Moreover, the mode of development seems to be similar between exine and orbicular

The specimen comes from a remote swampy area on the north shore of Lake Superior about 45 km north of Marathon, Ontario, the only known occurrence of orbicular
when the design of four parts--such as Laval pipe section, rotatable outer shell, narrow orbicular
channel section, and gyrators section--is logical, it is suitable for the preparation of microencapsulated particles by RESS.
In general, trifoliate pinnules are composed of a main pinnule of various lengths to which are basally attached two symmetrically-placed, smaller, orbicular
pinnules, maximally 3 cm in length.
It is distinguished by swollen root-bearing nodes along the rhizomes, and the centrally peltate large orbicular

Normally, in September, scads of pale violet-colored blooms stand above the curvaceous, orbicular
blades and bloated petioles of water iris leaves.
The trunk vertebrae exhibit features characteristic of Rhinocheilus lecontei as enumerated by Hill (1971), namely flat zygosphenes in anterior view; obovate to oval prezygapophysial faces; thick neural spines (within the colubrines) that are also flat dorsally, overhanging centra posteriorly, with indented anterior and posterior edges; short centra, no epizygapophysial spines; depressed neural arches; round to slightly compressed cotyla; postzygapophysial faces that are obovate to orbicular
, strongly developed hemal keels and subcentral ridges, and swollen, very flat accessory processes.
Regarding shape, grass phytoliths are either unlobed (including orbicular
, square, rectangular and trapeziform shapes) or lobed (with sinuous margins).
the work curves of torques generated by blades were modeled taking into account the speed of resistance airflow, which appears when the blade moves in orbicular
