Notes
In the precursor I have remarked under L. javanica (Lc. 106) that the species is very polymorphous. Still, I distinguished two other allied species, L. mollissima WALL. ex BTH. and L. flaccida R.BR., which differed mainly in the indument of the calyx, the relative length of the corolla tube, etc.
However, closer examination of descriptions and material has made it clear to me that these differences cannot be upheld, and that only one polymorphous, very widely distributed species is involved, the oldest name of which is L. flaccida R.BR.
Experimental and field work may show that here and there racial distinctions might be possible.
