Manihot carthaginensis subsp. glaziovii, also known as Manihot glaziovii, the tree cassava or Ceara rubber tree, is a species of deciduous flowering plant in the spurge family, Euphorbiaceae, that is native to eastern Brazil.

Description

Manihot carthaginensis subsp. glaziovii in Cotonou, Benin
  • Leaves - palmipartite, peltate; lobes broadly ovate to obovate; green above, glaucous beneath.[2]
  • Flowers - show branched inflorescence. Unisexual flowers are greenish-white or pale yellow with reddish markings.[3]
  • Fruit - globose.

Common names

  • French - manioc de ceara, maniçoba, ceara, caouchouc de ceara
  • Portuguese - manicoba
  • Swahili - mpira
  • Yoruba - gbaguda

Uses

The tree cassava was used a source of rubber, instead of Hevea brasiliensis throughout the world. The plant is introduced largely in the world, but now it is classified as one of the highly invasive plant of the world.[4]

Scientists found various enzymatic and inhibitory activities of tree cassava, which have insecticidal and anti-fungal proteins extracted from the latex of the plant. These proteins are effective against insects such as cowpea weevil, and fungi like Colletotrichum gloesporioides, Fusarium solani and Macrophomina phaseolina.[5] It could be used as graft shoot in a rootstock of edible cassava and increase 10 times the yield per acre.

Invasiveness

The species is invasive in New Caledonia.[6]
