intermediates was formerly considered as evidence for uniting forms that 
would otherwise have been considered distinct, but modern research has. 
‘placed the matter ina new light. In Britain, the two species have been 
so much confused that many of the old records are quite unreliable, and 
some erroneous. 
O. incarnata, however, is less widely diffused than O. latifolia, though: 
locally abundant, as at Bransbury Marsh, Hampshire. Mansel-Pleydell 
(Fl. Dorset, p. 257) gives seven districts in Dorset for O. latifolia, and five 
for O. incarnata, but only one locality seems common to both. And he 
certainly knew and expressly mentioned the flesh-coloured form, yet in the 
first edition of his book (1874) he cited Syme, t. 1457, as O. incarnata, but 
both he and Townsend wrongly followed Reichenbach | in including 
O. foliosa, Soland., as a form of O. incarnata, for it is a Madeiran plant, 
now well known in cultivation. O. incarnata is constitutionally distinct 
from O. latifolia, for it dies out at Kew, either in ordinary soil or in.the 
rockwork bog, while O. latifolia is easily grown. It would be interesting to 
test the behaviour of O. preetermissa. RASS

OponTIopA PapiLio.—Four very diverse forms of this striking 
Odontioda were exhibited at the R.H.S. meeting held on June 2and 
last by Sir Jeremiah Colman, Bart., Gatton Park, Reigate, to whom we 
are indebted for a flower of each. The original appeared at the Temple 
Show in 1911 (0.R., xix. pp. 181, 229), but since then others have bloomed, 
illustrating once more the remarkable variation now ‘so familiar among 
secondary hybrids. The parents are Cochlioda Neetzliana x Odonto- 
glossum warnhamense (Hallii x nobile), and in the resulting seedlings the 
original yellow and white ground colours have taken the opportunity of 
again separating themselves, two being yellow and two white, all with 
copious crimson-red markings. In one of the yellows the markings take the 
form of partly confluent blotches, leaving sufficient yellow to give the 
flower a very bright appearance, but in the other the overlying red colour 1§ 
very dark and suffused, except at the tips and upper margins. The yellow 
comes out better on the lip. Both have the typical Odontioda shape, also 
one of the two white grounds, and in this the blotches on the centre of 
the petals are confluent in irregular lines, leaving elongated white areas 
between, and giving a very distinct appearance to the Hower. The fourth 
is larger, and has more of the Odontoglossum shape. In this the petals 
have a large crimson, blotch above the middle, with several smaller ones 
below, and the margins are prettily tinged with purple, a character which 
also extends to the white of the lip. In all the spiny crest is bright yellow. 
Three of the plants bore two fine spikes, and they formed a very charming 
little group.
