Wollemia nobilis (Wollemi-pine) W.G.Jones, K.D.Hill & J.M.Allen 1995

critically endangered plant species in the araucariaceae family

Wollemia is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents one of only three living genera in the family, alongside Araucaria and Agathis (being more closely related to the latter). The genus has only a single known species, Wollemia nobilis, commonly known as the Wollemi pine (though it is not a true pine) which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges 150 km (93 mi) north-west of Sydney. The genus is

Corymbia citriodora (Lemon-scented-gum) (Hook.) K.D.Hill & L.A.S.Johnson 1995

Corymbia (Gum) K.D.Hill & L.A.S.Johnson 1995

plant genus in the myrtaceae family

Corymbia, commonly known as bloodwoods, is a genus of about one hundred species of tree that, along with Eucalyptus, Angophora and several smaller groups, are referred to as eucalypts. Until 1990, corymbias were included in the genus Eucalyptus and there is still considerable disagreement among botanists as to whether separating them is valid. As of January 2020, Corymbia is an accepted name at the Australian Plant Census.

Cycas micronesica (Cycad) K.D.Hill 1994

endangered plant species in the cycadaceae family

Cycas micronesica is a species of cycad found on the island of Yap in Micronesia, the Mariana islands of Guam and Rota, and The Republic of Palau. It is commonly known as federico nut or fadang in Chamorro. The species, previously lumped with Cycas rumphii and Cycas circinalis, was described as a unique species in 1994 by Ken Hill. Paleoecological studies have determined that Cycas micronesica has been present on the island of Guam for about 9,000 years. It has been implicated as a factor in Lytico-Bodig disease, a condition similar to amyotrophic lateral sclerosis (ALS), due to the presence

Cycas taitungensis (Cycad) C.F.Shen, K.D.Hill, C.H.Tsou & C.J.Chen 1994

endangered plant species in the cycadaceae family

Cycas revoluta (Sotetsu [Japanese ソテツ], sago cycad, sago palm, king sago, Japanese sago palm) is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant. The sago cycad can be distinguished by a thick coat of fibers on its trunk. The sago cycad is sometimes mistakenly thought to be a palm, although the only similarity between the two is that they look similar and both produce seeds.
