## Overview
Dictyostega is a small genus of herbaceous plants characterized by their dependence on symbiotic relationships with fungi for nutrition, a trait known as mycoheterotrophy. Unlike most plants, Dictyostega species lack chlorophyll and do not perform photosynthesis, relying instead on fungal partners to obtain nutrients from the soil.
## Taxonomy and Distribution
Belonging to the family Burmanniaceae, Dictyostega comprises a few species primarily distributed across tropical rainforests in Central America, the Caribbean, and northern South America. These plants are typically found in shaded, humid forest understories where fungal networks are abundant.
## Morphology
Dictyostega species exhibit small, delicate flowers with unique structural adaptations. Their flowers often have a tubular shape with intricate veining patterns, which aid in attracting specific pollinators. The plants grow from underground rhizomes and produce slender stems that emerge above the leaf litter.
## Ecology
As mycoheterotrophs, Dictyostega plants form essential ecological connections with mycorrhizal fungi, which in turn associate with photosynthetic trees. This tripartite relationship allows Dictyostega to thrive in nutrient-poor environments where direct photosynthesis is not feasible.
