Sotipaco Purssi (S. Aumilis Pursh), 
The name humilis of Miller's Dict., n. 16, antedates that of 
Pursh and was given to a low form of S. Canadensis, included per- 
haps in the variety just described. 
ASTER NEMORALIS BLAKEI 0. var. 
Stems 1-2% ft. high; leaves not crowded, 214-3 inches long, 
A-H%, of an inch wide, lanceolate, coarsely toothed or entire, mar- 
gins not revolute; heads few or sometimes solitary; rays lilac- 
purple.

Intermediate between the’species and A. acuminafus. The 
type is confined chiefly to the bogs of the sea coast, whilst the 
variety extends inland, and is found even high up on the moun- 
tains. The specimens received from Mr. Rand are nearer to A. 
acuminatus than others that have been examined.

Botanical Notes. 
Peculiar “ Range” in an autecious Uromyces. It goes without 
Saying that parasitic fungi prefer certain portions of plants. 
Some confine themselves to the stem, others to the root, while 
a large number are limited in their growth to the foliage. 
The smuts, while wide feeders, usually produce their spores in the 
malformed ovary, and the ergots in a similar manner flourish in 
the inflorescence. 
Attention is here called to the position occupied by the fruit- 
Ing of two forms of a species of a rust, namely: Uromyces Caladii, 
which is very common upon Peltandra Virginica, and Arisema 
‘riphyllum. In the former host the zxcidia are confined almost 
€xclusively to the petiole and midrib of the leaf with occasional 
Cups along some of the secondary veins. The teleutospores, ap- 
Pearing later in the season, seem to prefer the blade of the leaf, 
but may be met with upon the petiole and midrib. In this case 
the greater limitation is on the side of the earlier stage of the 
Parasite, namely, the cidial form. 7
