Beakea(岗松属)、植物属桃金娘科,从中国大陆到澳大利亚都有广泛的分布。已经描述的约有70种,该属植物遍布在澳大利亚各个州。它们大部分为具细小分枝的直立丛生灌木。大多数该属植物能通过扦插繁殖并能在花卉稀少的冬季和早春开出迷人的小花,因而被广泛应用在园艺中。 1985年2月发现生长在澳大利亚昆士兰州的一种岗松属植物表现出典型的黄化症状。黄化植株树冠变矮,直立生长特性更明显,嫩枝及其节间变短,叶片典型黄 Beakea (Pinaceae), Myrtaceae plants, from China to Australia have a wide distribution. About 70 species have been described, and the genus is found in all Australian states. Most of them are erect tufted shrubs with small branches. Most of the genus can be widely used in horticulture because it can be cut by cutting and can produce attractive florets in rare winter and early spring flowers. In February 1985, a genus Pinus grown in Queensland, Australia, showed typical symptoms of yellowing. The canopy of etiolated plants became shorter, the erect growth characteristics were more obvious, the twigs and their internodes became shorter, and the leaves were yellow
