Hab. on trees, Oakland, common, Bol. 
This diagnosis completes the short comparative description given of this species 
in the Trans. Amer. Phil. Soe., vol. 13, p. 6. It is very small, not larger than the 
small forms of O. strangulatum, Beauy., with which it has some affinity by the peris- 
tome and form of the leaves. 
110. O. Kingianum, Spec. nov. Monoicum, cxspitoso pulvinatum.  Caulis 
erectus, pollicaris parce dichotome ramosus, inferne brunneus, superne 
obscure viridis. Folia humida erecto-patentia, breviora, ovato-lanceolata 
acutiuscula nervo carinata, e basi usque sub apice revoluta, reticulatione 
inferiori quadrato-elongata vel rectangulari, superiore quadrata, obscure 
granulosa et minute papillosa. Folia perichzetialia conformia vix longiora. 
Capsula in pedicello 2-3 lineas longa, exserta, ovalis, brunnea levis, collo 
brevi in pedicello attenuata, ore constricta, peristomii 16 dentes pallidi, 
breves, obtusi vel erosi germinati ciliis 8 interpositis e duplo serie cellularum 
coinpositis brevioribus. Calyptra elongata capsulam ad basim usque inte- 
gens, subleevis. 
Hab. rocks near the falls of the Yosemite Valley, Bol. 
Distinguishable from O. anomalum, Hedw., which this species most resembles, 
by its peristome, and from O. Hutchinsie, Hook. and Tayl., by the areolation of its 
leaves and other indicated characters. Appears also nearly related to Q. consimile, 
Mitt. But the author says of his species: theca siceitate piicata, ciliis simplicibus @quilon- 
gis, calyptra ramentosa, characters at variance with those of our species.
