Richard Lawrence Hoffman (September 25, 1927 – June 10, 2012) was an American zoologist known as an international expert on millipedes, and a leading authority on the natural history of Virginia and the Appalachian Mountains.
 He was a biology professor at Virginia's Radford College for almost thirty years, and curator of invertebrates at the Virginia Museum of Natural History for another twenty years.
 He co-founded the Virginia Natural History Society, described over 400 species of millipedes, and produced more than 480 scientific publications.
 He is commemorated in the scientific and/or common names of over 30 animal species, including the valley and ridge salamander ("Plethodon hoffmani") and Hoffman's dwarf centipede ("Nannarrup hoffmani").
Abies fraseri, the Fraser fir, is a species of fir native to the Appalachian Mountains of the Southeastern United States.
Balsam woolly adelgids (Adelges piceae) are small wingless insects that infest and kill firs, especially balsam fir and Fraser fir.
 They are an invasive species from Europe introduced to the United States around 1900.
Anthophylax attenuatus is the species of the Lepturinae subfamily in long-horned beetle family.
 This beetle is distributed in Canada, and USA.
 Adult beetle feeds on sugar maple, American beech, and on hophornbeam.
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.
Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States.
 It is a high elevation tree, typically occurring at 1400 - elevation, though only rarely reaching tree line.
 The name red fir derives from the bark color of old trees.
Abies cephalonica or Greek fir is a fir native to the mountains of Greece, primarily in the Peloponnesos and the island of Kefallonia, intergrading with the closely related Bulgarian fir further north in the Pindus mountains of northern Greece.
 It is a medium-size evergreen coniferous tree growing to 25 - – rarely 40 m – tall and with a trunk diameter of up to 1 m .
 It occurs at altitudes of 900 - , on mountains with a rainfall of over 1000 mm .
Anthophylax hoffmani is the species of the Lepturinae subfamily in long-horned beetle family.
 This beetle is distributed in United States.
 Adult beetle feeds on Fraser fir.
The Black Mountains are a mountain range in western North Carolina, in the southeastern United States.
 They are part of the Blue Ridge Province of the Southern Appalachian Mountains.
 The Blacks are the highest mountains in the Eastern United States.
 The range takes its name from the dark appearance of the red spruce and Fraser fir trees that form a spruce-fir forest on the upper slopes which contrasts with the brown (during winter) or lighter green (during the growing season) appearance of the deciduous trees at lower elevations.
 The Eastern Continental Divide, which runs along the eastern Blue Ridge crest, intersects the southern tip of the Black Mountain range.
Pseudotsuga menziesii, commonly known as Douglas fir or Douglas-fir, is an evergreen conifer species native to western North America.
 One variety, the coast Douglas fir, grows along the Pacific Ocean from central British Columbia south to central California.
 A second variety, the Rocky Mountain Douglas fir, grows in the Rocky Mountains from British Columbia south to Mexico.
 The tree is dominant in western Washington.
 It is extensively used for timber, worldwide.
