Basal angiospermsThe basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody aromatic plants including star anise). ANITA stands for Amborella, Nymphaeales, I lliciales, Trimeniaceae, and Austrobaileya.
AcheneAn achene (əˈkiːn; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed.
MagnoliopsidaMagnoliopsida is a valid botanical name for a class of flowering plants. By definition the class will include the family Magnoliaceae, but its circumscription can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed. In the Takhtajan system and the Cronquist system, the name was used for the group known as dicotyledons.
EuphorbiaceaeEuphorbiaceae (juːˈfoːrbiːˌeɪsiˌaɪ,_-siːˌiː), the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of the type genus of the family. Most spurges, such as Euphorbia paralias, are herbs, but some, especially in the tropics, are shrubs or trees, such as Hevea brasiliensis. Some, such as Euphorbia canariensis, are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution.
CeratophyllaceaeCeratophyllaceae is a cosmopolitan family of flowering plants including one living genus commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant family in the order Ceratophyllales. Species are commonly called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta. Living Ceratophyllum grows completely submerged, usually, though not always, floating on the surface, and does not tolerate drought.
LiliopsidaLiliopsida Batsch (synonym: Liliatae) is a botanical name for the class containing the family Liliaceae (or Lily Family). It is considered synonymous (or nearly synonymous) with the name monocotyledon. Publication of the name is credited to Scopoli (in 1760): see author citation (botany). This name is formed by replacing the termination -aceae in the name Liliaceae by the termination -opsida (Art 16 of the ICBN).
Habit (biology)Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: In zoology (particularly in ethology), habit usually refers to aspects of more or less predictable behaviour, instinctive or otherwise, though it also has broader application. Habitus refers to the characteristic form or morphology of a species. In botany, habit is the characteristic form in which a given species of plant grows (see plant habit).
