Bacopa Australis 巴西虎耳

Bacopa australis was discovered in southern Brazil (australis = southern), and it does not come from Australia, as might otherwise be assumed from its name. Stems become 10-30 cm tall and 2-4 cm wide. Like the other Bacopa species, Bacopa australis is also easy to grow in an aquarium. Under certain conditions it creeps across the bottom to form an elegantly decorative light green cushion. When Bacopa australis grows in a good light, the leaves become reddish. It is easily propagated by taking side shoots and planting them in the substrate.

巴西虎耳草，双子叶植物，挺水性水草。这种水草的学名以澳洲（Australis）来命名，在一般人的观念中，理所当然会认为它应该是产自澳洲，可是它却产自南美巴西，其实australis一语，在葡萄牙（巴西）语系中是指南方（southern）之意。它的水上草具有十字对生的心型至圆形叶，深绿色，叶幅不到1㎝，喜欢在湿地匍匐生长。它也很容易在水中培养，水中叶较大，呈卵形至椭圆形，叶色黄绿，但在强光下栽培，偏上方的叶片（尤其是顶叶）可能泛红。种植疏一些，它可以在底床爬行生长，并形成一片浅绿色的地毯，相当优美。如果不适时加以修剪，它就会矗立生长，变成一大丛，也且具有装饰性。栽培相当容易，生长也颇为快速，是标准的入门水草之一。
