The history of the hybrids grown during this period is inter- 

 esting. In 1874 the first artificial hybrid was produced and 

 exhibited by Dr. Moore at the International Botanical Congress 

 in Florence. An abstract of Dr. Moore's paper upon the pre- 

 sentation of the hybrid is given in the Gardeners' Chronicle 

 1874, p. 738. Of the plant, which had S. flava as the female 

 and S. Drummondii as the male parent, he writes: "The plant 

 is as nearly as possible intermediate between those two noble 

 species of the genus, and no hybrid which has hitherto come 

 under my notice proves more decidedly than it does the marked 

 influence of the pollen of one plant applied to the stigma of 

 another. . . . During the months of April and May most of 

 the species flower and produce young leaves, after perfecting 

 which the plants rest six weeks or more, when some of the kinds 

 produce a second crop of leaves which remain fresh during 

 the winter and are more beautiful than those of the first crop. 

 This is especially the case with S. Drummondii. . . . S. flava 

 does not make a second growth of leaves in so marked a manner, 

 but rather inclines to rest during the winter months." "Now 

 it is in the mixture of the leaves that the intermediate state 

 of the hybrid is so strikingly exemplified. It makes a second
