Klatt, 1. c., reprint p. 8. I am indebted to Professor Eug. Warming of 
Copenhagen for a critical comparison of Mr. Pringle’s no. 5713 with 
Liebmann’s no. 192, the original of S. bracteatus, Klatt (Cacalia amplexi- 
caulis, Schz. Bip.). There can be no doubt of the identity of the two 
plants, although the Liebmann specimen is said to be rather incomplete.
