116 COOL OllCniD GROWING. 



flowered. Flowers two or three inclies across, very showy ;. 

 sepals and petals oblong, about one inch long, of a golden 

 yellow, blotched with rosy purple ; lip straw coloured, with a 

 rosy blotch near the apex ; crest, margin, and apex white ; lip 

 partially adnate to the column, as in the old 0. epidendroides 

 (0. Lindleyanum), of which very variable species it is not 

 improbably a finely coloured form. It is one of Wallis's intro- 

 ductions to the establishment of M. Linden. 



0. zehrinum. — This is a curious plant, having the habit 

 of Oncidium macranthum. Flower-stems from five to six 

 feet long, flexuose, and branched in the same manner as those 

 of the last-named species. Its flowers are of moderate size, 

 one to one and a half inch across ; sepals and petals equal,, 

 white, very much crisped or wavy, and barred with brown, 

 the white lip having a large corrugated golden crest, quite 

 unlike any other Odontoglot or Oncid I have seen. Flowers 

 in August and September, lasting a considerable time. This 

 plant also goes under the name of Oncidium zebrinum. 



Oncidium. 

 This genus, if we except the Epidcndrums, is perhaps the 

 most numerous in species, and many of them are more or less 

 adapted for growing in the cool Orchid house. Amongst the 

 latter must be enumerated the truly noble 0. macranthum, 

 one of the finest of all Orchids, O. serratum, 0. crispum, 0. 

 cucuUatum, O. Phala3nopsis, O.nubigenum, and 0. splendidum, 

 nob to mention others equally beautiful. Most of the Oncids 

 are remarkable for producing a profusion of golden yellow 

 flowers more or less blotched with brown, and they are for 

 the most part of easy culture. The larger growing species 

 will succeed in the compost recommended for Odontoglots, 

 and should be grown in pots. The smaller kinds, as 0. 

 cucullatum and its varieties, may either be grown in shallow
