Cult. Mr. Sweet says the species of this genus thrive best in 
sandy gravel, and the pots must be well drained with potsherds, 
as nothing injures them more than too much wet; cuttings will 
root in the same kind of soil without glasses, in a shaded 
situation.

Calyx 5-parted, coloured, superior segment furnished with a 
free spur at the base ; lobes sometimes free, sometimes joined to- 
gether more or less. Petals 5, inserted in the calyx, and alternating 
with its lobes, unequal, irregular, 2 superior ones sessile and re- 
mote, fixed in the mouth of the spur, 3 lower ones unguiculate, 
smaller, sometimes abortive. Stamens 8; filaments free, closely 
girding the ovary, inserted in the disk; anthers terminal, ob- 
long, erect, 2-celled, bursting by a double chink. Carpels 3, 
closely joined into a trigonal ovary. Styles 3, connected toge- 
ther into one, which is 3-furrowed. Carpels 3, adnate to the 
base of the style or axis of the fruit, 1-celled, 1-seeded. Seed 
large, without albumen, filling the cell, and conforming to the 
cavity. Embryo large ; cotyledons 2, straight, thick, younger 
ones distinct, but at length closely connected together, and also 
adhering to the spermoderm, but rather distinct at the base ; 
radicle lying within the process of the cotyledons, bearing 4 
tubercles, which at length become radicles. Geert. fruct. 1.

axillary, 1-flowered. This order agrees with Geraniacee in 
the structure of the petals and calyx, but differs in the sta- 
mens being free, in not agreeing in number with the petals, as 
well as in the flowers being axillary, and in the structure of the 
fruit and seeds. It is curious that this is the only order in 
which the peculiar acrid flavour of @rucifer@ is found to exist. 
All the species are powerfully antiscorbutic. The flowers of all 
are handsome. 
Synopsis of the Genera. 
1 Trorz’otum. Calyx 5-parted, upper lobe furnished with 
a spur. Petals 5, 3 lower ones smallest or vanished. Stamens 
8, free. 
TROPHOLE. I. Tropxorvm. 
2 Macatita'na. Calyx 5-lobed, spurred, 2 of the lobes 
deeply parted, the other 3 connected into a 3-toothed lobe. 
Petals 5, unequal. Stamens 8, connected at the base. 
I. TROPA‘OLUM (from rporator, tropaion, which the Latins 
have changed to trope‘um, a trophy; the leaves are of the form 
of a buckler, and the flowers resemble an empty helmet). Lin.

Flowers larger than those of the foregoing species, yellow, 
darker on the inside at the base, and streaked with red and 
orange ; these are frequently eaten in salads, as well as the leaves ; 
they have a warm taste like the garden-cress, and hence the 
plant has its common name of Nastúrtium; they are likeme 
used for garnishing dishes. - The seeds when green are pick ed, 
and by some are preferred to most pickles for sauce, under ' e 
false name of capers. Elisabeth Christina, daughter of the ce e- 
brated Linnæus, we are informed by her father, observed the 
flowers of the great Indian-cress to emit spontaneously; at cer- 
tain intervals, sparks like electric ones, visible only in the eren 
ing. If this. be the case in this plant, itis probable the who 
possess the property more or less.
