BETWEEN DIANTHUS AND EPILOBIUM 99 
Not very far from Arenaria is Moehringia, a very 
curious species from shady alpine woods. ‘There are 
several Moehringias, but only with minute differences. 
They all make a filmy cloud of fine foliage, starred with 
small whity-green flowers. All must have shade and 
moisture, and are interesting if not very thrilling. 
Tunica Saxifraga is a most pleasant treasure from the 
south, who proves quite hardy and vigorous in this 
climate, even in open beds—though, of course he is safer 
on the rock-work, where his neck is safe from excessive 
damp in winter. I have found him all along the eastern 
and western Riviera, growing, for instance, among grass 
and rocks near the lighthouse above Antibes, in face 
of that most glorious view in Europe—which, over the 
sea, and over the little, unchanged Greek city, and over 
all the intervening ranges, has the whole splendour of the 
Maritime Alps unrolled from end to end, from crown to 
base, from the Argentera to the last peaks beyond the 
Col de Tenda. In cultivation Tunica makes a wide 
cloud of airy green, richly galaxied with innumerable 
rosy-pink stars all through the season and far on into 
autumn. Sometimes he is even a little inclined to 
overflower himself and die—but how different, morally, 
is this excessive generosity, from the greed of vulgar 
display that dictates the same conduct in the semi- 
double Mule-Pinks! And Tunica, too, sets abundant 
seed, so there is neither reason nor excuse why any one 
should ever be without him. All he wants is full 
exposure and good root-room. Then he will be a per- 
ennial joy. 
And now a sudden burst of candour compels me to 
burst back upon my own track and make mention of the 
Milkworts. On the principle that if you have nothing 
pleasant to say you should hold your tongue, I had 
allowed myself to pass the Milkworts over in a tactful
