Pandanus barkleyi is a species of plant in the family Pandanaceae, [1] endemic to Mauritius.
This is an extremely variable and difficult to identify species. Overall in its shape and growth form, this species can sometimes resemble the related Pandanus glaucocephalus .
Pandanus barkleyi is typically a short (4-5m) tree, with ascending branches. The 10–18 cm wide trunk is grey, fissured, and bears only a few stilt-roots near the base of the stem.
The leaves are slender and dark green, with a translucent light-yellow midrib. New leaves are initially erect, but they later droop, and eventually the old dead leaves persist hanging around the stem, beneath the dense rosette. The leaf margins are lined with very tiny yellow-green spines, but these are usually not near the leaf base.
This species has variable 9–18 cm, globose fruit-head that becomes greenish-brown to purple when ripe. Each fruit-head holds an extremely variable number (50-150) of drupes, which also vary in size, colour and shape. The drupes' exposed parts are often raised and conical, often covered in cracks and scattered stigmas. [2] [3] [4]
It is endemic to Mauritius, and dense clumps of it are quite common in the highlands, in marshes and on hill slopes. 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 and spreading outwards. The inside of the clump can die away, and the soil here is transformed into raised drier soil by the Pandanus. In this modified soil, other plants species develop and grow. [5]

Pandanus is a genus of monocots with some 750 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 Malesia. 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.
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.
Aloe purpurea is a species of Aloe endemic to the island of Mauritius, in the Indian Ocean, where it formerly occurred on dry rocky slopes and outcrops, the highland plateaus, and the forests of the west. It is part of a group of aloes which bear fleshy berries, and were therefore classed as a separate group, "Lomatophyllum". It is also one of only two Aloe species which naturally occur on Mauritius - both endemic and occurring nowhere else.
Roussea simplex is a woody climber of 4–6 m high, that is endemic to the mountain forest of Mauritius. It is the only species of the genus Roussea, which is assigned to the family Rousseaceae. It has opposing, entire, obovate, green leaves, with modest teeth towards the tip and mostly pentamerous, drooping flowers with yellowish recurved tepals, and a purse-shaped orange corolla with strongly recurved narrowly triangular lobes.
Rubus tricolor is an evergreen prostrate shrub, native to southwestern China. Leaves are dark green above, pale green below, and stems have red bristles. It has white flowers in summer, and edible red fruit. It grows approximately 0.3 m (1 ft) high and usually forming a vigorously spreading, dense mat. In cultivation it is mainly used as groundcover. Common names include Chinese bramble, groundcover bramble, creeping bramble, Korean raspberry, Himalayan bramble, Groundcover Raspberry. In Chinese it is called 三色莓.
