The first notice I find of this fine variety is in the Gardeners’ Chronicle for May Ist, 1886. On April 27th of that year it was exhibited at a meeting 
of the Royal Horticultural Society both by the Compagnie Continentale d’Horticulture of Brussels, and by R. B. White, Esq., of Earlsfield, Surrey, each 
exhibitor being awarded a first-class certificate. The following week, in the same journal, M. L. Masereel gave the history of the plant. It is said to have 
flowered out of a batch of C. Lawrenceanum which was imported through Mr. Low, of Clapton. A plant appears to have passed into the hands of Messrs. 
Linden, of Brussels, and thence into those of M. Jules Hye, of Ghent, after whom it was named. Whether Mr. White’s plant was from the same source does 
not appear to be known, A little later Prof. Reichenbach stated that a single plant appeared among a mass of the typical C. Lawrenceanum in M. Linden’s 
establishment, and that he considered it to be an albino of this species. Such is my opinion ; it appears to be a variety in which the purple has disappeared, 
probably under the same conditions as albinos, or pure white varieties of other species, are produced. The green has proved persistent, as indeed it often does 
in other albinos. It is a striking and very distinct variety, and forms a very pleasing contrast with the typical form of the species. R.A, Rolfe.

CyprirpepiuM LAWRENCEANUM was first discovered in 1878, in North Borneo, by Mr. F. W. Burbidge, who found it 
growing among small palms by the side of the river Lawas, on limestone rocks, in an atmosphere hot and humid all the 
year round, owing to its proximity to the sea; in this locality our collector, Mr. Ericsson, also found it. In its native 
wilds this plant rests but very little, and chiefly in the rainy or winter season. It starts into active growth early in the 
spring, when the young leaves are not so subject to damp off on account of the rains being less heavy. This fact 
teaches us that previous to the resting or flowering period, we ought to keep it as moist in our houses as we do during 
the time it is in growth. The plants should not be syringed overhead, but sufficient humidity should be maintained 
in the atmosphere of the house, otherwise yellow thrips attack it and soon destroy the delicate tissues of the leaves, and 
impoverish the plant. 
Many magnificent forms have flowered among the tens of thousands of plants that have reached this country 
during the last twelve years; and, indeed, this Cypripedium is one of the most stately of the whole genus. Its great, 
broad, conspicuous dorsal sepal is flamed and striped with deep purple, margined with white and rose, and in the very 
finest forms in a truly brilliant manner. One remarkable and lovely exception in colouring, entirely differing from the 
type, is the variety Hyeanum (here figured), named in compliment to M. Jules Hye, of Ghent. This remarkable and 
most handsome of all the forms of C. Lawrenceanum may be briefly described as a green and white variety of the species 
—by some writers it has been called an “albino,” probably from the fact of the conspicuous purple colouring usual, and 
nearly always constant, in all the other forms, having entirely disappeared in the var. Hyeanum. Most lovers of this 
useful and free-flowering genus regard this variation from the type as the most superb product of colouring to be found 
in the whole family; the pea-green lines of the upper dorsal sepal traversing the purest white ground, the yellowish 
green and deep green veins of the petals, and the bright and rich green reticulating of the pouch, all combine to 
produce a grand effect. 
Baron Schroder, of The Dell, Egham, exhibited at the last Temple Show of the R.H.S. the variety represented in 
our plate, when, it is needless to say, it was very much admired, and a glimpse of the beauty was eagerly sought for. 
What infinite pleasure is bestowed upon the great mass of gardeners by the exhibits from our rich and great collections 
—if only made public once in the year! and all honour is due to those who prepare these royal feasts of flowers.
