264 THE JOURNAL OF BOTANY 



that crudities in old drawings, especially when these have been 

 sketched from the living plants, which were afterward not avail- 

 able to the author at time of writing, frequently find their way 

 into the text. In other particulars, including especially the size 

 and typical shape of the leaves, both Lamarck's and L'ileritier's 

 descriptions and figures are sufficiently close to the widely distri- 

 buted plant commonly identified with them. The insistence of 

 both authors on the leaves being entire or subentire is important. 

 The leaves of S. ocymifolia are rarely toothed, and then have 

 broad not hardened teeth, while S. iolepis has little indurated 

 teeth or serrations. 



S. leucantha is readily distinguished by the entirely glabrous 

 achenes ; S. ocymifolia by the small number of involucral bracts 

 (4-8), and leaves which are on the average much larger. S. iolepis 

 differs from both in the violet colour of involucre and spots of the 

 disk (note the names " leucantha " and " albus " above), and the 

 indurated toothing of the leaves. It is also more pubescent, the 

 leaves producing characteristic, short, somewhat stiff, greyish or 

 whitish hairs.

The small, almost entire leaves and long peduncles, together 

 with the pappus, are the chief feature of the species.
