These fleshy, angular, warty stems bear a series of vermiform (shaped like a worm) outgrowths commonly referred to as roots, ± 10 mm long, which connect to the roots of the host.

Hydnora is a poorly known genus of parasitic plants from Africa and southern Arabia. ex Hook.
It grows very close to its host plant but may not be seen in the drier parts of the year. Initially, the flower is composed of three thick lobes that are fused together. Hydnora Hydnora africana Scientific classification Kingdom: Plantae Clade: Tracheophytes Clade: Angiosperms Clade: Magnoliids Order: Piperales Family: Aristolochiaceae Subfamily: Hydnoroideae Genus: Hydnora Thunb. Hydnora africana Thunb., 1775 Synonyms . Numerous stiff bristles are found on the inner surface of the perianth lobes which prevent the trapped insect from escaping.
This very active and well-travelled Swedish botanist discovered and collected the first known records of The flowers bears no resemblance to normal flowers except for its bright salmon to orange-red colour on the inside, which fulfils the same purpose as normal flowers, namely to advertise the plant.
The flower is spherical, brown on the outside and bright salmon to orange on the inner surface. Oken; Aphyteia hydnora Ach.
After feeding on the bait bodies, the trapped insect drops down the flower tube onto the anthers, collecting pollen all over its body. Genus: Hydnora Species: Hydnora africana.
After the plant has grown and spread, it may develop several secondary haustoria, attaching itself to the same or different host nearby.The plants have modified their roots in such a way as to ensure invasion of the potential host's tissue. Cette famille botanique rassemble des plantes qui ressemblent à des champignons car elles sont dépourvues de feuilles et ne produisent pas …
The seeds are numerous and small, and are embedded in a gelatinous, edible fleshy pulp which is rich in starch.There are two genera that belong to the Hydnoraceae family; For hundreds of years, jackal food was well known by the indigenous inhabitants of southern Africa.
It then drops even further down onto the soft cushion-shaped stigma and thus pollinates the flower.Not much is known about the germination of the seeds except that they are more likely to germinate in close proximity to the host plant.
Hydnora africana flowers are bisexual and develop underground.
Hydnora africana Facts Firstly, the somewhat unusual term of Hydnora africana serves as the scientific name of a legitimately amazing variety of achlorophyllous plant.
As it ages, the plant turns dark grey to black. Flowers may not appear for a number of years until sufficient rain has fallen.

Hydnora longicollis Welw. Name . It is thought that the plant excretes powerful enzymes that dissolve away the hard tissue of the host in order to attach itself. The plant body is completely leafless, is devoid of chlorophyll, and is brown-grey in colour. The plant body is only visible when the developing flowers push through the ground.The buds of these bisexual flowers develop underground, and eventually emerge to reach a height of about 100 to 150 mm. The stamens are situated halfway down the perianth tube which is 10-20 mm wide. White bait bodies are found on the inner base of the flowers. The fruit is a subglobose (half-round), underground berry with a thick, leathery wall epidermis/skin.
Once established, the plant is able to live off the nourishment from the host and quickly develops a matrix of underground stems from which the flower buds develop and eventually emerge above the ground.
