126 15. R. GRABOWSKII. 



My original R. Grahowshii agi-ees very nearly with the 

 elaborate and excellent description given in the Flora Silesice, 

 and I therefore quote that work with much confidence. 

 There are slight diflferences between it and the English 

 plant of which the following are the chief. The stem is 

 called glabrous, and such is often its condition with us when 

 become old. Our j^lant has long hairs upon the under side 

 of the veins of its leaves, that of Silesia is said to want them. 

 The panicle is described as "ampla, ... pyramidata, apice 

 acuta, usque fere ad apicem foliosa,'* but it is not so in our 

 plant. Also the expression "glandulse null?e" occurs and is 

 probably intended to apply to the panicle : if so there is a 

 very marked difference between the plants; for with us the 

 peduncles and sepals bear an abundance of short (and there- 

 fore inconspicuous) setae or shortly stalked glands. 



There can be very little doubt concerning the true place 

 of this plant. Wimmer and Grabowski considered it as 

 much like and probably often called R. fruticosus (our R. 

 thyrsoideus), and its similarity to some states of that species 

 is considerable; but its habit is said to differ, and there are 

 many points of nonconformity. Wimmer makes it a variety 

 of R. thyrsoideus in his Fl. v. Schles. Pries, imd Oster. Until 

 we know more about it we shall probably act most wisely if 

 we retain it as a distinct species. Should it prove to differ 

 from the true R. Grahowskii (a name which seems to be now 

 unnoticed by German botanists) it might well be called 

 R. Borreri; the plant so named by Dr Bell Salter being 

 well known to be only R. Sprengelii.
