8 ON CALIFORNIAN MOSSES. 



39. GRIMMIA leucophaea Grev. 



A variety with the hair-point of the leaves more strongly dentate, and the teeth of the 

 peristome more irregularly divided. On granite boulders ; common. 



40. KACOMITRIUM canescens Brid. 



It is also a variety differing from the European form by a narrower areolation nearly 

 continuous near the base of the leaves and not papillous ; by the hairy pellucid point of 

 the leaves, dentate only, but not rugulose ; by the cylindrical-ovate capsule of a lighter 

 color. The plants are generally stronger, and the leaves longer. This variety, by its 

 areolation, bears to the normal form the same relation as this bears to the variety 

 ericoides with more papillous and rugose leaves. On shaded rocks at the banks of a 

 creek, Marin County. April. 



41. HEDWIGIA ciliata Ekrh. 



On stumps of Sequoia viridis, California. I have never seen this species grow- 

 ing on wood. There may have been a change of labels. This new habitat is remarkable 

 indeed. 



42. BRAUNIA Californica Spec. nov. Monoica, laxe caespitosa, fusco-lutca. Caulc primario subrepcnte 

 valde diverse ramoso; ramis erectis gracilibus julaceis apice incrassatis duris, vel simplicibus vel irregulariter in- 

 novante ramosis, ramulis brevibus rarius flagellifcris ; foliis in sicco appressis, humiditate apertis, ramorum apice 

 subsecundis, e basi subdeeurrente oblongo ovatis, apice brevi lanccolatis, pellucide acuminatis vel acumine lou- 

 giori flexuoso Isevi peliferis enerviis, margine versus basim superno que reflexis, medio revolutis ; areolatione 

 basilari elongata, alari quadrata, superiori ovato-polygoaa pulcherrime seriatim catenulata distincta, utraque pagina 

 prxcipue externa papillosa; Perichaetialibus brevioribus laneeolatis-acutis raro pellucide brevi acuminatis; eapsula 

 in pedicello semipolicari pallide luteo sinistrorsum torto, turbinata ore dilatata nuda; operculo conico-elongato 

 obtuso recto. 



By the general appearance and color of the stems, this species resembles the slender 

 form ofHedwigia ciliata, the leaves being always terminated by a diaphanous, 

 sometimes very long hairy point. The straight hard branches are variable in thickness, 

 generally inflated at the innovations, and below the short flowers bearing branches. The 

 male flowers, like the female, are at the top of one of these branches. Their many-leaved 

 floral envelope has oval, short, pointed leaves, the point also diaphanous. As in the other 

 species of this genus, the vaginula is very long, descending to the base of the fruit-bearing 

 branch. The capsule, of a light brown color, is, when deoperculated, exactly top-shaped, 

 broad-mouthed. The dark yellow calyptra split on one side is long, and incloses the 

 whole capsule till its maturity. Grows in large patches on metamorphized rocks in Mount 

 Diablo, up to 3000 feet. April, 1863.

Santa Cruz Mountain, 4000 feet. Prof. Brewer, legit.
