coloured figure (Orch. Deutsch., t. 19 b.) shows some spots in the leaves, 
suggesting the secondary hybrid between O. incarnata and O. Braunit. 
Indeed the figure he calls O. latifolia, I. (t. 21), seems to represent O, 
Braunii, a hybrid between O. latifolia and O. maculata, which Barla has 
also figured as O. latifolia. O. Aschersoniana, Hausskn., was described in 
1885, but we have not been able to consult the description. Camus, how- 
ever (Monogr. Orch., p. 239), refers it here, though in an earlier paper (Journ: 
de Bot., vi. p. 418) he referred O. Aschersoniana doubtfully to O. hematodes, 
Rchb. f., which is evidently incorrect, for Camus says the leaves of this 
hybrid are unspotted, while O. hazmatodes is described as having them very 
densely spotted with black. The leaves of the West Drayton plant are 
unspotted, as also are those of both the parents. Indeed we were unable to 
find any Orchis with spotted leaves, which suggests the absence of O. 
maculata, and naturally, of its hybrids, from the locality. The West 
Drayton hybrid differs from Schultz’s figure in having narrower, unspotted 
leaves, and lighter coloured flowers, which are almost precisely intermediate 
between those of the two parents. 
The West Drayton hybrid is probably identical with the one recorded 
from Hambledon, S.Hants., by Mr. Druce, as O. incarnata X pretermissa, 
(Rep. Bot. Exch. Club, 1915, p. 212), for a specimen of the West Drayton O. 
latifolia was sent by Mr. Dymes to Mr. Druce and was identified by the 
latter as O. praetermissa, which has now been recorded from many localities. 
And we believe that the same hybrid occurs in the Hern Meadows, 
Hampshire, where Townsend remarks (J‘/. Hampsh., p. 595) that “the 
purple-flowered form grows intermingled with the flesh coloured form and 
there seems to be no difference between the two in the time of flowering,” 
while O. latifolia, which also occurs there, blooms later. In the absence of 
specimens, it is difficult to identify this so called purple incarnata, and we 
had taken it for O. pratermissa (O.R., xxiii. p- 207), this view being strength- 
ened by the record that the pink incarnata and the later-blooming O. 
latifolia are found with it. The name O. pretermissa had not then appeared, 
and the possible source of confusion will be seen presently. This hybrid 
doubtless occurs elsewhere, and Scully in his Flora of Kerry remarks (p. 279) 
that when O. latifolia and O. incarnata grow together, ‘‘as they sometimes 
do abundantly, intermediate forms have been gathered which could not be 
definitely referred to either species. | Mr. Marshall, who noticed similar 
forms about Castlegregory, &c., has suggested a hybrid origin for the 
plants.”’ oe 
A similar remark to that made by Mr. Scully applies also to O. latifolia 
and O. maculata, for a most perplexing set of intermediates (known as O. 
Braunii), occurs where these grow intermixed, and now we have evidence 
of the occurrence of the third combination in Britain, namely O. incarnata
