148 GENERAL REVIEW OF THE OKCHIDEJi:. 



insigne x C. venustum flowered two years later. Both hybrids are 

 quite intermediate iu character. 



In the spring- of 1874 Dendrohium x Ainsworlhii flowered for the 

 first time in Dr. Ainsworth's collection at Lower Broughton, near 

 Manchester. It was obtained by Mitchell, Dr. Ainsworth's gardener, 

 from D. aureum x D. nohile. Plants from the same cross were, 

 however, raised by West about the same time at the Fairfield 

 Nursery, near Manchester. Mitchell subsequently raised Cattleya x 

 Mitclielli from G. guttata Leopoldi x 0. labiata Triance; the plant is 

 said to have been thirteen years old when it flowered for the first 

 time ; also Gyprqicdlum x Ainsworthii , a secondary hybrid with C. x 

 Scdenii for one parent. 



Two more hybrids shortly afterwards appeared in Manchester but 

 raised by another operator, these were Ci/prijiedium x Swanianum 

 and Dendrohium x Leechianum, obtained by Swan, Gardener to Mr. 

 Leech, of Fallowfield ; the last named from the reverse cross of that 

 which produced D. x Ainsworthii, and so closely resembling it that 

 it can only be regarded as a variety of it. 



Between 1876 and 1887 appeared a series of hybrid Cypripedes raised 

 by the late Mr. J. C. Bowring, of Forest Farm, Windsor, of which 

 Gypripedium x concliDtum and G. x gemmiferum are Eucypripedia and 

 G. X conchiferum and G. x stenophyllum are Selenipedia. He subse- 

 quently raised several others, some of them from the same pairs of 

 species as previously obtained by other operators. In the same epoch 

 was brought to light a batch of seedlings whose origin is not certainly 

 known, raised by Mr. Robert Warner, of Broomfield, near Chelmsford. 

 From their marked resemblance to each other and all possessing charac- 

 ters of G. venustum they may be assumed to have resulted from one 

 cross in which G. venustum participated ; they were named by 

 Eeichenbach G. x discolor, C. x chloroneurum, G. x poliium, G. x Meirax 

 and G. x melanophthalmuni. Later from the same source appeared 

 another batch from a different parentage and named G. x Williamsi- 

 anuni, G. x Amesianum and G. x Measuresianum. C. x villosum and 

 G. venustum participated in the parentage of all these; in G. x 

 Williamsianum G. villosum participated, mediately probably through 

 G. X Harrisianum. Following close upon Mr. Bowring's earlier pro- 

 ductions have appeared a long series of Cypripedes raised by Mr. 

 D. 0. Drewett, of Riding-Mill-on-Tyne, of which fifteen or more
