The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. [3] The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two ...
The Atactostele stem, the long and linear leaves, the absence of secondary growth (see the biomechanics of living in the water), roots in groups instead of a single root branching (related to the nature of the substrate), including sympodial use, are consistent with a water source.
Leaves. Curio rowleyanus receives its common name from specialized leaves which are the size and shape of small peas (about 6 mm or 1 ⁄ 4 inch diameter).Its trailing stems can grow 2–3 feet (60–90 cm).

The visible part of the monocot plant (left) is actually the first true leaf produced from the meristem; the cotyledon itself remains within the seed Schematic of epigeal vs hypogeal germination Peanut seeds split in half, showing the embryos with cotyledons and primordial root Two ...
This striking succulent is known for how the light green, round, fleshy leaves stack beside each other. They look like small paddles or flapjacks, hence the plant’s common names.
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word succulent comes from the Latin word sucus, meaning "juice" or "sap". [1] Succulents may store water in various structures, such as leaves and stems.
3-D shape: Cylindrical with a circular or distorted circular cross-section and a single surface wrapping around it with no grooves or ridges. Subterete means the leaves are not completely terete, as seen in various lichens and succulents. trullate: whole leaf: Shaped like a masonry trowel: truncate: truncatus: leaf tip or base: With a squared ...
