Pandanus glaucocephalus is a species of plant in the family Pandanaceae, endemic to Mauritius.
A low (6-8m), branching tree. The 20 cm-wide trunk is grey, and bears only a few stilt-roots (or none at all), near the base of the stem. The leaves are slender and pale green. Leaf margins are lined with very tiny pale, yellow-brown spines. The leaf midrib also has spines, but not near the base. In its shape and growth form, this species most resembles the related Pandanus barkleyi .
This species is most easily distinguished by its 17–20 cm, globose, glaucous, blue-grey fruit-head. This is born on a short, fat stem, with long, slender, leaf-like bracts that extend further than the fruit-head. Each fruit-head holds 35-45 compressed or irregularly angled drupes. The drupes' exposed parts are raised and conical, with flattened or depressed tips, covered in cracks and scattered stigmas. [1] [2] [3]
The Pandanus glaucocephalus is endemic to Mauritius, and grows in exposed, isolated patches in the highlands. It sometimes spreads vegetatively, rather than through seed. The leaf tufts can cause longer branches to break off and root on the ground where they fall. This can lead to large clumps forming. [4]
Pandanus is a genus of monocots with some 578 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. The greatest number of species are found in Madagascar and Malaysia. Common names include pandan, screw palm and screw pine. They are classified in the order Pandanales, family Pandanaceae.
Pandanus utilis, the common screwpine is, despite its name, a monocot and not a pine. It is native to Madagascar and naturalised in Mauritius and the Seychelles.
Roscheria is an endangered, monotypic genus of flowering plant in the palm family. The genus is named for Albrecht Roscher, a 19th-century German explorer, and the epithet for its single species R. melanochaetes derives from Latin and Greek meaning 'black' and 'bristle', alluding to the spines covering the trunks. They naturally occur on the Mahé and Silhouette Islands of Seychelles where they grow in mountainous rainforest and are threatened by habitat loss.
Pandanus microcarpus is a species of plant in the family Pandanaceae, endemic to Mauritius.
Pandanus palustris is a species of plant in the family Pandanaceae, endemic to Mauritius. It was once common in marshes and in the wetter highlands of Mauritius, but is now threatened by habitat loss.
Pandanus pyramidalis is a species of plant in the family Pandanaceae, endemic to Mauritius.
Drypetes deplanchei is a tree of eastern and northern Australia. It also occurs in New Caledonia and Lord Howe Island. The genus is derived from the Greek, dryppa meaning "olive fruit". The species named after Dr. Emile Deplanche, who collected this plant at New Caledonia. Common names include yellow tulip, grey boxwood, white myrtle, grey bark and yellow tulipwood.
