much information, and a fasciculus of specimens, and tells 
me he now thinks that some regard should perhaps 
have been paid to the variations of the root-leaves. Mr. 
Hobkirk’s descriptions are full and clear, but as he remarks 
that he does not find his specimens to agree precisely with 
the diagnoses of M. Jordan, so I find that my Leicestershire 
specimens do not quite tally with the descriptions in Mr. 
Hobkirk’s memoir. This seems to be a further indication that 
these “forms ” are of a temporary and uncertain character, 
much influenced by local conditions. 
Taking into account both the leaves and capsules, I find 
among a considerable number of specimens collected in this 
county the following extreme forms sufficiently distinguish¬ 
able, while the rest run in between them with a complexity 
of cross characters forming a confused network which defies 
classification. 
Section A.— Radical Leaves mostly Lyrate or 
PlNNATIFID. 
Var. 1.— Gracilis. Radical leaves rather thin, toothed, lyrate 
or pinnatifid, capsule small, obovate, notch none. 
Var. 2.— DensifoLia. Radical leaves firm, short, closely pin¬ 
natifid in a dense rosette, capsule forming nearly 
an equilateral triangle, notch shallow, lateral 
margins convex. On walls and in dry places. 
Var. 8. —Steyiocarpa lyrata. Radical leaves thin, toothed or 
lyrate, capsule long, narrow, obovate, notch 
moderate, lateral margins convex, lobes not diver¬ 
gent. 
Var. 4. —Stenocarpa cor onopifalia. Radical leaves thin, pinna¬ 
tifid, pinnas acute with the front margins toothed, 
capsule long, narrow, obovate, notch moderate, 
lateral margins convex, lobes not divergent. 
Var. 5.— Brachycarpa. Radical leaves rather firm, toothed 
lyrate or pinnatifid, capsule forming an equilateral 
triangle, notch shallow, lateral margins straight. 
This may perhaps be the typical form. 
Section B. —Radical Leaves mostly Entire or Toothed, 
rarely Pinnatifid. 
Var. 6 . — Rubellaformis. Radical leaves rather firm, entire or 
toothed, capsule forming an isosceles triangle, 
notch moderate, lateral margins concave, giving to 
the lobes a slightly recurved appearance. In the 
true rubella the recurved character of the lobes is 
more distinctlv marked.
