104 THE ORCHID REVIEW. [APRIL, 1916. 
exacting. The usual routine of cleaning, the war against insect pests, and 
such small details of successful cultivation must have every attention, 
especially the environment of so-called difficult plants. Vigilance in these 
matters is half the secret of success. 
| v | WARSCEWICZELLA AMAZONICA. | y | 
ARSCEWIZCELLA amazonica is by far the finest species in the 
genus, and is, we believe, only represented in cultivation by the 
unique plant in the collection of Elizabeth Lady Lawrence, at Burford 
(gr. Mr. E. Swinden), which has just bloomed again. The flowers are very 
large, the lip having an expanse of two inches, and the colour is white, with 
slight radiating purple lines on the disc. _ It was originally discovered in 
May, 1853, by Warscewicz, when collecting in the Upper Amazon district, 
and was described by Reichenbach in the following year (Bonplandia, 1854, 
p- 97) from an original coloured drawing, which was all that was 
known to him. The author described it as having flowers twice as large as 
in W. discolor, snow white, with long purple lines on the disc of the lip. 
He afterwards found a fine dried flower in the Lindley Herbarium, where 
it is still preserved. A figure was also published (Xen. Orch., 1. p. 222. t- 
99, fig. 2), with the information that it was sold by auction in London as 
“Probably a new Huntleya. Dead or doubtful. Still has life in it ” (this 
presumably from Warscewicz’s Sale Catalogue). Reichenbach afterwards 
reduced Warscewiczella to a section of Zygopetalum, and the plant became 
Zygopetalum amazonicum (Rchb. f. in Walp. Ann, vi. p. 655). Its 
appearance in cultivation, nearly forty years later, was quite unexpected ; 
in fact, its identity was then unknown. On June 7th, 1892, a very 
beautiful Warscewiczella was exhibited at a meeting of the R.H.S. by 
Messrs. Linden, Brussels, under the name of W. Lindeni, and was awarded 
a First-class Certificate. It then passed into the collection of Sir Trevor 
Lawrence, Bart., at Burford, and was subsequently figured in Lindema 
(vili. t. 337) under the name of Zygopetalum (Warscewiczella) Lindeni, 
Rolfe, Reichenbach’s arrangement having been adopted by Bentham in the 
Genera Plantaram. Nothing was stated about the origin of the plant; but 
somewhat later flowers were sent by Mr. E. S. Rand, of Para, who had 
obtained the plant in the Upper Amazon district, and the information led 
to its identification with the earlier but imperfectly known plant of 
Warscewicz, and its history was given (O.R., ii. p. 304). It is strange that 
so beautiful a species should still be so imperfectly known, and, apparently , 
so difficult to propagate. R.
