ONCIDIUM. 53 



This species, if species it is, was first described by Dr. Kegel in 

 the Gartenflora for 1881 from plants sent to the Imperial Botanic 

 Garden at St. Petersburg from Brazil by Lietze. A variety is 

 figured in the Gartenflora of 1887 under the name of aureo-macu- 

 latum which differs from the type iu the floral segments being 

 spotted with yellow ; a third variety named hicolor is also 

 mentioned. Dr. Eegel compares Oncidium Lietzei with On. amictum, 

 Lindl., figured in the Botanical Register for 1847 which we have 

 mentioned under On. Gardneri, but it is much nearer On. jpnhes, 

 so near indeed that, when more ample materials for comparison are 

 available, it may hereafter be reduced to a variety of that species. 

 Our description was taken in the Spring of 1890 from a plant in the 

 collection of Mr. F. G. Tautz at Hammersmith, since dispersed. 



On. Limminghei. 



Pseudo-bulbs roundish, compressed, f inch in diameter, rugose, rnono- 



pliyllous. Leaves sessile, ovate, oblique, acute, 1 — 1|- inches long, dull 



green speckled with crimson. Peduncles filiform, 4 — 5 or more inches 



long, bearing 3 — 5 flowers that expand in succession, each flower 



1 J inches in diameter ; dorsal sepal and petals similar and equal, oval, 



obtuse, slightly undulated, tawny brown with a paler margin ; the 



lateral sepals smaller than the dorsal one, with which they are united 



at their base, light yellow barred with red-brown ; lip with two rounded 



basal auricles that are yellow spotted with red ; the blade transversely 



oblong, emarginate, bright yellow with some red spots near the anterior 



margin ; crest an elevated plate with two smaller parallel lamellas 



behind. Column wings bipartite, pectinate, the superior part the 



smallest and incurved.

A very interesting species that first became known to science and 



to horticulture through the late Professor Morren, of Liege. Plants 



were sent to Belgium from Caracas,* by the Dutch Consul, M. Van 



Lousberghe, one of which flowered in the Botanic Garden at Liege, 



in August, 1855, whence it was communicated to Dr. Lindley by 



Professor Morren in time for insertion in the Monograph of Oncidium 



in the Folia Orchidacea, published in October of that year. Since 



that time it has been sparingly imported, but it is believed to be 



* It is extremely doubtful whether this Oncid is a native of Caracas. The precise habitat ia 

 probably known only to the collectors who send it to Europe from that port.
