spinal column
The leaf area, number of green leaves, leaf opening rate, and rachis length were analysed.
Depending on the plant size, the three rachises together have 150 leaflets.

Examples of rachis

rachis
The trend in rachis length expansion was best described with a logistic function.
In contrast to the pinna rachis, the primary rachis is poorly preserved so that few anatomical features can be characterized.
Diameter of the leaf rachis was measured with calipers at the base of the leaf.
The apical plasma membrane of the rachis is elevated to form numerous microvilli-like projections into the lumen.
The main difficulty in indexing grains is that rachis internodes can be very short.
The rachis cytoplasm contains mitochondria, extensive rough endoplasmic reticulum, and electron-dense granules.
Each spermatocyte connects with the rachis in a narrow, waist-like constriction (fig. 7).
Small pinnules are alternately arranged along the rachis, attached at c. 45°.
Oocytes attached to the rachis have a large nucleus, and a cytoplasm rich in lipid droplets probably acting as a food reserve for further development.
The apical membrane of the rachis forms long microvilli-like projections with balloon-like tips.
For instance, asynchronous differentiation of rachis branch meristem from the primary inflorescence meristems is acropetal.
The first, fourteenth and fifteenth rachis node did not have 28 branches.
In contrast, asynchronous rachis branch development (acropetal differentiation of rachis branch meristems and/or spikelet meristems) progresses basipetally.
Asynchronous differentiation of spikelet meristems from a single rachis branch meristem is acropetal.
This bears dehiscent annulate sporangia on the rachis, the sporangia having uniseriate cell walls.
