Anatomy

Summary of stem anatomy (German)

Umriss rund oder oval. Leitbündel in einer Reihe. Epidermiszellen verholzt.

Description

Culm-diameter 1-2 mm, wall thin, radius of culm in relation to wall thickness approximately 1:0.25 or < 0.25. Outline circular wavy. Culm-center hollow and surrounded by a few thin-walled, not lignified cells. Epidermis-cells thick-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma in tangentially enlarged groups. Sclerenchyma in a large, peripheral continuous belt (> 3 cells). Cells medium thick-walled. Small sclerenchymatic sheath with 1-2 cells around vascular bundles. Largest vessels in vascular bundles in lateral position. Largest vessel in the bundle 20-50 μm. Cavities (intercellulars) between parenchyma-cells present, small, often triangular. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.

Checklist 2017 comments

Neues Taxon: Gegenüber SISF-2 neu aufgenommener Neophyt. Vermutlich durch Saatmischungen aus Nordamerika nach Mitteleuropa gelangt, ist die ruderale Art heute vielerorts etabliert, wird aber nicht immer klar von der sich ausbreitenden B. sitchensis getrennt.
