NOTES ON CALIFORNIA BRYOPHYTES.— III. 

 By Marshall A. Howe. 



DuEiXG the past year a few miscellaneous notes on the Califor- 

 nian mosses and hepatics, — on their distribution, peculiarities of 

 structure, the occurrence of novelties, additions to the state list, etc., 

 — have been accumulated, which are, perhaps, worthy of record. 



Among the plants remarked upon below, Stableria is a genus 

 not before attributed to North America, Pellia Neesiana is new to 

 the hepatic flora of our country, and Blasia piisilla, Cephalozia 

 extensa^ Scapa^iia convexa, Scapania glaucocephala^ Plagiochila 

 asplenioides^ Dichodontium Jiavescens, Tortula viontana^ Tor- 

 tilla ericcefolia, Torhcla angzistata, Dicrayioweisia contermina^ 

 Mnium glabrescens^ Leersia rhabdocarpa, Polytriclnun cojnimme, 

 Brachythcciuvi lamprochryseuni, Brachythechcm vebdinum, 

 Carnptotheciuni tnegaptihi'm^ Amblystegium irrigim-m^ and 

 Hypnum {Lhnnobiuni) psetido-ardicum, are additions to the Cali- 

 fornian list, though two or three of these have probably been known 

 from the state under other names. 



HEPATIC^. 



Cryptoviitriuni tenerum (Hook.) Aust. Thisj^lant having been 

 somewhat imperfectly described by Hooker and Austin, Herr F. 

 Stephani of Leipsic obtaind:! through Mr. O. F. Cook, theu of 

 Syracuse University, a specimen which he described in detail in the 

 Botanical Gazette for February, 1892 (xvii, 58-60). In the course 

 of this description Herr Stephani states that the peduncle is bicana- 

 liculate and that the involucres are monogyuous. Schiftner, too, 

 in Engler and Prantl, Die Natiirlichen Pflanzenfamilien (i, Abt. 3, 

 25), makes use of "Triiger mit 2 Wurzelrinnen" in his key to the 

 Marchantiaceous genera in separating Cryptomitrmm ivom Neesiella 

 (Duvalia). As these observations are not in harmony with the 

 results obtained by us, and as both the characters referred to are of 

 importance in determining the affinities of the plant, we have 

 thought it worth while to subjoin sketches of microtome sections of 

 Californian specimens of Cryptomitriu^n. 



Our material was collected in Fruitvale, Alameda Co., on Feb- 

 Erythea, Vol. V, No. 8 [31 August, 1897].
