ham plant the ligules are streaked with brown on the under side, and that the anthers 

 are brown — characters which Linnaeus, in contrasting Trag. orientalis and pratensis in 

 his ' Species Plan tarum,' expressly states that the former species does not possess ; * 

 moreover, the marginal achenia in our plant are muricated with tubercles, not with 

 scales, as those of Trag. orientalis are stated to be by Koch.f 



We may tale this opportunity of mentioning our ^belief that the common plant of 

 our meadows and pastures is Tragopogon minor of Fries, Nov. 2nd ed. 291, in which 

 the involucre is about twice as long as the florets, and the peduncles much swollen im- 

 mediately beneath the flowers ; at least this is the plant we have generally met with. 

 Ray's remark that in Tragopogon the rays of the calyx are longer than the flowers,^ 

 would seem to favour this opinion ; Relhan also observes that the corolla is sometimes 

 shorter than the calyx. § We should be glad to receive communications on this and 

 other doubtful points connected with the history of British plants. — Ed^ 



Art. XIII. — Notice of Plants gathered in the vicinity of Aherystwiih^ 

 Cardiganshire. By Edwin Lees, Esq., F.L.S., &c. 

 The vicinity of Aberystwith is composed entirely of the clay slate 

 formation, and consequently there is little variety of soil; but it may 

 perhaps be more interesting to the collecting botanist, to class the 

 plants met with according to the habitats affected by them, rather than 

 to give them in one catalogue. They may be more easily sought too 

 by this plan, and a long detail of the exact locality is hereby avoided.
