206 MR. C. B. CLARKE ON A HAMPSHIRE ORCHIS 
In trying to escape, it naturally goes up an incline over the valve, 
and so reaches the fertile anther-cells, when it gets covered with 
pollen, and presently escapes by pushing open the upper lip, 
which is folded over itself so as to form a chamber. The special 
conformation of this species seems to demand explanation ; and as 
an important end could be attained in the way I have suggested, 
I venture to submit that it may be the right explanation. This 
species seems adapted for small insects which could never be 
touched with pollen in the usual way; but being forced to pass 
through the anther-chamber, if I may so term it, they get well 
dusted.

Tre Orchis is plentiful in the marshes of the River Test, and is 
allied to O. latifolia, Linn. 
O. latifolia, Linn., is abundant in the same marshes: it is 
figured in Sowerby ; and the same plate is repeated by Syme, the 
name being altered to O. incarnata; but it does not represent 
O. incarnata, Linn. O. latifolia, Linn., is well depicted in 
Sowerby’s plate: the leaves area heavy green, not rarely spotted ; 
the spike is somewhat lax, often broader at the base; many of 
the bracts are longer than the flowers; the flowers are reddish 
purple, varying thence to white; there is no yellow. The North- 
British form of O. latifolia sometimes contains some yellow. 
The Hampshire Orchis (Plate XXXI.) has pale green leaves 
never spotted ; the spike is cylindric, dense with strict flowers; 
few of the bracts are longer than the flowers; the flowers are a 
pale flesh-colour with yellowish lip, fading to a sallow yellow ; 
the margin of the lip has a line sometimes bright rose when 
young ; but the flowers have at no period any purple about them. 
This Orchid I described in my ‘ List of Andover Plants,’ pub- 
lished in 1866, as O. incarnata, Linn., var. I have lately looked 
through the Herbaria of Lindley, Borrer, and Watson without
