2(j THALAMIFLORA:. 



none clawed ; limb obovate, rounded at the apex. Stamens 

 usually 4. Ovary linear: style very short: stigma bearded 

 with minute papillary hairs. Silique nearly an inch in length, 

 erect, subterete,>ompresspd, glabrous, opening elastically, with 

 the valves revolute towards the apex : seeds orbiculate, light- 

 ferruginous. 



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 varves of 

 the pods is very distinct, and the seeds are projected by means 

 of it to a considerable distance. 



III. COCHLEARIA. Scurvy-grass. 

 Pouch oval or globose, many-seeded, with the valves 



turgid. Filaments simple. Seeds not margined. 

 Calyx patent. Cotyledons accumbent, (O = ). 

 Brown. 



Name, from the leaves resembling a spoon (COCHLEAB) in 

 shape. 



1. Cochlearia Armoracia. Horse-radish. 

 Pouch oblong, stigma dilated nearly sessile, radical 

 leaves oblong on long footstalks crenate, cauline ones 

 elongate-lanceolate serrate or entire. Hooker.

This plant has long been introduced into the Island. It is, 

 when once established in a garden, with difficulty eradicated. I 

 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.
