The following genera are expected to occur in British Burma. 



Dichondra repens, tforst, found in Mts. beyond Ava by Wallich, belongs to a small 

 group of Convolvulacece, with a deeply 2-4-lobed ovary with basilar style, and a fruit 

 of 2-4 utricles ; it is a small creeping herb with cordate or reniform leaves, and 

 small solitary axillary flowers. It is a native of warm countries in the old and new 

 worlds.
