Uvariastrum insculptum is a species of plant in the Annonaceae. It is native to Cameroon, Gabon, Ghana, Ivory Coast, Liberia, Nigeria, and the Republic of the Congo. [2] Adolf Engler and Ludwig Diels, the botanists who first formally described the species using the basionym Uvaria insculpta, named it after the secondary veins on its leaves which are distinctly sunken (insculptus in Latin). [3]
Uvariastrum insculptum is a shrub or tree reaching 4–15 meters in height. The young, brown branches are hairy, but become hairless and brown-grey with maturity. Its narrowly elliptical to egg-shaped, papery to slightly leathery leaves are 6–14 by 2–4 centimeters. The leaves have rounded to slightly heart-shaped bases and tapering tips, with the tapering portion 1–2 centimeters long. The leaves are hairless to very sparsely hairy on their dark green upper and lower surfaces. The leaves have 8–12 pairs of secondary veins emanating from their midribs. The secondary veins connect toward the margins of the leaves and are distinctly recessed. Its petioles are 1–4 by 1 millimeters, and covered in dense red-brown hairs, with an indistinct groove on their upper side.
Uvariastrum insculptum has solitary or paired Inflorescences occurring on branches and sometimes the trunk. Each inflorescence has 1 flower. Each flower is on a densely hairy pedicel that is 0.8–1.5 by 1–2 millimeters. The pedicels have 1–3 densely hairy basal bracts that are 4 by 3–4 millimeters. Its flowers have 3 oval sepals that are 0.7–1.5 by 5–8 millimeters. The bases of the sepals are flat, and their tips are pointed. The sepals are densely hairy on both surfaces. The sepals are light green to pale yellow and darker at their margins which are slightly folded. Its 6 petals are arranged in two rows of 3. The white to pale yellow to light brown, oval, outer petals are 2.3-3.5 by 0.5–1 centimeters. The upper surface of the outer petals is densely covered in downy to woolly hairs, and the lower surfaces are sparsely covered in downy to woolly hairs. The white to pale yellow to light brown, oval inner petals are 1–2 by 0.6–1 centimeters with densely hairy upper and lower surfaces. The inner petals are narrower at the base and pointed at the tips. The flowers have numerous bright red densely hairy stamens that are 2-2.5 by 0.5 millimeters. The flowers have up to 6–7 carpels that are 2–3 by 1 millimeters, and densely hairy. The carpels have bilobed stigma that are 1.5 millimeters in diameter, hairless and yellow. Each carpel has up to 19–26 ovules arranged in two rows.
The fruit occur in clusters of 2–8 on sparsely to densely hairy pedicles that are 10–20 by 2–5 millimeters. The densely hairy, oblong fruit are 3–6 by 1–2 centimeters and are sometimes bent. The surface of the fruit is ribbed in network pattern. Each fruit has up to 20 dark brown, flat, elliptical seeds that are 10–15 by 7–9 by 3–5 millimeters. [4]
The pollen of Uvariastrum insculptum is shed as permanent tetrads. [5]
It has been observed growing lowland primary and secondary rain forests at altitudes up to 400 meters. [4]
Asteranthe asterias is a species of plant in the family Annonaceae. It is native to Kenya and Tanzania. Spencer Le Marchant Moore, the English botanist who first formally described the species using the basionym Uvaria asterias, did not explicitly explain the epithet, but was likely referencing the star-like appearance of its flower’s petals.
Hexalobus bussei is a species of plant in the family Annonaceae. It is native to Cameroon. Ludwig Diels, the German botanist who first formally described the species, named it after another German botanist, Walter Busse, who collected the sample that Diels examined.
Mitrephora keithii is a species of plant in the family Annonaceae. It is native to Myanmar, Peninsular Malaysia and Thailand. Henry Nicholas Ridley, the English botanist who first formally described the species, named it in honor of Dr. A. Keith who collected the sample that Ridley examined.
Mitrephora calcarea is a species of plant in the family Annonaceae. It is native to Laos and Vietnam. Aruna Weerasooriya and Richard M.K. Saunders, the botanists who provided the first valid formal description of the species, named it after the limy soil it grows in. The name follows a prior invalid account by Suzanne Jovet-Ast, which lacked a Latin description.
Mitrephora tomentosa is a species of plant in the family Annonaceae. It is native to Bangladesh, Cambodia, Laos, Myanmar, Thailand, and Vietnam. Joseph Hooker and Thomas Thomson, the British botanists who first formally described the species, named it after the dense covering of hair on its young branches, leaves and flowers.
Neostenanthera gabonensis is a species of plant in the family Annonaceae. It is native to Cabinda Province, Cameroon, Equatorial Guinea, Gabon, Ghana, Ivory Coast, Liberia, and The Republic of the Congo. Heinrich Gustav Adolf Engler and Ludwig Diels, the German botanists who first formally described the species, using the basionym Oxymitra gabonensis, named it after Gabon where the specimen they examined was found near a site they identified as Sibange-Farm.
Pseuduvaria dielsiana is a species of plant in the family Annonaceae. It is native to New Guinea. Carl Lauterbach, the German botanist who first formally described the species using the synonym Goniothalamus dielsianus, named it in honor of Ludwig Diels, another German botanist who also worked on taxa from New Guinea.
Pseuduvaria kingiana is a species of plant in the family Annonaceae. It is native to the Malay Peninsula. Yvonne Chuan Fang Su and Richard Saunders, the botanists who first formally described the species, named it after Sir George King, the British botanist who first collected the species.

Pseuduvaria mindorensis is a species of plant in the family Annonaceae. It is native to the Philippines. Yvonne Su and Richard Saunders, the botanists who first formally described the species, named it after the island of Mindoro where the specimen they examined was collected in the municipality of Puerto Galera.
Pseuduvaria guineensis is a species of plant in the family Annonaceae. It is native to New Guinea. James Sinclair, the Scottish botanist who first formally described the species, named it after New Guinea where the specimen he examined was collected near Kokoda.
Pseuduvaria pamattonis is a species of plant in the family Annonaceae. It is native to Borneo and the Philippines. Friedrich Miquel, the Dutch botanist who first formally described the species using the basionym Orophea pamattonis, named it after a mountain in Borneo called Gunung Pamaton.
Pseuduvaria parvipetala is a species of plant in the family Annonaceae. It is native to Borneo and Sumatra. Yvonne Su and Richard Saunders, the botanists who first formally described the species, named it after its small petals.
Pseuduvaria reticulata is a species of plant in the family Annonaceae. It is native to Bangladesh, Borneo, Java, the Lesser Sunda Islands, Myanmar and Sumatra. Carl Ludwig Blume, the botanist who first formally described the species under the basionym Uvaria reticulata, named it after the net-like pattern of veins on the underside of its leaves.
Pseuduvaria sessilifolia is a species of plant in the family Annonaceae. It is native to New Guinea. James Sinclair, the botanist who first formally described the species, named it after its stalkless leaves which lack petioles.

Uvariastrum hexaloboides is a species of plant in the Annonaceae family. It is native to Tanzania, Zambia and Zaire. Robert Elias Fries, the botanist who first formally described the species using the basionym Uvaria hexaloboides, named it after a different species Hexalobus monopetalus which he thought its flowers and vegetative parts resembled.
