316 THE ORCHID REVIEW. [OcroBer, 1909 
crimson on a lilac ground. The isthmus is similar in colour, and rather 
shorter than in many of the granulosa hybrids. 
CATTLEYA X IRIDESCENS.—A striking Cattleya, of which a group of 
seven plants was exhibited by Messrs. Stanley & Co. at the R.H.S. meeting 
held on April 14th last. It issaid to have been raised from C. bicolor ? and 
C. Eldorado g, and is comparable with C. x Iris in general character. 
It is most like C. bicolor in shape, but larger, and the petals about twice as © 
broad, while the lip is much dilated and distinctly crenulate or denticulate 
in front, with infolded side lobes about half as long as the column, and a 
long, deep yellow isthmus. The colour is surprisingly variable, for in three 
of the seedlings the sepals and petals were deep yellow, in two others 
distinctly purple, while in the remaining two they were orange-buff, with a 
suffusion of salmon colour. The front lobe of the lip is bright purple, in 
some cases with a whitish margin, in others wholly violet-purple. Four of 
the forms have been sent by Messrs. Stanley, but we saw the others. It is 
a very beautiful and variable hybrid, and Messrs. Stanley are confident that 
the parentage has been correctly recorded. The variety splendens had light 
yellow sepals and petals, with a suffusion of rose, and the front lobe of the 
lip was marbled with purple on a lighter ground and the margin nearly 
white. 
ANGULOA UNIFLORA AND A. EBURNEA. 
AN interesting Anguloa was exhibited at the R.H.S. meeting held on August 
31st last by Mr. H. A. Tracy, of Twickenham, which was said to have been 
imported from Peru, and the Orchid Committee suggested that it was 
probably identical with that on which Ruiz and Pavon founded the genus. 
It was described as far superior to the smaller and more angular form 
generally seen in cultivation; the flower ivory white, of wax-like substance, 
and the labellum spotted with red in the interior (Gard. Chron., 1909, ii. p. 
174). I saw the plant and suggested that it was A. eburnea, and now that 
Mr. Tracy has sent the flower to Kew the identification can be confirmed. 
It is said to have been imported from Moyombamba by Mr. Kromer, 
together with Cattleya Rex. 
Anguloa eburnea was figured in the Orchid Album in 1884 (iii. t. 133), as 
an exceedingly rare and very distinct species, which had been received from 
the collection of Sir Trevor Lawrence. It was said to be a native of 
Colombia. It appears to have been first described in 1868 (Will. Orch. Gr. 
Man., ed. 3, p. 67). The details of the lip are not shown in the figure, but 
fortunately a flower was drawn by Mr. Day in August, 1883, with full 
analytical details (Orch. Draw., xxxvii. t. 49). Mr. Day remarked: ‘ This 
is a very rare species. I once had a single plant. Mr. B. S. Williams sent 
me this flower which he received from Sir Trevor Lawrence for the Orchid
