Grass of Parnassus. 



Calyx of 5 equal herbaceous sepals, united at the base, 

 and by means of a thickish torus adherent barely to the very 

 base of the sessile ovary, quincuncially imbricated in aesti- 

 vation, persistent, reflexed in fruit. Petals 5, inserted on 

 the torus alternate with the sepals and just within them, 

 quincuncially imbricated in aestivation, ovate or obovate, 

 veiny, widely spreading, tardily deciduous. Staminodia (or 

 sterile stamens of authors) 5, opposite the petals, of which 

 they are probably a deduplication, inserted with them in a 

 series exterior to the true stamens, composed either of a 3 - 

 5-lobed and glandless dilated-cuneiform scale, or parted into 

 3 to 13 glandular-tipped setae which resemble abortive sta- 

 mens, persistent, marcescent. Stamens 5, alternate with the 

 petals, inserted just within them : filaments subulate, mar- 

 cescent : anthers cordate-ovate or oblong, introrse (not ex- 

 trorse as usually described), fixed above the base to the 

 point of the filament, two-celled; the cells opening longitu- 

 dinally by an introrse line. Pollen simple. Ovary closely
