Hibiscus rosa-sinensis. Scarlet rose-mallow. 



Local names. — Gumamela (Guam); Tapuranga (Philippines); Kaute (Raro- 

 tonga); Aute (Samoa); Shoe-flower (India); Fu-sang (China). 



An ornamental shrub planted by the natives near their houses. In Guam only 

 the crimson-flowered varieties, single and double, are found. Leaves ovate, acumi- 

 nate, entire at the base, coarsely toothed at the apex, nearly glabrous; stipules 

 sword-shaped; peduncles axillary, as long as or longer than the adjoining leaf; 

 bracteoles 6 or 7, linear, half the length of the bell-shaped calyx; sepals lanceolate, 

 connate below the middle; staminal tube exceeding the corolla; capsule rounded; 

 many-seeded. Seldom seeds in cultivation. 



In India the flowers are used to black shoes, and paper colored with the petals is 

 used in the place of litmus for testing. The plant is easily propagated by cuttings. 

 These should be removed with a piece of the old wood adhering, placed in water 

 until roots begin to make their appearance, and then planted. In this way it is pos- 

 sible to have a fine hedge under way in a very short time, which begins to bloom 

 immediately if flowering twigs have been selected for cuttings,
