THE peculiar growth of this Cattleya and the splendour of its flowers render it one of the most remarkable plants in the 
Orchid family.» The colour is quite unique among Cattleyas; the flowers look as if they were moulded out of golden 
wax, beautifully harmonising with the silvery foliage, and are perfumed with a delightful citron-like fragrance. It is not 
surprising that since it was first introduced, some sixty years ago, it has been such a favourite garden plant, and has 
become one of the most popular Orchids at the present day. It is a native of Mexico, where it is widely distributed 
in the mountainous regions. It is found on the west coast in the State of Oaxaca, and on the east coast in the State of 
Vera Cruz, at altitudes ranging from 6000 feet to 7000 feet, and is generally found on the trunks and branches of oak 
trees, and invariably growing downwards. This peculiarity of growth is continued when the plants are under cultivation, 
for no matter in what position they are placed, their growths always turn towards the earth. In the neighbourhood of 
Oaxaca this Orchid flowers during March and April, and the beauty and fragrance of its flowers are highly esteemed by 
the native Mexicans. 
Fortunately, Cattleya citrina has been and still is imported in large quantites, otherwise it would soon become 
Scarce, on account of its being one of those plants requiring more than ordinary skill in order to maintain it in continuous 
health and vigour. Thousands of imported plants have been sacrificed because cultivators do not heed the conditions 
under which this Cattleya can alone be successfully grown and flowered. There are three essential points to observe in its 
culture: firstly, the proper season to procure imported plants ; secondly, the correct period and duration of its resting 
season ; and thirdly, the season for starting the plants into active growth. Imported plants should be purchased only 
from the importations sold during December and January, as at that season the plants are entirely at rest. After freeing 
the bulbs of such superfluous matter as dead roots, stems, and such like, the masses should be secured on blocks with 
copper wire and tacks, with the bulbs pointing downwards. Hard wood such as teak, apple, or hawthorn is preferable 
for the blocks. Some prefer to grow it on flat trellises or rafts, but in no case is compost of any sort needed around 
the bulbs. The plants should be hung against a wall in a temperature of from 55 deg. to 60 deg., and in a position 
where they would derive all available sunlight. Under this treatment the bulbs will soon push out new roots and 
commence to form new growths, when the temperature should be raised and the plants syringed copiously three or four 
times a day, the house being at the same time ventilated ; the temperature may rise as high as 80 deg. F., and this 
treatment should be continued until the bulbs are fully developed. When the bulbs have attained their fullest size, the 
resting period commences, and this extends during at least six months, and the longer the period the better. During 
rest the plants must be placed so as to be fully exposed to direct sunlight in an airy house or corridor, and water must be 
given only in sufficient quantity to prevent the bulbs from shrivelling. The temperature may fall as low as 50 deg. F. at 
night during the winter, and about January or February the plants should be again removed to the growing house. The 
flowering season in this country occurs at no stated period, but is usually between May and August.
