OPHRYDEjE—GYMNADENIINyE—CCELOGLOSSUM 127 



Darwin thouo-ht that an insect might visit all three nectaries, but this is improbable 

 in view of the abundant contents of the spur. An insect alighting on the opposite 

 side of the lip would similarly remove the other poUinium. 



I can find no record of what insects visit this species, but on the Col de Granier 

 above Chambery, on June nth, 1924, my wife saw a long slender insect with black 

 thorax, orange abdomen and black tail, subsequently identified at the Paris Museum 

 as Tenthredopsis tarsata F., visit two or three flowers of C. viride, and emerge with 

 poUinia on its head. She caught it in her fingers and put it into a match-box. The 

 poUinia were attached to the head between the eyes and beneath the antennae. Below 

 were the remains of another pollinium with most of the pollen gone.

Three types of this hybrid have been found in England : 



(i) A form first found in 1909 by Mr Jackson near Winchester, and described by 

 the Rev. R. Quirk as follows: "Much shorter than G. conopsea. Flower-spike either 

 pink tinged with green, or dull livid red. Corolla pink or purphsh, but overspread 

 with a marked tinge of pale yellowish green. Bud blunter and squarer, as in C. viride. 

 Sepals and petals not connivent in a helmet, but open and spreading, exposing the 

 column, thus differing from both parents. Spur shortened, but not to the small blunt 

 pouch of C. viride. Bracts as a rule larger and more leaf-like, as in the latter. Described 

 from an indifferent specimen, no good specimen having been found this year".i 

 (Text-fig. 10 A.) 



To the above may be added the following description of a cut spike sent to us, 

 July 17th, 1917, by Donald Lowndes, then a boy at Winchester College (PI. 23 A). 

 Stem about 10 cm. tall. Lower leaves not seen, upper leaves several, erect, bract- 

 Uke, linear-lanceolate, acute, the lower bracts exceeding the flowers, the upper the 

 ovary. Spike cylindrical, dense, flowers small. Sepals sub-equal, pale lilac rose, in 

 some flowers greenish tinged with rose, the lateral spreading incurved, not recurved 

 at the tip as in G. conopsea. Petals oblong, slightly longer than sepals, nearly erect, 

 in some of the lower flowers forming a loose hood with the upper sepal. Lip broadly 

 oblong, the mid-lobe tongue-shaped, broad, shghtly emarginate, the side-lobes barely
