Thaumatophyllum bipinnatifidum (common names: split-leaf philodendron, [1] lacy tree philodendron, selloum, horsehead philodendron, [2] guaimbé [citation needed]) is a plant in the genus Thaumatophyllum, in the family Araceae. Previously it was classified in the genus Philodendron within subgenus Meconostigma.
Thaumatophyllum xanadu is a species of the genus Thaumatophyllum, which previously was the self-heading Meconostigma subgenus of Philodendron. "It differs from all other species of Meconostigma in details of the sexual parts of its spadix, the shape of the leaf scars on the rhizomes, shape of leaf blade, intravaginal squamules, etc".
A primary hemiepiphytic philodendron starts life high up in the canopy where the seed initially sprouts. The plant then grows as an epiphyte. Once it has reached a sufficient size and age, it will begin producing aerial roots that grow toward the forest floor. Once they reach the forest floor, nutrients can be obtained directly from the soil.
These plants can be cultivated and bred as a long term phosphorus deficiency prevention method. Along with root size, other root adaptations to low phosphorus, such as mycorrhizal symbioses, have been found to increase nutrient intake. [10] These adaptations to roots work to maintain levels of vital nutrients.
Hypoxia can affect the nutrient uptake of a plant because, without oxygen present, respiration becomes inhibited within the root cells. The nutrient film technique is a hydroponic technique in which the roots are not fully submerged. Incomplete submergence allows for adequate aeration of the roots, while a "film" thin layer of nutrient-rich ...
The leaves and roots contain calcium oxalate crystals, which are moderately toxic to humans. Ingesting large quantities of either may produce symptoms including burning of the mouth and throat, swelling of the lips and tongue, vomiting, headaches, and dizziness; merely handling the fresh leaves can burn the skin.
These human uses have also spread many Arecaceae species around the world. [33] Along with dates mentioned above, members of the palm family with human uses are numerous: The type member of Arecaceae is the areca palm (Areca catechu), the fruit of which, the areca nut, is chewed with the betel leaf for intoxicating effects.
Nitrogen is a vital nutrient to plants and gaseous nitrogen (N 2) is not available to them due to the high energy required to break the triple bonds between the two atoms. [4] Rhizobacteria, through nitrogen fixation, are able to convert gaseous nitrogen (N 2 ) to ammonia (NH 3 ) making it an available nutrient to the host plant which can ...
