大乔木,高28米,树干挺直;树皮光滑,灰白色,大片状脱落。幼态叶片披针形,有腺毛,基部圆形,叶柄盾状着生;成熟叶片狭披针形,宽约1厘米,长10-15厘米,稍弯曲,两面有黑腺点,揉之有浓厚的柠檬气味;过渡性叶阔披针形,宽3-4厘米,长15-18厘米;叶柄长1.5-2厘米。圆锥花序腋生;花梗长3-4毫米,有2棱;花蕾长倒卵形,长6-7毫米;萼管长5毫米,上部宽4毫米;帽状体长1.5毫米,比萼管稍宽,先端圆,有1小尖突;雄蕊长6-7毫米,排成2列,花药椭圆形,背部着生,药室平行。蒴果壶形,长1-1.2厘米,宽8-10毫米,果瓣藏于萼管内。花期4-9月。
原产地在澳大利亚东部及东北部无霜冻的海岸地带,最高海拔分布为600米,年降水量为600-1000毫米,喜肥沃壤土。目前广东、广西及福建南部有栽种,尤以广东最常见,多作行道树,喜湿热和肥沃土壤;能耐轻霜,在广东北部及福建生长良好。木材纹理较直,易加工,质稍脆,伐后经水浸渍,能提高抗虫害蛀食;用于造船;耐海水浸渍,能防止船蛆附蚀,是造船的好木材;叶可蒸提按油,供香料用,枝叶含油量为0.8%,大部分为柠檬醛,还有少量醋和醇类,原油比重在15℃时为0.864,折光指数在20℃时为1.4594。
