112 ENGLISH BOTANY. 



drate-ovatc, sliohfly convex, with the sides not rofloxed or but sliglitly 

 reflexed, subentu-e, Avith the latei-al lobes usually reduced to projectin"^ 

 humps; the terminal lobe notched with a rather long subrhomboidal 

 or oblong-strapshaped subobtuse appendage in the same plane as the 

 front of the labellum or curved inwards. Anther terminated by an 

 acute reflexed or straight process. 



On chalk downs and by the borders of fields. Very local. Not un- 

 frequent about Folkstone, and said to have occurred near Sitting- 

 bourne; but I can find no trustworthy authority for its occurrence 

 beyond the county of Kent. 



England. Perennial. Summer. 



Very similar to 0. apifera, and, indeed, connected with it by inter- 

 mediate forms; but these, I have no doubt, are hybrids, as they are 

 always found where the two species grow together, but apparently 

 never where one of them grows apart from the other. The difference 

 between 0. apifera and 0. arachnites lies in the labellum, which in 

 the latter is more spread out, broader towards the apex, and with the 

 lateral lobes scarcely projecting beyond the general outline ; the ter- 

 minal appendage is never reflexed under the labeUum ; the colour of 

 the labellum inchnes to brown rather than to purple.

Sepals yellowish-green ; labellum velvety, especially at the margins, 

 with glossy glabrous markings, oval, half-ovoid, with the sides 

 more or less reflexed, nearly entire or slightly 3-lobed at the base; 

 the lateral lobes usually with humps at the base, and points scarcely 

 produced beyond the margins ; middle lobe nearly entire or notched, 

 without an appendage, or more rarely with a minute tooth in the notch. 

 Anther terminated by a short rather blunt straight process.
