1885.] THE FOREST FLORA OF CARNARVONSHIRE. 359 



* Cephalantliera grcmdiflora. I have fouud a few specimens of this 

 rare and beautiful orcliid in a sandy or stony wood on Tygwyu 

 farm, near Aber. 



Listera ovata. A common woodland plant in Penrhyn Park. Extends 

 to 300 feet above sea-level. 



Z. cordata. Sparingly in open woods and fields near Llanrwst. 



*Spirantlics aichcmnalis. Plentiful amongst scrub oaks on the hillside 

 near Conway. 



Orchis Morio. Very sparingly distributed. I have found a few speci- 

 mens in a field between two woods near Bethesda. 



0. nutscula. I'lentiful in most woods. 



0. maculata. Common in open woods. 



*0. maculata supcrha. This rare variety I have found on several occa- 

 sions, or at least what I consider equally as good as that sent 

 me under the above name by the late Eev. H. Harper Crewe. 

 It always occurs in company with the marsh orchis (0. lati- 

 folia). 



0. latifolia. I have not fouud this orchid in the woods, but it occurs 

 plentifully in a marsh alongside the plantations between Glasin- 

 fryii and Pentir. 



0. pyramidalis. Local in its distribution, but plentiful in one or two 

 situations. 



0. Gonopsca. Not usually a woodland plant, but it occurs somewhat 

 plentifully in an oak wood bordering a meadow near 

 Bethesda. 



*Halcnaria hifolia. Plentiful in many woods. I have found, on the 

 liills above Tregarth, a variegated form of this orchid. It is 

 reproduced from seed. 



H. alhida. On the outskirts of one wood near Bronydd, at 500 feet 

 elevation. 



*ir. viridis. Sparingly on Bangor mountain. 



*Ophrys apifcra. In the woods at Bodnant, and near Llandudno 

 (local).

 Iris Pseud-acorus. In a woodland lake at Perfeddgoedd, plentiful. 



Amaeyllide.^;. ' 



Narcissus Pseudo-Narcissus (single). Abundant in a wood at Caerhun, 



near Conway.
