BOTANICAL REPORT. 255 



wall offers little encouragement for such plants. In drawing xip 

 his list for Mr. Watson, ]\Ir. Pascoe included Aspoii/a cynmichica 

 without heing able to cite a single locality for it. Miss Moff'att 

 is also unable to submit a voucher specimen for the ''Common 

 near Biscovey." 



Filago apiculata, G. E. Sm. This must be deleted, Mr. 

 Winn having recently assured me that he and another critical 

 botanist have recently gone over his specimens, and they are 

 both agreed that what were recorded as F. apiculata must go 

 down as F. gcrmanica. Mr. Eichards' Poltesco record is not sup- 

 ported by specimens. 



Hieracium crocatum, Fr. This is another case illus- 

 trating the value of voucher specimens. At my request Mr. 

 Winn has submitted his Gwennap Pit specimen of what he has 

 been calling II. crocaium to a specialist, who at once fixed it as a 

 triflingly abnormal example of II. umhellafum. II. crocatum is 

 distinctly a north-country plant, Merionethshire marking its 

 most southern limit. 



Cuscuta europsea, T.inn. Adhering to the rule laid down 

 at the head of this section, that every critical species recorded for 

 Cornwall must be supported by voucher specimens, or have been 

 checked or verified by another botanist, I must place the great 

 dodder in the present list of exclusions. 



Rumex maritimus, Linn. The remarks offered on the 

 preceding species also apply here. There is an old Devonshire 

 record for the plant, so old, in fact, and unreliable, that no use 

 was made of it for the second edition of " Topographical 

 Botany." 



Poa Alpina, Linn. The only published Cornish record for 

 this grass is for Eastern Green, Penzance, by the late Mr. W. A. 

 Glasson, in the "Transactions and Report" of the Natural 

 History and Antiquarian Society of Penzance, 1889-90. This, of 

 course, is a native of the mountains of Scotland and the north of 

 England, and one would as soon expect to find a Moa or a Dodo 

 in an aviary as Poa alpina, growing on the sunny slopes of 

 Mount's Bay.
