the former hairy and fometiines longer than the reft. In the 

 preient fpecies we have often found the fifth ftamen perfect, in 

 which cafe the pubefcens of the filament generally difappears : 

 we have even feen fix perfect flamens in the fame flower ; fo 

 that a part fo liable to vary does not feem well fuited to eflablifh 

 a generic character upon. 



For the moft part the rudiment in this fpecies is hairy from 

 the top to below the middle ; but fometimes the pubefcence 

 barely extends fo far as to the middle. A more obvious 

 diftinction is afforded by the panicle being intermixed with 

 leaves, which in laevigata is nearly naked. 



Except the miferable reprefentation by Mori son, we do 

 not know that the broad-leaved variety Pentstemon pu- 

 befcens has ever been before figured ; there is a bad figure of 

 the narrow-leaved fort in Miller's Icones. 



Native of the Alleghana mountains in North-America. 

 Flowers in June and July, and ripens its feeds in the autumn; 

 at which feafon Miller directs the feed to be fown. It is a 

 hardy perennial or rather biennial, as, according to Miller, 

 the roots feldom abide more than two years.
