6 P. RADI'CANS ; an annual, creeping, glabrous herb ; leaves 

 sessile, lanceolate, remotely serrulated ; pedicels axillary, soli- 

 tary, twice the length of the leaves. % . F. Native of China, 

 from which place it was accidentally introduced to the botanic 

 garden, Calcutta. Lobelia 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.

7 P. THUNBE'RGH ; glabrous ; leaves sessile, decurrent, lan- 

 ceolate, undulated, serrated ; pedicels axillary, solitary, longer 

 than the leaves ; stems decumbent, rooting, filiform. 1J. . G.

Cull. 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.

Cult. The species of Tupa are deserving of cultivation in 

 every collection, on account of the beauty and singularity of 

 their flowers. They are generally raised from seed imported 

 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 in a 

 green-house or frame till the spring, when they should again be 

 planted out.

 lar (f. 120. a.); tube entire, declinate, rather ventricose in

 segments ; the 2 lateral segments of the lower lip diverg- 

 ing, and the middle one more profound. Stamens and an- 

 thers combined, the latter bearded. Capsule ovate, 2-celled, 

 2-valved, dehiscing at the apex. Erect shrubs or subshrubs.

 tary, rarely crowded at the' tops of the stem or branches, so as
