arachnites is present, the other two are invariably to be found, 
and in bloom at the same time, O. fucifera being nearly out of 
flower and O. apifera just in perfection, and the pollen-masses on 
each still remaining fit for fertilization. 
Fourthly, Under a power of the microscope of about two 
hundred diameters, a beautifully netted case, which covers each 
seed like the calyptra of 
some Mosses, presents it- 
self. Each mesh of this re- ex 
ticulated covering is again 
beautifully and variously 2 
marked, and these mark- 1 
ings are sufficiently distinct 
in each Orchis to point out 
the species almost unerr- 
ingly. Those of O. apifera, 
O. fucifera, and O. arach- 
nites ave here figured,* in 
order to show, as a further 
proof, that the latter is a 
hybrid, the markings beg an exact intermingling of the two 
first-named species. 
N.B. I state unhesitatingly that there are not two British 
Ophryses bearing the names of O. aranifera and O. fucifera, or 
even such varieties ; but which is the correct one, I am not suffi- 
cient botanist to determine, but I am inclined to adopt that of 
O. fucifera.

In the preceding paper I have advocated the classification, in 
three subgeneric divisions, of our indigenous Mieracia, and have 
* Fig. 1 (lower figure), seed, or germ, of O. apifera. 2. Seed of O. arachnites. 
3. Seed of O. fucifera. The globular form in the centre is the true seed.—The 
upper figures represent a single mesh of each respectively, with its markings.
