Anatomy
Summary of stem anatomy (German)
Umriss rund oder oval. Leitbündel in mehreren Reihen. Epidermiszellen verholzt. Chlorenchyma in tangential verlängerten Gruppen.Description
Culm-diameter 0.5-1 mm, center full, radius of culm in relation to wall thickness 1:1. Outline circular with a smooth surface. Culm-center full, containing unlignified cells. Epidermis- cells thin-walled all around. Large vascular bundles arranged in 2-3 peripheral rows. Chlorenchyma absent. 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. Distinct cavities (intercellulars) in the protoxylem area of vascular bundles.Distribution map
