THREE NEW SPECIES TO ''CYBELE HIBERNICA" 

 AND "IRISH TOPOGRAPHICAL BOTANY." 



BY G. CI.ARIDGH DRUCE, M.A., F.L.S. 



Recently Professor Gliick of Heidelberg, the author of 

 Biologische iind Morphologische Untersiichtingcii Hber Wasser- 

 7ind Stimpfgewachse, 1905? and whose much more elaborate 

 work on the same subject is now in the press, has been stay- 

 ing with me. He went through many of the aquatic plants 

 in my herbarium, w^here he detected three species new to the 

 Irish works mentioned above ; they are : — 



Utricularia ochroleuca, Hartm. — I gathered this near Kylemore, 

 Galway, in 1S75. This has been somewhat doubtfully recorded for 

 Scotland, but we lacked till now positive identification of a specimen 

 from the British Isles. 



U. Brcmll, Heer. — Near the Gap of Duuloe, Co. Kerry, where I 

 found it also in J875. This again has been often recorded, but the 

 specimens have been flowerless,, and so the identification has been 

 quite conjectural. M}' specimens have good flowers. The flat, not 

 curved lips easily distinguish it in the living state from U. ininoi\ 

 L. The suggestion which I gave in my British Plant List that 

 ochroleuca (following Hartm an) is a hybrid of V. //n'nor and U. intermedia^ 

 is untenable, since it occurs in areas from which the latter is absent, 



Elisma natans, Buchen. — This, although recorded for Ireland, is 

 rejected by the authors of the Cybele Hibernica, and doubtless with 

 good reason, as the creeping form of Echinodorus ronunculoides. 

 ■ Eugelm., is often mistaken for the true plant. But Professor Gliick, 

 who has made especial study of the barren forms of this group, 

 unhesitatingly refers my barren specimens from Killarney, gathered 

 by me in 1875, and from Dunbeg Lake, Co. Clare (Bolton King) iu 

 1882, to that species. 



Allsma Plantago-aquatica, L., forma natans,— Toome Bridge, 

 Co. Antrim.

BOTANY. 



Draba incana in County Antrim. 



A botanical visit which I paid to Torr Head, in the extreme north- 

 east of County Antrim, on 12th July last, resulted in the finding of 

 Draba incana, Linn. This is a new record for the county, and a notable 

 extension of range iu Ireland for the plant. It grows on white limestone 

 rocks, at an elevation of about 900 feet. Immediately associated with it 

 were Arabis hirsuta. Geranium liicidii.'ii, and Cystopteris fragiiis.
