The vast genus Chrysanthemum, including as it now 

 does Pyrethrum and a host of monotypic or oligotypic 

 genera, contains upwards of 1 20 nominal species, of which 

 Bentham considers that about 80 may be regarded as well 

 established. The dividing these into sub-genera and sections 

 is a great difficulty, founded as such divisions are chiefly on 

 the varying form of the pappus. The subject of the present 

 plate has been referred to Goleostephus, of which the type 

 is G. Myconis, L., and also to another genus Glossopappus, 

 which hardly differs. G. multicaule is a native of various 

 parts of Algeria ; it was first found in the Oran province 

 by Desfontaines, and has since been collected at Biskra 

 and elsewhere growing in sandy fields, &c. Judging from 

 a rather insufficient example, it extends to Marocco, whence 

 a specimen collected at Tangier by Broussonet is in the 

 Hookerian Herbarium at Kew. 



I am indebted to Mr. Lynch, of the Cambridge Botanical 

 Gardens, for the fine specimen figured here, which is much 



aprii 1st, 1887.
