and T. minus. 



W 



sent me a series of specimens, some of which were T. collinum 

 Wallr., some T. odoratum, and one was a near approach to T. fceti- 

 dum ; but I am not sure of the latter for Britain yet. : 



Ranunculus Baudotii X Drouettii, R. Baudotii X heterophyllus, 

 R. peltatus X trichophyllus, and R. peltatus X Lenovmandi are given 

 by Messrs, H. & J. Groves in Bab. Man. ed. ix. ; and the last- 

 named is said to be partially fertile (Jouni. Bot. 1901, 121). 



Papaverace^. — Papaver dubium x Rhceas was once issued by 

 Mr. G. Nicholson, if I remember rightly, the name being based on 

 the shape of the capsule mainly. I remember seeing P. Rhceas 

 forms with similar intermediate capsules in Norfolk, but did not 

 arrive at any conclusion. 



FuMARiACEiE. — Fumaria demiflora x officinalis is reported (p. 120) 



by Mr. C. E. Salmon from near Wendover, Bucks, who says the 

 plants were apparently quite barren, as well as intermediate in 

 character. 



CRUCiFERiE. — Cardamine pratensis X flexuosa was reported from 

 between Kew and Mortlake by Mr. George Nicholson, and issued 

 through the Botanical Exchange Club (Rept. 1879, p. o) as var. 

 Hayneana Welw. A similar plant was found in Shapwick by Rev. 

 W. E. Linton, which we regarded as this hybrid without any doubt. 

 On growing a root at Bournemouth for two seasons, it proved per- 

 fectly sterile. 



Cochlear ia. Mr. Marshall once reported a hybrid from his 



garden at Milford, but he tells me he is not sure that any have 

 occurred wild.

Violace^e.— Viola hirta X odorata, local, but not very rare; 

 according to my experience, sterile ; Rouy & Foucaud say, sterile 

 or with 2-6 seeds. — V. silvestris x Riviniana has been detected by 

 the Rev. W. R. Linton at Shirley in the garden and neighbourhood, 

 and is sterile. — V. Riviniana x ericetorum^ more widely distributed 

 than the last. I have met with it three times at least in Dorset ; 

 always sterile. — V. ericetorum x lactea was sterile near Bourne- 

 mouth, and probably elsewhere. — V. ericetorum x stagnina was, I 

 believe, sterile on Holme Fen. To these, Mr. Marshall tells me, 



may be added V.

 W. Gloster!' Dr. Focke 



Bays this hybrid ( T. lancifolia Thore X Riviniana Rchb.) is alleged 

 to have been observed in France. — V. arvensis x tricolor, which I 

 have put on record for Dorset, produced what looked like good seed 

 and capsules well-formed ; it is doubtful whether there is specific 

 difference between these. I have also seen in Dorset both V. arvensis 

 (Baileygate) and V. tricolor form (Blandford) crossed by some 

 garden pansy. 



Caryophyllace^:. — Silene. Darwin (Origin of Species) says that, 



while several hybrids have been made between species of Dianthus,
