220 THE ORCHID REVIEW. (JULY, 1908. 
plant of Lycaste Deppei, the rare L. Dyeriana, with the habit of Cattleya 
citrina and light green flowers, Cymbidium Lowianum, Disa x Veitchii 
and X langleyensis, Lissochilus Krebsii, species of Pleurothallis, Physo- 
siphon Loddigesii, Theodorea gomezoides, Stelis omalosantha, Masdevallia 
muscosa, calura, Carderi, a well-bloomed plant of M. Rolfeana, and 
numerous others. 
In the adjacent Warm house is a good plant of the striking Bulbo- 
phyllum virescens, with the feathery-lipped B. barbigerum, some good 
Paphiopedulum Curtisii, ciliolare, glaucophyllum, Victoria-Mariz, nigritum, 
Aérides odoratum, A. falcatum var. Leoniz, Vanda tricolor and suavis, &c. 
In the Rockery outside is a fine clump of the North American Epipactis 
gigantea, with over forty spikes of flowers, which are brownish-green, 
striped with red on the basal] half of the lip, and with a zone of orange on 
the front lobe. A fine clump of Orchis foliosa is flowering in the bog near 
the dripping well, and not far away are some plants of Listera ovata, while 
a fine dark form of Orchis latifolia, with green leaves, is just passing out of 
bloom, also a very fine clump of Orchis latifolia x maculata, with hand- 
somely spotted leaves, and about twenty spikes of flowers. 
ODONTOGLOSSUM CRISPUM.—The question is again asked whether the 
so-called blotched forms of Odontoglossum crispum are varieties of that 
species or hybrids of complex parentage. It has long been believed that 
some at least of them belong to the latter class, but it is very difficult to 
say where variation proper stops and hybridisation begins, especially in 
view of what is now known about reversion. Experimental evidence is 
wanted on the question. In view of the known facts of reversion it would 
be well worth while to carefully self-fertilise some well-known heavily 
blotched variety, and thus raise a batch of self-fertilised seedlings, to see 
how far the variety keeps constant, and how far it reverts to earlier forms. 
The experiment would be well worth making from a purely horticultural 
standpoint, for it would be just as likely to produce forms of merit as woul 
the crossing of blotched forms with each other, besides throwing an 
important light on an interesting horticultural question. Which of our 
hybridists will immortalise himself by making the experiment ? Another 
experiment which would be well worth making would be to fertilise some 
good typical unspotted form of O. crispum with a good O. x Wilckeanum 
ef known origin, one of the fine forms which have been raised artificially 
between O. crispum and O. luteopurpureum, carefully noting the result as 
the seedlings flowered. This also would be well worth doing froma purely 
horticultural standpoint, for it should produce some spotted forms of good 
quality, whether they matched wild forms or not. Some of our hybridists 
should take the hint.
