where so many species are found in so small a space, except on some of the 
moist prairies of Lavaux-St.-Anne, Luxembourg. Several of them have a 
liking for chalky soil, but this may be only a coincidence, for scarcely a 
tenth of the whole is calcareous. Lastly, it is remarked that all the 
Orchids were found on the disturbed part of the ground, to the exclusion of 
the parts where the soil remains undisturbed. All the species enumerated 
were found in flower, and must have been there some time before being 
noticed, which shows that the conditions were favourable. Other old 
quarries in the neighbourhood were explored, but without finding a single 
Orchid. In the author’s garden, situated at Ermitage, less than two miles 
away, only two specimens of Orchids are known, namely, Orchis latifolia 
and Listera ovata, and numbers of European Orchids which have been 
introduced at different times have disappeared in a few years. 
In conclusion the author asks, Were the seeds introduced with the 
roots of the trees planted, or were they carried by birds or other animals, 
or by the wind? The presence of trees seems to be correlated with the 
appearance of the Orchids, but if the latter were introduced adhering to the 
tree roots a more general dispersal would be expected. On the other hand 
it is difficult to believe that the wind could carry the seeds to such 
distances, for the latter are shed from July to September, when the high 
winds are accompanied by rain. What is the agent and the method of 
dispersal ?

BRAZILIAN ORCHIDS. 
AN interesting account of the Orchids of the State of Pernambuco, Brazil, 
by Consul George A. Chamberlain, of Pernambuco City, appears in an 
issue of the Consular Trade Report. 
‘“The State of Pernambuco produces a large variety of Orchids, 
principal among which are Cattleyas labiata, Leopoldi, guttata, and 
granulosa. Besides these Cattleyas, other species well represented are 
Burlingtonia fragrans, Oncidium divaricatum, Onciditm Gravesianum, and 
Miltonia spectabilis Moreliana. Almost all of these are spectacular, and 
some of them remarkably beautiful, but in trade only the Cattleyas 
have any importance, and of these, in turn, the labiatas are the most profuse 
and give the greatest return. They are the large-lipped, flaring flowers of 
every shade of mauve and pink, centred with magenta and yellow, that 
have become, during the last few years, a frequent feature of floral 
decoration at home. They grow generally three, four, and five blooms on 
a stalk, and their delicious fragrance greatly resembles the odour of Lilacs. 
‘* Of Cattleya labiata, Pernambuco exported about 15,000 plants of eight 
leaves and upward during the season ending with April, 1909. The plants 
are gathered at three central points—Caruaru, Garanhuna, and Timbauba.
