1U4 COOL ORCHID GROWING. 



0. pendulum of Lindley, introduced from Guatemala iu 

 1840; pseudo-bulbs large and shining, two-leaved. Flower- 

 spikes pendulous, bearing from fifteen to thirty large fragrant 

 blossoms. It flowers in May and June, and lasts a month in 

 perfection. This species will be found to grow best in the 

 warm end of the house, among the Cattleyas and Miltonias. 



a. *0. cltrosmmn roseum. — A noble form of the above, having 

 large rosy-tinted sepals and petals and a rosy -purple lip. A 

 plant of 0. citrosmum roseum in the collection of Dr. Ains- 

 worth, of Higher Broughton, near Manchester, has borne 

 fifty-two flowers on a single-branched spike. Mr. W. Mitchell 

 grows this plant, Miltonia Warscewiczii, and Oncidium sarcodes 

 remarkably well. He has had 0. sarcodes in a cool conserva- 

 tory with from fifty to seventy flowers on a spike. 



0.cor(^«^m)i( Guatemala, Mexico, 1837). — Pseudo-bulbs oblong, 

 generally one-leaved ; leaves bright green, with yellow lines ; 

 scape simple, erect, bearing from ten to fifteen flowers. Flowers 

 from two to three inches across ; sepals and petals nearly 

 equal, lanceolate, apices very much acuminate, of a yellow 

 colour, barred and blotched with soft brown ; lip cordate, 

 white, with a few brown blotches. This species is very 

 variable in the depth and richness of its markings, and has 

 often been confounded with 0. maculatum, a totally different 

 species. This is a free-flowering and easily-grown kind, 

 blooming in May, and lasting three or four weeks. 



0. coronarium. — This is one of the coolest species we have, 

 coming from the Andes of Peru, at an altitude of 8,000 feet. 

 Its large, wrinkled, flat bulbs are produced at intervals along 

 a creeping rhizome, and bear a short oblong leaf at the apex. 

 Flower-spike erect, from twelve to sixteen inches high, bearing 

 about thirty or forty flowers ; sepals and petals bright 

 brown, margins yellow ; lip of a bright golden colour. Lasts 

 a long time in flower. This plant flowered in 1872 in
