Stem rather strict, sparsely branching, angled. Cyme 

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

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

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

 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. 

 gracilis below).

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