Habenaria (bifolia) chlorantha, Bab. 
Provinces 1 to 16. Cornwall; Briggs.—Skye; Lawson. 
Syn. 1055. Cyb. ii. 429. iii. 512. Dr. Boswell Syme reports 
that intermediate forms are seen on the Reigate hills, between 
chlorantha and eu-bifolia. Mr. Bentham, after observing that “the 
extreme forms have been distinguished as species” goes on to 
declare that ‘every intermediate may be observed between the 
broad and the narrow forms.” Since my own attention was 
particularly called thereto, IT have not enjoyed an opportunity to 
examine the chlorantha in its wild localities. Mr. Darwin contends 
that the two are quite distinct from each other; being fertilised by 
different insects in a different way. Dr. Hooker, one of the most 
able and most earnest among the supporters of the Darwinian 
theories, nevertheless only ventures so far as to give them the 
dubious grade of “ sub-species.” Assuming intermediate forms in 
the plants, how are they produced? It does not appear that 
Mr. Darwin can shew intermediate insects to correspond; he has 
them for the extremes only. If the intermediates are half-breeds, 
cross-bred between the two extreme forms or “species,” the same 
insect should be on visiting terms with each parent, and the pollen 
of one be capable of fertilising the other parent. If not half-breeds, 
the machinery of different insects for the two ends of the series 
only, seems an elaborate non-necessity, until insects are found 
specially for “every intermediate.” 
Ophrys (aranifera) fucifera, Sm. 
Provinces - 28. Dorset. Wight. Hants? Sussex. Kent. 
Syn. 1061. Cyb. ii. 434. iii. 513. O. aranifera (limited) in 
provinces - 84; counties of Kent, Oxford, Suffolk, Cambridge 
and Northampton; very doubtfully in Somerset, Salop, York. 
But it is remarked in English Botany that the two segregates 
“can scarcely be separated.”
