Remember when I said the Drynoms aren’t dry enough to leave behind life near the surf? Well, this thing is actually that dry.
Previously inhabited exclusively by pissbaby plants, the humid inland of Dingus has become home to a color that’s a natural counter to piss yellow (because urinal cake), of course represented by terrestrial nomflora. The first Driernoms were derived from a population of Drynom which somehow became further away from the surf than what should be its neighbors. These nomflora were able to retain water better than their ancestry and can form more cohesive structures than mere filmy colonies; the latter is important as this means the Driernoms are considered true multicellular flora.
As Driernoms are multicellular, constituent cells can now devote themselves to different functions. Above the ground, leaflets are formed which house much of the organism’s photosynthetic (light-nomming) cells. Underground, there are rhizoids which hold the organism down into the soil and can draw up water and nutrients.
A Driernom can practice two modes of reproduction: If it is in an area of abundant nutrients, it can grow and bud off new noms from runners. If it grows in nutrient-poor soil, it will instead produce tiny airborne spores which will hopefully settle in richer lands.
