"Grimmia Holzingeri Card, et Ther., sp, nova. Minima, tenella, pulvinatula, 

 obscure viridis, inferne fusca. Caulis erectus, 4-6 mm. altus, parce ramosus. 

 ramis interdum attenuatis, subflagellaceis. Folia c6nferta, minima, 0.50-

 ■Cae'tera ignota. This very minute species, resembling in habit the small 

 form of Andreaea jetrophila, is quite distinct from all the European and 

 North American species of Grimmia with muticous leaves by the small size, 

 and the shape and areolation of the leaves. Base of Sperry Glacier, Mt. 



Trilby. 



"Grimmia Mollis B. S. This European alpine moss is reported from Green- 

 land, and should he found at intermediate stations in Canada. Base of 

 Sperry Glacier. No. 17.

 lare Cardot). New to North America. Cardot det. Base of Sperry Glacier. 



Bryum alpinum L., var. denticulatum Card, et Ther., n. var. A forme 

 typica differt habitu graciliore, foliis ovato-acuminatis, brevioribus, margini- 

 bus parum revolutis, superne distincte sinuato-denticulatis, costaque longe 

 ab apice dissoluta. On the way from Holzinger's Basin to the Rim.

"Hypnum Cardoti Ther., sp, nova. Polygamum, olivaceo-viride, molle, 

 laxiuscule depresso-caespitosum. Caulis procumbens vel ascendens, irregu- 

 lariter ramosus, 2-4 cm. longus. Folia remotiuscula, patulosquarrosa, inter- 

 dum subsecunda, e basi constricta anguste decurrente late ovate-deltoidea, 

 subito in acumen angustum breviusculum recurvum protracta, circa 1.5 mm. 

 longa et o.75 lata, marginibus planis fere undique sinuato-denticulatis, costa 

 simplici-bifurcata vel gemella, crure longiore ad medium producto, cellulis 

 laxiusculis linearibus subflexuosis, basilaribus brevioribus et latioribus, alari- 

 bus laxis majoribus subhyalinis. Folia perichaetialia externa ovato-lanceo- 

 lata, breviter acuminata, subintegra, enervia, intima plicata, costata. Cap- 

 sula in pedicello rubente valde flexuoso, circa 18 mm. longo, subhorlzontalis, 

 arcuata, opcrculo convexo apiculato. This species is near H. stellatum Schreb. 

 and H. polygamum Sch. From the first it is at once distinguished by the 

 polygamous inflorescence and the softer leaves with a shorter acumen and 

 a looser areolation. The shape of the stem leaves and of the perichaetical 

 leaves distinguishes it from the small forms of the second species. Avalanche 



Basin.
