82 THE ORCHID REVIEW. 
from materials supplied by Mr. Day (Flora, lv., p. 278). From this self- 
same original plant it was also figured in the Gardeners’ Chronicle (1875, iil, 
pp. 277, 278, fig. 54) and in the Floral Magazine (1875, t. 191). It was 
re-imported by Messrs. James Veitch and Sons, in 1879-80, through their 
collecter, Curtis, who found it growing on the margins of lakes and swamps 
in partially exposed places in north-east Madagascar, and later by other 
firms, so that it is now more frequently met with in collections than 
formerly. The leaves sometimes reach as much as ten inches long, and the 
arching racemes as much as two feet, and bear from eighteen to twenty-four 
flowers, which are pure white and very fragrant, the spur being about six 
inches long and light cinnamon in colour. The shape of the flowers is well 
shown in the illustration. It succeeds well in the East Indian house treated 
like Aérides and Vandas, and with proper care will thrive for years. It is 
occasionally confused with A. articulatum, Rchb. f., which probably arose 
from an importation of the latter having been sold for it in 1881. A. 
articulatum, which also was introduced by the Rey. W. Ellis, is a smaller 
plant with shorter leaves and smaller flowers. 
HYBRIDISING DENDROBIUM WARDIANUM. 
DENDROBIUM Wardianum appears to be abad seed-bearer. Mr. Isaac Cart, 
of Twerton-on-Avon, writes:—‘‘Is there any secret in successfully fertilising 
Dendrobium Wardianum? For the last two years I have placed pollen 
on numberless flowers of this Dendrobe. I have tried various times of day, 
and various atmospheric conditions. I have used pollen of varying freshness, 
on flowers in varying stages, from the newly opened to the faded. The one 
result I have obtained is that the flower fades, but drops off in two or three 
days.” Mr. Eichel also wrote:—‘‘D. Wardianum is another bad seed- 
parent ; in fact, very difficult to fertilise. Only one cross has so far been 
recorded where D. Wardianum acted as the seed-bearer, namely D. * 
Lutwychianum” (Orch. Rev. v., p. 83). We find, however, that it is recorded 
as the seed-parent also of D. x micansand D. X murrhiniacum (in the record 
of the latter at page 227 of our first volume, the parentage is accidentally 
reversed), so that three hybrids, at least, appear to have been successfully 
raised from it as the seed-parent. We shall be glad if other correspondents 
will give us their views on this matter. In view of the difficulty, howeve!, K 
seems advisable either to use D. Wardianum as the pollen parent, OF to ma = 
the reversed cross also at the same time, which would give two chances of 
obtaining a capsule of hybrid seeds.
