In this article we will discuss about the morphology of equisetum with the help of a suitable diagram. Equisetum, with some 15 or more species, is distributed all over the world except in Australia and New Zealand. It is commonly known as 'horse-tail' or 'scouring rushes'. The most conspicuous features of the plant are jointed nature of stems (Fig. 9.1 [...]
In this article we will discuss about the process of reproduction in equisetum with the help of diagrams. The cones (Fig. 9.3A) are terminal either on the main shoot as in E. arvense (Fig. 9.1 A, B), or on smaller lateral branches as in E. heymale. At the base of cone is a ring-like structure, the annulus or collar, formed [...]
In this article we will discuss about the anatomy of equisetum with the help of diagrams. Apical growth in rhizome and aerial stems is initiated by a pronounced pyramidal apical cell (Fig. 9. 1E) with three-cutting faces that are directed downwards. The apical cell cuts off cells in a continuous sequence to establish three tissue regions. Stem anatomy of Equisetum [...]
