398 ORCHIDS 



Onoidium. 



and coloured creamy-white, with large spots of chestnut ; lip large, 

 broad, flat, with small, serrated, yellow side lobes, the blade white, 

 with a few crimson spots towards the base ; crest composed of 

 numerous yellow tubercles. When first introduced it was treated 

 as a cool-house plant, but it thrives best when grown on blocks 

 in a moist tropical house, in a rather sunny position. Its flowers 

 are developed at various times, usually in autumn and winter. 

 Paraguay, 1883. (B. M., t. 6982.) 



O. Kramerianum {Rchb. /.). — In gardens usually regarded as 

 a variety of O. Papilio, but by botanists as a distinct species. 



O. lamelligerum {Rchb. f.). — Flowers — dorsal sepal kidney- 

 shaped, wavy, stalked, deep brown, bordered with yellow ; lower 

 sepals longer, stalked, oblong, unequal at base ; petals broadly 

 clawed, yellowish, patched with brown. Ecuador, 1876. 



O. Lanceanum {Li?idL). — As a garden plant this beautiful, 

 fragrant, and large-flowered species, has a bad reputation. It 

 has no pseudo-bulbs, the leaves springing directly from a stout 

 rhizome. Each leaf is ift. or more in length, about one-fourth 

 as broad, thick, leathery, green, thickly spotted with brown. 

 The flower-spike is stout, erect, branched, ift. or more in height, 

 and bears numerous flowers, which are from 2in. to 3in. across ; 

 sepals and petals equal, ovate, lin. long, fleshy, yellow, barred 

 and blotched with chocolate-brown ; lip iMn. long, narrowed and 

 waist-like in the middle, the apex spreading and flat, tin. broad; 

 colour variable, but usually rosy at the base and violet on the 

 broad part. The flowers remain fresh about a month. The 

 plant requires moist, tropical treatment, except during the two or 

 three winter months, when a dry position in the intermediate- 

 house is best. It should be planted in well-drained baskets or 

 pans, in a mixture of peat and sphagnum. It likes a very high 

 temperature whilst making new growth. Unfortunately, it is 

 often badly affected by " Spot," and soon gets too weak to make 

 good growth. It flowers usually in summer. Dutch Guiana, 

 1834. (Fig. 135; B. R., t. 1887.) 



O. leucochilum {Batem.). — An old favourite, of noble habit, 

 beautiful in flower, and showing considerable variation. Pseudo- 

 bulbs ovate, flattened, furrowed, 2lrin. long, one- or two-leaved. 

 Leaves gin. long, lin. broad, pointed and recurved. Flower- 

 spikes long, arching, panicled ; flowers numerous, 2in. across, 

 with equal sepals and petals, oblong in shape, tin. in length, 

 and coloured yellowish-green, with blotches of dark brown ; lip 

 kidney-shaped, |in. across, with a red, stalk-like base, the blade 

 two-lobed, pure white, turning to yellow with age, the two small
