this species, 7suga Canadensis was present and rather the more 
plentiful of the two, thus serving to show the great contrast 
between these two hemlocks. 
Cyperus souarrRosus L. 
This most beautiful little species of Cyperus has been found 
for the firsttime on the North American continent at Jacksonville, 
Florida, by Mr. A. H. Curtiss. The Florida Specimens agree 
exactly with Wright’s Cuba collection, No. 3355 (distributed as 
C. aristatus), also with plants from the Antilles, Surinam (Schwein- 
itz), and Bailies’ Niger Expedition of 1857-9 as well as with East 
Indian specimens.

~- * Juncus Georgianus Coville n. sp. 
: Perennial, densely tufted, 20 to 35 cm. high; stems erect, barely exceeding I mm. 
in diameter, striate when dry; leaves all radical; sheaths striate, stramineous, loose, 
minutely auriculate, commonly 2 to 4 cm, long, the innermost closely embracing the 
stem and sometimes reaching a length of 8 cm.; blades erect, some of them reaching 
at least the base of the inflorescence, transversely flattened, nodeless, striate on the 
back, I mm. or less in width, sometimes involute when dry, sharply acute at apex; 
inflorescence paniculate, about 5 to 10 cm. high, strict or only slightly spreading 5 
lowest involucral leaf foliose, not exceeding the panicle ; flowers rarely more than 25, 
usually not more than 10, inserted singly on the branches of the panicle, prophyllate; 
perianth 4 to 6 mm. long, its parts subulate-Janceolate, when young with a green mid- 
rib, usually reddish brown lateral stripes, and hyaline margins, when old stramineous ; 
stamens 6, one-half to two-thirds the length of the perianth, the anthers 1.5 to 2 mm. 
in Jength and several times longer than the filaments ; style and stigma long, the 
former often reaching 2, the latter 3, mm. in lengta; capsule about three-fourths a5 _ 
long as the perianth, narrowly oblong-lanceolate in outline, obtuse or broadly acute, 
mucronate, 3 celled ; seed about 0.4 to 0.5 mm. in length, oblong, reticulate, the areola 
linear and arranged transversely on the seed in about sixteen longitudinal rows. 
Type specimen in the U. S. National Herbarium, collected in May, 1869, 0D 
Stone Mountain, Georgia, by William M. Canby. 
a This plant is most nearly related to Funcus tenuis, but is easily distinguishable 
eo! from that species by its long radical leaves, its longer and brown-striped perianth, 
__ Rarrower capsules, and especially by its very long anthers. Contrasted with Ysscws 
_ tenuis, the long radical leaves, short stems, and large inflorescence of ¥. Georgianus 
give the plant a characteristic general appearance. Mr. Canby’s specimens were dis- 
_ tributed doubtfully identitied as ¥. semwis, and no botanist seems to have collected 
__ the plant since, until Mr, Small rediscovered it July 4, 1893, on the summit of Stone 
Mountain, at the altitude of 1686 feet. He collected it also on Little Stone Mountain, 
July 7, 1893, between 1,000 and 1,100 feet altitude. — : pans
