Gentiana Farreri, Balf. f.^ 



Perennial herb with thick roots and very many branch- 

 ing stolons freely rooting and spreading from a primary 

 central rosette, the stolons forming many new rosettes 

 from the leaf-axils at the rooting nodes. Stolons as much 

 as 18 cm. long prostrate at the base, then ascending, having 

 terete internodes about 1 cm. long and 2 mm. in diameter, 

 generally green and without surface papillae, sometimes 

 reddening. Leaves epetiolate thick opposite, each pair 

 connate and forming a vaginal somewhat loose sheath as 

 much as 5 mm. long ; lamina of upper region of stolon over 

 2 cm. long 2 mm. broad, in the primary rosette as much 

 as 6 cm. long 5 mm. broad (on rosettes of the stolons 

 somewhat smaller), linear not contracted at the base, 

 towards top narrowed into an acute or acuminate apex, 

 margin obscurely scaberulous, on both sides whitely- 

 papillose, concave above dark -green glossy, paler beneath,

 tube somewhat funnel-shaped not split, as much as 2 cm.
