• Genus: Stenospermation
• Botanical Background: The species name honors the legacy of noted botanist Bassett Maguire, whose work in tropical botany greatly influenced the study of neotropical flora

• Geographical Range: Native to the tropical rainforests of the Guiana Shield and adjacent regions of South America; thrives in shaded forest understories
• Environment: Naturally grows in consistently humid conditions with well-draining, organic soils and a stable, warm climate typical of lowland tropical forests

• Medium-sized
• Heart-shaped leaves
• Glossy texture and subtle variegation that accentuates its overall ornamental appeal

Inflorescence (Spadix & Spathe)

• Modest green spathe paired with a slender spadix
• Colors are muted
