Crassula natans | |
Crassula natans, commonly known as floating pigmyweed, [1] is a herb in the family Crassulaceae. [2]
The annual herb is often found in an aquatic environment. It blooms between July and November producing white-pink flowers. [2] The plant has decumbent filiform branches that are around 10 centimetres (3.9 in) in length and are often multi-branched when growing in marshy area, or slender floating branches up to 25 cm (9.8 in) in length. It has linear shaped leaves linear approximately 8 millimetres (0.31 in) long and 1 mm (0.039 in) wide in marsh plants, or for floating plants with a length of 14 mm (0.6 in) and a width of 2 mm (0.079 in). [3]
The plant is endemic to the wetlands of Cape Fold area of the Western Cape region of South Africa. [4] It has become naturalised in Western Australia where it is found in winter wet depressions and in gullies and lakes in the Great Southern, Wheatbelt, South West and Peel regions. [2] It is also found throughout southern South Australia, New South Wales and Victoria. [3]
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant. They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa.
Crassula helmsii, known as swamp stonecrop or New Zealand pigmyweed, is an aquatic or semiterrestrial species of succulent plant in the family Crassulaceae. Originally found in Australia and New Zealand, it has been introduced around the world. In the United Kingdom, this plant is one of five introduced invasive aquatic plants that were banned from sale from April 2014, the first ban of its kind in the country. It is on the Global Biodiversity Information Facility's Global Register of Introduced and Invasive Species of eleven countries.
Crassula colorata, the dense pigmyweed or dense stonecrop, is an annual plant in the family Crassulaceae. The species is endemic to Australia, occurring in Western Australia, South Australia, New South Wales and Victoria.
Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. It is sometimes referred to as the money tree; however, Pachira aquatica also has this nickname.
Hakea linearis is a shrub or tree in the family Proteacea and is endemic to Western Australia. It has smooth branches, mostly linear leaves and white flowers.
Crassula alata is a herb in the family Crassulaceae. It is native to the Mediterranean basin and is now also found in southern Australia and New Zealand. The succulent annual herb typically grows to a height of 5 centimetres (2.0 in). It produces white flowers in the spring time between August and October in the southern hemisphere.
Crassula closiana is a herb in the family Crassulaceae that is native to Western Australia.
Crassula colligata is a herb in the family Crassulaceae that is native to Western Australia.
Crassula decumbens, commonly known as rufous stonecrop, cape crassula or spreading crassula, is a herb in the family Crassulaceae that is native to southern parts of Australia, South Africa, and Chile. There are generally two accepted varieties: Crassula decumbens var. decumbens and C. decumbens var. brachyphylla.
Crassula exserta is a herb in the family Crassulaceae that is native to Western Australia.

Crassula atropurpurea is a succulent plant, very common and widespread in the southern Karoo regions of South Africa and Namibia.
Crassula biplanata is a succulent plant native to rocky ledges and mountainous areas in the southern parts of South Africa.
Wahlenbergia capensis, commonly known as the Cape bluebell, is a plant in the family Campanulaceae and is native to the Cape Province but has been introduced to Australia. It is an annual herb with up to four greenish blue, bell-shaped flowers with spreading petal lobes.
