MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[VOL. 11 



COLOMBIA: Cauca: Paramo de Las Papas, H. Bischler 894, 1042 p.p. (COL). 



VENEZUELA: Cumbre de San Hilaris, Goebel (as L. rujescens) (G) ; Bolivar: Chimanta 

 Massif, Rio Tirica above upper Falls, 2090 m, Steyermark & Wurdack 891 (NY); Rio Tinea 

 above Middle Falls. 1925 m, Steyermark & Wurdack 466 (NY); s.l., Cerro Venamo, 1400-1450 

 m, Steyermark & G. C. K. & E. Dunsterville 92630 p.p. (VEN). 



BRAZIL: s.l., Burchell (NY); near Rio de Janeiro, Glaziou 7468 (BR, G, NY); Rio 

 Negro, Manaos, Spruce, type of L. amazonica (MANCH-Kk960) ; S. Paulo: Jardim Botanico, 

 Fulford, Hatcher, Hell & Vital, 672 p.p., 698 p.p. (Hb Fulford). 



PERU: Andes, Mt. Campana, Spruce, Hep. Sprue, type of L. fusijera (isotype S, BR,

Other reports include Jamaica (Boswell, 1887), Puerto Rico (Hampe & Gottseho, 1852, 

 Pagan, 1939), Brazil (Angstrom, including /3 minor, 1876), Bolivia (Spruce, 1890), Chile- 

 Patagonia (Bescherelle & Massalongo, 1889, Massalongo, 1927, Montagne, 1850), and Tierra 

 del Fuego (Massalongo, 1885). These southern reports no doubt have reference to another 

 species since M. capillaris appears to be tropical and subtropical in its distribution. M. capillaris 

 is the most widespread of the species of Microlepidozia in Latin America.

Plants small, greenish-yellow becoming olive-brown, in depressed mats or 

 among other bryophytes; stems slender, prostrate, to 2 cm long, with leaves 

 to 0.35 mm broad, more or less regularly bipinnate; lateral branches numerous, 

 diverging at a wide angle, with many branches, leafy, often becoming flagelliform 

 in the outer part; ventral branches intercalary axillary, infrequent, with few- 

 celled scale leaves with rhizoids; stem in transverse section of a unistratose 

 cortical layer of 12 cells somewhat larger than those of the medulla. Line of 

 leaf insertion transverse. Stem leaves distant to subimbricate, deeply quadrifid 

 to within a cell of the base, the segments subulate, more or less curved, one, 

 or rarely two or three cells broad at the base, tipped with a row of two to four 

 cells; cells 12-16 p in diameter, the walls scarcely thickened, the cuticle coarsely 

 papillose. Stem underleaves distant, quadrifid to within a cell or two of the 

 base, with one or two of the segments shorter and less well developed, the cells 

 as in the leaf. Branch leaves and underleaves, smaller, with one less segment. 

 Plants dioicous. Female branches solitary, one to several on a stem, the bracts 

 and bracteoles similar, ovate the innermost series long ovate, bifid to one-fifth 

 their length, the margins short-dentate, -ciliate or -laciniate, the cells averaging 

 64 x 16 p., thin-walled, the cuticle striolate. Perianth long, contracted above, the 

 mouth ciliate-laciniate. Capsule stalk (seta) in transverse section with an 

 outer layer of eight large cells surrounding a medulla of many smaller cells. 

 Capsule long-ovoid, light brown, the wall of two layers of cells with char- 

 acteristic thickenings; spores brown, 12 p. in diameter, with coarse warts; elaters 

 to 300x10 p, bispial, the ends tapering, blunt. Male inflorescence not seen.
