This plant appeared in 1862 in Director Linden’s garden, 
coming from 8. Paul, in Brazil. The specimens I obtained in 
1866 were widely different. The lip had been simply ovate-acute, 
now it was pandurato-oblong; it had had a horse-shoe lke green 
picture on its apex, now it was simply one-coloured; the whole 
appearance was widely different ; and yet, having seen more speci- 
mens, both in Mr. W. Wilson Saunders’ stoves and in the Ham- 
burgh Botanic Gardens, I have satisfied myself tat they are 
identical, and that we were deceived by a badly developed first 
specimen. Later, Director Linden named it proprio Marte a 
“ Habenaria”—not a very lucky combination; finally, Dr. E. 
Warming, now at Copenhagen, brought seven good herbarium 
specimens, a Danish description and a sketch, and an in- 
florescence in alcohol from Lagoa Santa, in Brazil. 
Roots fasciculate. Leaves rosulate-cuneate oblong acute, dark 
green, with many oblong rounded often lobed white shining 
blotches. Flower-stalk often more than two spans high, with 
many close acuminate bristly sheaths. Spike elongate, many- 
flowered, elegantly spiral, with the rhachis covered with glandular 
hairs; bracts equally hairy, one-nerved, lanceolate-setaceous,
