Up until recently, non-vascular multicellular nomflora diversity has been rather limited; the humble Driernom, progenitor of the successful Nomherb and Nomweed divisions, rarely gave rise to descendant flora which remained moss-grade, and thus has been eking out a subtle, quiet living throughout countless generations. Nonetheless, the niche for hardy moss-like flora seemed disturbingly absent beyond Dingus, and to a population of divergent mutant Driernoms, this presented an incomparable opportunity to spread their rhizoids and make their patches of pisscake cyan known throughout 2s2tworld.

Compared to the ancestral Driernom, Nommoss growth occurs in a manner more reminiscent of an organized pattern - whorls of leaflets grow from the center and spread outwards, with a new whorl starting to develop once the previous whorl reaches a certain circumference and leaflet width. It is due to this distinct growth pattern that Nommosses, in spite of their versatility, have not replaced their ancestry.

For such unsophisticated, basal flora, Nommosses are predictably quite hardy, with most species not found in densely-forested lands requiring comparatively little resources. It is not uncommon to find a rock covered with varied hues of pisscake blue - hues which are responsible for the presence of Nommosses. No matter which ecology you observe in - from shaded rainforest floors to montane desert crags, you can always expect to find at least a couple of species of this patchy cyannery. Perhaps due to their hardiness, many species of of Nommoss house various cultures of Nitropellet within their rhizoids. These cultures not only provide their hosts with sequestered nitrogenous compounds essential for their maintenance, but allow them to gain a foothold on barren surfaces - and when covered with a considerable number of Nommosses, these surfaces are broken down, releasing precious nutrients into the newborn soil. Because of this phenomenon, these species of Nommoss can be considered pioneer flora, playing an extremely crucial role in the formation and renewal of ecological communities.

Nommoss species occur in a wide variety of climates, and certain morphological trends can be noted with each climate type. Species found in humid forests tend to have longer, wider leaflets. As one ventures into drier conditions, leaflets become more compact to retain water. What few species are found in deserts have compact, narrow leaflets and typically grow where there's consistent shade; beach-dwelling Nommosses possess similar anti-desiccation adaptations. Nommosses found in cold climates have short and narrow leaflets to retain heat, while also sporting a dark azure coloration to make the most of the scarce exposure to light. Owing to their Dingusian heritage, many species of Nommoss contain trace quantaties of insulating lead, which not only shields against radiation, but allows certain species to thrive in drier climes. Because of this, they have notably become the first few nomflora to viably settle into the continent’s drier ecologies - lands which have previously seen the exclusive dominance from goldy-derived flora. A key component to the diversity of Nommosses is the innovation of sexual reproduction, allowing for greater genetic variation and mutation rates. Reproductive structures facilitating this developed independently from both clades of vascular nomflora in the form of elongate sporophores growing from within whorls. Male gametes housed within are either carried directly via the wind or inadvertently brushed off by passing fauna, but either vector will yield the same outcome - dispersal to a sporophore containing female gametes. Upon fertilization, airborne spores are produced which will hopefully settle and germinate quite far from their parent population. This period occurs for most species either in late summer or the peak of the wet season. Alternatively, clonal individuals are bud from runner-like rhizoids in more fertile climates.

Occasionally these spores latch onto passing fauna, further securing chances for faraway dispersal. In fact, it is exactly due to fauna-based dispersal that owes to the Nommosses’ almost cosmopolitan presence - although first carried by maritime winds from Dingus to Kamm, successive generations of spores hitchhiked on passing radrakes and pig-o-dactyls until being deployed in suitable environments throughout Oofle, Beans, and Cube. The only landmass to miss out on these swathes of pisscake blue is the aptly-named horrible rectangle island, being nigh-inhospitable to any newcoming clades.
