rieties with a chamois-coloured wool, by the names of ¬ Mai-tese cotton », « red cotton », « wood-coloured cotton ». These varieties harmonised in their principal character of the seeds being wrappcd in a green down, to which they adhere with tenacity, and thus, also, the chamois-coloured variety is found to differ from the Gossypium religiosum, to which, ou account of the colour of the wool, the Abbe Giovine had referred it, from which species it likewise de-parts in other positive charaeters, being neither arboresceut, nor with leaves palmate like the above. By the same charaeters, the Siamese white cotton is fojiud to differ from the common white cotton, or Gossypium herbaceum, to which there may be added the triangular lobes, with sharp points, the greenish-brown colour of the leaves theraselves, and the want of the purplish spots at the unguis of the corolla; lastly, the dimensions three times larger of ali the parts of the plant, and especially of the fruita.
Descrivimi. The Siamese cottoli has the root about the length of a foot, and of a brownish colour. The stem erect, cylindrical, of the height of two or three feet, round, co-vered with hairs, partly arranged in a stellary form, and adpressed; others erect and longer, so that it may be termetl hairy and rough at the same time. It is stained reddish brown, spotted everywhere, and divided into many alternate brauches, spreading and pyramidal. The leaves are of a brownish green colour, cut into three or five deep triangular lobes, which narrow to a point, and have an acute apex. The two external lobes are produced beyond the point of attachment of the petiole, and forra a deeply cordate base to the leaf, which is everywhere waving, almost suiooth above, and hairy below, with minute black spots, especially above the nerves, of which the centre one has a gland at the third of its length. The petioles are hairy. The flowers spring from the axils of the leaves either singly or in pairs, supported on peduncles, which are at first short, but ulti-mately longer than the petioles. They are also reddish and hairy. The corolla are large and very beautiful, twice or three times longer than the external calyx, and these last
