Cercestis Stigmaticus
''Cercestis'' is a genus of flowering plants in the family Araceae. The species in this genus are all climbers and are native to Africa. At intervals along the stem they produce long leafless shoots called flagella. Many of the species in ''Cersestis'' show signs of fenestration.Bown, Demi (2000).

Cercestis Mirabilis
''Cercestis mirabilis'' is a perennial herb that can grow up to tall. It is an obligate climber, which means that it requires support to grow. The stem is about thick and can climb up to a height of , rooting as it climbs. The juvenile leaves are saggitate with white markings. The adult leaves are about long, simple, broad, and glabrous, with a terete petiole Petiole may refer to: *Petiole (botany), the stalk of a leaf, attaching the blade to the stem *Petiole (insect anatomy) In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and ... that is long and grooved at the base in the adult plant.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Description Within the Araceae, species are often rhizomatous or tuberous; many are epiphytic, creeping lianas or vining plants, and the leaves and tissues of the entire plant nearly always contains irritating calcium oxalate crystals or raphides, in varying degrees. The foliage can vary considerably from species to species. The majority of species produce an inflorescence consisting of a spadix (which some compare to a corn cob, in appearance), which is nearly always surrounded ...

Perforate Leaf
Perforate leaves, sometimes called fenestrate, occur naturally in some species of plants. Holes develop as a leaf grows. The size, shape, and quantity of holes in each leaf can vary greatly depending on the species and can even vary greatly within a given species. Perforation is caused by sections of leaf ceasing cell growth or by dying during an early stage in the development of the leaf. These deformations that are created earliest in the leaf development end up looking more like slashes whereas those that develop later end up looking more like holes. This trait is found in only one species in Aponogetonaceae, ''Aponogeton madagascariensis'' (Madagascar laceleaf), and a few genera in Araceae, particularly '' Monstera''. It is not fully known what evolutionary purpose perforation serves, but there are several possibilities. Perforation could serve the purpose of reducing the variations in growth rate, minimize chances of leaves tearing in high winds or it could help to maximize ...
