34 THE ORCHID REVIEW. 
A BRITISH HYBRID ORCHID. 
Natural hybrids among Orchids are not only very numerous, but very 
widely diffused. A most interesting British example is described and 
figured by Mr. Rolfe in a recent number of the Annals of Botany (vol. vie pe 
325, t. 18). It is a generic cross, between Orchis maculata and Habenaria 
viridis, which was sent to Kew for determination by C, H. S. Perceval, Esq. 
of Longwitton Hall, Morpeth, in July, r891. It was found in a field at 
Longwitton, Northumberland, growing with the two species just named, 
together with Orchis incarnata, Habenaria chlorantha, H. bifolia, and 
Listera ovata. It possesses unmistakable evidence of a combination od 
characters of the two parent species, as is evident from the plate, and the 
author states that the same holds good as to colour. Instead of the pale 
lilac of the Orchis parent there was a strong suffusion of green derived from 
the Habenaria, which served to modify the former colour. The flower of 
the hybrid bears a considerable resemblance to that of Orchis maculata | 
especially in the spreading sepals and the shape of the lip, yet the latter 
organ has the narrower more acute side lobes, and very small mid lobe, 
which strongly indicate the influence of the other parent. The spur ‘is 
precisely intermediate in character, having neither the long, narrow, ant 
tapering form of the Orchis, nor the short, saccate form of the Habenaria, 
but is a linear-oblong, slightly clavate body, barely over a line in length. 
The author follows the Candollean rule of compounding a name from that" 
of the two parent species, and has named the hybrid Habenari-orchis x vitid- 
maculata. The only other British hybrid Orchid known is Orchis latifoli” 
maculata, which has been recorded from Hampshire and from Plymouth. 
ODONTOGLOSSUM LUTEOPURPUREUM COBBIANUM. 
The varieties of Odontoglossum luteopurpureum, like those of O. crispu®: 
seem almost endless. The one to which the above name has been given i 
a strikingly handsome form, which has just flowered in the collection of 
Walter Cobb, Esq., Silverdale, Sydenham, Kent. The sepals are wholly 
deep chestnut, except a minute yellow tip, and a small area at the extreme 
base. The petals are of a similar Shade, with the tips and marginal teeth 
deep yellow. From middle to base extends a broad greenish-yellow 4 10, : 
and along the centre of this a narrower chestnut-brown band, which imparts 
to the variety a very distinctive appearance. The lip is rather broad at the 
apex, but otherwise normal in character. It is one of the darkest forms ¥ 
nae “ine ge aE OH ne 
have seen.
