present instance attained the length of near 60 feet within 
the space of three years from seed; and had not the swarm 
of runners it produces from both root and stem been re- 
peatedly stopped and removed, would probably have ex- 
tended itself on all sides to the same distance, and overrun 
the stove in which it grows. We can hardly conceive any 
single vegetable to form a more pleasing and durable orna- 
ment than this; which should be led round the hothouse 
along a lath or iron-rod, when the twining branches, 
clothed by a broad heart-shaped foliage, will constitute a 
thick evergreen wreath, from various parts of which, 
throughout its whole extent, a succession of large azure 
bloom is kept up for months together; so that the entire 
circumference of the house will be daily enlivened by fresh 
appearances of it. Individually the flowers are but of short 
duration; in the morning, of a vivid ultramarine blue; by 
mid-day, reddening at the plaits of the border ; before sun- 
set, wholly suffused with red, when they dissolve. The 
stem is.of a tough pliable wood, in external appearance’ 
much. like that of the Arrstorocuta Sipho. The foliage 
varies from cordate and undivided, to two three-lobed 
with broad lanceolate divisions. 
A stove plant, and should be placed in a border of 
rich loam formed within the tan-pit, and boarded off from: 
the tan down to the bottom. No plant can be easier to- 
multiply; the runners protruding their roots, even while 
suspended in the air, from beneath the leaf at every joint. 
Native of South America. Raised from seed brought 
from Vera Cruz about three years ago to Alexander J ohn- 
ston, gardener to Mrs. Hatch, Clayberry Hall, Essex; 
but whether gathered in the neighbourhood of the town, 
or in the interior of the country, cannot at present be ascer- 
tained. -
