_H. argophyllus_ (white-leaved, not argyrophyllus, silver-leaved, as
written in some catalogues).--An annual with woolly leaves, neater and
less coarse than H. annuus, with which it is said soon to degenerate in
gardens if grown together with it.
_H. annuus._--The well known sunflower in endless varieties, one of the
most elegant having pale lemon-colored flowers; these, too, liable to pass
into the common type if grown in the same garden.

_H. debilis var. cucumerifolius._--I have never seen the typical species,
but the variety was introduced a few years ago by Mr. W. Thompson, of
Ipswich, from whose seed I have grown it. It becomes 4 feet or 5 feet
high, with irregularly toothed deltoid leaves and spotted stalks, making a
widely branched bush and bearing well-shaped golden flowers more than 3
inches across, with black disks. It crosses with any perennial sunflower
that grows near it, simulating their flowers in an annual form. I had a
very fine cross with it and H. annuus, but the flowers of this produced no
good seed.
