Abolboda scabrida

Abolboda scabrida is a herbaceous monocot in the family Xyridaceae, order Poales, endemic to the tropical savanna and highland wetland regions of South America. The specific epithet scabrida means rough or scabrous, referring to a texture of roughness present on the leaves, stems, or inflorescence axes of this species, which distinguishes it from smoother-surfaced congeners. This textural characteristic may serve as an adaptation to specific environmental conditions, such as improving boundary layer conditions for gas exchange or deterring herbivores in the open savanna habitats the plant occupies. Like all members of the genus Abolboda, Abolboda scabrida is native to the Guiana Highlands and surrounding lowland savannas, inhabiting wet grasslands, seasonally flooded meadows, tepui slopes, and white-sand savannas of Venezuela, Guyana, Suriname, Colombia, and northern Brazil. These habitats are underlain by ancient Precambrian rocks of the Guiana Shield and support a remarkable diversity of endemic plant species that are adapted to nutrient-poor, highly acidic soils. The vegetative structure of Abolboda scabrida consists of a basal rosette of linear, narrow leaves arising from a compact stem. The leaf surfaces bear the roughness implied by the epithet, setting this species apart visually and texturally from related taxa. The plant produces erect flowering scapes that terminate in spikes of small, three-petaled flowers. These flowers are likely blue to violet in coloration, consistent with the dominant floral color of the genus. The Xyridaceae family, which includes Abolboda, is characterized by rush-like to grass-like monocots adapted to wet, open, often nutrient-impoverished environments across the tropics and subtropics.
