Raceme when the fruit is mature equal to or shorter than 
the rest of the stem. Style considerably longer than the pro- 
jecting apical lobes of the broad wings, which are separated by 
a shallow triangular sinus. 
On limestone rocks at Malham, near Settle, Yorkshire, and at 
Llanrwst, North Wales. 
England. Biennial or Perennial. Summer. 
Usually a much smaller plant than the last, the stems rarely 
exceeding 6 or 10 inches, and branched higher up; the petals 
shorter, not above twice as long as the sepals; the fruiting raceme 
not exceeding 2 to 4 inches long; the pedicels closer together, 
shorter; the pod with a more shallow sinus at the apex, and a 
style which is considerably longer than in T. sylvestre. 
The embryo in this plant has the radicle sometimes lying on the 
back of one of the cotyledons, instead of along their edges on one 
side, as is usually the case—one instance among many of the small 
value of this character among the Cruciferee. 
Long-styled Alpine Penny Cress.

Raceme when the fruit is mature equal to or shorter than the 
rest of the stem. Style much longer than the scarcely projecting 
lobes of the narrow wing, which are so little produced that the apex 
of the fruit is merely emarginate. 
On limestone rocks at Matlock Bath, Derbyshire. 
England. Perennial. Early Summer.
