Question: Which genus has more species, Fir or Chelone?
Context: 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. Peucephyllum is a monotypic genus of flowering plants containing the single species Peucephyllum schottii.  Its common names include pygmy cedar, Schott's pygmy cedar, desert fir, and desert pine.  It is not a cedar, fir, or pine, but a member of the aster family, Asteraceae.  It is a leafy evergreen shrub with glandular, resinous foliage.  It flowers in yellow flower heads which have only disc florets.  The fruits are woody, bristly seeds with a pappus.  This plant is native to the deserts of Arizona, California, Nevada, and Utah in the United States and Baja California and Sonora in northern Mexico. Chelone is a genus of four species of perennial herbaceous plants native to eastern North America.  They all have similarly shaped flowers (which led to the name turtlehead due to their resemblance to the head of a turtle), which vary in color from white to red, purple or pink.  "C. cuthbertii", "C. glabra", and "C. lyonii" are diploid and "C. obliqua" is either tetraploid or hexaploid. 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". Abies milleri, an extinct species of fir known from fossil remains found in deposits from the early Eocene Ypresian stage (around 49.5 mya) in Washington State, USA, is the oldest confirmed record for the fir genus.  The species was described from 81 fossil specimens collected from Burke Museum site number A0307 in Ferry County, Washington.  The holotype specimen, number # "UWBM 31299", and the eleven paratype specimens are currently deposited in the collections of the Burke Museum in Seattle, where they were studied and described by Howard E. Schorn and Wesley C. Wehr.  Schorn and Wehr published their 1986 type description for "A. milleri" in the "Burke Museum Contributions in Anthropology and Natural History", Volume 1.  The specific epithet, "milleri", was coined in honor of Charles N. Miller Jr for his contributions to the study and understanding of the conifer family Pinaceae.  The studied specimens were excavated from the Tom Thumb Tuff member of the Klondike Mountain Formation in the city of Republic. Abies spectabilis (East Himalayan fir) is a conifer species in the family Pinaceae and the genus firs.  It is sometimes held to include the Bhutan fir ("A. densa") as a variety.  It is found in Afghanistan, China (Tibet), northern India, Nepal, and Pakistan.  It is a large tree, up to 50 m tall. Piloporia is a genus of two species of poroid fungi in the family Polyporaceae.  The genus was circumscribed by Finnish mycologist Tuomo Niemelä in 1982, with "P. sajanensis" as the type species.  The Indian species "P. indica" was added to the genus in 1988.  "P. sajanensis" is found in Asia and Europe.  In Asia, it is usually recorded on spruce, fir, and larch, while in Europe it is commonly found on spruce, but also on pine.  "Piloporia" species cause a white rot in conifers and hardwoods. Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses.  This genus was originally included in the related genus "Lycopodium", from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones.  The common name "firmoss", used for some of the north temperate species, refers to their superficial resemblance to branches of fir ("Abies"), a conifer.  In Australia, the epiphytic species are commonly known as tassel ferns. 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". Abies beshanzuensis (Baishanzu fir, Baishan fir) is a species of fir (genus "Abies") in the family Pinaceae.  It is endemic to Baishanzu Shan in southern Zhejiang province in eastern China, where it grows at 1850 m altitude and is threatened by collection and climate change.  The site is within the Fengyangshan – Baishanzu National Nature Reserve.  "Abies beshanzuensis" is classified as critically endangered by the IUCN Red List.
