STOVE AND GREENHOUSE AQUATICS. 
leaves, and produces its white, scented flowers j 
from May to July ; a native of the Cape of 
Good Hope : this will even flourish out of 
doors. A. angustifolium, (narrow-leaved,) 
which has linear-lanceolate erect leaves, and a | 
two-forked spike of white flowers, blooming 
through the summer ; a native of the Cape. 
These plants belong to the natural order Jun- 
caginaceas ; they should be planted in lightish 
loamy soil and peat, either in tubs or largish 
pots, in about two feet depth of water. They 
are propagated by seeds or offsets. 
Byblis Unijiora (flax-flowered) is a very 
pretty greenhouse perennial, growing but a 
few inches high, with linear leaves beset with 
glandular hairs, and bearing blue flowers in 
May and June ; a native of New Holland, and 
belongs to the natural order Droseraceae. It 
does well in a light loamy soil, the pots 
half covered with water ; it is propagated 
by seeds. 
Cyperus. — This is a genus of sub-aquatic 
plants, of a reed or sedge-like habit ; it con- 
tains both stove and greenhouse species, natives 
of various countries. They form the type of 
the natural order Cyperaceaaj their culture is 
simple, requiring loamy soil and moderately 
large pots, set a little under water : they are 
propagated by division. 
JDamasonlum. — There are two species. D. 
indicum (Indian) is a herbaceous perennial of 
floating habit, with large broad heart-shaped 
leaves, growing erect out of the water, and hav- 
ing pretty white flowers of three broad petaloid 
segments, growing singly on stalks rising a 
foot out of the water; they appear from July 
to September; a native of the East Indies, 
and requires stove heat. D. ovalifollurn 
(oval-leaved) succeeds in a greenhouse ; it 
grows about the same height as the last, and 
produces white flowers in June and July; a 
native of New Holland. They belong to the 
natural order Hydrocharidaceae. They should 
be grown in largish pots in loamy soil, and 
set afoot under water; they are propagated 
by seeds, or by division of the plant. 
EUebocarpus oleraceus (Water Fern). — This 
is a very elegant, large-growing stove fern, 
with fronds of delicate texture, attaining when 
well grown two feet high and upwards : there 
are no flowers, but some of the fronds bear 
abundance of seeds (spores) ; these fruitful 
fronds appear to be cut into narrower segments 
than the others, by the rolling under of their 
edges. It is a native of the East Indies, at 
Tranquebar ; and belongs to the natural order 
Polypodiaceas. It should be grown in a large 
pot of loamy soil, and set in shallow water ; 
or, what answers the same end, the bottom 
hole of the pot may be closed up with a lump 
of clay, and the top of the soil kept below the 
rim of the pot, so that the surface may be 
kept just flooded. It is propagated by seeds, 
or viviparous shoots, or by division of the 
plant. 
El odea. — Two stove species. E. gnaianentds 
(Guianan) is a small annual plant with white 
flowers in July ; curious only. E. pulchella 
(pretty) is an East Indian species. They be- 
long to the natural order Hydrocharidaceas. 
A loamy soil suits them ; and they are pro- 
pagated by seeds. 
Eriocaulon (Pipewort). — Two species. E. 
fasciculatum (fascicled) is a curious dwarf 
annual stove plant, bearing white flowers at 
the end of summer ; a native of Guiana. E. 
australe (Australian) is a perennial plant 
growing a foot and a half high, flowering in 
June, and requiring a greenhouse. They are 
typical of the natural order Eriocaulaceae. They 
grow in peat and chopped sphagnum, the 
pots placed about half-way in the water. The 
annual one propagated by seeds, the perennial, 
by division of the plant. 
Euryale ferox (prickly) is a noble perennial 
stove plant, with roundish floating leaves, 
usually about one foot, but sometimes from 
two to three feet across ; the petioles, and the 
flower stalks and calyces covered with stiff 
prickles ; the flowers are red, produced from 
July to September. A native of the East 
Indies and China, and belongs to the natural 
order Nymphasaeeoe. It should be grown in 
loam, or rich muddy soil, and placed in at 
least two feet of water, in which it must 
always be kept. It is propagated by seeds, 
sown in the water. 
Herpestis. — Some of the species are pretty ; 
the two following are the most desirable : — 
II. JMonnieria (Monnier's) grows decumbent 
with wedge-shaped leaves, and bears small light 
blue flowers from July to September ; it is a 
native of India, China, the Moluccas, through- 
out North and South America, the West 
Indies, and Sandwich Islands. H. striata 
(upright) grows erect, and has cordate oval 
leaves, and pretty blue flowers in July and 
August ; it is a native of Brazil and some 
of the "West India Islands. They require a 
stove; and belong to the natural order Scro- 
phulariaceaa. They should be grown in small 
pots of rich soil, and set in shallow water. 
They are propagated by seeds, or by division 
of the plant. 
Heteranthera. — Two species. H. reni- 
formis (kidney-shaped leaved) is a floating 
perennial with kidney-shaped leaves, and blue 
flowers in August ; from South America. 
If. acuta (acute-leaved) has white flowers in 
June ; native of Virginia. The former re- 
quires a stove, the latter a greenhouse. They 
belong to the natural order Pontederaceai. 
They should be grown in pots of rich soil, and 
set in shallow water ; propagated by division.
