NovEMBER, 1907-] THE ORCHID REVIEW. 335 
fortunate enough to live out of the reach of the extremely detrimental 
town fogs, can hardly realize how much we have to be thankful for. From 
time to time fogs do occur in country districts, dense enough to ruin buds 
and flowers, but this is the exception rather than the rule. In most cases 
if the interiors are kept as dry as possible, reducing the bottom air to a 
minimum, and likewise reducing the pipe heat, and refraining from watering 
till the fog lifts, little harm will accrue. I prefer leaving a crack of air on 
the bottom ventilator to shutting them entirely. The one point to be most 
closely followed is to see that the pipe heat is kept well in hand. In the 
vicinity of towns where much smoke is in the atmosphere, when a fog is 
seen coming on every precaution should at once be taken to prevent the fog 
from entering the houses more than possible, by closing all ventilators, 
and not opening any outside doors more than is absolutely necessary. No 
watering should be done, and all floors and staging should be kept quite dry. 
With the interiors well dry, the plants can be better treated, as they will 
not hurt so much when deprived of all fresh air. It will also be very 
necessary to keep the heating arrangements well in hand, especially after 
the houses and plants have become fairly dry. 
CATTLEYA LABIATA. 
Tue beautiful Cattleya labiata will shortly be in flower again, and it may 
be interesting to reproduce some important information respecting its 
habitat, given in an article by M. Louis Forget, entitled ‘‘ Erreurs 
géographiques concernant les Orchidées,”” which appeared in 1897 (Le Jard. 
1897, pp. 246—248), and which I had overlooked until recently. It has an 
important bearing on the existing records, which I have already summarised 
(O.R. i. pp. 329—332 ; viii. pp. 362—365). Alluding to the absence of a clue 
to its exact habitat, M. Forget remarks that it is fair to suppose that 
Swainson explored the provinces of the north of Brazil, because this plant 
was never indigenous in the province of Rio de Janeiro, and still less of the 
Organ Mountains, which have been quite wrongly indicated as its habitat. 
As to the plamt which Gardner found on the Gavea, near Rio, in 1836, he 
says that it is much more probable that Gardner mistook for Cattleya 
jabiata—which alone was known and described at this period—the Lelia 
lobata, which still exists in this locality in numerous examples. Gardner’s 
dried specimens, fortunately, still exist, though the flowers are not well 
Preserved. On soaking one out and examining it in detail I find that 
M. Forget’s suggestion is right, for the segments, though not perfect, match 
those of the Lelia, and not of the Cattleya. The pollinia are not present. 
This gets rid of the whole of the argument based upon Gardner’s record 
and specimens, so far as this particular locality is concerned. 
Gardner also recorded finding Cattleya labiata at Sapucaya, oa the
