40. — Ripe seeds 0.35-0.40 line long, length equal to 2 or 24 
the upper one wanting; surface palish and shining, with a 
thick rather loose epidermis, the cells of which correspond 
with the reticulation of the seed.—A form from the mouth 
of the Columbia, Douglas, communicated by Dr. Hooker, has 
an obtuse capsule and thick ovoid seeds.— The differences 
between this and what I have named J. Tasmanicus, p. 453, 
s swamps near 
cino, California, a form which may be distinguished as var 
paniculatus ; analogous to the paniculate forms of J. pheo- 
cephalus and others; the heads of the simple or somewhat 
compound panicle are about 5-flowered; Hb. n. 41, not yet 
in bloom in May; no stipular appendages at the base of the 
leaves. Maturer specimens would be desirable.
