i88 NATIVE BRITISH ORCHIDACE^ 



Var. pulchella. New Forest, Teesdale, Wales, Scotland, including the Shetlands 

 (Druce, B.E.C. p. 523 (1921)). 



Var. alhiflora. New Forest (rare). I saw two or three plants in two locaUties 



there in 193 1. 



Orchis incarnata was included by Linnxus under 0. latifolia in all his works up 

 to the ist ed. VI. suecica (1745) and Sp. pi. (1753), but in the 2nd ed. Fl. suecica, 

 he separated it from O. latifolia as follows: "Prscedenti [i.e. 801, latifolia] 

 simiUima, a qua differt. Fohis pallide viridibus immaculatis ; nee saturate 

 viridibus immacvdatis. Caule dimidio breviore. Bracteas vix flore aut germine 

 longioribus. CoroUis paUide incarnatis; nee rubris. Fetalis dorsahbus totaUter 

 reflexis; nee tantum patuHs, nee maculatis. Nectarii labium structura convenit". 

 He did not reaUse the existence of colour-varieties other than the flesh-coloured one 

 from which he derived its name. Reichenbach p. reversed Linnxus' action and 

 presented incarnata as the type of O. latifolia, giving the new name O. majalis 

 to the spotted marsh orchid which was the type of O. latifolia L.;^ but his son 

 rejected this change of names and types, and figured and described true incarnata 

 as such.^ In the earher British Floras O. latifolia was mainly incarnata (including 

 pratermissa). Babington was the first to separate it from O. latifolia as a variety,3 

 and later as a distinct species.'*

Fertilisation. As in Orchis generally. The flowers are well visited, and many 

 seed-capsules are produced. I saw it visited near Christcliurch, Hants., on May 14th, 

 191 8, by Bombt/s lapidarius and B. terrestris. The former had two pairs of pollinia on 

 the front of the head. On the spikes on which I took them the polUnia had been 

 removed from six flowers, and three stigmas had been pollinated in one case, and 

 two pairs of pollinia removed and two stigmas fertilised in the other. On May 28 th, 

 191 8, I saw the v^n^ty pulchella, near Hamworthy Junction, visited by a Bombtis, with 

 a pair of pollinia on its head, which I think was B. agrorum F. On June 17th, 1919, 

 some spikes of O. incarnata in a vase on a verandah at Guildford were visited by two 

 humble-bees, who took no notice of spikes of 0. pratermissa in the same vase. 



ORCHIS INCARNATA x LATIFOLIA 

 PI. G, fig. 6 (p. 191). X Orchis Aschersoniana Hausskn. 

 Stem not so hollow as in 0. incarnata. Leaves erect, linear-lanceolate, tapering from 

 base, sometimes with ringed spots, sometimes with many small dull purple spots, 

 rarely unspotted, slightly concave at tip, sometimes rather bluish green, sometimes 

 narrow (11 mm.). Spike rather short, about 6 cm. Flowers resembling those of
