there that we ascertained our plant to be of the species we 
have placed it in. The synonyms we have added which are 
not in the “ Nova Genera et Species Plantarum,” were oblig- 
ingly communicated by M. Kunth, who intends to intro- 
eice: them in a Synopsis or Appendix that is to conclude his 
work. 
The species was originally taken up from a very dilapi- 
dated sample, and its description has consequently failed 
in the requisite exactness. Canescens would have been 
selected for the specific denomination, had the plant been 
known to M. Kunth in the fresh state, no grayness being 
then perceptible. . The nascent leaves are indeed slightly 
hoary. . 
Introduced by Mr. Anderson from the Berlin garden. 
Flowered in September last in the Physic Garden at Chelsea; 
where the drawing was taken. Apparently quite hardy. 
Perennial and not annual, as presumed by M. Kunth. 
Observed by Messrs. Humboldt and Bonpland near 
Loxa, in Quito, growing at the height of 1050 fathoms 
above the level of the sea, in a temperate region. There 
is also a sample in the Lambertian Herbarium, collected by 
Messrs. Ruiz and Pavon in their Peruvian expedition. 
He.iopsis was established by M. Persoon from H. lawis 
of North America, the only other recorded species that we 
are aware of. The character has however been recast by 
M. Kunth as follows: ‘“ Calyx many-leaved, imbricate. 
Receptacle conical, paleaceous (chaffy). Florets of’ the disk; 
tubular, bearing both stamens and pistil; of the ray ligu- 
late, bearing only the pistil. Seeds without pappus. The 
species are herbaceous plants with opposite leaves, and ter- 
minal solitary peduncled deep yellow corolle.” Don MSS.
