A genus of trees with perigynous rosaceous flowers, and a single two-ovuled carpel which usually becomes a drupe in ripening.
When composed of one carpel a pistil is simple; when composed of several, it is compound.
This is seen in cases where the margins of the carpel do not unite, but remain separate, and consequently two placentas are formed in place of one.
The style proceeds from the summit of the carpel (fig.
Sometimes, however, as in Gramineae, the stigma of a single carpel divides.
As the placenta is formed on each margin of the carpel it is essentially double.
In the first-mentioned case the terms carpel and pistil are synonymous.
When a pistil consists of a single carpel it is simple or monocarpellary (fig.
The style of a single carpel, or of each carpel of a compound pistil, may also be divided.
When the pistil is formed by one carpel the inner margins unite and form usually a common marginal placenta, which may extend along the whole margin of the ovary as far as the base of the style (fig.
When in a compound pistil the style of each carpel is thus displaced, it appears as if the ovary were depressed in the centre, and the style rising from the depression in the midst of the carpels seems to come from the torus.
The carpel is sometimes stalked and often surrounded at the base by a honey-secreting disk; the style is terminal and in the zygomorphic flowers is often curved and somewhat flattened with a definite back and front.
Here each carpel is an open leaf, or with some introflexion, bearing ovules along its margins; and each placenta consists of the contiguous margins of two pistil-leaves grown together.

Defn: A genus of trees with perigynous rosaceous flowers, and a single two-ovuled carpel which usually becomes a drupe in ripening.

From the back of each carpel grows a wing, converting the fruit into two 1-seeded, at length separable samaras or keys.
Pistils coherent, forming a fleshy and rather woody cone-like red fruit; each carpel at maturity opening on the back, from which the 1 or 2 berry-like seeds hang by an extensile thread composed of unrolled spiral vessels.
Fruit ovoid to oblong, slightly flattened dorsally; carpel with 3 or 4 or all the ribs strongly winged; oil-tubes solitary in the intervals, 2 on the commissure.
The Tropaeolum has five petals, eight stamens, and three carpels, which are joined together into a trigonal fruit, each carpel containing one seed, which adheres to it.
There is only one seed in each carpel of the Nelumbium; and this seed, which has no thick leathery skin, is of about the size and shape of an acorn.
Each ovary contains only one ovule, and when the seed ripens, the carpel does not open to discharge it, but drops with the seed.
There are from sixteen to twenty carpels enclosed in the dilated receptacle, to which the stigmas form a ray-like cover; and each carpel contains several seeds.
At the base of each carpel is a kind of scale or gland, and this is the case with most of the genera included in the order.
The fruit, like the ovary, may be formed of a single carpelor of several.
In the former case they are either apocarpous, of one mature carpel or of several separate free carpels; or syncarpous, of several carpels, more or less completely united.
Occasionally a double fruit is produced, not by the incorporation of two flowers, but by the abnormal development of a second carpel in the flower.
The follicle is a dry unilocular many-seeded fruit, formed from one carpel and dehiscing by the ventral suture.
It is the carpel that has become sarcocarp--acid sarcocarp.
There is but one carpel which forms a pod with two valves when ripe (Fig.
The flowers are reduced to a single stamen or carpel (Figs.
As already stated, the ovules, instead of being borne on open carpels, are enclosed in a cavity formed by a single closed carpel or several united carpels.
After fertilization the carpel enlarges to protect the seed, and becomes fleshy or woody, in the latter case a group of carpels forming the well-known cones of Pine or Fir.
In Gymnosperms the carpel takes the form of a leaf or bract, upon which the naked ovule lies open to actual contact with the pollen grain.
The line of opening of a carpel corresponding to its midrib.
The seed vessel of plants of the Pea family, composed of a solitary carpel normally dehiscent only by the ventral suture.
In those flowers in which some number is definitely established, it often happens that one set may be reduced in number, and this is usually the carpel set.
It is evident, therefore, that a pistil may consist of one carpel or several carpels, and that in the latter case the carpels may be more or less completely united.
As the seed advances it becomes more and more complex, and when we reach still higher plants further surrounding tissues are pressed into its service and it becomes enclosed in the carpel of the highest flowering plants.
A special protuberance of the carpel in flowering plants which catches the pollen grains.
Sometimes among living plants curious diseases cause the carpels to become foliar, and when this happens the diseased carpel reverts more or less to the supposed ancestral leaf-like condition.
Open leafycarpel of "green rose," with two deformed ovules.
Here the petals were increased in number and variously modified, the stamens also; while in the centre and at the top of the flower, conjoined at the base with some imperfect stamens, was a carpel open along its ovuliferous margins.
The number of ovules in each carpel of the superior row varies greatly, and they are often, but not always, inserted in two longitudinal ranks, as is constantly the case in the lower carpels.
There are on record instances wherein a leaf-bud has been placed in the axil of a more or less leaf-like carpel; while at other times a second imperfect carpel has been met with in the axil of the first.
Each carpelis marked by vertical ridges, generally nine in number, five of them (primary ridges) being more prominent than the four intermediate or secondary ridges.
If now the open mouth be placed close over the carpel, and moist air be breathed upon it, the corkscrew will partially uncoil, causing the pointer to turn; and as the carpel dries again the pointer will resume its former position.
