Sladeniaceae
Sladeniaceae is a family of flowering plants containing tree species found in subtropical to tropical environments in East Africa ('' Ficalhoa''), Burma, Yunnan, and Thailand ('' Sladenia''). The family consists of trees with alternate, simple leaves without stipules, and flowers arranged in cymose inflorescences. The circumscription of the family is variable, with some systems describing the family as consisting solely of the genus ''Sladenia'', which has been variously considered a member of the Theaceae, the Actinidiaceae, the Dilleniaceae, or the Ternstroemiaceae. Other systems include the genus '' Ficalhoa'' and possibly the genus '' Pentaphylax'' in a family with ''Sladenia''. Morphological studies of the ''Sladenia'' embryo suggest it has unique characteristics that merit placing the genus in its own family. However, the plant family is poorly studied and initial phylogenetic studies have raised contradictory indications about its taxonomic Taxonomy is t ...

Ericales Families
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of f ...

Ficalhoa
''Ficalhoa'' is a genus with only one species, ''Ficalhoa laurifolia'', an evergreen flowering tree of height with glabrous branches. Its bark is roughly fissured and produces white latex. Its leathery leaves on long petioles are lanceolate, rounded at the base, long and wide. Its white, yellowish or greenish flowers have oblong small petals and rounded sepals. In the Udzungwa Mountains it grows in elevations of in association with ''Aphloia theiformis'', '' Englerophytum magalismontanum'', '' Cryptocaria liebertiana'', '' Hirtella megacarpa'', ''Isoberlinia scheffleri'', '' Rapanea melanophloeos'', '' Xylopia aethiopica'' and ''Xymalos monospora''.

Actinidiaceae
The Actinidiaceae are a small family of flowering plants. The family has three genera and about 360 species and is a member of the order Ericales. Distribution They are temperate and subtropical woody vines, shrubs, and trees, native to Asia ('' Actinidia'' or kiwifruit, '' Clematoclethra'', and ''Saurauia'') and Central America and South America (''Saurauia'' only). ''Saurauia'', with its 300 species, is the largest genus in this family. Although now confined to Asia and tropical Central and South America, evidence indicates in the past the family had a wider distribution. The now extinct genus ''Parasaurauia'' is thought to have belonged to the Actinidiaceae and lived in North America during the early Campanian. Characteristics The plants are usually small trees or shrubs, or sometimes vines (''Actinidia''). The alternate, simple, spiral leaves have serrated or entire margins. They lack stipules or are minutely stipulated. They are often beset with rather flattened brist ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Pentaphylax
''Pentaphylax'' is a genus of flowering plants, with one or two species which are shrubs and small trees. The species has simple evergreen leaves that are alternately arranged on the stems. The flower pistil is 5 celled and the anthers dehiscing via pores and basifixed. Flowers have five petals and five sepals that are distinct from each other and five stamens attached oppositely to the sepals. The seeds are winged. Native from Tropical areas of South China to Malay Peninsula and Sumatra. Species include: *''Pentaphylax euryoides'' Taxonomy The APG III system of 2009 places the genus in the family Pentaphylacaceae, along with genera formerly placed in the Ternstroemiaceae. ''Pentaphylax'' has often been placed in its own family, the Pentaphylacaceae, separated from the Theaceae or Ternstroemiaceae based on the structure of the anthers and, arguably, the ovules. However, some molecular data and curved embryos (typical of the Ternstroemiaceae) point to a close relationship wit ...

Dilleniaceae
Dilleniaceae is a family of flowering plants with 11 genera and about 430 known species. Such a family has been universally recognized by taxonomists. It is known to gardeners for the genus ''Hibbertia'', which contains many commercially valuable garden species. Description and distribution The family is found in the tropics and subtropics plus all of Australia. Most of the members in it are woody plants - lianas or trees such as ''Dillenia'' - but herbaceous species such as ''Hibbertia'' are also present in Dilleniaceae. The leaves of the plants in the family are wide and well-developed, but in certain species of ''Hibbertia'' they are strongly modified. The flowers are mainly showy and colorful with visible reproductive components. Buzz pollination is common in the group. Fruits of some species, such as ''Dillenia indica'' (elephant apple), are edible. Taxonomy and phylogeny left, '' Dillenia suffruticosa'' The position of the family in the phylogenetic tree and its classific ...

Theaceae
Theaceae (), the tea family, is a family (biology), family of flowering plants comprising shrubs and trees, including the economically important tea plant, and the ornamental camellias. It can be described as having from seven to 40 genus, genera, depending on the source and the method of circumscription used. The family Ternstroemiaceae has been included within Theaceae;Royal Botanic Gardens, Kew. ''Vascular Plant Families and Genera''TheaceaeWatson, L., & Dallwitz, M. J. (1992 onwards). ''The families of flowering plants''/ref> however, the APG III system of 2009 places it instead in Pentaphylacaceae. Most but not all species are native species, native to China and East Asia. Family traits Plants in this family are characterized by simple leaves that are alternate spiral to distichial, serrated, and usually glossy. Most of the genera have evergreen foliage, but ''Stewartia'' and ''Franklinia'' are deciduous. The toothed margins are generally associated with a characteristic T ...
