PHILONOTIS. 29; 



slightly homomallous or erecto-patent, narrowly ovate-lanceolate 

 finely acuminate, not concave nor plicate, margin plane or slightl] 

 and very narrowly recurved, nerve rather narrow, usually vanishing 

 in apex ; cells moderately lax, papillose. Perigonial bract! 

 squarrose or even slightly reflexed, rather long, acute ; nervi 

 thin, rather indistinct, usually vanishing below apex. 



Hab. In clefts of rocks and beside springs ; rare ; male flowers only found ii 

 Britain. 



This pretty little plant appears to me fully as deserving of independent rank a 

 any of the forms of the group. The small, uniform leaves, mostly with plane margin 

 and quite free from plicae, show characters which, if not very distinct, appear to b 

 unusually constant, while the perigonial bracts are certainly more distinct from thos 1 

 of P. fontana than are those of any other of the allied plants. 



There has been much confusion as to the name P. capillaris, in great measur* 

 owing to its having been applied to several plants which have afterwards provei 

 distinct ; Husnot has separated two forms, P. capillaris Lindb. with the perigonia 

 bracts erecto-patent, shortly pointed, with nerve reaching apex, and P. Arnelli 

 Husn. with the perigonial bracts squarrose, even slightly reflexed, and much mor< 

 longly and finely acuminate with the nerve excurrent ; to these Philibert (Rev. Bry 

 1894, p. 8) has added another, P. Ryani, somewhat intermediate in the perigonia 

 bracts, but differing in the leaves. Our British form, judging from male plants whicl 

 I have gathered in Skye and in the Lake District, stands somewhat midway betweei 

 P. Arnellii and P. Ryani, the perigonial leaves are distinctly squarrose or even ; 

 little reflexed, longer and more tapering than in P. capillaris (sensu Husnot) but les 

 finely acuminate than in P. Amelia, and with the nerve usually vanishing below th 

 apex. It seems probable that after all these forms will eventually have to be re 

 united. It must be remembered that the perigonial bracts are always erecto-paten 

 for some time, and their direction must be determined from quite mature specimens 

 The above description refers to our British plants, so far as I am acquainted wit] 

 them, alone. The Scotch specimens referred to above have the inner perigonia 

 leaves a little less acuminate and acute than in the others I have examined. 



71. BREUTELIA Schp. 



Tall, robust plants, with tomentose stems ; branches irregular 

 Leaves spreading and squarrose, plicate ; cells narrow. Capsulf 

 more or less pendulous , striate ; peristome as in Bartramia. 



A large genus of fine plants, the following species being th< 

 only European representative, and though not uncommon with us 

 a great rarity on the continent. 



1. Breutelia arcuata Schp. (Mnium arcuatum Dicks. 



Breutelia chrysocoma Lindb., Braithw. Br. M. Fl.) 



(Tab. XLI. F.). 



Tall, robust, 3-6 inches long, bright or golden green, in largi 

 loose tufts. Stems covered with dense brown tomentum, oftei 

 decumbent, forked, or with alternate branches, or with somewha 

 whorled branchlets below the flowers. Leaves large, equal ii
