192 2. Notes. 05 



Ornithogahim umhellatum L. 5— Though an obvious garden outcast, 

 has been estabUshed and apparently increasing for several years 

 by the cliff path by the Needles, Howth, 



Opht'vs apifera Huds, This orchis is apparently sufficiently rare 

 for a new station to be welcome. In July 1922 my friend Rev. 

 H. Jennings, rector of Finglas, showed me seven or eight good 

 plants scattered over some hundred j'^ards of broken ground 

 in the disused quarries near that village. 



Polypogon wonspeliensis Desf. 4 — Several plants by roadside at 

 Cabra, near the level crossing to Cardiff's Bridge, 1922. 



Poa compressa I.. Mr. Stelfox's Rathmines station has survived 

 the concreting process referred to by him in October 1920, and 

 is now flourishing (see also below). 



Ceterach officinaruni Willd. 8 — -About a quarter of a mile north of 

 Glencullen crossroads, at 950 feet. Mr. Colgan says of this 

 species " ascends to 600 feet at Ballinascorney."

The following botanical notes may be of interest. Last week I 

 gathered Ensyniiim cheiranthoides (easily distinguished by the trifid 

 hairs on the leaves) in the grounds here. As the plant was growing 

 near the chicken-run it was no doubt introduced with corn seed. I see 

 by the new supplement to the " Flora of the N.E." (in proof) E. cheiran- 

 tJioides has not been reported from Co. Do\vn before, and only once from 

 Co. Antrim. In a field at Portnacoe, Co. Down, I found Orobanche 

 minor growing in considerable quantity on the White Clover with which 

 the tieid was sown ; and near Donegore Church, Co. Antrim, Chenopodium 

 Bon US- Hen Hens.

Poa compressa survives ! 



In spite of the treatment meted out to this plant in 1920 (see Irish 

 Nai., vol. xxix., p. 108), a small tuft of it was seen by Miss Knowles on 

 the wall in Grosvenor Place, Rathmines, last year. This year it has 

 almost recovered its former luxuriance, but there is now only one clump 

 visible instead of several.
