 various other places, but is not certainly native south of North Wales

Rootstock fle-shv, brancliin<;, the divisions somewhat resembling 

 tlie tubers of the .U'rusalem artichoke (l)ut smaller), pale brown, pro- 

 diieini; at the apex stems, but no tufts of radical leaves, as in S. 

 ofiiciiiale. The stems are 1 to 2 feet high, fle.xuous, much less winged 

 and less hairy than in S. officinale; the leaves taper towards the base 

 as well as the apex, and are more rugose, much less rough, and with 

 the hairs on the under side of the veins much fewer and shorter; 

 the calyx eegments are longer, narrower, and less bristly. Corolla 

 about ^ inch long, ochreous, but rather deeper in colour than in S. 

 oflicinale. The plant is of a paler and yellower green, and the 

 lower leaves have turned brown or withered before the flowers ex- 

 pand. The mature fruit I have not seen, but, according to M.Godron, 

 it is tubercular and contracted above the base.
