NOTES ON THE NEWER OR LESSER KNOWN WATER-LILIES. 299 



test. These were N. Marliacea Candida, N. Marliacea rosea, 

 N. Marliacea camea, N. Marliacea chromatella, N. odorata 

 rubra, N. odorata rosacea, N. odorata exquisila, N. odorata 

 sulplmrca, N. odorata sidphurea grandiflora, N. Laydekeri rosea, 

 N. pygmcea hclvola, 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. I 

 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
