 Var. ELEGANS (Savi, Fl. Pis. ii. 161, as a species). This is said to be 

 distinguished by its solid stem, decumbent at the base, and smaller 

 head of flowers, which are longer pedicelled than thos-e of the true 

 T. hijbridum, which has a hollow and more ascending stem and larger 

 llower-heads. The variety is found by roadsides, &c., in many locali- 

 ties throughout the county. The true T. hybridum, figured in Sutton's 

 Perm, and Temp. Pastures, t. xxi (1891), is the commonly cultivated 

 plant which may be found as an escape by field borders and on rich 

 wafste ground in all the districts where it degenerates into the var. 

 elegans. Syme in E. B. says that the stipules are fewer nerved in true 

 T. hybridum, but I have usually found the hollow- stemmed plant to 

 have stipules with more numerous veins than the solid-stemmed 

 plant which is supposed to be T. elegans, Savi ; it may be that we have 

 only the wild form of 2'. hybridum and not the true T. elegans, which is 

 considered by many continental botanists as a distinct species. I must 

 confess to being able to see no specific distinction in the two Berkshire 

 forms mentioned, the differences in which appear to be owing to the 

 plants growing in a richer or in a poorer soil. This also appears to be 

 the opinion of M. Crepin ; see Notes sur quelques Plantes Raves ou Critique 

 de la Belgigue, fasc. ii. 20. 



T. hybridum is found in all the bordering counties.
