Growing over 10 meters high, [5] it can bloom at a height of around 25 cm. The slender, grooved stems are hairy bald to sparsely downy. The 5 to 6 cm long, triangular foliage leaves distributed on the stem are divided into a petiole and pinnate leaf blade. The petiole is (0.5 to) 1.5 to 3.5 cm long and the rachis is 0.4 to 2 cm long. The ...
Upper leaves are ovate or lanceolate, egg shaped to spear head shaped, and attach directly to the stem, sometimes with the base clasping and the shoulders of the leaf extended to be heart shaped. [4] The inflorescence is the upper 9 to 45 cm (3.5 to 17.5 in) of the stem. Each inflorescence has four to twelve groups of flowers with a pair of ...
Cotyledon from a Judas-tree (Cercis siliquastrum, a dicot) seedling Comparison of a monocot and dicot sprouting. 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 ...
The spermatophytes were traditionally divided into angiosperms, or flowering plants, and gymnosperms, which includes the gnetophytes, cycads, [5] ginkgo, and conifers. Older morphological studies believed in a close relationship between the gnetophytes and the angiosperms, [ 6 ] in particular based on vessel elements .
The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule ...
The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. 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 ...
In ferns and seed plants (including cycads, conifers, flowering plants, etc.) the sporophyte is the dominant generation; the obvious visible plant, whether a small herb or a large tree, is the sporophyte, and the gametophyte is very small. In bryophytes and ferns, the gametophytes are independent, free-living plants, while in seed plants, each ...
A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed] Dilleniales; superrosids consisting of Saxifragales and rosids (the APG IV system includes the Vitales in ...
