At Kew in Herb. Hooker there are four specimens of Jame- 
son’s from the Andes of Quito, labelled Didymodon luteum, evi- 
dently the types of Hook. Lond. Journ. 5: 48. No. 174 is anno- 
tated by Wilson: “var. foliis magis recurvis patenti-recurvo ser- 
rulato.” A part of 143 has the leaves much recurved as in 193), 
both of which are sterile. On the same sheet is a specimen of G. 
Mandon’s Plantae Andium Boliviensium Exsicc., no 1616, from © 
vicinius Sorata labelled Didymodon luteus Taylor, which quite 
agrees with Rusby’s specimens in its bright yellow recurved 
leaves, longer pedicels two or three in the same perichetium, and 
capsules twice longer than Jameson’s specimen’s. 
LEPTODONTIUM GRACILE C, Miiller, n. sp. Mapiri, 5000 ft (3111); 
Unduavi, 8000 ft. (3109). 
Plants bright yellowish green, stems slender, leaves squarrose 
and curled when dry; cells densely papillose and obscure above, 
clearer and oblong below, margins entire and recurved to above 
the middle, sharply and doubly serrate above. Plants all sterile. 
Allied to Didymodon cirrifolius Hpe. by its papillose leaves but 
with the aspect of ZL. gracilescens Mill. “Affine L. /uteo foliis 
longioribus quam ZL. gracilescenta acutioribus margine non repetito 
denticulatis.” ‘ E. Bescherelle, teste. 
LEPropontium GRimmiopes C. Miiller, n. sp. Sorata, 13000 ft. — 
(3192). 
Plants dark and discolored below, tips of the branches bright 
yellowish green, stems 3—4 cm. long, leaves squarrose, spreading 
and curled when dry, remaining undulate when moist, margins 
entire and recurved below with a few protruding teeth above, vein 
generally excurrent into a cuspidate apex, cells clear but papillose — 
at base, densely and finely papillose above. Plants sterile. =
