Zealand, where the trees grow to a large size; their wood is also much used and is known as ‘‘ Kauri Pine,” a name which is often confused with ‘Karri,’ a valuable wood yielded by Eucalyptus diversicolor. Our native species of Podocarpus are known as ‘ Yellowwood,” and our only species of Callitris as ‘‘Cedar’’ or ‘Cypress,’ the latter tree being found in certain parts of the Drakensberg only. (ex.

The stigmas of Crocus sativa are dried and used as a yellow dye, and «lso medicinally, they form the “ Saffron’ of commerce. Many of our indigenous species of the Order bear handsome flowers, more especia'ly those of Gladiclus, Watsonia and Tritonia, while the tubers of some species of Moreea are said to be poisonous. and the leaves are called by the Dutch and Colonists “'Tulp” or “ Tulip,’ and are certainly deleterious to cattie.

An Order containing a very large proportion of ornamental plants, some of which, such as the species of Crinum, Clivia, and Hzemanthus amongst African genera, and Narcissus, Pancratium, Bomarea, and others among-t foreign genera are very showy, while the Snowdrop (Galanthus nivalis) and the Snowflake (Leucojum vernum) are more admired for the gracefulness of their flowers, and the latter for its scent also. Both are natives of northern climates. Some species of the family have the reputation of being poisonous, but it is quite possible that their deleterious properties have in some cases been exagge- rated. The well-known ‘‘ American Aloe” belongs to this Order, and is not an Aloe, its correct name being Agave americana; its leaves yield a very strong fibre, and the Mexicans obtain from its sap a liquid, which, when fermented is known as “ Pulque,” and is very intoxicating. What is known locally as “ Mauritius Hemp,” is obtained from one or more species of Furcrza, plants which are also incorrectly called Aloes; these plants are also natives of South America, but are being largely cultivated in many parts of the world. Number of species about 650. KEY TO TRIBES. Rootstock a tunicated corm. Spathe not present. Flowers usually yellow, hairy outside. A. HypoxIpE@. Rootstock a tunicated bulb.

DIOSCORACEA. A small family containing 8 genera only, two of which are repre- presented in Natal; the genus Testudinaria being peculiar to South Africa. The tubers of several species of Dioscorea are the “‘ Yams,” so much used as articles of food in most tropical countries. None of our indigenous species have any economic value. The rootstock or tuber of /'estudinaria sylvatica which lies on the surface of the ground is in good specimens singularly like a Tortoise. Number of species less than 200. Tuber fleshy, subterranean, Seeds winged all round, or at base only. DioscorEA. Tuber on surface of ground. Seeds winged at apex only. ‘TESTUDINARIA.

A large family including Smilaceze and Melanthacese which in Harvey’s Genera of South African Plants form distinct Orders. Many species of the Order are remarkable for the beauty of their flowers, and others for the properties they possess. Amongst the former, the Tulips and Lillies probably stand foremost, but the Hyacinth, - - 134 Tuberose, Agapanthus, Kniphofia, Fritillaria and others are highly esteemed as ornamental flowering plants. ‘The bulbs of Tulipa, Scilla and of some other genera have been used medicinally, but are now little esteemed. The leaves of Phormium tenuzx the “ New Zealand Flax” yield a fibre which is used for cordage and other purposes. The drug known as Aloes is extracted from several species of Aloe, that yielded by a species growing in the island of Socotra being considered the best, the species principally used for this purpose in Natal is Aloe ferox, thougb probably other species have been used, though not in quantity. Several species of Allium are used in cookery, such as the following: Onion, Eschalot, Leek, Garlic, Chives and others. Sarsa- parilla is the root of several species of Smilax, and these roots are sent to Kurope in large quantities from South America, but we are not aware whether our only indigenous species of the genus has been tested for its medicinal properties. Many of our native species of the Order are very ornamental, and though the individual flowers are not large, the large number of them on each stem in some measure com- pensates for their smaller size; the flowers on one spike of some of the Kniphofias, for instance are very numerous, those of K. multiflora reaching to 3-400 or perhaps more on a single spike. Several of our native species of Asparagus are in cultivation in Kurope, and are highly esteemed, A. plumosus nanus being known everywhere, while A. virgatus has been cultivated as a culinary vegetable.
