Are Fir and Asystasia both coniferous trees?
no
Fir
Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae.
 They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range.
 Firs are most closely related to the genus "Cedrus" (cedar).
 Douglas firs are not true firs, being of the genus "Pseudotsuga".
Asystasia
The genus Asystasia belongs to the family Acanthaceae and comprises approximately 70 species found in the tropics, including the weedy species "Asystasia gangetica".
Pseudotsuga
Pseudotsuga is a genus of evergreen coniferous trees in the family Pinaceae.
 Common names include Douglas fir, Douglas-fir, Douglas tree, and Oregon pine. "
Pseudotsuga menziesii" is widespread in western North America and is an important source of timber.
 The number of species has long been debated, but two in western North America and two to four in eastern Asia are commonly acknowledged.
 Nineteenth-century botanists had problems in classifying Douglas-firs, due to the species' similarity to various other conifers better known at the time; they have at times been classified in "Pinus", "Picea", "Abies", "Tsuga", and even "Sequoia".
 Because of their distinctive cones, Douglas-firs were finally placed in the new genus "Pseudotsuga" (meaning "false hemlock") by the French botanist Carrière in 1867.
 The genus name has also been hyphenated as "Pseudo-tsuga". Lactarius alnicola
Lactarius alnicola, commonly known as the golden milkcap, is a species of fungus in the Russulaceae family.
 The fruit bodies produced by the fungus are characterized by a sticky, vanilla-colored cap up to 20 cm wide with a mixture of yellow tones arranged in faint concentric bands.
 The stem is up to 5 cm long and has yellow-brown spots.
 When it is cut or injured, the mushroom oozes a white latex, which has an intensely peppery taste.
 The acrid taste of the fruit bodies renders them unpalatable.
 The fungus is found in the western United States and Mexico, where it grows in mycorrhizal associations with various coniferous trees species, such as spruce, pine and fir, and deciduous species such as oak and alder.
 It has also been collected in India.
 Two varieties have been named: var.
 "pitkinensis", known from Colorado, and var.
 "pungens", from Michigan. Arceuthobium abietinum
Arceuthobium abietinum is a species of dwarf mistletoe known as fir dwarf mistletoe.
 It is native to western North America from Washington to New Mexico to northern Mexico, where it lives in coniferous forests as a parasite on various species of fir, particularly white fir, giant fir, and red fir.
 This is a small shrub which is visible as a network of scaly yellowish stems extending above the bark of its host tree.
 Most of the mistletoe is located inside the host tree, attached to it via haustoria, which tap the tree for water and nutrients.
 The leaves of the mistletoe are reduced to knobby scales on its surface.
 It is dioecious, with male and female mistletoe plants producing spikes of staminate and pistillate flowers, respectively.
 The fruit is a sticky berry a few millimeters long which explodes to disperse the seeds it contains several meters away from the parent plant and its host tree. Jírova hill
Jírova hill (Czech: "Jírova hora" ) is a hill situated between the villages of Zbečník, Rokytník and Velký Dřevíč, approximately 1 km northwest from the centre of the town Hronov, Czech Republic.
 The eastern slope of the hill is very steep.
 The whole hill is covered mainly by coniferous forest (mainly spruce trees) and meadows.
 A deciduous forest grows on the southern slope, falling to Zbečník.
 A part of the forest on the top of the hill and the north slope is formed by young coniferous trees.
 A very small stream flows from the northern slope, from Rokytník to Velký Dřevíč.
 On the top of the hill there is a radio communications transmitter.
 In the western direction from the top of hill, construction of an artillery fort of the Czechoslovak border fortification system was planned prior to World War II. Cunninghamia
Cunninghamia is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae.
 They are native to China, northern Vietnam and Laos, and perhaps also Cambodia.
 They may reach 50 m in height.
 In vernacular use, it is most often known as "Cunninghamia", but is also sometimes called "China-fir" (though it is not a fir).
 The genus name "Cunninghamia" honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham. Abies amabilis
Abies amabilis, commonly known as the Pacific silver fir, is a fir native to the Pacific Northwest of North America, occurring in the Pacific Coast Ranges and the Cascade Range from the extreme southeast of Alaska, through western British Columbia, Washington and Oregon, to the extreme northwest of California.
 It is also commonly referred to as the white fir, red fir, lovely fir, Amabilis fir, Cascades fir, or silver fir.
 It grows at altitudes of sea level to 1500 m in the north of the range, and 1000 - in the south of the range, always in temperate rain forest with relatively high precipitation and cool, humid summers.
 Common associate trees are Douglas fir and in the extreme southern area of its range, California buckeye. Spruce-fir forests
Fir and spruce forests are greatly affected by slight fluctuations in climate.
 Temperature is the primary determinate for spatial patterns of fir and spruce.
 The two dominant trees in this type of forest are "Picea engelmannii" (Engelmann spruce) and "Abies lasiocarpa" (subalpine fir).
 Although thick-barked trees, such as the "Pinus resinosa", frequently survive fire, the thin bark of spruce make them more vulnerable.
 Trees such as the Douglas fir withstand much of the fire due to the thicker bark they have.
 The scale of the burn mosaic during a fire, relative to species niche requirements and mobility, can have major impacts on flora and fauna dynamics. Cinara confinis
Cinara confinis, the black stem aphid, is a species of aphid in the genus "Cinara", found feeding on the twigs of various species of fir ("Abies") and on several other species of coniferous trees.
 This aphid has a Holarctic distribution and is known from Europe, Asia, North America and Argentina.
