none; clawed; limb obovate, rounded at tbe apex. Stamens 
usually 4. Ovary linear: style very short: stigma bearded 
with minute papillary hairs. Silique nearly an inch in length, 
erect, subterete, 'compressed, glabrous, opening elastically, with 
the valves revolute towards the apex : seeds orbiculate, light-

I have no doubt but that this is the C. Sylvatica of authors, 
said to be common throughout Europe. It has probably been 
introduced by accident into this country. It is a very common 
plant in our mountain districts. The elasticity of the valves of 
the pods is very distinct, and the seeds are projected by means 
of it to a considerable distance.

FL. ? 
This plant has long been introduced into the Island. It is, 
when once established in a garden, with difficulty eradicated, d 
have never observed it in flower. Lunan however remarks that 
“ it blossoms and seeds luxuriantly.”* The root is long and 
runs deep in the ground ; it has a pungent flavour, is supposed 
to favour digestion, and is well known at our tables as a condi- 
ment : being a strong stimulant, it acts externally as a rubefa- 
cient : and a syrupf is prepared from it, which is peculiarly 
useful in hoarseness, and recent sore throats.
