Ecologists classify plants by their habitat-driven water relations into hydrophytes (water/marsh plants), mesophytes (plants of moderately moist, well-drained habitats), xerophytes (plants adapted to dry/arid conditions) and lithophytes (plants growing on rock surfaces). Aeschynomene aspera is rooted in shallow, stagnant, waterlogged marshes, ponds and ditches across India, and like other hydrophytes it develops adaptive features for this environment -- most notably an extensive, lightweight, spongy pith (aerenchyma-like tissue) in its stem that provides buoyancy and internal aeration under waterlogged, low-oxygen soil conditions. This spongy pith is economically significant: it is harvested, dried and carved to make sola (pith) hats, pith helmets and d …
