Equisetum telmateia ssp. braunii (Milde) Hauke.
subg. Hippochaete
- Common Name: Great Horsetail
- Family: Equisetaceae Rich. ex DC
- Country of Origin: pacific coast of North America
- Description: [Syn. E. maximum Lam, E. eburneum Schreber ex Roth, E. macrostachyon Poiret, E. majus Garsault]
E. telmateia is the largest member of the subgenus Equisetum and in Europe the most southerly in range. Abnormalities occur relatively frequently in this species, such as vegetative stems bearing underdeveloped cones, aborted cones terminating branches, cones proliferating as vegetative stems, stems with spiral sheaths. Unfortunately, these have often been given taxonomic names.
In filled areas such as roadsides and railroad embankments, this may appear to be growing under xeric conditions, but probably the same is true here as with E. arvense, that the underground rhizome system is, at least in part, in saturated soil under the fill.
