the white C. aurea, known as C. Imschootiana. Cymbidiian 

 Tj'acyanuin is a big-flowered C. Hookerianum, the older name 

 for which is C. graudifloj'inn. Three new sobralias, named 6". 

 Lowii, S. Sandercp and S. Wilsoni differ only slightly in color 

 from species already known in gardens. There are only two 

 newly introduced cypripediums — C. Schoinburgkii and C. Sia- 

 inense — and these are scarcely more than botanical curiosities. 

 The same may be said of the seven new species of masdeval- 

 lia. This genus is attracting an unusual amount of attention 

 just now, as is shown by the fact that more new species have 

 been introduced lately than of any other genus of orchids. 

 The pick of the lot is AI. Lowii, which has the habit of M. 

 Chimcura, tailed flowers, three inches across, and white with 

 purple spots. Varieties of species already established in gar- 

 dens continue to appear among the numerous plants annually 

 imported, and some of these are valuable. Cattleyas have 

 produced C. Lawrenciana, var. Vinckii, with flowers of a de- 

 cided bluish or magenta hue ; C. aurea, var. Imschootiana, with 

 white sepals and petals and a richly colored lip ; C. gra?mIosa, 

 var. Buyssoniana, with white sepals and petals. Laelias have 

 revealed several excellent varieties, particularly in Z. prcsstans, 

 alha and L. elegans, Broonieatia. 



''Hybrid orchids eclipse in beauty and interest the new in- 

 troductions. Best of all is Fhaius Cooksoni, a hybrid between 

 P. tiiberculosiis and P. Wallichii, raised by Mr. Norman Cook- 

 son. It has the constitution of the latter parent and the ek*- 

 gance of the former, plus a rich rosy color. This orchid ought 

 to prove a useful garden plant. Equaling the phaius in in- 

 terest is the h3'brid Odoutoglossiim Leroyaniun, raised by M. 

 Leroy, gardener to Baron E. de Rothschild, at Gretz, its 

 parents being O. crispuin and O. luteo-piirpureiiin. It is the first 

 hybrid odontoglossum originated in the garden. Equally in- 

 teresting are the two bigeneric hybrids produced and flowered 

 last year by Messrs. J. Veitch & Sons — namely, Epiphro7iitis 

 Vcitchii and SopJiro- Cat t ley a Calypso. Masdevallia stella is an ad- 

 ditional hybrid in this genus. Dendrobiums have produced 

 several beautiful hybrids, those exhibited by Sir T. Laurence 

 at the beginning of the year being at least as beautiful and in- 

 teresting as the best of those previousl}^ raised ; they are named 

 Juno, Luno, Chrx'sodiscus and Melanodiscus. Something like 

 thirty hybrids have been added to cypripedium, and, whilst a
