cells larger and brown, a few hyaline ones near the vein, others 
conspicuously porose, becoming long, spindle-shaped above and 
oblique along the margin. Monoecious antheridia in small buds 
on the tomentum in the axils of the leaves. Pedicels 15-20 mm. 
long, much twisted to the left; capsule 3-4 mm. long, erect, smooth, 
ovoid, largest at base, abruptly contracted or with a short neck; 
lid with a slender oblique beak 2 mm. long ; mouth small, teeth 
short, slender and bifid. 
Compared with and equal to Mandon Plantae Andium Bolivi- 
ensium, No. 1609. Hab. vicinius Sorata, also Songo, 1857. 
Nearest to D. speciosum Hk. & Wilson. Compared with No. 
325 of W. Jameson’s PI. Aequatoriales from which it differs in 
its more slender habit, shorter leaves and pedicels half as long. 
Dr. C. Muller, also recognized this as a new species. 
Dicranum species? Yungas, 6000 ft. (3115). 
These specimens are sterile, and have baffled Dr. Muller, and 
Mr. Mitten as well. They have been compared with all the speci¬ 
mens at Kew likely to be the same. Mr. Mitten sent me a por¬ 
tion of his specimen of Dicranum Mittenii CM., but they do not 
agree. Dr. Muller named them Campylopus concolor Hook., but 
they were compared at Kew with specimens in Hooker’s herba¬ 
rium collected by Lindig in Bogota, and they differ in being much 
stouter plants of a glossy yellow color, with longer and broader 
leaves, which are serrate only at the apex and have a much broader 
blade. 
Pilopogon gracilis Hook. Near Yungas, 6000 ft. (3159 in part). 
Compared with Hooker’s specimens at Kew collected by Wed¬ 
dell in the Province of Yungas, Bolivia, May, 1847, with which 
they agree in every way. The leaves are hyaline at the basal an¬ 
gles and these cells extend up along the margins; the short trans¬ 
verse walls of the cells are thickened; the vein is broad, the 
margins incurved, and there are a few teeth at the apex. The 
perichetial leaves end in a very long tip, often extending half the 
length of the pedicel. 
Dr. Muller gave this a manuscript name under Catagonio. 
Campylopus trivialis C. M. n. sp. Mapiri, 2500 ft. (3196). 
Plants loosely matted, dirty green; stems flexuous, not rigid, 
3-5 cm. long, usually simple, occasionally with crowded branches
