ZIGADENUS BRACTEATUS, Roem. & Schult. Syst. vii. (1830) 1559. 
Helonias bracteata, Sims, Bot. Mag. (1815) t. 1703; Lodd. Bot. Cab. (1828) t. 1380. 
This has usually been referred to Z. glaberrimus, but it appears to be 
a different species, though I have seen no specimens. It is stated in Lodd. 
Bot. Cab. to be native of Carolina and Georgia, whence it was introduced 
into cultivation in 1802. The species differs from Z. glaberrimus in its very 
much larger and broader bracts and shorter pedicels. In Z. glaberrimus 
the bracts scarcely equal the pedicels in length, while in Z. bracteatus they 
exceed the flowers. The inflorescence is also perhaps more compact and the 
petals apparently broader. This species should be looked for in association 
with Z. glaberrimus, with which it has apparently been confused. The figure 
in the Bot. Mag. is evidently from a very young specimen in which the 
inflorescence has not yet elongated, but, nevertheless, the size and shape of 
the bracts seem to separate it from Z. glaberrimus.

Said to resemble A. elegans, but has smaller flowers, narrower not glaucous 
leaves, stem shorter, and pedicels shorter. It apparently differs from 
A. sibirica.
