Below n° 658 in Herb. Kew Mitten has written « Orthomnion 
crispum Wäils. MSS. » There is no specimen of this number in the 
British Museum (except under Y. trichomitrium). M 
At some time or other Carl Müller, who does not maintain 
Orthomnion, issued two plants as #. sub-crispum C. M. and 
M. pseudo-crispum C. M. which (cf. Genera Muscorum, p. 134) he 
evidently considered as closely allied Lo 0. crispum. Herr Loeske 
© has kindly consulted C. Müller’s Herbarium at Berlin, and informs 
me that there are no notes or drawings whatever to indicate the 
characters on which M. sub-crispum was intended to be based, a 
and there is nothing but the spécimens themselves to rely upon. 
M. sub-crispum was founded principally or entirely on à sterile 
plant, of which a specimen exists in Schimper’s Herbarium at Kew, 
labelled « Sikkim, Kurz, 2452 », and which Schimper also distri 
buted as « M. sub-crispum, teste C. Müller ». I have examined one 
or two specimens of this, and have compared it carefully with 
n° 658 Hook fil. & Thomson, and I have no hesitation in saying 
that it cannot be separated from ©. crispum. There are certain 
characters presenting some variation, the form of leaf base, 
decurrent or non-decurrent, the width of the border, and the size 
‘of the cells : but — apart from the fact that I have no knowledge 
whether these were the characters on which C. Müller based his” 
species — they all vary within the limits of a single tuft, and ther 
is certainly nothing stable:on which Lo found a species or even à 
variety. The accessory leaves, moreover, quite agree with those 
of O. crispum. M. sub-crispum G. M., MS. must therefore be treated 
as a synonym of O crispum Wils. Re 
It is quite otherwise with M. pseudo-crispum C. Müll, nov 
spec. (in herb. et in lit. ad Levier, Nov 1894), of which Dr Levier 
has distributed specimens from several localities. Of this | possess 
through Dr Levier's kindness two spécimens, including one from. 
the original type, leg. W. Gollan; 2 Jun. 1881, in monte Nag Tiba, 
Mussoorie, N. W. Himalaya, det. C. Müller. [have also examined 
the specimens at Kew and the British Museum. There can Lthink 
be no doubt at all that these belong to M. rostratum ! The diffe-
