Family of flowering plants
Boraginaceae , theborage orforget-me-not family , includes about 2,000 species ofshrubs ,trees , andherbs in 146[ 3] to 154genera with a worldwide distribution.[ 4]
TheAPG IV system from 2016 classifies the Boraginaceae as single family of the orderBoraginales within theasterids .[ 5] Under the olderCronquist system , it was included in the Lamiales, but clearly is no more similar to the other families in this order than it is to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae into 11 distinct families:[ 6] Boraginaceaesensu stricto , Codonaceae,Coldeniaceae ,Cordiaceae ,Ehretiaceae ,Heliotropiaceae ,Hoplestigmataceae ,Hydrophyllaceae ,Lennoaceae ,Namaceae , and Wellstediaceae.
These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some havepetioles . Most species have bisexual flowers, but some taxa aredioecious . Mostpollination is byhymenopterans , such asbees . Most species haveinflorescences that have a coiling shape, at least when new, called scorpioid cymes.[ 7] The flower has a usually five-lobedcalyx . The corolla varies in shape from rotate to bell-shaped to tubular, but it generally has five lobes. It can be green, white, yellow, orange, pink, purple, or blue. There are fivestamens and onestyle with one or two stigmas. The fruit is adrupe , sometimes fleshy.[ 8]
Most members of this family have hairy leaves. The coarse character of the hairs is due tocystoliths ofsilicon dioxide andcalcium carbonate . These hairs can induce an adverse skin reaction, including itching and rash in some individuals, particularly among people who handle the plants regularly, such as gardeners. In some species,anthocyanins cause the flowers to change color from red to blue with age. This may be a signal topollinators that a flower is old and depleted ofpollen andnectar .[ 9]
Well-known members of the family include:
