some particular habitat. In South America, many Orchids affect the 

 trunks of tree-ferns or of Cresceutia Cujete ; others are found on 

 Pandanus, &c. 



M. Jacob de Cordemoy has made a study of the relations existing 

 between the Vanilla plant and its support, and he has communicated to the 

 Academy of Sciences at Paris, the result of his observations. He concludes 

 that there exists between the lateral and aerial roots of the Vanilla and the 

 support to which they cling, a mycorhiza, or a combination of the roots 

 with an endophytic fungus. The endophyte throws out a ramified 

 mycelium, which forms a strict connection between the lateral roots and 

 its living support. This morphological connection probably corresponds to 

 some physiological connection, the Fungus being able to find in the tissues 

 of the living support certain nutritive principles useful to the growth of the 

 Orchid. In this case theie would be a real symbiotic connection existing 

 between the mycorhiza and the roots of the Orchid. — Revue Horticole. 



THE HYBRIDIST. 



Lj2LIO-cattleya X Glycera.— A year ago we received from the collec- 

 tion of Reginald Young, Esq., Sefton Park, Liverpool, the inflorescence of 

 a very pretty little hybrid between Cattleya Trianae and Laelia rupestris, 

 but owing to pressure it failed to get recorded. Mr. Young has now again 

 sent a three-flowered inflorescence, showing it to be a very charming little 

 plant. Laelia rupestris is a rare Brazilian species closely resembling 

 L. flava in almost every respect but that of colour, but its flowers are deep 

 purple. The hybrid most resembles this parent, the inflorescence sent 

 being a foot long, and the flowers having an expanse of 3| inches. The 

 sepals and petals are widely spreading, lanceolate oblong in shape, and 

 deep lilac-purple in colour; while the front of the lobe is much deeper 

 purple, very crispo-undulate, and but little expanded — as in hybrids of 

 L. cinnabarina— and the disc and side-lobes are lilac veined with purple. 

 The pollinia are those of Laelio-cattleya, four large and four small, and the 

 influence of the Cattleya parent is also seen in the increased size and 

 modified details, but in floral characters it most resembles the Laelia parent. 

 It is a charming little plant. An inflorescence of the same hybrid was 

 exhibited at the last meeting of the R.H.S., from the collection of the Hon. 

 Walter Rothschild, M.P. 



Dendrobium X MYRA. — A very pretty hybrid from the collection of Sir 

 Trevor Lawrence, Bart., derived from Dendrobium Linawianum J and 

 D. signatum S, which was exhibited at the last meeting of the R.H.S. 

 The flower is bright buff-yellow, with a claret-purple disc, and a deep-
