Discocactus hartmannii is a species of Discocactus found in Paraguay to Brazil [1]
Discocactus is a genus of tropical cacti. Discocactus plants are endemic to southern Brazil, eastern Bolivia, and northern Paraguay. These species are in the risk of extinction in the wild.
The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Around 80% of cactus species belong to this subfamily. The genera of the Cactoideae are characterized by microscopic foliage leaves. All photosynthesis occurs in shoot cortex cells covered by a persistent epidermis and stomata. Another important characteristic of this subfamily is ribbed stems, which enable the inner cortex to expand radially without breaking the shoot surface to absorb large quantities of water.
Ptychosperma is a genus of flowering plant in the family Arecaceae. Most are native to Australia and/or New Guinea, with a few in the Solomon Islands and in Maluku Province of eastern Indonesia. Some have been cultivated abroad as house or garden plants, and reportedly naturalized in certain regions.
Phillipsia is a genus of fungi in the family Sarcoscyphaceae. There are about 17 species in the genus, which collectively have a widespread distribution in subtropical and tropical areas. The genus was circumscribed by Miles Joseph Berkeley in 1881. The generic name honours Wales-born English botanist William Phillips (1822–1905).
Polykrikos is one of the genera of family Polykrikaceae that includes athecate pseudocolony-forming dinoflagellates. Polykrikos are characterized by a sophisticated ballistic apparatus, named the nematocyst-taeniocyst complex, which allows species to prey on a variety of organisms. Polykrikos have been found to regulate algal blooms as they feed on toxic dinoflagellates. However, there is also some data available on Polykrikos being toxic to fish.
Discocactus bahiensis is a species of Discocactus from Brazil.
Sarcochilus hartmannii, commonly known as the large boulder orchid', ravine orchid, Hartmann's sarcochilus or cliff orchid, is a lithophytic orchid endemic to eastern Australia. It forms spreading clumps with between four and ten thick, channelled leaves and up to twenty five white flowers with crimson spots near the centre.
Pultenaea hartmannii is a species of flowering plant in the family Fabaceae and is endemic to an area around the border between New South Wales and Queensland. It is an erect shrub with hairy stems, oblong to triangular leaves with the narrower end towards the base, and yellow flowers with red markings.
