extreme forms of this plant, I cannot but agree with Bertoloni 

 ( c Fl. Ital.' ii. 705) in considering the above as only varieties 

 of one species. 



D. Antherine spurs filiform, stipules* palmate-pinnatifid, stems evi- 

 dent. 



5. V. lutea (Huds.). Cells of the anthers nearly parallel ; spurs 

 elongated, filiform, spur of the corolla as long or longer than the 

 calycine appendages ; sepals acute ; leaves crenate-serrate, lower 

 ones ovate-cordate, upper ovate or lanceolate ; stipules palmate- 

 pinnatifid, the terminal lohe linear or linear-lanceolate, entire ; 

 stems ascending. PL VII. fig. 5.—Eng. Bot. 721. Reich, f. 4519. 



Flowers wholly yellow, yellow with the two upper petals purple, or 

 wholly purple, varying greatly in size ; capsule globose. — 1/ . June, 

 July ; common in mountainous pastures. 



Distinguished from V. tricolor by its stipules, which have 

 all their lobes of nearly equal size, the lateral ones (usually 

 one, sometimes two on the side next the stem, and three on 

 the other) all springing from near the base of the stipule and 

 the terminal one, which is sometimes considerably larger than 

 the others, narrow, and always quite entire. V.Curtisii(Forst.), 

 6 Eng. Bot/ 2693, appears to me to differ from this only in the 

 lower part of the stipules being more elongated, so as to se- 

 parate the lateral lobes and give them a more pinnatifid form. 

 In V. grandiflora (Linn. !), to which this has been sometimes 

 referred, the spur is twice as long, the corolla much larger, 

 and the sepals bluntish, as in V. calcarata ; and in the speci- 

 mens contained in Sir J. E. Smith's Herbarium, and called by 

 him V. grandiflora, the stipules are remarkably large, with five 

 acute narrow lobes close to the base on the outside, and a 

 single similar one near the top of that side ; on the inner side 

 the lower half is without any lobes, but there are two acute 

 lobes in _ the upper half, the terminal lobe not being larger 

 than the others. One of the specimens has very peculiar sti- 

 pules, extremely long and narrow, with three small narrow 

 acute lobes externally at the base, and one rather larger at 

 about the middle of the inner side. The late lamented Prof. 

 Don was disposed to consider V. grandiflora (Linn.) as a form 

 of V. calcarata (Linn.). The V. grandiflora (Vill.), of which 

 I possess specimens from the original locality, namely, the 

 Vosges Mountains (gathered and named by Schultz), is iden- 

 tical with the V. lutea (Sm.) and V. grandiflora (Huds.) from 

 the Clova mountains ; and although the Scottish specimens 

 have usually smaller flowers, still in one or two of them the 



• The stipules on or about the middle of the stem should always be ex- 

 amined in determining the species of Viola.
