120 THE ORCHID REVIEW [May, 1916. 
whether the difference in size is a constant character must remain until 
further materials come to hand. There are several imperfectly-known 
species of this racemose section of the genus. R.A.R.

HE remarks of Mr. Thomas Knight at page 61 of your February issue, 
anent the Cattleya described by me at page 30, call for a few other 
explanations, which I hasten to make. There is not the slightest doubt 
that the flower I referred to is of the labiata species, neither can there be 
any doubt about all the Orchid plants I obtained from Ceara being of the 
same family. On my way back from Rio, last month, I had occasion to 
see in Bahia some plants of the labiata group imported by a friend of mine 
from one of the leading Orchid dealers in England, and invoiced as C. 
Gaskelliana, from Venezuela. These, as well as some imported by my said 
friend from Ceara, had just burst into full bloom, and we were both 
astonished and agreeably surprised to note, on minute investigation, that 
both plants and flowers were absolutely alike. 
C. labiata is to be found in all the hills in the rainy belt region of 
Pernambuco, Parahyba and Ceara, the last place, where they cease, being 
the Serra de Maranguape. Travelling eastward labiata can be found in 
almost every spot where moisture abounds, but coming westward from 
Ceara no Cattleyas are found again until at least 500 miles from the mouth 
of the Amazons. Here C. superba is found on many of the rivers, and C. 
Eldorado only on the Rio Negro and its neighbourhood. C. Harrisoniana 
is only to be found in the warmer portions of the hills around the Italiaya 
and Sao Paulo ranges and a portion of Minas Geraes and Rio Janeiro. 
Their pseudobulbs are taller—twice as tall as the tallest pseudobulbs of C. 
superba which comes from the Rio Madeira, and are considered the biggest 
of the genus. 
You have already shown the dapcsabaliy of a natural crossing between 
plants found so many thousand miles apart, and I will not dwell on that 
point. 
I hope this particular plant will flower again, and I shall take the liberty 
of sending you another dried flower and a photograph so that this doubtful 
Cattleya may be finally classified. J. Stmao DA COosTA.

[Besides not growing together, C. labiata and C. Gaskelliana do not 
bloom quite at the same, period, but we hope that further materials will 
suffice to clear the matter up.—Eb.]|
