SEPTEMBER, 1903. ] THE ORCHID REVIEW. 285 
darker flowers than the typical form, with a more obtuse lip, and was 
dedicated to T. Statter, Esq., as a variety of D. Phalznopsis. Other plants 
have subsequently appeared, possessing the same essential features. I had 
previously noticed a resemblance to D. bigibbum, and a comparison of the 
three torms mentioned suggests the probability that the so-called variety 
is a natural hybrid between the other two, just as D. xX Leeanum, which 
also comes in importations of D. Phalznopsis, is a natural hybrid between 
that species and D. superbiens. The persistently smaller flowers, more 
recurved petals, and darker colour, all show a strong approach to D. 
bigibbum, though the elliptical patch of whitish hairs on the centre of the 
lip of the latter is not distinctly traceable. But the flower of the so-called 
variety is so generally intermediate between the two species mentioned that 
I think it must be a natural hybrid between them. It would be interesting 
to have further evidence on the subject, and to see the result of hybridising 
the two species together.

RARE ORCHIDS AT KEW. 
SEVERAL very interesting rarities are now flowering at Kew. Dipodium 
pictum is producing another spike in one of the warm houses, where also. 
may be seen a fine plant of the remarkable Bulbophyllum granditlorum 
bearing seven flowers, the rare B. mandibulare, the curious little B. 
saltatorium, with a feathery lip, like a miniature B. barbigerum, the striking 
Trias disciflora, Saccolabium penangianum, and Liparis disticha, the red 
flowers of the latter being rather unusual in the genus. Phalznopsis. 
Esmeralda is represented by five flowering plants ; and a pan of Habenaria 
carnea, containing several plants, is very effective. Among plants which 
cannot be called rare may be mentioned Paphiopedilum Charlesworthii, P. 
Spicerianum, P.x Maynardii, Phragmopedilum x Sedeni, and P. X calurum,. 
all of which are flowering freely and are very effective. 
In the Cool House is a good pan of the chaste Stenoglottis longifolia 
alba, bearing several spikes, and a mass of the typical form, which is a 
really effective autumn-flowering Orchid, being easily grown, and one can 
always rely upon its flowering freely at this season. A plant of Epidendrum 
vitellinum with five racemes of its brilliant flowers is also very effective,. 
other interesting things being a good plant of Odontoglossum aspirrhinum 
with six spikes, Oncidium exasperatum, lonopsis paniculata, several inter- 
esting Masdevallias, and the rare Restrepia trichoglossa. 
In another warm house Neobenthamia gracilis is carrying four racemes. 
of flowers, other interesting things being Dendrobium Aphrodite, a pale form.
