(After Allman.) logy as the monopodial or racemose, and the sympodial or cymose types respectively; each is characteristic of one of the two sub-orders of the Hydroidea, the Gymnoblastea and Calyptoblastea.
In the monopodial method (figs.
- Diagrams of the monopodial method of budding, shown in five stages (1-5).
- Trophosome without hydrothecae or gonothecae, with monopodial type of budding.
The polyps may be solitary, or form colonies, which may be of the spreading or encrusting type, or arborescent, and then always of monopodial growth and budding.
As in Gymnosperms, branching is monopodial; dichotomy or the forking of the growing point into two equivalent branches which replace the main stem, is absent both in the case able variety in form (see Leaf), but are generally small in comparison with the size of the plant; exceptions occur in some Monocotyledons, e.g.
The most striking characteristic of the majority of the Coniferales is the regular manner of the monopodial branching and the pyramidal shape.
