Flowering
Shallow, slow-flowing portion of river (river level in general very low); plants were over 10 meters away from the closest vantage point on the south bank; since leaves were not floating on the surface, assumption is that they are not dimorphic and that this is therefore var. diffusus; two groupings of plants observed only at this specific location
