o(> ENGLISH BOTANY. 



not articulated. Stems setaceous, with several long bracts resembling 

 tlie loaves at the base of the panicle, but usually shorter than the 

 longest branches, though sometimes equalling or even exceeding 

 them. In var. a the flowers are solitary along the lower branches of 

 the panicle, which are 1 to 6 inches long : this racemose appearance 

 is produced by there being commonly only one branch of the cyme 

 developed. Occasionally both branches are developed, and then the 

 flowers are situated in the forks of the branches and at their ex- 

 tremity. Perianth leaves in var. a about ^ inch long, green with a 

 whitish midrib. 



Yar. 3 has a very different habit ; the stems being commonly much 

 shorter than the branches of the panicle, Avhich are stiffer and much 

 more spreading. The perianth segments are rarely above ,\ inch long 

 and more olive. The capsule is much darker brown. This form is 

 connected with var. a by a complete series of intermediate forms. 



Var. 7 scarcely deserves to be ranked as a variety, the relative 

 length of the capsule and perianth segments being variable both in 

 var. a and var. fi.

Pci'onnial. Stems rather slender, hollov^ or solid, not articulated, 

 leafy throughout or with the leaves all radical. Leaves narrowly 

 linear, channelled, not appearing jointed when dry. Flowers solitary 

 or in lax cymose fascicles arranged in an umbellato-corymbose panicle 

 with cymose bi'anches.

Not cajspitose, or subcaispitose. Rootstock extensively creeping. 

 Stems slender, more or less comj^ressed, hollow, with 1 or 2 leaves ; 

 basal sheaths pale, 1 or 2 of them with a lamina similar to that of the 

 stem leaves. Leaves all very narrowly linear, channelled above, not 

 appearing jointed when dry. Flowers solitary or in lax fascicles of 

 2 to 4, arranged in an umbellato-corymbose panicle, with the lower 

 branches once or twice branched, erect, longer or shorter than the 

 lowest bract ; ultimate branches very short, sjjreading-erect, or slightly 

 recurved. Perianth leaves nearly equal, oblong, obtuse, with pale 

 brown scarious margins; equalling the capsule or shorter than it. 

 Stamens 6, shorter than the anthers. Style about as long as or 

 shorter than the ovary. Capsule oval-subglobose, obtuse or shortly
