Meanings of dicotyledons in anglès

We saw many tall graceful palms and tree ferns, but most of the trees were dicotyledons.

The plane of saponin passes from the liliaceæ and allied groups to the rosales and higher dicotyledons.

Angiosperms are again divided into the monocotyledons, as the palms, and dicotyledons, which include most European trees.

Such bases occur almost exclusively in the dicotyledons, generally in combination with malic, citric, tartaric or similar plant-acids.

Many of the dicotyledons look alike.

The parallel-veined leaves of monocotyledons have stems without distinction of wood, bark and pith; the netted-veined leaves of dicotyledons have exogenous stems.

Among this fossil wood Heer made out the cypress, the silver pine, the poplar, the birch, and some dicotyledons with caducous leaves.

In the dicotyledons root and shoot are represented as springing from the same point, and in monocotyledons from opposite poles in the seed.

In rarely or never becoming perfectly straight, these cotyledons differ remarkably from the ultimate condition of the arched hypocotyls or epicotyls of dicotyledons.

Still, to think that the monocotyledons evolved the familiar drupes, or stone fruits, on a parallel line to the dicotyledons is-amazing!

It is often assumed that monocotyledons are descended from some lower group of dicotyledons, probably allied to that which includes the buttercup family.

Many botanists divide the Phænogamia primarily into Gymnosperms and Angiosperms, and the latter into Dicotyledons and Monocotyledons.

All these points are common to Monocotyledons and Dicotyledons, and separate the Angiosperms collectively from all other plants.

Dicotyledons have bark, wood, and pith, and grow by producing a new ring of wood outside the old.

Amongst Dicotyledons the gamopetalous forms are admitted to be the highest development and a dominant one of our epoch.

The origin of the Monocotyledons and Dicotyledons remains one of the most difficult and attractive problems of Palaeobotany.)
