82 THE ORCHID REVIEW. 
many such have appeared during recent years, and have received distinctive 
names. It is not often, however, that one has an opportunity of comparing 
them together, and we are therefore the more pleased to be able to 
illustrate a remarkable group which was exhibited by Mr. J. E. Rothwell, 
of Brookline, Mass., in the Horticultural Hall, Boston, on January 6th last, 
and to which the Silver Medal of the Massachusetts Horticultural Society 
was awarded. The features of the group have been permanently fixed by 
the unerring eye of the camera, and we are now able to reproduce the 
picture. Beginning on the left we have first an example of P. i. Ernesti 
(fig. 10), bearing three flowers. Next comes P. i. Laura Kimball (fig. 11), 
with a single flower, and this is evidently very near to the well-known P.i. 
Sandere (fig. 12), of which a fine example with three blooms occupies the 
centre of the group. Below it on the right is P. i. Sanderianum (fig. 13), 
with a single flower, clearly distinct in shape. Then comes P. i. Young- 
ianum (fig. 14), and lastly, on the extreme right P. i. William Millie Dow 
ae 15). The last named is a fine thing, and, like the preceding one a8 
P. i. Ernesti, has more distinct traces of spotting than the others. Tt# 2 
cea) a most beautiful group, and its equal has not previously be 
exhibited elsewhere. 
Mr. Rothwell writes that he takes great interest in Cypripediums, of 
which his collection contains over 350 varieties. He has many houses of 
seedlings, and during last year a number from bellatulum album made their 
appearance and are doing well. His crosses are mostly from bellatulum, 
concolor, niveum, and Rothschildianum, and the seedlings make rapid» 
growth, doubtless owing to the large percentage of clear, sunny days. We 
hope that they will prove equally satisfactory when reaching the flowering 
stage, and perhaps we may have the pleasure of seeing some of them 
hereafter. 
CALENDAR OF OPERATIONS FOR MARCH. 
By H. A. BURBERRY, Orchid Specialist, King’s Heath, Birmingham. 
TEMPERATURES.—There should now be a slight rise all round above the 
figures given for January last, even without sun heat; and when the sun 
shines, the rise will, of course, be considerable, which will do a great deal © 
of good. 
ATMOSPHERE.—Moisture should now be distributed rather abundantly. 
The fire heat by night, and the increased sun power by day, will cause the 
moisture to evaporate quickly, and twice a day should not now be too 
much. In any case it must be once daily, and that when the temperature 
has risen in the morning. 
WarTERING.—This should still be performed with due care and
