was added to the synonymy of S. scandens by Klatt, and 
Zexmenia (Otopappus) tequilana was published by Gray from 
Palmer’s Jaliscan collection of the previous year. In 1891 
O. alternifolius was published from Mexico b i : 
the previous year Hoffmann, in the Pflanzenfamilien, following 
Gray’s hint of 1887, had sunk Otopappus to sectional ran 
under Zexmenia, an act in which he is not 
followed by anyone acquainted with the characters of the 
genera concerned. In 1891, also, Watson described S. Palmeri 
from Jalisco, and in 1892 Britton published S. mikanioides from 
Bolivia, anomalous in the genus as then constituted by reason of 
its radiate heads, although these were not referred to in the 
original characterization.
