Question: Are both Cylindropuntia and Aspen common names for certain tree species?
Context: Heritiera fomes is a species of mangrove tree in the family Malvaceae.  Its common names include sunder, sundri, jekanazo and pinlekanazo.  It is the dominant mangrove tree species of the Sundarbans of Bangladesh and India, and comprises about 70% of the trees in the area.  "H. fomes" is a major timber-producing tree.  It is threatened by over-harvesting, water diversions in the Ganges Basin, fluctuations in salinity due to upstream and coastal development and top dying disease.  The International Union for Conservation of Nature has assessed it as being "endangered". Acacia euthycarpa is a shrub or small tree species that is endemic to southern Australia.  It shares its common names of wallowa or reed-leaf wattle with a similar species "Acacia calamifolia".  It usually grows as a shrub to between 2 and 4 metres high, but certain forms may be small trees up to 10 metres high.  The linear phyllodes are up to 10 cm long, dull green or grey green and have sharply pointed hooked tips.  The globular golden flowerheads appear in 2-4 headed racemes between August and October, followed by curved seedpods that are up to 15 cm long. Populus tremuloides is a deciduous tree native to cooler mountainous areas of North America, one of several species referred to by the common name aspen.  It is commonly called quaking aspen, trembling aspen, American aspen, Quakies, mountain or golden aspen, trembling poplar, white poplar, popple, and even more names.  The trees have tall trunks, up to 25 meters (82 feet) tall, with smooth pale bark, scarred with black.  The glossy green leaves, dull beneath, become golden to yellow, rarely red, in autumn.  The species often propagates through its roots to form large clonal groves originating from a shared root system.  These roots are not rhizomes, as new growth develops from adventitious buds on the parent root system (the ortet). Pterospermum acerifolium (karnikara tree) is an angiosperm indigenous to Southeast Asia, from India to Burma.It is most likely to grow naturally along forested stream banks.  The best growing conditions are a seasonally moist then dry climate with access to full sunlight.  Pterospermum acerifolium is an angiosperm that is traditionally included in the Sterculiaceae family; however, it is grouped in the expanded Malvaceae family as well.  The classification "Pterospermum" is based on two Greek words, Pteron and Sperma, meaning “winged seed” and the species name acerifolium indicates leaves shaped like a maple's.  There is an array of common names for Pterospermum acerifolium, depending on the region where it is grown.  It is commonly referred to as Kanak Champa, Muchakunda or Karnikar Tree within its native range.  In the Philippines, it is known as Bayog.  Other common names include Bayur Tree, Maple-Leafed Bayur Tree, and Dinner Plate Tree.  It is a relatively a large tree, growing up to thirty meters tall.  Mostly planted as an ornamental or shade tree, the leaves, flowers, and wood of a Bayur Tree can serve a variety of functions. Cylindropuntia is a genus of cacti (family Cactaceae), containing the cholla, native to northern Mexico and the Southwestern United States.  They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Aspen is a common name for certain tree species; some, but not all, are classified by botanists in the section "Populus", of the "Populus" genus. Toxicodendron vernicifluum (formerly "Rhus verniciflua"), also known by the common name Chinese lacquer tree, is an Asian tree species of genus "Toxicodendron" (formerly "Rhus") native to China and the Indian subcontinent, and cultivated in regions of China, Korea and Japan.  Other common names include "Japanese lacquer tree", "Japanese sumac", and "varnish tree".  The trees are cultivated and tapped for their toxic sap, which is used as a highly durable lacquer to make Chinese, Japanese, and Korean lacquerware. Planchonia careya is a tree species in the family Lecythidaceae.  Common names include cocky apple, cockatoo apple and billygoat plum.  It produces an edible fruit which tastes like quince.  Indigenous Australians use the bark and leaves in medications.  The bark and roots were also used as a fish poison.  It should not be confused with "Terminalia ferdinandiana", with which it shares some common names. Prunus mume is an Asian tree species classified in the "Armeniaca" section of the genus "Prunus" subgenus "Prunus".  Its common names include Chinese plum and Japanese apricot.  The flower is usually called plum blossom.  This distinct tree species is related to both the plum and apricot trees.  Although generally referred to as a plum in English, it is more closely related to the apricot. The Janzen–Connell hypothesis is a widely accepted explanation for the maintenance of tree species biodiversity in tropical rainforests.  It was published independently in the early 1970s by Daniel Janzen and Joseph Connell.  According to their hypothesis, host-specific herbivores, pathogens, or other natural enemies (often referred to as predators) make the areas near a parent tree (the seed producing tree) inhospitable for the survival of seedlings.  These natural enemies are referred to as 'distance-responsive predators' if they kill seeds or seedlings near the parent tree, or 'density-dependent predators' if they kill seeds or seedlings where they are most abundant (which is typically near the parent tree).  Such predators can prevent any one species from dominating the landscape, because if that species is too common, there will be few safe places for its seedlings to survive.  However, because the predators are host-specific (also called specialists), they will not harm other tree species.  As a result, if a species becomes very rare, then more predator-free areas will become available, giving that species' seedlings a competitive advantage.  This negative feedback allows the tree species to coexist, and can be classified as a stabilizing mechanism.
