‘appear to offer no characters to distinguish that species from 
linearifolium. The petals of trifidum are variable also though 
to a less extent, and are usually, but not always, narrower than 
those of linearifolium. Much the best character by which to 
' separate the two species is the leaves, which in trifidum are ag- 
" gregated at or near the top of the stem, and though very variable 
in shape are generally very much broader and more deeply 
toothed than those of linearifolium, in which they are scattered 
_along the stem, linear or nearly so, and entire or slightly toothed. 
On this showing, Hamet’s two varieties ought to remain under 
trifidum ; they have the leaves of that species, the sepals are 
untrustworthy, and the petals in specimens named by him are 
in some cases as narrow. ‘The two varieties besides seem rather 
close together for so variable a plant.

Hamet in Herb. Léveillé (now in Herb. Edinburgh) names 
several sheets of this plant S. leucocarpum, Franch. But I can- 
not make S. varticolor (which I have had in cultivation for some 
years) agree with Franchet’s description, particularly as regards 
the furfuraceous young leaves and stems, the fuscous coriaceous 
scales at base of the branches, and the ivory-white follicles, which 
he states to be very remarkable. My plant is quite glabrous 
and green, devoid of scales, and the fruit turns merely whitish 
when dead, as in most Sedums. I therefore retain the name 
varticolor till | have had an opportunity of examining Franchet’s
