a white fleshy narrow edge projecting internally from its base over the 

 disk ; teeth of the limb blunt and revolute in their edges ; teeth of the 

 throat erect, blunt, and having short crystalline cilia? on their edges. 

 Stamens included, about as long as the teeth ; filaments purplish ; an- 

 thers yellow, rather shorter than the free portion of the filaments, bifid 

 at both extremities. Pistil rather longer than the stamens ; stigma bi- 

 lobular, rounded ; style slightly tapered, glabrous, lilac ; germen light 

 yellowish-green, seated on a white disk. The unripe achenia are rough, 

 irregularly depressed over their surface, and each is raised on a sand-glass 

 shaped portion of the disk, the upper lobe of which projects from its 

 lower side a simple row of short dependent subulate hairs. 

 The seeds of this plant were received at the Royal Botanic Garden, from 

 Dr Fischer, under the name adopted, in 1830, and flowered for the first 

 time in May 1832- The profusion of lively coloured flowers in this spe- 

 cies, which is less deformed by coarseness of herbage than others, makes 

 it one of the most desirable for cultivation.

Descriptiok — Root tuberous. Stem filiform, greatly branched, branches 

 entangled, purple, shining. Leaves alternate, petioled, palma to-digitate, 

 round, (8 lines across) 6-lobed, soft, slightly villous, especially below 

 where paler, veined, lobes unequal, obovato-elliptical, generally only 

 one of them mucronate; petiole (1 inch long) filiform, resembling the 

 branches. Peduncles (above 2 inches long) solitary, opposite to the leaves, 

 pendent, capillary, slightly thickened upwards. Calyx of bright vermi- 

 lion colour, pentagonal, 5-cleft, the segments blunt, mucronulate, on the 

 outside tipped as well as the spur with purple, on the inside tipped with 

 green, whole inner surface glandular ; spiir erect, about one-third of the 

 length of the peduncle, awl-shaped, nectariferous. Petals 5 (3 lines long), 

 yellow, subexserted, inserted below the incisures of the calyx, obcordato- 

 spathulate, unguiculate, dilated at the base over a slightly villous pit. 

 Stamens 8, included ; filaments glabrous, colourless, dilated at the base, 

 and having on the outside of the insertion of each a pit similar to that 

 at the base of the petals ; anthers yellow, cernuous. Genrmi glabrous, 

 3-lobed, lobes keeled. Style glabrous, shorter than the stamens, grooved 

 on three sides, 3.toothed at the top, one of the teeth larger than the 

 others, and grooved. 



We received this plant from Mr Anderson of the Apothecaries' Garden, 

 Chelsea. It produced its truly splendid flowers in the greenhouse of 

 the Botanic Garden in March and April.
