Common in waste places. The stems yield a good fiber. The natives make brooms, 

 with which they sweep their houses, of the stems of this and allied species, gathering 

 them afresh each morning. In the Philippines, according to Padre Blanco, poul- 

 tices are made by boiling the leaves and are applied to ulcers and other sores. In 

 India a tonic is made of the plant, which is said to be a good appetizer.

This species is said by Graudichaud to occur in Guam, where, according to his notes, 

 the natives call it "escobilla papagu," "papagu" meaning "poil si gratter" (hair 

 for scratching). It is given by Endlicher in his list of South Sea Island plants as 

 occurring in Guam," where it was collected by Lesson. According to Cavanille^'s 

 description, the species has ovate-lanceolate, serrate, tomentose leaves, axillary 1- 

 flowered very short pedicels, and five 2-beaked carpels. Calyx ciliate.

 I find not S. maura hnt S. mauritiana, which has the leaves " praesertim subtus
