That is to say, it leaves it open for a critic to assert that the vessels which enter the sides of the labellum are lateral vessels of the petal and do not necessarily represent petaloid stamens.
This anomaly [in Habenaria] is so far of importance, as it throws some doubt on the view which I have taken of the labellum being always an organ compounded of one petal and two petaloid stamens.
Sometimes there may even be seen by the naked eye green longitudinal stripes of calyx-like structure alternating with bright yellow petaloid parts.
Briot remarks that the monophyllous bastard acacia is liable to petaloid alterations of its stamens, which deficiency may encroach upon its fertility and accordingly upon the purity of its offspring.
On the other hand double flowers are exceedingly rare in the wild state, and even a slight indication of a tendency towards doubling, the stray petaloid stamens, are only rarely observed growing wild.
But this extreme is never reached bypetaloid double flowers.
In spiral flowers the distinction into series is by no means easy, and usually there is a gradual passage from sepaloid through petaloid to staminal parts, as in the water-lily family, Nymphaeaceae (figs.
In Iris it is situated on a cleft on the back of the petaloid divisions of the style (fig.
Sometimes, as in Canna, one of the anther-lobes becomes abortive, and a petaloid appendage is produced.
Seeds numerous, rounded and wing-margined; petals 10, large and showy; outer filaments petaloid in n.
Stamens 5, on the corolla, or monadelphous with 5 petaloid staminodia.
Perianth of 3 ovate or heart-shaped petaloid scales, mostly on claws, and usually with as many alternating small bristles.
In many double flowers, owing to the excessive multiplication of petaloid stamens, the pistil is suppressed, in which cases it often happens that the flower is depressed in the centre, as in some garden varieties of Ranunculus.
In some of these double orchids it is, however, necessary not to confound a petaloid condition of the existing column with the development of usually suppressed stamens in a petaloid form.
In some cases, as in Crocus and Rhododendron, this is shown even more clearly by the existence of two perfect pollen-sacs or quarter-anthers, the remaining portions being petaloid and continuous with the dilated filament.
In the malformed flowers no pollen is formed, at least in the more complete states of the malformation, but the walls of the anther lobe become preternaturally enlarged, and petaloid in texture and appearance.
Now, in this case, the margins of the anther were coherent to form the cup, and the pollen was emitted along a line separating the polliniferous from the petaloid portion of the anther.
Among polysepalous plants petaloid sepals have been observed in Ranunculus auricomus, Rubus cæsius, &c.
In some of the cultivated varieties of Anemone and Ranunculus all the parts of the flower remain in their normal state, except the pistils, which latter assume a petaloid appearance.
The styles of Anemone are also much enlarged as the result of cultivation, and from their petaloid appearance resemble those of the Iris (Goethe).
Gynoecium of Iris, consisting of an inferior ovary o, and a style, with three petaloid segments s, bearing stigmas st.
For example: in the Berberis vulgaris, the young calicinal leaflets have less resemblance to the bracts than to the petals of the corolla, and hence they have received the name of petaloid sepals.
We hesitate, therefore, whether we must give the name of calyx or bracts to the three under leaflets which are visible beneath the petaloid envelope of the Anemone nemorosa, or wood anemone.
To cut the knot, and please all parties, our beautiful floral envelope has been denominated a petaloid perianth.
Within the outer ovarian wall there was a circle of five petaloid pistils, some showing the placentae and ovules intermixed with the pink and purplish petaloid expansions.
The petals of cucurbita were observed in one instance united along two of the corollal sinuses to the staminal column, alternating with the smaller stamina; the processes were produced upwards into petaloid appendages.
Within this petaloid perianth is a membranous one, together with a boat-shaped bracteolate body, entire.
The carpella three, alternate as they ought to be with the last series of stamina, and hence they are opposed to the larger and outer segments of the petaloid perianth, but this last point deserves further examination.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "petaloid" in a variety of sentences. We hope that you will now be able to make sentences using this word.
