Fontainea borealis is a small tree endemic to Papua New Guinea, in the family, Euphorbiaceae, which grows to a height of 12 m. [2]
Fontainea borealis is a small dioecious tree growing to 12 m. The colour of the stem exudate is unknown. New shoots have dense, antrorse (upward pointing) golden trichomes. There are no stipules and the leaves have petioles, which are swollen at both the base and apex. The upper surfaces of the leaves are dark-green and the lower surfaces, pale-green. There are 8-14 lateral veins on each side of the midrib and between these the venation is reticulate. This plant is very like Fontainea picrosperma , but differs in that it has no glands in the leaf lamina; the disk is irregularly lobed and not as high as that of F. picrosperma (c 0.6 mm high vs 0.7-1 mm); the calyx of the male flower has four lobes (versus 2-3 lobes); the male calyx lobes are ovate/broadly ovate versus triangular ovate; and the stamens are joined for 1–1.5 mm versus 0.5 mm for F. picrosperma .. [2]
Fontainea borealis is known only from the Eastern Highlands Province of Papua New Guinea, at altitudes of 1800-2000 m. [2]
The plant was first described by Paul Irwin Forster in "Three new species of Fontainea Heckel (Euphorbiaceae) from Australia and Papua New Guinea". [1] [2] The holotype K000959476 was collected in 1944 by L.S. Smith at Aiyura in the Central Highlands of Papua New Guinea. [3]
The specific epithet, borealis, derives from the Latin for "northern" and refers to the northerly distribution of this species with respect to the genus. [2]
Alstonia is a widespread genus of evergreen trees and shrubs, of the family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), professor of botany at Edinburgh from 1716-1760.
Aleurites is a small genus of arborescent flowering plants in the Euphorbiaceae, first described as a genus in 1776. It is native to China, the Indian Subcontinent, Southeast Asia, Papuasia, and Queensland. It is also reportedly naturalized on various islands as well as scattered locations in Africa, South America, and Florida.
Lawsonia inermis, also known as hina, the henna tree, the mignonette tree, and the Egyptian privet, is a flowering plant and the sole species of the genus Lawsonia. It is the source of the dye henna used to dye skin, hair and fingernails, as well as fabrics including silk, wool and leather. Medicinal properties for the cure of renal lithiases, jaundice, wound healing; prevent skin inflammation. The bark is traditionally used in treatment of jaundice and enlargement of the spleen, renal calculus, leprosy and obstinate skin diseases.

Androstachys johnsonii, the Lebombo ironwood, is a medium-sized Afrotropical tree species, and the sole member of the genus Androstachys in the Picrodendraceae. It is slow-growing, evergreen to deciduous, and dioecious, with flowers that are wind-pollinated. It is native to southeastern Africa and Madagascar, where it generally occurs gregariously on rocky hillsides, particularly in hot and dry situations. It produces a hard, durable wood which is of economic interest. Its specific name commemorates W. H. Johnson, a 19th-century Director of Agriculture in Mozambique. Four related species which are native to Madagascar, are usually placed in genus Stachyandra.
Nepenthes lamii is a tropical pitcher plant endemic to New Guinea, where it grows at an altitude of up to 3520 m above sea level, higher than any other Nepenthes species. Although once confused with N. vieillardii and previously regarded as conspecific with the closely related N. monticola, it is now recognised as a distinct species.
Nepenthes insignis is a tropical pitcher plant endemic to New Guinea and surrounding islands. The specific epithet insignis is Latin for "distinguished" or "remarkable".

It is cultivated over much of the temperate world as an ornamental plant, and is naturalised in some locations as an escapee from gardens. Plants are very often found under the synonym Stachys lanata or Stachys olympica.
