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. 
Evparorium Mortrotium Mill. Gard. Dict. 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 . popu- 
lifolium HBK. Nov. Gen. et Spec. iv. 111 (1820). E. morifoliwm 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 myposotifolium Jacq. Ic. Pl. 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 1s 
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.
