0. pulvi7iatum majus. — A fine Brazilian variety of the pre- 

 ceding, growing in the same way, but having blossoms much 

 larger and brighter in colour. This I have only seen in the 

 late collection of E. McMorland, Esq. 



0. refiexum. — This handsome Mexican Oncidium should 

 find a place in every collection. Its dwaif habit, easy culture, 

 and the numerous long spikes covered with abundance of its 

 large bright yellow flowers, which enliven the house as autumn 

 is approaching, should make it a universal favourite. 



0. Rogersii. — This exceedmgly showy and beautiful free- 

 flowering species should be grown in the Cattleija house, 

 potted in peat and sphagnum moss. In habit and appearance 

 it resembles 0. hifoHum majus, but is more robust than that 

 plant, and the spike is also much larger and branched, bearing 

 as many as one hundred and seventy flowers, which mea- 

 sure about two and a half inches across ; sepals and petals 

 small ; lip large, flat, and spreading, deeply three-lobed in 

 front, and rich golden yellow in colour. It blooms during 

 winter, and is said to be a variety of 0. varicosum. This is 

 well illustrated from Mr. Veitch's plant in " Warner's Select 

 Orchidaceous Plants,'' Second Series. Native of Brazil. 



O. roseum. — A pretty small-flowering species from Hon- 

 duras. The flowers are rose-coloui*ed, spotted with red ; it 

 blooms at difi'erent times of the year, lasts six weeks in good 

 condition, and is best grown in a pot with peat. 



0. roseum superhum. — This is a fine large variety of the pre- 

 ceding, which I saw in the collection of the late T. West, Esq., 

 Clapham Park ; it is a magnificent plant, making spikes 

 five feet long, covered with its beautiful large rich crimson and 

 white flowers. 



0. rupestre. — A very handsome cool-house species ; the 

 pseudobulbs are smooth and stout, pale green ; leaves ligu- 

 late, about a foot long, and dark green ; flowers numerous,
