racters are amplified in later and fuller descriptions of the species 

 in order to emphasize differential characters in well-marked 

 varieties, Linnaeus' original description is here transcribed from 

 ' Hort. Upsaliensis,' p. 105 : 



"Badixvivax. Caulis erect us, firmus. Folia lato-lanceolata, 

 margine (cartilagineo serrato) scabro. Flores subaggregati pri- 

 moribus sessilibus. Foliola calycina ovata in acumen lineare 

 acuminatum longitudine tubi desinentia, subfusea, patentia : hinc 

 calyces squarrosi. Petala rubra, crenata, lateribus reflexa, circa 

 centrum obscurius rubra. Anthera) creruleaB. Folia inferne 

 caulem non vaginantia. 



The rootstock is much branched, and the barren shoots are 

 vigorous, numerous, and foliose, thus giving the plant a ca)spi- 

 tose habit. The stems are almost invariably smooth but not 

 shining, angular and unbranched, uuless it may be at the very base, 

 where two branches may spring almost together from the crown. 

 In D. Schlosseri and cruentus the stems are terete. The leaf- 

 sheath is very long, as in D. ambiguus. The bracts, unlike those 

 of D. barbatus, are broad and mucronate. The calvx is con- 

 stricted at the base of the teeth, and this character further 

 distinguishes it from D. slavonicus and Borbasii; the teeth are 

 9-nerved, and in this character differs from D. pelviformis. The 

 petals, as might be expected, vary much in tint, from dark 

 purple to rose-coloured and white, and the dentation is irregular. 

 They do not vary so much in length as in the proportion of 

 lamina to unguis. Linnaeus makes the curiously erroneous 

 statement that D. barbatus differs from this species in having 

 1-nerved instead of 3-nerved leaves ; whereas both species agree 

 in having 5-nerved leaves, though the two lateral nerves are 

 obscure.
