Papaterace^. 



Meconopsis cambrica, Yig. 1300 feet. — Several specimens in a gnlly 

 on King's Mountain. Yery sparingly on the north side 

 of Ben Bulben. 



PrarAEiACE^. 



Fumaria officinalis, (?) Linn. — Specimens gathered in a cultivated field 

 north of Sligo : too imperfect to identify with certainty. 



Cetjcifee^. 



Sinapis arvensis, Linn. — Common in cultivated fields. 



,, alba, Linn. — Frequent. 

 Sisymbrium officinale, Scop. — Roadside near Kinlough. 



,, alliaria, Scop. — Eoot of cliffs over Colonel Whyte's 



Cottage in Glencar. 

 Ca/rdamine pratensis, Linn. 1600 feet. — Common. 



,, hirsuta, Linn. — Glenade, &c. ; not common. 

 Ca/rdamine sylvatica, Link. — Common. 



Arabis petrcea, Lam. 1330 feet. — Very rare. In one place on the 

 cliffs of Glenade there are about fifty plants, some 

 growing in inaccessible places. Corry's height for this 

 species, 1850 feet, would indicate a different locality, 

 but there is a query prefixed to the species in his original 

 marked London Catalogue. 

 ,, hirsuta, Brown. — Common on the cliffs. 

 Barbarea vulgaris, Brown. — Roadside near Milltown. 

 Nasturtium officinale, Brown. — Common. 



Cochlearia alpina, Watson. 1900 feet. — Frequent on cliffs at a 

 high level. A form with the pods globose, and not 

 distinguishable from Cochlearia officinalis, is common. 

 Draba incana, Linn. 1950 feet. — Common all over the cliffs. 



,, var. confusa, Ehrh. — This form has stellate hairs on the 



pods, and it was only gathered at Annacoona, over 

 Gleniff. 



Draba rupestris. Brown. — First recorded by Withering as plen- 

 tiful " on the limestone mountains of Sligo and Leitrim." Sub- 

 sequently by the late Dr. Moore in the Journal of Botany (vol ix., 

 p. 299), as having been gathered on that part of the Ben Bulben 

 range known locally as " King's Mountain," when he was botaniz- 

 ing there in company with Prof. Thisleton Dyer, in the last week 

 in May 1871. Only two small plants were then gathered, one of 

 these is now in the herbarium of Mr. A. G. More ; the other I 

 have not been able to trace. A careful but unsuccessful search was 

 made for JD. rupestris, but we only obtained some dwarf forms of D. 

 incana, not unlike D. rupestris at first sight. On comparing Mr. More's
