Ericaceae
Also known as heath family, heather family
The Ericaceae () are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most speciose family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (Erica, Cassiope, Daboecia, and Calluna for example).
AI overview
The Ericaceae, or heath and heather family, is a large group of flowering plants containing roughly 4,250 species that thrive in acidic, infertile soils and rank as the 14th most diverse flowering plant family. This family includes many plants we know well and depend on economically, such as blueberries, cranberries, rhododendrons, and azaleas.

杜鵑花科（学名：Ericaceae）為双子叶植物纲植物，约有75属1350余种，中国共有20属700余种。杜鵑花科的模式屬是歐石楠屬（Erica）。 常見杜鵑花科植物包括有杜鵑花、馬醉木、藍莓等。大多數杜鵑花科植物有毒，如羊踯躅。但部分如紅莓、藍莓、越橘等卻是常食用的果物。 目录 1 形态 2 分布 3 屬 4 外部链接 形态 多年生灌木或小喬木，偶有亚灌木状多年生草本或藤本种类。 葉形為倒披針形，单叶，上有細毛。 花两性，常辐射对称；花萼宿存；合瓣花冠，4－5裂，呈漏斗状、钟形或壶形；雄蕊从花盘基部发出，常为花冠裂片两倍，很少同数，花药具有尾状附属物，顶上孔裂至全面纵裂，花粉形成四合体；子房上位或下位，2－5室。 果实为蒴果、浆果或核果。 分布 杜鹃花科植物广布于全球温带，也产于热带山区，少数环北极分布。大多适应于气候温凉、湿润、土壤偏酸的环境，在许多具有海洋性气候的地方成片生长，构成植被的优势。多生于山地森林，有陆生和附生，很多种类分布树线以上，形成高山植被。在中国各地都有分布，但西南山區品种最多。 山月桂（Kalmia latifolia）的花辐射对称。 弯果杜鹃（Rhododendron x campylocarpum）的花两侧对称。 屬 越橘属果实 Leptecophylla juniperina Chimaphila menziesii A Acrostemon 顶毛石南属 Acrotriche 树萝卜属 Agapetes 绊足花属 Agarista Allotropa 獐牙石南属 Andersonia 青姬木属 Andromeda Anomalanthus 距药莓属 Anthopteropsis 翼冠莓属 Anthopterus Arachnocalyx 浆果鹃属 Arbutus 狼毒石南属 Archeria 熊果属 Arctostaphylos 北极果属 Arctous 松石南属 Astroloma B 七瓣杜属 Bejaria 瑞香石南属 Brachyloma Bruckenthalia 线香石南属 Bryanthus 杉石南属 Budawangia C 帚石南屬 Calluna Calopteryx 岩须属 Cassiope 艳苞莓属 Cavendishia 沙石南属 Ceratiola 囊冠莓属 Ceratostema 地桂属 Chamaedaphne 喜冬草属 Chimaphila Coccosperma Coilostigma Comarostaphylis 梭花石南属 Conostephium 岩帚兰属 Corema 腺叶莓属 Costera 金叶子属 Craibiodendron 杜松石南属 Cyathodes D 大宝石南属 Daboecia 凌霄莓属 Demosthenesia 羊乳莓属 Didonica 异蕊莓属 Dimo

The Ericaceae () are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most speciose family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (Erica, Cassiope, Daboecia, and Calluna for example).
==Description== The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually radially symmetrical (actinomorphic) and urn-shaped, but many flowers of the genus Rhododendron are somewhat bilaterally symmetrical (zygomorphic). Anthers open by pores.
