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.
Guttation is the exudation of drops of xylem and phloem sap on the tips or edges of leaves of some vascular plants, such as grasses, and also a number of fungi. Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the ...
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 leaf of Philodendron maximum. The leaves are usually large and imposing, often lobed or deeply cut, and may be more or less pinnate. They can also be oval (Philodendron 'White Princess'), spear-shaped, divided (Philodendron tripartitum) or in many other possible shape variations. The leaves are borne alternately on the stem.
Split-leaf philodendron is a common name for several plants in the Araceae family, which may refer to: Monstera deliciosa , a species with lobed and perforated leaves bearing edible fruit Thaumatophyllum bipinnatifidum , a species with large pinnately-lobed leaves
A series of molecular phylogenetic studies, particularly from 2008 onwards, suggested that, when broadly circumscribed, Philodendron was not monophyletic. In 2018, it was proposed that subgenus Meconostigma should be raised to the rank of genus, under the name Thaumatophyllum . [ 2 ]
Thaumatophyllum spruceanum is noted for its unusually hoop-shaped, parallel-pinnately veined, pedately divided leaves; [2] these are similar to those of the sympatric species Thaumatophyllum leal-costae. [3] Each leaf consists of 10-20 leaflets, with the central leaflet 18–50 cm long. [4]
At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. Root pressure is studied by removing the shoot of a plant near the soil level. Xylem sap will exude from the cut stem for hours or days due to root pressure. If a pressure gauge is attached to the cut stem, the root ...
