Scott, "The Anatomical Characters presented by the Peduncleof Cycadaceae," Ann.
The evidence afforded by normal and abnormal flowers appears to be in favour of the following interpretation: The peduncle is a shoot bearing two or more carpels.
The occurrence of more than two ovules on one peduncle is by no means rare; a particularly striking example is described by Fujii, in which an unusually thick peduncle bearing several stalked ovules terminates in a scaly bud (fig.
The ordinary type of female flower has the form of a long, naked peduncle bearing a single ovule on either side of the apex (fig.
A peduncle on which a flower-cluster is raised is a Common peduncle.
Scape, a peduncle rising from the ground or near it, as in many Violets.
Two pairs of muscles, apparently connected with the peduncle and its limited movements, have been minutely described by Hancock as having one of their extremities attached to this organ.
The function of these muscles, according to the same authority, is not only that of erecting the shell; they serve also to attach the peduncle to the shell, and thus effect the steadying of it upon the peduncle.
The bract and pedicels of the umbel all spring from the extremity of a peduncle 1½in.
It can be recognized at once by the connate leaves that form the fascicle or by the remarkable stout curved peduncle of its cone.
With both species the long peduncle of the conelet becomes overgrown by the basal scales of the ripe cone, which appears to be sessile.
Articulation usually takes place between the peduncle and the branch, sometimes with the loss of a few basal scales which remain temporarily on the tree (ponderosa, palustris, etc.
A subtropical species, ranging from Guatemala to the northern border of Sinaloa in northern Mexico; remarkable for the length of the peduncle of the cone and for the prevalence of septal resin-ducts in the leaf.
In the drawing of Pepo oblongus of Lobel, Icones, 641, the character of the peduncle is clearly defined.
The species is easily recognized by its fine soft down, the pentagonal peduncle which supports the fruit broadening at the summit; the fruit is more or less covered with a glaucous efflorescence, and the flesh is somewhat musk-scented.
Fourthly: in the male Ibla the capitulum is so much atrophied that it does not enclose the thorax or mouth, but still an elongated support or peduncle is left.
H), lies in a plane at right angles to the sides of the capitulum, and almost in a line with the orifice leading into the sack; but the peduncleis often very irregular (fig.
The movements, however, of the four opercular valves are not at all more independent of the other valves, than in the other Pedunculated Cirripedes; and the peduncle is furnished with all its characteristic muscles.
The peduncle is short, not equalling the capitulum in length.
The pedunclevaries much in length in the same species: in L.
Peronii it is the calcareous scales on the peduncle which have actually disappeared.
This species, not being symmetrically attached to a coralline, the peduncle does not curve, as in most of the other species, towards the rostrum.
Valves and spines on the peduncle yellowish: basal angle of the terga, viewed internally, blunt, owing to the lower carinal margin being more protuberant than the scutal margin.
The membrane of thepeduncle is continuous with the yellow membrane coating the external surface of the cup; and this latter membrane is continuous with those delicate laminae which, in a calcified condition, form the layers of the cup itself.
The peduncle is often, but not in the individual represented, much constricted at the point where it passes through the skin of the female, and generally at several other points, especially towards the extremity (see fig.
The peduncle is broad and flat, perforated in the middle, to which are attached four broad foliaceous arms.
The peduncle is attached to a vesicle, in which the microscope reveals a glandular body, yellow when the light traverses it, but white when the light is only reflected on it.
From this body issue two branches, which proceed towards the peduncle or base of the brown body up to the button or head.
All that you say about changed position of the peduncle in bud, in flower, and in seed, is quite new to me, and reminds me of analogous cases with tendrils.
Muller: "Your diagram of the movements of the flower-peduncle of the Alisma is extremely curious.
The difference in the size of the cells on the calyx under the vexillum right down to the common peduncle is conspicuous.
This was, therefore, strictly analogous with those cases in which the peduncle is normally spiney.
The portion near the pedunclewas binary, while the distal extremity of the fruit was ternary.
It is also interesting as showing how the peduncle may become swollen, and at the same time how the woody deposit of the endocarp may, as if by compensation, be deficient.
Godron remarks that in habitually irregular flowers the apex of the peduncle is oblique, and hence the flowers are bent downwards or spread horizontally, but if the receptacle be quite flat and level then the flower is regular.
Possibly in some of these cases the absence of the usual swelling of the upper part of the peduncle may be connected with its increased length.
Racemes two, both sessile, or one sessile and the other pedicelled on a peduncle which is more or less sheathed by a proper spathe, divaricate or deflexed.
The inflorescence consists of five to fifteen or twenty spikes spreading in all directions, distant or crowded; peduncle varies from 1 to 4 inches.
The leaf-sheath embracing thepeduncle is longer than the lower sheaths.
The inflorescence is a panicle with short branches, 1 to 3 inches long, rachis is pubescent; peduncle is 2 to 4 inches long, pubescent.
The inflorescence consists of three to ten spikes springing from the top of a slender glabrous peduncle 2 to 6 inches long.
Olfactory fissure, over which the olfactory peduncle and lobe are situated.
Each peduncle joins, along with the taenia semicircularis, the anterior pillar of the fornix of its own side.
More externally the mesial fillet is seen, while dorsal to the cerebellar peduncle is the posterior longitudinal bundle.
If the section happens to pass through the superior corpus quadrigeminum a characteristic circular area appears between the cerebellar peduncle and the fillet, which, from its tint, is called the red nucleus.
The superior cerebellar peduncle is the most internal of these and decussates with its fellow of the opposite side so that the two tegmenta are continuous across the middle line.
The rectal peduncle or pedicle of invagination; its attachment to the ectoderm is coincident with the hindmost extremity of the elongated blastopore of fig.
To the right (in the figure) of the rectal peduncle is seen the deeply invaginated shell-gland ss, with a secretion sh protruding from it.
The anal opening forms at a late period by a very short ingrowth or proctodaeum coinciding with the blind termination of the rectal peduncle (fig.
The lower and naked part of the sub-peduncle (C) is likewise slightly sensitive to a rub, and I have seen it bent round a stick and even partly round a leaf with which it had come into contact.
The common peduncle (A) has not the power of clasping a support, nor has the corresponding part of a true tendril.
It consists of a peduncle (A), bearing two branches which diverge equally from it.
If we inquire how a petiole, a branch or flower-peduncle first became sensitive to a touch, and acquired the power of bending towards the touched side, we get no certain answer.
In the present plant the two lateral branches of the main flower-peduncle have been converted into a pair of tendrils, corresponding with the single "flower-tendril" of the common vine.
The main peduncle is thin, stiff, and from 3 to 4.
An adjoining peduncle described during the same time similar, though fewer, ellipses.
My son found one very young tendril surmounted by traces of floral organs, exactly like those on the summit of the true flower-peduncle at the same early age.
The increasing length of the sub-peduncle (C) with the decreasing number of the flower-buds is a good instance of the law of compensation.
The peduncle divides above, and each branch joins one of the calices of the same hemisphere.
In the Serpent melon, which has a narrow tortuous fruit above a yard in length, the stem of the plant, the peduncle of the female flower, and the middle lobe of the leaf, are all elongated in a remarkable manner.
Clusters small to medium, more or less compound, usually shouldered, compact; pedicels thick; peduncleshort to medium.
Clusters of small or medium size; peduncle medium in length.
A second umbel at the base of the peduncle occasionally occurs.
Umbels mostly more than one; peduncle not overtopping the leaves.
Inflorescence usually compound, of small axillary spiked or racemed or umbel-like clusters or cymes, or when reduced to a single flower the peduncle mostly 2-bracteate.
Fertile flowers solitary or several together on a peduncle at the end of the branches, with a 4-toothed calyx, bearing 4 small petals at the sinuses.
In Anelasma the peduncle becomes deeply buried in the flesh of the Shark, and its surface is covered with short branching, root-like filaments.
