118 COOL ORCHID GEOTTIXG. 



bulbs being roundish ovoid, with a well-defined ridge up the 

 centre, like those of Laolia acuminata ; one-leaved ; spikes from 

 one to three feet long ; flowers from one and a half to 

 two inches across, it being very variable in size as well as in 

 colour ; sepals lanceolate, with wavy margins of a pale yellow 

 colour, barred with warm chestnut brown ; lateral sepals con- 

 nate for half their length ; petals oblong, with wavy margins 

 of a clear golden colour, streaked with crimson brown at the 

 base only ; lip triangular ; lateral lobes clear golden yellow, 

 margin of the discal portion fimbriate and spotted with brown ; 

 apical lobe rhomb if orm, clear yellow. This is a very variable 

 species, one or two of its varieties being equal to 0. bifolium 

 in colour, and much more easily grown. Some varieties have 

 their petals lanceolate, and barred with brown, like the sepals. 

 Flowers in June, July, and August, and blooms very freely in 

 a cool temperature. 



*0. bifolium. This is one of the best and most compact 

 species we have. Its pseudo-bulbs are one inch long, often 

 fluted, and spotted with brown; two-leaved ; leaves from three 

 to six inches long, dark green ; panicles drooping, many 

 flowered ; sepals and petals half an inch long, pale yellow, or 

 green barred with brown ; lip from one to one and a half inch 

 across, of the brightest golden yellow colour. This, together 

 with the still better form known as 0. bifolium ma jus, should 

 be grown in a shallow, well-drained pan, in peat and living 

 sphagnum, suspended close under the glass. 



0. crispum (Organ Mountains, Brazil). A free-flowering 

 species, having brownish fluted pseudo-bulbs, from one to two 

 inches high, two-leaved ; leaves oblong, often tinged with 

 bronze ; flowers from twenty to thirty, on an erect spike, and 

 two to three inches across ; the sepals and petals are of a 

 bronzy red or warm brown colour, very unique. Flowers in 

 winter, lasting four or five weeks.
