A new Clover-leaf Desmodium in Singapore?

I’m back in Bidadari Cemetery to finish up taking photos of plants before the place is razed to become a HDB estate. Together with another enthusiastic lover of wildflowers, we went searching for macro subjects.

One of the oddities I found was this little herb. The leaves are clearly Desmodium triflorum but the flowers are white instead of purple!

The purple flower Desmodium triflorium grows just beside the white one on the same grass patch. I tried to see if they belong to the same individuals by tracing their creeping horizontal stems but they are apparently not.

This is another similar species, Desmodium heterophyllum but it has larger leaves and the flowers are also starkly different close-up. The white flower Desmodium however is similar to D. triflorium in every aspect. I wonder if it is a variety or an entirely new species yet to be recorded in Singapore? :x

Update: Was just updated that this might indeed be just a variety of Desmodium triflorium. Oh well..
