With the infloresence branched to such a degree It's unlikely to be L.ovata which has the infloresence in clumps. Open grassland habitat is way more typical of L.densiflora also (L.ovata is a plant of montane/subalpine run off lines & swamps).
Thanks @Tapirlord and @natureguy - useful tip about the branching of the inflorescence. Interesting see that both L. densiflora and L. ovata both occur at this site.
