The first species has the root very large and much branched: it 

 is composed of many strong fibres, which are connected at the top, 

 like those of Asparagus. From this arise many stems, in number 

 proportioned to the size of the root, near two feel high, very slender 

 at the top, woody, round, hairy, and not branched. The leaves are 

 cordate-ova le, acuminate, smooth, hardish, quile entire, glaucous- 

 green, the midrib and sometimes the edge of the leaves a hllic 

 hiiiry: the petioles short. Peduncles axillary, many-flowered, re- 

 sembling proliferous umbels. The calyx small, green, divided at the 

 end into five brislles. 'i'he corolla is commonly white: the follicles 

 ovate-acuminate: the seeds small, l)rown, and wrapped in Avhilc 

 cotton. It flowers in June, sometimes in May, and continues flower- 

 ing to August, and is a native of most parts of the continent of 

 Europe.
