XXXVII. 1.) illustrates its structure perfectly. It 

 has small, alternate, succulent, blunt leaves, between 

 linear and oblong. Its flowers are white, and arranged 

 in a compact cyme. The calyx {jig. 5.) is an olive- 

 green, fleshy cup, delicately streaked with crimson, 

 and divided into five, blunt, shallow lobes. The petals 

 also are five, white, spreading, narrow, and sharp- 

 pointed {fi(j. 2). Within these, from below the car- 

 pels, grow ten stamens, of which half are opposite the 

 petals, and the other half opposite the lobes of the 

 calyx. At the foot of each carpel {fig. 3.) there is a 

 minute, yellow, flat, stalked gland, the end of which seems 

 as if cut off (fig. 4.). The carpels have no adhesion to 

 each other, are five in number, and stand opposite 

 the petals, with which they agree in colour, size, and 

 very much even in shape, except that they are rolled 

 up, and taper much more to a point. The fruit is only 

 a slight change from the flower ; the calyx and petals 

 have lost their brillancy, are shrivelled and hang down 

 {fig. 70' ^^® stamens are gone, and the carpels have 

 assumed a pale brown hue ; they open at their inner 

 edge {fig. 8.), and expose the seeds, which are small, 

 smooth, and oval, and hang from their edges in a single 

 row, upon short curved stalks {fig. Q.)* The embryo 

 {fig. 11.) is white, fleshy, and taper, and is tightly 

 fitted by the seed-skin, its radicle pointing to the 

 stalk of the seed. 



The differences that mark the other British genera of 

 the Stonecrop Tribe are easy enough to remember. TiLlcea 

 consists of minute moss-like plants, having only three 

 or four petals and stamens, and no scales at the foot of
