﻿MOSSES FROM MiTTEN's HERBARIUM 105 



lateralia uno margine late, superiora et inferiora marginibus 

 ambobus angustius inflexis, magna, 3 mm. longa, medio folio i 

 mm. lata, late oblonga, basi paullo dilatato ad insertionem angus- 

 tiore, supra late rotundata apiculata, apicem versus grosse inaequa- 

 liter dentata; madida leniter striata, sicca pluries profunde plicata. 

 Costa infra valida, supra medium cite attenuata, longe infra 

 apicem soluta, opaca, dorso laevis. Rete perdensum, cellulis 

 medianis anguste lineari-rhomboidis, omnibus parietibus tenuibus, 

 eae apicem versus breviores, latiusculae, regulariter rhomboideae, 

 circa duplo longiores quam latae; infra minime mutatae, paullo 

 tamen elongatae, angustissimae, ad angulos extremos tantum 

 paucae paullo latiores, bistratosae, obscurae, maculam minimam 

 alarem inconspicuam opacam formantes ; omnes densissime chloro- 

 phyllosae, laeves. Folia stipitis squamiformia, infima aeque ac ilia 

 surculorum baculiformium acuminata squarroso-reflexa, mem- 

 branacea. 



Cetera ignota.

Brotherus writes that this — unless it should be Th. neckeroides 

 (Hook.) B. S. G.^is certainly a new species. I have examined 

 the type of Hypnum neckeroides \n the Hooker herbarium at Kew; 

 it has non-complanate leaves, the nerve sharply toothed at back, 

 and reaching nearly to the narrowed though subobtuse apex; 

 while the upper cells are small and rounded. It is a quite different 

 plant from the present. Moreover it appears that Menzies' plant 

 was erroneously stated to come from "Dusky Bay, N. Z." It 

 was really one of his North American gatherings, and the species 

 is, so far as is known, confined to the west coast of North America. 

 In any case it has no near relationship to our species, which is very 

 closely allied to Th. arhusculans (C. Mull.) Jaeg. from Chile and 

 western Patagonia; in fact Dusen's specimens of that plant only 

 differ in the less plicate leaves, the thinner nerve, and more 

 pellucid non-chlorophyllose areolation— the latter character pos- 

 sibly depending partly at least on the greater age of the specimens. 

 Dusen's specimens, however, show none of the rather striking rod- 

 like shoots from which the present plant is named. These are 

 peculiar; those on the few stems I have seen are perfectly straight, 

 up to an inch in length, and terete except for the minute squami- 

 form leaves.
