142 THE ORCHID REVIEW, 
the very fine variety concinnum, in which the petals are over three-quarters 
of an inch across, and the lip nearly as broad. 
‘Enclosed with the preceding are a fine form of O. crispum with very 
broad rosy sepals and white petals and lip, the latter bearing a few small 
chestnut spots; two of O. X Wilckeanum, one very large with yellow 
ground and large dark spots, the other with a whiter ground and more like 
O. luteopurpureum in shape; and two handsome forms of O. triumphans, 
one of which has the dark front of the lip broadly margined with white, the 
margin being a line broad. 
Lastly must be mentioned a remarkable inflorescence of O. luteopur- 
pureum showing a peculiarity analogous with the Dendrobium Wardianum 
described at page 95. The three lower flowers sent are normal in size, 
measuring over 33 inches diameter across the petals, but the next and 
remaining two flowers scarcely reach 2} inches in the same direction, while in 
colour they are as ill-developed as they are in size. It would appear that 
the food-supply was suddenly reduced by about half above the last normally 
developed flower, though the peduncle shows no apparent cause for this. 
It is as inexplicable as the case of Dendrobium Wardianum above alluded 
to, and the flowers present just as great a contrast. We should consider it 
to be an accidental circumstance, and not likely to be repeated another year.

EPIDENDRUM BITUBERCULATUM. 
It is not known to many that this Orchid is of terrestrial habit, and 
enjoys an exposed situation by the seaside. 
A year ago, while searching for fine specimens of Diacrium bicornutum 
(the old Epidendrum bicornutum), which grows down on rocks and trees 
by the seaside in Trinidad, the writer found fine, healthy patches of 
Epidendrum bituberculatum growing in the leaf-mould of the islands of the 
Bocas. These plants were far healthier than any seen before, and sturdier — 
than any grown on blocks or baskets or even found on trees, on these 
islands. The writer, taking this lesson from nature, has been very 
successful in cultivating this Orchid as a semi-terrestrial plant, in well- 
drained pots, with sand and fine leaf-mould. 
In its native home this Orchid can stand great heat and light, the 
temperature of the rocky promontory on which the plants were found being 
about 78° F. mean, and ranging from 72° to 89° F. 
They were found in bloom in February, growing among the long 
grass, the locality being then sparingly covered with thin and almost 
leafless brushwood.
