NOTES ON LILIES 



bulb with open scales, and a reduced sketch of a freshly dug speci- 

 men, in which the curved fleshy scales are closely imbricate. The 

 bulbs of this plant are extremely variable in colour^ varying from 

 white to deep purplish- crimson, especially in light porous soils. This 

 plant has been largely propagated from seeds by the Dutch growers, 

 and formerly by Mr. Groom, Messrs. Henderson & Son, and other 

 bulb cultivators in this country ; hence we find numerous minor 

 differences in growth and colour of the flowers. 



L. Auratwn. The bulbs of this variable species are as large* as, 

 and similar in colour, shape, and structure to, those of the last-named 

 plant, a fa.ct, which goes some way to prove their near alliance, 

 especially when ; we, find this more fully proved by the fact of these 

 two species having hybridised together, the beautiful ParJmanni being 

 ,th6.<J&pring ox thesa two species, as also was an earlier hybrid called 

 "Purity j certificated some years ago by the Royal Horticultural Society 



at South Kensington.

L. PMladelphicum. Mr. 

 Baker describes the bulbs 

 of this plant as " small, 

 annual, stoloniferous; scales 

 fragile, thick, nearly club- 

 shaped," and I have else- 

 where found them described 

 as being produced in a rhi- 

 zoinatous manner in their 

 Canadian and Carolinian 

 habitats ; my figure was 

 made from a specimen 

 selected from a small impor- 

 tation of fifty or one hundred 

 roots, and represents a full- 

 sized bulb ; I saw 110 traces 

 of rhizomatous growth, but 

 it is possible that they had 

 been broken up before tran- 

 sit, previous to their having 

 been counted and invoiced. 



L. Philadelpliicum (Canada and N. United States) ; 

 natural size ; from an imported bulb ; colour, 

 white or yellowish. 



* Bulbs of Auratum vary much in size and shape, generally they are of a whitish or 

 yellow colour, on exposure to air getting a pink or reddish brown tint, as compared with 

 the preceding species, the scales are more numerous, of a much closer texture, more 

 compact, more acute at the tip, and shorter as to length ; they overlap in several 

 tiers before reaching the summit of the bulb, which is flattened. In Auratum the 

 tendency is to extend its growth laterally, in Spcdosum vertically.
