 Flowers very similar to those of Fpipaclis, differing in the longer and more 

 slender column, tho stigma wholly beakless, and the anther shortly stipitate so as 

 to be nearly or quite above the level of tho top of the stigma ; pollen-masses not 

 connected nor attached to a gland ; flowers erect, the perianth connivent or the 

 lower sepals somewhat spreading. — Caulescent and leafy, with small bracts (our 

 only species leafless and scarious-bracted) ; rootstocks cree])ing. 



A crcnus of about half a dozen species, peculiar to Europe and Northern Asia. The S. Ameri- 

 can frcnus Chhrav, to which the following species was fn-st referred, has the stems leafy at base

1. C. Oregana, Reichenb. f. Parasitic, whole plant white, a foot or two hi'-li 

 with 3 to 5 somewhat dilated sheaths and usually a few free linear-lanceolate bracts 

 above, an inch or two long ; floral bracts very small : flowers few to many, sessile or 

 nearly so: perianth about 6 lines long, gibbous at base; sepals and petals oblong- 

 lanceolate, nearly equal; lip a little shorter, the saccate base with broad win^-like 

 margins as in the last species, tho nerves somewhat tuberculate-crested within • 

 upper portion very broad and suborbicular, the nerves in tho centre wavy-crested : 

 column 2 lines long, about twice longer than the anther. —Liniwa, xli. 53. C/do-
