How can you tell the difference between a royal red maple and a crimson king tree?
Almost impossible. They are both cultivars of Acer platanoides, Norway maple. Royal Red was selected from a stand of Crimson King (sometimes refered to as 'Schwedleri Nigra') maples. Supposedly it has better coloring.- sometimes Crimson King can fade to green as the season goes on. In practice I can't tell the two apart, and consider them basically interchangeable. http://search.schultesgreenhouse.com/120...

What are good trees to plant along streets?
This is actually a fairly complicated question, and there’s a good article about this here. In addition to what Robert Lockwood said about tree maintenance, these are the factors I would consider:What’s your climate? It’s impossible to recommend trees without knowing where you are. Palm trees look great in Florida, but won’t do well in Buffalo, NY.Are you talking about a residential, suburban street or city streets? Light is a big factor. Will your trees be shaded by tall buildings? How much sun or shade will it get?How much water will it get? (See #1) Will someone be watering them regularly, at least the first few years? On city streets, young trees won’t survive without watering.How much space will the tree have above ground? Do you want it to grow up straight and narrow? Do you want it to look like a lollipop and provide some shade? For example, you probably don’t want a tree that will be super wide and get in the way of cars or foot traffic like a weeping willow, Salix alba.How much space will the tree have below ground. In the city, this will be limited, so you need trees that won’t get too large and have an overly large rootball. Constricted roots can kill the tree, and they can also buckle sidewalks.Depending on your climate (see #1) how salt-tolerant is the tree? In Montreal, urban trees will get a steady spray of salt from the salted/snowy streets. In Miami, trees have to cope with the salty sea spray.Is the tree where there is a lot of foot traffic? Then you would not want a tree that fruits and will drop heavy fruits that could hurt someone, like a Quince tree, which is small and pretty and lollipop-shaped, but has 2-pound fruits like rocks.Do you want the tree to flower and be ornamental?What’s the quality of the soil?Does your city have any rules about which trees are acceptable?So, it’s really impossible to answer this question without more information. But that said, depending on your climate, maples are popular in USDA zones 7 and colder, some flowering fruit trees that don’t bear fruit, palms are popular in hot climates, lilacs smell good, and dogwoods are very pretty small trees for mild climates.
Some plants can survive in areas where air pollution is high. Suggest ONE characteristic which Leaves of such?
increased expression of enzymes such as superoxide dismutase to deal with increased levels of sulphur dioxide? found this.. may be what you want Mitrovic, Miroslava. (2006). Differences in Norway maple leaf morphology and anatomy among polluted (Belgrade city parks) and unpolluted (Maljen Mt.) landscapes., 25(2), 126-137 havnt cited properly but you should be able to find Abstract: Norway maple (Acer platanoides L.) is often used for urban landscaping because it is considered to be tolerant to different ecological conditions. This study examined leaf anatomy and morphology, and leaf damage symptoms (using the light and SEM microscopy) of maple tree growing in three Belgrade city parks (high polluted sites: park "Hall Pioneer" and Botanical garden "Jevremovac" within City industrial zone, and low polluted Kalemegdan park), and control site (unpolluted) at Maljen Mt. during a two-year period. Microscopic measures included thickness of leaves, upper and lower epidermis, palisade and spongy mesophyll and stomatal density. Differences in leaf attributes varied significantly among sites. Leaves in parks within industrial zone were thicker (with changes most expressed by the thickening of palisade mesophyll), smaller, heavier and more voluminous from the control ones. Leaf damage were noted only in the urban zone, expressed in form of light to dark colour chloroses, and reddish-brown marginal necroses related to toxic effect of elevated concentrations of particulate matter, SO2, and Pb, Zn and Ni in city air. Damage ranged from lesions to the last stadium of necrosis of whole mesophyll. SEM microscopy indicated erosive damage of the cuticle and stomata. We concluded that the sensitivity to air pollution of A. platanoides leaves is related to its leaf structure, low leaf volume and large intercellular spaces. In the same time, the leaf structural change (due thickening of mesophyll and increasing of leaf volume) follows the course of developing xeromorphic adaptations to the stressful conditions of urban environment.
Norway Maple vs. Sugar Maple?
There are two ways I look at them to tell them apart, first is the leafs. If you look at them side by side, Norway maple (Acer platanoides) has shallower sinuses between the leaf lobes, whereas in Sugar maple (Acer saccharum) they are deeper and more pronounced. The other way is in the terminal buds. The bud at the end of a branch on Norway maple is sort-of 'sceptre' like. A large bud is at the end of the branch, with very small axillary buds nestled next to it. In Sugar maple, you have three, quite pointed buds at the end of the branch. The center one is the longest, but they are similar in size to one another. I prefer the bud I.D. to the leaf I.D. when possible. I hope that this helps
Distinguish between the terms..1. taxonomy, phylogeny 2. kingdom, species 3. phylum, divison?
1) Taxonomy is a more general term that refers to the science of classifying organisms, but doesn't specify on what criteria the classification is based; phylogeny is classification based on evolutionary relationships. 2) Both are levels (ranks) of classification with kingdom being broader and including various related species. 3) Both of these are also levels of classification, but refer to organisms of the same rank - phylum is the term generally used for animals while division is used for plants and fungi. 4) Both are ranks below the level of species and are written along with the genus and species epithet so that all three terms are used. A subspecies is generally used for naturally-occurring variations and varieties for those which are artificially cultivated for a specific trait, but there's not any real convention (series of rules) for this and some sources use them interchangeably. When writing the names out, a subspecies is written as the rest of the scientific name with the abbreviation spp., as in Asclepias tuberosa spp. interior where a varietal name of naturally occuring examples uses the abbreviation var., as in Acer rubrum var. trilobum and cultivated varieties (also called cultivars) are usually put into quotation marks as in Acer platanoides "Crimson King".
Are the types of trees in Canadian cities basically identical to the types of trees in US cities of a similar latitude?
Montreal takes great care of its trees, so it was quite easy finding documentation on what is currently on the island. (However, it's in French)http://ville.montreal.qc.ca/pls/...This document indicates that the top 5 species for trees on the street are:-Fraxinus pensylvanica (red ash)-Acer platanoides (Norway maple)-Acer saccharinum (silver maple)-Tilia cordata (small-leaved lime)-Gleditsia triacanthos (honey locust)Those are only for street trees which are planted both on the public and private grounds boarding the streets. There are different trees in parks and forests (more ash, more maple essentially, but different types).The city of Montreal is trying to move away from planting new Ash trees because we currently have an epidemic of emerald ash borer. And the red ash has usually been our more popular tree...
I need information on the maple tree?
you should search on wikipedia. Here is some Maple, common name for a small family of trees, widespread in the temperate areas of the northern hemisphere, and for its representative genus. The family, which contains 2 genera and about 113 species, is recognized by its opposite leaves and small, radially symmetrical flowers in loose clusters. The flowers often lack petals. The ovary (female flower part) consists of two fused carpels (egg-bearing structures), which mature into two winged fruits. Maples are widely grown as ornamentals and street trees for their foliage and autumn colors. The species most commonly grown are medium to large deciduous trees with lobed “maple-shaped” leaves, such as the one depicted on the Canadian flag. Commonly planted species are red maple, sugar maple, black maple, and Norway maple. All these are natives of North America and Europe. Many of the Asian species differ radically from their western relatives. Some are small trees or bushes, some are evergreen, and some have entire (unlobed) leaves. The box elder, a maple native to much of the United States, has compound leaves with three to five leaflets. In addition to their ornamental importance, maples are a source of good timber, especially sycamore maple, and of sugar or syrup, especially sugar maple. The other genus of the family contains two species that are found in China. Scientific classification: Maples make up the family Aceraceae. The representative genus is Acer. The red maple is classified as Acer rubrum, the sugar maple as Acer saccharum, and the black maple as Acer nigrum (sometimes Acer saccharum nigrum). The Norway maple is classified as Acer platanoides, the box elder as Acer negundo, and the sycarmore maple as Acer pseudoplatanus. The other genus in the family is Dipteronia.
What kind of trees make "helicopter" seeds?
There are many many species from forests all over the world which have evolved this technique for seed distribution. Other respondents have named Acer/Maple and one person mentioned Fraxinus/Ash. Both good examples but northern hemisphere and deciduous all. I know of several Australian trees which use similar methods. In particular the Argyrodendrons or Booyongs… Argyrodendron - Wikipedia. They have a seed with a single long propellor, unlike the paired ones that occur in maples, but otherwise extremely similar. Walking across the forest floor, it is easy to imagine that the trees are maples because of the seeds. Then there are Hakeas and Banksias and Casuarinas which have woody capsules which release a single seed from each valve with a black membrane attached, which catches the air, allowing the seed to spin around and move laterally away from the original tree to find a new place to grow. Very similar to the technique used by many pines and their relatives.
