Dipterocarpus geniculatus

Dipterocarpus geniculatus is a species of plant in the family Dipterocarpaceae. The species name is derived from Latin (geniculatus = with bent knee) and refers to the shape of the petiole. [1] There are two subspecies; D. geniculatus subsp. geniculatus and D. geniculatus subsp. grandis both of which are endemic to Borneo. Both subspecies are emergent tree, up to 60 m tall, in mixed dipterocarp forest. D. geniculatus subsp. geniculatus is found on leached sandy and sandy/silty clay soils and occurs in at least one protected area (Bako National Park). D. geniculatus subsp. grandis occurs on similar soils as well as those over ultrabasic rock and occurs in at least one protected area (Lambir Hills National Park).

<i>Drosera gigantea</i> Species of carnivorous plant

Drosera gigantea, the giant sundew, is an erect perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in sandy soils at the margins of swamps and near granite outcrops along the Western Australian coast from Albany north to just south of Geraldton. D. gigantea produces small shield-shaped leaves along many lateral branches that look like a small tree. Individual plants can grow up to 0.2–1 m (0.7–3.3 ft) tall. Because of its tall, tree-like form, it is considered one of the largest Drosera species. It is also easily cultivated and enjoys damp, humid conditions often provided in greenhouses. White flowers emerge from August to November. The red tubers of this species can grow to be 3.8 cm (1.5 in) in diameter and may be a metre below ground.
