List of Clusiaceae genera

List of Clusiaceae genera is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of Clusiaceae genera rather than just read about it. In short: Delineation of plant family Clusiaceae, and the subdivisions within the family, have been much revised over the past few decades. Accepted genera 18 genera are currently accepted: Arawakia L.Marinho Chrysochlamys Poepp.

Key takeaways

List of Clusiaceae genera belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of Clusiaceae genera to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of Clusiaceae genera from memory before moving on to harder problems.

Reference excerpt

Delineation of plant family Clusiaceae, and the subdivisions within the family, have been much revised over the past few decades.

Accepted genera 18 genera are currently accepted:

Arawakia L.Marinho Chrysochlamys Poepp. Clusia Plum. ex L. Dystovomita (Engl.) D'Arcy Garcinia L. Havetiopsis Planch. & Triana Lebrunia Staner Lorostemon Ducke Montrouziera Pancher ex Planch. & Triana Moronobea Aubl. Nouhuysia Lauterb. Pentadesma Sabine Platonia Mart. Quapoya Aubl. Symphonia L.f. Thysanostemon Maguire Tovomita Aubl. Tovomitopsis Planch. & Triana

Classification The family Clusiaceae was divided by Cronquist into 2 subfamilies: the Clusioideae (typical subfamily) and the Hypericoideae. The latter was often treated as a family - the Hypericaceae or St. John's wort family. Elements of the Hypericoideae are more common in North temperate areas and those of the Clusioideae are centered in the Tropics. Later classifications however divide the family in a finer way. The taxonomy below mostly follows that of Stevens. Molecular studies have shown that the family Podostemaceae - the riverweeds - as well as the Theaceae-segregate Bonnetiaceae need to be included in this group. Their inclusions make Clusiaceae in a wide-sense polyphyletic, and Stevens's subfamilies need to be recognised at family level: Clusioideae as Clusiaceae sensu stricto; Hypericoideae as Hypericaceae; and Kielmeyeroideae as Calophyllaceae.

Subfamily Clusioideae Synonyms are in parentheses:

Tribe Clusieae Arawakia L.Marinho Chrysochlamys Poepp. (Balboa Planch. & Triana, Commirhoea Miers, and Poecilostemon Triana & Planch.) Clusia (Androstylium, Cochlanthera, Decaphalangium, Havetia, Havetiopsis, Oedematopus, Oxystemon, Pilosperma, Quapoya, Renggeria, Rengifa, etc.) Dystovomita (Engl.) D’Arcy Tovomita Aubl. (Beauharnoisia Ruiz & Pav., Euthales F.Dietr. Marialva Vand., Micranthera Choisy, and Tovomitidium Ducke) Tovomitopsis Planch. & Triana (Bertolonia Spreng.) Tribe Garcinieae Garcinia (Allanblackia, Brindonia, Cambogia, Clusianthemum, Mangostana, Oxycarpus, Pentaphalangium, Rheedia, Septogarcinia, Tripetalum, Tsimatimia, Verticillaria, Xanthochymus) - saptree, mangosteen Tribe Moronobeeae Moronobea Tribe Platonieae Platonia (Aristoclesia) Tribe Symphonieae Lorostemon Pentadesma Montrouziera Symphonia (Actinostigma Welw., Aneuriscus C.Presl, Chrysopia Noronha ex Thouars) Thysanostemon Tribe incertae sedis Havetiopsis Planch. & Triana Lebrunia Staner †Mammeoxylon Nouhuysia Lauterb. Quapoya Aubl.

Subfamily Hypericoideae This subfamily comprises 3 tribes; synonyms are in parentheses:

Tribe Cratoxyleae Cratoxylum (Cratoxylon) Eliea (Eliaea) Thornea Triadenum - marsh St. Johnswort Tribe Hypericeae Hypericum (Adenotrias, Androsaemum, Androsemum, Ascyrum, Lianthus, Olympia, Sanidophyllum, Sarothra, Takasagoya, Triadenia) - St John's Wort Santomasia Tribe Vismieae Harungana (Haronga) Psorospermum Vismia

Subfamily Kielmeyeroideae This subfamily comprises 2 tribes:

Tribe Calophylleae (12 genera) Calophyllum Caraipa Clusiella (Asthotheca, Astrotheca) Haploclathra Kayea Kielmeyera Mahurea Mammea (Ochrocarpos, Paramammea) - mammee apple (sometimes put in Garcinieae) Marila Mesua (Vidalia) Neotatea Poeciloneuron Tribe Endodesmieae (contains 2 African monotypic genera) Endodesmia Lebrunia

Worked examples

Example 1 — a first encounter with List of Clusiaceae genera

Start with the simplest possible case. Write down what List of Clusiaceae genera claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of Clusiaceae genera before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of Clusiaceae genera ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of Clusiaceae genera

In research: List of Clusiaceae genera appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of Clusiaceae genera in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of Clusiaceae genera is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clusiaceae, Clusiaceae genera, Lists of plant genera (alphabetic), so understanding it makes those chapters shorter.
In everyday life: Look for List of Clusiaceae genera outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
