Dedicated to Mr. J, G. Baker, of the Royal Herbarium at Kew, 
in grateful acknowledgement of the many kind favors received 
from him while at work, under his charge, on Dr. Rusby’s Ferns 
and Mosses, and also as a small recognition of the task he accom¬ 
plished in mounting and putting in order the Herbarium of W. P. 
Schimper, presented to Kew by the Baroness Burdett-Coutts. 
This species was first named H. castanea, from the description 
only, and when submitted to Dr. Muller he discovered three new 
species in it; but as we can find but one specimen in our packet, 
and have no means of determining which of his names apply to 
our species, we have discarded all his manuscript names. 
Hookeria purpureophylla C.M., n. sp. Near Yungas, 6000 ft. 
1885 (3164). 
Plants small, light reddish brown, .7-1.5 cm. high; stems 
branched, distichous, or flattened; leaves small, 1 mm. long, 
closely imbricate, appressed with flexuous, filiform spreading 
points; veins ending below the rounded part of apex, toothed at 
the back of the leaf above; margins serrate to below the middle, 
more coarsely so above; cells papillose, upper wine-color, lower 
colorless and longer; pedicel purple, 15 mm. long, arched at 
apex; capsule 2 mm. long; neck tapering; lid conic-rostrate. 
Peristome not yet matured, torn off with lid. 
Compared with H. (Callicostella) rufescens Mitt. (Spruce, no. 
629) from which it differs in the longer acuminate leaves; they 
also are more slender and not so crisped as those of H. purpurea 
and are too acute for H incurva. Our plants are mixed with a 
small, golden yellow Hypnum in fruit, and a brown Hepatic, but 
we cannot find the two species of Hookeria , indicated by Dr. Muller 
in his letter by two other manuscript names. 
Hookena crispa C.M. Near Yungas, 4000-6000 ft. 1885 (nos. 
3161 and 3161a). 
Hookeria falcata Hook. Near Yungas, 4000-6000 ft. 1885 
(3162). 
Braunia canescens Sch. in G. Mandon, Plantae Andium Bolivien- 
sium, Exsicc., no. 1641. Vicinius Sorata, 1858, Mandon. 
Sorata, 10000 ft, February, 1886, H. H. R. (no. 3153). 
Plants crowded in brown masses, stems copiously branching, 
less than 2 cm. high, discolored beneath, green at tips of branches; 
leaves closely imbricated, lower ones with short white tips, those 
at the ends of the branches frequently prolonged into flex-
