BOTANY. 



Some Rare Plants in Mid Cork. 



The following plants were noted at Currabinny last summer : — 

 Fnmaria Borcei,]ov6.. [fide H. W. Pugsley), plentiful on the shingle near 

 the pier, f Vicz'a tetraspervia, Moench, abundant on the shingle, roadside, 

 and waste ground about the pier, growing with V. hirsuta, Koch, and 

 thoroughly established, Picris echioides, Linn., in some plenty on the 

 shingle with the above ; this plant does not appear to have been noticed 

 in Mid Cork since 1854 {vide •' Cyb. Hib. ," 2nd Ed., p 198).

The Leaf-marking of Arum maculatum. 



I have made no close study of the plant, but from Yorkshire to Surrey 

 and Sussex I have noted that it has generally /Vrt;r/('-</^//^(i leaves; whereas 

 in Ireland its leaves are mostly green and unspotted. In England green- 

 leaved forms without black spots seem to me to be rare, and the converse 

 seems true in Ireland. 



In England the spath is often spotted as well as the leaf, but I have 

 never seen a spotted spath in Ireland.

Our Alien Flora. 



Mr. S. T. Dunn, lately appointed Botanical Superintendent in Hong 

 Kong, has issued "A preliminary list of the Alien Flora of Britain." 

 The list includes " firstly, all the presumably non-indigenous species 

 hitherto recorded as growing spontaneously in the British Isles, and 

 secondly, all those species which, though probably natives, have so far 

 been exclusively or chiefly recorded in Floras in their non-indigenous 

 localities." The first class, distinguished by Roman type, includes our 

 cornfield weeds, ballast plants, casuals, and escapes down to Syringas, 

 Rhododendrons, and Laburnums. In the latter class, printed in italics, 

 it is a surprise to find two of our famous Irish Heaths, Erica niediierranea 

 and Dabeocia polifolia, as well as many such widely distributed and 

 abundantly recorded natives as Saxifraga tridadylites and Erodiitm cicu- 

 tarium. Mr. Dunn's italicised group evidently refers to native plants 

 which have been recorded from localities where they are non-indigenous ; 

 but his definition of the group does not fit his list. As a first gathering 

 together of our alien flora, Mr. Dunn's effort will be welcomed by all 

 field botanists.
