SCIIOMBURGKIA UNDULATA. 



A bold and remarkably handsome epiphyte, with stout fusiform pwiulobulta, «m mounted by a pair of thick oblonp 

 leave*, mid terminated brim elongated peduncle supporting a deitt» terminal raceme of brown and purple 

 flowers* The sepal* and |>etah are oblong-ligulate, much undulated and twisted at the edge, and of a deep 

 purplish-brown colour. The lip, which i* bent upwards parallel with the column, is cordate at the ba*e. 

 trilobed, the lateral lobe* purple, obtuse-angled, and turned up towards the column, the middle lobe oblong

This One plant was first found by the indefatigable traveller Linden, who gathered it in New Grenada, 

 at 2400 feet elevation, on rocks near Fandi. "the natural bridge of Icononzo." Wlien first flowered in 

 this country by Mr. Huckcr in 1SW, the spikes were small, some five- or six-flowered only, but M, 

 Linden's wild specimens bore as many as twenty flowers, so that something like the grand appearance it 

 presents in our Plate was confidently looked for amongst cultivator?, and may indeed be seen every year in 

 our collection at Ilroomficld. It is closely related as to habit to Sehomburgkia crispa and Sehomburgkia 

 tnarginata, but it differs from both these species by its very long, narrow, crisped sepals and petals. 



The genus Sehomburgkia was established by Dr. Lindlcy in the 'Scrtum Orchidaccum/ and "differs 

 from Epidendrum and its allies in having eight pollen-masses " The large size of the elongated pseudo- 

 bulbs is a characteristic feature of the species; indeed one of thctn, Sehomburgkia iibici*tis t which has 

 thick conical hollow pseudobulbs from one to Wo feet long, is the GowVhorn or Trumpet Orchis of 

 Honduras* The interior of the hollow pseudobulbs of this plant is as smooth as the hollow interior of a 

 bamboo stem, aud is often made the home of a colony of ants. Amongst the species introduced to our 

 gardens arc :— & crispa, from Dcinerara, with yellowish-brown crispy flowers and a white lip ; S. marginal^ 

 from Dcmcrara and Surinam, with purple flowers, yellow at the edge; & lihicims, from Honduras, with 

 rich reddish-purple flowers, nnd a beautifully marked orange lip, bordered with purple; 5. rwa, from 

 Santa Martha, with deep red flowers, having a rose-coloured lip, and said to he the glory of the genus ; 

 S. Lgonsii, from Jamaica, with charming white flowers, everywhere transversely barred with purple; nnd 



the NcwGrcnadan plant now figured, S* undulala. 



The subject of our beautiful illustration is of a compact nnd free-growing habit. The fusiform 

 IHCudobulbs and leaves grow from one to two feet or more in height, the latter being from two to three 

 inches broad, thick, and of a deep green colour. The flower stem, which rises from between the leaves at 

 the top of the pseudobulbs, is produced to a considerable length, and is terminated by ft spike or raceme 

 in which are borne some twelve or fourteen large handsome flowers* The sepals and petals arc of a 

 purplish-brown, with the margins beautifully waved or undulated; the side lobes of the lip are purplish- 

 lilac, the front lobe violet, with several raised white lines on its disc. The Dowers of this fine epiphyte
