- A
pulvinus (pl.
pulvini) may
refer to a joint-like
thickening at the base of a
plant leaf or
leaflet that
facilitates growth-independent movement. Pulvinus...
- four-sided and
attached singly to
small persistent peg-like
structures (
pulvini or sterigmata) on the branches, and by
their cones (without any protruding...
- with
nyctastic movements. Anatomically, the
movements are
mediated by
pulvini.
Pulvinus cells are
located at the base or apex of the
petiole and the...
-
leaflet to the leaflet's
swollen base (pulvinus), and from
there to the
pulvini of the
other leaflets,
which run
along the
length of the leaf's rachis...

Pulvini at both ends of the
petioles of
Elaeocarpus multiflorus...
-
portions of stem, are
flexible and
often pendent. The
stems are
rough with
pulvini that
persist after the
leaves fall. The
winter buds are
ovoid or globose...
-
mechanism for
leaves exists in the pulvinus.
Since flowers do not have
pulvini, the
movement is
caused by
increased growth rate of the stems. The growth...
- The
shoots are pale buff-brown,
glabrous (hairless) but with
prominent pulvini. The
leaves are needle-like, 15–20 mm long, 2 mm broad,
flattened in cross-section...
- buff-brown,
almost white, and
glabrous (hairless), but with
prominent pulvini. The
leaves are stiff, sharp, and needle-like, 15–25 millimeters long,...
-
considered to be turgor-mediated heliotropism. For
plant organs that lack
pulvini,
heliotropism can
occur through irreversible cell
expansion producing particular...
