54 ONCIDITJM. 



as rare as it is curious. The species was dedicated to Comte 

 Alfred I.inimiughe, at tliat time one of the most liberal patrons of 

 Belgian horticulture. Our description is from a plant that flowered 

 in the collection of Mr. Lee, at Downside, Leatherhead, since 

 dispersed. 



Oncidium Limminghei belongs to the small section of the genus 

 of which On, Papilio is the type. The flowers are produced by 

 successive elongations of the rachis as in that species; the dorsal 

 sepal and petals are similar and of a duller colour than the other 

 segments, but not elongated as in On. Papilio and On. Eramerianum ; 

 they are also differently shaped from the lateral sepals, which are 

 brightly coloured. Another peculiarity is seen in the leaves, which 

 usually lie flat on the surface of the block to which the plant is 

 affixed; the mid-nerve is not the geometric diameter of the leaf, 

 but divides the blade into two unequal parts as in the Begonia 

 and Lime. 



On. longipes. 



Pseudo-bulbs ovoid, elongate, f — 1 inch long, in clusters of threes 



and fours from a slightly ascending rhizome as thick as an ordinary 



writing-pencil, mono- oftener diphyllous. Leaves linear-oblong, mucronate, 



4 — 6 inches long. Scapes as long as the leaves, 3 — 5 or more 



flowered. Flowers 1 — 1|- inches in diameter; sepals and petals pale 



red-brown streaked transversely with yellow and with yellow tips, 



spathulate or narrowly oblong, undulate, the lateral sepals longer and 



narrower than the dorsal one; lip bright canary-yellow, three-lobed, 



the side lobes roundish oblong, the front lobe transversely oblong, 



emarginate; crest an oblong fleshy disk covered with numerous small 



whitish warts, and with two prominent teeth in front. Column wings 



very narrow, almost obsolete.

Although one of the most frequently seen, and one of the most 



tractable of Oncids under cultivation, scarcely anything has been 



divulged respecting its origin beyond the statement that it was
