•那些是胎生苗。它的外形又尖又長，就像一支鉛筆，所以俗稱為「水筆仔」。它是最常見的紅樹，差不多全港的紅樹林內都能發現它。它可達5米高，在近岸的泥地上生長。除了五月至七月，大部分的時間都能見它的胎生苗！
•藏在胎生苗內的種子，在母樹上吸取營養，並開始發芽。至成熟後，它便脫落並嵌進軟泥裡迅速成長。這種「胎生」繁殖法在植物界中十分罕見。

•Those viviparous seedlings are called droppers.Its elongated shape, with a sharp end, looks like a Chinese brush-hence its Chinese name, "Little Water Pen". This common mangrove species is found in nearly all mangrove swamps in Hong Kong. The tree grows up to 5 m in coastal mudflats. Its droppers can be seen during most of the year, except from May to July.
•The droppers germinate and grow by obtaining nutrients from the mother tree. When ripe, they drop and penetrate into the soft mud and start growing upwards rapidly. This process is named vivipary, and is an unusual reproductive method in plants. ■資料：漁護署
