LIST OF COOL ORCUIDS. 115 



something like those of 0. Pescatorei, but larger, speckled 

 with brown ; two-leaved ; flower-spikes three to seven-flowered. 

 Flowers four to six inches across ; sepals and petals lanceolate, 

 the margins of the petals sometimes slightly jagged, of a bright 

 golden yellow colour, spotted with cinnamon brown ; lip white 

 with a lemon yellow centre, the apex tipped with purple rose. 

 This is rather rare, and will make a fine plant when well grown 

 for the spring and early summer exhibitions. I have seen 

 some fine varieties of this glorious species at Ferniehurst. 



0. Uro-Skinneri (Guatemala). — This is one of the easiest of 

 all Orchids to grow if properly treated. It affects a cool, 

 moist, and rather shady situation, and must be most liberally 

 supplied with water when growing. Its pseudo-bulbs are 

 thick, and bear broad lanceolate leaves, nine to twelve inches 

 long ; flower spikes simple, two to three feet high, bearing 

 ten to twenty flowers an inch and a half across ; sepals and 

 petals oblong, green, heavily barred with brown ; lip broad, 

 cordate, of a lively rose coloui* mottled with white, and having 

 a bilobed crest. Blooms about October or November, lasting 

 four to six weeks in flower. 



0. vcclllarliim. — We have here a decidedly novel, and much 

 to be desired species, but one at present rare in collections. 

 Its pseudo-bulbs are linear, two-leaved ; leaves, linear ligulate ; 

 flower-spike five to seven flowered ; sepals and petals about an 

 inch long, pure white, the lateral sepals having a single streak 

 of purple up the centre ; lip of enormous size, larger than that 

 of 0. Phalsenopsis, and decidedly flabellate, having a narrow 

 sagittate base; the lip, like the sepals and petals, is pure white, 

 tinged with delicate rose colour, the extreme base being tinged 

 with lemon yellow. The lip is quite two inches in breadth. 



0. Wallisii (New Granada). — Pseudo-bulbs ovoid, two-. 

 leaved ; leaves from nine to twelve inches long, very narrow 

 and Grass >^like ; spike erect or arching, from five to ten
