both dull pink and yellow in tlie flower. Fig. 2 is from a Cardigan- 

 shire form with purple colour. The purple in some forms is darker 

 than this. Fig. 8 is the pale yellow form common at Kidwelly. 

 Fig. 4 is another Kidwelly form, with Howers of a rich deep maroon 

 or mahogany-red. This form is sometimes tall, sometimes dwarf, 

 and when dwarf comes under the var. duneiisis of Druce. It is 

 possibly a crossing of this form with the pale yellow one which pro- 

 duces the colour shown in fig. 1. Fig. 24 (Shrewsbury) is the typical 

 rose-pink form found in various parts of England. 



i^igs. 5-8. 0. PKJiiTEinrissA. Figs. 5 (Aberystwyth) and G 

 (Kidwelly) show the typical form of this species, with the lip both 

 actually and ]iroportionately broader than in O. i)tcarnafa, milch 

 flatter, and with a less distinct pattern, composed of dots and slight 

 lines. The throat is not so wide as that of O. incarnafa. Sepals 

 more or less erect. Colour-range confined to the ])urple to white 

 series, with variations in the du'ection of magenta, red, and pink, but 

 never the curious reds and yellows of man}^ forms of O. incarnafa. — 

 Fig. 7 is from a plant of a form of O. pra-terinii^sa from Towyn. 

 It shows the neat fiower and lip, the ricli colour, and a heavier pattern 

 than is usual in O. prcefenuissa, but which is not like that of 

 O. incaniata. It should be observed that this form \QYy decidedly 

 comes under O. prcetermissa from its broad flat-lip (and also its 

 leaves), but there is also a somewhat similar O. hicarnata var. 

 pulchella, with which it should not be confused. — Fig. 8 is a pale 

 form from Kidwelly, of which we found several examples. The lip 

 is not so broad as in the other forms, the patterns being very typical 

 of O. prcetermissa. 



Fiys. 9 and 10. O. puepukella. Fig. 9 is the Aberystwyth 

 form, fig. 10 that from Hawkshead. Both show the erect sepals and 

 fairly wide throat, and the purple colour. The lip-])attern is fairly 

 heavy but irregular, and (juite differs from that of either typical 

 O. incarnafa or O. lafifolia. The lip itself is more definitely 

 trilobed and less purely diamond-shaped in the Hawkshead form. It 

 should be noted that fig. 9 shows an extreme exani})le of the diamond, 

 many of the flowers of the Aberystwyth form being more like fig. 10, 

 though of richer colour; the Hawkshead form, too, may be more like 

 fig. 9 sometimes, or in other cases verging more towards 0. prcefer- 

 missa. The rich colour of the Aberystwyth form is altogether too 

 deep and brilliant to be rendered in pamt, and the figure must be 

 supplemented by the imagination, being as near the reality as 

 we could make it. 



Figs. 18-16. O. LATIFOLIA. Under this species there are at least 

 six groups of forms to he roughly distinguished, altlunigh they run 

 into each other. The Plate sliows examples of :^our of these. All 

 have a broad flat lip rather incurved at the edges, more or less erect 

 sepals, and a wider throat than that of O. ericeforum. The typical 

 forms have a heavy line-pattern also, be their colour light or dark. — 

 Fig. 13 is from a slender heath-form at Aberystwyth. ^'Y\\(i flower of 

 this is very like the flowei-s of many pale forms of the species, with a 

 dark purple line-pattern on a ])ale ground. Fig. 14 is from a dark 

 fonn growing on Spha;jnHni at Eorth. The heavy line-pattern is
