1563. Flowers somewhat clustered into a spike-like raceme. 



Stems branchless ; leaves firm, mostly basal and glabrous, 

 elongated-linear, nearly or quite entire ; floral-leaves 

 bract-like ; flowers rather large ; corolla, except its mem- 

 branous expansions, outside densely beset with partly 

 stellular hairlets, its upper lobes unequally membranous- 

 expanded ; fruit ellipsoid ; seeds flat, without any mar- 

 ginal expansion. G. stelligera. 



Flowers on long scattered stalks ... ... ... 1564 



1564. Corolla, except its expanding membranes, beset with 



silk-like vestiture outside. 



Never tall, nearly glabrous ; stems slender, branchless ; 

 leaves greyish-green, from ovate- to narrow-lanceolar, 

 entire or seldom indented ; flowers somewhat fragrant, 

 axillary and terminal, solitary ; bracteoles absent ; lobes 

 of the calyx longer than the tube or as long ; corolla-lobes 

 all on both sides broadly expanded into pale-yellow 

 membranes ; transparent appendages of the upper corolla- 

 lobes for protection of the stigma- cover conspicuous ; 

 style invested with short soft hairlets ; fruit turgid ; 

 dissepiments considerably shorter than the fruit-cavity; 

 seeds pale-brownish, with a broad marginal expansion.

Corolla almost or quite glabrous outside ... ... 1565 



1565. Leaves entire or remotely denticulated. 



Slender, occasionally dwarf, somewhat beset with generally 

 appressed hairlets ; leaves from almost ovate- to narrow-

 mostly axillary ; bracteoles absent ; all the corolla-lobes 

 broadly expanded on both sides into bright-yellow mem- 

 branes ; style short ; cover of stigma invested with short 

 hairlets ; fruit small, its long stalk finally reversed ; seeds 

 plano-convex, dull-brownish, hardly margined. 



G. elongata. 

 Basal leaves mostly pinnatisected. 



Somewhat beset with appressed hairlets or rarely glabrous ; 

 leaves mostly radical, their lobes usually narrow ; stem- 

 leaves often only at the base of the flower-stalks, generally 

 diminutive ; flowers usually rather large, mostly or all 

 terminal, either solitary or two or few near together, on 

 separate stalks ; bracteoles absent ; upper lobes of the 

 corolla only unilaterally broad-expanded ; cover of stigma 

 beset with short soft hairlets ; dissepiment considerably
