本研究以解剖顯微鏡和掃瞄式電子顯微鏡 ( SEM ) 觀察台灣產野牡丹科 11 屬 22種種子之外部形態與種皮紋飾。研究結果顯示：種子大小在屬間有差異，其中以革葉羊角扭的種子最大。根據種子形狀，將種子外形分為 8 個類型，線形披針形、楔形、紡錘形、腎形、蝸牛殼形、倒卵形、近三角形和平行四邊形，除肉穗野牡丹屬以外，種子外部形態在屬下頗為一致；種皮紋飾分為 6個類型，分別為多突疣、皺紋、平滑、瘤狀、小顆粒狀和圓丘狀。種子顏色分為蛋黃、褐、深褐和紅褐。野牡丹科屬間種子長寬及外形差異大，種間則需以種皮紋飾細部差異作為區分的依據。

The seed external morphology and seed coat pattern of 11 genera and 22 species of Melastomataceae in Taiwan were studied by dissecting microscopey and scanning electron microscopey. According to the seed size, the result showed that the length and width of seed is different inter-generically. The biggest size is the seed of Memecylon while contrast to those of the other genera. The seed shapes could be divided into 8 types. They are liner-lanceolate, cuneate, fusiform, reniform, cochleate, triangular, obovoid and parallelogram respectively. Except that of the Sarcopyramis, the seed shape is rather stable intra-generically. The seed coat could be classified into 6 patterns. They are verrucate, rugose, smooth, tuberculate, granulate, and colliculate respectively. The seed colors are egg-yellow, brown, nut-brown and reddish brown. The difference of seed morphology is obvious inter-generically, and the difference of seed coat patterns is extinctive intra-generically.
