1.— THE COMMON NAVELWORT. (Umbilicus pendulinus, Dec.) 
Synonymes. —Cotyledon umbilicus, Hudson ; Wall Pennywort. | Specific Character. —Leaves peltate, notched. Flowers clustered, 
Engravings. —Eng. Bot., t. 325 ; 2nd ed., t. 648 ; and our Jig. 1, drooping. Bracteas entire. Root tuberous. {Smith.) 
in PI. 21. 
Description, &c. —This plant is very common in some parts of England, particularly in Somersetshire and 
Devonshire. It is generally found growing on old walls, or rocky banks, in moist, shady situations; as it 
appears to thrive best where it has warmth and moisture combined with shade. The stem grows from six inches 
to a foot long, and it is always of a pinkish or purplish hue. The flowers vary from a pure white to a yellowish 
green, and they appear from June till August. The leaves are extremely smooth, and of a thick, succulent 
texture ; they are round, with the footstalk proceeding from the centre, and sometimes they are almost cup¬ 
shaped. It is this last peculiarity which gave rise to the first name of the genus; the word Cotyledon being 
derived from a Greek word signifying a cup.

2, in PI. 21. 
Description, &c. —This species is so very different from the last, that it is difficult to imagine it to be the 
same genus. It has, indeed, very much the appearance of a Yerbascum. It is found upon walls and rocks in 
the West Riding of Yorkshire ; but is very rare in every other part of England. It is a perennial plant, and it 
flowers in July.

scales entire. Fruit in five parts.—Herbs with fleshy leaves, many branches, and cymose flowers. (Lindley.) 
Description, &c. —All the plants belonging to this genus are perennials, with succulent stems and leaves. 
They have nearly all very showy flowers and small roots; and they grow usually upon rocks where there is 
scarcely any earth, and hence the name of Sedum, which is derived from sedo, I sit, in allusion to the manner
