40 NOTE ON MYROSMA CANN^FOLIA. 



single locality, " Georgswalde," was known for the Austrian empire. 

 It seems to be known from two localities only in Denmark, bat no 

 doubt is expressed as to its nativity by Lange {Hand. Dunfike Fl. 

 ed. 4, p. 169). At Wexio, Smoland, Sweden, " introduced probably " ; 

 this being a seaport, is there any means by which it could have got 

 there in packing (if even it is so used) ? I have noticed, in the 

 materials that Belgian glass is packed with, some 130 species of 

 plants, some certainly not British. 



In Silesia, Uechtritz accepts it (ScJd. Phaneroyam, 1877, 1878, 

 1881), where he records it from nine localities in that province. 

 It seems to be on record for only one station in N. Italy. In 

 Ledebour's Fl. Bossica, 1853, it is not on record for the Kussian 

 empire, but has since been recorded from two provinces. In 

 Holstein and Schleswig it was recorded as early as 1838, and was 

 found sparingly in 1889 in another station (Prahl, Kr. FL Sch.-Hol. 

 1890) ; but is queried as a native species. 



In Canada it seems to occur very often in "wet meadows," by 

 river-sides. Prof. Macoun remarks: — "Very abundant throughout 

 the prairie region, and northward in the mixed forest country to 

 the Peace Kiver" (Cat. Canad. PL Part 4 (1888)): so that its 

 habitats there are much more various than in Europe. In Gray's 

 Mamial N. U. States, "Low grounds, fields, and roadsides" are 

 given for it. 



I wish that those who have found this phmt in England and 

 Scotland would carefully study its surroundings, and give us a list 

 of the plants it occurs with, and whether any certainly introduced 

 species grow near it. 



The problem British botanists have to work out is whether 

 Jttncus tenuis is an introduced species ; if so, how did it come ? if 

 not, how is it that it has remained so long unfound? Of course 

 I am not taking Don's reported stations into account here, although 

 there are several specimens from him in various herbaria. 



NOTE ON MYEOSMA CANN^FOLIA Linn. fil. 



By J. G. Bakee, F.R.S. 



In 1781, in the Supplementuni Plantarum, the younger Linnaeus 

 described a new genus of Marantncem, from specimens sent from 

 Surinam by C. G. Dalberg, under the name of Mi/rosma. There is 

 a full description of the genus at p. 8, and of the only known species 

 at p. 80, under the name of M;/rosma cannaj'olia. There can be no 

 doubt about the plant intended. Both the generic and specific 

 descriptions occupy more than half a page each, and the two 

 specimens from which they were made are still extant in the 

 Smitliian herbarium at the Linnean Society. The only ambiguity 

 arises from the fact that Linnaeus cites doubtfully a figure of 

 Rheede's {Hortus Malabaricus, xi. p. 67, t. 37) which belongs to 

 Phrynium capitatum Willd., a common Tropical Asian species.
