They shelter in crevices of the bark of trees, in the dried stems of herbaceous plants, or among moss and fallen leaves on the ground.
Axillary or terminal spikes; they have four stamens, which bear at the back four small herbaceous petal-like structures, and four free carpels, which ripen to form four small green fleshy fruits, each containing one seed within a hard inner coat;.

In the most generally used sense, a plant is a member of the lower or vegetable order of living organized things; the term is also popularly applied to the smaller herbaceous plants, thus excluding trees and shrubs.
It should be remembered that a single complete defoliation of a herbaceous annual may so incapacitate the assimilation that no stores are available for seeds, tubers, &c., for another year, or at most so little that feeble plants only come up. In the case of a tree matters run somewhat differently; most large trees in full foliage have far more assimilatory surface than is immediately necessary, and if the injury is confined to a single year it may be a small event in the life of the tree, but if repeated the cambium, bud-stores and fruiting may all suffer.
Spotted Leaves, &c.Discoloured spots or patches on leaves and other herbaceous parts are common symptoms of disease, and often furnish clues to identification of causes, though it must be remembered that no sharp line divides this class of symptoms from the preceding.

Excrescences may be divided into those occurring on herbaceous tissues, of which Galls are well-known examples, and those found on the woody stem, branches, &c., and themselves eventually woody, of which Burrs of various kinds afford common illustrations.
Conditions of hyper-turgescence are common in herbaceous plants in wet seasons, or when overcrowded and in situations too moist for them.
Pythium, Peronospore, Completoria, Vol utelta, Botrytis, &c. That such overturgescence should lead to the bursting of fleshy fruits, such as gooseberries, tomatoes and grapes, is not surprising, nor can we wonder that fermentation and mould Fungi rapidly spread in such fruits; and the same is true for bulbs and herbaceous organs generally.
Comparable with these cases is that of Cuckoo-spit, due to the juices sucked out by Aphrop/ttkora~ on herbaceous plants of all kinds.
It is characterized by its needle-leaved Coniferae, its catkin-bearing (Amentaceae) and other trees, deciduous in winter, and its profusion of herbaceous species.
Herbaceous plants are rare and mostly epiphytic.
Sequoia and the tulip-tree still remain; figs are abundant; laurels are represented by Sassafras and camphor; herbaceous plants (Ranunculaceae, Cruciferae, Umbelliferae) are present, though, as might be expected, only fragmentarily preserved.
If we turn to herbaceous plants, Hemsley has pointed out that of the thirteen genera of Ranunculaceae in California, eleven are British.
The former support a copious herbaceous flora, the characteristics of which in the Old and New Worlds have been already briefly summarized.
It is even richer in more herbaceous plants tolerant of a hot summer; giant Umbelliferae (such as Ferula) are especially characteristic and yield gum-resins which have long been reckoned valuable.
The vegetable-feeders attack leaves, herbaceous or woody stems and roots; frequently different parts of a plant are attacked in the two active stages of the life-history; the cockchafers, for example, eating leaves, and their grubs gnawing roots.
It is covered with a thick sheet of black earth, a kind of loess, that is mixed with humus.
Mosses and lichens are distinctive, as also are the birch, the dwarf willow and several shrubs; but where the soil is drier, and humus has been able to accumulate, a variety of herbaceous flowering plants, some of them familiar in W.
On the other hand, several Asiatic species (Siberian pine, larch, cedar) grow freely in the N.E., while numerous shrubs and herbaceous plants, originally from the Asiatic steppes, have found their way into the S.E.
The moist soil encourages luxuriant thickets of willows (Salicineae), surrounded by dense chevaux-de-frise of wormwood and thornbearing Compositae, and interspersed with rich but not extensive prairies, harbouring a great variety of herbaceous plants; while in the deltas of the Black Sea rivers impenetrable beds of reeds (Arundo phragmites) shelter a forest fauna.
The number of species of herbaceous plants rapidly increases, while beyond the Volga a variety of Asiatic species are added to the W.
Of the herbaceous vegetation of the more rainy regions may be noted the Orchidaceae, Orontiaceae, Scitamineae, with ferns and other II.
In the spring there is an abundant herbaceous vegetation, including many bulbous plants, with genera, if not species, identical with those of the Syrian region, some of which extend to the Himalaya.
The plateau, known as the Ogaden plateau, everywhere presents the same monotonous aspect of a boundless steppe clothed with a scanty vegetation of scrubby plants and herbaceous growths.
Of herbaceous plants the kissenia, the sole representative of the order Loasaceae, which is common in America but very rare elsewhere, is found in Somaliland, which also possesses forms belonging to the eastern Mediterranean flora.
The term "herb" is also used of those herbaceous plants, which possess certain properties, and are used for medicinal purposes, for flavouring or garnishing in cooking, and also for perfumes.
It is an order of herbaceous FIG.
Of the Old World; it has a short creeping rhizome, from which springs a slender, herbaceous or woody, often very much branched, erect or climbing stem, the ultimate branches of which are flattened or needle-like leaf-like structures (cladodes), the true leaves being reduced to scales or, in the climbers, forming short, hard more or less recurved spines.
The plants are hardy herbaceous perennials with narrow tufted radical leaves and an elongated stem bearing a handsome spike of white or yellow flowers.
The jalap plant has slender herbaceous twining stems, with alternately placed heart-shaped pointed leaves and salver-shaped deep purplish-pink flowers.
The plants are generally herbaceous, often, however, reaching a gigantic size, but are sometimes shrubby, as in Pothos, a genus of shrubby climbing plants, chiefly Malayan.
The order is represented in Britain by Arum maculatum, a low herbaceous plant common in woods and hedgerows in England, but probably not wild in Scotland.
Of 1500 species of herbaceous plants in the Red river basin, it is estimated that fully half reach here their geographical limit or limit of frequent occurrence.
He divided them into eighteen classes, distinguishing plants according as they were woody or herbaceous, and taking into account the nature of the flowers and fruit.
The name Ambrosia was also applied by Dioscorides and Pliny to certain herbs, and has been retained in modern botany for a genus of plants from which it has been extended to the group of dicotyledons called Ambrosiaceae, including Ambrosia, Xanthium and Iva, all annual herbaceous plants represented in America.
In the " bush " are found tufts of tall coarse grass with the space between bare or covered with herbaceous creepers or water-bearing tubers.
In Ontario the flora of the northern part is much the same as that of the Gulf of St Lawrence, but from Montreal along the Ottawa and St Lawrence valleys the flora takes a more southern aspect, and trees, shrubs and herbaceous plants not found in the eastern parts of the Dominion become common.
At the beginning of the elevation of the Rocky Mountains there is a luxurious growth of herbaceous plants, including a number of rare umbellifers.
The term is loose in application and the line between shrubs, trees and certain woody herbaceous plants is not easy to draw.

These do not reach exactly to the same elevation, nor are they often found growing together; but their upper limit corresponds accurately enough to the change from a temperate to a colder climate that is further proved by a change in the wild herbaceous vegetation.
Their functions in annual, biennial and herbaceous perennial plants cease after the ripening of the seed, whilst in plants of longer duration layer after layer of strong woody tissue is formed, which enables them to bear the strains which the weight of foliage and the exposure to wind entail.
Indeed, any low-growing herbaceous plant, susceptible of minute division, is suitable for an edging.
For larger masses, such as stronggrowing herbaceous plants, a spade or digging-fork will be requisite and the soil may be trodden down with the feet.
Hardy Herbaceous Perennials.
- ThiS term includes not only those fibrous-rooted plants of herbaceous habit which spring up from the root year after year, but also those old-fashioned subjects known as florists' flowers, and the hardy bulbs.
