Passages:
Scaevola coriacea, the dwarf naupaka, is a species of flowering plant in the "Goodenia" family, Goodeniaceae, that is endemic to Hawaii. Scaevola oxyclona, commonly known as Tangled Fanflower, is a spiny shrub in the family Goodeniaceae, native to Western Australia.  It grows to between 0.1 and 1.5 metres high and produces blue to purple flowers from August to December in its native range.  The species was formally described by Victorian Government Botanist Ferdinand von Mueller in the tenth volume of "Fragmenta Phytographiae Australiae" based on plant material collected at Frasers Range and Mount Benjamin. Scaevola albida, known by the common name of White Fan-flower, is a prostrate shrub found growing "from south-eastern Queensland through eastern New South Wales and coastal areas of Victoria and Tasmania in a range of habitats".  Unlike most other species of "Scaevola" which grow into a bush, "Scaevola albida" is a ground cover, forming a mat on the ground around 30-40 centimetres across.  Its leaves are bright green, semi-succulent and slightly hairy.  They are of an elliptical shape with wavy edges. <P2-S0> Scaevola hookeri, the creeping fan-flower or alpine fan-flower, is a prostrate perennial herb in the family Goodeniaceae. <P2-S1>  It is native to eastern Australia. <P2-S2>  Leaves are 6 to 50 mm long and 2 to 15 mm wide. <P2-S3>  Flowers are white or blue with a yellowish throat and appear between December and March in the species native range. <P2-S4>  The species was first formally described by W.H. de Vriese in 1850 in "Nederlandsch Kruidkundig Archief" and given the name "Merkusia hookeri". <P2-S5>  The species was transferred to the genus "Scaevola" in 1856. <P2-S6>  It occurs in grassland and woodland in high altitude areas in Victoria, New South Wales, Tasmania, and also South Australia where it is listed as "endangered". Scaevola is a genus of flowering plants in the "Goodenia" family, Goodeniaceae.  It consists of more than 130 tropical species, with the center of diversity being Australia and Polynesia. Goodeniaceae is a family of flowering plants in the order Asterales.  It contains about 404 species in twelve genera.  The family is distributed mostly in Australia, except for the genus "Scaevola", which is pantropical.  Its species are found across most of Australia, being especially common in arid and semi-arid climates. <P3-S0> Sonerila janakiana is a species of plant in the Melastomataceae family. <P3-S1>  It is a tuberous, scapigerous and stoloniferous plant species. Sesbania tomentosa, commonly known as Oahu riverhemp and ʻ Ōhai, is an endangered species of flowering plant in the pea family, Fabaceae, that is endemic to the main Hawaiian Islands as well as Nihoa and Necker Island.  It inhabits low shrublands and, rarely, dry forests, at elevations from sea level to 2500 ft .  Associated native plant species include akiʻ aki ("Sporobolus virginicus"), ilima ("Sida fallax"), naupaka kahakai ("Scaevola taccada"), and pili ("Heteropogon contortus").  Off-road vehicles, wildfires, grazing, and alien species competition have destroyed their habitat on the main islands, but they are still quite common on Nihoa and Necker.  At least 2000 specimens grow on Nihoa, while there are far less on Necker. This is a list of "Scaevola" species. The genus Sonerila Roxb.  belongs to family Melastomaceae.  This genus is characterized by presence of three petals (along with the genera "Stussenia" & "Lithobium") as opposed to five in the other members of the family.  Most members of the genus prefer growing in shady habitats.  It is a large genus including about 175 species.
