簡介 |
同屬植物有時不易分辨,白背葉和白楸是好例子,兩種植物均是大戟科本地原生小樹,葉形相似,葉背白色,較仔細看,白背葉背面較白,而白楸葉背白中帶淡啡色,分佈上白背葉較少,逸夫書院路邊見一小株,校園內以白楸較常見,花果期相同。 Species from the same genus are sometimes difficult to differentiate. This is the case for the White-back Leaf Mallotus and Turn-in-the-Wind. Both are native trees of the Euphorbiaceae family, with similar leaf shape and a white underside. When examined in detail however, we see that the former has a whiter underside while the latter carries some light brown on its white underside. White-back Leaf Mallotus is rather scarcely distributed. One can be seen on the way to Shaw College. Turn-in-the-Wind is otherwise more common on campus. The two plants flower and fruit at the same time. |
