Dactylanthus Taylorii
''Dactylanthus taylorii'', commonly known in English as wood rose and in Māori as te pua o te rēinga, is a fully parasitic flowering plant, the only one endemic to New Zealand. The host tree responds to the presence of ''Dactylanthus'' by forming a burl-like structure that resembles a fluted wooden rose (hence the common name). When the flowers emerge on the forest floor, they are pollinated by a ground-foraging species of native bat. Description ''Dactylanthus taylorii'' is a round, warty, tuber-like stem (up to 50cm wide) or haustorium with no roots, which draws nutrients from the roots of its host. Its leaves do not photosynthesise, and are reduced to floral bracts. Some plants have been aged in excess of 30 years old. ''Dactylanthus'' prefers damp but not waterlogged soil, and is often found at the head of small streams. It parasitises about 30 species of native hardwood trees and shrubs, preferring those growing in secondary forest on the margin of mature podocarp forest ...

Hawaiian Baby Woodrose
''Argyreia nervosa'' is a perennial climbing vine native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa, and the Caribbean. Though it can be invasive, it is often prized for its aesthetic and medicinal value. Common names include Hawaiian baby woodrose, adhoguda अधोगुडा or vidhara विधारा (Sanskrit), elephant creeper and woolly morning glory. Its seeds are known for their powerful entheogenic properties, greater or similar to those of Ipomoea species, with users reporting significant psychedelic and spiritual experiences. The two botanical varieties are ''A. n.'' var. ''nervosa'' described here, and ''A. n.'' var. ''speciosa'', which are used in Ayurvedic medicine for their medicinal value. ''Argyreia nervosa'' seeds contain various ergoline alkaloids such as ergine. A study reported stereoisomers of ergine to be found in the seeds at a concentration of 0.325% of dry weight. A more recent study reported p ...

Rosa Gymnocarpa
''Rosa gymnocarpa'' is a species of rose native to western North America. It is known by the common names dwarf rose, baldhip rose, and wood rose. It grows in shady, damp, and rich forests. Description ''Rosa gymnocarpa'' is a perennial shrub growing up to in height. Its stem is covered with long, straight spines which may or may not be abundant. The pink or white fragrant flowers are flat and open-faced with five petals in most any shade of pink to almost lavender. Its fruit is a red rose hip containing hard tan achenes that contain the seeds. The sepals fall away from the hip earlier than in other species of rose, hence the name baldhip rose. The leaves are pinnately compound, alternate, with 5 to 9 leaflets, each of which are 1 to 4 cm. Leaflets are elliptic to ovate to round. See also * List of Rosa species There is significant disagreement over the number of true rose species. Some species are so similar that they could easily be considered variations of a single sp ...
