172 THE ORCHID REVIEW. (JUNE, 1922. 
three inches apart on short hairy pedicels. The flowers have about the 
dimensions, but not the fleshiness, of those of A. Cathcartii. They are 
aichly coloured with crimson red-brown on a yellow ground, the lip 
resembling that organ in A. moschifera and in A. annamensis, rather than 
in A. Cathcartii, while it exhibits more yellow than in'the sepals and petals. 
In appearance the flowers are different from the smaller kinds. The curious 
curves so characteristic of A. moschifera and A. annamensis are absent, the 
waved segments being more or less flat and nearly equal. Most remarkable 
are the two basal flowers, which, separated from the remainder by a longer 
interval, are bright yellow, dotted irregularly and sparsely with brown. In 
them the segments are perhaps more fleshy than in the remaining flowers, 
and they are broader and blunter, but there appears no decided difference 
in their structure, and the operating cause of their colour is not yet known. 
Though reaching such large dimensions, the plants flower in a 
comparatively dwarf state. During the last summer two plants in Messrs. 
Sanders’ nursery little more than two feet high each produced a spike. 
Naturally, such spikes are not as long as those produced from the huge 
specimen, for instance, in the collection of the Rev. J. C. B. Fletcher, at 
Mundham Vicarage, Chicester, which has carried 23 spikes of full length— 
a curtain of flowers, or from the plant, nearly its equal, grown by Messrs. 
Sanders in their Bruges nursery in pre-war days; it survived the war, proof 
of the vitality of the species, but only as a relic. 
A. Rohaniana is very similar to A. Lowii, and in all probability is but a 
variety. As far as can be observed under cultivation, it differs in its slightly 
more moderate habit, the brighter tints of the flowers, and the fact that there 
are four yellow basal flowers instead of two. Out of flower, the two forms 
might easily be confounded, as might the flowers. Nor can the characteristics 
of the basal blooms be regarded as arbitrary. A. Lowii usually produces 
-only two, but a third and fourth have been noted, and occasionally they 
have not conformed to either, but have shown a curious colour mixture of 
the two. A. Rohaniana is said to have flowered in Europe as long ago as 
1854, hence its introduction cannot have been much later than that of 
Pee Lowit, probably it was imported as that species. The adjoining 
illustration is of a fine specimen flowering in the collection of the 
Rev. J. C. B. Fletcher. 
Comparing these two species with the preceding, wide differences, 
though more superficial perhaps than real, are at once apparent, so much 
sO as almost to entitle them to a separate genus, but the labellums show the 
connection and transition better than do the inflorescences. In the earlier
