CATTLEYA TRIANZ. 
Tuis handsome and popular Cattleya is now making a fine show, and a 
short account of it and its numerous varieties will therefore be specially 
appropriate at this season. 
-It is said to have been originally discovered by M. J. Linden, in 1842, 
near Fusagasuga, in the province of Cundinamarca, in New. Granada, 
though it was not until many years afterwards that his collector, M. Braam, 
sent living plants to Europe. In 1855 plants were offered for sale for the 
first time, but it was not described until 1860. It was, however, the late 
Mr. Rucker, of Wandsworth, who first introduced the plant into cultivation. 
As long ago as 1848 a plant was sent to him by a correspondent in:New 
Granada, which had been gathered in the valley of the Upper Magdalena 
River, which flowered in the following February. Dr. Lindley, to whom 
two flowers were sent, then gave it the name of C. quadricolor. Shortly 
afterwards it was mentioned in Paxton’s Flower Garden (vol. i. p. 6), but 
unfortunately no description appeared until 1864, when it had been succes- 
sively described as C. Trianz and C. Rollissonii. 
The species is spread over a large area in New Granada, between the 
second and fifth parallels of north latitude, and occurs on all three Cor- 
dilleras. It is very abundant in the Magdalena basin and certain other 
localities, and different collectors who have been in search .of the plant 
speak of its great beauty when seen in immense masses in its native home. 
They also report the extreme variability of its flowers as regards their 
coloration, a statement fully confirmed by the numerous plants now culti- 
vated in Europe. 
It is this extreme anabelity that constitutes one ae its preutent chased 
and its habit of flowering during the winter months gives it great value as 
a garden plant. A multitude of forms have received distinctive varietal 
names, and were it desirable it would be possible to extend the number 
ad infinitum. Many of these forms, however, represent individuals rather 
than varieties in the true sense, though some of them present a constancy 
of character throughout a series of plants, which, however, in some cases 
probably arises from the subdivision of one original piece. 
The typical form, or what may be considered as such, has the sepals and 
petals delicate rosy mauve, the side lobes of the lip somewhat similar, the 
front lobe bright purple-crimson,.and the. disc orange-yellow. The variety 
virginalis has pure white flowers, with the disc of the lip pale yellow, and 
much reduced in size. It is the purest white form known. The variety. 
alba differs in having the disc of the usual size and a small rosy-lilac blotch 
in front of the same. This and the preceding variety are sometimes con- 
founded together. Dodgsoni has also pure white sepals and petals, the 
front lobe of the lip magenta-purple bordered with lilac, the side lobes pale
