The species occurs from Central America through the Caribbean to much of tropical South America, where it grows primarily in humid lowland rainforests. It is characterized by its long, creeping rhizomes and its conspicuously large, leathery, undivided fronds, which are considerably larger than those of most other species in the genus.\u003c\/p\u003e\u003cp\u003eAlthough \u003cem\u003eM. megalophylla\u003c\/em\u003e does not develop swollen rhizomes, it maintains a close association with ants. Its creeping rhizomes grow tightly appressed to the substrate, creating narrow spaces between the rhizome and the tree bark that are used by various ant species as nesting sites and passageways. The ants deposit organic material in these spaces, providing the fern with an additional source of nutrients. Unlike the former \u003cem\u003eSolanopteris\u003c\/em\u003e species, however, these nesting sites are not formed by specialized domatia or swollen rhizomes.\u003c\/p\u003e\u003cp\u003eA similar strategy is found in \u003cem\u003eLecanopteris mirabilis\u003c\/em\u003e, several species of the genera \u003cem\u003eHoya\u003c\/em\u003e and \u003cem\u003eDischidia\u003c\/em\u003e, and the epiphytic cacti \u003cem\u003eDeamia testudo\u003c\/em\u003e and \u003cem\u003eStrophocactus wittii\u003c\/em\u003e. In all of these plants, ants occupy the natural spaces between the plant and the bark of the host tree without the formation of specialized domatia. \u003cem\u003eMicrogramma megalophylla\u003c\/em\u003e therefore represents a remarkable example of a comparatively simple form of myrmecophily, in which a close symbiosis with ants has evolved without pronounced morphological specialization.\u003c\/p\u003e","brand":"AW (ドイツ)","offers":[{"title":"01 \/ L","offer_id":49119141757163,"sku":"AW-Micro_mega.1","price":36340.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/4003\/6843\/files\/Microgramma_megalophylla_1.webp?v=1786448090","url":"https:\/\/os-nursery.jp\/products\/microgramma-megalophylla-aw-micro-mega","provider":"大森食虫植物農園","version":"1.0","type":"link"}
