印度西孟加省之錢蘚屬（錢蘚科）植物

Riccia (Hepaticae: Ricciaceae) of West Bengal

印度西孟加省之12種錢蘚屬植物經由掃描電子顯微鏡詳細研究，其中三稀有種為本省新紀錄種包括：R. melanospora、R. perssonii及R. stricta。另外七種孢子之掃描電子顯微鏡圖包括：R. crispatula、R. cruciata、R. discolor、R. huebeneriana、R. melanospora、R. perssonii及R. plana乃首次由印度之標本呈現。本文藉由光學顯微鏡及掃描電子顯微鏡觀察後，每種都有簡短敘述，並附有掃描電子顯微鏡圖。

Twelve species of the genus Riccia L. from State of West Bengal have been studied critically under SEM. Three rare species, viz. R. melanospora, R. perssonii and R. stricta have been recorded for the first time from the State. The sporoderm of R. crispatula, R. cruciata, R. discolor, R. huebeneriana, R. melanospora, R. perssonii and R. plana from Indian materials have been studied for the first time under SEM. Brief taxonomic descriptions of each species based on observation under Light Microscope as well as Scanning Electron Microscope have been provided along with SEM micrographs.
