rarely free, 1-celled, sometimes partially or wholly abortive; ovules 
solitary, basilar, erect, anatropous ; style short or often wanting; 
stigmas as many as the ovaries, plumose. Fruit of 3-6 cylindra- 
ceous, oblong or obovoid carpels, which are distinct or connate, 
coriaceous, costate, when ripe separating from the base upward from 
a persistent central axis, the tips straight or recurved, dehiscing 
by a ventral suturé. Seeds erect, cylindraceous or ovoid-oblong, 
compressed or angular. Embryo conformed to the seeds. 
The carpels often appear indehiscent in the dried specimens, 
but they are all furnished with a distinct internal carinated suture 
which it may need moisture to open. The species have a rush- 
like appearance, and are generally found upon saline marshes near 
the seashore or inland, and often, also, in fresh water bogs and 
 marshes. The long, linear leaves are usually erect, sheathing each 
other and the scape at the base, often partially buried in the earth. 
Authors vary much as to the number of species, Kunth enu- 
merating 16, which Micheli reduces to 9. They are widespread, 
inhabiting the frigid and temperate zones of both hemispheres. 
Three species only occur in North America.

I. TRIGLOCHIN PALUSTRIS, L. Sp. РІ. 338 (1753). 
Perennial. Rhizome short, oblique, throwing out radical fibres 
and slender, fugacious stolons. Leaves narrowly linear, shorter 
than the scapes, 5-12 inches long, tapering to a sharp point; 
ligule very short. Scapes 1-2 from the same rootstock, very 
slender, striate, 8-20 inches high. Racemes 5-12 inches in length; 
pedicels capillary, in fruit erect-appressed and 214-3Y lines long. 
Perianth segments 6, greenish-yellow, ovate or roundish, in 2 
series, the inner a little higher. Anthers 6, sessile, in 2 series, 
each under a perianth segment, large, yellow: Ovaries of 3 
united carpels and as many celis and ovules; stigmas as many as 
the carpels, sessile, plumose. Fruit 3-374 lines long, slender, 
linear or clavate, tapering into a base scarcely thicker than the 
pedicel and tipped with 3 short recurved points. Ripe carpels
