The glaucous color, diminutive size (smallest of the genus), rotund- 

 oval, nearly symmetrical ordinary leaves, and proportionately large 

 stipuliform leaves, appear to indicate a species sufficiently distinct from 

 H. Novce Seelandice.

It appears almost impossible to ascertain what species was intended 

 by Hypnum tamarisci, Swartz (Flo. Ind. Occ), founded on specimens 

 from Jamaica. Specimens with this name, from Swartz himself, in 

 the Hookerian Herbarium, are said (Muse. Exot. t. 35) to be iden- 

 tical with L. rotulata, Hedw., likewise an obscure species; in the 

 Flora Antarctica, p. 117, they are said to be the same as a Fuegian 

 species, now H. didictyon, C. Miill.; and in Flora of New Zealand, 

 p. 118, they are referred to H. laricinum, Hook. Muse. Exot. t. 35, 

 which itself is doubtless founded on two different species, one from 

 the Cape of Good Hope, the other from the Andes of South America 

 — the name laricinum, Hook., being very properly adopted by Taylor 

 and by Muller, for the Cape moss only. Furthermore, Taylor's 

 description (Lond. Jour. Bot. 6, p. 338) of " authentic fertile speci- 

 mens of Hypnum tamarisci, Swartz," agrees accurately with our moss. 

 Hence, the Swartzian species being, to say the least, very obscure; if,
