'''''Calystegia''''' ('''bindweed''', '''false bindweed''', or '''morning glory''') is a genus of about 25 species of [[flowering plant]]s in the bindweed family [[Convolvulaceae]]. The genus has a [[cosmopolitan distribution]] in temperate and subtropical regions, but with half of the species [[endemic (ecology)|endemic]] to [[California]].  They are [[annual plant|annual]] or [[herbaceous]] [[perennial plant|perennial]] twining [[vine]]s growing 1–5&nbsp;m tall, with spirally arranged leaves. The [[flower]]s are trumpet-shaped, 3–10&nbsp;cm diameter, white or pink, with (in most species) a sometimes inflated basal epicalyx.

The genus bears much similarity to a related genus ''[[Convolvulus]]'', and is sometimes combined with it; it is distinguished primarily by the [[pollen]] being smooth, and in the [[ovary (plants)|ovary]] being [[Locule|unilocular]].

Some of the species, notably ''[[Calystegia sepium]]'' and ''[[Calystegia silvatica|C. silvatica]]'', are problematic [[weed]]s, which can swamp other more valuable plants by climbing over them, but some are also deliberately grown for their attractive [[flower]]s.

''Calystegia'' species are eaten by the [[larva]]e of some [[Lepidoptera]] species including ''[[Bedellia somnulentella]]'' (recorded on ''C. sepium'') and [[small angle shades]].

The name is derived from two Greek words ''kalyx'' or ''kalux'', "cup", and ''stege'', "a covering", meaning "a covering cup",<ref> [https://www.merriam-webster.com/dictionary/Calystegia].: Merriam-Webster dictionary:Calystegia] </ref> this refers to the large bracts that cover the sepals.<ref name=Readers>{{cite book |year=1981 |title=Reader's Digest Field Guide to the Wild Flowers of Britain |page=251 |publisher=[[Reader's Digest]] |isbn=978-0-276-00217-5}}</ref>
