wasp hanging from the under side of a dead limb or stick, though 
the color is different. Still more remarkable is the species 
on spruce trees (P. volvatus Pk.) in New York, and afterwards on 
Pinus contortus in California by Dr. Harkness. In this species 
the projecting margin of the pileus is incurved so as almost to 
enclose the pores, leaving only a small opening, 14-1% of ani 
across. Very similar to this, but probably specifically distinct, is 
a Polyporus collected in Oregon . C. Carpenter, a corre- 
spondent of Isaac C. Martindale, of Camden, N. J. In the speci- 
men seen the pores are entirely inclosed and occupy the upper 
surface of the cavity. The specimen appears to have grown on 
the upper surface of a fallen tree or perhaps on a horizontal 
branch. It is oblong in shape, about one and a-half inches long 
by one inch high and broad, and is of a yellowish color. It ap- 
pears to differ from P. volvatus in its rather larger pores with 
acute white mouths. The area occupied by the pores also is not 
so definitely limited, the length of the pores gradually decreasing 
from the center till the marginal ones are mere points without 
any appreciable depth. This has been named provisionally Poly- 
porus inflatus Ell. & Martindale, but additional specimens and 
information will be requisite to describe more fully all its charac- 
teristic features—/. B. Ellis, Newfield, N. J. 
STRUCTURE AND PHYSIOLOGY OF THE PASSION FLOWER (Passifor x 
lutea) —The passion flower of Ohio is greenish-yellow, about ad 
centimeters broad, having a crown tinged with purple. From pe 
center of the crown, surrounded at its base by the honey gland, 
rises the column of stamens, united into a sheath which above 
again separates into five filaments bearing the anthers. Inclu 
by this column of stamens is a stalk which bears the haley 
There are three styles. In case the flower does not set i 
falls off at a joint a short distance below the flower (Fig. 4).
