TIOLA 77 



V. Riviniana exliibits considerable variation in the size of its flowers 

 and in the sLap^e of its petals. The spxir, which is normaUv pale, is 

 sometimes found of varying shades of blue. The furrow in the ^mr 

 also varies in distinctness, but I have not found great diffieoltr in 

 separating V. ^restrls from it. The hybrid of the two species, which 

 was found in company with t«th of the assumed parents near Basil- 

 don, was a very free-flowering plant. 



r. Riviniana is sometimes found with more or less p«ibMe«iee on 

 the petioles, peduncles, and leaves 'rar. vtli/^sa, Neum. Wahlst. and 

 Murb.), but it scarxsely seoas worthy of varietal rank. A very large- 

 flowered plant with a darker-coloured spur, which blosisoins later in 

 the sea5<:»n. appears to be the var. kemoB'^sa of the same authors. 

 The much longer f«etal5 give it a quite difft- rent appearance from the 

 normal roxmd-flowered Y. Rivmiatta. It is usually a little more purple 

 in tint. I have seen it at ITffingU.n on the Upper Greensand and in 

 other localities. The leaves of this species are sometimes dark pur- 

 plish-brown (/. cuprea . This form occurs more frequently on sunny 

 heathy spots.
