Cattleya Walkeriana, Gardner 9 in the London Journal of Botany, vol. 2, p. 662 : alias C. bulbosa, 
Bot. Register, 1847, t. 42. 
-non the opportunity of figuring this beautiful flower in really fine condition we have to express our 
obligation to C. B. "Warner, Esq., in whose collection, at Hoddesdon, it has lately blossomed. 
In the Botanical Register a small specimen was published some years since, from Mr. fiucker's 
garden, under the name of Cattleya bulbosa, its identity with what the late Mr. Gardner had 
previously called Walker's Cattleya not having been suspected. Mr. Sucker's plant had, however, 
a much more richly coloured lip than this, and must have been a distinct variety. 
According to Gardner it inhabits the country beyond the diamond district of Brazil, where 
it was found by Mr. Edward "Walker, his assistant, on the stem of a tree overhanging a small stream 
which falls into the Eio San Francisco, 
The stems are club-shaped and furrowed, each having one leathery, concave, blunt leaf, which 
is by no means wider at the base than apex ; when young or ill-grown they are short and oblong, in 
which state they gave rise to the name C. bulbosa, now cancelled. The flowers grow singly, or 
in pairs, from within a short, narrow, reddish spathe, and are full five inches in diameter, fragrant, 
and bright, but not deep, rose colour. The sepals are oblong, acute, and membranous. The petals 
are broad, oblong, acute, slightly wavy, but not lobed. The lip, which is a richer rose than the 
other parts, is small, roundish at the end, and emarginate, with two narrow, erect, lateral lobes, which 
fold over the lower part only of the column. The column itself is very broad, fleshy, rounded, with 
no lobes or notches such as are found in C. pumila.
