OPHRYDEjE—SERAPIADINyE—OPURYS 237 



sometimes lanceolate, sometimes oblong-linear, with the edges so much rolled back 

 that they appear tubular, resembling antennas, and are then often dark reddish purple, 

 suggesting a resemblance to those of O. m/sd/era, but too frequent and widely 

 distributed to be due to hybridity. This is probably the same as 0. apijera jS aurita 

 Moggridge,! which according to J. Ruppert is as frequent in Germany as the type 

 (-E.i3. t. 65). Isle of Wight. Surrey! Somerset! In Moggridge's figure (reproduced 

 by Schulze in Orch. Deutschlands) the petals are flat and acute, not rolled into a tube. 

 They are said to be green, sometimes with rosy edges. Plants near Salisbury had 

 green petals. 



Var. chlorantha Hegets. (PL 57C). Sepals greenish white, whole lip yellowish 

 green, usually without markings. Wliite (F/. Bristol (191 2)) calls it forma albida and 

 says it grows in fair numbers amongst the type. About a dozen were seen in bloom 

 at Rancomb, Glos., in 1760.- Hegetschweiler's plants was apparently a diseased 

 abnormal form, with but moderate resemblance to the var. chlorantha as now under- 

 stood, which is apparently due to a kind of albinism. A very similar form of 

 O. arachmtijornns was found by Mr St Quintin at Hyeres. 



Var. Trollii Heg. (Pis. 5 7, 5 8). Wasp Orchid. Lip long, very narrow, tapering 

 into the appendix, which is not turned up behind the lip, markings yellow and brown, 

 very irregular, side-lobes very small. In the excellent figure in White's Flora of Bristol 

 the petals are long and very narrow. In the specimen figured from Bex they were 

 extremely short, as in the continental type of the species. In Hegetschweiler's original 

 plant they were long,4 and the plant looks abnormal, as if diseased, which prompted 

 Prof. Chodat to say to me: "Perhaps there was only one Trollii". It is not a stable 

 form, but varies according to the type of 0. apijera from which it is a sport. Plants 

 occur in some numbers at Winchester, Reigate and Salisbury wliich are intermediate 

 between Trollii and 0. apijera, of which a specimen from the last-named place 

 is figured on PL 57 B. Regel considered it to be the hybrid O. arachnites {Juciflora) 

 X muscifera, but in the English localities given above O. arachnites is unknown. 

 Reichenbach thought it a form of O. apifera due to growth in deep shade, but it is 

 found in the full blaze of the sun. The Winchester form approacliing Trollii may be 

 described as follows: sepals narrower than the type, much reflexed; petals about half 

 as long as sepals, almost tubular, green tinged with red. Lip rather ovate, the apex 

 like the toe of a shoe, from which the appendix projects like a sting, and often shows 

 some tendency to curl backwards ; the side-lobes are short, triangular, rounded at the 

 base, not raised into hunches, densely hairy, the lower side-lobes very shallow, turned 

 down. Markings irregular, sometimes with a shield-shaped darker area at the base 

 of the greenish yellow lip, and a darker blotch at the tip.
