472 - Best: REVISION OF THE 
7, LESKEA MIcROcCARPA W. P. Schimper, in Sulliv. Musci and Hepa- 
ticae of the U.S. 59. 1856. 
Plants smallest of the genus, in thin spreading tufts, yellowish 
green to dark green; stems 1-3 cm. long, creeping, radiculose, 
subpinnately branched; central strand minute or none: para- 
phyllia few, small, lanceolate: stem-leaves somewhat rigid, ap- 
pressed when dry, spreading when moist, 0.3-0.4 mm. wide, 
0.4-0.55 mm. long, ovate, subcordate, more or less narrowly 
long-acuminate, entire, basal margins revolute, costa subpercur- 
rent, rough below; branch-leaves erect-spreading, acute to nar- 
rowly acuminate, 0.2-0.25 mm. wide, 0.3-0.35 mm. long, some- 
times smaller ; leaf-cells small, angular, papillose on lower surface, 
usually smooth on upper ; median cells quadrate-hexagonal, irreg- 
ular, often indistinct, 5-7 # wide: alar oval-quadrate in about 6 
rows: monoicous: perichetial bracts somewhat loose, erect or 
spreading at tips, long and narrowly acuminate, costate ; pedicel 
smooth, erect, 5-7 mm. high; capsule erect, oval-oblong, reddish- 
brown, shining; urn about 1.5 mm. long and 0.6 mm. wide; 
exothecial cells large, irregular, rather thick-walled, roundish 
ovate-oblong, about 4 rows of smaller, oval, reddish cells about 
the mouth; teeth fragile, whitish, papillose, linear-lanceolate, 
0.25 mm. long, confluent at the somewhat broadened base, not 
markedly bulging when dry, dorsal line faint or none ; endosto- 
mial band thin, whitish, about 0.07 mm. broad; segments short, 
often rudimentary ; annulus narrow, one to two rows of cells; 
operculum conic, short-beaked ; spores slightly roughened, 9-13 
wide, mature in spring. On roots of trees, rotten wood, rarely 
on the ground. (PLaTE 15, Fics. 28-40.) 
TYPE LOCALITY : probably Alabama. 
Distripution: Florida (Langlois, Rapp); Alabama (Mohr, 
Earle & Baker); Louisiana (Langlois); Texas (Boll, Thomson, 
Wright). A specimen in the Gray Herbarium, Harvard Univer- 
sity, from Natchez, but without name of collector. 
ExsiccaTtaE: Drumm. Musc. Amer. (S. States) 89 as L. 
nervosa ; Sullivant, Musc. Allegh. 67 as L. polycarpa; Sullivant, 
Muse. Allegh. 69 as L. nervosa ; Ren. & Card. Musc. Amer. Sept. 
194 as L. gracilescens ; Langlois, Fl. Ludov. 246. 
as found in the Muhlenberg collection, It would therefore appear quite probable that 
the moss to which Hedwig gave this name is the same that M. Cardot has referred to 
L. polycarpa. But Renauld & Cardot in their Musci Americae Septentrionalis Exsic- 
cati 20. 194, for reasons best known to themselves, have applied this name to 4 me 
that belongs exclusively to the southern states, Z, microcarpa Sch., which in all prob- 
ability Hedwig never saw and which is quite different from his Z. yracilescens.
