constant. In On. Kramerianum the pseudo-bulbs are more orbicular 

 and often smaller, the leaves shorter and less profusely spotted ; the 

 peduncles are shorter with the nodes at shorter intervals, not flattened 

 and aucipitous above. The flowers are generally a little smaller with 

 the upper sepal and petals shorter and differently coloured ; the claw 

 or isthmus of the front lobe of the lip is shorter and the blade is of 

 a brighter colour than in On. Papilio. 



On. lamelligerum. 



Pseudo-bulbs elongate-ovate or flagon-shaped, 4- -6 inches long, di- 



phyllous. Leaves hnear-ligulate, acuminate, 15 — 20 or more inches long. 



Scapes 5 — 7 or more feet long, flexnose, distantly branched, many 



flowered. Flowers 3 inches across vertically; sepals clawed, light brown, 



the upper one sub-orbicular with crisped yellow margin ; the lateral two 



divergent, longer than the upper one, ovate-oblong, obtuse, keeled behind 



and more or less incurved; petals clawed, ovate-oblong, sub-acute, much 



crisped towards the apex, the basal half light brown with some narrow, 



tranverse, yellow streaks, the apical area light yellow; lip linear-oblong, 



acute, light yellow stained with pale purple, the basal lobes oblong, 



denticulate, concave, purple ; crest white, consisting of an acute edged

Discovered by Edward Klaboch in Ecuador in 1875 — Q, and introduced 



to European gardens shortly afterwards. It flowered for the first 



time in this country in the autumn of 1878, in the collection of Mr. 



Charles Dorman, at The Firs, Sydenham ; it has since flowered in 



several collections, the flowers in some instances showing slight 



deviations in colour from the first introduced type. For materials for 



description we are indebted to Mr. Charles Winn, of Selly Hill, 



Birmingham, and to Messrs. Charlesworth and Shuttleworth, of 



Bradford and Clapham. 



On. Lanceanum, 



Pseudo-bulbs none. Leaves from a stoutish rhizome, elliptic-oblong, 

 12 — 18 inches long and 3 — 5 inches broad, erect, coriaceous, deep dull 

 green more or less spotted with purple. Scapes from the base of the 

 latest formed leaves and longer than them, erect, panicled above. Flowers 

 numerous, 2 — 2^ inches in diameter, very fragrant ; sepals and petals 

 similar, oval-oblong, obtuse, yellow or yellow-green much spotted with 

 chocolate-brown ; lip usually dark purple or rose-purple, less frequently 

 with the front lobe white, three-lobed, the side lobes triangular-oblong,
