Rochelia laxa I. M. Johnst.（紫草科）之選定模式的指定及消失四十年後模式產地的再採集

Lectotypification and Recollection of Rochelia laxa I. M. Johnst. (Boraginaceae) from Type Locality after the Lapse of Forty Years

本篇論文指定Rochelia laxa I.M. Johnst的選定模式。在該種的模式標本消失之後這是必要的，並且用以解決當前植物名稱使用的問題。此外，本篇論文也同時報導這個物種於消失四十年後又在其模式的採集地再次被紀錄到。

A note on lectotypification of Rochelia laxa I.M. Johnst. is presented in this paper. This is necessary in order to fix the current usage of the name since the holotype sheet is found to be missing. Consequently, this taxon is also recorded from the type locality after a gap of forty years since its type collection.
