I have generally seen it in the marshy vegetation at the mouths 

 of the rivers. The flowers were always yellow or white. Accord- 

 in<^ to Thozet, the flowers are blue. Other collectors describe 

 them as whitish or pare white. The Philippine specimens referred 

 to by De CandoUe are rather more hairy (Bentham). 



158. Heliotropium indicum, L. A very common south Asiatic 

 weed which I have met with all through the Archipelago, but 

 which has not as yet extended to Australia. 



CON VOLVUL ACE^. 



159. Ipomcea bona-nox, L. A large twining convolvulus with 

 cordate leaves on a smooth stalk two or three inches long, with 

 large white salver-shaped flowers nearly five inches in diameter. 

 Common in the jungle and amongst shrubberies, along river-sides 

 all over India, Burmah, the Malay Archipelago and the Philip- 

 pines. I have heard one species called Ampas-ampas. 



160. Ipomcea quamoclit, L. This pretty little carmine- 

 flowered climber has been cultivated for ornament, but is now 

 established as a weed in the new and old worlds. It is believed 

 to be of Indian origin. 



161. Ipomcea reptans, Poir. A pi'ostrate floating species 

 found in wet, sandy places, or floating in water, in many parts of 

 tropical Asia and Africa. Corolla pink, purple or white, about 

 an inch and a half long. 



162. Ipomcea pes-capr^, Roth. On every strand in the tropics, 

 in Australia as far as New South Wales, and in every warm 

 climate of the new and old world. The leaves are on long 

 stalks and the flowers are purple. In Celebes it is called Batata- 

 pantei. The natives in every country where it grows have great 

 faith in the leaves employed as a poultice in rheumatic affections. 



163. Ipomcea batatas, L. Malay, Ubi, which is also applied 

 to the common potato ; Keledek is the common Malay name for 

 the sweet potato. The origin of this plant, universally cultivated
