198. Scitua (Kamassa, sed perigonium regulare) ancusTA 
(n. sp.) : gracilis ; foliis linearibus apice longe attenuato-seta- 
ceis flaccidis scapo brevioribus ; bracteis e basi lanceolata 
membranacea subulatis pedicellos erecto-patentes subzequanti- 
bus ; alabastris oblongo-linearibus ; foliolis perigonii linearibus 
obtusis stamina duplo superantibus. — Open woods and prai- 
ries, in south-western Missouri and Arkansas, as well as Texas: 
flowering from April to May in Texas, but from May to the 
middle of June in Missouri and Arkansas, when JS. esculenta, 
growing in the same region, has matured its seeds. The 
present plant is more slender than JS. esculenta, with narrower 
leaves, sepals, etc. ; but perhaps it is only a variety. — We are 
slow to believe that the Oregon species belongs to a different 
genus from the eastern.
