2. SCHEUCHZERIA, L. Sp. Bl. 338 (1753), 
Rush-like bog perennials with creeping rootstocks and erect, 
leafy stems. Leaves semiterete below and plane above, striate, fur- 
nished with a pore at the apex and a membranous, ligulate sheath 
at the base. Flowers small, racemose. Perianth 6-parted, regu- 
lar, biserial, persistent. Stamens 6, biserial, inserted at the base 
of the segments; filaments elongated; anthers linear, basifixed, 
extrorse. Ovaries 3, rarely 4-6, separate or connate at the base, 
I-celled, each cell containing one or two collateral ovules. Stig- 
mas sessile, papillose or slightly fimbriate. Carpels 3-6, shortly 
connate at base, divergent, inflated, coriaceous, 1-2 seeded. Fruit 
a follicle, thick, flattish-oval, dehiscing laterally, containing one 
or two smooth seeds which have a clearly marked raphe and 
a thick hard testa. Seeds exalbuminous, straight or slightly 
curved, loose in the carpel. 
Only one species is known. 
I. SCHEUCHZERIA PALUSTRIS, L. Sp. Pl. 338 (1753). 
Leaves 4-16 inches long, the cauline diminishing to bracts 
among the inflorescence. Stems one or more, rising from a long 
creeping rootstock, and usually clothed at the base with the re- 
mains of old leaves, 4-10 inches in height; sheaths on the radical 
leaves often 4 inches in length, with a ligule nearly 5 lines long. 
Pedicels 3-10 lines long, spreading in fruit. Flowers white, few, in 
a lax raceme; perianth segments acute or obtuse, membranaceous, 
I-nerved, 1% lines long, the inner ones narrower. Stamens 2%- 
3 lines long. Follicles 3-4 lines in length, divergent, only slightly, 
if at all united at the base. Seeds oval, fuscous, 2% or 3 lines in 
length, with a very hard testa. 
This plant occurs rather rarely in deep quaking bogs, among 
moss and grass, from New Brunswick to Hudson’s Bay in Canada, 
from New England to New Jersey, and westward to Washington 
and California. It is also an inhabitant of Northern Europe and 
Asia. (Plate XXIII. with a flower magnified.) 
3. LILAEA, Humb. et Bonpl. Pl. Жа. 1. 221 (1808). 
Annual stemless, paludose plants, with simple, slender scapes 
and radical leaves which are slightly dilated at the base. Flowers 
moncecious and dimorphous, the one sort solitary, fertile and dis-
