This is quite near C. trigynum VILL. from which it is distinguishable only 

 in having much narrower petals. It should better be regarded as a variety 

 of the same species.

The occurrence of the species in the island is rather doubtful.

This is very near SteUaria nutans HEMSL. in Jourii. Linn. Soc. XXXIV. 

 p. 434, (Tibet Oriental : Tatsiu-Lou) ; but differs from it by its larger and 

 broader leaves, and also in having rough velvety hairs all over the plant.
