CATALOGUE OF PLANTS.
157
PONTEDERIACEÆ. PICKEREL-WEED FAMILY.
PONTEDERIA, L. PICKEREL-WEED.
554 P. cordata, L.
Streams and muddy pond shores; common. Forms are some-
times found corresponding to var. angustifolia (Pursh), Torr.
XYRIDACEÆ. YELLOW-EYED GRASS FAMILY.
XYRIS, L. YELLOW-EYED GRASS.
555 X. flexuosa, Muhl., var. pusilla, Gray.
Peat bogs and sandy shores; rare and local. Hadlock Ponds
(Wm. H. Dunbar, Rand); — Breakneck Ponds (A. H. Smith,
R. H. Day); — Jordan Pond (T. G. White, Redfield, Annie M.
Rand). It is possible that this may be distinct from X. flexuosa,
and entitled to specific rank. See Bull. Torr. Bot. Club, xix. 38,
where this plant is described as Xyria montana, Ries, — Xyria
being an evident typographical error for Xyris. The specific
name montana, there chosen, is most unfortunately inappropriate.
JUNCACEÆ. RUSH FAMILY.
JUNCUS, L. RUSH.
556 J. effusus, L. COMMON RUSH.
Very common in wet ground.
557 J. filiformis, L.
Rare. Edge of pool on Heaths Brook, Tremont, near head
