the flowers are in shape vei-y like diminutive examples of that species. The 

 pseudobulbs are small narrow-oblong, compressed, smooth, the leaves solitary 

 linear-oblong acute, and the flowers in simple erect or nodding racemes on very 

 slender scapes ; the sepals and petals are small ovate acute, white or dull purple 

 with green tips, and the lip is broader than long, the front lobe almost reniform, 

 white with purple blotches, and three small calli at the base, but in the manner 

 of its markings and the intensity of its colour it appears to be very variable. — 

 Ecuador.

 growing freely in the cool house. The pseudobulbs are oblong-ovate compressed, 

 monophyllous, with accessory basal leaves, oblong-ligulate in form ; the flowers

 barred with brown, and yielding a delicious perfume; the branches of the 

 panicle are short and flexuose, the sepals and petals are all reflexed, and the lip, 

 which has a long claw-like isthmus and a broad reniform two-cleft anterior lobe, 

 is clear yellow with an orange-red stain about the crest. There are many

O. ORNITHORHYNCHUM, Rumholdt, Bonjjland, el Kunth.—A pretty free- 

 flowering species, which has ovate-oblong compressed two-leaved pseudobulbs, 

 ensiform acuminate leaves, and crowded gracefully drooping panicles, a foot long 

 or more, of small but fragrant flowers of a clear rose, deeper in some forms than
