 does not bloom continuously, but flowers in the month of November. The flowers 

 do not wither like many morning-glories, but remain open all day. The natives call 

 them "abubo," a different name from that applied to the plant itself. The children 

 string them on strings and sticks, and are very fond of them as ornaments. The 

 species is found in India and the Philippines. It has been introduced into the 

 Hawaiian Islands, where it has escaped from cultivation and established itself.
