however, bear some resemblance to those of the fen plant, and it 

 will be borne in mind that Prof. Babington does not separate 

 typical V. lactea from the "var. intermedia.'' I have little doubt 

 myself as to the hybrid origin of this plant ; Mr. Fryer believes 

 that it is sterile, but feels some doubt as to its origin on grounds 

 connected with the relative distribution of the three forms. In a 

 paper on " Nagra Viola-hybriditeter for svenska Floran " (* Bot. 

 Notiser,' 1884, p. 144), Dr. L. J. Wahlstedt writes concerning this 

 plant to the following effect : — What most characterises its hybridity 

 and displays its hybrid origin is the bad quality of the pollen, of 

 which from 80 to 95 per cent, consists of small, empty and quite 

 useless grains. The pistil appears also to be constantly sterile, 

 whereas mature fruit is wanting. — It is interesting to find that a 

 high vegetative activity is also a characteristic of this hybrid, for 

 the following note is appended to the examples numbered 28 in the 

 Fasciculus: — "All the specimens distributed were gathered from 

 two tufts." — Hunts and Cambs., A. Fryer \ 



The plants grown at Eeigate are Viola Fdviniana, silcestris, 

 canina, and lactea; V. Fdviniana X canina and V. lactea X canina. 

 The four species seed freely in both the wild and cultivated state ; 

 the two hybrids are not known by me to have produced a single 

 seed. I hope to grow the other hybrids mentioned in this paper, 

 and also to give later the results of investigations now in progress 

 on the hirta and odorata section. Of those at present noted in 

 Surrey, two forms are, I believe, hybrids V. odorata x hirta, tending 

 respectively towards one or other parent ; one form is probably a 

 distinct subspecies of odorata; and one or two others may be 

 varieties of V. hirta. In V. Idrta and its allies the leaves are not 

 developed at flowering time, and it is absolutely necessary for 

 determination to collect also later specimens bearing full-grown 

 leaves and ripe capsules. For the proper understanding of these 

 forms it is as essential that they be collected at two different seasons 

 as it is in Potamoyeton or in Salix.

The following remarks refer to a three weeks' stay in Scotland, 

 from June 19th to July 12th of last year, with occasional references 

 to plants observed in former years. Several interesting things were 

 met with ; but, owing to the early date of my visit, the sedges were, 

 in many cases too young for satisfactory determination. Hieracia 

 were also to a large extent found in bud only ; but four or five 

 forms were secured which may perhaps prove new to this country^ 

 I may mention that three of these, from Argyleshire, are very near 

 specimens in Dr. Lindeberg's Scandinavian 'Exsiccata' of H. 

 ciesium var. alpestre, II. submiirorum, and H. saxifrayum var\ 

 nemorosum, as far as appearance goes. But specimens have not
