coarse habit of growth when thus treated, they are far from ornamental. The plant when grown in pots, on the 
contrary, is of a delicate habit of growth, and its stems, which become long and slender instead of beinw thick 
and bushy, require support. When it can be thrown into flower, it is highly ornamental. When kept in a 
greenhouse, these plants rarely flower at all, as they require abundance of light and free air. The species is said 
to have been introduced in 1827 ; but if so, it was soon lost, and was not re-introduced till 1835. It is a native 
of Peru, where it was found growing among broken rocks. 
2.— TROP^OLUM BBACHYCERAS, Hook. THE SHORT-HORNED INDIAN CRESS. 
Specific Character. — Leaves peltate, deeply cut ; segments six or 
seven, oblong-obovate, entire, sessile. Petals cuneiform ; segments of 
the calyx obtuse ; spur very short.

Description, &c This is a very elegant plant with yellow flowers, and a very slender stem, which requires 
support. It is a native of Chili, and is found in great abundance in the neighbourhood of Valparaiso, where it 
is called Flor de Perdiz (Partridge flower). It was first introduced in 1828, but appears to have been lost, or 
" at least," as Dr. Lindley observes, " it was never brought into notice till " about 1835 or 1837, when tubers 
of it were sent to various persons from Valparaiso. The culture it requires is exactly the same as that of 
T. tricolor um, which will be given in detail.

Engravings.— Swt. Brit. Flow. Gard. t. 270 ; Bot. Mag. t. 3169 ; 
Bot. Reg. t. 1935 ; Paxt. Mag. of Bot. vol.ii. p. 123 ; and am fig. 4

Specific Character. — Root tuberous ; stem slender, climbing, 
branched ; leaves peltately divided ; segments six or seven, obovate, 
entire, cuspidate. Petioles cirrhose. Petals unguiculate, a little 
longer than the rather closed permanent calyx, obtuse, quite entire.

Description, &c. — This very beautiful species has three distinct colours in the flowers 
resemble those of T. hrachyceras, and the stems are nearly equally slender. It is a very elegant climber ; and 
when it is ten or eleven feet high, and trained round a frame, it produces a very beautiful efiect. It is generally 
planted in pots and kept in a greenhouse, but it will grow vigorously, and produce a great abundance of flowers, 
in the open air. The tubers are flat and roundish, like those of the Cyclamen, and they should be laid on the 
surface of the soil, instead of being planted in it. If, however, the tuber be exposed to the violent action of the 
light, the plants will neither be healthy nor flower abundantly the first year ; though the bulbs from becoming 
stronger will produce more and better flowers the following season. When kept in pots, they do not require 
much room ; but, as the plants have very slender fibrous roots, which are easily withered by drought, it is a 
good plan to put the pot containing the Tropaeolum into anotlier pot a good deal larger, filling up the interstices 
between the two with sand or moss, which should be kept constantly wet. This imparts coolness and moisture 
to the pot within, without running any risk of rotting or injuring the roots, by keeping them in water. When 
grown in the open ground, the tuber should be planted in a sandy soil, and the stems should be trained over a 
trellis, as they are too slender to look well nailed against a wall. This species is a native of Chili, and it was 
introduced so long back as 1828 ; but for some time after its introduction, it was such a weak feeble plant as to 
appear scarcely wortli growing. The tubers being buried in the earth became sodden with wet, and consequently 
soft and rotten ; and thus, many plants died off without any sufficient cause being discernible, while those that 
remained alive became yellow and faded. It may be increased by seeds or cuttings, or offsets like other tubers.
