A hardy herbaceous plant, with long tough slender creep- 

 ing stems from which the leaves spring upon stalks about six 

 inches long. 



It is remarkable for the numerous dark glands which are 

 mingled with soft hairs all over its surface, and which 

 resemble the kind of nails which upholsterers call tacks. 



A native of California, whence seeds were sent to the 

 Horticultural Society by Mr. Douglas. It flowers in June 

 and July. 



Fig. 1. is a magnified calyx from which the petals have 

 been removed ; the glands are seen scattered over its surface, 

 and from between the stamens projects the small hairy capi- 

 tate stigma. Fig. 2. represents the ovar)', opened to exhibit 

 the single ovule, and having the style smooth, but thickened 

 upwards, and a ring of hairs surrounding the stigma. Fig. 

 3. is a capitate gland very much magnified ; Fig. 4. is a 

 ripe pod surrounded by the calyx, and 5. is one of the ripe 

 olive-green seeds.
