6 P. Rapr'cans; an annual, creeping, glabrous herb; leaves 
sessile, lanceolate, remotely serrulated; pedicels axillary, soli- 
tary, twice the length of the leaves. YY. F. Native of China, 
from which place it was accidentally introduced to the botanic 
garden, Calcutta. Lobélia radicans, Willd. spec. 1. p. 948. 
The plant spreads over the soil and roots at every branch. The 
flowers are large for the size of the plant, of a pink colour. 
Segments of the corolla equal, unilateral, and narrow-lanceolate, 
with 2 green glands under the middle sinuses, opposite to the 
long, green, 2-lobed stigma. 
Rooting Pratia. Pl. creeping. 
7 P. Tuunze’rcu; glabrous; leaves sessile, decurrent, lan- 
ceolate, undulated, serrated ; pedicels axillary, solitary, longer 
than the leaves ; stems decumbent, rooting, filiform. XY. G.

Cult. A mixture of loam, peat, and sand is a good soil for 
the species of Pratia ; and they will easily be increased by divid- 
ing at the root, or by seed.

t. 29. Corollas large, of a reddish scarlet colour, and are as well 
as the peduncles and calyxes downy. This is a very poisonous 
species, even the smell of the flowers will cause vomiting, ac- 
cordingly Feuillee, and the milk of it, if by any accident it touches 
the eyes, occasions blindness.

Many-leaved Tupa. Fl. Aug. Sept. Clt. 1832. Pl. 5 to 
6 ft. pares 
Cult. The species of Tupa are deserving of cultivation 5 
every collection, on account of the beauty and singularity © 
their flowers. They are generally raised from seed importe 
from the places of their natural growth ; and when the plants 
are of a sufficient size, they are planted out into the open 
border in front of a south wall, where they flower in great 
perfection. In winter they may either be protected with the 
haulm of herbs, or be taken up and potted, and placed 
green-house or frame till the spring, when they should agai 0° 
planted out.
