52 MISSOURI BOTANICAL GARDEN, 
Y. flaccida lineata Trelease. 
A garden sport, apparently of var. glaucescens, but in habit more resem- 
bling Y. jilamentosa media, having the young leaves striped with dingy or 
yellowish white, the variegation soon fading for the most part. 
Cultivated at the Missouri Botanical Garden and said to 
have come from Haage & Schmidt in 1881. Doubtless it 
is this by which the variegated form of Y. filamentosa 
proper is represented in many gardens.

The filiferous-leaved ‘* bear grasses ’’ of the southeastern 
Atlantic States are not easily disposed of in an attempt to 
monograph the genus to which they belong, partly because 
they are more commonly seen in cultivation than in a state 
of nature, partly because of their interblending characters,
