ZYGOPETALUM. 61 



country; and in 1857 Wendland collected it between Naranjo and 

 Carthago. It was shortly afterwards figured by Reichenbach in his 

 Xenia Orchidacea as Warsceiviczella discolor, the name by which it 

 is still best known in gardens; he afterwards merged it in Zygo- 

 petalum. It is very near Zijgopetalum marginatmn, from which it 

 is chiefly distinguished by its much narrower leaves and smaller 

 flowers, of which the petals are comparatively broader and the lip 

 differently lobed. 



Z. gramineum. 



Leaves radical, narrowly lanceolate, acute, conduplicate at base, 5 — 8 

 inches long. Peduncles clustered, slender, 2 — 3 inches long, one- 

 flowered, bi-bracteate at the base of the ovary, and with a single, 

 smaller subulate bract near the. base of the peduncle. Flowers 1^ inch 

 in diameter ; sepals and petals oval-oblong, light yellow-green with 

 lines of red-purple dots ; lip broadly ovate, concave, minutely denticulate 

 at the margin, yellow densely spotted on the disk with red-purple, 

 the spots smaller and fewer towards the margin ; crest a four-lobed 

 maroon-purple plate of peculiar shape not easily described.* Column 

 semi-terete, downy above, spotted like the perianth.

First detected by Hartweg about the year 1841 on the Pacific 

 side of the Western Cordillera of New Granada near Popayan^ but 

 not introduced by him. According to Reichenbachf it was shortly 

 afterwards found by Linden in Merida at 5,000 feet elevation, and 

 a few years later by Funck and Schlim in the same province. It 

 was subsequently collected in Caracas by Wagoner, by whom it was 

 introduced into Germany. On its flowering in German gardens 

 Reichenbach named it Kefersteinia graminea in compliment to Herr 

 Keferstein, at that time the possessor of one of the best orchid 

 collections in Germany, but afterwards restored it to Zygopetalum 

 to which it had been, in the first place, referred by Liudley. 



Z. graminifolium. 



Pseudo-bulbs al)out the size of a fil])ert, from a .slender creeping 

 rhizome, hearing at their apex 3 — 5 Hnear or linear-lanceolate,
