[ Elatine . 
Seeds cylindrical, furrowed and transversely striate. — Named 
from iXanvr], some plant found growing among corn and very 
dissimilar to our present one. 
1, E. hexandra. DC. ( [hexandrovs TP.) ; leaves opposite spa- 
thulate, flowers alternate pedicellate erect hexandrous tripe- 
talous, calvx-segments spreading, capsule turbinate concave at 
the summit 3-celIed, seeds 8 — 12 in each cell nearly straight 
ascending. E. tripetala Sm. E. FI. E. Hydropiper E. B. 
t. 955. (not L.) 
Margins of ponds and ditches, rare. Bomere pool, near Condover, 
Shropshire; Hedge-Court Pond, near East Grinstead, Surrey; 
Binfield, Berks ; Crawley and Maresfield, Sussex ; Coleshill pool, 
Warwickshire; also in Cornwall, Leicestershire, Cheshire, and Angle- 
sea. Loch Ruisky. near Callender, and Loch of Cluny, Perthshire ; 
Loch of Drum, Kincardineshire ; Loch Fadd, Isle of Bute. ©. 
7 — 9. — A minute, procumbent, much-branching plant, with axillary 
solitary flowers. Petals rose-coloured. Seeds mostly beautifully 
ribbed and transversely striate. 
2. E. Hydropiper L. ( small octandrous TP.) ; leaves opposite 
spathulate, flowers alternate sessile erect octandrous tetrape- 
talous, calyx shorter than the petals divided to the base, seg- 
ments ligulate, capsule roundish depressed 4-celled, seeds about 
4 in each cell pendulous uncinate. Linn. Flor. Suec. ; Borr. 
in E. B. S. t. 2670 (excl. a.). E. nodosa Am. 
Rare ; Farnham, Surrey. East end of Lyn Coron, Anglesea, 
growing with E. hexandra. Newry, and at the Lough Neagh outlet 
of the Lagan Canal, Ireland. ©. 8. — Asserted by Seubert to be the 
Hydropiper of Buxbaum, and consequently of Linnaeus, but certainly 
most distinct from E. Hydropiper DC., the E. major of Braun, 
which is that figured in Vaillant’s FI. Par. t. 2. f. 2., and Lam. 111. 
t. 320. f. 2. This last is much stouter, has the seeds almost straight 
and as numerous as in E. hexandra, capsule depressed, twice as large 
as in our two species and the calyx cleft only to about the middle of 
the segments which are short very broadly ovate and erect; the flowers 
are evidently pedicellate : it is allied to, and united, we think erro- 
neously, by Seubert, with E. hexandra. We have never seen speci- I 
mens except from the neighbourhood of Paris.

Sepals 5 or 4, persistent, distinct or united. Petals as many, 
rarely wanting. Stamens as many as, or double the number of, 
the petals, inserted upon a fleshy elevated disk, supporting the 
ovary, or a ring. Anthers opening longitudinally. Ovary 1. 
Styles 2 — 5. Capsule 1 -celled ( sometimes only so at the summit 
and 2— 5-ceiled below), 2 — 5 valved or opening at the summit 
with teeth, placenta central and free in the 1 -celled capsules, in
