Gen. Char. Involucrum ( common calyx J (see fig. 5.) of many 

 (from 20 to 50) spear-awl-shaped, equal, upright scales, in a double 

 row, longer than the disk. Corolla compound, radiant ; florets of 

 the disk (figs. 1 & 2.) numerous, perfect, tubular, with 5 equal, 

 rather spreading segments ; those of the ray (fig. 3.) as many as 

 the scales of the involucrum, or more, strap-shaped, spreading, 

 with from 3 to 5 terminal, equal teeth. Filaments 5, in the florets 

 of the disk only ; hair-like, very short. Anthers united into a 

 cylindrical tube, with 5 notches. Germen in all the florets fertile, 

 inversely egg-shaped. Style (see figs. 1 & 2.) thread-shaped, some- 

 what prominent. Stigmas small, spreading. Seed-vessel none, 

 except the slightly converging calyx. Seed inversely egg-shaped, 

 a little compressed, furrowed. Pappus (fig. 4.) sessile, simple, 

 hair-like, rough, on the seeds of the disk only, which are hairy ; 

 wanting on the seeds of the ray, which are smooth. Receptacle 

 (fig. 5.) naked, pitted. 



Distinguished from other genera, in the same class and order, by 

 the involucrum or calyx of a double row of equal scales, which are 

 longer than the disk; the naked receptacle; and simple pappus on 

 the seeds of the disk only, those of the ray being destitute of pappus. 



Two species British ? 



DORO'NICUM PARDALIA'NCHES^T. Great Leopard’s-bane. 

 Heart-leaved Leopard’s-bane. 



Spec. Char. Leaves heart-shaped, toothed; the lowermost on 

 long, naked leafstalks ; the intermediate ones with the leafstalks 

 dilated into 2 broad semiamplexicaul (half stem-clasping) ears at 

 the base ; the uppermost sessile and amplexicaul. Hooker.
