Ectophloic siphonostele is a type of stele found in the stems of some vascular plants. It is characterized by an outer layer of sclerenchyma cells that surround the vascular tissue. This type of stele is found in some species of ferns and horsetails.
Osmunda and Equisetum are two genera of plants that possess ectophloic siphonosteles. These plants have stems that are composed of a central pith surrounded by a layer of vascular tissue, which is in turn surrounded by a layer of sclerenchyma cells. The vascular tissue consists of a series of discrete bundles that are arranged in a circular pattern around the pith.
Other plant species that possess ectophloic siphonosteles include some members of the fern genus Dicksonia and the maidenhair fern (Adiantum). However, these plants are not listed as options in the given question.
In contrast, Marsilea and Botrychium, which are listed as options in the question, do not possess ectophloic siphonosteles. Marsilea has a type of stele known as a protostele, while Botrychium has a dictyostele. Adiantum and Cucurbitaceae, which are also listed as options, do not possess ectophloic siphonosteles either.
Therefore, the correct answer to the question is option A, Osmunda and Equisetum. These plants are unique in possessing ectophloic siphonosteles, which are a type of stele that is characterized by an outer layer of sclerenchyma cells that surround the vascular tissue.
