12. BARBULA vinoalis Brid. 



Very common and variable around San Francisco ; on rocks, boulders, and wet ditches 

 near the bay. May. Var. « has the ramification, form of leaves, &c, of Barbula 

 vincalis; but the operculum and peristome of Barbula flcxifolia limp. Var. /? 

 f 1 a c c i d a Bryol. Eur. has the capsule and operculum of Barbula vinealis, 

 and the long-linear, lanceolate, canaliculate, open-reflexed, loosely-imbricated leaves of 

 Barbula flcxifolia. This variety is apparently the equivalent of Barbula e 1 a t a 

 G. MUll. Same habitat as the normal form. 



13. Barbula flcxifolia Hampe he. cit. 



The characters separating this species from Barbula vinealis arc, 1st. The 

 leaves crisped when dry, squarrosc-reflexed when humected, with revolutc margins. 2d. 

 The somewhat narrower, dark red capsule, with a longer operculum. 3d. The longer and 

 more twisted teeth of the peristome, and their red color. These last characters are un- 

 reliable, the teeth varying in color, and being more or less twisted even on the same 

 specimens, according to the age of the capsule. The characters taken from the leaves are 

 also unreliable, and as this moss covers the sand along the shores, and in the vicinity of 

 boulders covered with Barbula v i n e a 1 i s, these differences, I think, may be ascribed 

 to variations from change of habitat. 



14. Barbula virescens Sp. nov. Inflorescentia, ramifieatione priori proximo, differt: Caule longiori, 

 inferno brunco, supernc arnoeno pallida vircsccnte ; foliis longiorlbus c basi lancoolatis, margine usque ad apicem 

 revolutis, undulatis, arcolatione duplo laxiori, distincta, arcolis ovalibus; periob.8Gtialibus apertis ; opereulo brcviori, 

 annulo latiori. 



Tins species is intermediate between Barbula f 1 e x i f o 1 i a Hmjp. and B a r b u 1 a 

 scmitorta Sul., two species already closely related. From the first it differs essen- 

 tially by the areolation ; from the second, by the revolute margin of the longer leaves, a 

 longer arid more twisted peristome, and a broader basilar membrane. On rocks, Redwood 

 and Oakland, near San Francisco. 



15. Barbula artoearpa Spec. nov. Dioiea, compaete csespitosa. Caule gracili, brcvi, subsimpliei. 

 Foliis inforioribus brevibus, e basi ovata lancoolatis, ncrvo valido percurrcuto brcvi-subulatis ; superioribus longi- 

 oribus, longius lanceolatos ubulatis ; Perichsetialibus latioribus, basi amplcctentibus supernc coarctatis subulatis 

 ereotisj Arcolatione foliorum compacta illoe Barbulcc vinealis simili; Capsula ovata cylindrica brevi gracili, ore 

 coarctata, opereulo longo rostrato subcurvato; Annulo simplici pcrsistentc lato ; Peristoma dentibus gracilioribus, 

 albidis, semel fcortis. 



Except for its pretty large annulus, this species would agree with B a r b u 1 a g r a c His 

 Schw. which it exactly resembles by the ramification, the form of the leaves and of the 

 capsule. It is also nearly related to Barbula subfallax C. Mull, which has also 

 no annulus, and a shorter basilar membrane. Mount del Diablo, California
