Monodora globiflora explained

Monodora globiflora is a species of plant in the family Annonaceae. It is native to Tanzania.[1] Thomas Couvreur, the botanist who first formally described the species, named it after its inner petals that touch one another, but are not fused, and form a globe-shaped structure.[2]

Description

It is a tree reaching 4 meters in height. Its branches have lenticels. Its papery leaves are 12-13 by 4-5 centimeters and come to a point at their tips. The leaves are smooth on their upper and lightly hairy on their lower surfaces. Its petioles are 8 millimeters long. Its pendulous flowers are solitary and axillary. Each flower is on a thin, lightly hairy pedicel 40-45 millimeters long. Its flowers have 3 sepals that are 8-10 by 6-8 millimeters long with densely hairy margins. Its 6 petals are arranged in two rows of 3. The smooth outer petals are light yellow with red highlights, or light green with dark green highlights, and curve slightly backwards. The outer petals are 28-32 by 18-23 millimeters and have wavy margins. The inner petals have a 3-5 by 2-4 millimeter claw at their base and a 7-8 by 10-12 millimeter blade, and are the same color as the outer petals. Its stamens are 0.8 millimeters long. Its smooth fruit are 4-5 centimeters in diameter. Its seeds are 15 by 7 millimeters.

Reproductive biology

The pollen of M. globiflora is shed as permanent tetrads.[3]

Habitat and distribution

It has been observed growing in sandy soils in sparse mountain forests, at elevations from 1700 to 2000 meters.[2]
