FLORA AND SVLVA 
but when this is avoided they make good 
progress and reach a fair size in three 
years. We have /Sarracenm purpurea 
and S. flava of the wild kinds, and the 
hybrid S. Chelsonii^ a very pretty and 
distinct red one raised at Chelsea. Two 
kinds of Drosera, rotimdifolia and longi- 
folia^ are also growing freely with these 
Pitcher-plants. 
To establish these plants in the open 
a warm nook should be chosen, shel- 
tered from wind, and if possible with 
a trickle of water — as in this case — 
oozing from the hillside. It must not 
be too much or the plants may get 
washed away, nor should it fail in dry 
weather or the plants will soon perish. 
From this it will be seen that no hap- 
hazard spot will suffice, but that art 
and nature must combine in this as in 
many similar instances. In preparing 
the ground, take off the turf and lay it 
grass downwards, then get some good 
peat and sphagnum moss which should 
be chopped up in equal parts and spread 
upon the turfy foundations. The plants 
are put out in this prepared compost 
and fixed with further peat and sphag- 
num moss, and the whole slightly shaded 
till growth has commenced. There are 
six beds here prepared in this way, the 
largest of which contains many fine 
plants each carrying dozens of pit- 
chers, and measures 15 yards by 9. 
Others are planted in the aquatic por- 
tion of the alpine garden, but these do 
not thrive so well. Mice are great ene- 
mies of these plants and should be care- 
fully trapped. W. A. COOK.

i THE REGELIO-CYCLUS IRIS 
AND THEIR CULTURE.* 
I One of the problems which most lovers 
I of hardy plants have tried to solve, is 
the successful culture of the Oncocyclus 
\ Irises^ and it is a strange fact that, spite 
of many disappointments with these 
plants, any one who has once seen their 
glorious flowers in perfection,tries again 
and again to find means that may lead 
to their doing well. In view of the many 
notes that appear concerning them one 
would be inclined to believe that we 
were already in the way to success ; yet, 
although nobody who has studied these 
plants can deny that we have become 
I more familiar with their wants, every 
spring that comes round shows that all 
the difficulties are not yet overcome. 
Their near allies, the Regelia Iris — 
among which Iris Korolkowi and vaga 
are perhaps the best known — in some 
degree make up for the disappointment 
which their relatives too often give us, 
and when we see the ease with which 
they grow and flower, we can but hope 
for the day that will also bring the 
Cushion Iris within the reach of all. 
As an enthusiastic lover of this group 
I may claim to have tried every possible 
method of meeting their wants , and have 
been successful in so far as to have at 
last succeeded in raising a race possess- 
ing the vigour that we wish for in the 
0;2C^?(7<:///jgroup,as well as their glorious 
flowers. This new group, which I have 
called Regelio-cyclus Iris, is the outcome 
of crossing plants of the Regelia group 
— Iris Korolkowi and its varieties, /.
