| Extrorse anthers are somewhat concentrated in primitive dicots and primitive monocots and are rare in more advanced groups. |
|
| A wide range of monocots produce bulbs of modified leaves which store food over the winter. |
|
| The known flora consists of 41 ferns and fern allies, 3 gymnosperms, 291 monocots, and 516 dicots. |
|
| In monocots, calcium oxalate is most often laid down and usually as bundles of needle-shaped crystals known as raphides. |
|
| Ray's plant classification system was the first to divide flowering plants into monocots and dicots. |
|
| For example, thale cress and rice are model species for dicots and monocots, respectively. |
|
| Such herbaceous monocots are envisaged as evolving in the relatively uniform environment of the moist tropics. |
|
| In the monocots and a few paleoherbs, these crystalloids have a triangular shape, unlike all other flowering plants. |
|
| For herbaceous dicots and small woody shrubs we have used the same phenology as that for monocots. |
|
| Many proteins with similar properties have since been isolated from tobacco and other plant species, both dicots and monocots. |
|
| Because the blade of grass-type monocots elongate due to activity of the intercalary meristem at the blade base, the tip of the blade is more aged than the base. |
|
| Conifers resemble monocots rather than dicots in leaf development. |
|
| As with the number of floral parts, this character is not always reliable, as there are many monocots with reticulate venation, notably the aroids and Dioscoreales. |
|
| However, like palms and some members of the Iridales, they have plicate leaves, and these leaf forms are among the earliest known fossil monocots. |
|
| Water hyacinths, duckweed, and pondweed are all aquatic monocots. |
|
| Of the remaining taxa, 45 were monocots in seven families, and 111 were dicots in 39 families. |
|
| Lemnaceae, or duckweeds, are a family of monocots that thrive in eutrophic freshwater environments. |
|
| The loss of cambium is well illustrated in Houttuynia of the Saururaceae, although that genus is not ancestral to monocots. |
|
| Like most monocots, orchids generally have simple leaves with parallel veins, although some Vanilloideae have reticulate venation. |
|
| The orchid flower, like most flowers of monocots, has two whorls of sterile elements. |
|
|
|
| As is characteristic of monocots, all of the flower parts appear in multiples of three. |
|
| Are there monocots in which primary xylem and early metaxylem are vesselless but metaxylem contains vessels? |
|
| In the monocots, fibrillar appearances are common in end walls of tracheary elements of families with more numerous plesiomorphic features. |
|
| All large groups in angiosperms such as magnoliids, monocots, basal eudicots, rosids and asterids show a patchy image with both positive and negative observations. |
|
| Triclopyr is highly selective, it only affects actively photosynthesising dicots, leaving grass, and flowering monocots such as narcissus and bluebell bulbs, undamaged. |
|
| While progressively more is known about the secondary growth common to most vascular plants, the abnormal secondary thickening of monocots remains understudied. |
|
| Monocots comprise one-quarter of all flowering plant species, most of these are orchids, grasses, sedges, palms, and aroids. |
