In Calamites, Calamodendron, and Asterophyllites the scars of the branchlets or leaves are circular or oval, with only a single vascular scar, and situated inverticils at the top of well-marked nodes of the stem.
Fruit borne in verticilson the branches bearing transverse rows of rounded scars.
Fructification on spikes, with verticils of sporocarps.
When the outer surface is preserved it is sometimes seen to bear verticils of long needle-like leaves (C.
So in Saponaria, in Dianthus, and other Caryophylleæ, three and four verticils of stamens have been met with.
The cases referrible to this head may be ranged under two sections according as the increase is due to plurality of ordinarily single organs, or to an increase in the number of verticils or whorls.
Perhaps monocotyledonous plants are more subject to this numerical reduction of the parts of several verticils than are other flowering plants.
This suppression when confined to the parts of certain verticils makes the flower asymmetrical.
The parts of the several verticilsoften differ in their mode of aestivation.
Columella with twoverticils of three ascending branches, prolonged into a stout conical horn of twice the length.
Columella with twoverticils of three ascending lateral branches.
Radial tubes cylindrical, thorny, about as long as the thorny pyramidal tubes, armed in the distal half with four to eight verticils of short curved ciliae, and at the distal end with a similar small terminal verticil.
The single branches of the terminal verticils are here simple, whilst in the closely allied Auloceros they are forked or elegantly ramified (Pl.
The four spines of each group are divergent, six to eight times as long as the middle rod, each spine armed with three to four verticils of thorny branches.
Columella straight, with numerous (eight to twelve) triradiate verticils of ascending lateral branches, which are inserted in the shell-wall.
Apical horn cylindrical, twice as long as the shell, with eight verticils of teeth.
The pyriform three-jointed shell has neither lateral nor terminal free appendages, but possesses a very large apical horn, and an inner prolongation of this, an axial rod, which bears some triradiate verticils of branched spines.
Radial tubes verticillate, armed with a variable number of regularverticils of lateral branches.
Spines curved, three-sided prismatic, with six to nine verticils of three divergent branches, decreasing in size towards the distal end; the branches of the first verticil about twice as long as those of the fourth verticil.
Shanks straight, slender, pine-shaped, each in the distal half with three to four elegant verticils of thorny lateral branches.
At each nodal-point occurs one radial spine with six to eight verticils (spines in all one hundred to one hundred and twenty or more).
From each spine arise ten to twelve verticils of lateral branches; each verticil composed of three forked branches.
From each spine arise at equal distances (equal to the half radius of the cavity) fifteen to twenty verticils of branches which increase in size from the base of the spine.
The numerous verticils of the free distal part are of equal shape in all the spines, composed of three forked branches in the terminal, and of more ramified branches in the inferior parts.
Four main spines nearly as long as the shell diameter, three-sided prismatic, with four to six verticils of ramified lateral branches, each verticil composed of three forked branches, which ramify again.
At each nodal-point occurs one radial spine with twelve to sixteen verticils (altogether thirty to forty spines).
Shanks arborescent, pine-shaped, with four to six verticils of lateral branches, which again are ramified and thorny.
Each spine with eight to ten verticils of forked lateral branches, without spathillae.
From each spine arise at equal distances thirty to thirty-five verticils of branches, which decrease in size towards the distal end.
From their three leaf-shaped (often somewhat denticulated or spirally contorted) edges arise four verticils of lateral branches, each composed of three forked, thin branches.
The internal axial rod of the shell, which bears on its basal part three verticils of three diverging forked spines, x 300 Fig.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "verticils" in a variety of sentences. We hope that you will now be able to make sentences using this word.
