Neocallitropsis pancheri (Pancher Neocallitropsis) (Carrière) de Laub. 1972
endangered plant species in the cupressaceae family
Callitris pancheri is a plant species of the family Cupressaceae. It is endemic to New Caledonia, where it occurs in small, scattered population along rivers. It used to be placed in its own genus Neocallitropsis but molecular phylogenetic analysis indicated that it was nested within Callitris, but only when the New Caledonian species C. sulcata (to which it is most closely related) is included. It is an evergreen coniferous tree growing to 2–10 metres (7–33 ft) tall. The leaves are awl-shaped, 1 centimetre (0.4 in) long, arranged in eight rows in alternating whorls of four; in overall
Dacrycarpus dacrydioides (White-pine) (A.Rich.) de Laub. 1969
plant species in the podocarpaceae family
Dacrycarpus dacrydioides, commonly known as kahikatea (from Māori) and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of 60 metres (200 feet) over a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as Podocarpus dacrydioides, and was given its current binomial name Dacrycarpus dacrydioides in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera Dacrycarpus and Dacrydium. In
