and Jackson in the Index Kewensis i. 118 (1893), it was long ago 

 transferred to Vernonia by Lessing, Linnaea, iv. 268, a disposition 

 fully confirmed by a recent examination of the type preserved in the 

 herbarium of the Imperial Natural History Museum at Vienna. Un- 

 less some earlier specific name is found, the plant should certainly 

 stand as Vernonia. menthaefolia Less, 



EuPATORiuM MORiFOLiUM Mill. Gard. Diet. ed. 8, no. 10 (1768). 

 The type-specimen of this hitherto obscure species was recently exam- 

 ined at the herbarium of the British Museum of Natural History. It 

 was collected at Vera Cruz, Mexico, by Dr. Houston, and proves to be 

 identical with the plant long familiar under the later name of E. popii- 

 lifollum HBK. Nov. Gen. et Spec. iv. Ill (1820). E. morifoUum Mill, 

 seems to have been overlooked by Mr. Hemsley, as it is omitted from 

 the Biologia Centrali-Americana, but it is as well characterized as most 

 species of its date and must be reinstated for the well-known plant to 

 which the name was clearly applied. 



Eupatorium myosotifoUiim Jacq. Ic. PI. Rar. iii. 15, t. 582 (1786- 

 1793), & Coll. ii. 341 (1788). This species was described from culti- 

 vated specimens which had been raised from seeds supposed to come 

 from tropical America. The plant is well figured by Jacquin, and it is 

 clear, even from his illustration, that it does not belong to the genus 

 Eupatorium nor even to the Eupatorieae, for the style-branches are 

 short and decidedly recurved. An examination of an authentic speci- 

 men preserved in the herbarium of the Imperial Natural History 

 Museum at Vienna fully confirmed the correctness of the plate and 

 showed that the plant belongs to the baccharoid Astereae, probably 

 to the genus Conyza.
