OPHRYDE^—GYMNADENIINyE—GYMNADENlA 147 



A form with thick stem, broad spike, and flowers resembUng those of G. conopsea, 

 with a long narrow slender curved spur is figured in the frontispiece, Winchester 

 Coll. N.H. Soc. Kep. 1913-15, and reproduced in B.E.C. PL 10 (1917), as Habenaria 

 Wintoni Druce, but on too small a scale to show any recognisable characters of 

 O. pratermissa. 



GYMNADENIA CONOPSEA x ORCHIS PURPURELLA 



Orchigymnadenia varia Steph. p. and f.^ 



PI. 26 A, figs. 5 and 4 (p. 141); PI. K, fig. 3 (p. 220) 



Three plants growing close together in Arran in early July, 1921, were described 

 by Dr Stephenson' as follows. The tallest was about 20 cm. high, the whole plant 

 yellowish green with narrow unspotted leaves. Flowers larger than in G. conopsea, 

 but the colour, strong scent and long spur clearly showed the parentage of that 

 species. The regular lip-pattern of broken lines, the stout spur rather darker than 

 the flower, and the short spike showed the influence of 0. purpttrella. Dr Stephenson 

 admits that the Orchis parent might possibly have been 0. latifolia, which was present 

 but scarce, but the spur of the latter is paler and more slender, and he considers the 

 balance of evidence to be in favour of 0. purpurella (PI. K, fig. 3). A second form was 

 found, July 9th, 1921, which was nearer to O. purpurella — a slender dwarf plant about 

 10 cm. high with narrow spotted leaves, and a lip very similar to that oiO. purpurella, 

 but scented, and with a long and stout spur, very large in comparison with the size 

 of the flower. Dr Stephenson found two specimens at Teesdale in 1929, 0. purpurella 

 being plentiful there. 



A few specimens were found by me in Teesdale, July 3rd-6th, 1930: 

 (i) Like an unspotted-leaved 0. purpurella, but flowers smaller. Spur curved, more 

 slender, and as long as ovary. 



(2) Leaves spotted. Spike longer (8 cm.) and more slender (22 mm.). Flowers 

 like 0. purpurella but much smaller. Spur slender, as long as ovary (PI. 26 A, fig. 3). 

 Fig. 4 is from another spike. 



(3) Leaves with small spots near edges. Spike longer (8 cm.) and more slender 

 than in O. purpurella, almost as long and nearly as slender as in a fine spike of G. conopsea 

 compared at the time with it. 



(4) Leaves nearly as broad as in 0. purpurella (all the above had narrow leaves) with 

 small spots. Spike cylindrical, narrow (7-5 x 2-5 cm.). Flowers like 0. purpurella, 

 but not so dark-coloured and much smaller. Spur curved, longer and much slenderer 

 than in O. purpurella.
