37 2 GENERAL REVIEW. 



from L. auratum in our own day. It is the more remarkable 

 to find that Mr Groom grew his L. speciosum varieties in the 

 open air, and so obtained results but rarely equalled by green- 

 house or pot culture. In 1850, we find Messrs E. G. Hender- 

 son & Sons had a houseful of the seminal varieties of L. 

 speciosum. 



In the 'American Gardeners' Monthly,' 1868, Mr Wilder 

 records some of his experiments in crossing Japanese Lilies. 

 He asserts that he has crossed L. landfolium with the pollen 

 of L. tigrinum ; and he remarks that Z. auratum is fertilised 

 with difficulty by its own pollen, or with that of L. tigrinum, 

 while it is quite possible with pollen of L. landfolium. 



The Prussian botanist, Maximowicz, also obtained inter- 

 mediate forms between L. davuricum and L. bulbiferum his 

 object, however, being rather to observe certain points in the 

 action of foreign pollen than to obtain beautiful new forms of 

 garden plants. An account of his experiments may be found 

 in 'Jour. Royal Hort. Soc.,' vol. iii. (New Series), p. 161. 



In the gardens of China, and especially in Japan, are 

 innumerable beautiful seedling varieties, some of which have 

 been introduced to this country, apparently in many cases 

 hybrids between L. auratum, L. spetiosum, and L. longiftorum. 

 Lilium Parkmannii is a large and beautiful hybrid raised by 

 Mr Parkman, an American cultivator, and by him sent to Mr 

 Waterer of Knaphill. The entire plant is 2-3 feet in height, 

 its stem being clothed with alternate ovate-nerved leaves, and 

 each bearing one erect flower fully 8 inches across as reflexed, 

 the total width with the segments stretched out being 13^ 

 inches. The three inner segments are fully 4 inches in width. 

 The segments are white, their lower halves being suffused with 

 rose, and studded with deep crimson spots and papillae. The 

 style is green, and the pollen chocolate-coloured. This fine 

 plant is the result of a cross between L. auratum and L. 

 spetiosum (see 'Gardeners' Chronicle,' 1875, p. 237, 366, 

 and 494, with full-sized woodcut figure). 



Several other hybrids have been raised in English gardens 

 between L. auratum and L. speciosum, one of which, a very 

 chaste and beautiful variety, named Z. " Purity," was exhibited 

 by the raiser, Mr G. Thomson, at South Kensington in 1870. 



Z. testaceum is supposed to be a hybrid, and its history may 

 be found in ' Flore des Serres,' vol. i., its assumed parents being 

 Z. candidum and L. chalcedonicum. 



Z. (hybridum) Kramerii is a handsome Japanese plant, by 

 some supposed to be a hybrid between Z. speciosum and Z. 

 japonicum (see 'Flore des Serres,' 1874, p. 31, t. 2061-62):
