Beautiful hybrids are also obtained by crossing N. zanzibariensis 

 with N. capensis (blue), N. elegans (blue), and N.flavo-virens, the latter 

 yielding Grayae, 'W. Stone,' astraea, and gracilis purpurea. N. 

 zanzibariensis rosea and flavo-virens produce the pink or red hybrids, 

 Mauvii, 'Mrs. C. W. Ward,' astraea rosea, gracilis rubra, rosea perfecta, 

 and rosea. 



Castalia. The following are derived from A^. tetragona : crossed 

 with mexicana, pygmaea helvola and tetragona helvola, both yellow 

 flowers ; with alba, pygmaea alba, with alba rubra, Leydeckeri rosea. 

 N. odorata sulfurea and sulfur ea grandiflora are hybrids of mexicana and 

 odorata. N. ' Arc en ciel ' has sweet-scented salmon-coloured flowers. 

 It is a hybrid of odorata rosea. Many hybrids have been obtained 

 from alba ; bright yellow, Marliacea chromatella, chromatella, tuberosa 

 flavescens ; white alba candidissima and Marliacea albida ; pink, 

 Marliacea carnea, M. rosea, and'W. Doogue.' From N. alba rubra 

 are derived Robinsoni, Seignonetti, aurora, and fulva, with pink centres 

 and yellowish petals on the outside. A^. odorata rosea is one of the 

 parents of the pink-flowering caroliniana, c. perfecta, c. rosea, tuberosa 

 superba, odorata caroliniana, o. superba, and o. suavissima. Tuberosa 

 rosea, Brakeleyi rosea, and tuberosa rubra also have pink flowers. 

 N. colossea has large flesh-coloured flowers and is a persistent 

 bloomer. It is probably a hybrid of alba candidissima and odorata 

 rosea. 



The following are hardy : A'', chrysantha, N. aurora, N. Moorei, 

 N. Phoebus, and N. indiana, yellow ; ' Vesuvius,' * Sultan,' ' Attraction,' 

 * Darwin/ ' Froebelii,' and * Murello,' red ; ' Albatross,' ' Hermine,' and 

 ' Vomerensis,' white ; * Mrs. Richmond,' * OdaHsk,' ' GoHath,' and 

 ' Masaniello,' pink.— 5. E.W. 



Odontioda x * Coronation.' By Firmin Lambeau {Rev. Hort., p. 578, 

 Dec. 16, 1913 ; coloured plate). — ^The plate splendidly represents 

 this beautiful orchid, a bi-generic hybrid between an Odontoglossum 

 and Odontioda X Vuylstekei, the latter being itself a bi-generic one be- 

 tween Cochlioda Noezliana X Odontoglossum Pescatorei. The brilliancy 

 and delicacy of the colours and their arrangement defy description, and 

 the plants deservedly obtained the " Bull " Cup at our great Inter- 

 national Exhibition in 1912 for the most beautiful Odontioda.

Olive Oil, Deodorized {Rev. Hort. de I'Alg. March 1913, p. 121). 

 — ^A German patented process is being employed in the South of 

 France by which the commoner ranker olive oils, hitherto only suit- 

 able for industrial purposes may be transformed into an article of 

 food. The oil is neutralized, deodorized^ and the colour altered, and in 

 its refined form is invading the markets of Nice, Marseilles, and Salon 

 in increasing quantities. The question is now arising in the trade 

 as to whether there is really no chemical difference between these 

 artificially refined oils and the choice virgin product. — M. L. H.
