THE ORCHID REVIEW. 179 
PONTHIEVA MACULATA, 
A specimen of this remarkable and very pretty terrestrial Orchid has 
been received for determination from Alex. Hodgkinson, Esq., of The 
Grange, Wilmslow, Cheshire. The leaves of this Orchid are covered with 
long soft hairs, much like those of Arnica montana, and measure eight 
to twelve inches long, by one inch and a half to two inches broad. 
The spike is erect, one and a quarter to one and a half feet high, and 
the elegant flowers are borne in a lax raceme. The lateral sepals are white, 
spotted with greenish brown, and from the centre of each spot arises a 
glossy, appressed, unicellular, clavate hair, which is filled with colourless 
fluid, and so transparent that it is best seen with the aid of a lens. The 
dorsal sepal is pale brown with darker streaks, and the petals, which are 
pendulous from the top of the column, are united into a single organ, deep 
yellow in colour and with red-brown streaks, and on cursory examination 
might be mistaken for the lip, which is very small and fleshy. The lateral 
sepals are uppermost, and being the most conspicuous parts of the flower 
they impart to it a very remarkable appearance, even for an Orchid. It is 
certainly a striking and attractive little plant. It isa native of Venezuela 
and New Granada, and has been collected by Linden, Crueger, and Fendler, 
in the former, and by Funck and Schlim in the latter, in the province of 
Pamplona, at 7,500 feet elevation. Mr. Hodgkinson states that it has been 
grown at the cool end of the stove, potted ina mixture of fibrous loam, 
peat and sand, with a few finely-broken potsherds, and a moderate supply 
of water, and that the roots seem to die as soon as they leave the compost 
and enter the crocks. Being a terrestrial species it is probable that but 
little drainage is necessary.

CALENDAR OF OPERATIONS FOR JUNE. 
By W. H. WHITE, Burford, Dorking. 
THE long-continued spell of brilliant summer-like weather has been all that 
could be desired for the welfare of these plants, and I doubt if the majority 
of Orchids ever looked better than they do at this season, especially those 
Plants that occupy the warmest divisions. They seem to delight in their 
Natural sun-heat, growing and blooming more vigorously that in. our 
Ordinary spring climate. But with the colder growing species, it has been 
almost impossible to keep them anything like sufficiently cool, and where 
they are grown in houses exposed all day to the full glare of the sun, it has
