trimerous

For example, trimerous flowers and monosulcate pollen are also found in magnoliids.

They are characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves.

The zygomorphic, trimerous, nodding flowers grow singly and are terminal on the stems.

The flowers are actinomorphic, hypogynous, and usually trimerous.

The flowers are trimerous, radially symmetric.

The flowers are large and showy, bisexual, trimerous, actinomorphic (less often slightly zygomorphic, as in Sprekelia).

The flowers are usually trimerous; borne singly or in compound inflorescences; bisexual and rarely unisexual.

The showy white trimerous flowers are open in spring and are followed by capsules opening by three valves which contain the numerous black seeds.

Many early-diverging dicot groups have "monocot" characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen.

Some of the paleodicots share apparently plesiomorphic characters with monocots, e.g., scattered vascular bundles, trimerous flowers, and non-tricolpate pollen.

One of the most noticeable traits is that a monocot's flower is trimerous, with the flower parts in threes or in multiples of three-having three, six, or nine petals.

These plants are closely related to Trillium, with the distinction traditionally being that Trillium contains species which have trimerous (three-petaled) flowers, and Paris contains species which have 4- to 11-merous flowers.

Would you not consider as a morphological difference the trimerous, tetramerous, etc., divisions of flowers, the ovules being erect or suspended, their attachment being parietal or placental, and even the shape of the seed when of no service to the plant.

They differ from other related families by often being pachycauline (i.e. with a thickened trunk, usually wider at the base, which has a water storage function), by usually having succulent leaves, and by possessing a trimerous flower with a superior ovary and seeds with an aryl.
