'''Gentianaceae''' is a family of [[flowering plant]]s of 87 genera and about 1600 species.<ref name="Struwe2002">{{cite book|author=Struwe L, Albert VA|year=2002|title=Gentianaceae: systematics and natural history|publisher=Cambridge University Press|ISBN=0-521-80999-1}}</ref>

==Etymology==
 
−
The family takes its name from the genus ''[[Gentiana]]'', named after the Illyrian king [[Gentius]].
 
−
 
 
−
==Distribution==
 
−
Distribution is [[cosmopolitan (species)|cosmopolitan]].

==Characteristics==
 
−
The family consists of trees, shrubs and herbs showing a wide range of colours and floral patterns. [[Flower]]s are [[actinomorphic]] and bisexual with fused sepals and petals. The [[stamen]]s are attached to the inside of the petals ([[Stamens#Sexual reproduction in plants|epipetalous]]) and alternate with the corolla lobes. There is a glandular disk at the base of the gynoecium, and flowers have parietal placentation. The [[inflorescence]] is cymose, with simple or complex [[Cyme (botany)|cymes]]. The [[fruit]]s are dehiscent septicidal capsules splitting into two halves, rarely some species have a [[berry (botany)|berry]]. Seeds are small with copiously oily endosperms and a straight embryo. The habit varies from small [[tree]]s, pachycaul [[shrub]]s to (usually) [[herb]]s, with ascending, erect or twining stems. Plants are usually rhizomatous. Leaves [[opposite leaves|opposite]], less often alternate or in some species whorled, simple in shape, with entire edges and bases [[connation|connately]] attached to the stem. Stipules are absent. Plants usually accumulate bitter [[iridoid]] substances; bicollateral bundles are present. Ecologically, partial [[myco-heterotrophy]] is common among species in this family with a few genera such as ''[[Voyria]]'' and ''[[Voyriella]]'' lacking [[chlorophyll]] and being fully myco-heterotrophic.

==Ecology==
 
−
Some of these plants have limited ranges and are protected under governmental oversight. For example, ''[[Gentianella uliginosa]]'' (Dune Gentian), which occurs in some limited areas of [[Wales]] and [[Scotland]], is a priority species under the [[Biodiversity Action Plan]] of the [[United Kingdom]].{{Citation needed|date=August 2013}}

==Biogeographic History==
 
−
Gentianaceae are distributed worldwide, but most species occur in [[Temperate climate|temperate]] zones. According to Merckx et al.,<ref>{{cite journal|last1=Merckx|first1=Vincent S.F.T.|last2=Kissling|first2=Jonathan|last3=Hentrich|first3=Heiko|last4=Janssens|first4=Steven B.|last5=Mennes|first5=Constantijn B.|last6=Specht|first6=Chelsea D.|last7=Smets|first7=Erik F.|title=Phylogenetic relationships of the mycoheterotrophic genus Voyria and the implication for the biogeographic history of Gentianaceae|journal=American Journal of Botany|volume=100|issue=4|pages=712–721|doi=10.3732/ajb.1200330|url=http://www.amjbot.org/content/early/2013/03/26/ajb.1200330.full.pdf+html}}</ref> the [[neotropics]] were an important area for the early diversification events in Gentianaceae, most of which occurring during the [[Eocene]]. However, Pirie et al.<ref>{{cite journal|last1=Pirie|first1=Michael|last2=Litsios|first2=Glenn|last3=Bellstedt|first3=Dirk|last4=Salamin|first4=Nicolas|last5=Kissling|first5=Jonathan|title=Back to Gondwanaland: can ancient vicariance explain (some) Indian Ocean disjunct plant distributions?|journal=Biology Letters|volume=11|doi=10.1098/rsbl.2015.0086|url=http://rsbl.royalsocietypublishing.org/content/11/6/20150086|pmid=26063747|pmc=4528461|page=20150086}}</ref> suggested that ancient [[vicariance]] cannot be ruled out as an explanation for the early origins of [[Exaceae]] across [[Africa]], [[Madagascar]] and the Indian subcontinent unless a strong assumption is made about the maximum age of [[Gentianales]].

==Uses==
 
−
Economically, some species are cultivated [[ornamental plant]]s and many species yield bitter principles used medicinally and in flavorings.

==Taxonomy==
 
−
The family was described for the first time by [[Antoine Laurent de Jussieu]] in 1789.
