Sprengel unites this, S. cordifolia, S. triangularis, and 
S. orientalis, under one species; upon what principle of 
combination, we confess we do not comprehend. 
Stems erect, roundish, branched, densely leafy, covered 
over with glandular hairs. Leaves ovate-rhomboid, scarcely 
cordate, pilose, tapered into the petiole, which is longer 
than themselves; the upper ones becoming narrower by 
degrees, and finally sessile. Flowers terminal, often in 
threes, with filiform, very glandular peduncles. Outer 
leaflets of the Involucrum 5, pale-green, linear-spatulate, 
radiating, 3 or 4 times as long as the inner, (which are 
purple), very glandular. Radiant florets 6-7, yellow, 
3-toothed, with a pilose tube, which is bent inwards. 
Florets of the disk. yellow, funnel-shaped, with a campanu- 
late limb. Ovaria without pappus. Receptacle flat, palea- 
ceous ; the paleæ obtusely cymbiform, glandular at the end. 
EXPLANATION OF THE DISSECTIONS. 
1. A tip of one of the leaflets of the outer involucrum, shewing the 
nature of the glandular hairs by which it is covered. 2. A floret of the ray; 
with its accompanying leaflet of the inner involucrum. 3. A floret of the 
disk, with its palea. 4. The upper and lower ends of the style. 5. An 
anther separated to shew its figure and its appendage at the top. 6. The 
outside of the stigma seen before the lobes separate, shewing the hairy 
external surface.
