Each radial spine with three rows of verticillate lateral branches (a row arising from each edge of the spine).
From the dentated edges arise numerous verticillate branches, the proximal ends of which are thickly ramified.
These are very different in the two subgenera; in Hexancora each spine bears only three simple lateral branches, while in Hexapitys there are three rows of verticillate lateral branches on each spine.
In addition to these changes, which are those most commonly met with, the number of the parts of the flower is sometimes augmented, and a tendency to pass from the verticillate to the spiral arrangement manifested.
Defn: Arranged in a transverse whorl or whorls like the rays of a wheel; as, verticillate leaves of a plant; a verticillate shell.
Every other position of branches is only an alteration of the verticillate arrangement.
The verticillate position of the leaves is therefore the lowest, next succeeds the crucial, then the spiriform, and lastly the scattered.
This is most probably the case with the posterior odd or caudal tube, which seems to be never wanting, and in both families is developed in the form of a dichotomous brush (never in the form of a verticillate style).
Each of these is again forked, and each branch prolonged into a very long verticillate style.
The total number of long verticillate styles, which project over the outer surface of the fork-thicket, is eight in Coelotholus, whilst it is twelve in Coelothauma, and sixteen in Coelothamnus.
The length of the radial tubes is about twice as great as the radial diameter of the spongy framework, which forms the wall of the spherical shell, and is composed of thorny or verticillate cylindrical tubes.
There never occur in this family those characteristic "styles," or verticillate prolonged tubes, which we find in all Coelographida.
These latter differ also from the former in the constant possession of prominent verticillate styles.
In Gazelletta, the feet are usually armed with verticillate or alternate spines, which are either simple or branched (Pl.
Pinnate spines occur more rarely than verticillate ones; in this case the two paired lateral edges only of the prismatic spine bear opposite or alternate branches, whilst the odd middle edge bears no ramules.
The genus Auloceros differs from the preceding closely allied Aulographis, its ancestral form, in the ramification of the verticillate terminal branches.
Portion of a spike showing the verticillate arrangement of the branches and the glands; 2.
Besides these, there are in the Silurian and Erian beds plants with verticillate leaves which have been placed with the Annulariæ, but which may have differed from them in fructification.
As the branches increase in diameter the leaf-scars slightly enlarge and sometimes assume a verticillate appearance (Fig.
With regard to the verticillate type, we are at once reminded of Sphenophyllum (Fig.
The marshes themselves bristle thick with the deep green horse tail, Equisetum fluviatile, with its fluted stem and verticillate series of linear brandies.
Most of the species are North American herbs, having opposite, alternate, or verticillate leaves.
Small trees or shrubs, with opposite or verticillate petiolate leaves, interpetiolar stipules, and scaly buds.
Glabrous foetid or pungent aromatic trees, with fissured bark and verticillate or opposite spreading or drooping branches.
The pistillate flower--its constant nodal position and itsverticillate clusters.
Growth of wood and fruit emanating from the nodes; buds, branchlets and cones, therefore, in verticillate association.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "verticillate" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: corkscrew; helical; spiral; volute; whorled
