Innumerable clusters of wild cherries (Prunus Chamaecerasus), wild apricots (Amygdalus nana), the Siberian pea-tree (Caragana frutescens), and other deep-rooted shrubs grow at the bottoms of the depressions and on the slopes of the ravines, imparting to the steppe that charm which manifests itself in the popular poetry.

None of them were in clusters, such as villages or towns, but each had ample grounds of its own, with orchards and gardens surrounding it.
However, on this, the shaded west side, aided by the steady flow from the tapped pipe, massive icicles, bulges and clusters coated the side.
Both present the appearance of diminutive clusters of grapes, at the anterior end of the kidneys, close to the suprarenal bodies, separated from each other by the descending aorta and by the vena cava where this is formed by the right and left vena iliaca communis.
On the dome-like tops of such mountains as are too high for trees are large clusters of rhododendrons and patches of grasses fringed with flowers.
The most common are the Natal lily with pink and white ribbed bells, the fire-lily, with flame-coloured blossoms, ixias, gladiolas, the Ifafa lily, with fuchsia-like clusters, and the arum lily.
In its lower course, whatever is worthy of record clusters round the historical vicissitudes of Hamburg - its early prominence as a missionary centre (Ansgar) and as a bulwark against Slav and marauding Northman, its commercial prosperity as a leading member of the Hanseatic League, and its sufferings during the Napoleonic wars, especially at the hands of the ruthless Davotit.
The small inconspicuous flowers are generally more or less crowded in terminal or lateral clusters, the form of the inflorescence varying widely according to the manner of branching and the length of the pedicels.
Jalap has been cultivated for many years in India, chiefly at Ootacamund, and grows there as easily as a yam, often producing clusters of tubers weighing over 9 lb; but these, as they differ in appearance from the commercial article, have not as yet obtained a place in the English market.
Dumont d'Urville describes four such villages in the Bay of Dorei, containing from eight to fifteen blocks or clusters of houses, each block separately built on piles, and consisting of a row of distinct dwellings.
These clusters present many unsolved problems. Thus Perrine, from an examination of ten globular clusters (including Messier 13 and Centauri), has found in each case that the stars can be separated into two classes of magnitudes.
They are shrubs or low trees with evergreen or nearly evergreen opposite entire leaves, and dense clusters of small, white, tubular four-parted flowers, enclosing two stamens and succeeded by small, globular, usually black berries, each with a single pendulous seed.
The main distinction is the occurrence in the tissue of the fruit, or beneath the rind, of clusters of cells filled with hard woody deposit in the case of the pear, constituting the "grit," while in the apple no such formation of woody cells takes place.
The firs are distinguished from the pines and larches by having their needle-like leaves placed singly on the shoots, instead of growing in clusters from a sheath on a dwarf branch.
The canals between these clusters of houses were deepened and cleared out, and in some cases trees were planted along the banks, or fondamenta; we hear of the cypresses on San Giorgio Maggiore, of an ancient mulberry tree at San Salvadore, of a great elder tree near the Procuratie Vecchie where the magistrates were wont to tie their horses.
Such a wall would be required to protect the clusters of dwellings around the Acropolis as well as the springs issuing from the rock, while the gates opening in various directions would give access to the surrounding pastures and gardens.
The point of this leading shoot is subsequently pinched off, that it may not draw away too much of the sap. If the fruit sets too abundantly, it must be thinned, first when as large as peas, reducing the clusters, and then when as large as nuts to distribute the crop equally; the extent of the thinning must depend on the vigour of the tree, but one or two fruits ultimately left to each square foot of wall is a full average crop. The final thinning should take place after stoning.
Some are globular and others are rod-shaped; they may be grouped in clusters, stars, rosettes, rows, chains or swarms of indefinite shape.
The alpine rose (Rhododendron dauricum) clusters in masses on the higher mountains; juniper, spiraea, sorbus, the pseudo-acacia (Caragana sibirica and C. arborescens, C. jubata in some of the higher tracts), various Rosaceae - Potentilla fruticosa and Cotoneaster uniflora - the wild cherry (Prunus Padus), and many other shrubs occupy the spaces between the trees.
But the chief ornament of Lebanon is the Rhododendron ponticum, with its brilliant purple flower clusters; a peculiar evergreen, Vinca libanotica, also adds beauty to this zone.
The margins of these leaf-like branches are more or less crenately notched, the notches representing buds, as do the spine-clusters in the spiny genera; and from these crenatures the large showy flowers are produced.
Several fine star clusters also appear in this constellation.
The flowers are generally arranged in terminal or axillary clusters, and are markedly regular with the same number of parts in each series.
Long, of a light shining brown hue, with thick scales terminating in a pyramidal apex; they are arranged around the branches in the radiating clusters that give name to the tree.
Certain clusters contain a remarkable number of short-period variables.
Doubtless with improved telescopes many more apparent nebulae would be shown to be clusters, but there are certainly many nebulae which are otherwise constituted.
Many of the clusters are of very irregular forms, either showing no well-marked centre of condensation, or else condensed in streams along certain lines.
There is, however, a well-marked type to which many of the richest clusters belong; these are the globular clusters.
The question of the stability of these clusters is one of much interest.
If this surmise be correct, we are witnessing in clusters a counter-process of progress of a nova.
This may explain the existence of gaseous nebulae, which are often found intimately associated with star-clusters, a good example being the nebulosity surrounding the Pleiades.
(WolfRayet) stars; in their case the condensation into the galactic regions is complete, for of the 91 known stars of this type, 70 are actually in the Milky Way and the remaining 21 are in the Magellanic Clouds (two large clusters in the southern hemisphere, which resemble the Milky Way in several respects).
The flowers are sweet-scented, in flat-topped clusters, and 2 to 4 in.
The town clusters at the foot of the monastery of St John, which, crowning the hill with its towers and battlements, resembles a fortress rather than a monastery.
