stock remains but two seasons, one while it bears leaves and flowers, 
and another while it serves as a reservoir in which to lay up a supply 
of food. 
After the second year a constriction takes place between the effete 
biennial rootstock and the growth above it which at last results in 
their entire separation, leaving a scar at the point of attachment, e. 
The peculiar feature of this plant, however, is this: The lower 
axils of the leaves in early spring contain leaf-buds, at the base of 
which in each case we find but one root, so that in this case the roots 
preserve the phyllotaxy of the leaves, since they agree with the posi- 
tion of the buds which are ifi the axils of the leaves. The roots of 
these leaf-buds, d^ remain for one year attached to the parent plant 
and serve them as suppliers of sap. When, after the second year, 
this portion of the parent stem decays, the roots are separated from 
it, but carry with them the still quite undeveloped buds (Fig. 4), which 
are capable of forming a new plant. I know of no parallel case. 
The phyllotaxy is ^, or occasionally f. I consider the scape as the 
end of the rootstock, the two buds being axillary, the upper one the 
larger. This would make it a case of sympodial growth.

Notes from Southern New Jersey.— The following plants, col- 
lected in 1883, are not given in the Preliminary Catalogue of the 
State, and may therefore be worth noticing : 
Chionanthus Virginica^ L. — This is an addition to the flora of the 
State ; locality, near Buena Vista Station, N. J., and Atlantic City 
R. R. Rare, but probably occurs more frequently in a locality called 
"Thick Hole/' Cumberland Co. 
On July 4th I collected in Stephen's Creek, near Estellville, At- 
lantic Co., Potamogeion Oakesia/n^s, Robbins. I am not aware that 
this plant has been reported from New Jersey before. 
Perhaps the only definitely known locality in the State for 
Scleria reticularis^ Michx., is near Main Road Station, N.J. S. R. R-» 
seemingly not very abundant.

Note on >Ecidium Bellidis.— The Vadium upon the common 
daisy, which has hitherto been regarded as a spore-form of Pucania 
Composilarum,\^ a true heterocismal uredine. A series of expenmentai 
cultures which I have made during the past four months nas 
demonstrated the fact that JScidium Bellidis is one stage of ^'iT^'f'"' 
obscura, SchrBt., which occurs on Luzula. The P. Luctila i^i"- 
is a totally distinct species having smooth, elliptical uredosporcs. 
Those of P. obscura are round and rough.
