**Microgramma vacciniifolia (short-leaf form)**
A compact epiphytic fern native to tropical and subtropical regions of South America, *Microgramma vacciniifolia* grows on tree trunks and rocky surfaces within humid forests. This particular short-leaf form is distinguished by its dense, creeping rhizomes and small, leathery fronds with a glossy surface. The fronds are elliptic to lanceolate, typically remaining under 4 cm in length, forming a tidy, mat-like growth ideal for terrarium and vivarium settings. Its adaptability and restrained size make it highly suited for close-up plantings or miniature displays.
