高聳而又美觀的大喬木，由澳洲引入，本港處處均見種植，校園內最具代表的群落，見於范克簾樓，幹粗大挺拔，側枝横向伸展如輪。名為異葉，因一樹可見兩種形狀不同的小葉。花分雌雄，結圓形球果。

This tall and distinctive conifer is endemic to Northfolk Islands in the Pacific, as its vernacular name implies.  Now imported from Australia, it is commonly grown in Hong Kong.  The most representative cluster on campus lies in front of the Franklin Building.  It has a strong and straight vertical trunk and symmetrical branches that alternate to extend horizontally.  The scientific name heterophylla  ('different leaves') derives from the variation between young and mature leaves on the same plant.  Flowers meanwhile, have male and female distinctions.  Cones are spherical in shape and found mainly in the upper crown.
