The stamens are a little shorter than the perianth segments; and their filaments are clothed with white woolly hairs.
The perianth falls early; and the ovary afterwards becomes a berry-like fruit with a single stone.
The male flowers have four stamens, and a small, green perianth of four segments; while the females consist of an ovary with a tufted stigma, surrounded by a perianth of four segments the two inner of which are larger, or of two segments only.
Those of the Stonecrop group usually have cymes of flowers with perianth leaves in whorls of five, and stamens in two whorls.
The perianth is composed of a tube and six spreading limbs of a delicate yellow colour; and a deep, bell-shaped, golden coronet, beautifully notched and curled at the rim.
The latter are imperfect, with a deeply-cleft perianth of six lobes.
The segments of the perianth are very sharp, about an eighth of an inch long, with membranous margins; and the capsules are blunt.
The inner segment of the perianth is enlarged, ovate, distinctly toothed, with a long point.
The perianth is cleft into six parts, of which the three outer are smaller and covered with little tubercles, while the inner become enlarged and close over the triangular fruit.
The flowers are in crowded whorls, on slender pedicels which are longer than the perianths; and the inner segment of the perianth is enlarged, cordate, but not toothed.

After fertilization, some of the uppermost bracts below each flower become red and fleshy; the perianth develops into a woody shell, while the integument remains membranous.
The presence of a perianth is a feature suggestive of an approach to the floral structure of Angiosperms; the prolongation of the integument furnishes the flowers with a substitute for a stigma and style.
A single male flower consists of an axis enclosed at the base by an inconspicuous perianth formed of two concrescent leaves and terminating in two, or as many as eight, shortly stalked or sessile anthers.
A, i), prolonged upwards as a narrow tube and succeeded by an inner and an outer perianth (fig.

In some cases the petals may be lacking, the one set of perianth parts represented being regarded as the calyx, although it may look like a corolla, as in the clematis or anemone.
Britain by several species in boggy land; they are small tufted herbs with cottony heads due to the numerous hair-like bristles which take the place of the perianth and become much elongated in the fruiting stage.
The flowers are unisexual, and strikingly epigynous, theperianth and stamens being attached to a bell-shaped prolongation of the receptacle above the ovary.
The flower has in rare cases a perianth of six scale-like leaves arranged in two whorls, and thus conforming to the common monocotyledonous type of flower.

As to the perianth this view is supported by the existence of one species, the Iris falcifolia, the perianth of which consists of six equal parts.
The flowers of the blue flags have a perianth of six segments united below into a tube.
Heinricher however, in cultivating some anomalous forms of Iris pallida, succeeded in filling out this gap and in producing [174] flowers with a uniform perianth and six stamens, recalling thereby the supposed ancestral type.
The perianth is in six equal segments, and there are six stamens.
These plants, low as they rank in the vegetable world, have a regular perianth of six divisions with six stamens, and a three-celled capsule which opens by three valves.
This last appears the most natural arrangement, as all these plants have a regular perianth of six segments, with six stamens, and a dry or fleshy capsule of three cells, opening by as many valves.
The perianth of the flowers is, however, so small as to be inconspicuous.
Defn: A pouchlike portion of the perianth in certain orchides.
Defn: A genus of Old World amaryllideous bulbous plants, having a funnel-shaped perianth with six narrow spreading lobes.
Defn: Having the whole or part of the perianth petaline.
Coloured hairs are seen on the petals of Menyanthes, and on the segments of the perianth of Iris.
When the perianth (p) expands, the filaments are thrown out with force as at a, so as to scatter the pollen.
If the name is retained it ought properly to include only those parts which secrete a honey-like substance, as the glandular depression at the base of the perianth of the fritillary, or on the petal of Ranunculus (fig.
The diminished size of the perianth of cleistogamous flowers of such types as the violet is due directly to the action of diminished light upon the hidden or inclosed flower.
The growth of many leaves and of the perianth of flowers is hindered in diminished light.
They are (in the flowers) to be seen at a glance; within the spreading perianth there is a tubular crown or corona, having six lobes and a membranous fringe.
In the scilla there is no corona, neither a tube, but the petal-like sepals or divisions of the perianth are entire, going to the base of the flower.
Segments of the perianth united below into a narrow tube; leaves flat, smooth, dark green.
Flowers unisexual or perfect, the perianth of the male and female flowers dissimilar; stamens in two series, inserted on the corolla; filaments free; anthers introrse.
Segments of the perianth slightly united at the base.
Perianth deeply lobed; style narrowed gradually into a small oblique stigma; leaves green on both surfaces.
Limb, the dilated and usually spreading portion of a perianth or petal as distinct from the tubular part, or claw.
Its perianth is less than an inch long, and its staminodia are yellow, with inrolled edges.
The generic name, Zygadenus, is from the Greek, and signifies yoked glands, referring to the glands upon the base of the perianth segments.

The perianth is unilateral, 5 cleft, the two smaller segments, which are intermediate, being internal, or belonging to a different series.
T, metallic thermometer attached to the short arm of the upper lever; the specimen of Nymphaea, N, has one of its perianth leaves attached to the short arm of the second lever by a thread.
In Nymphaea it is the outer side of the perianth that is relatively the more excitable since diffuse electric stimulus induces a movement of opening due to the greater contraction of the outer side.
One of the perianth leaves was attached to one of the recording levers, the differential thermometer being attached to the other.
The diurnal record shows that the perianth leaves begin to open in the evening with falling temperature, and the flower becomes fully expanded by 10 p.
I find that the perianth leaves of this flower are markedly sensitive to variation of temperature.
Petals and perianth leaves, for example, bend outwards by day so as to open the flower, and inwards at night so as to close it.
For obtaining record all the perianth segments but one was removed.
The record given in figure 111 shows that the perianth segment, subjected to a few degrees' rise of temperature, responded by an up-movement of closure, due to greater expansion of the outer half.
The flower was tightly closed in the day time; and the perianth leaves began to open out in the evening at first slowly, then very rapidly, and the flower becoming fully expanded by 10 p.
Thus the inner side of the perianth leaves undergoes an expansion with rise of temperature attended by the opening of the flower; this movement of opening does not undergo any change on holding the flower in an inverted position.
The segments of the limb of the perianth are very unequal, the perianthtube is curved, funnel-shaped and widening upwards, the segments equalling or exceeding the tube in length.
Tulipeæ, tulip tribe; bulbous plants, with the segments of the perianth scarcely adherent in a tube.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "perianth" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: corona; flower; petal; pistil; receptacle; stamen; stigma; style
