to appear acute, lowest short, ovate, acute or acutish ; pappus 
plumose, scanty, weak, scarce half the length of the corolla- tube ; 
achenes as long as corolla-tube and sparsely hairy. 
Collected on the top of Blowing Rock Mountain, Watauga 
County, N. C., by Mr. A. A. Heller, August 18th, 1890, and 
found mixed with L. graminifolia, Willd., in his Nos. 81 and 82. 
The specimens of the latter were from lower elevations and are 
remarkable in having involucral bracts wholly destitute of glan- 
dular dots. THos. C. PORTER.

Last September, while collecting along the shores of Park | 
Lake, six miles northeast of the college, my attention was at- 
tracted by an unknown Aleocharis growing in the shallow water. 
I had previously collected here, E/eocharis olivacea, E. quadran- 
gulata, FE. palustris var. vigens, Cyperus Engelmanni, and 
Scirpus Smithiz; and now to be able to add another, and that an 
unknown Lleocharis, to my already overflowing vasculum, was 
good fortune indeed. Specimens afterwards sent to Dr. Sereno 
Watson, proved that Eleocharis Robbinsii was no longer confined 
in “ shallow water, New England to Florida.” 
This species and £. olivacea are new to the flora of Mich- 
igan. On the shores of Pine Lake, two miles southeast of Park 
Lake, are found Fimbristylis autumnalis, Scirpus Torreyi, Hemt- 
carpha subsquarrosa. 
Carex umbellata was found in good fruit, May ue 1890, on 
bluffs along Grand River, ten miles west of the college. At the 
same time and place was collected Carex communts, var. 
Wheelert. \n former years, near Hubbardston, I had col- 
lected about a “Deer Lick” Eleocharis pygmea, E. rostel- 
lata, and Scirpus Olneyi, and on bluffs near by the rarest 
of all Michigan Cyperacee—Scirpus ClintonitZ. In the same 
vicinity are tound Carex Richardsoniz, C. Carevana, C. sychno- 
cephala, C. platyphylla, C. triceps, var. hirsuta, C. aquatilis, C. 
retrorsa, var. Hartit, C. squarrosa, and many other species. 
Carex tenuiflora,C. paucifiora and C. Magellanica, are found in 
a small sphagnous swamp near the college.
