THE ORCHID WORLD 



this hybrid is the dark circle of colour at the 

 base of the lip, exactly under the crest. 



OdONTOGLOSSUM PaLMERI. — This pretty 

 new hybrid between Odontoglossum cnspo- 

 Harryanum and Od. Lambeauianum has 

 recently flowered m the collection of Thos. 

 W. Palmer, Esq., Woodlands, Walpole Road, 

 Boscombe, Hants. Although the plant is not 

 fully grown there is evidence m the flower that 

 a most useful addition to the Odontoglossum 

 hybrids has been made. The sepals and 

 petals are almost white, the latter very broad 

 and charmingly crisped at the margin, in fact, 

 the shape of the whole flower resembles that 

 of a good crispum more than the narrow 

 petalled one of Haxryanum. The Harryanum 

 has, however, left its influence in the bright 

 purple-red spots and markings which are 

 neatly arranged over the whole of the flower, 

 the only exception being' the apex of the 

 labellum, which is pure white. 



The following new hybrid Orchids were 

 included in the Gold Medal group exhibited 

 by Lieut-Col. Sir George Holiord, K.C.V.O., 

 at the Royal Horticultural Society, March 5th, 



igi2. They have all been raised by 

 Mr. H. G. Alexander. 



L.elio-Cattleya Voltaire (L.-C. C. G. 

 RCEBLING X C. AUREA). — The former parent 

 is a hybrid between L. purpurata and C. 

 Gaskelliana. This robust-growing hybrid 

 carried cl SpiK e of four creamy-white flowers, 

 the magenta-purple lip being veined with 

 gold at the base of the throat. 



Cattleya Magnet (Mossle x Whitei). 

 — C. Whitei IS a hybrid between Warneri and 

 Schilleriana. The form and colour of the 

 variety exhibited resembled a small flowering 

 W^arneri, but, doubtless, other varieties will 

 shortly appear. 



L/Elio-Cattleya Grolier (LABIATA X 

 MASSANGEANA).--The latter parent is a 

 hybrid between L. tenebrosa and C. Schil- 

 leriana. The flower is of a reddish-copper 

 colour, the lip somewhat darker and distinctly 

 veined with purple. 



L/ELio-Cattleya Argosy (Mossle x 

 Ingramii). — The latter parent is a hybrid 

 between L. Dayana and C. aurea. Flowers 

 of medium size, of a bright rosy-purple tint, 

 the distinctive feature being the large amount 

 of bright gold in the throat and on the side 

 lobes of the labellum. 



CALENDAR OF OPERATIONS FOR APRIL 



By J. T. BARKER, The West Hill, Hessle. E. Yorks. 



TEMPERATURES, generally speaking, 

 should a\erage from five to ten 

 degrees higher than those advised for 

 January, and even more on warm sunny days. 

 An exception, however, should be made with 

 the cool Odontoglossum house, a temperature 

 ranging between fifty and sixt)- degrees 

 should still be the aim, allowing, of course, a 

 slight rise with sun heat. The temperatures 

 should be kept as even as possible at night, 

 and sufficient fire heat must be maintained to 

 keep the different houses at their proper 

 figures. 



Atmosphere. With the increasing temper- 

 atures moisture ' may be distributed more 

 freely, as evaporation will take place more 

 quickly. The remarks made last month 



respecting this matter are available for April, 

 the only thing to bear in mind is that, as the 

 days get longer, the sun has more power, and 

 a hot, over-dry atmosphere must, above all 

 things, be avoided. 



Watering and venlihition during this month 

 need a great deal of care and attention, and 

 the remarks made last month under these 

 headings apply also to this. Attention in 

 these small matters makes all the difference 

 between success and failure. An inattentive 

 cultivator never reaches the highest position 

 in his profession, and whoever wishes to 

 become proficent in any form of plant culture 

 must attend to the smallest details. This 

 month we must push on with the re-potting 

 of all those plants which need it, taking each
