Used as a house decoration at Tuguegarao, where it is very common. Plant 
usually scandent, growing on rocks in river-beds, or in sandy soil near streams. 
The identity of Rotula aquatica and Rhabdia lycioides was stated by Clarke, 0 
but without comment. Loureiro’s names are the older, both for the species and 
genus, the genus is considered to be monotypic, and the name Rotala in the 
Lythraceae, the only obstacle, is sufficiently distinct. If Rhabdia were retained, 
a new combination would be necessary. In order to finally settle the ques- 
tion, information was sought from Dr. A. B. Rendle, of the British Museum 
of Natural History, where Loureiro’s collections are preserved. He writes : 
“Loureiro’s type of Rotula aquatica consists mostly of leafless twigs but there are 
fragments of flowers fruits and leaves which put beyond doubt the identity of 
the plant with Rhabdia lycioides. An anatomical examination of the twigs con- 
firms the identity. As you suggest in your letter the name Rotula must be taken 
for the genus.” 
Tropics of both hemispheres.
