George Duryea Hulst
George Duryea Hulst (9 March 1846 – 5 November 1900) was an American clergyman, botanist and entomologist. Biography He graduated from Rutgers University in 1866 and received a degree from New Brunswick Theological Seminary in 1869, finally receiving his degree of Doctor of Philosophy from Rutgers in 1891. He was the pastor at the South Bushwick Reformed Church in Brooklyn, New York, starting soon after his ordination in 1869, and continuing until his death in 1900. Although this was his main focus, he also managed to make substantial contributions to science during those same years. He was an early member in the Brooklyn Entomological Society, and he was editor of its publication '' Entomologia Americana'' from 1887 to 1889. In 1888, he took on the new position of entomologist at the Rutgers' New Jersey Agricultural Experiment station, founding the department of entomology there and teaching entomology courses at the university. He resigned after only a year when it becam ...

Tsuga Mertensiana
''Tsuga mertensiana'', known as mountain hemlock, is a species of hemlock native to the west coast of North America, found between Southcentral Alaska and south-central California.

Moths Described In 1896
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...

Thuja Plicata
''Thuja plicata'' is an evergreen coniferous tree in the cypress family Cupressaceae, native to western North America. Its common name is western redcedar (western red cedar in the UK), and it is also called Pacific redcedar, giant arborvitae, western arborvitae, just cedar, giant cedar, or shinglewood. It is not a true cedar of the genus ''Cedrus''. Description ''Thuja plicata'' is a large to very large tree, ranging up to tall and in trunk diameter. Trees growing in the open may have a crown that reaches the ground, whereas trees densely spaced together will exhibit a crown only at the top, where light can reach the leaves. The trunk swells at the base and has shallow roots. The bark is thin, gray-brown and fissured into vertical bands. As the tree ages, the top is damaged by wind and replaced by inferior branches. The species is long-lived; some trees can live well over a thousand years, with the oldest verified aged 1,460. The foliage forms flat sprays with scale-like ...

Larix Occidentalis
The western larch (''Larix occidentalis'') is a species of larch native to the mountains of western North America (Pacific Northwest, Inland Northwest); in Canada in southeastern British Columbia and southwestern Alberta, and in the United States in eastern Washington, eastern Oregon, northern Idaho, and western Montana. It is the most productive of the three species of larch native to North America. Description The tree is a large deciduous conifer reaching tall, with a trunk up to diameter; the bark ranges from orangish to purplish brown. The crown is narrow conic; the main branches are level to upswept, with the side branches often drooping. The shoots are dimorphic, with growth divided into long shoots (typically long) and bearing several buds, and short shoots only long with only a single bud. The leaves are needle-like, light green, long, soft and very slender; they turn bright yellow in the fall, leaving the pale orange-brown shoots bare until the next spring. The s ...

Pinus Contorta
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine zone, subalpine, but is rare in lowland temperate rainforest, rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The Crown (botany), crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches a ...

Pinus Monticola
Western white pine (''Pinus monticola''), also called silver pine and California mountain pine, is a species of pine in the family Pinaceae. It occurs in mountain ranges of northwestern North America. It is the List of U.S. state trees, state tree of Idaho. Description Western white pine is a large tree, regularly growing to tall. It is a member of the Pinus classification, white pine group, ''Pinus'' subgenus ''Strobus'', and like all members of that group, the leaves ('needles') are in Fascicle (botany), fascicles (bundles) of five, with a deciduous sheath. The needles are finely serrated, and long. The cones, appearing even on young trees, are long and slender, long and broad (closed), opening to broad; the scales are thin and flexible. The seeds are small, long, and have a long slender wing long. The branches are borne in regular Whorl (botany), whorls, produced at the rate of one a year; this is pronounced in narrow, stand-grown trees, while open specimens may have ...
