ORCHIDACE^E 217 



9x3 mm. in broadest part, narrow-lanceolate and rusty-red, turned back 

 towards the ovary. (Measurements taken from Jiving plants.) 



Sandy, grassy plac s in the Var. April-June. The var. anomala Albert 

 (1903) has 3 tubers of which 2 are stalked and the third is often imperfectly 

 formed. It has been found below Hyeres, at Cavalaire, etc. Several of the 

 species of Serapias hybridize easily, e.g. : 



S. triloba Dupuy = S. longipetala x Orchis laxiflora. Tubers 2. 

 Stem erect, 8-12 in. high. Leaves linear-lanceolate, acute, not spotted. Flowers 

 in a short crowded spike, rich magenta. Sepals not united. Lip almost round, 

 with spreading lateral lobes, and crenellated all round the edges. 



Grassy places in fields at the mouth of the Nervia near Ventimiglia, where 

 Mr. Bicknell tells us the parents grow together abundantly. April-May. 



OPHRYS L. 



* Outer divisions of perianth (" sepals ") green or yellowish. 1 

 O. aranifera Huds. (1778) = O. sphegodes Mill. (1768). Spider 

 Orchis. Very variable and with several named varieties. The sepals yellowish- 

 green ; the 2 petals two-thirds length of the sepals. Lip entire, or slightly 

 3-lobed, velvety, pale brown, with yellowish or greenish marks, broad, nearly 

 flat, with no appendage. Column with a short straight beak. Stem some- 

 what zigzag. 



Hill-sides, woods, and borders of fields, common. March-May. 



O. atrata Lindl. (usually considered a var. of the last). The sepals green or 

 slightly tinged with brown or pink ; the petals flat, glabrous, and slightly 

 coloured ; lip without any lighter border, more velvety, the lateral lobes more 

 bossed, the middle lobe with a short appendage. 



Hill-sides and grassy places. April-May. Toulon, Le Luc, La Plage 

 d'Hyeres, Bordighera, San Remo, etc. 



O. litigiosa Camus. Flowers much smaller than the last, 2-6 in a loose 

 spike. The sepals yellow, ovate oblong; the petals linear-lanceolate, yellowish- 

 brown. Lip snorter than the sepals, rounded and often apiculate, greenish-brown 

 or g re y> marked in the centre with a pale glabrous escutcheon. Column with 

 short beak. 



Grassy places on the littoral. March-May. 



The var. virescens Gren. = 0. virescens Philippe has greener perianth 

 segments. It is found near Carqueiranne !, Mont Faron, Mont Coudon, and 

 the Gorge of Ollioules, but is rare. 



O. fusca Lk. (Plate XXX). The sepals greenish-yellow, the 2 petals 

 greenish-brown, rather shorter, linear obtuse, glabrous. Lip brown, velvety, with 

 2 oblong glabrous lead-coloured marks, 3-lobed, with middle lobe emarginate, 

 without appendage. Column obtuse, not beaked. 



Dry slopes and pine-woods, fairly common on the littoral and sometimes in 

 large quantities, as at the foot of Coudon. March-April. 



O. lutea Cav. The sepals yellowish-green ; the petals shorter, linear 

 obtuse, yellow. Lip rather long, reddish-brown with yellow border, and two 

 oblong glabrous pale marks near the top. Lip 3-lobed, the central one emargiri- 

 ate, no appendage. 



Hill-sides and grassy places on the littoral, less common than the last. 

 April-May. 



O. muscifera Huds. (Fly Orchis) has been seen, in the lower mountains, 

 about Breil, Tenda, and St. Martin Vesubie, but is rare. 



O. speculum Lk. The sepals yellowish-green ; the petals finely subulate, 

 much shorter, purplish-brown. Lip rather large and long, with a bluish, glabrous 



1 In Ophrys the 2 small inner perianth-segments are usually called " petals '' 

 in English books, and the outer segments merely "sepals".
