When they have 4 to 6 leaves and are thrifty little plants, it's time to set them out where they are to remain.

When Siamese cats are intertwined it is difficult to tell where one leaves off and another begins.

Algae lack the various structures that characterize land plants, such as phyllids ( leaves ) and rhizoids in nonvascular plants, or leaves, roots, and other organs that are found in tracheophytes ( vascular plants ).

Carrot, celery and parsley are true biennials that are usually grown as annual crops for their edible roots, petioles and leaves, respectively.

Almost all species have a tight cluster of leaves ( a rosette ), either at the base of the plant or at the end of a more-or-less woody stem ; the leaves are less often produced along the stem.

Only in a few cases are leaves produced along the length of the stem.

They are upright perennial herbs ( to about 1. 50 m ), with distinctive leaves.

They are more or less rhizomatous, with spiral leaves and an inflorescence that may form a raceme or a spike.

They are herbs with corms and leaves which are sometimes stalked ( petiolate ) with wide blades.

Members of the family are usually perennial herbs with sword-shaped unifacial leaves ; the inflorescence is a spike or panicle of solitary flowers, or forms a monochasial cyme or rhipidium ( meaning that the successive stems of the flowers follow a zig-zag path in the same plane ); and the flower has only three stamens, each opposite to an outer tepal.

The leaves form a rosette at the base of the plant, and are alternate, distichous, flat, sessile, simple, linear or lanceolate, and parallel veined, with entire margins.

They are relatively robust herbaceous perennials with short rhizomes and leaves forming a rosette, individually linear-oblong, flat, rather fleshy.

The flowers are quite large, blue or white, forming an umbel at the end of a stem ( scape ) which is longer than the leaves.

They are herbaceous perennials with bulbs, and can be identified by their rather fleshy leaves, usually large and attractive flowers, with six stamens and an inferior ovary.

Most Apiaceae are annual, biennial or perennial herbs ( frequently with the leaves aggregated toward the base ), though a minority are shrubs or trees.

Their leaves are of variable size and alternately arranged, or alternate with the upper leaves becoming nearly opposite.

The leaves are 3 – 5 inches long, with a serrated margin and a petiole.

The flowers are white to pale pink, diameter with five petals, produced singly or in pairs and appearing before the leaves in early spring.

Through application of elementary row operations and the Gaussian elimination algorithm, the left block of B can be reduced to the identity matrix I, which leaves A < sup >− 1 </ sup > in the right block of B.

The human sperm cell is the reproductive cell in males and will only survive in warm environments ; once it leaves the male body the sperm's survival likelihood is reduced and it may die, thereby decreasing the total sperm quality.

Because of its low molecular weight, helium enters and leaves tissues more rapidly than nitrogen as the pressure is increased or reduced ( this is called on-gassing and off-gassing ).

The above ground parts of Trilliums are scapes with three large, leaf-like bracts with the true leaves reduced to underground papery coverings around the rhizomes.

In many of the latter, buds are even more reduced, often consisting of undifferentiated masses of cells in the axils of leaves.

** scaly or covered, when scales ( which are in fact transformed and reduced leaves ) cover and protect the embryonic parts ;

A Corinthian capital may be seen as an enriched development of the Ionic capital, though one may have to look closely at a Corinthian capital ( illustration, right ) to see the Ionic volutes (" helices "), at the corners, perhaps reduced in size and importance, scrolling out above the two ranks of stylized acanthus leaves and stalks (" cauliculi " or caulicoles ), eight in all, and to notice that smaller volutes scroll inwards to meet each other on each side.

Smaller leaves are preferred ; however, any bitter taste of larger leaves can be reduced by pouring off the water from initial boiling and replacing it with fresh water.

The mandibles are tough and sharp for chewing leaves ( this contrasts with most adult Lepidoptera, which have highly reduced or soft mandibles ).

This leaves the projectile traveling at high velocity with a smaller cross-sectional area and reduced aerodynamic drag during the flight to the target ( see external ballistics and terminal ballistics ).

Dodder can be identified by its thin stems appearing leafless, with the leaves reduced to minute scales.

Water loss is reduced by the resinous, waxy coating of the leaves, and by their small size which prevents them from heating up above air temperature ( which would increase the vapor pressure deficit between the leaf and the air, and thus would increase water loss ).

The hybrid has leaves imparipinnate, with leaflets semipersistent, subsessile terminal and sometimes reduced.

* Leafy inflorescences: Though often reduced in size, the bracts are unspecialised and look like the typical leaves of the plant, so that the term flowering stem is usually applied instead of inflorescence.

At higher altitudes smaller-leaved species grow, and in alpine areas there are whipcord species with leaves reduced to thick scales.

Botanically these represent reduced leaves, so strictly it is not quite correct to call this plant fully " leafless ".

This leaves the town with a vastly reduced population density of approximately 19. 87 / sq mi ( 7. 67 / km² ).

In root-tubers, there are no nodes and internodes or reduced leaves.

At one stage, Zita was reduced to making salad and spinach dishes from dandelion leaves.

His search leaves him with a reduced sensitivity: right after being confronted with his father's death, Anicet breaks out in tears only after sitting through an entire dinner.

All the dominant overstorey Acacia species and a majority of the understorey Acacias have a scleromorphic adaptation in which the leaves have been reduced to phyllodes consisting entirely of the petiole.

By cooking and discarding the water the bitterness is reduced, after which the chicory leaves may be sauteed with garlic, anchovies and other ingredients.

They have reduced their pseudobulbs and instead, some species have thick succulent leaves.

But in some species, the leaves may be reduced or have become brown scales.
