Question: Which plant is found on an island, Andersonia or Baptisia? 

Context paragraphs:
Baptisia australis: Baptisia australis, commonly known as blue wild indigo or blue false indigo, is a flowering plant in the family Fabaceae (legumes).  It is toxic.  It is native to much of central and eastern North America and is particularly common in the Midwest, but it has also been introduced well beyond its natural range.  Naturally it can be found growing wild at the borders of woods, along streams or in open meadows.  It often has difficulty seeding itself in its native areas due to parasitic weevils that enter the seed pods, making the number of viable seeds very low.

Pathfinder Nuclear Generating Station: The Pathfinder Atomic Power Plant was a nuclear power plant built by Northern States Power Company.  It was located just northeast of Sioux Falls, South Dakota, and west of its suburb of Brandon.  It was named for the 19th century explorer John C. "Pathfinder" Fremont and was constructed in the mid-1960s in partnership with a group of other investor-owned utilities.  The main goal of this facility was to be a 'proof of concept' plant to gain practical experience in operating a nuclear plant.  Some of the other participating utilities would also go on to build their own plants.  Although the superheater developed by Allis-Chalmers was plagued with technical difficulties and which led to NSP's eventual decision to retire the reactor by 1967 (and convert the plant to run on gas and oil by 1968), the lessons NSP learned from Pathfinder served the company in its operation of the Prairie Island and Monticello nuclear plants.  The longest Pathfinder ever ran at its full rated power was 30 minutes, and it was only then the company found the flaws that led to the decision to retire the reactor.  After sitting idle for 23 years, the reactor vessel was removed from the plant in 1990 and transported to a low-level radioactive material dump in Washington.

Stylidium tenerrimum: Stylidium tenerrimum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).  It is an erect annual plant that grows from 4 to 30 cm tall.  Linear, oblanceolate, or deltate leaves, about 5-24 per plant, are scattered along the stems.  The leaves are generally 1.2-4.8 mm long and 0.3-0.8 mm wide.  This species lacks a scape but has cymose inflorescences that are 4-11 cm long.  Flowers are white and red.  "S. tenerrimum" is found around Darwin in the Northern Territory of Australia and the Victoria River, though it hasn't been recollected there since the type location was chosen.  Its typical habitat is sandy soils that remain moist, associated with grasses and sedges.  It flowers in the southern hemisphere from April to August.  "S. tenerrimum" is most closely related to "S. alsinoides", though it differs by its asymmetrical petals.  In his revision of the subgenus "Andersonia" in 2000, A.R. Bean placed "S. evolutum" into synonymy and noted that the type specimen of "S. mitrasacmoides" was not located and thus the application of this synonym is not certain.  Tony Bean assessed this species' conservation status as data deficient in 2000.

Stylidium nominatum: Stylidium nominatum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).  It is an annual plant that grows from 4 to 15 cm tall.  The oblanceolate leaves, about 5-15 per plant, form basal rosettes around the stem and are 2.5-9 mm long, 0.5-1.5 mm wide.  About 4-11 leaves per plant are also scattered along the stem and are generally 2.3-4.7 mm long and 0.3-0.5 mm wide.  Scapes are absent.  Inflorescences are 2-6 cm long and produce white flowers that bloom from April to June in the southern hemisphere.  "S. nominatum" is endemic to the northern area of Kakadu National Park and Melville Island in the Northern Territory.  Its habitat is recorded as being sandy soils in "Melaleuca viridiflora" woodlands, bases of sandstone escarpments, and gravelly yellow soil in flat, treeless areas.  "S. nominatum" is most closely related to "S. capillare".  In his recent revision of the subgenus "Andersonia", A. R. Bean noted that there is a large variation recorded in the specimens of this species and more work would need to be done to determine if there's more than one taxon involved with this species.  Further evaluation may reveal additional species.

Andersonia (plant): Andersonia is a genus of small evergreen shrubs in the family Ericaceae.  The genus is endemic to the Southwest Botanical Province in Western Australia.

Hesperelaea: Hesperelaea is a plant genus with only one species, probably now extinct.  Hesperelaea palmeri was found only on Guadalupe Island, a small island in the Pacific Ocean, part of the Mexican state of Baja California, about 400 km southwest of Ensenada.  The last collection of the plant on the island was in 1875, so the species and the genus must now be presumed extinct.  An intensive search for the plant in 2000 was unsuccessful.

Lysimachia venosa: Lysimachia venosa is a rare species of flowering plant in the family Primulaceae known by the common name veined yellow loosestrife.  It is endemic to Hawaii, where it is known only from the island of Kauai.  The plant was only collected twice, last in 1911, but in 1991, a branch was discovered that had broken off the steep cliffs above the headwaters of the Wailua River.  The branch was from a plant of this species and may have fallen from the summit of Mount Waialeale.  No more specimens have been found since and the plant may be extinct, but some experts believe it may still exist in unsurveyed parts of the habitat.  It was federally listed as an endangered species of the United States in 2010.

Pelargonium insularis: Pelargonium insularis is a species of plant in the Geraniaceae family.  It is endemic to the Samhah island in the Socotra Archipelago of Yemen.  It was discovered in 1999 on the north-facing limestone escarpment on the island.  It represents the first record of the genus from the Socotra Archipelago.  At the time of its discovery only a single plant was found and an extensive search failed to find more.  The cliffs in which it occurs are frequently enveloped in low cloud and provide a relatively moist refugium occupying less than 5 km2, on an otherwise desertic island.  Local informants know of the plant and comment that it is found along the cliffs and when fresh, provides incidental grazing for livestock.  Its natural habitat is rocky areas.  It is threatened by habitat loss.

Baptisia: Baptisia (wild indigo, false indigo) is a genus in the legume family, Fabaceae.  They are flowering herbaceous perennial plants with pea-like flowers, followed by pods, which are sometimes inflated.  They are native to woodland and grassland in eastern and southern North America.  The species most commonly found in cultivation is "B. australis".

Echium wildpretii subsp. trichosiphon: Echium wildpretii" subsp.  "trichosiphon is an "Echium" that is found high up in the area of La Caldera de Taburiente on the Canary Island of La Palma.  Like its sister plant on Tenerife, this plant forms a large rosette of silvery leaves which eventually give rise to tall spikes of bright pink flowers.  The plant is biennial and dies after flowering.  This plant can be grown in gardens, but requires good drainage and fairly mild conditions.  The plant hates water falling in the centre of the rosette and will often rot in such conditions.
