Calocedrus rupestris is a species of conifer recently discovered in highly eroded rocky limestone mountains in northern Vietnam and first described in 2004. [2] It also occurs in China. [1]

Calocedrus rupestris is a medium-sized tree growing up to about 25 meters tall, with a trunk up to 1.2 meters in diameter. Many of the specimens observed in the wild were estimated to be some 600 to 800 years old, on the basis of preliminary year-ring observations. [2]

It occurs together with other lime-adapted species in highly endemic relict coniferous forest. However, the ecological region extends from Vietnam into Laos and China. These limestone-based coniferous forests are both vulnerable and threatened, and although a reserve has been established, this species is listed as an endangered species. [1]

Cypress is a common name for various coniferous trees or shrubs of northern temperate regions that belong to the family Cupressaceae. The word cypress is derived from Old French cipres, which was imported from Latin cypressus, the latinisation of the Greek κυπάρισσος (kyparissos). Cypress trees are a large classification of conifers, encompassing the trees and shrubs from the cypress family (Cupressaceae) and many others with the word cypress in their common name. Many cypress trees have needle-like, evergreen foliage and acorn-like seed cones.

<i>Cycas multipinnata</i> Species of cycad

Cycas multipinnata, common name Royal Sago, is a species of cycad or Sago Palm in southwestern China and northern Vietnam. It is noteworthy for three things: First it is one of the tuberous species which some taxonomists segregate as the genus Epicycas. Secondly, it has the longest leaf stalks (petioles) of any Gymnosperm; up to 11.5 feet. Cultivated plants have had petioles as long as thirteen feet. The total length of the bipinnate frond can be up to 23 feet seven meters) The ultimate pinnules are Y-shaped. Thirdly, this very conspicuous plant escaped notice until 1994. Among Gymnosperms, these fronds are exceeded in mass only by Encephalartos laurentianus.
