acute, bronzy blackish brown with some green spots and markings ;

This is a recent addition to the section Euzygopetalum, having 

 for its nearest aflfinity Zygopetalum maxillarc, from which it is dis- 

 tinguished by its more slender rhizome, smaller pseudo-bulbs^ and 

 narrow grass-like leaves.* It was introduced by Messrs. Sander and Co. 

 from South Brazil, where it grows on the stems of Lomnria Boryana 

 and probably other tree-ferns. We are indebted to Mr. C. J. Lucas^ 

 of Warnham Court_, for materials for description, 



Z. grandiflorum. 



Pseudo-bulbs ovoid, furrowed, 2 — 3 inches long, diphyllous. Leaves 



broadly lanceolate, acuminate, upwards of a foot long. Scapes much 



shorter than the leaves, 3 — 5 flowered ; bracts ovate-lanceolate, acute, 



about half as long as the furrowed ovary, pale green. Flowers 3 inches 



in diameter ; sepals and petals broadly lanceolate, much acuminated, light 



green Avith 5 — 7 longitudinal brown bands ; lip broadly ovate, acuminate, 



three-lobed, the side lobes roundish oblong, erect, much lacerated at the 



margin, white ; the front lobe with dentate margin reflexed, white with 



10 — 12 longitudinal, red-purple raised lines; crest semi-circular, covering 



the basal third of the lip, ridged and furrowed, orange-yellow, the ridges 



red and with i)rojecting teeth in front. Column terete and white 



above ; wings oblong, projecting, the front margin fringed.

Originally introduced from New Granada by Linden, but we find 



no date or locality recorded. Among the earliest cultivators of this 



orchid in this country was the late Mr. Sigismund Eucker, in whose 



collection at West Hill, Wandsworth, it flowered in 1865, on which 



occasion the plant was figured in the Botanical Magazine. For 



* So far as regards these characters, tlie plant is sufiiciently distinct from Zygopetalum 

 maxillarc ; but in its floral characters it difl'ers so little as to suggest a doubt as to its 

 claim to specific rank. Its precise habitat is withheld, which precludes for the present any 

 hypothesis of its being a geographical form of Z. maj'illare.
