The monocots have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds. Historically, this feature was used to contrast the monocots with the dicotyledons or dicots which typically have two cotyledons; however, modern research has shown that the dicots are paraphyletic. From a diagnostic point of view the number ...
The grass family includes most of the known C 4 species – around 5000. They are only found in subfamilies of the PACMAD clade. Major C 4 crops such as maize, sugarcane, sorghum and pearl millet belong in this family. The only known species with C 3, C 4 and intermediate variants, Alloteropsis semialata, is a grass. [1] Aristida – 288 C 4 ...
Poaceae (/ p oʊ ˈ eɪ s i. iː,-s i aɪ / poh-AY-see-e(y)e), also called Gramineae (/ ɡ r ə ˈ m ɪ n i. iː,-n i aɪ / grə-MIN-ee-e(y)e), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated ...
The distinctive fruit, a multiple fruit that resembles an immature orange, is roughly spherical, bumpy, 8 to 15 centimetres (3–6 in) in diameter, and turns bright yellow-green in the fall. [5] The fruit excretes a sticky white latex when cut or damaged. Despite the name "Osage orange", [6] it is not related to the orange. [7]
Aside from cotyledon number, other broad differences have been noted between monocots and dicots, although these have proven to be differences primarily between monocots and eudicots. Many early-diverging dicot groups have monocot characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen. [5]
[7] [9] [13] [14] Ammophila arenaria built foredunes (the dunes closest to the beach) that are typically about 14 feet (4.3 m) high, which is much higher than the dunes associated with the native dune grass species Leymus mollis. [15] In the 1930s, A. breviligulata was introduced to about 3,000 acres (1,200 ha) on the Clatsop Peninsula in Oregon.
Uniola paniculata, also known as sea oats, seaside oats, araña, and arroz de costa, [1] is a tall subtropical grass that is an important component of coastal sand dune and beach plant communities in the southeastern United States, eastern Mexico and some Caribbean islands. Its large seed heads that turn golden brown in late summer give the ...
The Cyperaceae (/ ˌ s aɪ p ə ˈ r eɪ s i. iː,-ˌ aɪ /) are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large; botanists have described some 5,500 known species in about 90 genera [3] [4] – the largest being the "true sedges" (genus Carex), [5] [6] with over 2,000 species.
