This species lacks a scape. Inflorescences are 5–15 cm long and produce white flowers that bloom from April to September in Australia but occur year-round in Malesia. S. alsinoides's distribution ranges from northern Queensland in Australia north to the island of Luzon in the Philippines and southern parts of Sulawesi in New Guinea. In Australia its typical habitat has been reported as a sandy soil in swamps that are dominated by Melaleuca quinquenervia, but has also been found on creekbanks with Melaleuca leucadendra or in some of the wetter rock crevices. S. alsinoides is most closely related to S. fluminense.
Its conservation status has been assessed as data deficient.
