Question: Which of the Stangeria and Scindapsus flowering plants is found in more regions?
Context: Pterostylis rogersii, commonly known as the curled-tongue shell orchid, is a species of orchid endemic to the south-west of Western Australia.  As with similar orchids, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves but the flowering plants lack a rosette and have a single flower with leaves on the flowering spike.  This greenhood usually has a white and reddish-brown striped flower with a long, curved labellum and is found along the south coast between Binningup and Esperance. Stangeria eriopus is a cycad endemic to southern Africa It is the sole species in the genus Stangeria, most closely related to the Australian genus "Bowenia", with which it forms the family Stangeriaceae.  IUCN Red List Category & Criteria: Vulnerable, mainly due to habitat loss and over-exploiting for traditional medicine.  It is listed under CITES Appendix I / EU Annex A, and CITES prohibits international trade in specimens of this species except when the purpose of the import is not commercial, for instance for scientific research. Thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus.  Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.  This behavior occurs due to unilateral growth inhibition.  That is, the growth rate on the side of the stem which is being touched is slower than on the side opposite the touch.  The resultant growth pattern is to attach and sometimes curl around the object which is touching the plant.  However, flowering plants have also been observed to move or grow their sex organs toward a pollinator that lands on the flower, as in "Portulaca grandiflora." The Flora of the Australian Capital Territory are the plants that grow naturally in the Australian Capital Territory (ACT).  The environments range from Alpine area on the higher mountains, sclerophyll forest, to woodland.  Much of the ACT has been cleared for grazing, and is also burnt off by bushfires several times per century.  The kinds of plants can be grouped into vascular plants that includes gymnosperms, and flowering plants, ferns, bryophytes, lichens, fungi, and freshwater algae.  Four flowering plants are endemic to the ACT.  Also several lichens are unique to the ACT, however as further study is undertaken they are likely to be found elsewhere too. Alloschemone is a genus of flowering plants in the Araceae family that is native to the Amazon region of Bolivia and Brazil.  There are only two species in the genus and both are extremely rare.  These two species are "Alloschemone occidentalis" and "Alloschemone inopinata".  At one point in history, the genus "Alloschemone" was dissolved and added to "Scindapsus", but it has since been reinstated after further observations of the plants. Echinacea is a genus, or group of herbaceous flowering plants in the daisy family.  The "Echinacea" genus has nine species, which are commonly called purple coneflowers.  They are found only in eastern and central North America, where they are found growing in moist to dry prairies and open wooded areas.  They have large, showy heads of composite flowers, blooming from early to late summer.  The generic name is derived from the Greek word ἐχῖνος ("ekhinos"), meaning "hedgehog," due to the spiny central disk.  These flowering plants and their parts have different uses.  Some species are cultivated in gardens for their showy flowers.  "Echinacea purpurea" is used in folk medicine.  Two of the species, "E. tennesseensis" and "E. laevigata", are listed in the United States as endangered species. Epipremnum is a genus of flowering plants in the family Araceae, found in tropical forests from China, the Himalayas, and Southeast Asia to Australia the western Pacific.  They are evergreen perennial vines climbing with the aid of aerial roots.  They may be confused with other Monstereae such as "Rhaphidophora", "Scindapsus" and "Amydrium". Scindapsus is a genus of flowering plants in the Araceae family.  It is native to Southeast Asia, New Guinea, Queensland, and a few western Pacific islands. Monsteroideae is a subfamily of flowering plants in the Araceae family.  It contains genera including: "Alloschemone", "Amydrium", "Anadendrum", "Epipremnum", "Heteropsis", "Holochlamys", "Monstera", "Rhaphidophora", "Rhodospatha", "Scindapsus", "Spathiphyllum", and "Stenospermation".  The subfamily is notable for having many trichosclereids in the vegetative and floral parts of the plants, but rarely in the roots. Pterostylis scabra, commonly known as the green-veined shell orchid, is a species of orchid endemic to the south-west of Western Australia.  As with similar orchids, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves but the flowering plants lack a rosette and have a single flower with leaves on the flowering spike.  This greenhood has a white flower with green and pale brownish-fawn stripes and a long, curved protruding labellum.  It is found in inland areas between Kalbarri and Esperance.
Answer: Scindapsus
