Loddiges, bearing the name of F. O'mus

globífera. Spec. Char., &c. Leaves with 3—4 pairs of lanceolate or elliptic, attenuated,

serrated, stalked leaflets, which are entire at the base, villous or downy beneath. Flowers greenish white. Peduncles axillary, solitary, shorter than the leaves. Flowers complete or hermaphrodite. Young branches purplish or livid, with yellow dots. Buds cinereous. (Don's Mill., iv. p. 56.) A tree, from 20 ft. to 30 ft. high ; a native of the south of Europe. Introduced in 1730, and flowering in May and June.

Properties and Uses. This species, the following one, and, probably, all those of both the genera Fraxinus and Oʻrnus, extravasate sap, which, when it becomes concrete, is mild and mucilaginous. This sap is produced in more abundance by Oʻrnus europæ'a and 0. rotundifolia, than by any other species; and, collected from these trees, it forms an article of commerce

under the name of manna, This substance is chiefly collected in Calabria and Sicily; where, according to the Materia Medica of Geoffroy, the manna runs of itself from the trunks of some trees, while it does not flow from others unless wounds are made in the bark. Those trees which yield the manna spontaneously grow in the most favourable situations; and the sap runs from them spontaneously only during the greatest heats of summer. It begins to ooze out about mid-day, in the form of a clear liquid, which soon thickens, and continues to appear till the cool of the evening ; when it begins to harden into granules, which are scraped off the following morning. When the night has been damp

a

or rainy, the manna does not harden, but runs to the ground, and is lost. This kind is called manna in tears, or manna lagrimi; and it is as pure and white as the finest sugar. About the end of July, when the liquid ceases to flow of itself, incisions are made through the bark and soft wood; and into these incisions slender pieces of straw or twig are inserted, on which the manna runs, and, coating them over, hardens on them. This is the common manna of the shops, which is thus collected in the form of tubes; and it is called manna in cannoli, or manna cannoli

. Another and inferior sort is procured by making an oblong incision in the trees, in July or August, and taking off a piece of the bark about 3 in. in length, and 2 in. in breadth. This kind, which is called manna grassa, is the coarsest; but, as it is produced with least trouble, and in great abundance, it is also the cheapest. Sometimes, instead of cutting out a piece of bark, and leaving the wound open, two horizontal gashes are made, one a little above the other; in the upper of which is inserted the stalk of a maple leaf, the point of the leaf being fixed in the lower gash, so as to form a sort of cup to receive the manna, and to preserve it from dust and other impurities. The greater part of the manna of commerce is procured in the latter manner; and it is imported in chests, in long pieces, or granulated fragments, of a whitish or pale yellow colour, and in some degree transparent. The inferior kind is of a dark brown colour, in adhesive masses, and is moist and unctuous when felt. Manna from the ash has a peculiar odour, and a sweetish taste, accompanied with a slight degree of bitterness. It is considered aperient; was formerly much used in medicine; but is now chiefly used to disguise other drugs in administering them to children. This manna must not be confounded with the manna of the Scripture, which, as already observed (P.646.) is obtained from the Alhàgi Mauròrum, and is known in the East, in modern times, as the Persian or Syrian manna; or with the Arabian manna, which, Burckhardt tells us, is obtained from the tamarisk. A similar substance is also obtained from the larch in the south of France, where it is known by the name of manne de Briançon The rhododendron, the walnut, and the beech, also, yield an analogous substance, as, probably, do various other trees; for the sap of most ligneous plants is more or less sweet and mucilaginous; and, consequently, when collected in any quantity, susceptible of becoming concrete by evaporation. The manna of Lebanon is the gum mastic; and the manna of Poland is composed of the seeds of Glycèria flùitans. The seeds of 0. europæ'a and of 0. (e) rotundifolia are small, as exhibited in fig. 1065; they have an aromatic flavour, and are very generally em

1065 ployed, in Egypt, for seasoning food. (Dict. Clus. d'Hist. Nat.; Nouveau Cours d'Agric., &c.) This and the other species of Oʻrnus are commonly propagated by grafting on Fráx

1066 inus excélsior;

and as the stock in this case is a much more vigorous-growing plant than the scion, when the graft has been made a foot or more above ground, the stock enlarges on every side, so much more than the scion, as to produce the appearance of the base of a column, as in fig. 1066. c; and, if, after the scion of O'rnus had grown to the height of 20 ft. or 30 ft., it were headed down to 10 ft. or 12 ft. and budded or grafted with the common ash, the scion would enlarge on every side; and if again headed down to within a foot of the second graft, and regrafted with O'rnus, the appearance of the capital of a column would be produced, as

a

of fig. 1066. d. If, again, a stock of the common ash were grafted with O'rnus, and, after it had grown one year, were headed down to within 14 ft. or 2 ft. of the graft, and a scion of the common ash inserted ; and, at the end of the year, if the shoot produced were grafted with O'rnus at the same distance as before, and if this practice were continued, and O'rnus and Fraxinus grafted alternately at regular distances, till the stem had attained the height of a column, say of 10 ft. or 12 ft., the appearance, after the tree had grown for some years, would be as in fig. 1066. b; which is what architects call a rusticated column. Again, if O'rnus were made the stock, and the common ash grafted on it, and allowed to grow till it attained the height of a column, and if it were then grafted with O'rnus, the appearance would be as in fig. 1066. a, which is that of the Roman fasces, or of a column formed out of spears. The most singular tree of O'rnus europæ'a, perhaps, in Europe, is that noticed by Dr. Neill, as growing in the Leyden Botanic Garden in 1817. In the Journal of a Horticultural Tour &c., p. 153., an engraving is given of this tree, together with its dimensions; and fig. 1067. is a copy of this engraving, reduced to a scale of 1 in. to 12 ft. This tree was planted in the time of Boerhaave, and, it is reported, was grafted by the professor himself; it must, therefore, be considerably above 100 years old. Its trunk in 1817 was nearly 12 ft. high; and from the ground to the summit of the

1067 branches was about 24 ft. The sloping bark at the junction of the stock and graft was quite smooth and complete all round; a fact, Dr. Neill observes, that would seem to indicate that the stock and graft had originally been nearly adapted to each other with regard to size. “ All roundthe stem are numerous knobs and distorted protuberances, producing the most singular effect. In no place, however, is there any appearance of canker or disease, the bark being every where healthy. The stem is crowned by a thicket of irregular and crowded branches, which form, upon the whole, a fine round head.” (Hort. Tour, p. 134.) While the revise of this sheet is before us, we have received the dimensions and a portrait of this tree in its present state, through the kindness of Professor Reinwardt of Leyden. It is still a curious tree, but from age and decay considerably different from the figure above given.

Many oddities of this kind might be produced by the curious gardener. The idea of suggesting them occurred to us some years ago, on seeing a very remarkable specimen in the New Cross Nursery, which has been since removed. There is one at Purser's Cross, and some at Syon ; though the largest tree in the latter place (of which an engraving is given in our last Volume) appears to be either a seedling plant, or grafted under the surface of the ground, as no protuberances appear. At Kew, there is one, of which fig. 1068. is a sketch (e being a view from one side, and f a view from the opposite side), which is to our scale of 1 in. to 12 ft. There is also a fine specimen of Oʻrnus americana at Kew, grafted on the common ash; but, as the growth of the two species is nearly alike, there is less difference between the scion and the stock. (See fig. 1071. in p. 1245.) At Gunnersbury, the same

f effect, and to the same extent, has been produced by grafting the variegated on the common sycamore; and, indeed, a similar result may be obtained by grafting any slow-growing tree on a fast-growing one.
