OGcidentalis (Rouy as a race), which is the plant of Western France." 

 — G. C. Druce. " No properly developed fruit but the species is of 

 course unmistakable. It apparently requires still water to fruit at all 

 freely." — J. Groves. 



Epilohium hirsutum, L., 5 x ^- montanum^ L., ^. Artificial 

 hybrid, produced in July 1909 by emasculating flowers of E. 

 hirsutum, L., and pollinating from E. montanum, L., insects 

 being excluded by means of paper bags. Both parents were 

 grown under observation in a garden at Tewkesbury, in which also the 

 hybrid has been cultivated, 1910-12. During these three seasons the 

 plant has varied somewhat in vegetative characters, but the speci- 

 mens distributed represent the most abundant form. Long runners 

 are not produced, the plant being propagated by close-growing rosettes. 

 Another character of E. hirsutum, viz., the possession of long simple 

 hairs, is also recessive in the hybrid (compare E. hirsutum x E. 

 tetragonum, distributed 1910). No perfect flowers are ever produced, 

 the nearest approach being a single bud which protruded a four-lobed 

 stigma in 1912. Most of the flowers remain minute, and dry up with- 

 out opening ; ovary, sepals, stamens, style and stigmas, are all present 

 in a rudimentary condition. This is the most extreme case of sterility 

 that has so far been observed in an Epilohium hybrid. It is clear that 

 the first generation hybrid is the only one that can exist. — R. H. 

 CoMPTON. " Here the general appearance and foliage show good 

 evidence of both parents ; the flowers are small and deformed, as I 

 have frequently observed in natural garden hybrids. The few wild 

 examples of this cross that I have seen have large, showy petals." — E. 

 S. Marshall. 



Epilohium hirsutum, L., 9 x E. parviflorum, Schreb., ^. Artificial 

 hybrid, made 1911, Tewkesbury, July 1912. This artificial 

 hybrid was produced in 1911, both parents as well as the 

 hybrid being grown in a Tewkesbury garden. The plants 

 have the type of clothing found in E. parviflorum, viz., long 

 simple hairs throughout, mixed with shorter clavate hairs in the 

 inflorescence. There are no long runners such as E. hirsutum possesses. 

 The flowers are somewhat smaller than those of E. hirsutum, but have 

 the petals coloured as in that parent. The pollen is abortive, but the 

 ovules are (at least in part) capable of fertilisation, so that insect 

 visits produce some capsules containing a few good seeds ; and seed is 

 set on pollination from either parent. — R. H. Compton. "Just like 

 wild specimens. Though the species are so often associated, I have 

 seldom found this hybrid." — E. S. Marshall.
