The American species belong chiefly to the section Gentianella, which 

 has sepals imbricately connate below, without intracalycine membrane; 

 calyx-tube not unilaterally divided ; corolla with 1-2 nectaries for each 

 petal, often fringed at its throat, and with 5-7-9 veins for 

 each petal. 



i. GENTIANA MAGELLANICA Gaud. 



Stem rather strict, sparsely branching, angled. Cyme 

 lax, corymb-like. Leaves subcoriaceous, oblong-spatulate, 

 margin rough, upper leaves acutish, lower obtuse. Calyx 

 deeply 4-cleft, its lobes ovate, acute, nearly equaling the 

 corolla. Corolla-lobes 4, oblong, obtuse, erect. 



S. Patagon., by Rivers Gallegos and Sta. Cruz. ; Magel- 

 lan, annual in S. Fuegia and Falklands. 



2. G. PATAGONICA Griseb. 



Stem rather strict, branching, angled. Cymes lax, race- 

 miform. Leaves subcoriaceous, elliptic-oblong and spatu- 

 late-obtuse, margin smooth. Calyx 4-cleft, its lobes ovate, 

 acute, half as long as the corolla-lobes. Corolla blue? 

 slender, salverform ; its lobes ovate-oblong, subacute, 

 equalling the tube. (Fig. 85.) 



Magellan ; Fuegia, passim. ; in steppes by the moderate 

 rainy-forest region. S. Patagon., by Hatcher in low, wet 

 .ground near Rio Sta. Cruz, Jan. 9. The flowers of the 

 Hatcher forms are yellowish-purple, and 4- and 5-merous 

 in the same inflorescence. A more slender form, got by 

 Hatcher on the Cordilleras of S. Patagon., has the corolla 

 narrower, and the stems more sharply angled (see var. Genttana pata-

"G.pafagomca differs from the Tasmanian and New Zealand G. mon- 

 tana Forst, only by rather broader and more obtuse segments of the less 

 deeply divided calyx." (J. D. Hooker.)
