The species of Sempervivum are by no means easily 
distinguished, and in many of the groups of the genus 
they tend to “run into one another,” as botanists express 
it, and have considerable ranges; whilst in other cases 
exceedingly distinct species occupy very restricted areas 
in the mountains of Southern Europe. ‘The subject of the 
present plate does not agree with any of the one hundred 
and four forms enumerated by Mr. Baker in the Gardeners’ 
Chronicle (1874, p. 103), and which he has wisely reduced 
to thirty-three definably distinct species in the Chronicle 
for 1879. Amongst these latter the nearest ally of 8. 
Moggridgei is clearly the well-known 8. arachnoidewm of 
Linneeus, one of the earliest plants figured in this work 
(Tab. 68), and which extends from the Pyrenees to the 
Tyrolese Alps. It differs from S. Moggridgei in the much 
shorter leaves of the rosette, which are more oblong, and 
form a rounder mass, in the oblong obtuse cauline leaves, 
and in the smaller and less numerous flowers and glabrous
