Marshy places in almost every part of England produce this pretty plant in tolerable abundance. I t flowers in
June and in August or September the capsules are ripened, when they hang suspended by their upper part to the
common receptacle, while the lower and accuminated part has sprung away, so as to give the appearance o f arrowheads
; whence our English name, and whence also the Latin generic one, from rp iS three and yXu%iv the point
I have already adopted in this Flora the natural orders of Fluviales and Alismacea, which, together with the
Juncao-inea (containing, besides Triglochin, Scheuchzeria) and the Butomea, form, according to Richard, a small
group&of Monocotyledonea, distinguished from the rest by having seeds destitute of albumen and a superior
germen.
