Monandra

Monandra is a genus of flowering plants in the family Araceae, commonly known as arums or aroids. This genus is native to the tropical and subtropical regions of Southeast Asia and the western Pacific. Plants in the genus Monandra are characterized by their distinctive inflorescence, which consists of a spathe and a spadix. The spathe is a modified leaf that encloses the spadix, which bears numerous small flowers.

Species within Monandra are typically terrestrial or epiphytic herbs. They often possess attractive, sagittate (arrowhead-shaped) or hastate (halberd-shaped) leaves, which can be plain green or have intricate patterns of venation and coloration. The root systems vary, with some species having rhizomes and others tubers. The flowers, when present, are usually inconspicuous and are often pollinated by insects.

The exact taxonomic classification of Monandra has been subject to revision over time, with some species formerly placed in this genus now classified elsewhere, and vice-versa. Its relationship to other genera within Araceae is a subject of ongoing botanical research. The ecological roles of Monandra species are diverse, contributing to the biodiversity of their native habitats. Some species are cultivated for their ornamental foliage, while others have traditional uses in their regions of origin. Further scientific study continues to reveal the intricacies of this genus's biology and evolutionary history.
