ftOTES ON THE NEWER OR LESSER KNOWN WATER-LILIES. 299 
test. These were N. Marliacea Candida, N. Marliacea rosea, 
N. Marliacea carnea, N. Marliacea chromatella, N. odorata 
rubra, N. odorata rosacea, N. odorata exquisita, N. odorata 
sulphurea, N. odorata sulphurea grandiflora, N. Laydekeri rosea, 
N. pygmcea helvola, and N. flava. Of these I only lost the last- 
named variety, which comes from Florida ; hence it is not suf¬ 
ficiently hardy. This was in the spring (about the middle of 
April) of 1894. The winter following, which was a most severe 
one, soon afforded me a sufficient test of their hardihood, except 
in the one instance already alluded to. Our lowest record that 
winter was, I think, 26 deg. of frost; and as the Lilies, by reason 
of being small, were as yet in shallow water, the ice must have 
almost reached their crowns. The following spring the eleven 
all started into growth with increased vigour, and by the autumn 
were strong plants with occasional flowers. In the spring of 
1896, owing to the satisfactory growth during the previous year, 
I resolved to give them more room, and proceeded to lift them 
during April. To my surprise they had rooted so strongly as to 
require three pairs of hands to remove the largest ones with all 
the roots that could be secured with each stool. In the case of 
the strongest plants the roots were as large as one’s fingers, 
and they had taken a firm hold of the bottom of the lake. 1 
might mention here that when I first planted them in 
1894 I only used medium to large-sized Strawberry punnets 
in which to plant them previously to putting them into the 
water. This instance is some indication of how they will 
thrive when in congenial quarters. But very little, if any, 
check was noticeable in the growth during that spring 
(viz. 1896), and by the summer they were again rapidly 
increasing in size and vigour ; whilst, as regards flowering, there 
was a marked improvement both in their freedom and in the size 
of the individual blossoms. Since that removal I have not again 
touched these plants, save to take away a few offshoots. During 
last summer ( i.e . 1897) there was again a marked improvement 
manifest in the growth and also in the larger size of the flowers, 
as well as in their freedom in producing them. This past spring 
they all again started away very freely, and in every case 
promised well. 
I have explained the treatment as regards removal, &c., of 
these varieties ; and I might add that I shall continue to adopt
