476 ORCHIDACEAE 



Native. Pratal and uliginal. Marshes, bogs, wet meadows, and osier- 

 holts. Locally common. P. June-July. 



First record. 0. latifolia [in an aggregate sense], Dr. Noehden, Mavor's 

 Agr. Berks, 1809. 



1. Isis. Wytham. Watchfield. Near Coleshill. 



2. Ock. Marcham, Walker. South Hinksey, Lawson in Herb. Oxf. In 



Hagbourn Moor and many other places, Lousley in Russell's Cat.

 Cothill. Steventon. 



3. Pang. Bradfield, Jenkinson.

 A very narrow-leaved form occurred in osier-beds at Midgham. 



5. Loddon. Blackwater Meadows, Penny. Bulmarsh, Tujnail. Crazey 

 Hill. Thames Meadows near Boulney, Stanton. Coleman's 

 Moor. Hurley. Sandhurst. 



Some of these records mean the aggregate plant. The leaves are 

 often spotless, as in 0. incarnata. The Midgham specimen is a curious 

 long-leaved, tall plant, doubtless caused by growing in an osier-bed. 

 It was sent by the author to the Bot. Exch. Club in 1892. 



At Cothill I have seen a hybrid, 0. lafifolia x maculata, which has the 

 solid stem and spreading leaves of 0. maculata, but the larger flowers 

 of 0. latifolia. 



The figures labelled 0. latifolia in Curtis, Fl. Lond. fasc. v. t. 65. 

 and in Sowerby's E. B. t. 2308. are 0. incarnata. 



0. latifolia is found in all the bordering counties. 



O. maculata, Linn. Sp. PI. 942 (1753). Spotted Orchis. 



Top. Bot. 390. Syme, E. B, ix. loi, t. 1459. Nyman, 692. Fl. Oxf. 295. 



Native. Sylvestral. Woods, thickets, meadows, heaths, and marshes. 

 Common and generally distributed. P. May-July. 



First record. Orchis, site Serapias candido fore, G. 222. Two miles of 

 Oxford from Frier Bacon's Study, Merreit's Pinax, 88, 1666. 

 Gerard's description and figure point to the plant being 0. macu- 

 lata. ' I saw this species near Newbury in 1755 in moist meadows,' 

 Peter Collinson's MS. 

 The flowers vary much in colour, but with us never assume so dark a 



shade of purple as they do in North Britain ; frequently they are very 



pale, and the markings on the flower are sometimes quite obscure. 



Usually they fade somewhat as the flower ages. The spots on tlie 



leaves are also very variable in their intensity of colour. Occasionally. 



as in Wytham, specimens occur in which they are absent. 

 A heath form at Long Moor had very narrow leaves. 

 0. maculata, which is also included in Mavor^s Agr. Berks, 1809, is too 



frequent and generally distributed to need a list of localities. It is 



found in all the bordering counties.
