ADOXA moschatelina L. said by Torrey 
and Hooker, to grow in boreal America and the 
Oregon mts. undescribed. My specimens 
from Europe. Genus near to Panax and Ar- 
alia. 
ADVENTINA Raf. Radiate. Perianthe 
globular 5 phyle, Sepals connivent equal ovate 
acute. Phoranthe flat chaffy. Rays 5 fertile, 
equal small and opposed to sepals, ligules short 
trilobe white, ovary and seed shut between the 
sepals and internal palea or chaff, similar to se-

bifid, pappus paleaceous multifid. Floscules of 
the disk minute yellow complete, chaff lanceo- 
late flat, corolla tubular 5toothed, stamens and 
style inclosed, pappus campanulate multifid. — 
Seeds black oblong compressed bivalved in rays, 
oblong terete in disk. Leaves opposite , flowers 
terminal. 
1. parviflora Raf. Stem slender branched 
diffuse smooth, leaves petiolate ovate acute an- 
gular dentate, lower rounder, upper nearly ses-

spontaneous for several years in the orchard 
of Bartram’s Garden, come with seeds from 
the South. Annual, Estival, pedal. Leaves 
thin smooth, flowers very small, white rays har-

genus, nearest Achillea , but habit calix and seed 
unlike. Named after its adventitious produc- 
tion near Philadelphia. Probably a Florida 
plant. Seen alive.
