Haxirats.—(A) Eastern. bay, Mentone, where I found one plant, 
April 10, 1866. (B) Gathered near Ventimiglia by my father, April 
5, 1866. (C) Gathered by me at Mentone, April 15, 1866. (D) Ori- 
ginally from Toulon, now cultivated at Antibes by M. Thuret, to whose 
kindness I am indebted for this specimen, the only living one I have 
ever seen. 
Remarxs.—Ophrys speculum, Link, is a very remarkable species, 
both on account of the structure of the stigmatic chamber and of the 
colour of the lip. I have never been able to find more than one plant, 
and this is the only recorded case of its discovery along the Riviera or 
in France. Parlatore (1. ¢.) says that it grows in Sicily (Palermo, etc.), 
Calabria, Sardinia, Algeria, Portugal, Spain, Greece, Rhodes, and 
Smyrna. Ophrys bombylifera, Link, has a very curious enlargement 
of the stigmatic cavity, so arranged that there is an entrance for in- 
sects exactly opposite to the anther, the pollen of which they are wanted 
to remove. This pretty little plant has been found at Mentone, in the 
Gorbio valley, by the Rev. W. Hawker; it grows also at Ventimiglia, 
La Brague, near Antibes, and at Toulon. Ophrys insectifera, var. Ber- 
tolonii, is a well-marked form, and easily distinguishable in the great 
majority of instances. Yet it is closely linked on by intermediates to 
the forms of var. aranifera, with pink sepals and purplish lips, so much 
so that many botanists take these intermediates for the types of what 
they consider a species. The var. Philippi is a very remarkable form, 
but I am assured by excellent observers that it is united by a multitude 
of intermediates to the var. arachnites (O. arachnites, Reich.). I have 
only seen one living specimen, and this I owe to the great kindness of 
of M. Thuret. I have diligently searched for var. Philippi, but I believe 
that it is only to be found in the neighbourhood of Toulon.
