copiously bracteate peduncles of the latter plant. 
Herbarium material of S. glastifolius shows that there is 
considerable variation in the shape, texture and toothing 
of the leaves. These changes of appearance, waich may 
be due to the conditions under which the plants have 
grown, leave the flower-heads remarkably uniform and 
unmistakable on account of the numerous exterior supple- 
mentary bracts. From a remark in the note which 
accompanies a full-page illustration of the species in the 
Gardeners’ Chronicle for 1910, it would appear that 
S. glastifolius was raised by Messrs. Sutton and Sons 
from seeds received by them from the district of George, 
immediately to the east of Riversdale. The plant from 
which the figure here given has been prepared was pre- 
sented to Kew in 1913 by Mr. H. Rabjohn, Twickel, 
Delden, Holland, and flowered in a greenhouse in April, 
1914, It is a perennial, is easily propagated by cuttings 
and grows into an elegant upright plant, about four fect 
in height, flowering during April and May. It does well 
if given conservatory treatment and grown along with 
greenhouse Cinerarias,. but it may be noted that Mr. 
‘Rabjohn, in the Gardeners’ Chronicle, writing from 
Welbeck Abbey, Worksop, in 1910, has described it as 
being vigorous in an open border, resisting successfully 
ten degrees of frost, though succumbing when the 
thermometer fell to 15°.
